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 and high-power DC LED lamps with dimming control, being characterized in integrating a transformer, an adapter or a power supply, a driver of a plurality of the high-power DC LED lamps, and a variable resistor comprising an adjusting element that is rotatable and adjustable and controllable through a wired or wireless way so as to control and adjust a current output to a high-power DC LED unit of each of the high-power DC LED lamps, thereby adjusting luminance and power consumption of each high-power DC LED unit of the high-power DC LED lamps.

2. The power supply of claim 1, wherein the high-power DC LED unit of each of the high-power DC LED lamps includes a plurality of the high-power DC LED units.
