Radiation emitter device having an integral micro-groove lens

A radiation emitter assembly comprising:

• at least one discrete radiation emitter device comprising:
• at least two radiation emitters emitting radiation of different wavelengths;
• a leadframe including a heat extraction member in thermal contact with at least one of said radiation emitters, said leadframe further including first and second electrical leads electrically coupled to at least one of said radiation emitters;
• and
• an encapsulant configured to encapsulate said radiation emitters and a portion of said first and second electrical leads, said heat extraction member extending out from said encapsulant to provide a first thermal path from at least one of said radiation emitters, said first thermal path being separate from a second thermal path provided by said first and second electrical leads, said encapsulant further configured to have a surface defining a divergent optical lens;
• and
• a secondary reflective cup disposed proximate said divergent optical lens of said radiation emitter device;and
• wherein said first thermal path provided by said heat extraction member has a lower thermal resistance than said second thermal path provided by said electrical leads.

• at least one discrete radiation emitter device comprising:
• at least two radiation emitters emitting radiation of different wavelengths;
• a leadframe including a heat extraction member in thermal contact with at least one of said radiation emitters, said leadframe further including first and second electrical leads electrically coupled to at least one of said radiation emitters;
• and
• an encapsulant configured to encapsulate said radiation emitters and a portion of said first and second electrical leads, said heat extraction member extending out from said encapsulant to provide a first thermal path from at least one of said radiation emitters, said first thermal path being separate from a second thermal path provided by said first and second electrical leads, said encapsulant further configured to have a surface defining a divergent optical lens;
• and
• a secondary reflective cup disposed proximate said divergent optical lens of said radiation emitter device;and
• wherein said first thermal path provided by said heat extraction member has a lower thermal resistance than said second thermal path provided by said electrical leads.
