Abstract
A light indicator includes a reflector element, a transparent element, and an emitting element. The transparent element includes a light incident surface and a light emitting surface. The emitting element is arranged symmetrically on two sides of the transparent element so that light beams emitted from the emitting element can enter into the transparent element though the light incident surface and the light emitting surface can emit uniform light beams. The reflector element surrounds the transparent element and the emitting element to ensure that part of light beams can enter into the transparent element through the light incident surface after being reflected one or more times. The light indicator of the invention has a uniform light distribution and a high utilization rate of light.
