1. An instrument for curing light-curable compounds which are curable in the mouth of a patient, the instrument comprising:

  • a housing;

    a plurality of solid state, light-emitting elements, the elements comprising semiconductor junctions and being mounted on a substrate supported by the housing to form a collective array on said substrate, the array of elements operable for collectively emitting light having wavelengths within a narrow band of wavelengths;

    a generally clear layer simultaneously covering all of the plurality of light-emitting elements for protecting the array of semiconductor junctions;

    an optically reflective element coupled to surround the plurality of light-emitting elements to capture the collective light from an array of light-emitting elements and direct it forwardly away from the collective array an ultimately to a compound for curing.
