Description

[Detailed Description of the Invention] This invention relates to a direct-tube fluorescent lamp fixture with an exposed direct-mounted lamp, which is mainly used in stores and the like.

In general, it is desired that fluorescent lamps of this type be able to be selected in various colors, shapes, arrangements, etc., and combined to give them ornamental functions, but conventional straight pipes In fluorescent lamp fixtures, the lamps are large and rod-shaped, so a large space is required to arrange them in a desired design, which is not suitable for general stores.

In addition, there are a variety of appliances that use incandescent lamps, such as those that have regular polygonal shapes, and by combining and arranging these, you can create unique designs.
Although the above-mentioned requirements could be met, on the other hand, the luminous efficiency was low, so it was not preferable in view of the current situation in Japan, where energy conservation is a priority.

In view of these circumstances, the inventor of the present invention was able to configure and select various unique designs for the fixture itself while using straight tube fluorescent lamps, and also to create unique layout designs by combining these in various ways. Although we have proposed a straight tube fluorescent lamp fixture that can create the following, the purpose of this invention is to provide this as a more practical structure.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

In the figure, 1 is a ceiling, and 2 is a case 7.7' that is attached to the ceiling 1 and has a lighting device 21, a lamp socket 22, etc. attached therein.

8.8' are two sets of reflective cover mounting brackets that are fixed to the center and end portions of this case 2 and have L-shaped tips. 71 and 81 are formed to face each other.

Reference numerals 3 and 4 are two independent reflecting covers each having a triangular bottom and a shallow picture-like shape with an open upper part.Only the lamp socket 22 penetrates and protrudes to the outside, and the tops 3' and 4' of each are connected to the case 2. It covers the case 2 attached to the reflective cover mounting brackets 7, 7', 8, 8' so as to closely face each other in the center.

6 is a joint 5 formed between the tops 3' and 4' of the reflective covers 3 and 4, and between the case 2 and the tops 3' and 4' of the reflective cover 3J'4 so as to prevent the case 2 from being exposed. with the case cover provided on the reflective cover mounting bracket 7.
.

As shown in FIG. 4, this case cover 6 is assembled by fitting one of the insertion holes 61 into one of the reflective cover mounting brackets 7 at the center of the cheese 2, and then shifting it to the other reflective cover mounting bracket 8 side. Connect the reflective cover mounting bracket 8 to the remaining insertion hole 6.
2 and is installed in a so-called drop-in type.

Note that 9 is a thumbscrew for attaching the reflective cover, and 10 is a fluorescent lamp.

In the straight tube fluorescent lamp apparatus constructed in this way, the reflective covers 3 and 4 are attached to the case 2 closely facing each other due to decorative requirements, and the joint between the reflective covers 3 and 4 is formed on the surface of the case 2. 5 is formed, the case cover 6 hides the part corresponding to the seam 5, so that unsightly things such as the lighting device 21 installed inside the case 2 and internal wiring (not shown) are not exposed. Therefore, a wider range of combinations of the reflective covers 3 and 4 as shown in FIG. 5, for example, is possible without compromising the appearance of the lighting fixture.

In addition, in the above embodiment, the reflective cover mounting bracket 7,
Although the tips of the horizontal portions 71.81 of No. 8 are made to face each other, the same effect as in the above embodiment can be obtained even when the tips of the horizontal portions 71.81 are made to face each other as shown in FIG. One thing is obvious.

FIG. 7 shows one reflective cover mounting bracket 7 made of an elastic metal material, and an insertion hole 61 of the case cover 6.
, 62 The center side edge spacing of the case is set to be slightly larger than the mounting spacing between the reflective cover mounting brackets 7 and 8, and the insertion hole 61 on one side of the case cover 6 is fitted into the reflective cover mounting bracket 7 made of elastic metal. Then, tilt the reflective cover mounting bracket 7 in the longitudinal direction of the case (indicated by the chain line in the figure), fit the other case cover insertion hole 62 into the other reflective cover mounting bracket 8, and then insert the reflective cover mounting bracket 7. This shows another example in which the case cover 6 is held by this elastic force by returning to its original shape.

According to this, when the reflective cover 3.4 is removed from the case 2, the effect of preventing the case cover 6 from falling off accidentally can be expected.

In addition, while the horizontal parts 71 and 81 of the reflective cover mounting brackets 7 and 8 are turned away from each other as shown in FIG.
One side 7 of the reflective cover mounting bracket is made of an elastic metal material similar to the one shown in FIG. The mounting brackets 7 and 8 should be installed smaller than the spacing.
After fitting the reflective cover mounting bracket 7 made of elastic metal into the insertion hole 61 of one side of the case cover 6, tilt the reflective cover mounting bracket 7 toward the center of the case 2, and insert the reflective cover mounting bracket 7 into the other reflective cover mounting bracket 8. By fitting the case cover insertion hole 6 into the case cover insertion hole 6 and then returning the reflective cover fitting 7 to its original shape, it becomes possible to press and hold the case cover 6 with both the reflective cover fittings 7 and 8.

As explained above, this idea consists of a case that is covered by a series of independent reflective covers, and a case cover that hides the case is attached to the joint on the case surface formed by the reflective covers. It is a simple structure that does not make the appearance of the lighting equipment bad.
It is possible to provide a practically useful straight tube fluorescent lamp fixture that enables a wide range of combinations of reflection powers.
