Abstract
The light emitting device is provided with a substrate, semiconductor light emitting elements mounted on the substrate, a mold frame that surrounds the periphery of the light emitting elements on the substrate, and resin layers that fill the inside of the mold frame. The mold frame includes a first mold frame, and a second mold frame formed on top of the first mold frame. The resin layers include a first resin layer that embeds the light emitting elements in resin and is formed with a height approximately equal to the height of the top of the first mold frame, and a second resin layer on top of the first resin layer that is formed with a height approximately equal to the height of the top of the second mold frame. At least one of the resin layers (which are the first resin layer and the second resin layer) includes wavelength-shifting material to change the wavelength of light emitted from the semiconductor light emitting elements.
