Abstract
A double filament light adjusting incandescent lamp bulb consists of a lamp holder, a glass shell, a wick, a normal bright filament, a standby filament and a switch. The standby filament is arranged in the glass shell; the standby filament is connected in series with the switch and with the two ends of the normal bright filament; the switch is fixed in the lamp holder; a switch hole is arranged on the lamp holder. The normal bright filament is used for lighting normally; when the normal bright filament is broken, the switch in the lamp holder is closed; thereby the standby filament lights; and the bulb can still be used; in the normal cases, the switch is closed to make the two filaments light to increase the luminance at the same time; the luminance resumes when switching off the switch. The utility model can make one bulb used two times, and has the emergency and luminance adjustment function concurrently, thereby reducing the pollution and saving the raw materials. The utility model has the advantages of the simple structure, the safe use, which is suitable for the commercial production.
Description
Technical field the utility model relates to a kind of lighting device, especially relates to the incandescent lamp bulb of preparing and carrying with the adjustable brightness of filament.
The present known incandescent lamp bulb structure of background technology is made up of lamp holder, glass bulb, wick, filament etc., and energising back filament is red-hot luminous in glass bulb, thereby produces illuminating effect.Filament breaking then whole bulb can not be used again, and other part except that filament is then excellent, still has use value, and filament only accounts for a very little part in the whole bulb cost, can only scrap with filament, not only cause the lot of materials waste, also bring environmental pollution simultaneously.Lighting device just had tens incandescent lamp bulbs to scrap in only domestic 1 year still based on incandescent lamp bulb at present, and its waste is polluted and well imagined.The illumination incandescent lamp bulb is monofilament design now, does not also have function emergent and that regulate brightness, can not satisfy actual needs, uses inconvenience.
Summary of the invention is scrapped in order to overcome existing illumination incandescent lamp bulb filament breaking whole bulb, monofilament design does not have deficiency emergent and adjusting brightness function, the utility model provides a kind of incandescent lamp bulb, this bulb not only has standby filament, overcome the filament breaking whole bulb and must scrap the deficiency of replacing, can also carry out the folded turn reducing of filament easily as required and change, regulate brightness.
The technical scheme that its technical problem that solves the utility model adopts is: lamp holder, glass bulb, wick, normal bright filament sequential combination, one standby filament is set on the wick in glass bulb, one end of standby filament is electrically connected with normal bright filament one end, and switch is electrically connected with the normal bright filament other end in the other end serial connection lamp holder of standby filament.When normal use, normal bright filament light-emitting; When normal bright filament breaking, with switch closure in the lamp holder, standby filament light-emitting; When normal use need increase brightness, can be with switch closure in the lamp holder, make normal bright filament, standby filament simultaneously luminous, increase brightness, disconnect when recovering brightness that switch gets final product in the lamp holder.
The beneficial effects of the utility model are, the bulb other parts are scrapped, can enable standby filament utilize again again luminous, two usefulness in bulb top, have emergency function concurrently, can start standby filament simultaneously as required and increase brightness.Aforesaid operations need cut off the power supply and take off bulb and just can carry out, and is safe in utilization.Simple in structure.
