Abstract

The invention provides a light source device and a light source system. The light source device includes a lens and a light source. The lens has a light-emitting top surface, and the light source is used 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 parallelto the light-emitting top surface. The 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 conventional light distributions are subsequently replaced.

Description

technical field [0001] The present invention relates to a light source device and a light source system, specifically, the present invention relates to a light source device and a light source system capable of producing high-contrast light shape distribution. Background technique [0002] In various technical fields, especially in the fields of display technology and illumination equipment, light source design has always been an important aspect of light sources. Existing light sources usually use bulbs or incandescent tubes as light sources. With the maturity of light-emitting diode (LED) technology and the advantages of small size, energy saving and environmental protection, light-emitting diodes have gradually become the mainstream of the market. [0003] However, when multiple light sources are configured together, the light sources of a display are usually designed to direct light at a wide angle so that the concentrated light output is relatively uniform. Although s...
