Description

  The present invention relates to a socket for an LED lamp having an appearance and shape similar to a conventional straight tube fluorescent lamp having caps at both ends.

Recently, in order to renew indoor facilities for the purpose of energy saving, fluorescent lamps for illumination and the like are often replaced with LED lamps with low power consumption and long life.
In the case of indoor facilities that use straight tube fluorescent lamps, if the base of the LED lamp to be replaced can be attached to the socket for the fluorescent lamp, the socket can be used as it is. Can be suppressed.

  As such a prior art, for example, Patent Document 1 below proposes a fluorescent lamp type LED lamp in which an existing fluorescent lamp socket can be mounted and used as it is. Further, Patent Document 2 proposes a lighting fixture that supports both fluorescent lamps and LED lamps. In this case as well, the socket is configured so that a conventional swivel fluorescent lamp can be used as it is.

  By the way, when replacing a conventional swivel type fluorescent lamp represented by a G13 type base with an LED lamp, for example, such a fluorescent lamp is provided with a base having a pair of power supply terminals erected at both ends. Are equivalent in shape and function. On the other hand, a socket corresponding to this fluorescent lamp includes a receiving plate in which an insertion port for inserting these power supply terminals is formed, and a pair of elastic conductive members disposed opposite to the back side of the receiving plate. In this structure, the end face of the base is pressed against the receiving plate and rotated until each of the power supply terminals contacts and is held by the elastic conductive member.

  However, since the light emitting diode element that is the light source of the LED lamp requires a DC power source, the LED lamp is a DC drive type that supplies DC power from the base, or a power source provided on the lamp side by supplying AC power to the base. It becomes either AC drive type that rectifies by the circuit. In the former case, one of the elastic conductive members of the socket needs to be on the plus side and the other must be on the minus side.

  However, when using a DC drive type LED lamp, if the direction of rotation when mounted on the socket is wrong, the polarity of the power supplied to the LED lamp is reversed, which may damage the LED lamp. There is. Therefore, an object of the present invention is to provide a swivel type socket having a novel configuration that does not cause such an operation error.

The present invention proposed to achieve the above object has a main body portion including a pair of conductive members for supplying power to an LED lamp including a pair of power supply terminals, and an insertion port through which the pair of power supply terminals are inserted. And a socket for a straight tube type LED lamp provided with a receiving plate rotatably supported by the main body portion, and the LED lamp is rotated at a receiving position where the pair of power feeding terminals are inserted into the insertion port. To a connection holding position where the pair of conductive members and the pair of power supply terminals are electrically connected to each other.

It said rotation restricting means includes a protruding piece which protrudes in the outer peripheral direction at the periphery of the support plate, two provided on the projecting piece and the abutment positions in the receiving position and the connection holding position definitive to the main body portion You may comprise combining a stopper part.

The conductive member may be an elastic conductive member, and may be deformed by being pushed by the power feeding terminal while the LED lamp is rotating .

  Furthermore, the illumination system according to the present invention is configured using the straight tube type LED lamp socket according to the present invention, and the socket is installed in advance on a ceiling surface or a wall surface, and the straight tube type LED lamp is attached to the socket. It has become.

  Moreover, the lighting fixture by this invention has the structure which combined the straight tube | pipe type LED lamp with the said socket for straight tube | pipe type LED lamps of this invention.

  According to the present invention, the rotation restricting means is provided so that the rotation range when the LED lamp of the receiving plate is mounted is forward or reverse within the range from the receiving position of the pair of power supply terminals to the connection holding position. Since it is configured to allow only rotation, it is possible to reliably prevent an operation error that a rotation direction is wrong when a DC drive type LED lamp is mounted on the socket.

FIG. 1 shows an example of a socket for a straight tube type LED lamp according to the present invention.
Here, (a) is a front view, (b) is a plan view, (c) is a bottom view, (d) is a right side view, and (e) is a rear view, with the receiving plate in the receiving position. Is shown. The left side view is omitted.
FIG. 2 is a front view when the LED lamp is connected and held, and shows a state when the receiving plate is in the holding position.

  The socket 1A incorporates a receiving plate 10 in which an insertion port 13 for inserting a pair of power supply terminals 23 erected on the base of the LED lamp 2A shown in FIG. 4 is formed, and a pair of elastic conductive members 12. The main body 11 is disposed opposite to the back side of the receiving plate 10 and rotatably holds the pair of power supply terminals 23.

The receiving plate 10 is made of, for example, a resin such as polycarbonate, urethane, ABS, and the like. The bearing cylinder portion 11a is supported so as to be rotatable.
The gap portion divided in the radial direction of the receiving plate 10 constitutes an insertion port 13, and when the support shaft 10 a of the receiving plate 10 is fitted into the bearing tube portion 11 a, the bearing tube portion is held by a locking means (not shown). It does not fall off from 11a.

  When the receiving plate 10 is inserted into the insertion port 13 with a pair of power supply terminals 23 protruding from the base of the LED lamp 2A, the end surface of the base of the LED lamp is pressed against the receiving plate 10 and rotated. The rotation range at this time is regulated by a rotation regulating means 14 (described later) provided on the receiving plate 10 and the main body 11.

