Abstract
The present invention relates to an optical structure, which comprises a lens module, a reflective housing, and a light-emitting device. The lens module includes a lens body, which includes a first curved surface and a second curved surface connected symmetrically. The first curved surface extends from the top of the lens body to the front and left sides and reaches the bottom part; the second curved surface extends from the top of the lens body to the front and right sides and reaches the bottom part. The reflective housing includes a housing, which includes a reflective concave surface facing the lens module. In addition, one end of the housing is higher than the lens module. The light-emitting device is disposed between the lens module and the reflective housing and inside the lens module. By using the design of optical structure, light-emitting devices are enabled to project light with high uniformity.
