Problems solved by technology

[0003] However, all LED lamps have control circuits and drive modules to convert the mains electricity into voltage and current suitable for LED lamps to drive LED lamps to emit light. This makes the cost of LED lamps relatively high and affects their wide-scale popularization.
Furthermore, the control circuit only has two states of turning on and turning off the light, which makes it difficult for the LED lamps to achieve a dimmable state. Even if there is a dimmable LED lamp, its dimming effect is not good

Abstract

The invention provides a control circuit. By connecting the AC power network through the first access terminal and the second access terminal, the LED lamp is directly driven to emit light through thealternating current, the control circuit includes a protection unit, a light emitting module, A low-frequency flash control unit and an electrostatic protection unit, an Output unit and an IC unit, comprising a regulating unit and an auxiliary regulating unit, The output currents of the control unit and the auxiliary control unit enter the IC unit, the control unit is used for controlling and adjusting the light brightness of the light emitting module, the auxiliary control unit is used for assisting the light brightness of the light emitting module and improving the compatibility between thecontrol unit and the IC unit.

Description

technical field [0001] The invention relates to a circuit, in particular to a control circuit for an LED lamp. Background technique [0002] Today's lamps on the market mainly include incandescent lamps, energy-saving lamps and LED lamps. Among them, the market share of incandescent lamps has declined due to shortcomings such as short life, poor stability and lighting comfort, and high power consumption. Because energy-saving lamps contain heavy metals such as mercury, when they are scrapped, the pollution to the environment is serious, which affects their wide-scale use. At present, LED lights have the advantages of energy saving, environmental protection, and long life, and widely occupy the main position in the lighting market. [0003] However, all LED lamps have control circuits and drive modules to convert the mains power into voltage and current suitable for LED lamps to drive the LED lamps to emit light. This makes the LED lamps expensive and affects their widespre...
