Encapsulating composition and light emitting device
2014
An encapsulating composition for a light emitting device includes a transparent resin, a plurality of light scattering particles distributed throughout the transparent resin and having an average particle size ranging from 190 nm to 450 nm, and a plurality of phosphor particles distributed throughout the transparent resin. The invention further provides a light emitting device includes the encapsulating composition and a light emitting diode that is encapsulated by the encapsulating composition. The light emitting device may achieve an effect of reducing the amount of the phosphor particles when not changing the brightness of the light emitting device by comprising the light scattering particles with a particular average particle size.
