Abstract:
A fluorescent lamp comprising:a bulb provided with a pair of electrode coils at both ends thereof, each of the electrode coils mounted between two lead wires held by a bulb-end glass, a means for preventing overheating provided with a glass member and a first and a second metallic pin for supporting the glass member, the first and the second metallic pin being provided not in contact with each other, wherein the means for preventing overheating of the bulb-end glass is mounted between the lead wires located between the electrode coil and the bulb-end glass with one end of each of the first and the second metallic pin connected to the lead wires, respectively, the other end of one of the first and the second metallic pin is projected from the glass member or positioned therein, and the other metallic pin is wound around the glass member with the other end positioned in the glass member so as to be spaced apart from the other metallic pin via the glass member, the other metallic pin extending through a substantially annular portion of the wound metallic pin, the means for preventing overheating melting and retaining its molten state to connect the lead wires electrically just before or after the electrode coil is disconnected.
