Abstract

The invention relates to the technical field of LED lamp filtering, in particular to a following dimming anti-short-circuit protection ripple removing circuit, which comprises a power source, a ripple removing circuit and an LED lamp, wherein the ripple removing circuit is connected between the power source and an LED, and comprises a ripple sampling circuit, a power frequency ripple removing circuit and a protection circuit. According to the invention, a constant current source with power frequency ripples generates sine wave signals through the filtering characteristic of aluminum electrolysis on alternating current, the sine wave signals achieve the effect of removing the power frequency ripples through sine conduction, and the characteristic that forward voltage drop of two diodes is higher than that of a source electrode and a drain electrode when a triode works is utilized; and during normal work, current passes through the triode to remove power frequency ripples, clamping protection is carried out on the triode during output short circuit, the protection function is pioneered in the industry, and a great role is played in promoting LED green lighting, healthy lighting and eyesight protection.

Description

technical field [0001] The invention relates to the technical field of LED lamp filtering, in particular to a follow-up dimming anti-short circuit protection ripple removal circuit. Background technique [0002] At present, the LED lighting industry has also risen from the pursuit of light efficiency, energy saving and cost to the demand for light quality, light health, light biological safety and light environment. Especially in recent years, problems caused by LED stroboscopic flicker, human rhythm disorder, and retinal damage have become increasingly prominent, making the industry realize that the popularization of healthy lighting is urgent. All in all, healthy light can create a warm and comfortable light environment for consumers, giving people a feeling of comfort and natural relaxation. Flicker-free lighting plays an important role in preventing myopia and protecting eyesight for young students. [0003] For this purpose, a anti-short-circuit protection ripple circ...
