Abstract:
1. A light emitting diode comprising: a reflective cup comprising a bottom and a sidewall extending from the bottom, the sidewall comprising an inner reflective surface; an LED chip received in the reflective cup and mounted on the bottom thereof, the LED chip being configured for emitting first light of a first wavelength; a plurality of electrodes having first ends electrically connected to the LED chip and opposite second ends exposed at an outer surface of the reflective cup; a first light scattering layer comprising a first light pervious matrix and a plurality of light scattering particles dispersed therein, the first light scattering layer formed in the reflective cup on the bottom thereof and covering the LED chip, the first light scattering layer having a concave surface at an opposite side thereof to the LED chip, the first light scattering layer being configured for scattering the first light; and a phosphor layer comprising a second light pervious matrix and phosphor particles dispersed therein, the phosphor layer formed on the concave surface of the light scattering layer, the phosphor layer being configured for converting part of the first light into second light of a second wavelength.
