A hand-held apparatus for curing resins includes a housing, a heat sink, a light-emitting unit, a power supply unit and a light transmission unit. The heat sink is installed in the housing. The light-emitting unit is installed on the heat sink. The light-emitting unit has at least one first light-emitting element for generating first wavelength light to cure the resins, at least one second light-emitting element for generating second wavelength light to generate white light, and at least one light-reflecting element surrounding the at least one first light-emitting element and the at least one second light-emitting element for reflecting the first wavelength light and the second wavelength light. The power supply unit provides power for the light-emitting unit. The light transmission unit is coupled to the housing for transmitting the first wavelength light and the second wavelength light to the resins.
