A fluorescent LED light bar based on CSP or FC chips, comprising: a substrate integrated with several CSP or FC chips arranged in parallel, the outer periphery of the substrate is wrapped with an outer layer of phosphors, and the cross-section of the outer layer of phosphors is rectangular or Arc shape, etc. In this application, using the small size, high current, high reliability of the CSP or FC chip and its advantage of no wire bonding, after integrating the CSP or FC chip on the substrate, it is completely wrapped by the phosphor outer layer, Simplify the processing technology and bring the advantages of uniform lighting at the same time, control the distance between the chip light sources and the number of arrangements and the thickness of the wrapped fluorescent material, so as to achieve the purpose of uniform lighting. Compared with the existing uniform lighting scheme, the processing process is reduced. , which effectively saves costs and has good popularization. |
