CIRCULAR FLUORESCENT LAMP

摘要

PURPOSE:To avoid the breakdown of a circular fluorescent lamp by providing a thin part at an appropriate position along the outer side surface of the bulb. CONSTITUTION:A thin part 3 is provided along the outer side surface 2 of a bulb 1. Here, the location of the part 3 should be more than 5cm apart from a tube end 4, along the outer side surface 2. A number of thin parts 3 may be provided along the outer side surface 2 of the bulb 1. Consequently, the intentionally safe provision of thin parts 3 at relatively safe positions of the bulb 1, makes the bulb 1 strong and unbreakable.
