Light-emitting device
Abstract:
To provide a light emitting device easy to produce and extracting light to its outside with high efficiency, the light-emitting device 70 of the present invention includes an insulating base 10; a light-emitting element 1 mounted on a side of the base 10; and a protection element 2 mounted on the side and protecting the light-emitting element 1. The element 2 is covered with a light-reflecting filler-containing resin 5, which is prepared by causing a flexible silicone resin to contain, before being cured, light-reflecting or light-scattering fillers 5a having a particle diameter larger than the wavelength of light emitted by the element 1. This causes light emitted from the element 1 to be reflected by the resin 5, instead of being absorbed by the element 2, so that such light is released to the outside of the light-emitting device 70. This allows the device 70 to extract light to the outside with high efficiency, and also allows for easy formation of the resin 5 having a desired pattern and position.
