[0027] By arranging the pure white flip chip 5 and the warm white flip chip 6 in a circular design, 360° uniform light emission is achieved. In this way, the pure white and warm white chips are combined into a circular light-emitting surface. Whether they are lit individually or together, the light beam is uniformly distributed in a circular shape. At the same time, the principle of RGB color mode is based on additive color mixing, that is, to produce more colors by increasing the intensity of different colors of light. In this mode, each color (red, blue, green) has its specific intensity value. The combination of these values ​​produces rich colors. When the red light generated by the red light chip 4 is located on the periphery, while the green light generated by the green light chip 2 and the blue light generated by the blue light chip 3 are located in the center, their interaction and mixing will be more direct, thus affecting the final color performance. This layout makes the red more prominent, while the mixing of green and blue is more uniform, resulting in a more vivid and full color effect.
