ABSTRACT:
A dental curing light including an elongate wand having a proximal end and a distal end, a plurality of LEDs disposed at or near a distal end of the elongate wand and a printed circuit board for mounting the plurality of LEDs. The LEDs include a main through mount LED and a plurality of surface mount LEDs positioned around the main through mount LED. The main LED is through mounted relative to the printed circuit board such that the power connections of the main through mount LED are made through a hole or holes in the printed circuit board. The power connections of the main through mount LED are made on an opposite surface of the printed circuit board relative to the “top” surface to which the surface mount LEDs are mounted.
