Abstract

The invention discloses an adjustable three-channel high-power LED (light-emitting diode) drive circuit which comprises a blue light access L1, a red light access L2, a green light access L3, a variable potentiometer R1, a variable potentiometer R2, a variable potentiometer R3, a current-limiting resistor R4, a current-limiting resistor R5, a filter capacitor C1, a filter capacitor C2, a filter capacitor C3 and a three-channel driver chip U1, wherein the variable potentiometer R1, the variable potentiometer R2 and the variable potentiometer R3 are used for controlling the on or off of the blue light access L1, the red light access L2 and the green light access L3 respectively; when the value of resistance of one variable potentiometer is minimum, the corresponding light access is off and current dose not pass through the light access; when the value of resistance of one variable potentiometer is higher than the minimum value, the corresponding light access is on, current passes through the light access, and the light access works and emits light. According to the embodiment of the adjustable three-channel high-power LED drive circuit, light dimming and color modulation of LED single-color light combinations can be simplified.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an adjustable three-channel high-power LED drive circuit. Background technique [0002] With the continuous development of LED lamp technology, LED lamps are not only used in more and more quantities, but also in a wider range of applications. In places where colorful display and lighting are required, it is too expensive to use a professional color LED display, and to combine LED monochromatic light, although the cost is low, the dimming and color adjustment are very cumbersome. Contents of the invention [0003] The embodiment of the invention discloses an adjustable three-channel high-power LED driving circuit, which is used for simplifying the light adjustment and color adjustment of LED monochromatic light combination. [0004] An adjustable three-channel high-power LED drive circuit, including: [0005] Blue light path L1, red light path L2, green light path...
