Description

[Detailed description of the invention] This invention relates to a remote control lighting equipment that can remotely control lighting equipment with a pull switch such as ceiling hanging lights and direct ceiling lights. Regarding antennas.

Hereinafter, the present invention will be explained based on the embodiment shown in the drawings. Reference numeral 1 is a ceiling-suspended fluorescent lamp, which is suspended from the ceiling surface by hanging chains 2, 2 and is supplied with power through a hanging ceiling 3. ing.

Reference numeral 4 indicates a fluorescent tube of this ceiling-hanging fluorescent lamp 1, 5 indicates a lighting device including a ballast and lighting tube for lighting this fluorescent tube 4, and 6 indicates a conventional device for switching the fluorescent tube 4 on and off. The well-known pull switch 7 is a metal drawstring made of a metal chain for operating the pull switch 6.

8 is a remote control receiver that controls the lighting device 5 to turn on and off the fluorescent tube 4 regardless of the pull switch 6; A receiving circuit 12 to which the antenna terminal 11 is connected via second antenna patterns 10a and 10b, and this receiving circuit 1
It has a control circuit 13 that controls the lighting device 5 with two outputs, and this antenna terminal 11 is connected to the base end portion of the metal drawstring 7 via a shielded wire 12, and A command radio wave for turning on and off transmitted from a remote control transmitter 13 placed on a desk or the like is received by the metal drawstring 7 and inputted to the receiving circuit 12, so that the fluorescent tube 4 can be turned on and off remotely. It is designed to be controlled.

The remote control type lighting equipment of the present invention is as described above, and in particular, the pull string of the pull switch that switches the lighting on and off is made of metal, and furthermore, it is equipped with a remote control receiver that remotely controls the lighting and extinguishing of the lighting. Since the antenna terminal of the remote control receiver is connected to the metal pull cord, the reception sensitivity will not decrease at all even if the remote control receiver is housed inside the light fixture body. Since it hangs further down, the distance from the remote control transmitter placed on a desk etc. is shorter, so even a remote control transmitter with a small transmitter output can turn on and off the lighting equipment. Can be controlled reliably.

Furthermore, according to this proposal, the appearance of the conventional pull switch is simply replaced by a metal one, and there is no need for a special antenna for receiving radio waves other than the pull cord, which improves the aesthetic appeal of the design. There is no damage to the product, and therefore there is no reduction in commercial value.
