Is attached to the instrument main body 1 so as to be movable back and forth in the lamp mounting direction, and is inserted into the socket insertion portion 6 of the reflector 3. In this lamp socket 2, a socket cover 2a to which the lamp socket 2 is attached is rotatably attached to a socket base 13 by a shaft 14 so that the lamp socket 2 can be rotated in a horizontal orientation and a downward inclination orientation. It is freely configured. on the other hand,
A pair of elongated holes 15 extending in the forward / backward direction of the lamp socket 2 are formed in the instrument body 1, a washer-attached screw 16 is passed through the elongated hole 15, and is screwed into a screw hole (not shown) of the socket base 13 to insert the socket base 13. Is slidable with respect to the instrument body 1 along the elongated hole 15.

Further, the spring 17 biases the socket base 13 in the backward direction, and a locking portion 18 having a convex portion is provided on the lower surface of the instrument main body 1 so that the socket base 13 is extended in the locking portion. A lock receiving portion 19 is formed in the socket base 13 as a recessed portion that fits into the socket 18. Reference numeral 20 is an engaging protrusion that locks the lamp 5 to the locking portion 21 of the socket base 13.

FIG. 5 shows a state in which the lamp 5 is mounted in the lamp socket 2 and is in a horizontal posture. At this time, the engaging projection 20 is engaged with the engaging portion 21 of the socket base 13 to prevent the lamp 5 from being pulled out. Has become. Also, the lamp socket 2 has a spring 17
As a result, the lamp socket 2 is located on the back side of the reflection plate 3 of the socket insertion portion 6 and is in a state of being retracted into the socket insertion portion 6 when viewed from the opening side of the instrument body 1.

In FIG. 6, the lamp socket 2 is rotated by pulling the tip of the lamp 5 downward from the state of FIG. 5, and at this time, the socket cover 2a abuts on the edge of the socket insertion portion 6, and the socket cover 2a contacts the socket insertion portion. When 6 is pushed, the lamp socket 2 advances against the spring 17 through the slotted screw 16 along the elongated hole 15, and the locking receiving portion 19 is fitted to the locking portion 18. In this state, since the engaging protrusion 20 of the lamp 5 is disengaged from the locking portion 21, the lamp 5 can be pulled out from the lamp socket 2. When the lamp 5 is attached, the lamp 5 is pushed into the lamp socket 2 in the state shown in FIG. Since it is separated from the lock receiving portion 19
Is released from the locking portion 18 by the force of the spring 17, and the spring 17

According to this embodiment, since the lamp socket 2 can be covered with the reflector 3 and the lamp socket 2 does not largely project from the reflector 3, the appearance is improved and the lamp can be replaced when the lamp is replaced. Since the socket 2 can be projected from the socket insertion portion 6, the lamp can be easily replaced. Furthermore, since the visible portion of the lamp socket 2 is reduced, the entire apparatus can be made compact.

In this respect, conventionally, as shown in FIGS. 9 and 10, the lamp socket 2 is fixed to the main body 1 of the fixture,
Moreover, when removing the one-base type lamp, the lamp socket 2 is tilted and then pulled off to remove the lamp socket 2.
It was necessary to project the socket cover 2a from the edge so that the socket cover 2a does not hit the edge of the socket insertion portion 6.
For this reason, the exposed portion of the lamp socket 2 is increased and the appearance is poor. Reference numeral 23 is a lamp support spring.

The second embodiment can also be applied to the one without the shielding rib 7 and the shielding portion 8 described in the first embodiment. The third embodiment of the present invention is shown in FIGS. That is, this lighting fixture relates to the insertion hole 30 for inserting the thumbscrew 32 attached to the fixture body 1 into the reflector 3 made of synthetic resin in the first embodiment. The insertion hole 30 has a plurality of projections 31 protruding inward by forming a large number of arcuate portions on the periphery.
Is provided.

According to this embodiment, since the thumbscrew 32 receives a large number of points on the large number of protrusions 31, the force is dispersed and the individual load of the abutting protrusions 31 is reduced. in this way,
Since the load of the thumbscrew 32 is not concentrated at one place, cracks caused by hitting the thumbscrew 32 can be prevented. conventionally,
As shown in FIGS. 13 to 16, the insertion hole 30 ′ is a mere round hole, and the insertion hole 30 ′ is larger than the diameter of the thumbscrew 32.
Since the hole diameter is large, if the reflector 3 is displaced due to vibration or the like, the threaded portion of the thumbscrew 32 hits the edge of the insertion hole 30 'and the load is likely to concentrate in one place, so that the reflector 3 is not cracked. There was a risk of entering. 33 is a ballast.

