    • PURPOSE:To prevent deterioration of a luminous body so as to use it in a long time by sealing up the luminous body to generate face emission at adding electric field in a transparent or translucent pipe having ultraviolet-ray absorbing property through elastic plugs on both ends of the pipe. CONSTITUTION:An upper pipe 1 is formed out of a transparent or translucent synthetic resin pipe 1A having ultraviolet-ray absorbing property, and a luminous body 10 of semiconductor to generate face emission at adding electric field is formed into a belt shape and provided in the pipe 1A. Plugs 11, 12 made of elastic substance such as silicon rubber are formed into cylinders having step parts on the outer face, and provided with grooves 11a, 12a for fitting to the end parts of the luminous body 10 on the inside. Both ends of the pipe 1A are sealed up with the plugs 11, 12, and fitted to joints 13 connected to projecting pieces 6a, 7a projectingly provided on a head pipe 6 and a seat lug 7. A driving inverter 15 to apply high electric field on the luminous body 10 is provided in the plug 12, and connected to a dynamo for bicycle through a cord. The driving inverter 15 supplies AC voltage of higher voltage and frequency than the output of the dynamo, and high electric field can be obtained.
