Abstract

A power supply with dimming control for a high-power DC LED lamp is provided. Particularly, a variable resistor is provided to a circuit of the high-power DC LED lamp for changing a current supplied to a light-emitting unit of the high-power DC LED lamp, thereby adjusting luminance (brightness) and power consumption (consumed watts) of the high-power DC LED unit of the high-power DC LED lamp. The variable resistor is provided to a driver, transformer, adaptor or power supply of the high-power DC LED lamp in a built-in manner or a remotely connected manner

Claims

1. A power supply with dimming control for a high-power DC LED lamp, being characterized in integrating a transformer, an adapter or a power supply 1, or a driver 2 of the high-power DC LED lamp into a whole, and providing a variable resistor 3 that serves to control and adjust a current output to a high-power DC LED unit 41 of the high-power DC LED lamp 4, thereby adjusting luminance and power consumption of the high-power DC LED unit 41 of the high-power DC LED lamp 4.

2. The power supply of claim 1, wherein the high-power DC LED lamp 4 includes one or more said high-power DC LED lamps 4.

3. The power supply of claim 1, wherein the high-power DC LED unit 41 of the high-power DC LED lamp 4 includes one or more said high-power DC LED units 41.

4. The power supply of claim 1, wherein the variable resistor 3 is an adjusting element which is rotatable and adjustable and controllable through a wired or wireless way so as to control and adjust an output current thereof for the high-power DC LED unit 41 to use.

5. The power supply of claim 1, wherein the variable resistor 3 is provided to the transformer, adapter or power supply 1, or driver 2 in a built-in manner or a remotely connected manner.
