ABSTRACT:
An illumination device includes a plurality of light tubes arranged in a substantially V-shaped manner, and at least one reflector located adjacent to the light tubes. The reflector has a semi-circular shape directed in an axial direction of the light tubes. Thus, the light reflected from the reflector is not directed toward the incident direction of the light tubes, so that the light reflected from the reflector is projected outward in a straight manner without being blocked and sheltered by the light tubes, thereby decreasing the optical loss to the minimum.
