Abstract
The utility model relates to an improved bulb for a motor vehicle, which comprises a lamp holder body, a glass lamp shell, positive and negative electrodes and filaments which are connected with the positive and negative electrodes. The utility model is characterized in that the positive and negative electrodes are respectively bent into electrode rods which present an L-shaped structure, and at least a filament is vertically connected between transverse rods formed after the positive and negative electrodes are bent. Because the utility model adopts a structure that a plurality of pairs of the positive and negative electrodes in a star-shaped structure are arranged in the glass lamp shell, and a plurality of filaments are vertically connected with each pair of the positive and negative electrodes in parallel, the utility model has the advantages of long service life and good reliability. A driving safety hidden danger brought by the sudden burning of a single-filament bulb can be effectively avoided, and the running safety of the motor vehicle at night is ensured. The utility model also has the characteristics of simple structure and easy manufacture and fabrication.
Description
Technical field
The utility model relates to a kind of bulb of automobile-use, particularly a kind of improved motor vehicle bulb.
Background technology
At present, the bulb of used various models on the motor vehicle, its wick generally all are the single filament structures.When vehicle in the night running process, in case the filament of bulb is blown suddenly, this lamp has just lost its illumination functions, thereby has directly influenced driver's traffic safety.Chinese patent ZL00125475.8 discloses " a kind of high-reliability double-filament vehicle lamp ", the wick of this auto lamp is by top while and the identical filament of di-root at positive and negative electrode, reaches the purpose that the bulb that prevents the single filament structure is burnt afterwards influences driver's traffic safety.But, the motor vehicle bulb of this structure is owing to be by two filaments being divided on the both sides that embowment is fixed in the positive and negative electrode top, after making its central filament blow, surplus silk after being blown is run into another root filament of offside easily, cause the change of the work resistance of another root filament easily, cause another remaining filament to burn because of electric current is excessive.Thereby directly influence whole bulb useful life and driver's traffic safety.
Summary of the invention
The purpose of this utility model is to provide a kind of longer service life, better reliability, and modified model motor vehicle bulb simple in structure.
The technical solution of the utility model is achieved in that
A kind of improved motor vehicle bulb, comprise lamp holder, glass lamp housing and positive and negative electrode and be connected in filament on the positive and negative electrode, its characteristics are that described positive and negative electrode is the " electrode stem of " " structure, and vertically be connected with at least one filament between the cross bar that forms in positive and negative electrode bending back for being bent into respectively.
For making the utility model syndeton more simple, convenient, and further prolong its useful life, " the relative embedding of the positive and negative electrode of " " structure becomes to be by being to be provided with at least one pair of in the above-mentioned glass lamp housing
The positive and negative electrode bar of structure, and between each upper and lower cross bar that positive and negative electrode bending back is formed, vertically be connected with at least one filament.As: can in the glass lamp housing of bulb, be provided with a pair of or being more than two pairs or two pairs according to the needs of the bulb of different model or dissimilar motor vehicle
The positive and negative electrode of structure.Meanwhile, between the upper and lower cross bar that forms after each bending, also can and connect filament more than one or two or two to positive and negative electrode.
The utility model is because employing is provided with many to being in the glass lamp housing of bulb
The positive and negative electrode of structure and vertical and be connected to the structure of Multi-filament on to positive and negative electrode at each, make longer service life of the present utility model, better reliability, thereby the bulb of effectively having avoided single filament blows the traffic safety hidden danger of bringing suddenly, has guaranteed the fail safe of motor vehicle at night running.And simple in structure, the easy characteristics of processing and fabricating that the utility model also has.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings

Fig. 2 is the side structure schematic diagram of the utility model Fig. 1.
Embodiment
As shown in Figures 1 and 2, a kind of improved motor vehicle bulb described in the utility model comprises lamp holder 1, glass lamp housing 2 and positive and negative electrode 3,4 and is connected in filament 5 on the positive and negative electrode 3,4.Exist useful life short for effectively solving existing bulb, cause the problem of driving at night security incident easily, positive and negative electrode described in the utility model 3,4 is the " electrode stem of " " structure, and vertically be connected with at least one filament 5 between the cross bar that forms in positive and negative electrode 3,4 bending backs for being bent into respectively.Like this, make longer service life of the present utility model, better reliability, thereby effectively avoided the bulb of single filament to blow the traffic safety hidden danger of bringing suddenly, guaranteed the fail safe of motor vehicle at night running.For making the utility model syndeton more simple, convenient, and further prolong its useful life, " positive and negative electrode 3, the 4 relative embeddings one-tenth of " " structure are by being to be provided with at least one pair of in the described glass lamp housing 2
The positive and negative electrode bar of structure, and between each upper and lower cross bar that positive and negative electrode 3,4 bending backs are formed, vertically be connected with at least one filament 5.As: can in the glass lamp housing 2 of bulb, be provided with a pair of or being more than two pairs or two pairs according to the needs of the bulb of different model or dissimilar motor vehicle
The positive and negative electrode 3,4 of structure.Meanwhile, between the upper and lower cross bar that forms after each bending, also can and connect filament 5 more than one or two or two to positive and negative electrode 3,4.Figure 1 and Figure 2 and for example, present embodiment adopt and are provided with two pairs of relative embeddings become to be in glass lamp housing 2
The positive and negative electrode 3,4 of structure, and between each upper and lower two cross bar that positive and negative electrode 3,4 bending back is formed, vertically be connected with two filaments 5 and be structure.
