Integration of microwave sensor into low cost indoor LED lamp — Element of smart lighting system

Energy saving importance is growing year-to-year and effective lighting is considerable part of overall consumption reduction. Modern light sources (LED based lamps) are much less consuming than traditional ones. Furthermore, the saving can be increased, by implementing smart lighting control systems over theses lamps. High initial costs set investment bounds on wide use of systems of this kind. The main elements that give LED lamp smart functionality are: 1) dimmable driver; 2) communication module; 3) sensor/s (ambient light, movement, gas etc.); 4) controller. This paper gives the insight on cost reduction by integration of microwave motion sensor in LED lamp to build a smart system.
