Abstract
A light curing device includes a light source disposed at a distal end and a focusing means configured to focus light emitted from the light source. The light source is an LED light source and may include any quantity of LEDs. The focusing means includes lenses configured to collimate the light emitted from the light source. Hemispheric lenses are concentrically aligned with the individual LEDs in one embodiment. Aspheric lenses are concentrically misaligned with the individual LEDs in another embodiment. The LEDs can also be offset by particular angles and distances to channel the light into a desired path of illumination with a desired footprint.
Claims20
A dental device configured for curing light-curable compounds, comprising:
- a body extending between a proximal end and a distal end;
- a plurality of LED light sources disposed at the distal end of the body;
- and
- a focusing means for collimating light emitted from a plurality of LED light sources.
A dental device configured for curing light-curable compounds, comprising:
- a body extending between a proximal end and a distal end;
- two LEDs disposed at the distal end of the body;
- and
- two lenses, each of said lenses disposed adjacent to a different one of said LEDs and configured to focus light emitted from said LEDs into a desired footprint.
A dental device configured for curing light-curable compounds, comprising:
- a body extending between a proximal end and a distal end;
- two LEDs disposed at the distal end of the body, wherein the two LEDs are offset by a predetermined distance and a predetermined angle such that the light emitted from the two LEDs is channeled into a path of illumination having a desired elliptical footprint.
