Abstract
A heat sink for a dental light-curing device comprises three mounting surfaces that are each configured for mounting a light source, such as an LED or LED array, which is capable of generating light suitable for curing light-curable compounds. The mounting surfaces are configured with a geometric arrangement in which one of the mounting surfaces is placed nearer to the tip of the heat sink than either of the remaining two mounting surfaces, which are placed adjacent to the first mounting surface and are spaced an equal distance away from the tip of the heat sink. This arrangement generally minimizes the heat that is generated by the LEDs at the tip of the heat sink and expedites the diffusion of heat from the LEDs.
Claims20
A heat sink for a dental light-curing device comprising:
- a body extending between a proximal end and a distal end;
- and
- a face located near the distal end of the body that includes:
- a proximal half;
- a distal half;
- and
- a plurality of mounting surfaces configured for mounting light sources on the face, the mounting surface having a combined surface area, wherein a majority of the combined surface area of the mounting surfaces is located in the proximal half of the face.
A heat sink for a dental light-curing device comprising:
- a body extending between a proximal end and a distal end;
- and
- a face located near the distal end of the body and including:
- a proximal half;
- a distal half;
- and
- three mounting surfaces configured for mounting a single light source within the distal half and at least two light sources within the proximal half.
A dental light-curing device comprising:
- a heat sink including:
- a body extending between a proximal end and a distal end;
- and
- a face configured for mounting light sources, the face including a proximal portion and a distal portion having substantially equal lengths, wherein the proximal portion is configured to mount two light sources and wherein the distal face portion is configured to mount a single light source;
- a single light source mounted on the distal face portion;
- and
- two light sources mounted on the proximal face portion.
