The Design of Sound and Light Controlled Corridor LED Lamp Based on Double Integration Detection

The design of a high-sensitivity LED lamp with low standby consumption, sound and light controlled type based on the micro-power consumption characteristic of MK6A12P is presented in this paper. The standby power consumption is less than 0.07W. And the problem of the light sense unit influenced by the change of the supply voltage is solved by the design of double integration detection circuit, thereby, the detection accuracy of brightness is improved. The service life of LED lamp is greatly prolonged with constant current drive. It is proved by the experiment that the LED lamp has the advantages of simple circuit structure, high operation stability and high cost performance.
