Abstract
A light-guide coupler for modulating angular and spatial distributions of a light source is provided. The light-guide coupler includes a transmission body and a microstructure portion. One end of the transmission body defines a first opening. The other end of the transmission body defines a second opening. The width of the transmission body increases in a direction from the first opening to the second opening and forms a curved portion in at least one side plane of the transmission body. The microstructure portion is configured on one plane of the transmission body. An inner reflecting surface is formed in the transmission body and matched to the microstructure portion and curved portion. The inner reflecting surface forms a light transmission path between the first opening and the second opening.
