LIGHT EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light emitting device in which reliability and directivity are enhanced.

SOLUTION: The light emitting device comprises: a tubular frame 40 surrounding an LED chip 10 on the mounting surface side of a mounting substrate 20; an elastic sealing portion 50 formed by filling the inside of the frame 40 with silicon resin and sealing the LED chip 10 and bonding wires 14 and 14 connected with the LED chip 10; a lens 60 arranged on the sealing portion 50; and a domelike color transformation member 70 formed of a yellow phosphor excited by blue light radiated from the LED chip 10 and of a translucent material and arranged on the mounting surface side of the mounting substrate 20 to surround the lens 60 and the frame 40 thus forming an air layer 80 on the inside. The lens 60 is constituted of a biconvex lens.
