AUTOMATIC ILLUMINATION-REGULATING DEVICE FOR KEEPING ILLUMINATION CONSTANT

摘要: The utility model discloses an automatic illumination-regulating device for keeping illumination constant, which can adjust automatically the brightness of a lamp when table top intensity changes because that external light or electric voltage is unsteady to keep constant and invariant. also be used household lighting control public places applied in energy conservation devices, but not suitable controlling florescent lamps; controlled by silicon, triggering circuit silicon composed reception compensation amplification circuit, driving photoelectric coupling trigger circuit.
