The problem effectively overcomes the problem that the ratio of the different color phosphor powders in the aforementioned patents and the process are difficult to control, that is, the red phosphor is used to replace the conventional red phosphor, and the light-emitting phosphor layer material is further simplified. The color material, such a design, can solve the problem that the mixing ratio of different colors and the process are difficult to control, and further control the wavelength of the single excitation light (ie, the wavelength of green light) of the light, and further, the case utilizes the red light] LED The red light emitted is mixed with the A-light and the light-adjusting two-color light, and the obtained white light color is better.
