This circuit board usually includes one or more dimming controllers that receive external inputs (such as analog signals, digital signals, or touch sensing) and adjust the current or voltage in the circuit accordingly, thereby achieving precise control of the brightness of the light source.

[0003] Existing dimmable circuit boards usually rely on natural heat dissipation or simple heat dissipation design of the circuit board itself to dissipate heat.

[0011] Preferably, a plurality of springs are equidistantly and fixedly connected inside the slide groove, and ends of the springs are fixedly connected to side walls of the slide block.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] 1. The installed flame retardant board can effectively slow down the burning speed or even prevent the burning when the dimmable circuit board encounters high temperature or fire source, thereby improving the safety of the dimmable circuit board. The operator then installs the board on the lower end of the dimmable circuit board so that the upper ends of multiple heat sinks fit with the lower end of the dimmable circuit board. By designing the heat sink under the dimmable circuit board, the heat on the dimmable circuit board can be more effectively dissipated into the air, reducing the working temperature of the dimmable circuit board. The motor drives the rod body to rotate, and the rod body drives the blades to rotate, thereby accelerating the air flow, taking away the heat on the heat sink, reducing the working temperature of the dimmable circuit board, thereby improving the heat dissipation performance of the dimmable circuit board, and avoiding the dimmable circuit board from being damaged due to excessive temperature.

After the dimmable circuit board is repaired, when the plate needs to be installed, the operator manually pulls the card block to make the card block contact with the card slot. At this time, the slider is pulled by the elasticity of the spring, so that the slider drives the card block to slide, and the card block slides into the inside of the card slot, so that the plate is quickly installed on the lower end of the dimmable circuit board, which is convenient for disassembly and assembly of the plate.
