Illuminating lamp energy-saving control device

The utility model provides an illuminating lamp energy-saving control device including an infrared control circuit, a light control circuit, and a photosensitive control circuit, the infrared control circuit includes a human body pyroelectric infrared sensor, a pyroelectric infrared sensing signal integrated circuit, a first triode, a coil of a first relay, and other peripheral circuits, the light control circuit consists of a fourteenth resistor, and normally open contacts of a first relay and a second relay, and the photosensitive control circuit consists of a second diode, a coil of a second relay, a fifteenth resistor, a photo-resistor, and a diode. The control device detects whether there has someone through the infrared control circuit; and meanwhile, the control device detects indoor brightness to control the closing of the light control circuit through the photosensitive control circuit, and therefore, the control device is simple in structure, safe and reliable, and can save electric power to a large extent.
