Description

This application claims the benefit of CN202411629631X, filed with the Chinese Intellectual Property Office on Nov. 14, 2024, and entitled “CHIP LAMP BEAD AND LUMINAIRE.” the entire disclosures of which is incorporated by reference herein. TECHNICAL FIELD The present disclosure relates to the technical field of lamp beads, and particularly to a chip lamp bead and a luminaire. BACKGROUND ART Existing CHIP-type LED lamps mostly provide monochromatic light such as red, green, blue, warm white and white light, or multi-color light such as two-color and three-color light obtained by combining R, G, and B, and a lamp bead is packaged by compression-molding a monochromatic LED wafer with a transparent glue or a fluorescent glue. In a production process, an LED chip of each color needs to be separately packaged and then assembled, and position and connection of each chip also need to be precisely controlled, which makes the whole production process complicated, reduces production efficiency, and also increases production cost. There are shortcomings such as slow manufacturing, high cost, and complex production process for realizing simultaneous lighting of full color R, G, B, white light and warm white light in the same region. Moreover, in the prior art, it is difficult to integrate multiple colors (R, G, and B) and white light of different color temperatures (cool white and warm white) into the same lamp bead, and it is impossible to realize an iridescence function of a lamp string with full color R, G, B, white light and warm white light (RGBW/RGBCW) in the same lamp. SUMMARY In view of this, the present disclosure aims at providing a chip lamp bead and a luminaire, which can realize an integrated single-lamp light source, of which a full color system and multiple color systems of a single lamp are simultaneously controlled and emit light.
