The invention belongs to the technical field of semiconductor integrated circuits, and discloses an LED lamp, an LED color temperature adjustment control chip and a circuit. In the present invention, by adopting the LED color temperature adjustment control chip including the low-voltage detection module, the state output and the driving module, the low-voltage detection module alternately outputs corresponding detection signals according to the change of the output voltage, and when the output voltage is less than the preset value , the low voltage detection module outputs the first detection signal to the state output module, when the output voltage is greater than the preset value, the low voltage detection module outputs the second detection signal to the state output module; The signal is output to the corresponding state signal to the driving module according to the number of jumps of the second detection signal; the driving module drives a plurality of constant current chips according to the state signal to realize the control of the plurality of constant current chips, and the structure is simple and the cost is low. Furthermore, the problems of large volume and high cost in the existing LED color temperature adjustment control circuit are solved.
Description
technical field [0001] The invention belongs to the technical field of semiconductor integrated circuits, and in particular relates to an LED lamp, an LED color temperature adjustment control chip and a circuit. Background technique [0002] In recent years, LED lamps have been widely used as lighting power instead of traditional incandescent lamps, and with the improvement of people's requirements for LED lighting power and the development of LED technology, LED lighting power with adjustable color temperature has become a new development. trend. [0003] At present, the existing LED color temperature adjustment control circuit mainly controls the operation of the constant current chip through the color temperature adjustment control chip, so as to realize the color temperature adjustment control of the LED lamp. Wherein, the existing color temperature adjustment control chip includes a clock detection module, a noise suppression module, a state storage module and a drive ...
