Description

[Detailed description of the invention] Industrial field of application This invention relates to a lighting device installed on a study desk, etc. Specifically, the invention relates to a lighting device installed on a study desk, etc. , relates to a mounting structure for a sliding type lighting fixture in a lighting device equipped with a sliding type lighting fixture for the purpose of auxiliary lighting.

Conventional technology A study desk with a shelf has a straight tube fluorescent lamp lighting fixture located under the desk shelf that illuminates almost the entire desk surface, and an incandescent lamp lighting fixture that serves a supplementary role to selectively illuminate the desk top. It is common to have two of these installed.
The latter type of incandescent lamp lighting equipment is commonly known as a spot light, and this spot light is installed so that it can be slid left and right under a shelf, or it can be installed in a fixed position under a shelf to the left and right so that it can selectively illuminate a wide area of the desk. Those mounted so that they can swing are prized.

The sliding spotlights mentioned above are generally supported by rails fixedly placed under the shelf.
A conventional example of a lighting device for a study desk in which a sliding type spotlight and a lighting fixture for a straight tube fluorescent lamp are attached under a shelf board will be described below with reference to FIGS. 9 to 12.

In the figure, 1 is a desk, 2 is a shelf fixed on the desk, 3 is a shelf board of shelf 2, and 4 is a lighting device attached to the lower front part of the shelf board 3, and is directly attached to the lower surface of the shelf board 3. It has a first lighting fixture 5 for a straight tube fluorescent lamp, and a spotlight 6 which is a sliding second lighting fixture for an incandescent lamp. 7 in the first lighting fixture 5
is a reverse gutter-shaped appliance body fixed under the shelf board 3 with a plurality of wood screws 8, 8, 9, 9 is a pair of sockets fixed to both ends of the lower surface of the appliance body 7, 10 is the appliance body A resin outlet box screwed to the bottom of one end of 7, in which a blinking switch 11 for straight tube fluorescent lamps and a blinking switch 1 for incandescent lamps are installed.
2, service outlets 13, 13, and fluorescent lamp lighting means such as a ballast (not shown) are housed. Reference numeral 14 denotes a straight tube fluorescent lamp attached to a pair of sockets 9,9. The top plate part 7a of the appliance main body 7 is fixed along the lower front part of the shelf board 3,
A plurality of reinforcing metal fittings 15, 15, . . . are attached to screws 16, 15, .
16..., and a rail 17 having a substantially C-shaped cross section for supporting a spotlight is fixed to reinforcing metal fittings 15, 15...
is fixed with screws 18, 18... Reference numeral 19 denotes a long cover having a substantially C-shaped cross section that covers the front wall 7b of the instrument main body 7 and the front surface of the rail 17, and is an extrusion molded product of resin.
The first lighting device 4 is attached in an inserting manner from one end of the rail 17 to improve the appearance of the first lighting device 4 from the front.

The spot light 6 includes an inverted dish-shaped shade 20, an incandescent lamp 21 housed in the shade 20, a first support fitting 22 extending from the rear of the shade 20, and a first support metal fitting 22 extending from the rear of the shade 20.
A decorative bolt 23 and a decorative nut 24 are attached to the support fitting 22.
The slider 27 has a resin slider 27 fixed to the second support metal fitting 25 with a screw 26, and the slider 27 is slidably inserted into the rail 17. The spot light 6 is installed by inserting the slider 27 to which the second support metal fitting 25 is screwed into the rail 17 fixed to the instrument body 7, and then attaching the first support metal fitting 22 extending from the shade 20 at an appropriate time. This is done by tightening the second support fitting 25 with a decorative bolt 23 and a decorative nut 24. The spotlight 6 is supported by the rail 17 via a slider 27 and reciprocated in the longitudinal direction of the rail 17 to selectively illuminate the desk.

Problems to be Solved by the Invention Since the spotlight 6 of the lighting device 4 is a sliding type, it selectively illuminates a wide area on the desk, making the use of the study desk convenient. However, the rail 17 that supports the spot light 6 so as to be movable from side to side is a long metal product made of aluminum or the like and is expensive. This made it difficult to

Therefore, an object of the present invention is to realize a cost reduction of a lighting device having a first lighting fixture for a straight tube fluorescent lamp and a sliding second lighting fixture.

Means for Solving the Problems The present invention provides a first lighting fixture for a straight tube fluorescent lamp, which has an inverted gutter-shaped fixture body directly attached to the front lower surface of a top plate for mounting the lighting fixture; A downward metal rail is attached to the front wall through reinforcing metal fittings each having a substantially C-shaped cross section and spaced apart from each other; a resin cover having a substantially C-shaped cross section, integrally having upward rail portions facing parallel to each other below the rail, and having the reinforcing metal fittings superimposed on the inner side; having a slider slidably supported therebetween at one end;
The above object is achieved with a lighting device characterized by comprising a second lighting fixture supported so as to be movable in the longitudinal direction of the fixture body via this slider.

Function: By supporting the slider of the second sliding lighting fixture from above and below by the rail and the rail part of the cover, it is possible to create a special rail that supports the second sliding lighting fixture with a simple and inexpensive structure such as an L-shaped cross section. can be used. In this case, the inner surface of the resin cover that has an integral upward rail is reinforced by overlapping the reinforcing metal fittings that also serve as the mounting metal fittings for the downward rail, which allows the resin cover to be made thinner and manufactured at low cost, and provides mechanical strength. It will be done.
