Description

The present invention, socket, relates socket cover and a lighting device. More particularly, a socket for the LED lamp used in place of the fluorescent lamp, to socket cover and a lighting device.

  LED (Light Emitting Diode) lamps have lower power consumption and longer life compared to incandescent bulbs and fluorescent lamps. For this reason, LED lamps are spreading as light sources that replace these lamps.

  For example, as a straight tube LED lamp that replaces an existing straight tube fluorescent lamp, a straight tube LED lamp system that is compliant with the Japan Light Bulb Industry Association standard (JEL801: 2010) is on the market. This system employs a base dedicated to a straight tube LED lamp, which is different from a base for a fluorescent lamp (for example, G13). By adopting a base exclusively for straight tube LED lamps, this system prevents erroneous insertion and dropping of the lamps and ensures safety (Non-Patent Document 1).

  On the other hand, there are many needs to replace an LED lamp with an inexpensive and simple modification by utilizing the base of an existing fluorescent lamp. For this reason, for example, a straight tube LED lamp system for attaching an LED lamp using a G13 base is also on the market.

(Embodiment 1)
Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals. FIG. 1 is a diagram for explaining a configuration of a lighting apparatus according to an embodiment. 1A is a bottom view, FIG. 1B is a front view, FIG. 1C is a plan view, and FIG. 1D is a right side view.

  As shown in FIG. 1, the illumination device 1 according to the present embodiment includes a main body 11, an LED lamp 2, and a socket cover 3.

  The main body 11 is essentially the same as the main body using a straight tube fluorescent lamp as a light source. In the present embodiment, the main body 11 is covered with a so-called inverted Fuji-shaped plate member for a straight tube fluorescent lamp whose cross section is perpendicular to the long axis of the lamp. In this inverted Fuji type plate-like member, a reflection plate is arranged on an inclined surface with respect to the central top of the Fuji type. The reflecting plate is made of, for example, a white-coated steel plate.

  Since the main body 11 turns on the LED lamp 2, a circuit such as a power supply unit of an existing straight tube fluorescent lamp is replaced with a power supply unit of the LED lamp. That is, the main body 11 has a power supply unit 12, a power supply terminal block 13, and a signal line terminal block 14 for lighting the LED lamp 2 on the lamp side surface. Since the LED lamp 2 is lit using the main body of the straight tube fluorescent lamp, these parts are attached by modifying the main body of the existing straight tube fluorescent lamp.

  The LED lamp 2 is attached to the main body 11 via a socket cover and an existing socket.

  FIG. 2 is an enlarged cross-sectional view of the socket cover portion of the lighting apparatus according to Embodiment 1. As shown in FIG. 2, the socket cover 3 is disposed on the inclined surface of the inverted Fuji-shaped main body 11, that is, on the reflection plate, and the socket 4 is disposed inside the socket cover 3. The socket cover 3 and the socket 4 are shown in FIGS.

  FIG. 3 is a diagram for explaining a configuration of the socket cover and the socket according to the first embodiment. 3A is a front view, FIG. 3B is a side view thereof, and FIG. 3C is a bottom view thereof. FIG. 4 is a perspective view of the socket cover and the socket according to the first embodiment. 2 and 3 are views when the socket cover 3 is attached to the socket 4. 4A shows the socket cover 3, and FIG. 4B shows the socket 4.

  As shown in FIGS. 2 and 3, the socket cover 3 is configured to cover the socket 4 from the lamp receiver 42 side. That is, the socket cover 3 is formed with a recess 32 that can accommodate the socket 4 and a through hole 31 provided in the recess 32.

  The socket 4 accommodated in the socket cover 3 is the same as the socket for a straight tube fluorescent lamp. That is, the socket 4 is compatible with a socket for a straight tube fluorescent lamp. In this embodiment, a socket for a G13 base for a fluorescent lamp is employed, but a socket for another straight tube type fluorescent lamp may be used. For example, a socket for a base such as G5, R17d, Rx17d, etc. Any one of them may be sufficient. Since these sockets are widely used as sockets for straight tube fluorescent lamps, they are easily available and inexpensive.

  The concave portion 32 is formed so as to be able to accommodate the front side of the socket 4, that is, the surface side on which the lamp receiver 42 and the cap pin connection portion 41 are disposed. In the present embodiment, the recess is formed in substantially the same shape as the structure on the front side of the socket 4. For this reason, when the socket 4 is fitted into the recess 32, the front side of the socket 4 is covered with the socket cover 3.

