Description

[Detailed description of the invention] This invention relates to a lighting fixture with a built-in straight fluorescent tube.
In particular, multiple straight fluorescent tubes are housed with gaps,
If the front surface is covered with a transparent cover and a receiver is installed in the gap between the fluorescent tubes to receive signals from the transmitter of the remote control device for lighting equipment and control the lighting of the fluorescent tubes, this reception This invention relates to a device that prevents shadows from forming inside a lighting fixture when a fluorescent tube is turned on.

That is, when using a receiver having an elongated rectangular housing 9' as shown in FIG.
When a rectangular housing 9' is installed in the gap, part of the light from the fluorescent tubes 3, 3 is blocked by the sides of the housing 9', and as a result, the bottom surface 16 of the housing becomes dark and transparent. A shadow due to the dark bottom surface 16 is formed on the surface of the light cover 5, spoiling the aesthetic appearance, causing problems in terms of design, and lowering the commercial value.

This project was developed to improve these drawbacks, and will be explained below according to the embodiment shown in the drawings. 1 is a direct-mounted lighting fixture that is directly attached to the ceiling of a room, and is made of metal. A pair of sockets 1 on the bottom plate 2
Two straight fluorescent tubes 3, 3, which are attached via tubes 7, 17 and parallel to each other, a ballast (not shown),
a receiver 4 of a remote control device for lighting equipment mounted on the bottom plate 2 in the gap between the fluorescent tubes 3;
It is composed of a transparent cover 5 that covers these.

The receiver 4 receives the UHF band on/off instruction radio waves transmitted every time the operation button 7 of the transmitter 6 of the remote control device placed on the desk or the like in the room is pressed, and the fluorescent tube 3 , 3 lights up,
Lights can be turned off remotely.

In this receiver 4, a circuit board 8 receives the command radio wave and controls lighting and extinguishing of the fluorescent tubes 3, 3; . Protrusions 12, 12... for fixing the antenna rod are protruded in a straight line on this abutting part.
Further, a pair of attachment pieces 13, 13 are provided on the edge of the opening. 14 is the antenna rod fixing abutment 12;
12... by fixing it to the elongated side surface 1
An antenna rod installed in parallel along the lines 0 and 10 receives radio waves from the transmitter 6 and connects the fluorescent tubes 3
It is electrically connected to the circuit board 8 in the receiver 4 via the antenna lead wire 15.

This elongated housing 9 is arranged in the gap between the two straight fluorescent tubes 3, 3 in parallel with these tubes,
The mounting pieces 13, 13 are installed in the lighting fixture 1 by fixing them to the bottom plate 2 with screws 15, and in this case, the first and second reflective inclined surfaces 11a, 1
1b faces each of the two straight fluorescent tubes 3, 3, and reflects the light from these fluorescent tubes 3, 3 on these reflective inclined surfaces 11a, 11b to form an elongated housing 9. The bottom part of the transparent cover 5 is prevented from becoming dark, thereby preventing a shadow from being formed on the transparent cover 5.

Since the present invention was made as described above, even though the receiver is placed in the gap between the straight fluorescent tubes, the bottom part of the receiver is also sufficiently illuminated, and therefore the bottom part becomes dark. Therefore, the light-transmitting cover does not form a shadow, and the whole light-transmitting cover becomes bright.Therefore, it has a great effect in terms of design without detracting from the aesthetics. 1,
Since it is attached almost parallel to the part where the second reflective slope faces butt, the antenna rod receives sufficient light and does not get dark, and the antenna rod casts a shadow on the transparent cover. In addition, the signal can be reliably received no matter where the transmitter signal is transmitted, and the commercial value of the lighting equipment equipped with the receiver of the remote control device for lighting equipment will not be reduced. This has the effect of
