The present invention relates to an optical pipe lighting device. In order to solve an inefficiency of an incandescent lamp and a fluorescent lamp that have been used for securing a view in a dark place of a house or a street, an LED lighting consuming less power and having high efficiency for long-term usage is developed. However, lighting using an existing LED has limitations on shaping and difficulties in spreading light from the LED in all directions. The optical pipe lighting device of the present invention spreads light emitted from the LED efficiently, evenly and far, and is capable of being made into various shapes not having limitations to the place and position of installation. In addition, the optical pipe lighting device enables the light emitted from the LED to be focused on a something important or spot requiring attention, and can be extended in a lengthwise direction for lighting a dangerous spot and a curved section on the road. |
