<p>PROBLEM TO BE SOLVED: To provide the recyclable bulb and fluorescent lamp. SOLUTION: A spare of a filament 2 being apt to be failed and troubled in a group of parts of the bulb and the fluorescent lamp are provided inside of the bulb and the fluorescent lamp, and a base 8 and a plug connecting part capable of being selectively energized, are formed. By selecting the energization, the other parts can be recycled, and the life can be elongated. That is, two filaments are prepared for one filament 2 between two lead wires 4 of a conventional bulb, whereby two electric passages are formed by the lead wire 4 and a Dumet wire 5 for each electricity passage of one side. The bulb is divided into two on the way, and the divided bulbs are connected by a plug-type circuit 13, so that only one circuit is energized, and the other circuit is used when the circuit is failed or troubled.</p> |
