Abstract

The optical fiber indicator light includes a lighting device, an optical fiber and an optical guiding structure. The optical fiber has a first optical fiber point a second optical fiber point. The first optical fiber point is abutted on the lighting device and the second optical fiber point is opposed against the first optical fiber point. The optical guiding structure has a lens, a passage, and an air chamber connected with the passage. The air chamber is located behind the lens. A portion of the optical fiber is contained in the passage, and the second optical fiber point is placed in the air chamber. Light emitted from the optical fiber may be diffused by the air chamber to enlarge visible area of the optical fiber.

Claims
