DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this embedded type lighting fixture has a fixture main body 1, a first reflector 2 and a second reflector 3, a plurality of lamp sockets 4, a terminal block 5, a first lighting device 6, And a second lighting device 7.

The instrument body 1 is box-shaped having an opening 8.
In the embodiment, the opening 8 has a rectangular shape, one opposing side wall 9 facing the longitudinal direction is formed vertically, and the other opposing side wall 10 is formed.
Is inclined symmetrically so that the cross section including the back wall forms a trapezoid. An outer collar 11 is formed at the edge of the opening 8, and when embedded in an embedded hole (not shown) in the ceiling, the outer collar 11 is locked to the edge of the embedded hole. 12 is a main body mounting portion provided at four places, and 13 is a feeder line introduction hole.

The first reflector 2 and the second reflector 3 are each chevron-shaped, and are mounted inside the instrument body 1 with the longitudinal direction facing the opposite side wall 9 of the instrument body 1. In the embodiment, the first reflector 2 has a substantially V-shape, and the first reflector 2 is provided at a position covering the pair of main body mounting portions 12 and the feeder line introduction holes 13, and the second reflector 3 is provided with the other pair of main body mounting portions 12. Each end is in contact with one opposing side wall 9.

The plurality of lamp sockets 4 are provided on one side wall 9.
The lamp 14 is attached to the side of the first reflector 2 and the second reflector 3 and arranged in parallel to the sides of the first reflector 2 and the second reflector 3. I have. The lamp of the embodiment is three straight tube fluorescent lamps, and the lamp sockets 4 are provided on both sides of the first reflection plate 2 and the second reflection plate 3 on the one side wall 9.

The terminal block 5 and the first lighting device 6 are
Are arranged inside the reflection plate 2. The terminal block 5 according to the embodiment is arranged near the feed line introduction hole 13. First
The lighting device 6 includes a two-light ballast, and supplies power to the lamp sockets 4 of the pair of lamps 14 adjacent to the first reflector 2 by the lamp wires 23. The second lighting device 7 is disposed inside the second reflector 3, is constituted by a ballast and the like, and is supplied with power to the remaining lamp sockets 4 by the lamp wires 23.

In this lighting apparatus, a line insertion hole 15 is formed inside one of the first reflection plate 2 and the second reflection plate 3 of the one opposing side wall 9 so that the terminal block 5 and the first lighting device are formed. 6 is connected by a first power supply line 16, and the terminal block 5 and the second lighting device 7 are connected by a second power supply line 17 through a wire insertion hole 15. That is, the terminal block 5
, A second power supply line 17 is drawn along the inside of the first reflection plate 2 to the end, drawn out of the device main body 1 through the wire insertion hole 15, and again returned to the second reflection plate from another wire insertion hole 15. 3 and is connected to the second lighting device 7 through the second reflection plate 3. The wire insertion hole 15 of the embodiment is disposed close to the outer collar 11.

Reference numeral 18 denotes a metal wire hiding tool, which is formed in a substantially L-shape. The upper piece 19 is overlapped with the instrument body 1 and the tip of the lower piece 20 is bent outward to form a bent piece 21. The second power line 1 is located inside the rising piece 22 at the tip of the outer collar 11.
7 is hidden. According to this embodiment, the second power supply line 17 is connected to the first reflection plate 2 and the wire insertion hole 15 of the instrument body 1.
And the second power supply line 17 in the opening 8 can be prevented from being exposed.
Since the power supply line 17 and the lamp line 23 can be isolated by the apparatus main body 1 and the reflection plates 2 and 3, noise can be reduced.

The wire hiding device 18 covers and protects the second power supply line 17 protruding from the outer surface of the device main body 1. Legal regulations are cleared so that exposure to the outside does not exceed 80 mm. In addition, the effect of regulating the clearance between the instrument body 1 and the embedding hole can be obtained, and the appearance of the instrument can be improved.

The present invention can be applied to an apparatus having at least two lighting devices and lamps.

[0017]

According to the lighting apparatus of the first aspect, since the second power supply line is wired through the first reflector, the wire insertion hole of the apparatus main body, and the second reflector, the power supply in the opening is provided. The exposure of the wire can be prevented, and the second power supply wire and the lamp wire can be isolated from each other by the instrument body and the reflector, so that noise can be reduced.
