Abstract
A lighting device comprising a solid state light emitter and a fan, the fan blowing fluid toward the emitter. A lighting device comprising a solid state light emitter and a baffle, the solid state light emitter being movable. A lighting device comprising a solid state light emitter, a substrate and a diaphragm, the diaphragm defining a chamber having a valve and being movable. A lighting device comprising a housing and a solid state light emitter within the housing, the solid state light emitter being movable. Also, methods of cooling a lighting device.
Claims33
A lighting device comprising:
- at least one solid state light emitter;
- and
- at least one fan, the solid state light emitter and the fan being positioned relative to one another and the fan being oriented such that when power is supplied to the fan, the fan blows fluid toward the solid state light emitter.
A lighting device comprising:
- at least one solid state light emitter, the solid state light emitter being movable between at least a first position and a second position;
- and
- at least one baffle.
A lighting device comprising:
- at least one solid state light emitter;
- a substrate;
- and
- a diaphragm, the diaphragm defining at least one chamber having at least one valve,
- the solid state light emitter being mounted on the substrate,
- the chamber being positioned adjacent to the substrate,
- the diaphragm being movable between at least a first diaphragm position and a second diaphragm position.
A method of cooling a lighting device comprising supplying power to at least one fan and blowing fluid toward at least one solid state light emitter.
A method of cooling a lighting device comprising:
- moving a solid state light emitter between a first position and a second position relative to a first baffle,
- creating a fluid flow due to the movement, and
- flowing the fluid adjacent to the solid state light emitter.
A method of cooling a lighting device comprising:
- moving a diaphragm from a first diaphragm position to a second diaphragm position;
- and
- cooling a lighting device.
A lighting device comprising:
- a housing;
- and
- at least one solid state light emitter,
- the solid state light emitter being movable relative the housing between at least a first position and a second position.
A method of cooling a lighting device comprising:
- moving a solid state light emitter relative to a housing between a first position and a second position, the solid state light emitter being mounted within the housing;
- and
- cooling the solid state light emitter.
