Abstract
The portable photocuring device has a light emission diodes matrix which can be energized with battery power to provide optical power for photocuring curing purposes. The diodes can be easily controlled and adjusted to emit light of selected colors and intensity with complex instrumentation.
Claims4
A hand-held portable photocuring device comprising,
- a portable housing having a front end and rear end,
- a light emitting semiconducting means having a matrix of a plurality of light emitting diode means mounted at said front end, said light emitting diode means being operative to emit in combination a light energy suitable for photocuring,
- a power means coupled to said semiconducting means and operative to provide the electrical power for energizing said plurality of light emitting diode means to emit in combination said light energy,
- control means connected to said semiconducting means and said power means, and operative to vary the level of said light energy,
- a mounting means provided at said front end of said housing,
- a tubular light guide member mounted to said mounting means, said light guide member being operative to direct said light energy generated from said light emitting diode means to a photocuring location disposed adjacent to a distal free end of said light guide member,
- a transparent cap member mounted at said front end and covering over said light emitting diode means,
- a heat sink means disposed juxtaposed to said semiconducting means and being operative to dissipate heat generated in said semiconducting means.
