Led light emitting device

An LED light emitting device comprising:

• a mount substrate having a base, a reflection layer containing silver and laminated on the base, and a multilayer reflection film laminated on the reflection layer;
• an LED die emitting blue light and mounted in a light emitting area on the mount substrate;
• a sealing resin including fluorescent substance particles and sealing the LED die and the surface of the mount substrate within the light emitting area;
• a DBR layer arranged on the undersurface of the LED die and shielding at least part of blue light emitted from the LED die;
• and
• a transparent material arranged between the multilayer reflection film and the sealing resin so as to cover at least part of the surface and the lateral surface of the LED die, wherein
• the DBR layer is a layer in which a plurality of sets of dielectrics including a high-refractive index layer and a low-reflective index layer is laminated, and
• the fluorescent substance particles precipitate within the sealing resin and form a fluorescent substance layer covering part of the lateral surface of the LED die and part of the surface of the multilayer reflection film within the light emitting area.
