  • Patent number: 9923125
    Abstract: A method for improving optical performance of an LED light source, a light conversion filter obtained by using the method, and the corresponding LED light source. In the method, an LED chip is packaged by using a light wavelength conversion component, and the light wavelength conversion component is at least provided with two types of light conversion filters with light excitation performance. With the excitation of light rays that are sent by the LED chip and have wavelengths in an ascending order, sent light rays show an opposite change tendency in light intensities of light rays after the light rays are converted by the two types of light conversion filters. The method can reduce the discrete degree of chroma distribution of light transmitted by the LED light source, and improve the defect-free rate of the LED light source.
