ABSTRACT
The paper systematically introduces the wireless light adjustable LED lamp development application field and design research significance. The single-chip microcomputer control technology of wireless communication technology, industry, LED control technology, puts forward a set of low cost, low power consumption, high reliability, high efficiency of wireless adjustable light, LED lamp design scheme.
A control scheme adopted AT89C2051, low cost, the core of wide application, developing difficulty is low. Wireless control using mature 315M band, and through the circulation encoding guarantees the reliability of communication. Supporting tube using new power LED, small volume, low power consumption, green environmental protection, long life, strong, can be controlled at any level of brightness.
The scheme design of lamps and lanterns, remote control, regulation of light intensity is more than 10 meters, high grade, adjusting range in using 0.5 256 earthen LED circumstance, total power than 0.7 watts. The test, control response time may not exceed 50 milliseconds, service life is over 10000 hours, meet the civil and industrial lighting needs.
