The utility model relates to a light signal device for resisting the mirage effect, which comprises a parallel light tube with a reflector (2), a light source (1) positioned on the parallel light tube focus (F) and a light absorber (3). The mirror (2) and (3) absorber set such that any one with each other, to the reflective mirror (2) of the focused beam (5) converging beam in the opposite direction (4) will be launched into the absorber (3). A mirror (2) can be made of a mirror or a reflection refraction ring (23) for a full internal reflection. The structure can eliminate the interference of the external light and improve the contrast of the optical signal.
