Patent ID: 8337200

Claim:
A hand-held apparatus for curing resins, comprising: a housing having an opening; a heat-dissipating unit including a heat sink disposed inside the housing; a light-emitting unit disposed inside the housing to contact the heat sink, wherein the light-emitting unit has a substrate body, at least one first light-emitting element disposed on the substrate body and electrically connected to the substrate body, at least one second light-emitting element disposed on the substrate body and electrically connected to the substrate body, at least one light-diffusing sheet disposed on the at least one second light-emitting element, and a light-reflecting element disposed around the at least one first light-emitting element, the at least one second light-emitting element and the at least one light-diffusion sheet, wherein white light beams generated by the at least one second light-emitting element pass through the at least one light-diffusing sheet to form uniforming white light beams; a power supply unit electrically connected to the at least one first light-emitting element and the at least one second light-emitting element; and a light transmission unit connected to the opening of the housing and separated from the light-emitting unit.
