Description

  The present invention relates to a lighting fixture.

  Conventionally, when attaching a fixture such as a lighting fixture to a wall surface, the front and rear surfaces of the fixture body that constitutes the fixture main body are divided into the fixture body integrally inside the fixture body where the front opening and the rear opening are provided. And an insertion hole that opens in the front and rear direction is formed in the partition portion, and a screw rod protruding from a wall surface mounting plate attached to the wall surface is inserted into the insertion hole of the intermediate partition portion from the rear opening portion of the instrument body. With the front cover attached to the front opening of the main body removed, the instrument main body is attached by screwing the cap nut into the tip of the above screw rod that is inserted through the insertion hole through the front opening. One is known from US Pat.

  In the conventional example shown in the above-mentioned Patent Document 1, when attaching the instrument body to the wall surface, put a hand through the front opening of the instrument body opened in the same direction as the opening direction of the insertion hole through which the screw rod is inserted. Since the cap nut is screwed and attached to the tip of the screw rod, when the fixture body is a lighting fixture, the front opening for performing the fixture work is also used as an opening for replacing the lamp, and If the front cover attached to the front opening is a light-transmitting plate that transmits the light of the lamp, it is inevitably a direct illumination in which the light of the lamp is irradiated forward from the front opening, and an indirect illumination can be obtained. Can not.

  By the way, a round lamp, an annular lamp, or a straight tube lamp is generally used as a lamp of a lighting fixture. In the above-described conventional example, these generally used round lamps or annular lamps are used. When the lamp or straight tube lamp is provided in the instrument body, there is a problem in that a lamp image of a round lamp, an annular lamp or a straight tube lamp can be seen on the front cover portion.

  To improve the lamp image generated on the front cover, it is necessary to keep the distance between the lamp and the front panel more than a predetermined distance so that the lamp image does not appear on the front panel. If the distance from the panel is more than a predetermined distance that does not cause a lamp image, there is a problem that the instrument body becomes thick, and conventionally, the front cover is exposed to the front.

Further, in the conventional example shown in Patent Document 1, since the screw rod is inserted into the insertion hole and screwed with the cap nut, the mounting is performed. In the state where the screw rod is inserted into the insertion hole, the insertion hole portion may slide down from the screw rod, and temporary support until the screw rod tightening operation cannot be stabilized. In this state, there is a problem that the mounting operation becomes troublesome because an operation of screwing the cap nut onto the tip of the screw rod must be performed while supporting the device main body by hand so that the instrument body does not slide down.
JP 2006-189083 A

  The present invention was invented in view of the above-described conventional problems, and can be reduced in thickness without generating a lamp image, and the lamp can be replaced by using an opening for performing the mounting operation of the instrument body. Also provided is a lighting fixture that can be used for indirect illumination with little lamp image and light unevenness through a translucent panel attached to the opening, and can be temporarily supported when attaching the fixture body to the wall surface, making installation work easy. It is an object to do.

  In order to solve the above-described problem, the lighting fixture according to the present invention is provided with the mounting opening 11 through which the mounting plate 30 is inserted on the mounting surface 7 side of the fixture main body 1 and the opening direction of the mounting opening 11 in the fixture main body 1. A lamp replacement opening 28 for exchanging orthogonal flat lamps 3 is provided, and a block cover 14 for supporting the instrument main body 1 is provided in the instrument main body 1 at a position pulled inward from the lamp replacement opening 28. 6 is inserted into the mounting opening 11 and the block cover 14 is fixed to the mounting plate 30 to mount the fixture body 1, and the translucent panel 17 that closes the lamp replacement opening 28 is attached to the fixture body. The translucent panel 17 is placed in a state in which the translucent panel 17 is not inserted into the mounting opening 11 at a position where the translucent panel 17 is drawn inward from the opening end of the lamp replacement opening 28. It is characterized in that comprising removably attached to the mounting plate 30 by attaching means 35.