  The through hole 31 is formed in the recess 32 so that the base pin connection part 41 and the base pin 23 of the socket 4 can be connected. Specifically, the through hole 31 is a portion that accommodates a cap pin connection portion (conductive plate) 41 and a lamp receiver 42 that are the bottom surface of the recess 32 and penetrates the socket cover 3. For this reason, even if the socket 4 is fitted into the socket cover 3, the base pin connection part (conductive plate) 41 and the lamp receiver 42 are not covered by the socket cover 3 and are exposed from the through hole 31.

  The through-hole 31 is formed with a cylindrical surface 31A and a flat surface 31B disposed across the cylinder on the inner surface (the flat surface 31B is convex with respect to the cylindrical surface. ). The cylindrical surface 31A is formed in a cylindrical shape having a diameter that is substantially the same (same or slightly larger) as the base of the straight fluorescent lamp. In other words, it is formed in a shape along the base of the straight tube fluorescent lamp. For this reason, if there is no convex part 31B, the base | tube of the straight tube | pipe type fluorescent lamp of the substantially same magnitude | size as 31 A of cylindrical surfaces can be inserted. Since the cylindrical surface 31A of the present embodiment is formed in a cylindrical shape having substantially the same diameter as the G13 base, the G13 base can be inserted into the cylindrical surface 31A if there is no convex portion 31B. The diameter of the cylindrical surface 31A may be substantially the same as the base of not only the G13 base but also other straight tube fluorescent lamps, for example, the base of G5, R17d, Rx17d, etc.

  The convex portion 31B is formed on the cylindrical surface of the cylindrical surface 31A, and is provided so as to limit the insertion of a cylinder having substantially the same diameter as the cylindrical surface 31A. In detail, the convex part 31B is formed so as to protrude to substantially the same (same or slightly smaller) outer shape as a notch surface 22B described later. That is, the convex portion 31B is formed so that a part of the cylinder of the penetrating part is along a plane cut by a line segment that is a predetermined distance away from the center of the cylinder of the penetrating part, and a part of the cylindrical part of the penetrating part is formed. Is blocked. For this reason, when the base of the straight tube fluorescent lamp is inserted into the through hole 31, it interferes with the base of the straight tube fluorescent lamp. Due to such a function, the convex portion 31B is also referred to as an interference body in the present specification.

  The through-hole 31 supports the LED lamp 2 with the cylindrical surface 31A and the convex portion 31B. The LED lamp 2 is inserted into the through hole 31 of the socket cover 3 and used. Hereinafter, the LED lamp 2 will be described in detail.

  FIG. 5 is a diagram for explaining the configuration of the LED lamp according to the embodiment. 5A is a front view, FIG. 5B is a left side view, and FIG. 5C is a left side view of a modification. As shown in FIG. 5, the LED lamp 2 includes a straight tube-type light emitting unit 21 that uses an LED as a light source, a base 22, and a base pin 23.

  The straight tube light emitting unit 21 is a light emitting unit in which a plurality of LEDs (Light Emitting Diodes) are arranged in a straight tube housing. As shown in FIG. 5, the appearance is almost the same as that of a straight tube fluorescent lamp. For example, the size (diameter and length) of a straight tube type housing is the same as that of a straight tube type fluorescent lamp. In the present embodiment, the straight tube light emitting unit 21 is formed in the same size as a straight tube fluorescent lamp of FHF86 (76W). However, the straight tube light emitting unit 21 may be different depending on the purpose and application of use. It may be formed in the same size as the straight tube fluorescent lamp. For example, it may have the same length as a straight tube fluorescent lamp of a type such as FL20S, FHF32, FL40S. Further, since it is sufficient that the LED lamp 2 can be attached to the socket, the straight tube-type light emitting section 21 may have the same length as the straight tube fluorescent lamp, and the diameter of the straight tube fluorescent lamp is the straight tube fluorescent lamp. It may be smaller than the diameter of the lamp.

  The straight tube light emitting unit 21 has a heat sink that dissipates heat from the LED. The LED is mounted on a substrate, and light is emitted from the side of the substrate on which the LED is mounted (X side shown in FIG. 5), but the heat sink is on the opposite side to the surface on which the LED light is emitted (FIG. 5). Y side). By adopting such an arrangement, it is possible to effectively use light.

