Description

The present invention improves the sense of brightness by applying light to an irradiation surface such as a ceiling.

In order to irradiate an irradiation surface such as a ceiling with light, there is a technique in which a light-emitting portion protrudes from the irradiation surface, and side light distribution from the light-emitting portion is used to brighten the irradiation surface. (For example, see Patent Document 1 and Patent Document 2.)

Japanese Patent Application Laid-Open No. 2018-6320 JP 2014-72077 A

The decorative cover 500 is attached to the lamp main body 110 so that one side in the longitudinal direction is adjacent to the light source section 200 and the other side thereof forms an opening (space) with the inner wall of the lamp main body 110. be done. The opening (space) formed between the inner wall of the lamp main body 110 is a so-called air-conditioning return hole 101. If the specifications of the lighting fixture 1000 do not require the air-conditioning return hole 101, the decorative cover 500 and the fixture The other side of the decorative cover 500 may be adjacent to the inner wall of the lamp main body 110 so that no opening (space) is provided between it and the inner wall of the main body 110 .

The power supply unit 600 is attached to the top plate portion 111 of one of the two lamp main bodies 110, and includes a power terminal block 700, a dimming signal terminal block 800, and two light source units 200 (LED modules). 230) via electric wires.

The power terminal block 700 is attached to the connecting plate 320 of one of the two connecting tools 300, and is connected to a power supply line drawn from the outside.

The dimming signal terminal block 800 is attached to the connecting plate 320 of one of the two connecting tools 300, and is connected to an external device (such as a dimming controller) via a communication line. In the present embodiment, the terminal block 700 is attached adjacent to the power supply terminal block 700. However, the present invention is not limited to this. Therefore, if the dimming signal line is unnecessary, it may not be provided.

Next, the process of attaching lighting fixture 1000 according to the present embodiment to the system ceiling (T-bar 2000) will be described with reference to FIGS. 7 to 9. FIG.
FIG. 7 is a comparative example for comparison with the mounting process of the present embodiment, FIG. 8 is a diagram showing the mounting process of the present embodiment, and FIG. 9 is for explaining partial details of the mounting process of FIG. is a diagram.

First, the power line wired to the ceiling is attached to the power terminal block 700, and the lamp 100 is tilted from the lower side of the system ceiling where the T-bar 2000 is assembled in a grid pattern so that the lower surface side of the lamp 100 is the T-bar. 2000 is inserted so as to get over the upper end thereof (see the steps shown in FIGS. 7(a) to 7(b) and 8(a) to 8(b)). At this time, when the light source unit 200 is attached to the lamp 100, as shown in FIG. (dimension Ho shown in FIG. 7(b)) is required. Also, when the light source unit 200 is attached to the lamp 100, the translucent cover 240 (translucent portion 242), which is the light emitting portion of the light source unit 200, is positioned at the upper end of the T-bar 2000 (the arrow shown in FIG. 7B). There is a risk of contact with the sight A). In this case, when the lighting device 1000 is slid and attached, the light-transmitting cover 240 (light-transmitting portion 242) rubs against the upper end of the T-bar 2000, causing the light-transmitting cover 240 (light-transmitting portion 242) may be damaged.

However, in the lighting fixture 1000 of the present embodiment, the light source unit 200 can be removed from the lamp 100. Therefore, as shown in FIG. 2000 (perspective view B shown in FIG. 8(b)), the inclination of the lamp 100 can be made shallower, and the depth of the ceiling of the system ceiling (the dimension H1 shown in FIG. 8(b)). The lamp 100 can be easily attached even when the amount of light is small, and the installation work for attaching the lamp 100 to the system ceiling can be improved. It is possible to prevent the translucent cover 240 (translucent portion 242) from being damaged.

After inserting the lighting fixture 100 into the ceiling back side of the system ceiling (upper end side of the T-bar), tilting the lighting fixture 100 so that it is almost parallel to the T-bar 2000, the frame surrounded by the four T-bars 2000 After that, the lamp 100 is fitted into the frame (see the mounting process shown in FIGS. 7B to 7C and 8B to 8C). At this time, by engaging the T-bar mounting portion 410 with the upper end portion of the T-bar 2000, the lamp 100 is attached to the system ceiling.

Next, with the lamp 100 attached to the system ceiling, the mounting pins 530 of the decorative cover 500 are slid to insert the decorative cover 500 into the inner wall side of the lamp main body 110 and attach it to the lamp main body 110 . At this time, openings are formed between the lamp main body 110 and the inner wall on both sides of the decorative cover 500 in the longitudinal direction. One side of this opening (peripheral side of the fixture body) is for attaching the light source section 200, and the other side (inner side of the fixture body) is an air conditioning return hole 101 for air conditioning.

Next, the light source unit 200 is attached to the lamp 100 (lamp main body 110) attached to the system ceiling. At this time, first, a wire (connector) drawn out from the power source section 600 attached to the lamp main body 110 is connected, and the mounting spring 140 is inserted into the opening of the engaged section 220 (mounting spring engaging section 222). Then, the light source unit 200 is pushed up toward the lamp main body 110, so that the light source unit 200 can be attached to the lamp main body 110 (see the mounting process in FIG. 8D).

Therefore, since the light source section 200 is attached to the lighting fixture 100 after the lighting fixture 100 is attached to the system ceiling, there is no fear that the translucent cover 240 of the light source section 200 will be damaged.

In addition, if the frame engaging portion 241 of the light source portion 200 (the portion indicated by the arrow C in FIG. 9A) is a translucent member, the light from the LED 232 is guided (for example, the light entering the translucent portion is reflected inside the translucent part 242 and guided to the frame engaging part 241), it may appear as if it is shining. It is dark and glowing. Alternatively, the frame engaging portion 241 is not illuminated at all (for example, when the light is not guided as described above, or when the frame engaging portion 241 is made of an opaque material).

In such a case, when the light source unit 200 is attached to the lamp 100, at least the frame engaging portion 241 of the translucent cover 240 enters the inside of the lamp main body 110 (see the arrow in FIG. 9B). Part C) makes it possible to cover the edges of the lamp body 110 and the decorative cover 500, that is, to cover up the portion of the light source unit 200 that emits little light or does not emit light. It is possible to improve the designability in

Further, by arranging the light source unit 200 so as to be adjacent to one side of the lamp body 110, one side of both sides in the short direction of the light source unit 200 can be covered with the lamp body 110, thereby reducing the number of parts. By (providing a decorative cover on the other side), the frame engaging portions 241 on both sides of the light source portion 200 can be covered, and the design can be improved while suppressing part costs and work man-hours.

In addition, by attaching two light source units 200 to both end sides of the lamp 100 so that they are separated from each other, the light emitted from the light source units 200 in the side direction can be applied to the ceiling material. The sense of brightness can be improved, and glare can be reduced by brightening the surroundings of the light source unit 200 .
