Abstract

PROBLEM TO BE SOLVED: To efficiently provide a part for locking its globe. SOLUTION: The luminaire is provided with a light reflector 3 under its luminaire body 2 installed in a ceiling 1 by using an appropriate means and a lamp 4 such as a ring fluorescent lamp under the light reflector 3, covering the under surface of the lamp 4 with a globe 5. On the outer edge of the light reflector 3, locking parts 6 and 7 locking the globe 5 are integrally formed. Also on the outer edge of the locking part 7, a guide section 8 guiding an opening edge 21 of the globe 5 is integrally formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a glove mounting structure for a lighting fixture.

[0002]

2. Description of the Related Art In a lighting fixture in which a reflector is provided on the lower surface of a main body, a lamp is provided on the lower surface of the reflector, and the lower surface of the lamp is covered with gloves, a locking device for locking the glove is provided on the lower surface near the outer periphery of the main body. It was provided with separate screws.

[0003]

However, it should be noted that there is a problem to be solved that the operation of fixing the fastener to the main body with screws is troublesome and the production efficiency is low. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and has as its object to efficiently provide a portion for locking a glove.

[0004]

Means for solving the problems are as described in the claims.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention is described based on matters specific to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

In the illustrated embodiment, a reflector 3 is provided on a lower surface of a main body 2 attached to a ceiling 1 by an appropriate means, a lamp 4 such as an annular fluorescent lamp is provided on a lower surface of the reflector 3, and a lower surface of the lamp 4 is provided. In the lighting fixture covered with the globe 5, a locking portion 6 for locking the globe 5 to the outer peripheral edge of the reflection plate 3
And 7 are integrally formed. A guide portion 8 for guiding the opening edge 21 of the glove 5 is formed integrally with the outer edge of the locking portion 7.

The main body 2 and the reflection plate 3 are made of metal and are fixed to each other with screws or the like, and the globe 5 is made of translucent resin. A lighting circuit section 9 such as a high-frequency inverter is accommodated between the main body 2 and the reflector 3, and an output of the lighting circuit section 9 is supplied to the lamp 4 through a socket 10 exposed on the lower surface of the reflector 3. 4 is a holder 1 fixed to the lower surface of the reflector 3
Supported by 1.

The locking portion 6 includes a first step portion 12 and a first step portion 1.
2, a second step 13 higher than the first step 12, a stopper 14 located at the end of the second step 13, and a small projection 15 located at the entrance of the first step 12. Are formed integrally on the outer peripheral edge of the reflection plate 3. The locking portion 7 is integrally formed on the outer peripheral edge of the reflection plate 3 so as to protrude. At the opening edge 21 of the glove 5, the same number of locked portions 16 as the number of locking portions 6 and 7 are formed.

When the globe 5 is lifted, the opening edge 21 of the globe 5 is guided by the guide portion 8 whose lower part is inclined inward. Next, the glove 5 is rotated clockwise as viewed from below. Then, the locked portion 16 is guided by the upper surface of the first step portion 12 over the small projection 15, and further rotates, enters the upper surface of the second step portion 13, and is brought into contact with the stopper 14 to lock the locked portion. 16 stops and the locked portion 1
6 is locked on the upper surface of the second step portion 13. At this time, the adjacent locked portion 16 is locked on the upper surface of the locking portion 7, and the mounting of the globe 5 is completed. To remove the glove 5, the reverse procedure may be performed, but the locked portion 16 may be prevented from dropping at once.
Comes off the first step portion 12 while contacting the small protrusion 15.
In addition, the locking part 7 and the guide part 8 are not necessarily required. Further, the number of the locked portions 16 may be correspondingly reduced. In this way, the portion for locking the globe 5 could be efficiently provided integrally with the reflector 3.
