Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recessed lighting fixture, particularly an angle type recessed lighting fixture whose main body is made of a metal plate with side openings.

For recessed lighting fixtures, if the bottom opening is covered with accessories such as globes or panels, the accessories must be removable in order to be able to replace the lamp from inside the room, and in particular, reflectors must be installed to control light distribution. When doing so, it is expected that the structure will become even more complex, increasing costs and deteriorating workability.

On the other hand, as a structure for attaching accessories to conventionally known recessed lighting equipment, for example,
As shown in Japanese Patent No. 53-86880, the spring receiving piece 14 is directly cut out from the side plate 3 and the V-shaped spring 37 is locked to support the decorative frame 31 on which the cover 41 is placed. As shown in Japanese Patent No. 29758, a substantially diamond-shaped mounting spring 20 is engaged with a guide fitting 26 fixed to the inner wall surface of the instrument main body 5 to support the supporting frame 11 on which the cover 9 is placed. As shown in Japanese Patent No. 51-20621, a spring receiver 6 having an L-shaped cross section
are fixed to the inner surfaces of both side walls of the main body 1 to form a V-shaped spring 13.
There is a device that supports the frame 8 on which the lid 17 is placed by locking the spring support piece 14, but in the one shown in Japanese Utility Model Application Publication No. 53-86880, after the spring receiving piece 14 is cut and raised, The strength of the side plate portion 3 is reduced due to the hole, and although there is no risk of a reduction in strength in the structure shown in Japanese Utility Model Publication No. 51-20621, the cost increases because the spring receiver 6 is required as a separate component. At the same time, the spring 13 is locked due to the width of the spring receiver 6.
There were problems such as the possibility that the position of the machine might move.

Therefore, the inventor of the present invention first proposed Utility Model Application No. 56-74063 as a mounting structure for a mounting bracket for mounting accessories in an angle-type recessed lighting fixture whose main body is made up of a metal plate with side openings. However, in this invention, the reflector is simply attached to the top plate removably by a spring, and the positioning and fixing to the lighting fixture body is not sufficient, making it inconvenient to control the specified light distribution. It was hot.

The present invention has been made in view of the above background, and an object of the present invention is to easily and firmly mount a mounting bracket for attaching an accessory of a recessed lighting device and a reflector.

The present invention will be explained below based on the embodiments shown in FIGS. 1 to 3.

Reference numeral 1 indicates an angle-type lighting fixture body formed in a gate shape with a metal plate, and an upper plate-shaped top plate portion 1a.
Electrical parts for lighting such as a socket for attaching a lamp are attached to the lamp body 1, and two gutter-shaped legs 1b having a substantially U-shaped cross section are installed in centrally symmetrical positions on the side surface of the top plate 1a. Both gutter side walls are made to protrude in the direction and are riveted at the upper ends, and an annular frame 1c having an L-shaped cross section is riveted to the lower end of the leg portion 1b facing the top plate portion 1a. Further, both gutter side walls of the leg portion 1b are provided with slits 1d facing each other at the lower part thereof, and the locking piece 1
It becomes e. Reference numeral 2 denotes a reflecting plate formed into a substantially megaphone shape by drawing with the inner surface as a reflective surface, and an outer flange 2a is formed on the outer periphery of the opening end on the indoor side, and a mountain-shaped outer flange 2a is formed on the outer periphery of the opening end on the socket side. A spring engaging portion 2b is formed that protrudes toward. The reflector 2 is
The two reflector mounting springs 3 attached to the top plate part 1a of the lighting fixture body 1 are engaged with the lower surface of the spring engaging part 2b and pulled upward, and the outer flange 2a of the reflector plate 2 is pulled up.
is caught on a locking portion 1f formed in a notch shape near the lower end of the leg portion 1b of the lighting device main body 1, and is fixed to the lighting device main body 1. A globe 5 attached to a mounting bracket 4 having a light-transmitting opening has an open top surface, and two mounting springs 6 are attached to the mounting bracket 4 at centrally symmetrical positions so as to be elastically deformable. The mounting spring 6 has a shape in which two doglegged arms 6a are connected at a substantially U-shaped portion, and its maximum width is wider than the width between both gutter side walls of the leg portion 1b of the lighting fixture body 1. ,
It is fixed to the mounting bracket 4 at the tips of the two arms 6a. The lighting fixture body 1 is fixed to the back surface of the ceiling by means of a fixture 7 which is vertically movable and fixedly protruded outwardly from the leg portion and is inserted into a mounting hole in the ceiling surface. The mounting spring 6 is bent so that the width is narrower than the distance between the two locking pieces 1e of the leg part 1b, and the doglegged bent part is inserted into the slit 1d.
The globe 5 comes into contact with the lower end and attempts to return to its free state, and its elastic return force causes the globe 5 to be pulled upward and attached to the lighting fixture body 1.

When installing this recessed lighting fixture, the reflector plate 2 is attached to the lighting fixture body 1 which is recessed into the ceiling surface.
When inserted, the reflector mounting spring 3 slides on the upper surface of the spring engaging part 2b of the reflector 2 and expands outward, and the reflector attaching spring 3 climbs over the top of the spring engaging part 2b and engages with the lower surface of the spring engaging part 2b, causing reflection. The plate 2 is pulled upward, and the outer flange 2a of the reflecting plate 2 engages with the locking part 1f of the lighting fixture body 1, and the reflecting plate 2 is pulled up into the lighting fixture body 1.
Fixed. Accessories such as gloves 5, etc.
With the reflector 2 attached and fixed to the lighting fixture main body 1, the arm 6a of the mounting spring 6 is fitted into the slit 1d of the lighting fixture main body 1 to be mounted. In addition, when replacing the lamp, the reflector 2 and the globe 5 are attached to the lighting fixture body 1 separately, so the globe 5
It is easy to work by removing just that part.

As described above, in the recessed lighting device according to the present invention, the reflector plate having the outer flange at the lower end opening is biased upward by the reflector mounting spring provided on the lighting device body, and is installed near the lower end of the leg. It is attached to the lighting fixture body by locking the outer flange to the locking part, and the mounting bracket, which has a transparent opening and attaches accessories, has vertical slits on both ends of the leg and is attached to the inside of the lighting fixture body. The mounting spring attached to the mounting bracket is inserted between both locking pieces protruding from the slit, and is inserted into and locked into the slit. It is easy to install, has a simple structure, and has the advantage of being inexpensive and improving the workability of installation, lamp replacement, etc.
