PROBLEM TO BE SOLVED: To surely prevent peeling-off of a cover heater by a method wherein a transparent tape material is wound around an entire circumference of a fluorescent lamp cover including the cover heater. SOLUTION: Transparent tape materials 96, 96 are wound around entire circumferences of both ends in a longitudinal direction of a fluorescent lamp cover to which a cover heater 92 is adhered. The tape material 96 is made such that adhesive agent is coated to one surface of a PVC film of with a thickness of about 0.01mm, resulting in that it is full of weatherability and heat-resistance, and an adhesive at one surface is adhered to outer surfaces of the cover heater 92 and the fluorescent lamp cover 49 and wound around there. Then, the fluorescent lamp cover 49 is engaged with clips 97, 97 at the position of each of the tape materials 96, 96, and the fluorescent lamp cover 49 is fixed to a reflection plate through clips 97, 97. With such an arrangement as above, the tape material 96 is present among the fluorescent lamp cover 49, the cover heater 92 and the clip 97. Owing to this fact, the tape is hardly peeled off and a dropping of the cover heater 92 can be effectively prevented. |
