of fluorescent and incandescent lamps. Chemical decomposition of LED chips reduces luminous flux over life cycle as with conventional lamps. Commercial LED lighting products use semiconductor light-emitting diodes. Research into organic LEDs (OLED)‚ or polymer light-emitting diodes (PLED) is aimed at reducing the production cost of lighting products. Diode technology currently improves at an exponential rate. LED lamps can be made interchangeable with other types of lamps. Assemblies of high

night time‚ the LDR resistance is high and the alarm is in OFF state. When daylight is detected‚ the resistance goes low and alarm switches ON. It can also be switched off using a manual switch. This project can be effectively used for automatic lighting of bedrooms‚ hostels‚ streetlights‚ garden lamps etc to save power and reduce human intervention. It is of low cost and requires only a trivial amount of DC power to operate. 1 http://mskrao.weebly.com http://mskrao.weebly.com http://mskrao.weebly