  The base 22 is provided at both ends of the straight tube light emitting unit 21. The size and positional relationship of the base with respect to the straight tube-shaped light emitting portion 21 are substantially the same as those of the straight tube fluorescent lamp. For example, the length of R1 shown in FIG. 5 is the same as that of the G13 base for a straight tube fluorescent lamp. Further, the length of the base 22 and the straight tube-shaped light emitting portion 21 (P1 shown in FIG. 5) is 2376 mm, which is the same as the length of the light emitting portion of the G13 base and the straight tube type fluorescent lamp FHF86. This is the length specified by the JIS standard for tube fluorescent lamps. The base 22 has a bottom surface arranged in the same plane as the bottom surface of the base of the straight tube fluorescent lamp. Therefore, the LED lamp 2 is compatible in length with the existing straight tube fluorescent lamp, and the LED lamp 2 Can be attached to the main body 11 of an existing straight tube fluorescent lamp.

  On the other hand, the shape of the base 22 is different from the shape of the straight tube fluorescent lamp. That is, the base 22 is formed in a shape having a cylindrical surface 22A which is a part of a cylindrical outer surface and a cut-out surface 22B having a shape obtained by cutting out a part of the cylindrical surface 22A. In addition, since the base 22 has a shape having a cut-out surface, it is also referred to as a non-cylindrical base in the present specification. On the other hand, a base of a straight tube fluorescent lamp is referred to as a cylindrical base.

  The cylindrical surface 22A is a cylindrical surface having the same diameter as the base of the straight tube fluorescent lamp. In the present embodiment, the diameter of the cylindrical surface 22A is the same as that of the G13 base for a straight tube fluorescent lamp.

  As shown in FIG. 5B, the notch surface 22B is formed in a shape that intersects the bottom surface of the cylindrical surface 22A. Specifically, a part of the cylindrical surface 22A is formed in a shape that is cut by a line segment that is a distance S1 away from the center of the cylinder. The notch surface 22B is provided on the inner side of the circumference of the cylindrical surface 22A, and the surface of the convex portion of the socket cover 3 described above is in a relationship of fitting with the notch surface 22B.

  The cut-out surface 22B may be formed in a shape that intersects the bottom surface of the cylindrical surface of the cylindrical surface 22A, and the shape is not limited to the shape shown in FIG. For example, the notch surface 22B may be formed in the shape shown in FIG. 5C in order to dispose fixing means (screws) for fixing the straight tube light emitting unit 21. That is, the cut-out surface 22B is composed of a surface formed along a surface cut by a line segment separated from the center of the cylinder by a distance S1, and a surface formed so as to cut out both ends of the surface. May be. Thus, the notch surface 22B is good to be formed in the shape which cross | intersects the cylindrical bottom face of 22 A of cylindrical surfaces.

  The cut-out surface 22B is preferably formed asymmetrically with respect to an axis orthogonal to the light emission axis of the light emission surface of the LED lamp 2 when viewed in the long axis direction of the LED lamp. In the present embodiment, the notch surface 22B is disposed substantially symmetrically with respect to the light emission axis. However, by forming the notch surface 22B asymmetric with respect to the light emission axis, the position of the notch surface 22B is determined. This makes it possible to easily identify the light emitting surface of the LED. That is, when the light emission axes of the cut-out surface 22B and the light emitting surface are symmetric, the LED lamp 2 may be erroneously attached upside down (the light emitting surface is the upper surface on which the reflector of the main body is located, and the heat sink described above is connected to the lower surface). However, it is possible to prevent such erroneous insertion of the LED lamp by forming the notch surface 22B asymmetrically with respect to the light emitting axis.

  The base pin 21 is provided on the end surface of the base 22 and is formed so as to be connectable to a socket of a straight tube type lighting device. The metal pins extending from both ends of the LED lamp are electrically connected to the power supply unit 12 through sockets that hold both ends of the lamp.

  The base pin 21 is formed so as to be compatible with the base pin of the straight tube fluorescent lamp. In the present embodiment, since the socket is a G13 base socket for a fluorescent lamp, the base pin 21 has the same shape and size as the base pin of the G13 base. For example, the pin length Q and the pin interval T shown in FIG. 5 conform to the JIS standard dimensions of the G13 base. Thus, the base pin 21 of the present embodiment is compatible with the base pin of the G13 base.

