LIGHT-RECEIVING MODULE FOR INFRARED-RAY REMOTE CONTROL SIGNAL AND INFRARED-RAY REMOTE CONTROLLER LIGHTING FIXTURE

摘要

PROBLEM TO BE SOLVED: To provide a rationalized light receiving module for infrared-ray remote control signal and the infrared-ray remote controller lighting fixture. ;SOLUTION: A light-receiving element 3 to receive an infrared-ray remote control signal 2 is mounted on a board 1, an optical filter 4 is mounted in front of the light-receiving element 3, and a body 5 to which the element 3 and the filter 4 are molded with a synthetic resin is provided to the light- receiving module M for an infrared-ray remote control signal. The body 5 has band pass characteristics that is comparatively board enough to pass wavelength of the infrared ray remote control signal 2, and the optical filter 4 has comparatively sharp band pass characteristic whose transmission center wavelength is almost in matching with the wavelength of the infrared-ray remote control signal. The light-receiving module M is installed together with a fluorescent lamp 16 on the bottom of a lighting fixture main body 17, that is all covered with a translucent glove 18.;COPYRIGHT: (C)1999,JPO
