Description

technical field [0001] The invention relates to a novel integrated semiconductor light source, which belongs to the application field of semiconductor lighting. Background technique [0002] As a new type of semiconductor lighting source, LED light source has the characteristics of excellent energy saving and environmental protection, low cost, long life and small size, so it has been widely researched and applied in the fields of lighting and display. In recent years, with the continuous improvement of people's requirements for light quality and the diverse needs for light source selection in different application scenarios, more light colors and high-quality light sources are needed to meet the growing lighting needs in the future. [0003] The existing mainstream LED lighting sources are mainly prepared by exciting yellow phosphor powder with LED blue light (B) chips. The red light (R) and green light (G) generated by the excitation are mixed with the remaining blue light...

AI Technical Summary

Problems solved by technology

However, the color temperature of the existing LED lighting source is fixed, and it is mainly concentrated in the range of white light color temperature or single-color lighting. For other light sources of any color due to the limitation of the light-emitting method, it is very scarce. Therefore, for scenes that require specific color lighting, now Mainstream light sources are no longer sufficient

[0004] In order to obtain an arbitrary color light source, some studies have used short-wavelength chips to excite red, green, blue, and yellow phosphors, but the resulting light source has low luminous efficiency and large color difference; or learn from the principle of LED display screens to mix light through red, green, and blue chips Realized, but need supporting equipment and software, difficult to realize, high cost

[0005] At the same time, the light-emitting units of the existing lighting sources are unevenly distributed, and the spacing is large, there is a serious glare problem, and the real surface light effect cannot be achieved, so it cannot meet the application in high-end scenes