  FIG. 6 is a diagram for explaining a connection relationship among the LED lamp, the socket cover, and the socket. As shown in FIG. 6, the notch surface 22 </ b> B of the LED lamp 2 is formed at a position corresponding to the convex portion 31 </ b> B of the through hole 31, and the outer shapes thereof are substantially the same. That is, the notch surface 22B of the LED lamp 2 is in a relationship of fitting with a part of the surface of the convex portion 31B of the through hole 31. For this reason, the base 22 of the LED lamp 2 formed in a shape having the cylindrical surface 22 </ b> A and the notch surface 22 </ b> B can be inserted into the through hole 31. The base pin 21 at the tip of the base 22 inserted into the through hole 31 is connected to the base pin connection part 41 in the lamp receiver 42 of the socket 4 through the socket cover 3. Since the lamp receiver 42 is fixed to the socket body via a spring, the LED lamp 2 is held between the sockets 4 at both ends by the repulsive force. With such a structure, the LED lamp 2 is attached to the socket 4.

  On the other hand, the base of the straight tube fluorescent lamp (for example, the G13 base) has a circular cross section and is a complete cylinder. Therefore, the base of the straight tube fluorescent lamp has the convex portion 31B of the through hole 31. It is not in a mating relationship with the surface. For this reason, the base of the straight tube fluorescent lamp cannot be inserted into the through hole 31, and the straight tube fluorescent lamp cannot be attached to the socket 4. As described above, the socket cover 3 having the protrusions formed in the through holes 31 restricts the insertion of the base of the straight tube fluorescent lamp, prevents the straight tube fluorescent lamp from being erroneously inserted into the socket 4, and is safe. Secure.

(Embodiment 2)
In Embodiment 1, the convex part 31B of the through-hole 31 formed in the socket cover 3 has substantially the same shape as the cutout surface 22B of the LED lamp 2, and a part of the convex part 31B and the cutout surface 22B. In the above description, the LED lamp 2 cannot be rotated about the long axis, but a convex portion 31B that allows the LED lamp 2 to rotate about the long axis may be formed.

  For example, when the cap of the LED lamp 2 is inserted into the through-hole, the convex portion of the through-hole is fitted to the first surface that can be fitted to the cut-out surface of the LED lamp 2 and the cut-out surface. The LED lamp 2 may be formed in a shape having a second surface that can be fitted to the cut-out surface of the LED lamp 2 when the LED lamp 2 rotates from the position by a predetermined angle around the major axis.

  FIG. 7 is a diagram for explaining the configuration of the socket cover according to the second embodiment. The socket covered with the socket cover 30 shown in FIG. 7 is a socket in which the lamp receiver 44 can rotate at a predetermined angle. This socket is a socket (G13 base) for an existing straight tube fluorescent lamp. The lamp base 44 is pressed against the base pin connection portion 43 and the lamp receiver 44 is rotated by a predetermined angle, so that the lamp is rotated. This type of socket is attached to the socket.

  The socket cover 30 includes a through hole 36, and the through hole 36 is formed with a cylindrical surface 36A and a triangular convex portion 36B provided on the surface of the cylindrical surface 36A.

  The convex portion 36B is a region surrounded by both a line segment extending in the horizontal direction at a predetermined distance from the center of the cylinder of the through hole 36 and a line segment extending in the vertical direction at a predetermined distance from the center. It is formed to occupy. In other words, the convex portion 36B is formed to have a substantially triangular cross section surrounded by the above-described line segment and having the base of the circular arc of the cylindrical surface 36A.

  As shown in FIG. 7B, when the base 22 is oriented so that the base pin connection portion 41 is vertically aligned, the notch surface 22B of the LED lamp 2 is in contact with one side of the substantially triangular shape of the convex portion 36B. That is, when the base of the LED lamp 2 is inserted into the through hole, one side of the substantially triangular portion of the convex portion 36 </ b> B fits into the cut-out surface of the LED lamp 2. For this reason, the base 22 of the LED lamp 2 can be inserted into the through hole 36 of the socket cover 30.

