Abstract

The invention relates to a light modulation apparatus. The light modulation apparatus comprises a positive electrode output terminal, a negative electrode output terminal, a rectification filtering module and a light modulation driving module, the positive electrode output terminal is used for being connected to a positive electrode of an illumination light source, the negative electrode output terminal is used for being connected to a negative electrode of the illumination light source, a first output terminal of the rectification filtering module is separately connected with an input terminal of the light modulation driving module and the positive electrode output terminal, a second output terminal of the rectification filtering module is connected with a grounding terminal, a first output terminal of the light modulation driving module is connected with the negative electrode output terminal, the light modulation apparatus also comprises a shunting circuit, a first terminal of the shunting circuit is connected with the negative electrode output terminal, a second terminal of the shunting circuit is connected with the grounding terminal, the impedance of the shunting circuit is R(0<R<P / (I*I)), wherein P is a preset power threshold, and I is a current in an illumination light source loop corresponding to the preset power threshold. By employing the apparatus, the problem of flickering of the conventional light modulation lamp during low brightness can be solved.

Description

technical field [0001] The invention relates to the technical field of lighting control, in particular to a dimming device and a dimming lamp. Background technique [0002] The dimming device is a device that can adjust the brightness of the light, and can be applied to the dimming of various lamps such as incandescent lamps and LED lamps. [0003] Generally speaking, there will be slight fluctuations in the dimming signal output by the dimming device. The current common dimming device is used for dimming. When the brightness of the light source is adjusted to a lower brightness, for example, when using more stages When the multi-level dimming device adjusts the luminous brightness of the light source to a lower brightness level, or when the stepless dimming device is used to adjust the luminous brightness of the light source to close to zero, the light source caused by the fluctuation of the dimming signal The brightness change of the LED is relatively obvious, and the hum...
