1. An infrared (IR) light device comprising:
- a main casing filled with a gas to prevent condensation from forming on an interior surface of a light filter mounted inside the main casing;
a plurality of IR light emitting diodes (LEDs) mounted in the main casing; and
a heat transfer structure for transferring heat from the LEDs to the main casing, wherein the heat transfer structure comprises;
copper fillings positioned in bores in a circuit card to which the LEDs are mounted, the copper fillings being coupled to the LEDs;
a metal plate positioned to contact the copper fillings; and
thermal transfer elements contacting the metal plate and the main casing.
