Abstract
A light-emitting structure for generating an annular illumination effect includes a light-guiding module, a cover module, and a first light-emitting module. The light-guiding module has a hollow light-guiding body and a reflecting layer formed on an inner surface of the hollow light-guiding body. The cover module has a first cover body disposed on one end side of the hollow light-guiding body and a second cover body disposed on the other opposite end side of the hollow light-guiding body. The first light-emitting module has a plurality of first light-emitting elements disposed between the hollow light-guiding body and the first cover body. Therefore, first light beams generated by the first light-emitting elements are projected onto the hollow light-guiding body, and the first light beams are guided by the hollow light-guiding body and are reflected by the reflecting layer in order to make the hollow light-guiding body generate the annular illumination effect.