  In this state, the base 22 of the LED lamp 2 is inserted into the through hole 36 of the socket cover 30, the base pin is pressed against the base pin connection part 43, and the base 22 is oriented so that the base pin connection part 41 is arranged side by side. The LED lamp 2 is rotated around the long axis. (See FIG. 7C).

  When the base 22 is oriented so that the base pin connection portion 41 is aligned on the left and right, the cut-out surface 22B of the LED lamp 2 is in contact with the other side of the substantially triangular portion of the convex portion 36B (see FIG. 7C). When the base of the LED lamp 2 is rotated through the through hole, the other side of the substantially triangular portion of the convex portion 36B is fitted into the cut-out surface of the LED lamp 2. In this way, the lamp receiver 44 rotates approximately 90 degrees, and the LED lamp 2 is attached to the socket.

  As described above, the convex portion 36 </ b> B may be formed smaller than the notch surface 22 </ b> B of the base 22 so that the base 22 of the LED lamp 2 can rotate by a predetermined angle within the through hole 36. Also in this embodiment, insertion of the base of the straight tube fluorescent lamp is restricted, and erroneous insertion of the straight tube fluorescent lamp into the socket 4 is prevented.

(Embodiment 3)
Although the example of the G13 base has been described in the first embodiment, the present invention can also be applied to the base of another straight tube fluorescent lamp, for example, the Rx17d base shown in FIG.

  FIG. 8 is a diagram for explaining the configuration of the LED lamp according to the third embodiment. FIG. 8A is a front view, and FIG. 8B is a left side view. The LED lamp shown in FIG. 8 includes a straight tube-type light emitting portion 26, a base 27 and a base pin 28 that conform to the standard of the Rx17d base.

  The base 27 is formed such that a cylindrical surface 27A having a diameter conforming to the standard of the Rx17d base of the straight tube fluorescent lamp and a part of the cylindrical surface 27A are cut by a line segment separated from the center of the cylinder by a distance S2. And a notch surface 27B.

  Also in the present embodiment, as in the first embodiment, the notch surface 27B of the LED lamp is in a relationship of fitting with the convex portion 31B of the socket cover 3, and the base of the straight tube fluorescent lamp is a through hole. It is not in the relationship which fits 31 convex part 31B. Therefore, also in the present embodiment, the socket cover 3 restricts the insertion of the base of the straight tube fluorescent lamp, and prevents the straight tube fluorescent lamp from being erroneously inserted into the socket 4.

(Other embodiments)
In the first to third embodiments, the cut-out surface 27B of the LED lamp has a shape cut out in a direction substantially perpendicular to the bottom surface of the base, but the present invention is not limited to the above-described embodiment and the like. Absent. FIG. 9 is a front view for explaining a configuration of a modified example of the LED lamp. 9 (A), (B), and (C) show different types of caps, FIG. 9 (A) shows the cap according to Embodiment 1, and FIGS. 9 (B) and (C) A base according to another embodiment. In FIG. 9, the dotted line E indicates the position of the side surface of the base of the straight tube fluorescent lamp, the dotted line B indicates the position of the bottom surface of the base of the straight tube fluorescent lamp, and the dotted line C indicates the position of the notch surface of the base of the LED lamp. , Respectively. The dotted line E represents the position of the side surface of the base when the straight tube fluorescent lamps are arranged at the same position.

  As shown in FIG. 9, the base 22 of the LED lamp according to the present embodiment may have an outer shape in which a notch surface that intersects the bottom surface of the base is formed. For example, in the form of FIG. 9B, the base 22 is formed in an outer shape that is cut out by a surface extending in a direction substantially perpendicular to the bottom surface of the base and a surface parallel to the bottom surface from the side surface of the base (see FIG. 9B). 9 (B), see dotted line C).

  Further, in the form of FIG. 9C, the base 22 is formed in an outer shape cut out by a surface extending from the bottom surface to the side surface of the base, that is, a surface extending obliquely from the bottom surface (see FIG. 9C). (See dotted line C).

  9B and 9C, a notch surface is provided between the bottom surface of the base 22 of the LED lamp and the top surface on the LED lamp side. That is, when the side surface from the bottom surface to the top surface of the base 22 is R, R and the cut-out surface intersect.

  On the other hand, in the form shown in FIG. 9A, the notch surface extends in a direction substantially perpendicular to the bottom surface of the base 22 of the LED lamp, and the above R and the notch surface do not intersect.