  By adopting such a configuration, by inserting the mounting opening 11 into the mounting plate 30 to be mounted on the wall surface 6, the fixing tool 33 is inserted using the lamp replacement opening 28 while being temporarily supported by the mounting plate 30. Thus, the work for attaching the instrument body 1 can be performed. In addition, since the fixture main body 1 is provided with a lamp replacement opening 28 for replacing the flat lamp 3 orthogonal to the opening direction of the mounting opening 11 and the lamp replacement opening 28 is closed by the translucent panel 17, the flat lamp In addition to the effect of reducing the light unevenness due to the use of 3, even if the distance between the flat lamp 3 and the translucent panel 17 is shortened, it is difficult to generate a lamp image via the translucent panel 17, and the lamp replacement opening Thus, indirect illumination with little lamp image and light unevenness can be achieved through the translucent panel 17 attached to 28. Moreover, the translucent panel 17 that closes the lamp replacement opening 28 is in a state where the translucent panel 17 is not inserted into the mounting opening 11 at a position lower than the opening end of the lamp replacement opening 28 of the fixture body 1. Since the translucent panel 17 is detachably attached to the attachment plate 30 by the attachment means 35, the end of the translucent panel 17 is attached to the attachment opening 11 when the translucent panel 17 is attached to the attachment plate 30 by the attachment means 35. Accordingly, the translucent panel 17 can be attached to the mounting plate 30 in a state where the lamp replacement opening 28 is securely closed without being inserted into the lamp replacement opening 28.

Further, the translucent panel 17 has a surface processed so that the center part is polarized so that the lamp light is polarized forward, which is opposite to the wall surface 6, and the side part is surface-treated so that the side part is polarized above the instrument body 1. Preferably there is.

With such a configuration, among the lamp light irradiated through the light transmissive panel 17, the lamp light emitted from the central portion of the translucent panel 17 is polarized in the forward in the opposite direction and the wall surface 6 As a result, it is possible to effectively irradiate the ceiling surface away from the wall surface 6 and the space near the ceiling surface away from the wall surface 6, and the lamp light emitted from the side portion of the translucent panel 17 is It is irradiated so as to be polarized upward, so that the ceiling surface close to the wall surface 6 can be effectively irradiated, so that the ceiling surface away from the wall surface 6 and the space near the ceiling surface away from the wall surface 6, the wall surface Each of the ceiling surfaces close to 6 can be effectively illuminated.

  The translucent panel 17 is preferably attached to the instrument body 1 so as to be rotatable.

With such a configuration, the light transmitting panel 17 is provided with a polarization, with a simple configuration, it can be easily irradiated with light in the direction of aim lamp light irradiated through the light-transmitting panel 17 .

  Since the present invention is configured as described above, since the lamp replacement opening for replacing the flat lamp perpendicular to the opening direction of the mounting opening is provided in the fixture body, the space between the flat lamp and the translucent panel is provided. The lamp image is less likely to be generated through the translucent panel even if the lamp is shortened, and the lamp image and indirect illumination with less light unevenness can be achieved through the translucent panel attached to the lamp replacement opening. In the state where the fixture body is temporarily supported during the installation of the main body, the lamp replacement opening can be used to attach the lighting fixture main body to the mounting plate, and the lamp replacement opening can be used to transmit light. The panel can be easily mounted on the mounting plate.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  A lighting fixture 9 according to the present invention includes a terminal block 29, a lighting block 12 including a ballast 4, a block cover 14, a lamp support spring 16, a lamp socket 5, a translucent panel 17, and a fixture. An attachment plate 30 for attaching the main body 1 to the wall surface 6 and a flat lamp 3 arranged and attached in the instrument main body 1 are configured.

  As shown in FIGS. 1 and 2, the fixture body 1 constituting the main body of the lighting fixture 9 has a flat and thin box shape that is thin in the vertical direction. In the embodiment shown in the accompanying drawings, the fixture body 1 has a rectangular shape in plan view. It is a thin box.

