Light-guide coupler for modulating angular and spatial distributions of light source

摘要

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.

1. A light-guide coupler for modulating angular and spatial distributions of a light source, comprising:
a transmission body, one end of the transmission body defining a first opening, the other end of the transmission body defining a second opening, the width of the transmission body increasing in a direction from the first opening to the second opening and forming a curved portion in at least one side plane of the transmission body; a microstructure portion, configured on at least one plane of the transmission body, and comprising a plurality of microstructure devices; and an inner reflecting surface, formed in the transmission body and matched to the microstructure portion and the curved portion, the inner reflecting surface forming a light-transmission path between the first opening and the second opening, wherein the first opening defined as input and the second opening defined as output, or the first opening defines as output and the second opening defined as input, wherein the width of the transmission body increases in a horizontal plane, and the width of the transmission body neighboring the second opening is greater than the thickness of the transmission body, and wherein the microstructure devices are parallel to each other and linearly configured in a direction from the second opening to the first opening.
