    • The present invention relates to a heat sink material that can more efficiently remove or divert heat from a light source or sources with a given weight of heat sink material when compare to a heat sink made of a solid block of thermally conductive material such as metal. It further relates to a heat sink that can more efficiently remove or divert heat from a curing light device when a reduced weight of heat sink material is used. The inventive heat sink has at least one suitable phase change material including organic materials, inorganic materials and combinations thereof. These materials can undergo substantially reversible phase changes, and can typically go through a large, if not an infinite number of cycles without losing their effectiveness.
    • 本发明涉及一种散热材料,当与由诸如金属的导热材料的固体块制成的散热器相比时,散热材料可以更有效地从具有给定重量的散热材料的光源或源移除或转移热量。 它还涉及一种散热器,当使用减重的重量的散热材料时,可以更有效地从固化灯装置中去除或转移热量。 本发明的散热器具有至少一种合适的相变材料,包括有机材料,无机材料及其组合。 这些材料可能经历基本上可逆的相变,并且通常可以经历大的(如果不是无限数量的循环)而不失去其有效性。
