Description

[Detailed description of the invention] This invention is a radio-controlled lighting device that is installed on the bottom plate of a lighting device, is housed within the lighting device, and receives command radio waves from a transmitter to control the lighting and extinguishing of the lighting device. The present invention relates to a receiver for a remote control device for appliances, and particularly relates to a receiver in which a receiving antenna rod is removable from a receiver housing so that it can be easily installed in a lighting appliance.

In other words, the receiver of this type of remote control device has an antenna rod outside the receiver housing that receives the command radio waves from the transmitter, but since this antenna rod is longer than the housing, it cannot be placed inside the lighting fixture of the housing. There is a risk that the antenna rod may get in the way when storing the antenna, making the storage process troublesome.

This proposal eliminates the above drawbacks and improves assembly efficiency by making the antenna rod removable and easily attachable to the receiver housing.The following is based on the embodiment shown in the drawings. To explain the main idea, 1 is a direct-mounted lighting fixture that is attached directly to the ceiling of a room, and three fluorescent tubes 3, 3, 3 and a ballast (not shown) are attached to a metal bottom plate 2. At the same time, a receiver 4 of the remote control device of the present invention, which has an elongated shape, is installed between these fluorescent tubes 3, 3, and 3 in parallel with the tubes, and is covered with a light-transmitting cover 5.

Reference numeral 6 is a transmitter of a remote control device placed on a desk or the like in the room, and each time the operation button 7 is pressed, it transmits a turn-on/light-off command radio wave in the UHF band of 370 MHz, and this transmitted command radio wave is received by the receiver 4 and lights up the fluorescent tubes 3, 3, 3,
Lights can be turned off remotely.

In this receiver 4, 8 is a circuit board that receives the command radio wave and controls lighting and extinguishing of the fluorescent tubes 3, 3, 3, and 9 is made of synthetic resin and has an opening on the top surface to accommodate this circuit board 8. In the receiver housing, the bottom surface of the housing 9 has first and second inclined bottom surfaces 10a, which are formed so as to abut each other and form a downward mountain shape.
10b and the first and second inclined bottom surfaces 1
At the abutting portions of 0a and 10b, there are first protrusions 12, 12 for antenna fixing having holding holes 11, 11 and second protrusions 1 for antenna fixing having grooves 13, 13.
4 and 14 are provided alternately and protruding in a straight line,
Further, a pair of attachment pieces 15, 15 are provided on the edge of the opening. An antenna lead wire 16 is connected to the circuit board 8 and has its tip led out from the insertion hole 17 of the housing 9, and has a terminal fitting 18 at its tip.

Furthermore, 19 is an antenna rod made of steel wire that receives the command radio wave, and this antenna rod 19 is formed to be longer than the side length of the elongated shape of the receiver housing 9. 1,
The holding hole 11 of the second protrusion 12, 12, 14, 14,
11 and concave grooves 13, 13 alternately and are fixedly inserted, and one end thereof is fitted into the terminal fitting 18, thereby connecting to the circuit board 8 via the antenna lead wire 16.

Then, connect the antenna rod 19 to the antenna lead wire 1.
6, and with the receiver housing 9 without the antenna rod 19 placed between the fluorescent tubes 3, 3 parallel to the tubes, attach the mounting pieces 15, 15 to the bottom plate 2 with the screws 20. to fix the receiver housing 9 to the bottom plate 2, and then attach the antenna rod 19 to the first and second protrusions 12, 12, 14, 14 for fixing the antenna.
By fixing the antenna rod 19 to the terminal fitting 18 of the antenna lead wire 16, the receiver housing 9 with the antenna rod 19 attached can be housed in the lighting fixture 1. ing.

The present proposal is as described above, and in particular, the antenna rod of the receiver of the remote control device built into the lighting equipment is made removable, so after the receiver housing is stored inside the lighting equipment with the antenna rod removed. The antenna rod can be attached to the receiver housing, greatly improving assembly work efficiency. Furthermore, since the antenna rod is placed apart from the bottom of the receiver housing, it can accurately receive command radio waves from the transmitter, and is a remote control device for lighting equipment that can accurately turn on and off the lights. can be obtained.
