Another innovation in LED lighting source products:  3D COB

 


3D COB integrated solution can be used with dimensional lighting or plane lighting remote phosphor solutions. Compared to single or group LED packages, where phosphor is placed very close to the die and receives near range concentrated light source stimulation, the remote phosphor used in 3D COB are is located further away from the die and excited by long range light source. The advantages provided by such an arrangement include excellent lumen maintenance, small differences in hot-cold factor, and slight color shifts. In addition, by applying remote phosphors in GPI’s high luminous efficacy Match LED, it is also able to get improved color uniformity and diverse color temperature options. For luminarie manufacturers, these technological advantages open up a lot of opportunities for luminaire manufacturers to create more  flexible light fixture designs.


 

3D COB’s core light source employs the patented blue light Match LED component, The component is constructed on the foundation of AT chips, and includes the following features: wire-bond free, compact arrangement, low thermal resistance, and high light efficiency.
