Abstract
A curing light system useful for curing light activated composite materials is disclosed. Various configurations of light emitting semiconductor chips and heat sinks are disclosed, as well as various structures and methods for driving, controlling and using them.
Claims17
A curing light comprising:
- a housing for housing components of a curing light,
- a pistol grip on said housing for grasping by a human hand,
- a trigger on said housing proximal to said pistol grip for actuation by a human finger to cause light to be emitted by the curing light,
- air space within said housing,
- at least one air vent located on said housing,
- a secondary heat sink located within said housing, said secondary heat sink having a proximal and a distal side,
- a thermoelectric cooler to assist in heat dissipation located on said secondary heat sink proximal side,
- a fan located within said housing, said fan being capable of causing air to move past said thermoelectric cooler in order to improve heat dissipation,
- a plurality of light emitting semiconductor modules located on said heat sink distal side, each of said semiconductor modules including
- a primary heat sink,
- a semiconductor chip which emits light of a wavelength useful for curing light curable composite materials, said chip being affixed to said primary heat sink,
- a cover serving to protect said chip,
- a first light reflective device which collects light emitted by said semiconductor modules and reflects it as a light beam,
- a focusing lens which serves to focus said light beam from said first light reflective device into a concentrated light beam, and
- a second light reflective device which reflects said concentrated light beam in a direction where it may be used to cure composite materials.