  Most of the instrument main body 1 in the shape of a thin box having a square shape in plan view is a main storage portion 13 opened to the upper surface side or the lower surface side. One side portion of the instrument body 1 is an attachment portion 7 that is a side to be attached to the wall surface 6, and the attachment portion 7 that is to be attached to the wall surface 6 is a recess 38 that opens to the side. The main storage portion 13 is partitioned by a partition wall portion 10, and a slit-like mounting opening 11 that communicates the recess 38 and the main storage portion 13 with the partition wall portion 10 at the upper end portion of the partition wall portion 10. Is formed.

  The lighting block 12 including the ballast 4 is disposed at a location biased toward the partition wall 10 in the main storage portion 13 of the appliance main body 1 and is fixed by screws 49.

  The block cover 14 has a block cover portion 15 which is a recess opened on the back surface side, and a flat lamp arrangement portion 8 which is a recess opened on the front surface side. The block cover 14 is placed in the main storage portion 13. In a state where the lighting block 12 is covered with the block covering portion 15, the block cover 14 is attached to the instrument body 1 by a fixing means 50 such as a screw.

  The flat lamp 3 is arranged and attached to the flat lamp arrangement portion 8 located adjacent to the block cover portion 15 of the block cover 14.

  Here, the main storage portion 13 of the instrument main body 1 is open on the upper surface side or the lower surface side as described above, and the opening on the upper surface side or the lower surface side provided in the main storage portion 13 is the opening direction of the mounting opening portion 11. The opening of the main storage portion 13 is a lamp replacement opening 28.

  A panel for supporting a part of the translucent panel 17 when the translucent panel 17 is attached to the inner wall surface of the main housing portion 13 so as to shield the lamp replacement opening 28 by the translucent panel 17 described later. A support portion 39 is projected.

  A pair of a lamp socket 5 and a lamp support spring 16 is provided at each corner which is a pair of opposing corner portions in the flat lamp arrangement portion 8.

  As shown in FIG. 3, the flat lamp 3 is formed such that the arc tube 2 is formed so that the discharge path rotates in a double spiral shape around the intermediate portion in the longitudinal direction of the tube in the same virtual plane. The flat lamp 3 is formed as a whole including the central portion when viewed from the direction facing the spiral of the arc tube 2 (the direction facing the virtual plane). It is a planar light-emitting body which reveals the state which light-emits planarly. Therefore, it is smaller and brighter than a lamp having an annular arc tube. In addition, an intermediate portion in the length direction of the arc tube 2 that becomes the center of the double spiral is formed thicker than the other portions, and a part of the middle portion protrudes to one side of the flat lamp 3. This projecting portion 2a is the coldest point of the arc tube 2, whereby stable light emission of the flat lamp 3 can be realized.

  The pair of caps 18 provided on the arc tube 2 are arranged at point-symmetrical positions around the center of the double spiral arc tube 2 in front view. The length of the arc tube 2 positioned between each base 18 and a part in the length direction of the arc tube 2 located inside the cap 18 and inside the same part as the length direction of the arc tube 2 A part of the direction is filled with a filler 19, and the pair of bases 18 are connected to each other by a bridge 20 disposed on one surface side of the flat lamp 3. Thus, deformation of the double spiral flat lamp 3 is prevented. Further, the filler 19 provided between each base 18 and the arc tube 2 and between the arc tubes 2 is provided on the surface of the bridge 20 on the flat lamp 3 side and overlaps the bridge 20 in a front view. The area where the arc tube 2 is blocked by the filler 19 and the bridge 20 is small, and the loss of light is small.

  Two lamp pins 21 that are parallel to each other are projected from the end face of each base 18, and the protruding direction of the lamp pin 21 provided on one base 18 and the protruding direction of the lamp pin 21 provided on the other base 18 are opposite to each other. It has become. A pair of lamp pins 21 of each base 18 protrudes from the center of the end face of the circular base 18 and is orthogonal to the surface of the flat lamp 3 that emits light in a flat shape (that is, the same virtual surface on which the arc tube 2 is disposed). Are arranged in parallel.

