1. A curing light comprising:

  • a wand adapted to be grasped by a human hand for use in positioning and manipulating the curing light, a light module attached to said wand, said light module including an elongate heat sink with a proximal end and a distal end, said proximal end being proximate said wand, said elongate heat sink having a longitudinal axis, a mounting platform located at said elongate heat sink distal end, said mounting platform being adapted to have a LED chip module, and an LED chip module mounted on said mounting platform, said LED chip module including a primary heat sink, said primary heat sink having a smaller mass than said elongate heat sink a well on said primary heat sink for mounting an LED chip, an LED chip mounted in said well, a cover that provides protective covering for said LED chip and which permits light emitted by said LED chip to pass through it to provide usable light exiting from said light module;

    wherein said LED chip module is mounted on said mounting platform so at least some that light emitted by said LED chip module travels away from said LED chip module in a linear direction that represents an angle with respect to said elongate heat sink longitudinal axis in the range of 30 to 150 degrees.
