Abstract :
Traditionally halogen cycle lamps have been used for outdoor and industrial lighting. But actually low power halogen cycle lamps are used for merchandise and home lighting due to their size, no lumen depreciation and color rendering. Normal supply equipment for low power halogen cycle lamps are 50 Hz transformers. A very robust and low cost high frequency supply system for low power halogen cycle lamps based on a self-oscillating half bridge inverter is described in this paper. With respect to a 50 Hz transformer, weight and size have been reduced significantly for the same output luminous flux and input power. Power factor correction is carried out too. Moreover the design is simple, reliable and flexible