  The lamp socket 5 has a substantially C-shaped cross section that is rotatably housed inside a socket main body 22 fixed to the block cover 14 and a cylindrical holding portion 23 that opens to the base 18 formed in the socket main body 22. A rotating body 24 is housed so as to be rotatable so that the state shown in FIG. 4 (a) can be changed to the state shown in FIG. 4 (b). An operation lever 26 that protrudes through a notch 25 formed in the front wall portion of the holding portion 23 is provided at the circumferential end of the rotating body 24. A pair of contacts (not shown) are fixed on the inner surface of the rotating body 24.

  In the flat lamp 3, the flat lamp 3 is inserted into the flat lamp disposition portion 8 from the lamp replacement opening 28 of the main storage portion 13, and the lamp pin 21 provided on the base 18 of the flat lamp 3 is electrically and mechanically connected to the lamp socket 5. And the arc tube 2 or the base 18 is attached to the lamp support spring 16.

  In order to connect the flat lamp 3 to each lamp socket 5, the flat lamp 3 is opened to a pair of caps 18 with the C-shaped rotating body 24 opened upward as shown in FIG. The lamp pin 21 is inserted into the rotating body 24 (in this case, it is temporarily supported by the lamp support spring 16 at the same time), and then the operating body 26 is operated to rotate the rotating body 24. The pair of lamp pins 21 is held by the contacts, and the pair of contacts and the pair of lamp pins 21 are electrically connected. The connection between each lamp socket 5 and the flat lamp 3 is reversed in the above operation.

  As described above, the pair of lamp pins 21 of each base 18 is rotated around the lamp socket 5 simply by moving the flat lamp 3 in the same direction as the insertion direction in which the flat lamp 3 is inserted from the lamp replacement opening 28 into the flat lamp disposition portion 8. Since it can be inserted inside the moving body 24, the flat lamp 3 and each lamp socket 5 can be easily connected. Further, since the pair of lamp pins 21 of each base 18 are arranged side by side in a direction orthogonal to the plane parallel to the flat lamp 3, the width dimension of each base 18 can be shortened when viewed from the front, and the flat lamp 3 is viewed from the front. 1 can be reduced, and the width dimension of each lamp socket 5 indicated by L in FIG. 1 can be shortened, so that the area of the lamp socket 5 viewed from the insertion direction of the flat lamp arrangement portion 8 can be reduced. In this case, the filament (not shown) provided between the pair of lamp pins 21 of each cap 18 in the arc tube 2 is arranged so as to be orthogonal to a plane parallel to the flat lamp 3. Although the arc tube 2 is bent into a double spiral shape, the clearance formed between the filament and the inner surfaces of the arc tube 2 on both sides of the filament can be made constant in a front view. In this example, since the pair of caps 18 provided on the arc tube 2 are arranged at point-symmetric positions, the flat lamp 3 and the lamp sockets 5 are formed when the flat lamp 3 is connected to the lamp sockets 5. Replacing the lamp of the fixture main body 1 constituting the main body of the lighting fixture 9, the front shape is substantially rectangular, and each base 18 and each lamp socket 5 can be arranged in a dead space that is an opposite corner of the substantially rectangular shape. The area viewed from the direction facing the opening 28 for use can be made smaller.

  A terminal block 29 is disposed and attached in a recess 38 provided in one side of the instrument body 1 having a flat and thin box shape.

