Dental light device

摘要

A light device includes a body and a tip structure configured to be removably coupled with the housing. The tip includes a light engine that is operable for emitting light positioned at a distal end of the tip. A power supply circuit is positioned in the housing and coupled to the light engine. The power supply circuit is rechargeable and includes at least one ultracapacitor element. A non-imaging element is coupled with the light engine at the distal end.

1. A curing light device comprising:
a body including a housing and a socket at an end thereof; a tip having a proximal end and a distal end, the proximal end configured for plugging into the body socket to removably secure the tip with the body; the tip including a plurality of body elements formed of an electrically and thermally conductive material, the body elements electrically isolated from each other to form separate electrical conductors in the tip and collectively operating to provide thermal conduction of heat in the tip; a light engine including at least one light emitting element operable for emitting light, the light engine positioned on the distal end of the tip and electrically coupled with the tip body elements to receive power and thermally coupled with the tip body elements for removing heat; a non-imaging element coupled with the light engine at the distal end of the tip for capturing and collimating the emitted light; a power supply positioned in the body housing and electrically coupled with electrical contacts in the socket, the tip body elements engaging the socket electrical contacts to conduct electrical enerqy to power the light engine, the power supply being rechargeable and including at least one ultracapacitor element.
