A lateral guide optical fiber is revealed. The lateral guide optical fiber includes a transparent optical fiber body covered by a refraction layer and a reflector connected with one side of the optical fiber body. Thereby after light emitted into the optical fiber body from one end thereof, it is projected onto the refraction layer and then is refracted downward to be gathered onto the reflector. Then the light gathered is reflected by the reflector and is projected out. Thus the light intensity and uniformity of the optical fiber are increased dramatically by the light gathering and light reflection.
