Publication number: 20220202547Abstract: A dental curing light includes a thermally conductive device body that efficiently conducts heat away from a light emitting diode (LED) assembly. The thermally conductive device body extends between a proximal end and a light emitting distal end to which the LED assembly is thermally coupled. The thermally conductive device body includes a handle portion extending to the proximal end and that is sized and configured for a dental practitioner to hold and manipulate with the hand. The thermally conductive device body acts as a heat sink to efficiently conduct heat away from the LED assembly during use. An electronics assembly and a rechargeable battery are disposed within a cavity of the thermally conductive device body. A sleeve or collar can be attached to the proximal end of the thermally conductive device body.Type: ApplicationFiled: March 14, 2022Publication date: June 30, 2022Inventors: Dee Jessop, Jared Wayne Sheetz, Neil Thomas Jessop

Patent number: 11273021Abstract: A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode (LED) portion of the curing light. The device body is one-piece body formed from a continuous seamless piece of thermally conductive material extending between a proximal end and a distal end. The one-piece body includes a gripping handle portion extending to the proximal end and a light-emitting head portion extending to the distal end. The one-piece thermally conductive body acts as a heat sink to efficiently conduct heat away from the LED dies during use. The one-piece body eliminates problems of multi-segmented curing lights that include one or more joints between adjacent segments. Eliminating joints increases thermal conductivity of the body, eliminates crevices where microbes can grow, and eliminates the risk of accidental separation if the curing light is dropped.Type: GrantFiled: April 29, 2020Date of Patent: March 15, 2022Assignee: ULTRADENT PRODUCTS, INC.Inventors: Dee Jessop, Jared Wayne Sheetz, Neil Thomas Jessop

Patent number: 11007043Abstract: A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode portion of the curing light. The device body includes a proximal gripping end and a distal head end. The device body is formed from a thermally conductive body material. Excellent heat conduction away from the LED dies is achieved using a thermally conductive layer disposed over the device body. The thermally conductive layer serves as a conduit to quickly conduct heat away from the LED dies for dissipation within the material of the device body. In this manner, the material of the device body serves as a highly efficient heat dissipater. The surface area coupling the thermally conductive layer to the device body is sufficiently large that a majority (e g, substantially all) of heat being conducted by the thermally conductive layer is transferred to the device body during operation of the device.Type: GrantFiled: January 18, 2019Date of Patent: May 18, 2021Assignee: Ultradent Products, Inc.Inventors: Dee Jessop, Jared Sheetz, Neil T.
