A hand held dental instrument for curing light-curable compounds including a housing with a handle portion and a barrel portion configured for being manipulated for positioning a tip end of the barrel portion proximate to a curing site. A plurality of solid state, light-emitting elements are mounted in a collective array to collectively form a beam of light. The array of elements is operable for collectively emitting a beam of light having wavelengths within a band of wavelengths and at a power to cure a dental compound. The array of elements is positioned proximate to the tip end of the barrel portion and the emitted light beam from the array illuminating a curing site. A radiation focusing device is positioned proximate the array of elements at the tip end of the barrel portion to focus the beam of light before it illuminates the curing site.
1. A hand held dental instrument for curing light-curable compounds curable in the mouth of a patient comprising: a housing having a handle portion for being held by a user and a barrel portion, the barrel portion configured for being manipulated for positioning a tip end of the barrel portion proxi
1. A hand held dental instrument for curing light-curable compounds curable in the mouth of a patient comprising: a housing having a handle portion for being held by a user and a barrel portion, the barrel portion configured for being manipulated for positioning a tip end of the barrel portion proximate to a curing site for curing a light curable compound;a plurality of solid state, light-emitting elements mounted in a collective array on a substrate to collectively form a beam of light, each element including at least one semiconductor junction, the array of elements operable for collectively emitting a beam of light having wavelengths within a band of wavelengths and at a power to cure a dental compound;the array of elements being positioned proximate to the tip end of the barrel portion;a radiation focusing device positioned proximate the array of elements at the tip end of the barrel portion to focus the beam of light, the radiation focusing device including a lens with a continuous material layer formed on the substrate and over the semiconductor junctions of the array of elements to encapsulate the semiconductor junctions, such that the beam of light that comes from the lens directly illuminates the curing site for a more efficient transfer of the light to the curing site. 2. The hand held dental instrument of claim 1 wherein said band of wavelengths includes a blue light wavelength. 3. The hand held dental instrument of claim 2 wherein the band of wavelengths includes a wavelength of approximately 470 nanometers. 4. The hand held dental instrument of claim 1 further comprising a cooling element positioned in the barrel portion proximate the array of elements and configured for cooling the array of elements. 5. The hand held dental instrument of claim 4 wherein the cooling element includes a fan unit. 6. The hand held dental instrument of claim 4 wherein the cooling element includes a heat sink device. 7. The hand held dental instrument of claim 1 wherein the lens is a converging optical lens. 8. The hand held dental instrument of claim 1 wherein the lens is a microlens. 9. The hand held dental instrument of claim 8 wherein the microlens includes a curved microlens over at least one of the light-emitting elements. 10. The hand held dental instrument of claim 8 wherein the microlens includes a plurality of curved microlenses over respective light-emitting elements. 11. The hand held dental instrument of claim 1 wherein the continuous material layer encapsulates an area of the substrate around the array of elements. 12. The hand held dental instrument of claim 1 wherein at least some of the solid state, light-emitting elements are made of individual unpackaged semiconductor junctions. 13. The hand held dental instrument of claim 1 wherein the solid state, light-emitting elements are mounted on a generally circular substrate to form a beam. 14. The hand held dental instrument of claim 1 wherein at least some of the solid state, light-emitting elements are generally rectangular in shape. 15. The hand held dental instrument of claim 14 wherein at least some of the solid state, light-emitting elements are mounted side-by-side to form the collective array. 16. The hand held dental instrument of claim 1 wherein the substrate includes metal tracks formed thereon and the light-emitting elements are soldered to the metal tracks. 17. The hand held dental instrument of claim 1 wherein the substrate includes conductive pads on a surface of the substrate, the light-emitting elements being electrically connected to the conductive pads. 18. The hand held dental instrument of claim 17 wherein the light-emitting elements are electrically connected to the conductive pads by wire bonding.
