The “All-in-One” LED includes 5 colors and white light as the primaries in a compact package of 7.0mm×7.0mm size (name as 7070H). It is the closest LED to a point light source but with rich and comprehensive spectrum mixing recipes. Each LED package is an individual light source that can achieve full-color functions. The “All-in-One” LED can reach a saturated color gamut in the CIE diagram and excellent white light with accurate chromaticity coordinates. The 7070H LED package with different colors/CCTs is defined as listed below.
Chip-on-Board
Compared to the “All-in-one” LED, the “Chip-on-Board” LED organizes different colors in a CoB style and is more flexible to define different layout designs with more color options. The whole “Chip-on-Board” is the unit light source that each color on it will be collocated with the adjacent to accomplish the spectra mixing. Different CCTs/colors are defined as the standards on the “Chip-on-Board” as listed below, with 2.0mm×2.0mm size.
Applied on the board, the colors can be mixed sufficiently after the optics or reflector thus the “Chip-on-Board” is the final point light source.
Comparison
The “All-in-One” and “Chip-on-Board” present different features thus they lead to different design paths. The different structure makes the optical, electrical and thermal designs differently, solutions would depend on the specific products accordingly.
