The present invention provide a constant current and temperature compensation control device for outdoor spotlights used on laser stages which includes a single chip microcomputer, a triode or an field effect transistor, a laser LED light, a heating piece and a driving triode used for driving the heating piece. The benefits of the present invention include protecting the laser light from damage caused by power surge which results in no light or weakened light intensity, saving the cost of a specialized current limiting chip, making the green laser module work normally in extremely cold outdoor environment thus being more favorable to apply this device to mood creating lights of Christmastime.
