A light emitting device comprising: light emitting diode chip; a mounting substrate mounting said LED chip; a dome-shaped optical member being secured to a top surface of said mounting substrate to cover said LED chip for directing a light emitted from said LED chip therethrough; a light-transmissive encapsulation resin which is filled in a space confined between said optical member and said mounting substrate for encapsulating said LED chip therewith; a dome-shaped color conversion member made of a transparent resin material and a phosphor which is excited by a light emitted from said LED chip to emit a light of a color different from a luminescent color of the LED chip, said color conversion member being disposed on the top surface of the mounting substrate to surround said optical member; a patterned conductor configured to have electrodes exposed outside of said color conversion member on the top surface of said mounting substrate for electrical connection with said LED chip; characterised by: a ring gate which protrudes from the top surface of said mounting substrate to separate said optical member from said electrodes for preventing said encapsulation resin from flowing to said electrode, said ring gate being engaged at its outer circumference with said color conversion member to position said color conversion member, said ring gate being provided with a plurality of centering projections which are spaced circumferentially along its inner circumference to come into contact with an outer periphery of said optical member. light emitting diode chip; a mounting substrate mounting said LED chip; a dome-shaped optical member being secured to a top surface of said mounting substrate to cover said LED chip for directing a light emitted from said LED chip therethrough; a light-transmissive encapsulation resin which is filled in a space confined between said optical member and said mounting substrate for encapsulating said LED chip therewith; a dome-shaped color conversion member made of a transparent resin material and a phosphor which is excited by a light emitted from said LED chip to emit a light of a color different from a luminescent color of the LED chip, said color conversion member being disposed on the top surface of the mounting substrate to surround said optical member; a patterned conductor configured to have electrodes exposed outside of said color conversion member on the top surface of said mounting substrate for electrical connection with said LED chip; characterised by: a ring gate which protrudes from the top surface of said mounting substrate to separate said optical member from said electrodes for preventing said encapsulation resin from flowing to said electrode, said ring gate being engaged at its outer circumference with said color conversion member to position said color conversion member, said ring gate being provided with a plurality of centering projections which are spaced circumferentially along its inner circumference to come into contact with an outer periphery of said optical member. a ring gate which protrudes from the top surface of said mounting substrate to separate said optical member from said electrodes for preventing said encapsulation resin from flowing to said electrode, said ring gate being engaged at its outer circumference with said color conversion member to position said color conversion member, said ring gate being provided with a plurality of centering projections which are spaced circumferentially along its inner circumference to come into contact with an outer periphery of said optical member.
