ABSTRACT:
A lighting device for illuminating ice has a sheet of light-transmitting film located below an ice layer and coupled to a light source. The index of refraction of the light-transmitting film is greater than that of the adjoining ice or air so that the light within the film experiences substantial internal reflection. Light is emitted from the film (and the ice surface) at emission regions that disrupt internal reflection.
