Abstract: PURPOSE:To eliminate the outflow of sodium from a luminous tube in lighting and to prevent the change of the color temperature, by enclosing the luminous tube with a cylindrical light-permeable coverage which absorb ultraviolet rays, and maintaining the luminous tube in an outer tube which is kept at a high vacuum. CONSTITUTION:A luminous tube 1 with a pair of electrodes 2a and 2b, sealing a metallic haloid including mercury, a rare gas, and sodium therein, is enclosed by a cylindrical light-peameable coverage 7 of a ultraviolet ray absorbing material such as Pyrex glass, and an enclosing plate 8 made of mica.

In this case, a thermocouple is installed in a lower temperature or intermediate temperature area 5a or 5b of a main burner (or pilot burner) 1 while avoiding a flame generating part 4a, burner tip part 4b which becomes extremely hot due to the contact of the flame, and the vicinity 4c of the burner in the furnace which surely becomes extremely hot due to a flame atmosphere or the generation of the flame.  Then, when a difference between the detected temperature and the previous detected temperature becomes lower than a set temperature, i.e., when a temperature displacement amount is large, judgement of a misfire is given.