  As described above, the terminal box 29, the lighting block 12 including the ballast 4, the pair of lamp support springs 16, the pair of lamp sockets 5, and the flat lamp 3 are arranged in the appliance body 1 having a thin box shape. In this case, as shown in FIG. 2, the terminal block 29, the lighting block 12 including the ballast 4, the pair of lamp support springs 16, the pair of lamp sockets 5, the lamp support spring 16, and the lamp socket 5 are provided. The flat lamps 3 that are connected and supported are mounted side by side so as not to overlap in the vertical direction (specifically, each member is substantially the same as the surface of the flat lamp 3 (planar light emitting surface)). Therefore, the instrument body 1 can be thinned. Moreover, in this way, the flat lamp 3, the lighting block 12 including the ballast 4, the pair of lamp support springs 16, the pair of lamp sockets 5, and the terminal block 29 are laterally arranged so that they are all located on substantially the same plane. Although the flat lamp 3 is used, the flat lamp 3 is used in spite of being arranged side by side, so that it can be made smaller than an annular lamp, and the size can be reduced accordingly. In the present invention, the arrangement of the interior members in the appliance main body 1 is performed between the attachment portion 7 to the wall surface 6 and the flat lamp arrangement portion 8 in which the flat lamp 3 is arranged on one side of the appliance main body 1. The ballast 4 is arranged so as to have a positional relationship such that the ballast 4 is arranged.

  As described above, the fixture body 1 is mounted in the fixture body 1 with the terminal block 29, the lighting block 12 including the ballast 4, the pair of lamp support springs 16, the pair of lamp sockets 5, and the flat lamp 3 installed therein. A plate 30 is used to attach to the wall surface 6.

  The mounting plate 30 is configured by integrally projecting a fixture fixing plate portion 32 made of a horizontal piece laterally from the upper end of a wall fixing plate portion 31 made of a vertical piece.

  When attaching the instrument body 1 to the wall surface 6, the wall fixing plate portion 31 of the attachment plate 30 is fixed to the wall surface 6 by a fixing tool 33 such as a wood screw in a state where the wall fixing plate portion 31 is in contact with an arbitrary position of the wall surface 6. Thereafter, the appliance fixing plate portion 32 of the attachment plate 30 is inserted from the side opening provided in the attachment portion 7 on one side of the appliance main body 1 having a flat thin box shape, and is inserted into the slit-like attachment opening portion 11. Then, the mounting portion 7 on one side of the instrument body 1 is brought into contact with the wall surface 6 while being superimposed on the block covering portion 15 of the block cover 14. In this state, the fixture fixing plate portion 32 and the block cover portion 15 are fixed by a fixture 34 such as a screw tool. Thereby, the flat thin box-shaped instrument main body 1 thinned in the vertical direction is attached to the wall surface 6 via the attachment plate 30.

  In this case, the fixture fixing plate portion 32 of the attachment plate 30 is inserted from the side opening provided in the attachment portion 7 on one side portion of the appliance main body 1 having a flat thin box shape, and is inserted into the slit-like attachment opening portion 11. Then, by stacking on the block cover portion 15 of the block cover 14, the instrument main body 1 having a thin box shape is stably and temporarily supported by the instrument fixing plate portion 32 having a plate shape made of a horizontal piece, The fixing work by the fixing tool 34 can be easily performed. The fixing work of the fixture 34 is performed by putting a hand through the opening of the main storage portion 13 of the instrument body 1. FIG. 5 shows a state in which the mounting plate 30 and the instrument body 1 are fixed.

  After the fixture body 1 is attached to the wall surface 6 via the attachment plate 30 as described above, the translucent panel 17 is placed in the opening (lamp replacement opening 28) of the main storage portion 13, and the fixture fixing plate portion 32 is placed. The translucent panel 17 is detachably attached to the fixture fixing plate 32 by the attaching means 35 such as a thumbscrew while being in contact with the panel support portion 39, so that the lamp replacement opening 28 is formed on the translucent panel 17. Shield.

