[0002] A dimming power supply is a power supply device used to supply dimmable devices. It can provide an adjustable output voltage or current to meet the needs of dimming devices. Dimming power supplies are usually used to supply lamps and lighting systems that require dimming or brightness adjustment, such as LED lamps, fluorescent lamps, halogen lamps, etc. The working principle of a dimming power supply is usually to adjust the output voltage or current value to change the power output of the power supply device. In addition, dimming power supplies also have the advantages of low power and wide type compatibility.

[0003] The existing dimming power supply has its wiring terminals generally at both ends of the dimming power supply. After the wiring is completed at both ends of the dimming power supply, most of the wiring positions are not protected, making it inconvenient to perform functions such as waterproofing, dustproofing, and object contact prevention at the wiring position, making it inconvenient to ensure the safety of the wiring position during the use of the dimming power supply. For this reason, we propose a dimming power supply. Utility Model Content

The clamping block 203 matches the clamping groove 206 on the movable clamping block 205. The protective component 200 also includes a bottom support bar 208 fixedly installed on the outside of the wiring board 201.

[0026] Specifically, a dimming power supply is a power supply device for supplying dimmable devices. It can provide an adjustable output voltage or current to meet the needs of the dimming device. The dimming power supply is usually used to supply lamps and lighting systems that need to be dimmed or dimmed, such as LED lamps, fluorescent lamps, halogen lamps, etc. The dimming power supply also has the advantages of low power and wide compatibility.
