Blue-ray LED driving system with adjustable brightness

The invention discloses a blue-ray LED driving system with adjustable brightness, characterized by mainly comprising a control chip U, and a light adjustment control circuit, a reference correction circuit, a slope compensation circuit and a logic buffer circuit which are connected with the control chip U; the reference correction circuit is connected with the logic buffer circuit; and the light adjustment circuit is connected with the logic buffer circuit. The system provided by the invention can eliminate or attenuate external electromagnetic interference, and locks voltage and current for limitation, thus the voltage and current keep steady; and when in actual use, the anti-electromagnetic interference capability of the system is improved by more than 1.5 times over the existing driving system, can output stable driving current, meanwhile can accurately adjust the brightness of an LED light, and can effectively ensure the stability of the brightness of the blue-ray LED light. Meanwhile, the load capacity of the system provided by the invention can be effectively enhanced.
