ABSTRACT:
A lighting fixture for improving the luminance of a lamp tube includes a curved reflecting plate and a lampshade. The lampshade has partition plates with arc surfaces, side plates with inclined planes and end plates with curved surfaces. The lamp tube is disposed at a longitudinal axis of the curved reflecting plate. The reflecting plate reflects the light emitted from the lamp tube and the light reflected from the partition plates to the environment. The side plates are inclined with a certain angle for guiding light, and the end plates with curved surfaces are used to enhance the reflecting light. Thus, light output efficiency is improved and glare is reduced.
