DESIGN OF LAMP LIFE TEST INSTRUMENT BASED ON WIRELESS COMMUNICATION

摘要

This paper put forwards an instrument for lamp life test, and elaborates the overall design scheme, key device types, hardware circuit design and host machine programming of the instrument. The instrument contains four illuminance sensors and one temperature sensor which can measure illuminance of the lamp lighting and environment temperature in the instrument body. The measure data can be transmitted to PC via the wireless transceiver modules for real-time monitoring. Based on measure data the lumens depreciation curve is plotted and reckons the life of the lamp.
