The invention relates to an LED constant light current driving control method. The method is mainly realized via a light current calculating circuit, a light current reference circuit, a compensation network and a driving circuit. Compared with traditional constant current control and constant power control manners, influence of forward current on LED output luminous flux as well as influence of temperature on the LED output luminous flux is considered in the method, and LED constant luminous flux control or accurate light modulation control can be realized effectively. The method is simple and practical and can serve as a high-efficiency LED control strategy.
