Abstract
A light emission device includes a light emitter, a light reflection member, and a resin sealing the light emitter by covering the light reflection member and the light emitter, in which light deviated from a predetermined front region in the light emitted from the light emitter is totally reflected by a boundary surface of the resin to be forwardly emitted by the light reflection member, and the emitter is thermally contacted with the reflection member to dissipate the heat generated from the light emitter.
Claims9
A light emission device comprising
- a light emitter,
- a light reflection member, and
- a resin sealing said light emitter by covering said light reflection member and said light emitter, in which light deviated from a predetermined front region in the light emitted from said light emitter is totally reflected by a boundary surface of said resin to be forwardly emitted by said light reflection member, and said emitter is thermally contacted with said reflection member to dissipate the heat generated from said light emitter.
A light emission device comprising
- a light emitter,
- a light reflection member, and
- a resin sealing said light emitter by covering said light reflection member and said light emitter, in which light deviated from a predetermined front region in the light emitted from said light emitter is totally reflected by a boundary surface of said resin to be forwardly emitted by said light reflection member, said light emitter is mounted on a vertical plane body having a good thermal conductivity, and said vertical plane body is thermally connected with said light reflection member to dissipate heat of said light emitter through said vertical plane body and said light reflection member.
A light emission device comprising
- a light emitter,
- a light reflection member, and
- a resin sealing said light emitter by covering said light reflection member and said light emitter, in which light deviated from a predetermined front region in the light emitted from said light emitter is totally reflected by a boundary surface of said resin to be forwardly emitted by said light reflection member, and said light reflection member is formed with a lead frame as a single unit to dissipate heat of said light emitter mounted on said lead frame through said light reflection member.
A light emission device comprising
- an optical member having a light reflection member and a resin covering said light reflection member, and
- a light emitter of a surface mount type mounted on a metal plate, in which said resin is so constructed to direct light deviating from a predetermined front region about the light emitted from said light emitter to be almost totally reflected at a boundary surface of said resin for forward emission by said light reflection member, and said light reflection member is thermally contacted with said metal plate to dissipate heat of said light emitter.
A light emission device comprising
- a plurality of light reflection portions formed on a metal member in an array fashion,
- a plurality of light emitters each mounted near center of each of said light reflection portions to be die-bonded,
- a wiring pattern disposed on a surface of said metal member through an insulation film to be connected with each of said light emitters, and
- resins covering said light emitters above said light reflection portions, in which each of said resins is formed to direct light deviating from a predetermined front region about the light emitted from each of said light emitters to be almost totally reflected at a boundary surface of said resin for forward emission by each of said light reflection portions, and heat generated from each of said light emitters is dissipated by said metal member.
