Description

technical field [0001] The invention relates to the technical field of LED lamp equipment, in particular to a high-precision light control method for LED lamps with high control precision and less prone to misoperation. Background technique [0002] The photosensitive devices of the light control circuit mostly use photoresistors, phototransistors and other devices as light control detectors. The output of these devices is large, that is, the output current value of the same illuminance has a large deviation. The circuit mostly uses a voltage comparator to set a fixed threshold to control the switch of the light. The control accuracy is poor and it is prone to malfunction. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of poor control precision and prone to misoperation of the light control circuit in the prior art, and provide a high-precision light control method for LED lamps with high control precision and less p...
