Description

  The present invention relates to a lamp device that is detachably fixed to a fixture body and a lighting fixture using the same.

  Conventionally, it has been proposed to use a lamp device using an LED as a downlight fixture. Further, a GX53 type or GH76P type base part or the like is known as a base part to be mounted by rotating the lamp device. This lamp device has a flat shape, and has a structure in which a lamp pin matching the GX53 type or the like is provided on the upper surface side, and a planar light source composed of an LED or the like is disposed on the lower surface side.

  In general, the lamp device described above is rotated to hold the lamp pin with the insulator of the socket, but various structures have been proposed in consideration of safety when the lamp device is mounted on the fixture body. (For example, refer to Patent Documents 1 and 2). Patent Document 1 discloses a lighting fixture in which a hook is provided on a side wall of a lamp device, and the lamp device is detachably attached to the fixture main body by hooking the hook on a socket on the fixture main body side. When the lamp device is removed from the fixture body, a finger is inserted from the side wall of the lamp device to release the hooked state. Patent Document 2 proposes a lamp device having a structure in which a convex portion is provided on the irradiation surface side and a rotating operation is assisted by hooking a finger or the like.

Chinese Patent Application No. 2012010093692 (paragraphs 0028 and 0037) JP2013-30414A (paragraph 0028)

  However, since the lock release mechanism of Patent Document 1 releases the locked state by operating the side surface of the lamp device, it is necessary to insert a finger between the fixture body on the lighting fixture side and the lamp device. A gap is required and the lighting fixture becomes large.

  In addition, as the amount of light in the lamp device increases, a lamp body of the lamp device requires a heat sink that performs heat dissipation processed with aluminum or the like. For this reason, there exists a tendency for a weight to increase compared with the lamp apparatus using a fluorescent lamp. On the other hand, there is a possibility that the lamp device may rotate unintentionally and fall from the socket due to an external factor such as an earthquake or a bad mounting of the lamp, and the risk increases especially when the weight of the lamp device increases. Therefore, when only the anti-slip is provided as in Patent Document 2, when the lamp device is released from the socket, the heavy weight of the lamp device is applied to the fingertip and becomes unstable. There may be dangers when working.

  The present invention has been made to solve the above-described problems, and provides a lamp device capable of suppressing an increase in size of a lighting fixture and improving safety and convenience, and a lighting fixture using the same. It is intended to provide.

  According to the lamp device of the present invention and the lighting fixture using the same, the slide of the locking member provided on the side wall side of the lamp body is operated by operating the operation unit provided on the irradiation cover side that emits light. Therefore, since the attachment / detachment structure to the fixture body on the side wall side can be operated on the light emitting surface side, the increase in size of the lighting fixture can be suppressed. Furthermore, by providing an attachment / detachment structure with a locking member in addition to the attachment / detachment structure at the base part with respect to the instrument body, it is possible to prevent the lamp device from unexpectedly dropping when the base part is removed from the instrument body. Safety and convenience can be improved.

It has been. In particular, the plurality of locking members 20 are provided at positions that are rotationally symmetric with respect to the center of the lamp body 11. For example, the pair of locking members 20 are provided at positions that are symmetric with respect to the center. Thereby, the lamp device 10 can be stably held on the fixture body 2 by the plurality of locking members 20.

  The locking member 20 is provided so as to be slidable outwardly in the guide rail 11A formed in a concave shape from the side wall 11S of the lamp body 11 inwardly. Specifically, a guide rail 11A formed in a concave shape along the radial direction is formed on the other surface side of the heat sink 12, and the locking member 20 is placed on the guide rail 11A. The locking member 20 moves in the radial direction along the guide rail 11A while being held by the heat sink 12 on the bottom surface of the guide rail 11A.

