THE ADVANCED DESIGNING OF LED DRIVER WITH THE DIFFUSIONAL ACCOMMODATION OF CURRENT SENSING TECHNOLOGY WITH OPEN LOOP PWM FOR STREET LIGHTING.

The High Brightness LEDs for street lighting has gained popularity in street lighting owing to energy efficiency and the long life. The amalgamated feature of brightness and the dimming solutions makes it equally adoptable in outdoor lightings. The street lighting utilizes the power supply from the lines. The invent of renewable energy resources for appliances and illumination systems highlights the usage of solar system for lighting and heating systems. The solar photovoltaic panels are most featured solutions. The standalone PV systems require the designing knowledge of electrical, thermal and optical properties of LEDs. These parameters allow the development of driver system for design of the luminaire. Different strategies have been proposed for driver circuits to provide stable characteristics. The selection of Drivers is dependent on various factors like, energy efficiency, cost effectiveness, operation and maintenance, losses associated with the components and the assembly
