年間に２〜３回の交換が必要であった。Problems to be Solved by the Invention Although incandescent lamps have no problems as far as their function as a display light source is concerned, they are easily damaged because they are mainly composed of glass pulp. Therefore, sufficient care must be taken when handling it. Note that when this incandescent lamp is used exclusively for the above-mentioned device, it is designed to have a considerably longer lifespan than a general incandescent lamp. However, although they are designed to have a long life, their actual lifespan is about 4,000 hours, and maintenance inspections cannot be overlooked, requiring replacement at least two to three times a year.
