Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a lighting fixture such as a ceiling light.

[0002]

[Prior art]

 Conventional lighting fixtures are shown in FIGS. FIG. 5 is a plan view of the luminaire, and 30 is a box-shaped luminaire main body having an opened lower surface, and a power line insertion hole 31 and an attachment hole 32 are formed on the upper surface. FIG. 6 is a sectional view of the luminaire, and a reflector 33 and a lamp 34 are provided in the luminaire body 30. Further, on the back surface of the reflection plate 33, electric components such as a ballast 35 and a terminal block 36 (FIG. 5) are built in.

[0003]

[Problems to be solved by the device]

 According to the conventional lighting fixture, the depth h'of the rear surface space of the reflection plate 33 can accommodate the ballast 35 as shown in FIG. 6 and can be inserted into the power line insertion hole 31 as shown in FIG. The power supply line 37 needs to be large enough so that it can be connected to the terminal block 36. Therefore, there is a problem that the height H ′ of the fixture main body 30 becomes large and the depth of the lighting fixture embedded in the ceiling and the like also becomes large, and the influence of the interaction with the structural material of the ceiling becomes large. There was a problem that the appearance would be poor if it was installed directly on the ceiling. This also applies to lighting fixtures for two or more lights, and the height of the fixture was uniformly determined by the size of the electrical components housed in the space behind the reflector.

An object of the present invention is to provide a lighting fixture that can be made thinner.

[0005]

[Means for Solving the Problems]

 The lighting device according to claim 1 has a box-shaped device body having an open front surface, a reflection plate provided in the device body and having a substantially chevron cross-section, and between a corner of the device body and an inclined surface of the reflection plate. It is equipped with electrical parts installed in space. The lighting fixture according to claim 2 is a box-shaped fixture main body having a front surface opening and a power supply wire insertion hole on the back surface, a reflector having a substantially chevron cross section provided in the fixture main body, and a power supply wire insertion hole near the box. And a terminal block for connecting the power supply line installed in the space between the corner of the instrument body and the inclined surface of the reflector.

According to a third aspect of the present invention, there is provided a luminaire having a box-shaped main body having an open front surface, a reflector having a substantially chevron cross section provided in the main body of the luminaire, and a back surface space of the reflector in a longitudinal direction of the main body of the luminaire. It is provided with a pair of reinforcing plates arranged side by side, and an electrical component installed between the pair of reinforcing plates in a space between the entry corner of the instrument body and the inclined surface of the reflector.

[0007]

[Action]

 According to the configuration of this invention, since the electric component is installed in the space between the corner of the instrument body and the inclined surface of the reflector having a substantially chevron cross section, the depth of the back space of the reflector is accommodated. It is no longer determined by the size of the electrical components.

【Example】

 One embodiment of this invention is shown in FIGS. FIG. 1 is a plan view of the luminaire, and 10 is a box-shaped luminaire main body having an opened lower surface, and power line insertion holes 11 and 12 and a mounting hole 13 are formed on the upper surface. FIG. 2 is a sectional view of the luminaire, and a reflector 14 having a substantially chevron cross section, a socket (not shown) and a lamp 15 are provided in the luminaire body 10.

Then, the ballast 16 and the power line connecting terminal block 17 are installed in the space 20 between the entry corner 18 of the instrument body 10 and the inclined surface 19 of the reflector 14. The terminal block 17 is installed in the vicinity of the power wire insertion hole 12, and the distance X is preferably about 50 to 60 m / m (FIG. 1). The terminal block 17 may be provided near the power supply line insertion hole 11. Further, a distance Y = 0 to 10 m / m (FIG. 2) between the ballast 16 and the inner surface of the side wall of the instrument body 10 is desirable.

According to the luminaire thus configured, the ballast 16 and the terminal block 17 are installed in the space 20 between the entry corner 18 of the luminaire body 10 and the inclined surface 19 of the reflector plate 14. The depth h (FIG. 2) of the rear surface space of the reflector 14 is not determined by the size of the electric components such as the ballast 16 and the terminal block 17 to be housed. Therefore, the height H of the device can be reduced, and in the case of the embedded device, the influence of the interaction with the structural material behind the ceiling is small, and in the case of the directly attached device, the device can be made thin, which is good-looking.

Further, since the device can be made thinner, the number of packing people can be reduced and the cost can be reduced. Further, since the terminal block 17 is provided in the vicinity of the power line insertion hole 12, the length of the power line connected to the terminal block 17 may be the same as the conventional one. Although the ballast 16 and the terminal block 17 are installed in the space 20 in the above-mentioned embodiment, only one of the ballast 16 and the terminal block 17 may be installed in the space 20. Further, electric parts may be installed in spaces on both sides between the corners 18 on both sides of the instrument body 10 and the inclined surfaces 19 of the reflector 14.

Another embodiment of the present invention is shown in FIGS. 3 and 4. The same parts as those in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, a pair of reinforcing plates 25 and 26 are arranged in the space on the back surface of the reflecting plate 14 in the longitudinal direction of the instrument body 10 in the vicinity of the mounting holes 13, respectively. The ballast 16 and the terminal block 17 are installed in the space 20 between the pair of reinforcing plates 25 and 26.

Also in the luminaire thus configured, the same effect as that of the first embodiment can be obtained. Further, since the ballast 16 and the terminal block 17 are arranged between the pair of reinforcing plates 25 and 26, the ballast 16 and the terminal block 17 can be easily connected.

[0014]

EFFECTS OF THE INVENTION According to the luminaire of the present invention, since the electric parts are installed in the space between the corner of the main body of the luminaire and the inclined surface of the reflection plate having a substantially chevron cross section, the rear space of the reflection plate The depth is not determined by the size of the electrical components to be stored, and the effect is that the equipment can be made thinner.
