CN2057031U - Dual- or multi-filament lamp - Google Patents

Abstract

The utility model provides a dual-filament or multi-filament lamp. One set of filaments of the utility model is working filaments. Other filaments are spare filaments. When the working filaments are burnt out, one set of spare filaments is connected with a filament changed electrode (4), and the lamp can be continuously used. Therefore, the service life of a dual-filament lamp can be extended by one time. The service life of a dual-filament fluorescent lamp can be extended by 1-2 times. If the dual filaments of the filament lamp are connected in parallel, the brightness of the lamp can also be changed. The service life of a multi-filament lamp can be extended in multiples. The brightness of the multi-filament lamp can be varied by a multi-stage mode. The lamp holder of the lamp is still matched with an original corresponding single filament lamp holder.

Description

Dual- or multi-filament lamp

The utility model belongs to illumination with mariages or multi-filament incandescent lamp and mariages or multifibres fluorescent lamp.

In case the filament of incandescent lamp and fluorescent lamp is the heart component filament blow of lamp, lamp just can not re-use; For fluorescent lamp, even filament is disconnected, when lamp uses too for a long time, when making the filament electron emission ability too weak, light is too dark, can not normally use, so the age limit of filament the useful life of lamp.Patent Office of the People's Republic of China's utility model patent notification number provides a kind of mariages or multi-wire incandescent lamp for the patent of GG85200794, but this bulb needs multiple special lamp cap, screw socket, socket and conversion socket etc. supporting, could use.Increase these parts peculiars and not only use inconvenience, and it is a lot of that production cost is increased, be not suitable for popularizing in an all-round way and use.

The purpose of this utility model is that a kind of mariages or multi-filament incandescent lamp and fluorescent lamp will be provided.The lamp holder of this lamp is fixed, and still uses the lamp socket (socket that comprises screw socket and plug adapter and fluorescent lamp) of former corresponding monofilament lamp, and the life-span of this mariages incandescent lamp can prolong one times, and the life-span of this mariages fluorescent lamp can prolong 1 to 2 times.In case of necessity, incandescent lamp also can change the brightness of lamp.By this principle, increase the corresponding increase of life-span meeting of filament, lamp again, the grade that incandescent lamp changes brightness also can increase.

Do to describe in detail below in conjunction with accompanying drawing.

The utility model comprises conventional lamp holder (6), sealing cover (7) and two filament or organizes filament more.

Twin-filament lamp of the present utility model realizes in the following manner, and the distance between two groups of filaments is not determined can not collide another group filament behind one group of filament blow wherein. One group of filament is the work filament, and another group is spare heater. One end of work filament and an end of spare heater have one to share lead-in wire (3), after being drawn by the horn mouth of lamp, with an electrode (5) welding of lamp holder; The lead-in wire (1) of the work filament other end after horn mouth is drawn, passes the aperture of lamp holder two interpolar insulators, joins with another electrode (4) again, and electrode (4) can be made a stud bolt so that change and being connected of heater lead. The lead-in wire of the spare heater other end (2) is also drawn by horn mouth, passes the aperture of the insulator of lamp holder, and another aperture by insulator inserts again, and this lead terminal can arbitrarily not slided. During normal operation, lamp holder inserts corresponding monofilament lamp lamp socket, and plugged only has the work filament through the two poles of the earth and power connection, so only have the work filament light-emitting. In case behind the work filament blow, only need spare heater is gone between (2) by taking out in the lamp holder insertion aperture, insert again and change an electrode (4), then after the energising, spare heater is luminous. According to this principle, the life-span of this mariages incandescent lamp can double, this Diplonema double-thread florescent lamp, because there are work filament and spare heater in two ends, work filament that might two ends blows earlier, also two groups of filaments of possibility one end blow earlier, so the life-span of fluorescent lamp may increase by 1 to 2 times. The white lamp of this mariages if need the brightness of increase lamp, only needs an electrode (4) is changed in two simultaneously accesses of independent lead-in wire of filament, then increased power is one times, the corresponding increase of brightness, in order to simplify working process, two electrodes of socket lamp and fluorescent lamp one end also can all adopt bolt.

By this principle, if more than one of standby filament has just constituted multi-filament lamp, the corresponding growth of the life-span of multi-filament lamp, incandescent lamp can change the grade of brightness also can corresponding suitable increase.

The utility model applicability is very strong, and is simple in structure, is easy to make, and cost is not high, is applicable to the mass production and marketing use.
