Abstract
There is provided a light emitting device highly resistant to the environment, and having good heat resistance, light resistance and gas barrier property, and a method for producing same. With the light emitting device, a substrate 2 and interconnect patterns 5A, 5B formed on the surface thereof are covered with an acrylic resin primer 10 having better gas barrier property than a silicone resin sealing resin part 3. Light resistance is ensured by the silicone resin sealing resin portion 3 and the gas barrier property can be ensured by the acrylic resin primer 10.
Claims9
A light emitting device comprising:
- a substrate;
- a metal portion formed on the substrate;
- an insulating layer which covers at least part of the metal portion;
- an LED chip mounted on the insulating layer;
- and
- a sealing resin portion which covers at least part of the insulating layer to seal the LED chip,
- wherein the insulating layer is made from a material which is higher in gas barrier property than the sealing resin portion, and
- wherein the insulating layer covers a top surface and outer side surfaces in a lateral direction of the metal portion.
