Abstract
An artificial skylight generally includes at least one light source, at least one first collimator, a prism sheet, and at least one transmissive material. The at least one first collimator is configured to collimate light from the at least one light source. The prism sheet is disposed adjacent to the at least one first collimator and is configured to reflect and refract collimated light received from the at least one first collimator. The at least one transmissive material is disposed adjacent to the prism sheet and is configured to radiate light diffusely.
