  • Patent number: 10145535
    Abstract: A light source device includes a lens and a light source. The lens has a light-emitting top surface, and the light source is for generating light and is disposed below the lens. Light from the light source is refracted by the lens to cause a light distribution to be produced when projected onto a planar surface parallel to the light-emitting top surface. A light source system includes a plurality of the light source devices disposed in a matrix arrangement. Through the light distribution produced by the lens of the light source devices and the light source system, high contrast effects may be generated and subsequently replace conventional light distributions.