The rotation restricting means 14 is configured by combining a protruding piece 14 a formed at a proper position on the periphery of the receiving plate 10 and two stopper portions 14 b provided on the main body 11 side.
The rotation range of the receiving plate 10 is set to 0 ° to 90 ° clockwise in the front view (a).
Here, the 0 ° position is a receiving position for inserting the base of the LED lamp through the insertion opening 13, and the 90 ° position is a holding position where the power supply terminal 23 is held by the elastic conductive member 12. The shape of the protruding piece 14a may be, for example, a shape in which two protrusions are provided with a gap around the periphery of the receiving plate 10 other than a continuous arc shape.
Here, the rotation range of the receiving plate 10 is set to 90 ° by restricting the rotation of the arcuate protruding piece 14a having a spread of approximately 90 ° by the stopper portions 14b arranged at intervals of 180 °. However, it is not limited to this.

The elastic conductive member 12 is formed of, for example, a metal plate such as SUP, SUS, PBP, BSP, or SK, and has a substantially J-shaped basic shape as indicated by a broken line in the front view (a).
The tip of the J side on the short side (lower side) is a fixed end, and this portion is fixed inside the main body 11.
The long side (upper side) of the J-shape is bent into a “<” shape, and a recess 12 a is formed as a holding portion in the valley portion of the “<” shape, and both sides thereof serve as guide surfaces.
The elastic conductive member 12 is disposed so as to face each other with the bearing tube portion 11a sandwiched so that the valley portions of the elastic conductive member 12 move away from each other, and the pair of power supply terminals 23 of the lamp 2A is inserted into the insertion port 13 of the receiving plate 10 to When the end surfaces are pressed against each other and rotated, the pair of power supply terminals 23 pass through the gap between the bearing tube portion 11a and the elastic conductive member 12 while sliding while contacting the guide surface of the elastic conductive member 12. It reaches the position and is fitted and held in the recess 12a serving as a holding portion.

The main body 11 is made of the same material as that of the receiving plate 10 and has a plate shape having a kamaboko-shaped outline. An opening 11b having a diameter slightly smaller than that of the receiving plate 10 is provided on the front surface of the main body 11, and a bearing tube 11a projects from the bottom toward the center of the opening 11b.
A notch that is aligned with the insertion opening 13 when the receiving plate 10 is in the receiving position is formed in the upper portion of the main body 11. The bearing tube portion 11 a is provided with two notches that are aligned with the insertion port 13 so that the peripheral wall of the bearing tube portion 11 a does not protrude inside the insertion port 13 when the receiving plate 10 is in the receiving position. . Therefore, if the receiving plate 10 is in the receiving position, the notch in the upper part of the main body 11, the insertion port 13, and the notch in the bearing tube portion 11 a are aligned in a straight line. Can be plugged in.

  The receiving plate 10 covers the edge of the opening 11b of the main body portion 11, and the support shaft 10a is held by the bearing tube portion 11a. Therefore, even if it is pushed backward by the base, it does not move backward with respect to the main body 11. In addition, a guide portion that contacts the inner peripheral surface of the opening 11b is provided on the back side of the receiving plate 10 so as to prevent positional displacement with respect to the opening 11b.

  Further, four small holes 10b are concentrically formed at intervals of 90 ° in the overlapping portion of the receiving plate 10 with the main body portion 11, and the main body portion 11 is concentrically arranged corresponding to the small holes 10b. Two locking claws 11c are formed.

  The locking claw 11c is caught in the small hole 10b when the receiving plate 10 is in the receiving position and when it is in the holding position, and generates resistance against click feeling and displacement.

Fixing claws 15 are provided on both side surfaces of the main body 11 so as to protrude rearward from the rear surface. The front end of the fixed claw 15 is hemispherical, and the intermediate portion has a semicircular cross section with the inner side cut off. A leaf spring 17 having a convex surface on the main body 11 side is passed between the fixing claws 15 so that a gap is not generated by the elastic force.
In addition, a lead wire connection terminal 18 is provided on the bottom surface of the main body 11 and wired to the corresponding elastic conductive member 12. The lead wire connection terminal 18 is preferably a fast connection terminal.

  Although it is assumed that the back side of this socket is fixed to a plate material constituting a lighting fixture or the like, it is necessary to provide a pair of fixing holes corresponding to the fixing claws 15 in the plate material to which the socket is fixed. . The interval between the fixing holes is somewhat narrower than the interval between the fixing claws. In that case, if you move the socket's fixed claw inward and press it firmly against the plate's fixed hole, the fixed claw's tip will pass through the fixed hole. The part is caught by the edge of the fixing hole and cannot be removed, and the socket is fixed to the plate material. Since the socket in this state is held in a state of being slightly lifted from the plate material by the elastic force of the leaf spring 17, it can be moved slightly back and forth.

