Abstract

A two-stage photo controlled circuit is disclosed. The two-stage photo controlled circuit is constituted by a photo sensing circuit, a comparing circuit, a switch circuit, a first driving circuit and a second driving circuit. The first driving circuit is always shorted to drive a loading. The second driving circuit is paralleled to the first driving circuit. The photo sensing circuit generates an electric signal based on the illumination of the environment. The comparing circuit compares the electric signal with a preset value, and generates a trigger signal based on the result. The switch circuit makes the second driving circuit to be shorted based on the trigger signal. Therefore, the loading can be driven by both the first driving circuit and the second driving circuit when the photo sensing circuit is triggered by the change of the illumination.
