A straight line type industrial illuminator is provided to concentratedly emit illumination light to a lower portion of a light pipe, and improve illumination efficiency and transmission efficiency. A straight line type industrial illuminator includes a reflection plate(R), an end cap(79), and a reflector(80). The reflection plate is incorporated in one side of an inner circumference surface of a light pipe(70) in a lengthwise direction of the light pipe and reflects illumination light in the light pipe to the other side of the inner circumference surface of the light pipe. The end cap seals the other end portion of the light pipe with the reflection plate. The reflector is integrally fixed to the end cap and is inserted into the other end portion of the light pipe. The reflector reflects the illumination light guided to the other end portion of the light pipe to one end portion of the light pipe. |
