WHITE-LIGHT LED MODULES
First Claim
1. A white-light LED module, comprising:
- a substrate, and a red-light LED chip string, a blue-light LED chip string, and a green-light LED chip string arranged on the substrate, wherein the red-light LED chip string, the blue-light LED chip string, and the green-light LED chip string are connected in parallel, a number of blue LED chips within the blue-light LED chip string equals to the number of green LED chips within the green-light LED chip string, the number of red LED chips within the red-light LED chip string is as double as the number of blue LED chips and the green LED chips;
two pins, two ends of the red-light LED chip string, of the blue-light LED chip string, and of the green-light LED chip string respectively connect to one corresponding pin;
at least one reflective wall surrounding the red-light LED chip string, the blue-light LED chip string, and the green-light LED chip string, wherein the substrate comprises a curved surface such that at least a portion of light beams emitted from the red LED chips, the blue LED chip, and the green LED chip are reflected back by the reflective wall.

Abstract
A white-light LED module is disclosed. The white-light LED module includes a substrate, and a red-light LED chip string, a blue-light LED chip string, and a green-light LED chip string arranged on the substrate. The red-light LED chip string, the blue-light LED chip string, and the green-light LED chip string are connected in parallel. A number of blue LED chips within the blue-light LED chip string equals to the number of green LED chips within the green-light LED chip string. The number of red LED chips within the red-light LED chip string is as double as the number of blue LED chips and the green LED chips. In this way, the light mixture performance of the red, green and blue LED chips may be enhanced.
