ABSTRACT:
This invention provides an optically controlled dimmer (optically controlled light adjustment device), more particularly, an optically controlled dimmer having a mechanism capable of detecting light reflected from an object in a short distance and to cause a driving circuit to perform ON-OFF action and to adjust the intensity of light in several stages. The mechanism includes an ultra red ray transmitter to perform the control. A transmitter and a receiver are disposed in parallel in a recess of a casing having a panel. The panel has one hole for transmitting control signal light, and another hole for receiving reflected signal light. The dimmer can be activated by blocking the signal light transmitted from the dimmer by hand, to produce a reflected signal light to be received by the receiver. The received reflected signal light is reformed by a stage control circuit and a switching circuit to perform ON-OFF actions. As a result, the intensity of light is controlled in stages.
