Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to lighting equipment.

(Prior Art) In a lighting fixture for a system supported by a T-bar, a louver is sometimes installed inside a reflector plate attached to the lower surface of the fixture body. In this case, there is no particular problem when the louver is installed on the fixture body from the beginning, but there is a problem when the louver is installed later on an existing lighting fixture.

In this case, in the past, a mounting bracket was fixed to the reflector using screws or the like, and the louver was attached to the reflector using the mounting bracket.

(Problem to be solved by the invention) According to the conventional configuration described above, inside the reflector,
The disadvantage is that the screws, mounting hardware, etc. become exposed and visible, which seriously spoils the appearance.

The purpose of this invention is to make it possible to attach the louver to the appliance body without exposing its mounting hardware.

(Means for Solving the Problem) This invention uses a receiving bracket supported across a pair of T-bars that hold the fixture body, and a louver inserted into the end plate of the fixture body into the interior of the reflector of the lighting fixture. The louver is supported by inserting the louver between the louver and the end of the louver, and engaging the downwardly bent bent edge installed on the louver with the upper end of the upstanding wall provided on the receiving metal fitting. .

(Function) The receiving fitting is supported by being inserted across the T-bar. The louver is installed so that the end portion of the louver rests on the receiving metal fitting supported in this manner. This allows the louver to be installed inside the reflector.

(Example) This invention will be explained using figures. 1 is the main body of the instrument, in this example, a pair of side channels 2;
A socket base 3 installed across both ends of both side channels 2, and this socket base 3.
It mainly consists of a socket 4 supported by a socket 4, and an end plate 5 which is approximately L-shaped. Reference numeral 6 indicates a fluorescent lamp, and reference numeral 7 indicates a reflector plate, which can be attached to, for example, the socket base 3 with screws.

Reference numeral 8 denotes a pair of T-bars that are hung from the ceiling, etc., and the lower end of the mounting bracket 9 attached to the side channel 2 rests on the head 10 of the T-bar 8. This allows the instrument body 1 to be supported by the T-bar 8.

Reference numeral 11 denotes a louver that will be placed inside the reflecting plate 7 later. Louver 11 is louver frame 12
and a plurality of wings 13 provided on the louver frame 12. The above configuration is not particularly different from ordinary lighting equipment of this type.

According to this idea, a receiving fitting 14 for receiving the louver 11 is provided. The receiving metal fitting 11 is
It is formed by a metal fitting main body 15 having a length sufficient to span between both T-bars 8, and standing walls 16 and 17 erected from both side edges of the metal fitting main body 15. Further, a bent edge 18 is provided that bends downward from the louver 11, specifically, from the louver frame 12.

Next, the installation work of the louver 11 will be explained. The receiving fitting 14 is used at the end of this installation work. First, the louver 11 is inserted into the reflection plate 7 from its bottom surface. Since the width and length of the louver 11 are approximately equal to the width and length of the lower surface of the reflecting plate 7, it is possible to pass through the lower surface of the reflecting plate 7 and insert it inside.

Next, the receiving metal fitting 14 is installed inside the reflecting plate 7 so as to span between both T-bars 8. Since the receiving fitting 14 is formed to be slightly longer than the width of the reflecting plate 7, the receiving fitting 14 is first tilted as shown by the dotted line in FIG. 7, and then inserted into the reflecting plate 7.

Next, the receiving metal fitting 14 is rotated so as to be perpendicular to the longitudinal direction of the reflecting plate 7. Due to this rotation, both ends of the receiving metal fitting 14 rest on the T-bar 8. As a result, the receiving fitting 14 is supported by the T-bar 8.

After that, the louver 11 that had been pushed upward until then is lowered, and the bent edge 18 is moved to the receiving metal fitting 14.
The upper end of the upright wall 17 is engaged with the upper end of the upright wall 17. As a result, the louver 11 is installed inside the reflecting plate 7 and is supported by the receiving fitting 14.

Further, the receiving metal fitting 14 is sandwiched between the end of the louver 11 and the end plate 5, and thereby the receiving metal fitting 14 is fixed.

In this supported state, the gap between the upright wall 17 and the louver frame 12 is covered from above by the bent edge 18. Therefore, the light from the fluorescent lamp 6 will not leak downward through this gap.

Further, due to the engagement between the bent edge 18 and the upright wall 17, the movement of the louver 11 in its longitudinal direction is restricted.

Note that by adjusting the height of the upright wall 17 of the receiving fitting 14 by setting it to the same height as the louver frame 12, the lower surface of the louver frame 12 and the lower surface of the receiving fitting 14 can be made to match. . Therefore, it is possible to avoid problems such as creating a step here that spoils the appearance.

Further, in this invention, both ends of the upright wall 17 are bent inward to form a bent edge 19, which faces the side surface of the louver frame 12, thereby restraining movement of the louver frame 12 in the width direction. ing.

(Effects of the invention) As described in detail above, according to this invention, in a lighting fixture that is attached to a T-bar, a downwardly bent portion installed in a louver frame is attached to the upper end of an upright wall of a receiving bracket whose both ends rest on the T-bar. Because all you have to do is engage the bent edges of the louver, when installing the louver in a lighting fixture that does not have a configuration for installing a louver, there is no need for conventional mounting hardware, screws, etc. The bracket supporting the louver is simply installed at the end of the reflector so that it straddles the T-bar, so it does not detract from the appearance of the lighting fixture, and furthermore, light can be filtered through the gap between the bracket and the louver frame. In addition, since the bent edge of the receiving metal fitting faces the side surface of the louver frame, the movement of the louver frame in the width direction can be easily restrained.
