Abstract

The utility model discloses an incandescent lamp bulb which can prolong service life and can conveniently change the power of the lamp bulb. The lamp bulb comprises two contacts and two filaments, wherein, the two contacts are respectively combined with the two filaments and spiral lamp sockets to form two light emitting circuits which are nutually independent; when the utility model is used, users can only select one light emitting circuit for lighting; after the filament of light emitting circuit is broken, then the other light emitting circuit is used for lighting; so, the service life of the lamp bulb is prolonged, the utilization of other parts of the lamp bulb is increased, and users can select two filament circuits to be switched on simultaneously to increase the power and the brightness of the lamp bulb.

Description

A kind of incandescent lamp bulb

The utility model belongs to ligthing paraphernalia, particularly a kind of incandescent lamp bulb.

The ordinary incandescent lamp bubble is a large amount of ligthing paraphernalias that use in the daily life.Its advantage is photochromic natural harmony, and bulb structure is simple, low price, and installation and use are all very convenient, therefore is subjected to users' welcome deeply.But its shortcoming also is tangible, because incandescent lamp bulb relies on filament heating itself to come luminous, therefore power consumption is bigger, and its life-span is fully by the filament decision, in case filament blow, can not maintain and replace, intact other parts such as glass housing, socket etc. also can only be abandoned, and cause certain waste, and filament is once making the parameter of promptly having fixed filament simultaneously, can only more change the bulb or adopt circuit control for the user who requires the different brightness of conversion, very inconvenient.

The purpose of this utility model provides a kind of incandescent lamp bulb of conversion bulb power easily that increases the service life also.

The purpose of this utility model is realized by following technical scheme:

A kind of incandescent lamp bulb, it comprises screw lamp base 1, glass housing 2, its special improvements are: it has two contacts, and contact 3 and contact 4 also have two filaments, filament 5 and filament 6, above-mentioned two contacts are positioned at the top of screw lamp base 1, separate with insulating material between two contacts, and above-mentioned two filaments are positioned at the central authorities of the glass housing 2 of bulb, contact 3, filament 5 and screw lamp base are formed a luminous loop, and contact 4, filament 6 and screw lamp base are formed another luminous loop.

Above-mentioned incandescent lamp bulb, described two filaments go to upper and lower two-layer distribution in glass housing 2.

After adopting said structure, can connect a luminous loop wherein in use, after the filament in this loop damages, connect another luminous loop again, can make the life-span of bulb prolong one times like this, improved the utilance of bulb miscellaneous part, can also connect two illuminating circuits simultaneously, bulb power is strengthened, increase brightness, the user can select to use different brightness thus.The utility model is simple in structure, only needs to improve a little on the ordinary incandescent lamp bubble to get final product.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A cutaway view of Fig. 1.

As we can see from the figure, the utility model steeps and indistinction with ordinary incandescent lamp on overall structure, and its improvements are contact and filament, and it is divided into two parts with original contact.Be shown as contact 3 and contact 4 among the figure, their position is mutual insulating between them also at former bulb contact position.Filament also adopts two, each contact portion is with wherein filament and screw lamp base 1 are formed a luminous loop, show among the figure, contact 3, filament 5 are formed a loop with screw lamp base, and contact 4, filament 6 and cap 1 are formed another loop, these two luminous loops are independent mutually, filament 5 and filament upper and lower two-layer semi-circular arrangement in 6 fens in glass housing 2.Following several selection can be arranged: can select for use two filaments simultaneously luminous luminous when using this bulb with single filament as need conversion brightness of illumination, can directly screw in this bulb in the socket when selecting big brightness for use, contact 3 and contact 4 are connected with external power supply simultaneously, two luminous loops are all luminous, and be the high-power and high-luminance bulb this moment; When selecting low-light level for use, a contact of this bulb can be screwed in socket with the topped back of insulating tape, external power supply only contacts with one of them contact, has only a luminous loop luminous, is low-light level, low-power bulb.When the single loop of selecting low-light level for use is luminous, also can prolong the useful life of bulb, when luminous loop after after a while, filament damages, take bulb this moment, taking off topped insulating tape on another contact, screw in socket again and use, promptly starts working in another luminous loop, such bulb just can extend working time greatly, thereby has also improved the utilance of parts such as socket, housing.