  The straight tube type LED lamp is provided with a base at both ends, and each base is provided with a power feeding terminal. Here, it is assumed that the LED lamp 2A as a base has a power supply base provided with positive and negative polar terminals for supplying power to the lamp and an earth base provided with a ground terminal for grounding the lamp. That is, the LED lamp 2A is of a direct current drive type. The socket 1A can be used for both a power supply base and a grounding base, but it is particularly preferable to correspond to a power supply base of a DC drive type LED lamp.

  This is because, although the DC power supply has polarity, the socket 1A has a correspondence relationship between the power supply terminal of the LED lamp mounted on the socket 1A and the elastic conductive member 12 of the socket 1A due to the restriction of the rotation range of the receiving plate 10. Because it is established. That is, the rotation restricting means 14 restricts the rotation range of the receiving plate 10 to 90 ° when the LED lamp is mounted. Therefore, when viewed from the front, the power supply terminal 23 located on the upper side in the receiving position is held. The power supply terminal 23 that is always connected to the right elastic conductive member 12 at the position and is lower at the reference position is always connected to the left elastic conductive member 12 at the holding position.

  Further, the socket 1A has one convex portion 16 formed on the receiving plate 10 to prevent erroneous mounting, and a concave portion 24 for fitting the convex portion 16 is provided on the lamp side correspondingly. The shape and structure of the concaves and convexes are not limited, but if there is such a convex part 16, it is possible to prevent erroneous mounting of other types of lamps that do not have a concave part 24 fitted therein. For example, if the base provided with the concave portion 24 corresponding to the convex portion 16 is employed in a DC drive type LED lamp and not employed in an AC drive type LED lamp, the socket 1A can be mounted on the direct current drive type. It becomes only the LED lamp. By providing such a convex portion, a conventional fluorescent lamp cannot be mounted.

  FIG. 3 is an explanatory view showing an example of a ground side socket corresponding to FIG. Constituent elements common to those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.

Although not shown, the elastic conductive member 12 is fixed inside the main body 11.
Unlike the power supply terminals having positive and negative polarities as described above, the socket 1B is not provided with the rotation restricting means 14 and the convex portion 16 is not formed on the receiving plate 10. Also. There is no leaf spring 17 passed between the fixed claws, and when the socket 1B is fixed to the plate material, the rearward projection of the fixed claws is made small so that no gap is formed between the socket 1B and the plate material.

  4A and 4B show DC drive type LED lamps corresponding to the power supply side socket 1A and the earth side socket 1B. FIG. 4B is a front view, FIG. 4A is a right side view, and FIG. 4C is a rear view. is there.

The LED lamp 2A has a semi-cylindrical metal body 20 having a semicircular cross section and a semi-cylindrical translucent cover 21 having a semicircular cross section facing each other to form a straight tube-like appearance as a whole. ing. A substrate (not shown) on which the light emitting element is mounted is fixed to the metal main body 20 so as to face the translucent cover 21 side. The translucent cover 21 has a lens pattern 21a engraved in a stripe shape in the longitudinal direction of the outer wall surface so as to have a light distribution characteristic that illuminates the floor surface well when the LED lamp 2A is disposed at a predetermined height. Has been.
The power supply base 22A is fixed to one end of the LED lamp 2A, and the ground base 22B is fixed to the other end. In FIG. 4, (a) is for feeding, and (c) is for grounding.

  The power supply base 22A has a pair of power supply terminals 23 projecting from its end face, and a concave portion 24 corresponding to the convex portion 16 of the socket 1A is formed. Further, a projection 25 is also provided. This projection 25 is for preventing erroneous insertion into a conventional fluorescent lamp socket, and can be easily removed with fingers or instruments. When the LED lamp 2A is attached to the socket 1A, the protrusion 25 may be removed in advance.

  The grounding cap 22B has substantially the same configuration as the power feeding cap 22A except that the recess 24 is not formed. A pair of power supply terminals 23 is erected on the end face. Again, when the LED lamp 2A is mounted in the socket 1B, the protrusion 25 may be removed in advance.

The socket 1C is assumed to be a power supply socket for an AC drive type LED lamp. Constituent elements common to the example shown in FIG. 1 are assigned the same reference numerals and description thereof is omitted.

  Although not shown, the elastic conductive member 12 is fixed inside the main body 11 as in FIG. Two convex portions 16 are formed on the receiving plate 10. The AC drive type LED lamp employs a base provided with two concave portions 24 corresponding to the two convex portions 16. In this example, the rotation restricting means 14 is not provided. However, since the AC power supply is nonpolar, the correspondence relationship between the power supply terminal of the LED lamp and the elastic conductive member 12 of the socket 1C is not necessarily established. Because it is good.

  6 shows an AC drive type LED lamp corresponding to the socket shown in FIG. 5, wherein (b) is a front view, (a) is a right side view, and (c) is a left side view.

  The LED lamp 2B is a direct current drive type except that the power supply circuit is provided inside and the power supply base has two concave portions 24 corresponding to the two convex portions 16 of the socket 1C formed on the end face. The configuration is substantially the same as that of the LED lamp 2A.
