Description

[Detailed Description of the Invention] This invention relates to lighting equipment such as downlights, and aims to facilitate the replacement of lamps and the transportation of ballast boxes and equipment.

An embodiment of this invention is shown in FIGS. 1 and 2.

That is, this downlight is composed of a fixture body 1, a ballast box 2, and a socket stand 3.

The appliance body 1 is made up of an upper hanging plate 4 with a hole 4a and a lower mounting frame 5 connected by a plurality of vertical arms 6, and is attached to an opening 8 in a ceiling 7 by normal means.

A reflector plate 9 having a hole 9a in the top is arranged inside the instrument main body 1.

The ballast box 2 has an upper cover 11 and a lower cover 12 above and below the support fitting 10.
and the outer periphery is covered with a cover 13, and the upper lid 1
1 and a lamp through hole 14.15 is formed in the center of the lower lid 12, and a ballast 16.15 is divided into a plurality of parts between the support fitting 10 and the cover 13. Power factor improvement capacitor 1
7 and an optical compensation device 18, and further includes a through hole 14.
An incandescent lamp socket 19 is provided at the corner of 15, and an incandescent lamp 20 for light compensation is mounted.

21 is a power cord. This ballast box 2 is the device main body 1
It is detachably attached to the upper surface with screws or the like (not shown), and the reflecting plate 9 is attached to the lower end of the support fitting 10 with thumbscrews 22.

Furthermore, a pair of mounting screws 23 are temporarily tightened on the top surface of the ballast box 2.

The socket stand 3 has a socket 2 in the center of the strip plate 24 which has a U-shaped cross section.
5 is attached, pothole holes 26 are formed at both ends of the band plate 24 in different directions, and handles 27 are provided on both sides of the plate so as to be rotatable in the direction of the arrow.

Attach the HID lamp 28 or mini halogen lamp to the socket 25, insert the lamp 28 into the through hole 14.15, pass the large diameter side of the potbellied hole 26 through the pair of mounting screws 23, and rotate the socket base 3 laterally. When the socket base 3 is moved and the mounting screw 23 is tightened on the small diameter side of the pothole 26, the socket base 3 is fixed to the ballast box 2.

At this time, the lamp 28 is located at a predetermined position on the reflector plate 90 due to the dimensional relationship.

With this structure, when replacing the lamp from the ceiling, you can shake the mounting screw 23, rotate the socket base 3 in the opposite direction to the above, raise the handle 27, and pull out the lamp by hand. , lamp replacement becomes easier.

Also, when transporting equipment, use the socket stand 3. Stabilizer box 29 main body 1
When both are integrated, the handle 27 can be held in the hand for transportation, and since the instrument is heavy and has a handle for transportation, the transportation work can be reduced.

Furthermore, when installing the equipment, first install the main body 1 on the ceiling surface,
The ballast box 2 can be carried by holding the handle 27 of the ballast box 2 in your hand, and the ballast box 2 can be attached to the main body 1.
Because it is a particularly heavy item, it is easy to transport.

As described above, in the lighting fixture of this invention, the socket base, ballast box, and fixture body are separated and detachable from each other, and the socket base is provided with a handle, making it easy to replace the lamp and the ballast box and fixture body. This has the effect of making transportation easier.
