Abstract: NOVELTY - The package has a LED chip (120) mounted on package body (100) and emitting excited light. A phosphor layer has phosphor (140) absorbing excited light and emitting a wavelength conversion light obtained by converting a wavelength of the excited light. The phosphor layer has a phosphor resin (150) mixed with the phosphor. A reflector layer includes a reflector (170) formed between the LED chip and the phosphor layer, transmitting the excited light to the phosphor layer, and reflecting the wavelength conversion light from the phosphor layer. A reflector resin (180) is mixed with the reflector.

USE - LED chip package.

ADVANTAGE - Increases light emitting efficiency of the LED chip package.

DESCRIPTION OF DRAWING(S) - The drawing shows the cross-section diagram of the LED chip package.
