LIGHT TUBE |
| 摘要 |
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. |

1. A light tube comprising:
a tube body; at least one light emitting diode assembled with the tube body; and a transparent cover disposed on the tube body to cover the light emitting diode and having a roof portion and two side arm portions, a first microstructure region and a second microstructure region being formed on a surface of the roof portion corresponding to the light emitting diode, the second microstructure region extending from two ends of the first microstructure region, a third microstructure region being formed on a surface of each side arm portion corresponding to the light emitting diode, a microstructure density of the second microstructure region being less than or equal to a microstructure density of the first microstructure region and being greater than or equal to a microstructure density of the third microstructure region.