  Here, the translucent panel 17 is attached at a position lower than the opening end of the lamp replacement opening 28 of the fixture body 1 (that is, the position pulled inward), so that the translucent panel 17 is located above the lamp replacement opening 28. Further, the length of the side facing the slit-shaped mounting opening 11 of the translucent panel 17 is longer than the length of the mounting opening 11, and it does not protrude outward (upward in the embodiment). Since the knob 36 that protrudes upward is provided at the upper end of the side facing the mounting opening 11 of the translucent panel 17, the translucent panel 17 is placed in the lamp replacement opening 28. Further, the translucent panel 17 is not inserted into the slit-shaped mounting opening 11, and as a result, the translucent panel 17 is placed in the lamp replacement opening so that the knob 36 side is located on the mounting opening 11 side. Put it in 28 In, it can be attached easily by means 35 attached to the translucent panel 17 in a state in which light-transmitting panel 17 to the mounting opening 11 is positioned so as not inserted. The grip portion 36 projects upward from the upper edge portion of the mounting opening 11. When the lamp is replaced, after the mounting by the mounting means 35 is released, the grip portion 36 is gripped with a finger to hold the translucent panel 17. Can be removed.

  The lighting fixture 9 is attached to the wall surface 6 as described above. When the flat lamp 3 is turned on, the light passes through the translucent panel 17 and is irradiated.

By the way, in the present invention, as shown in FIG. 6, the translucent panel 17 has a surface such that the central portion of the translucent panel 17 in the direction along the wall surface 6 polarizes the lamp light forward in the direction opposite to the wall surface 6. and each other by processing has become a central polarization processing unit 17a, also, both the side of the translucent panel 17 in the direction along the wall surface 6 is each other by surface treatment to polarize over the instrument body 1, It is a side polarization processing part 17b.

  Therefore, among the lamp lights passing through the translucent panel 17, the lamp light passing through the central part of the translucent panel 17 is opposite to the wall surface 6 as shown in FIG. 7A through the central polarization processing part 17a. The ceiling surface away from the wall surface 6 or the space near the ceiling surface is illuminated, and is directed upward as shown in FIG. 7C through the side polarization processing portion 17b. The ceiling surface close to the wall surface 6 is irradiated. In this case, the forward polarized light passing through the central polarization processing unit 17a includes the polarization obliquely upward and forward, and the processing for polarization of the central polarization processing unit 17a is performed on the wall surface. In the case where it is processed so as to be polarized obliquely upward and forward in a direction away from 6, the lamp light can be irradiated onto the ceiling surface away from the wall surface 6. Further, when the side polarization processing portion 17b is not provided and this portion is simply a light transmitting portion through which light passes, the lamp light is not polarized on the side portion as shown in FIG. 7B. In FIGS. 7B and 7C, the hatched area indicates a shadow portion.

  In the present invention, as described above, the flat lamp 3, the ballast 4, and the lamp socket 5 are positioned substantially on the same plane as the flat lamp 3 in the flat, thin box-shaped appliance body 1. Thus, the lighting fixture 9 can be thinned. Moreover, since the flat lamp 3 disposed in the instrument body 1 is composed of the arc tube 2 in which the discharge path is swirled in substantially one plane around the central portion of the tube, the flat lamp 3 emits light as a surface including the central portion. Therefore, it is possible to reduce the area of the flat lamp arrangement portion 8 for arranging the flat lamp 3, and to illuminate as described above. Even when the fixture 9 is attached to the wall surface 6, it is possible to reduce the allowance of the lighting fixture 9 (the fixture body 1) from the wall surface 6 as compared with the case where an annular lamp is installed. Moreover, the flat lamp arrangement portion for arranging the mounting portion 7 on the wall surface 6 and the flat lamp 3 while being able to be a lighting fixture 9 that is thin in the vertical direction and has a small allowance from the wall surface 6 as described above. Since the ballast 4 is arranged between the flat lamp 3 and the wall surface 6, the distance between the flat lamp 3 and the wall surface 6 can be separated as much as possible. Can be secured.

