Abstract
A lighting device having prism grating microstructure includes a light tube body and a light source board. The light tube body includes an installation base and a light cover connected to each other to form an accommodating space. The light cover includes a first microstructure portion, a second microstructure portion and a light concentrating portion. The first microstructure portion and the second microstructure portion are disposed at the two sides of the light concentrating portion respectively, so the first microstructure portion and the second microstructure portion are connected to each other via the light concentrating portion. The light source board is disposed on the installation base and in the accommodating space. The first microstructure portion has a plurality of first prism steps orderly arranged and the second microstructure portion has a plurality of second prism steps orderly arranged. The first microstructure portion is symmetric to the second microstructure portion.
