業性を向上するようにしたことを目的とする。[Detailed description of the invention] This invention is a radio-controlled lighting device that is attached to the bottom plate of the lighting device, is housed within the lighting device, and receives command radio waves from a transmitter to control the lighting and extinguishment of the lighting device. It is related to a receiver for a remote control device for use in a lighting device, and in particular, even if the bottom plate of the lighting device is made of metal, it is possible to prevent the reception frequency from shifting before and after installation to the lighting device, so that the receiver can The purpose is to simplify the adjustment work and improve workability.

大幅に悪くなるという欠点がある。 In other words, the receiver of this type of remote control device is adjusted in advance to ensure that it receives the UHF band command radio waves from the transmitter during assembly work, and is then incorporated into the lighting equipment, but the frequency used is
Since it is as high as 370MHz, if there is a metal or conductive object near the high frequency circuit, the reception frequency will change due to stray capacitance between the high frequency circuit and these metal or conductive objects, especially if the lighting equipment has a metal bottom plate. If so, the preset reception frequency will deviate significantly, making it impossible to receive command radio waves from the transmitter. Therefore, if you attach this receiver to the board of the lighting equipment in advance and store it inside the lighting equipment, and then adjust the reception frequency, the reception frequency will be adjusted accurately, but it will be very loud compared to the receiver. The disadvantage is that the entire lighting fixture must be handled, which greatly impairs assembly workability.

るものである。 In this receiver 4, reference numeral 8 denotes a printed circuit board that includes a high frequency circuit portion 9a for receiving the command radio waves and is equipped with a control circuit 9 for controlling lighting and extinguishing of the fluorescent tubes 3, 3.
A high frequency oscillation coil 10 is provided by etching. Reference numeral 11 designates a housing with an opening on the top surface for housing the printed circuit board 8. The housing 11 has a pair of mounting ears 12, 12 protruding from the edge of the opening, and antenna support rods 13, 13 protruding from the bottom surface, respectively. Reference numeral 14 denotes a receiving antenna installed on the antenna support rods 13, 13, which is connected to the high frequency circuit portion 9 of the control circuit 9.
a via a lead wire 15. 16

It is fixed by inserting it into the mounting holes 19, 19 and twisting the tip portion. Then, an adjustment screwdriver or the like is inserted into the adjustment hole 17 of the shield plate 16 of this printed circuit board 8, and the oscillation coil 20 is adjusted in advance so that the command radio wave from the transmitter 6 is stably and reliably received. Printed circuit board 8
is housed in the casing 11 and the lead wire 15 is connected to the receiving antenna 14, and then the mounting ears 12 of the casing 11 are attached to the metal bottom plate 2 of the lighting fixture 1 with the screws 21,
