Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTIVES OF THE INVENTION (INDUSTRIAL APPLICATION FIELD) The present invention relates to a lighting fixture with a reflective mirror, such as a recessed downlight fixture or a floodlight.

(Prior art) Conventionally, in lighting equipment, for example,
As shown in Publication No. 3082, a plurality of mirror supports are attached to the lower part of the main body, the edge of the reflecting mirror is locked to the locking part formed at the lower end of each mirror support, and the upper part of the reflecting mirror is It is known that a coil spring is stretched between the reflector and the main body, and the reflecting mirror is held by the coil spring.

(Problem to be solved by the invention) The above-mentioned lighting equipment can be easily attached and detached by inserting and removing the reflecting mirror from below, but on the other hand, the reflecting mirror is fixed by the elasticity of the coil spring. Therefore, if the reflecting mirror is carelessly pushed up in an oblique direction, such as when attaching or removing the lamp, the reflecting mirror will come off and fall together with the coil spring. To prevent this,
If the force of the spring is increased to strengthen the fixing force of the reflecting mirror, excessive force will be required when attaching and detaching the reflecting mirror, which is undesirable.

The present invention is intended to solve the above-mentioned problems, and aims to securely fix the reflecting mirror.

[Structure of the idea]

(Means for Solving the Problems) In the lighting device of the present invention, a socket mounting frame is attached to the upper side of the main body which is open at the bottom, a lamp socket is attached to the lower part of this socket mounting frame, and the socket mounting frame is attached to the socket mounting frame. Attach the upper parts of the mirror supports on both sides that have spring properties and have mirror support pieces at the lower ends, and install a presser plate between the upper parts of the mirror supports on both sides. The engaging part in the flange part is engaged, the fixing plate is fitted into the fitting part on the upper part of the reflecting mirror, and a coil spring is interposed between the holding plate and the fixing plate, and both sides of the fixing plate are fitted. are fixed to the mirror supports on both sides.

(Function) This invention fits a fixing plate and a coil spring into the upper fitting part of the reflecting mirror, inserts them from below between the mirror supports on both sides, and then attaches the reflecting mirror to the mirror support pieces of the mirror supports on both sides. The reflecting mirror is temporarily fixed by this, and then the fixing plate is fixed to the mirror supports on both sides with screws or the like.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The figure shows a recessed downlight fixture.

Attachment holes 7, 8, and 9 are bored on both sides of the hole 6, on both sides, and in the attachment pieces 5 on both sides, respectively. The socket mounting frame 4 is mounted to the lower surface of the upper side of the main body 1 through mounting holes 3 and 9 with screws 10.

Reference numeral 11 denotes a lamp socket, and a mounting hole 12 is bored in the upper surface of the lamp socket. The lamp socket 11 is attached to the lower surface of the socket attachment frame 4 through the attachment holes 7 and 12 with screws 13, and a lamp 14 is attached to the lower part of the lamp socket 11.

Reference numeral 15 denotes a pair of mirror supports on both sides made of a metal plate material having spring properties, and a vertical mounting side 17 is formed on the upper part through a shoulder 16 and a mirror support piece 18 is formed on the inside of the lower end. Attachment holes 19, 20, and 21 are formed in the portion 17 and the intermediate portion, respectively. The upper mounting side portions 17 of the mirror supports 15 on both sides are connected to the screws 2 through the mounting holes 8 and 20 on both sides of the socket mounting frame 4.
It is installed with 2.

Reference numeral 23 denotes a disc-shaped holding plate, which has a lamp hole 24 in the center and mounting holes 25 on both sides.
The holding plate 23 is disposed between the mirror supports 15 on both sides, and the mounting hole 1 is located at the shoulder portion 16.
It is attached with screws 26 via 9 and 25.

Reference numeral 27 denotes a reflective mirror made of glass, which has a lamp hole 28 at its upper part and a cylindrical fitting part 29 formed around it, and a flange part 30 around its lower end and which engages on both sides of this flange part 30. A portion 31 is cut out. The reflecting mirror 27 is supported by engaging the engaging portions 31 on both sides with the mirror support pieces 18 of the mirror supports 15 on both sides.

Reference numeral 32 denotes a disk-shaped fixing plate, which has a mirror fitting hole 33 in the center and L-shaped attachment parts 34 on both sides, and an attachment hole 35 is bored in the attachment part 34 . The fixing plate 32 has its mirror fitting hole 33
The lower part of the coil spring 36, which is fitted into the fitting part 29 of the reflecting mirror 27 and which is interposed between the presser plate 23 and the fixing plate 32, is connected to the fitting part 2.
9 , and the attachment portions 34 on both sides are attached to the mirror supports 15 on both sides with screws 37 through the attachment holes 21 and 35 .

Reference numeral 38 denotes a power cord connected to the lamp socket 11 and led out from the power cord holes 2 and 6 of the main body 1 and the socket mounting frame 4. 39 is the ceiling, and 40 is a decorative frame.

Next, the operation of attaching and detaching the reflecting mirror 27 will be explained.

When attaching the reflecting mirror 27, attach the fixing plate 32 and coil spring 36 to the fitting part 29 of the reflecting mirror 27 with the socket mounting frame 4, lamp socket 11, mirror support 15, and presser plate 23 attached to the main body 1. The coil springs 36 are fitted in sequence, and the upper ends of the coil springs 36 are pressed against the holding plate 23 from below, and the mirror supports 15 on both sides are attached to each engaging portion 31 on the flange portion 30 of the reflecting mirror 27.
The reflecting mirror 27 is temporarily fixed by the elasticity of the coil spring 36.

Next, the mounting portion 34 of the fixed plate 32 and the mirror support 15 are aligned with each other, and the mounting holes 21, 3 are aligned.
Fix the fixing plate 32 with screws 37 through 5,
The reflecting mirror 27 is fixed. And lamp 14
Attach it to the lamp socket 11.

When the reflecting mirror 27 is to be removed, the fixing plate 32 is released from the mirror support 15 by removing the screw 37, and the reflecting mirror 27 is pulled out together with the fixing plate 32 and the coil spring 36 downward.

Note that the mirror supports 15 on both sides may be integrally formed by connecting their upper parts, and this may be attached to the socket mounting frame 4, and the mounting hole 21 for mounting the fixing plate 32 of the mirror support 15 is a long hole in the vertical direction. However, if it is a long hole, it can be temporarily attached using the mounting screw 37 and moved together with the coil spring 36, and the coil spring 36 can be attached to the fixed plate 32 in advance.

In addition, each mounting screw 10, 13, 22, 37
may be by other fasteners.

[Effects of the invention] According to the invention, the fixing plate fitted into the fitting portion of the reflecting mirror is temporarily fixed by being pressed against the reflecting mirror by a coil spring, and then the fixing plate is fixed to the mirror support from both sides with screws, etc. As a result, the reflecting mirror is fixed without moving and will not come off even if force is applied from the outside, allowing safe use. Further, since the coil spring is only used for temporary fixing, even one with weak elastic force can be used.
