The invention relates to a voltage control device. The voltage control device comprises a power supply module, a constant-current control module and a stroboflash-eliminating and light-emitting module; the stroboflash-eliminating and light-emitting module comprises a light-emitting module and a stroboflash-eliminating module; the power supply module is connected with the constant-current control module and the stroboflash-eliminating and light-emitting module and is used for supplying power to the constant-current control module and the stroboflash-eliminating and light-emitting module; the constant-current control module is connected in series or in parallel with the stroboflash-eliminating and light-emitting module and is used for improving the power factor of the light-emitting module and keeping the power factor constant; and the stroboflash-eliminating module is connected in series or in parallel with the light-emitting module and is used for eliminating the stroboflash of the light-emitting module. According to the voltage control device of the invention, the constant-current control module and the stroboflash-eliminating module are arranged in the light-emitting module, so that the power factor of the light-emitting module can be improved, it can be ensured that the stroboflash of the light-emitting module is reduced, and the visual experience of a human body is improved.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a voltage control device. Background technique [0002] With the development of social economy, more and more LED products appear in people's life and production. Among them, the linear full-voltage constant-current control power supply can ensure constant current and stable operation of lamps and lanterns, and has been widely used. [0003] However, there are serious deficiencies in the existing linear full-voltage constant-current control power supplies or finished lamps on the market, for example, the products do not have the rigid index of high PF (Power Factor, power factor), or the light source emitted by the LED has serious frequency Flickering may cause eye fatigue or cause eye damage, resulting in poor visual experience for the human body. Contents of the invention [0004] Based on this, it is necessary to provide a high PF in the prior art, or the light ...
