Abstract
The utility model relates to a long service lamp bulb. A common lamp bulb is provided with one filament; when the filament is burnt, the lamp bulb becomes a waste product. More than two sets of filaments are arranged in the lamp bulb of the utility model, and a power supply changeover switch is arranged at the position of a lamp holder; when one set of the filaments is burnt, the lamp bulb can be continuously used by switching on another set of the filaments through the power supply changeover switch; thus, the utility model has the advantages of capability of prolonging the service life of the lamp bulb, energy saving and low cost.
Description
The utility model relates to a kind of long-life bulb that is used for normal lighting.
The filament of the common bulb of people's use is at present formed by a filament, behind the filament blow, even vitreum and lamp holder are excellent, but stops immediately the useful life of bulb, and the life-span of filament is promptly determining the life-span of bulb.
The purpose of this utility model is to provide a kind of durable, long-life bulb.
The utility model is formed light bulb filament by two or two above filaments, and the lamp holder is provided with a change over switch, has only a filament to come into operation during use, by change over switch, another root filament is come into operation behind filament blow.
Advantage of the present utility model is in an incandescent lamp bulb two or more filaments to be housed, and during use, has improved the useful life of whole bulb, saves a large amount of resources, has bigger economic benefit and social benefit, and is with low cost, is beneficial to popularization.
