Abstract

The invention provides a dimming circuit, a lamp component, a dimming system and a dimming method. The dimming circuit includes: a processing unit and a driving unit, wherein the input end of the processing unit is used for being connected with a central controller, the output end of the processing unit is electrically connected with the first input end of the driving unit, the second input end ofthe driving unit is used for being connected with a first power source, and the output end of the driving unit is used for connecting with M light source components in a lamp; the processing unit isused receiving dimming information sent by the central controller and is also used for acquiring target current ration information of the M light sources according to the dimming information and a preset ratio set; the driving unit is used for receiving the target current ratio information sent by the processing unit, and transmitting corresponding respective target dimming currents to the M lightsource components according to current provided by a first power supply and the target current ratio information. The dimming circuit, the lamp component, the dimming system and the dimming method allow lamps to be dimmed flexibly according to actual needs.

Description

technical field [0001] The invention relates to the technical field of dimming of lamps, in particular to a dimming circuit, a lamp assembly, a dimming system and a dimming method. Background technique [0002] With the gradual enhancement of people's awareness of energy saving and environmental protection, dimming lamps have been more and more widely used in daily life and work. figure 1 The structural schematic diagram of the traditional dimming system provided by the present invention, such as figure 1 As shown, the traditional dimming system includes: a centralized controller 11 and a plurality of lamps 12, each of which includes a high color temperature light source assembly and a low color temperature light source assembly. Among them, the centralized controller 11 usually uses two dimming lines to input voltages of different amplitudes to each lamp 12 to dim each lamp 12, and one of the dimming lines is used to adjust the low color temperature light source components...
