Abstract
A light guide unit provided in this disclosure is used for performing a reversible optical conversion process on a light source. In an embodiment, the light guide unit is used for converting a planar light source into at least a linear light source, and then further to be converted into one point light source, while allowing beams emitted from the point light source to be guided and shot to a specific position by the use of a light-guiding element. Moreover, in another embodiment, the light guide unit is used for converting at least one point light source into at least a linear light source, and then further to be converted into a planar light source for emitting light. The light guide unit can be adapted for various applications, such as optical devices for illumination, entertainment, decoration or ornaments.