  FIG. 8 shows another embodiment of the present invention. In this embodiment, the bottom portion of the flat lamp disposition portion 8 of the block cover 14 is formed as an inclined surface that inclines so as to fall forward as it moves away from the wall surface 6, and is provided at the bottom portion of the flat lamp disposition portion 8 that has become the inclined surface. This is an example in which the flat lamp 3 is attached to the lamp support spring 16 and the lamp socket 5 as described above, and the flat lamp 3 is inclined so as to fall forward as it moves away from the wall surface 6. Since the light emission direction by the light emission plane itself of the lamp 3 is inclined so as to be obliquely upward and frontward as it is away from the wall surface 6, the lamp light irradiated from the flat lamp 3 and passing through the translucent panel 17 is away from the wall surface. As described above, the light is applied to the translucent panel 17 as described above so that the lamp light is polarized forward and polarized forward. Even if not, it is possible to illuminate the space in the vicinity of the ceiling surface away from the ceiling surface or wall 6 away from the wall surface 6. Of course, also in the present embodiment, the central polarization processing portion 17a may be formed in the central portion of the translucent panel 17 and the side polarization processing portions 17b may be formed on both side portions as described above. When such a translucent panel 17 is used, the ceiling surface further away from the wall surface 6 and the space below the ceiling surface further away from the wall surface 6 can be illuminated.

  9 to 11 show another embodiment of the present invention. In the present embodiment, the whole or part of the translucent panel 17 is attached to the instrument body 1 so as to be rotatable.

  In this embodiment, as shown in FIG. 11, the translucent panel 17 is configured by rotatably attaching a translucent disc 41 having undergone polarization processing to a translucent panel body 40 having translucency by a shaft 42. It is. The upper surface portion of the translucent panel main body 40 is provided with a circular paragraph portion 43, and the disk 41 is rotatably overlapped on the paragraph portion 43. The side of the translucent panel main body 40 that faces the mounting opening 11 is a thick portion that protrudes upward from the stage 43, and the upper side of the side facing the mounting opening 11 is above the upper end. A knob 36 is provided so as to project. Further, a hole 44 for inserting a screw tool as the attachment means 35 is provided in the thick part, and after the instrument body 1 is attached to the wall surface 6 via the attachment plate 30 as in the above-described embodiment, The translucent panel 17 is placed in the opening (lamp replacement opening 28) of the main storage part 13, and in contact with the fixture fixing plate part 32 and the panel support part 39, the translucent panel 17 is made transparent by attachment means 35 such as a thumbscrew. By attaching the light panel 17 to the fixture fixing plate part 32 in a detachable manner, the lamp replacement opening 28 is shielded by the light transmitting panel 17.

  Here, when the translucent panel 17 is attached to the attachment plate 30 by the attaching means 35, the end of the translucent panel 17 is correctly positioned without being inserted into the attachment opening 11, and the lamp replacement opening 28 is formed. The translucent panel 17 can be attached to the attachment plate 30 in the closed state as in the above-described embodiment.

  The disk 41 constituting a part of the translucent panel 17 is subjected to surface processing or the like so that the lamp light is polarized in a certain direction. 9 to 11 are examples in which a central polarization processing unit 17a and a side polarization processing unit 17b having different polarization directions are provided. For example, the central polarization processing unit 17a transmits lamp light to the side of the instrument body 1. The surface is processed so as to be polarized in the direction, and the side polarization processing portion 17b is processed so as to be polarized above the instrument body 1.

  Therefore, by rotating the disk 41 which is a part of the translucent panel 17 with respect to the instrument main body 1, the central polarization processing unit 17a is simultaneously irradiated while irradiating the side polarization processing unit 17b so as to be polarized upward. The lamp light from the central polarization processing unit 17a is polarized and irradiated so that the polarization direction of the lamp light is directed in the lateral direction opposite to the wall surface 6, or the central polarization processing unit 17a in the lateral direction along the wall surface 6 is irradiated. It is possible to easily irradiate the target direction, such as by polarizing and irradiating the lamp light according to the above, or by irradiating with the polarized light in an arbitrary lateral direction between the two.

  Of course, in the present invention, the polarization direction of the polarization processing unit is not limited to the above embodiments.
