照明すべき側に面して設けられる。(Example) Next, an example of the present invention will be described with reference to the drawings. 1 and 2 show an example of a lighting device 10 according to the present invention, in which numeral 11 is an illumination light and 12 is a protection tube surrounding it. The protection tube 12 is a transparent cylinder made of glass, resin, or other material, and is usually cylindrical. Reference numerals 13 and 14 are sockets provided at the ends of the lamp. The protective tube 12 also serves to protect these sockets. As FIG. 2 clearly shows, the protective tube 12 of this lighting device has a groove 15 extending longitudinally at least half way in cross section, preferably on the inner surface as shown.
is formed, and the cross section of that part has a sawtooth shape. It is sufficient that such a groove 15 is formed over about half of the width, that is, 180 degrees in cross section, but may be formed over a wider area depending on the case.
The portion of the protective tube 12 where the groove 15 is located is provided facing the outside or the side to be illuminated.
また、溝１５は第３図に示すように、保護管１
