Zusammenfassung:The utility model relates to an over standard rated working voltage bulb. The utility model is characterized in that the length of a filament (1) is added or the material and the cross section of the filament (1) are changed; the added or changed resistance value is 10 percent to 29 percent; more than two supporting rods (2) are added on a fixed disk (3) of the supporting rod. The bulb is used in festoon lamp systems of high buildings, safe lighting systems, signal systems, etc., where the requirements for luminous flux is not high and bulbs are replaced with difficulty under standard rated working voltage; the service life of the utility model can be prolonged by about 400 percent.
