Abstract

See full text

A light tube includes a tube body, at least one light emitting diode, and a transparent cover. The light emitting diode is assembled with the tube body. The transparent cover is disposed on the tube body to cover the light emitting diode and has a roof portion and two side arm portions. A first microstructure region and a second microstructure region are formed on a surface of the roof portion corresponding to the light emitting diode. The second microstructure region extends from two ends of the first microstructure region. A third microstructure region is formed on a surface of each side arm portion corresponding to the light emitting diode. A microstructure density of the second microstructure region is less than or equal to a microstructure density of the first microstructure region, and is greater than or equal to a microstructure density of the third microstructure region.
