Abstract
Disclosed is an LED lighting system comprising a housing equipped with a transparent substrate as an illuminating side, an LED light source located in the housing, and a haze-changeable film attached to the transparent substrate, wherein the transparency of the haze-changeable film changes depending on the application of electric power and the haze-changeable film has a haze on light varying with the intensity of an applied voltage/current. The LED lighting system may be useful for interior emotional lighting because a direct/indirect lighting and a mixed lighting thereof can be provided with a single system and various correlated color temperatures can be produced with a single LED light source.
