Abstract
There is provided a lighting device which has at least one solid state light emitter and a substantially transparent heat sink. The heat sink and the solid state light emitter are positioned and oriented relative to one another such that if the solid state light emitter is illuminated, light emitted by the solid state light emitter which exits the lighting device passes through at least a portion of the heat sink. Also, there is provided a lighting device which has at least one solid state light emitter and means for extracting heat from the solid state light emitter.
Claims60
A lighting device, comprising:
- at least a first solid state light emitter;
- and
- a substantially transparent heat sink,
- said heat sink and said first solid state light emitter positioned and oriented relative to one another such that if said solid state light emitter is illuminated, substantially all the light that is emitted by said first solid state light emitter and that exits the lighting device passes through said substantially transparent heat sink.
A lighting device, comprising:
- at least a first solid state light emitter;
- a substantially transparent heat sink;
- and
- a heat spreader;
- said heat sink and said first solid state light emitter positioned and oriented relative to one another such that if said first solid state light emitter is illuminated, light emitted by said first solid state light emitter which exits the lighting device passes through at least a portion of said heat sink;
- said substantially transparent heat sink on a first side of said solid state light emitter and said heat spreader on a second side of said solid state light emitter.
A lighting device, comprising:
- at least one solid state light emitter;
- and
- means for extracting heat from said solid state light emitter.
A lighting device, comprising:
- at least a first solid state light emitter;
- at least one substantially transparent heat sink;
- at least one reflective element;
- and
- at least a first electrical conductor, at least a portion of which is electrically conductive;
- the at least one reflective element and the substantially transparent heat sink in combination substantially surrounding the solid state light emitter, except where the at least one electrical conductor extends through the substantially transparent heat sink.
A lighting device, comprising:
- at least a first solid state light emitter;
- at least one substantially transparent heat sink;
- at least one encapsulant;
- at least one reflective element;
- and
- at least a first electrical conductor, at least a portion of which is electrically conductive;
- the at least one reflective element, the at least one substantially transparent heat sink and the at least one encapsulant in combination substantially surrounding the solid state light emitter, except where the at least one electrical conductor extends through the substantially transparent heat sink.
A lighting device, comprising:
- at least a first solid state light emitter;
- a substantially transparent heat sink, at least some of the light emitted by the first solid state light emitter passing through the heat sink;
- and
- at least one electrical conductor electrically connected to the first solid state light emitter,
- at least a portion of the at least one electrical conductor is electrically conductive;
- the at least one electrical conductor extends through said substantially transparent heat sink;
- and
- said solid state light emitter is substantially surrounded by said substantially transparent heat sink, except where the at least one electrical conductor extends through said substantially transparent heat sink.
