Design and Application of High-Power LED Drive and Control Circuits

Abstract:

LED (light emitting diode) is a solid luminescent source of fairly wide uses, a type of electronic components capable of transforming electric energy to luminous energy, which, emitted from LED, is highly centralized and strongly directive. LED can be driven simply by low-voltage direct current. This paper chiefly introduces the actualization of drive circuits by the constant current pattern, and proposes a type of high-power LED constant current drive solutions based on the constant current drive circuit PT4115. This drive circuit is simple, highly efficient and cost effective, suitable for the market demand of solar energy products.
