(Also, the additional energy/heat will help drying, so you pay for the hardware but the energy consumption for the light is totally free.)

LED packages are designed to radiate the heat in the opposite direction of the light, and they would need to be sealed behind some barrier away from the damp clothes anyway.

Just make the fresh cold air from outside pass through the heat sink and then go to the red hot resistance and then to the cloth.