  The locking member 20 includes a connecting portion 21 connected to the operation portion 30 and a protrusion 22 provided on one end side of the connecting portion 21 and extending outward of the side wall 11S in the lamp main body 11. . The connection part 21 is provided with the 1st inclined surface 21b provided in the both ends of the convex part 21a formed in the rectangular shape, for example, and the convex part 21a. The other end side of the connecting portion 21 is biased by the spring 40 in a direction toward the outside of the side wall 11S. The protrusion 22 protrudes outward from the side wall 11S of the lamp body 11 and is locked in the locking groove 2B of the fixture body 2 and has a chamfered portion that is curved at the tip. Note that a step is formed at the base portion of the protrusion 22, and the locking member 20 is prevented from falling off the side wall 11 </ b> S when the step hits the irradiation cover 15.

  On the other hand, the operation unit 30 is provided on the irradiation cover 15 and operates the slide of the plurality of locking members 20, and is composed of, for example, a push button.

The convex portion 21a of the connecting portion 21 of the locking member 20 is fitted into the concave portion 31 of the operating portion 30, and the first inclined surface 21b of the locking member 20 and the second inclined surface 32 of the operating portion 30 are in contact with each other. .

  9 is a perspective view showing a state when the operation unit is pressed in the lamp device of FIG. 4, and FIG. 10 is a schematic view showing states of the locking member and the operation unit in the lamp device of FIG. As shown in FIGS. 7 to 10, when the operation unit 30 is pushed, force is applied from the second inclined surface 32 to the first inclined surface 21b. Then, the locking member 20 moves inward of the lamp body 11 (in the direction of the arrow α1 in FIG. 8) along the guide rail 11A against the bias of the spring 40.

  As shown in FIGS. 7 to 10, the locking member 20 protrudes from the side wall 11 </ b> S of the lamp body 11 by a distance ΔL due to the bias of the spring 40 when the operation unit 30 is not pushed. Then, as shown in FIG. 5, the outer shape of the lamp device 10 has a size of a distance R1 + 2ΔL obtained by adding the length of the protruding distance 2ΔL of the pair of locking members 20 to the outer diameter R1 of the lamp body 11. ing. On the other hand, the inner diameter R0 of the hollow portion 2A of the instrument body 2 is formed to be smaller than the distance R1 + 2ΔL. Therefore, when the lamp device 10 is mounted on the fixture body 2, the protrusion 22 is inserted while being pressed against the wall surface of the hollow portion 2 </ b> A. Then, when the protrusion 22 is positioned at a position where it hits the locking groove 2B, it slides outward by the bias of the spring 40, and the locking member 20 is locked in the locking groove 2B.

  On the other hand, when the operating member 30 is pushed while the locking member 20 is locked in the locking groove 2B, the locking member 20 moves inward of the lamp body 11, and the outer diameter of the lamp device 10 is It becomes smaller than the outer diameter of the hollow part 2A of the instrument body 2. Then, the locking state in the locking groove 2B of the locking member 20 is released, and the lamp device 10 can be removed from the fixture body 2 (see FIG. 9).

  Next, the mounting operation and the detaching operation of the lamp device 10 will be described with reference to FIGS. First, when an operator attaches the lamp device 10 to the instrument main body 2, the protrusion 22 is inserted into the hollow portion 2A of the instrument main body 2 in a state of protruding from the side wall 11S. At this time, the chamfered portion at the tip of the protruding portion 22 hits the edge of the hollow portion 2A, and a force is applied in the radial direction from the edge of the hollow portion 2A to the protruding portion 22. Then, the protrusion 22 slides along the guide rail 11A, and the lamp device 10 is inserted into the hollow portion 2A while the protrusion 22 is accommodated.

  Thereafter, when the lamp pin 14 of the lamp device 10 is mounted on the socket 4, the protrusion 22 is simultaneously positioned at a position facing the locking groove 2B. Then, the force pushed by the protrusion 22 is lost, and the locking member 20 extends outward from the side surface by the spring 40 and is locked in the locking groove 2B. In other words, the plurality of protrusions 22 are locked in the locking grooves 2 </ b> B, thereby supporting the weight of the lamp device 10. In this state, the operator rotates the lamp device 10 to electrically connect the socket 4 and the lamp pin 14.

