Abstract
An outdoor lamp capable of changing colors includes a support member, a lamp holder disposed on the support member, and an LED light module disposed in the lamp holder. The LED light module includes at least one PCBA (printed circuit board assembly) arrayed with a plurality of LED groups. Each of the LED groups is composed of at least one white/warm white LED and at least one RGB LED adjacent to each other. Each of the white/warm white LED and the RGB LED can emit light simultaneously or individually. When the RGB LED emits light to change colors, the luminous flux of the entire LED light module can be improved by the aid of the white/warm white LED, and a color gradient effect is generated.

An outdoor lamp capable of changing colors, comprising a support member, a lamp holder disposed on the support member and an LED light module disposed in the lamp holder, the LED light module including at least one PCBA (printed circuit board assembly) arrayed with a plurality of LED groups, the PCBA being electrically connected to an LED driver, characterized by:
- each of the LED groups being composed of at least one white/warm white LED and at least one RGB LED adjacent to each other, the LED driver driving and controlling each of the white/warm white LED and the RGB LED to emit light simultaneously or individually;
- wherein when the LED driver drives and controls the RGB LED to emit light in a fixed color manner or in a color-changing manner, luminous flux of the LED light module is increased through white light/warm white light emitted by the white/warm white LED.
