  • Patent number: 7767475
    Abstract: Light emitting device 1 includes an LED chip 10, a mounting substrate 20 carrying the LED chip, a dome-shaped color conversion member 70, and encapsulation member 50. Color conversion member 70 is molded from a transparent resin material and a fluorescent material which is excited by a light emitted from the LED chip to emit a light of a color different from a luminescent color of the LED chip, and is bonded to the mounting substrate to surround LED chip 10. Encapsulation member 50 is made of an encapsulation resin material to encapsulate LED chip 10 and bonding wires 14 within a space confined between mounting board 20 and color conversion member 70. Encapsulation member 50 is of a convex-shape to have its light output surface 50b kept in an intimate contact with an internal surface of color conversion member 70.

  • Publication number: 20100163914
    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.
