ABSTRACT:
A light-emitting device can include a blue LED chip that is covered in a sealing resin composed of a filling resin mixed with a wavelength conversion material, such as a yellow fluorescent material. Light from the blue LED chip is mixed with a light from the yellow fluorescent material to obtain white light emission having a mixed color. The sealing resin has a light emission surface, which can be symmetrical about the normal line passing through the center of the blue LED chip. An optical multi-layered film including layered high- and low-refractive index films can be provided on the light emission surface.
