Patent ID: 7056116

Claim:
A dental curing light comprising: an elongated housing having a proximal end and a distal end; at least one light source disposed at the distal end of the housing, the light source and distal end being configured so as to be easily inserted into a patient's mouth when using the curing light to cure a dental composition; an elongated heat sink, disposed within said housing, said elongated heat sink comprising a first portion adjacent to said light source and a second portion separated from the light source, and wherein the elongated heat sink is further comprised of: a first layer comprising a first material having a first specific heat and a first thermal conductivity; a second layer comprising a second material different from said first material, said second material having a second specific heat and a second thermal conductivity; wherein the first layer surrounds the second layer so that the second layer forms a core within the first layer of the elongated heat sink, with the first layer contacting the light source; and wherein said first thermal conductivity is greater than said second thermal conductivity, and said second specific heat is greater than said first specific heat.
