Document Type and Number:
WIPO Patent Application WO/2017/107080
Kind Code:
A1
Abstract:
Disclosed is a four-color control LED lamp, characterized in that the LED lamp comprises a rectifying circuit, a constant-current control circuit, an MCU control circuit, and an LED series circuit, the rectifying circuit being connected to the constant-current control circuit, the constant-current control circuit being connected to the LED series circuit, the MCU control circuit being connected to the LED series circuit, and a filter circuit being arranged between the rectifying circuit and the constant-current control circuit; and the LED lamp further comprises a first voltage stabilizing circuit and a second voltage stabilizing circuit, the constant-current control circuit comprising a first constant-current control circuit, a second constant-current control circuit, a third constant-current control circuit, and a fourth constant-current control circuit that are connected, respectively, in series to a red LED series circuit, a blue LED series circuit, a green LED series circuit, and a yellow LED series circuit. The working condition of the LED lamp is not affected too much by temperature, ensuring the service life of the LED lamp; in addition, the LED lamp is not affected too much by voltage fluctuations, and the LED luminance of several kinds of colors is uniform in distribution and stable, improving the quality of the LED lamp.
