Abstract:
A light emitting diode includes a reflective cup, an LED chip, and many electrodes, a first light scattering layer, and a phosphor layer. The reflective cup includes a bottom and a sidewall extending from the bottom. The LED chip is received in the reflective cup and mounted on the bottom thereof for emitting first light of a first wavelength. The electrodes each has a first end electrically connected to the LED chip and an opposite second end exposed at an outer surface of the reflective cup. The first light scattering layer formed in the reflective cup on the bottom thereof and covering the LED chip, which has a concave surface at an opposite side thereof to the LED chip. The phosphor layer formed on the concave surface of the light scattering layer for converting part of the first light into second light of a second wavelength.
