Patent ID: 7218041

Claim:
A light emitting device having an optical axis, comprising: a base member formed from a plurality of electric conductive members alternating with insulating members, the members being arranged in a direction perpendicular to the optical axis of the light emitting device, each of the insulating members being disposed to secure and isolate conductive members, the base member presenting first and opposite faces which are composed of alternating conductive and insulating members; a circuit substrate having an opening and which is secured to the first face of the base member, the opening being provided for exposing a part of an upper surface of one of the conductive members; a light emitting diode mounted on the exposed portion of the upper surface of the conductive member; an electrically connecting means to connect the light emitting diode with at least two of the conductive members for applying current to the light emitting diode; a sealing member covering the light emitting diode and the electrically connecting means for protection; and a projection outwardly extended for heat radiation from a side of the conductive member different from the side on which the light emitting diode is mounted.
