Abstract:
An LED light-emission device includes a substrate, an LED chip, a phosphor-containing resin containing a phosphor and covering the LED chip, and a diffusing agent-containing resin containing a diffusing agent that diffuses light emitted from the phosphor-containing resin and sealing the phosphor-containing resin. The LED chip, the phosphor-containing resin, and the diffusing agent-containing resin are placed on a same flat face of the substrate.