  On the other hand, when removing the lamp device 10, the operator rotates the lamp device 10 to release the connection between the socket 4 and the lamp pin 14. At this time, the locking member 20 of the lamp device 10 is in a state of being caught in the locking groove 2B on the instrument body 2 side. Therefore, even when the lamp pin 14 is detached from the socket 4, the lamp device 10 is held by the fixture body 2 and prevents the lamp device 10 from dropping unexpectedly. Thereafter, when the operator presses the operation unit 30, the protrusion 22 of the locking member 20 connected to the operation unit 30 slides into the lamp body 11. Then, the locking state between the protrusion 22 and the locking groove 2 </ b> B of the instrument body 2 is released, and the lamp device 10 becomes removable from the instrument body 2.

  In this way, by operating the slide of the locking member 20 provided on the side wall 11S of the lamp main body 11 by operating the operation unit 30 provided on the irradiation cover 15 side of the lamp main body 11, the instrument main body 2 on the side wall 11S is operated. Since the attachment / detachment structure can be operated on the irradiation cover 15 side, an increase in the size of the lighting fixture 1 can be suppressed. That is, since it is not necessary to release the locked state by directly operating the side wall 11S of the lamp device with a finger as in the prior art, there is no need to provide a gap for inserting the finger, and the luminaire 1 can be downsized. can do.

  In addition to the mounting structure of the socket 4 and the lamp pin 14, by providing a mounting structure with the locking member 20 and the locking groove 2 </ b> B, the lamp device 10 can be unexpectedly removed when the base 13 is removed from the instrument body 2. Since it can prevent falling, safety and convenience can be improved. In other words, in the conventional lamp device, when the lamp device is released from the socket, the weight is applied to the fingertip, so that the holding state of the lamp device becomes unstable, which may cause danger in work at a high place. Further, when the lighting apparatus is thinned and lit for the purpose of energy saving or the like, it is necessary to remove the lamp device because the socket cannot hold the lamp while the lamp device is not lit, which is troublesome. On the other hand, in the lamp device 10 of FIG. 1, even if the connection state between the cap 13 and the socket 4 is released, the lamp device 10 is not limited as long as the locking state between the locking groove 2B and the locking member 20 is not released. Since the apparatus 10 does not fall out of the instrument body 2, safety and convenience can be improved.

  Embodiments of the present invention are not limited to the above embodiments. For example, in the above embodiment, the case where the lamp main body 11 has a structure in which the base portion 13 is attached to the through hole 12a of the heat sink 12 is illustrated, but the present invention is not limited to this, and for example, the base portion 13 is provided on the heat sink 12. Various known structures such as a fixed structure can be employed.

  Moreover, in the said embodiment, although illustrated about the case where the two locking members 20 are provided, three or more may be provided. Furthermore, although the case where the operation unit 30 is provided for each of the plurality of locking members 20 is illustrated, one operation unit 30 is connected to the plurality of locking members 20, and the one operation unit 30 is A plurality of locking members 20 may be housed inside the lamp body 11 when pressed.

It is provided and the convex part may be provided in the operation part 30 side. Furthermore, if the locking member 20 slides by operation of the operation part 30, it will not be limited to the said structure, A various well-known machine element can be used. Furthermore, although the operation part 30 illustrated about the case where it consists of a push button, what is necessary is just to be able to operate the sliding movement of the locking member 20, and may consist of a pull button etc. Moreover, although the case where the locking groove 2B of the instrument body 2 is formed of a through hole is illustrated, the protrusion 22 protrudes from the side wall 11S regardless of the configuration as long as the locking member 20 is locked. As long as it is locked when it is done.
