The main factors affecting the luminous efficiency of LED 1. The size of the phosphor particle size If the particle size is relatively large, it will directly reduce the light intensity and the difficulty of dispensing (easy to precipitate). Based on the current use of phosphors, the fatal injuries of domestic phosphor manufacturers are also here. The width of the excitation spectrum of the phosphor also affects the light efficiency of the light (whether blue light can fully excite the phosphor).

2. Excitation spectrum of phosphor
3. The anti-aging properties of phosphors This parameter directly affects the life of white LEDs.
4. Anti-aging property of epoxy resin This parameter also directly affects the life of white LED
5. The reflection efficiency of the lead frame (bracket) or the reflective cup of the substrate slide area This is also a key factor that affects the light intensity. There will be a 20% gap between good and bad, and the quality of the level will have an impact.
