Abstract:
1. A light emitting apparatus having a light emitting device mounted on a substrate or a resin package where a substrate surface or the resin package is resin-encapsulated by an encapsulating resin section comprising an encapsulating resin added with a first phosphor in such a manner to cover the light emitting device and configured to control a color of light output by the light emitting apparatus, wherein a thickness of the encapsulating resin section is configured to balance with a white color of the light emitting apparatus when the light emitting device is not emitting light, the encapsulating resin section is a translucent mold section, which is divided, from the side closer to the light emitting device, into a layer substantially including the first phosphor, an intermediate layer including the first phosphor, an optical diffusion material and a second phosphor and a layer substantially including the optical diffusion material and the second phosphor that is substantially precipitated to a surface side of the encapsulating resin section, such that the layer substantially including the optical diffusion material and the second phosphor has a different color from that of the layer substantially including the first phosphor, and a portion of the encapsulating resin section containing the optical diffusion material and the second phosphor is configured to cause a surface of the encapsulating resin section to appear white when the light emitting device is not emitting light.
