Abstract
A lighting fixture having a generally cuboid main housing elongated in a longitudinal direction, a light source for emitting light, and a solid light tube of light-permeable material mounted in the main housing for receiving the light. The light tube is elongated in the longitudinal direction and includes a light-emitting surface having generally linear, elongated prisms extending in the longitudinal direction for refracting the light. The lighting fixture also includes a reflecting surface elongated in the longitudinal direction and at least partially facing the light-emitting surface for receiving the refracted light and reflecting the refracted light.