  As described above, the embodiment of the present invention only needs to have an outer shape in which at least the notch surface that intersects the bottom surface of the base of the base 22 is formed. In order for the convex part of the through hole of the socket cover to limit the insertion of the base of the straight tube fluorescent lamp, it is sufficient that at least a notch surface is formed on the insertion side of the lamp, that is, the bottom side of the base.

  FIG. 9 shows the case where the diameter of the cylindrical surface of the base of the LED lamp is the same as that of the straight fluorescent lamp. However, the notch surface has a base of the straight fluorescent lamp with respect to the base pin. The diameter of the base of the LED lamp is not limited to the size of the base of the straight fluorescent lamp. In order for the convex part of the through hole of the socket cover to restrict the insertion of the base of the straight tube fluorescent lamp, the base of the LED lamp has a diameter almost equal to or larger than the cylinder of the base of the straight tube fluorescent lamp. The shape of the base is not limited to the cylinder as long as it is larger than the size.

  FIG. 10 is a side view for explaining the configuration of a base according to a modification of the LED lamp. The base of the LED lamp shown in FIG. 10 (B) is a cylinder larger than the diameter of the base of the straight tube fluorescent lamp (U <V1, see FIG. 10 (B)). It is formed at a position separated by a distance S. Since the line segment at a distance S away from the center intersects the bottom surface of the base of the straight tube fluorescent lamp, the straight tube fluorescent lamp is inserted into the through hole of the socket cover in which the convex portion corresponding to this form is formed. Even when trying to insert the base, insertion of the base of the straight tube fluorescent lamp is restricted by the convex portion of the through hole of the socket cover.

  FIG. 10C shows a base of an LED lamp formed in an outer shape of a rectangular section (outside is a rectangular parallelepiped) having a side larger than the diameter of the base of the straight tube fluorescent lamp (U <V2). , U <V3, see FIG. 10 (C)). In the base, similarly to the embodiment shown in FIG. 10B, a notch surface that intersects the bottom surface of the base of the straight fluorescent lamp is formed at a position away from the center by a distance S. For this reason, similarly to the embodiment shown in FIG. 10 (B), even if an attempt is made to insert the base of the straight fluorescent lamp into the through hole of the socket cover in which the convex portion corresponding to this embodiment is formed, the penetration of the socket cover Due to the convex portion of the hole, insertion of the base of the straight tube fluorescent lamp is restricted.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, in the above embodiment, the socket and the socket cover are separate, but the socket and the socket cover may be integrated. The socket and the socket cover may be joined and integrated, or the socket and the socket cover may be formed of resin and integrated. For example, an insertion hole into which a base of an LED lamp can be inserted may be formed, and a base pin connection portion may be disposed at the bottom thereof. In this case, the insertion hole functions as a socket arranged in the through hole and the recess of the socket cover described above.

  In the above embodiment, a through hole is formed in the socket cover, and an LED lamp is inserted into the through hole. However, the socket cover covers the socket in a bowl shape, and an LED is formed in the flange part. A form in which a lamp is inserted may be used. An example is shown in FIG. FIG. 11 is a perspective view for explaining a configuration of a modified example of the socket cover.

  As shown in FIG. 11, the socket cover according to the modified example includes a socket accommodating portion 33 that can accommodate a socket (for example, G13) that fits the cylindrical base of the straight tube fluorescent lamp, and a case where the socket is accommodated. A convex portion 31B (interference body) disposed on the front surface side is formed. The socket accommodating portion 33 is configured such that the flange 34 covers the socket. In this case, if the convex portion has a surface corresponding to the notch surface of the LED lamp, the LED lamp can be connected to the base pin connecting portion, but the straight tube fluorescent lamp cannot be connected because the convex portion interferes. As described above, a through hole may not be formed in the socket cover, and a hook (others, for example, a wall) that accommodates the socket may be formed instead.

  Further, the hook-shaped socket cover may be integrated with the socket. For example, a socket provided with a base pin connection part and the above-mentioned convex part (interference body) may be used. Moreover, what integrated the socket-shaped socket cover with the socket may comprise an illuminating device.

  Various embodiments and modifications can be made to the present invention without departing from the broad spirit and scope of the present invention. The above-described embodiments are for explaining the present invention, and do not limit the scope of the present invention.