A fourth embodiment of the present invention is shown in FIGS. 17 and 18. That is, this lighting fixture relates to the insertion hole 35 of the reflection plate 3 which is inserted into the lamp support spring 23 in the second embodiment. The lamp support spring 23 has a generally U-shaped upper end attached to the lower surface of the appliance body 1 and is formed by arcuate portions 36 and 37 that bulge outward on both sides, and the lower end is folded back outward. The reflector plate 3 is attached to the fixture body 1 by attaching means (not shown).

The protrusions 38 and 39 having different heights slidably contacting the outer surfaces of the arc-shaped portions 36 and 37 of the
An inclined surface 40 that elastically deforms the arc-shaped portions 36 and 37 inward is formed at the tips of the reference numerals 8 and 39. The height of the protrusions 38 and 39 is set so that the protrusion 38 is higher than the protrusion 39.

FIG. 18A shows a state in which the insertion hole 35 of the reflector plate 3 faces the lamp support spring 23, and FIG. 18B shows the reflector plate 3.
Is in a state of approaching the lamp support spring 23 and abutting the inclined surface 40, and (c) is a state in which the reflector 3 is pushed against the lamp support spring 23 and the lamp support spring 23 is pushed into the insertion hole 35. . At this time, the arcuate portion 37 is first bent inward on the inclined surface 40 of the tall protrusion 38, and then the arcuate portion 36 is bent first on the inclined surface 40 of the lower protrusion 39. Bent inward to overlap 37. Therefore, the tips of the lamp support springs 23 do not collide with each other and are stretched, and the lamp support springs 23 can be smoothly inserted into the insertion holes 35 of the reflector 3.

According to this embodiment, the inclined surface 40 allows the lamp support spring 23 to be smoothly inserted into the insertion hole 35 without the reflector 3 being caught by the lamp support spring 23.
Further, since the tip ends of the lamp support springs 23 bend without hitting each other, the insertion hole 35 can be made small. In the case of multiple lamps, the protrusions 38 and 39 of the insertion holes 35 adjacent to each other are arranged in a symmetrical relationship with each other as shown in FIG. 18, so that the higher protrusion 38 hit earlier reaches the lamp support spring 23. Will not be pushed back by the reaction force of.

Conventionally, as shown in FIGS. 19 and 20, when the reflector 3 is attached to the fixture body 1 having the lamp supporting spring 23, only the insertion hole 35 where the lamp supporting spring 23 is present is inserted.
However, the width of the insertion hole 35 is larger than that of the lamp support spring 23.
Was larger than the width of. For this reason, the insertion hole 35 is conspicuous and the appearance is not good, and when the reflector 3 is attached, the lamp support spring 23 may be caught or may not smoothly enter.

A fifth embodiment of the present invention is shown in FIGS. That is, in this luminaire, the lamp support spring 23 in the second embodiment also serves to support the reflection plate 3, and the lamp support spring 23 is attached by the shaft 42 to the mount 4.
3 is rotatably mounted, and the mounting base 43 is mounted on the lower surface of the instrument body 1. In addition, an insertion hole 35, which is an example of an elongated hole through which the lamp support spring 23 and the mounting base 43 can be inserted, is formed in the reflection plate 3 in parallel with the lamp axis direction. Insertion hole 35
Is larger than the width of the lamp support spring 23, but smaller than the width of the lamp. Further, a pair of rotation stopping protrusions 44 are formed on both sides of the insertion hole 35.

22A shows a state in which the lamp support spring 23 and the mounting base 43 are inserted through the insertion hole 35, and FIG. 22B shows a state in which the lamp support spring 23 is rotated 90 degrees. As shown in FIG. 23, the lamp support spring 23
Both sides of the root portion of the base plate 1 pass over one of the rotation stop projections 44 and are positioned between the rotation stop projections 44, and are locked to the edge portion of the insertion hole 35 to fix the reflection plate 3 to the instrument body 1. FIG. 6C shows a state in which the lamp 5 is engaged with the lamp support spring 23, and the insertion hole 35 is hidden by the lamp 5.

According to this embodiment, the insertion hole 3 of the reflection plate 3
Since 5 is small, when the lamp 5 is mounted, it is hidden by the lamp 5 and the insertion hole 35 becomes invisible, resulting in a good appearance. Further, since the reflector 3 can be fixed by the lamp support spring 23, a separate mounting mechanism is unnecessary. Conventionally, FIG. 24 and FIG.
As shown in FIG.
3 has a size penetrating therethrough, and the width of the lamp support spring 2
Since the width was larger than 3, the insertion hole 35 was visible even after the lamp 5 was mounted, and the appearance was poor. The reflector 3 was separately fixed with a decorative screw or the like (not shown).
