Specifically how to realize below in conjunction with description of drawings the utility model.

The specific embodiment

A kind of intelligent power saving illuminator, comprise power supply and LED lighting circuit in the circuit structure, pyroelectric infrared detector 2 and light-sensitive element 3, control circuit 4 and the led drive circuit 5 that to survey human body have been set up in the illuminator, pyroelectric infrared detector 2 is gathered the light intensity signal of human infrared signal, light-sensitive element 3 collections, more than the two output connect control circuit 4, control circuit 4 output control signals are sent to led drive circuit 5, and led drive circuit 5 output drive signals connect LED lighting circuit 6.

Above-mentioned pyroelectric infrared detector 2 adopts Fresnel optical filtering wafer, Fresnel Lenses, pyroelectric sensor, MP01 chip and the supporting overlap joint of peripheral circuit.

Above-mentioned light-sensitive element 3 adopts photo resistance to WR1, WR2.

Above-mentioned control circuit 4 comprises A/D conversion chip ADC0832, single-chip microcomputer 89C55, D/A conversion chip DAC7266 and peripheral matched element, give single-chip microcomputer 89C55 after the human infrared signal that A/D conversion chip ADC0832 reception photo resistance is gathered the light intensity signal and the pyroelectric infrared detector 2 of WR1, WR2 collection, the processing, single-chip microcomputer 89C55 output control signal is delivered to led drive circuit 5 after D/A conversion chip DAC7266 processing.

Above-mentioned led drive circuit 5 comprises the bypass channel that exchanges that thyratron Q, resistance R 1 and capacitor C 1 form, and the control signal after the base stage reception control circuit 4 of thyratron Q is handled realizes brightness regulation to LED lighting circuit 6 by changing self internal resistance.

Above-mentioned LED lighting circuit 6 is the LED lamp string of one group of parallel connection, the direct current signal after the power supply integrated package AP-2B320 in the anode reception power-supply circuit 1 of LED lamp string handles.

The utility model utilizes light intensity signal and human infrared signal in light-sensitive element 3 and the pyroelectric infrared detector 2 real-time sensing chamber when concrete the use.When indoor mistake is bright, can reduce the power output of LED lighting circuit 6 automatically by led drive circuit 5, i.e. brightness; When indoor mistake is dark, can heighten the brightness of LED lighting circuit 6 automatically by led drive circuit 5, and the benchmark light intensity signal can pass through single-chip microcomputer 89C55 and supporting program setting.The adjusting of LED lighting circuit 6 brightness changes the internal resistance of source by thyratron Q and realizes, adds resistance R 1 and carries out the current stabilization adjusting with the bypass channel that exchanges that capacitor C 1 is formed, and makes the output of LED lighting circuit 6 more steady.
