ABSTRACT:
A light emitting device, in which an encapsulation resin is disposed at a space confined between an optical member and a mounting substrate. This encapsulation resin is possibly made free from a void-generation therein. In this light emitting device, the optical member can be precisely positioned. An electrode disposed outside a color conversion member is possibly free from an improper solder connection. A ring gate is formed on the top surface of the mounting substrate outside of the optical member, and acts to position the color conversion member. The ring gate acts to prevent an overflowing liquid encapsulation resin from flowing to the electrode provided. The ring gate is provided with a plurality of centering projections which are spaced circumferentially along its inner circumference to position the color conversion member.
