Description

technical field [0001] The invention relates to a driving system, in particular to an LED dimming driving system based on a filter amplifying triode voltage stabilizing circuit. Background technique [0002] With the development of society and the improvement of living standards, people's minds have also been fully liberated. Nowadays, people are very individualized, have their own unique insights into the cognition of objects, and have different needs for things. Similarly, the sensitivity to light is not necessarily the same. Moreover, due to the increasing abundance of electronic products, people's excessive eye use is becoming more and more serious, and the degree of damage to the eyes is different, and the sensitivity to light is also different. Most of the LED light sources currently on the market cannot be dimmed, so they cannot meet people's individual needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that mo...
