Problems solved by technology

[0002] Due to the advantages of high efficiency, energy saving, environmental protection, long life, and fast response speed of LED lamps, in the actual application of traditional LED drivers, due to the defects of the control system or control circuit, the LED lamp beads often fail because they are turned on. The instant cannot withstand the impact of a large current surge and cause burnout. When starting, the wire carries a large current and the light attenuates. It is basically not compatible with the intelligent control signal. At the same time, the LED lamp bead reaches the best brightness in an instant. negative impact on the senses

Description

technical field [0001] The invention relates to the technical field of architecture, in particular to an LED post-stage multi-control eye-relieving high-brightness drive circuit. Background technique [0002] Due to the advantages of high efficiency, energy saving, environmental protection, long life, and fast response speed of LED lamps, in the actual application of traditional LED drivers, due to the defects of the control system or control circuit, the LED lamp beads often fail because they are turned on. The instant cannot withstand the impact of a large current surge and cause burnout. When starting, the wire carries a large current and the light attenuates. It is basically not compatible with the intelligent control signal. At the same time, the LED lamp bead reaches the best brightness in an instant. The senses are negatively affected. [0003] [3] Therefore, it is necessary to improve the existing LED control circuit. Contents of the invention [0004] The invent...
