A remote lighting control system is for remote lighting control of a plurality of discharge lamps. This system has the installed electronic ballasts of each discharge lamp. Each electronic ballast has a transceiver and a controller, the transceiver exchanges control information with the controller. The control command contains the identifiable information to specify one of a plurality of electronic ballasts. When the transmitter is received the control command, the transceiver transfers the received control command to other electronic ballasts further. Moreover, if the control command is the one that the identifiable information specifies own ballasts, the control information based on the received control command is send to own controller, and the controller control the discharge lamp. According to this system, when a lot of lamps was arranged the factory etc. comparatively widely, the user's remote control is not limited to the narrow scope.

Remote lighting control system

Even though an antenna apparatus is low profile to have a height of not more than 70 mm, sensitivity is maximally suppressed from being deteriorated. In an antenna caseprojecting from a vehicle in a height of not more than 70 mm, an antenna circuit boardon which an antenna pattern is formed is uprightly arranged and an amplifier circuit boardwhich amplifies a received signal output from the antenna circuit boardare housed. In the antenna circuit board, an antenna coil to resonate the antenna pattern in an FM waveband is inserted between the antenna pattern and a feeding point. Therefore, a low-profile antenna pattern having a length which is about 1/20 a wavelength of an FM broadcast resonates the FM band.
