DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic opening/closing device capable of detecting ambient brightness and temperature and the approach of an object, and automatically opening and closing a load path under a desired combination of these two conditions.

All types of flashers operate reliably depending on the brightness of the surrounding area, but if such flashers are used for street lights, for example, the surrounding area will be dark (even if there are no people passing by) at night. The fatal drawback is that the lights are always on, which increases unnecessary power consumption and wastes energy.
