Abstract
A light device with integration sheet is disclosed, which comprises: a light source; and at least a sheet, each being disposed at the light emitting end of the light source and comprising a plurality of light diffusion zones; wherein each light diffusion zone has a plural arrays of microstructures arranged on the surface thereof, and each array of microstructures is capable of changing the diopter of the corresponding light diffusion zone. By controlling the distribution of the plural arrays of microstructures, the Gaussian distribution of the light source can be improved while collimating the scattered light beams to the intended illuminating area of the lighting device and diffusing the light beams emitting from the center of the light source to the same so that not only the luminous efficacy of the lighting device is enhanced, but also the uniformity of the illuminance of the lighting device is improved.
