Abstract
The utility model discloses an electric bicycle bulb which comprises a lamp base, a filament bracket, a glass bulb fixed at the upper part of the lamp base, a filament transversely arranged on the filament bracket, a glass stem fixed at the bottom center of the lamp base, a Dumet wire A and a Dumet wire B respectively connected with the lower ends of the fulcrum bar A and the fulcrum bar B of the filament bracket and a filament support bar with the upper end in the shape of a hook and nested on the middle part of the filament. Due to the support of the filament support bar, the drooping of the filament resulting from heating extending and softening after electrifying is reduced, therefore, the shape of the filament is relatively stabilized; moreover, the filament is not easy to jitter and the adjacent helicoids arranged at the center of the filament do not join together so as to avoid short circuit and uneven light mode, etc., thereby prolonging the service life of the filament.
Description
Technical field
The utility model relates to a kind of automobile-used bulb, and the antidetonation bulb that particularly a kind of electric bicycle is used belongs to lighting technical field.
Background technology
Along with the raising of development of times and living standards of the people, electric bicycle more and more is subjected to people's welcome as a kind of quick, laborsaving, free of contamination walking-replacing tool.Because the 48V direct voltage of electric bicycle bulb is greater than the 24V direct voltage of automobile, motorcar bulb, thereby the tungsten filament diameter of electric bicycle bulb is less than the tungsten filament diameter of automobile, motorcar bulb.When the electric bicycle bulb travels under the energising illuminating state, the high temperature more than 2000 ℃ during filament light-emitting makes its extension deliquescing sagging, under the vibrations that electric bicycle travels, make the adjacent bung flange of filament that the phenomenon of doubling-up take place easily, cause short circuit, bright spot may appear in short circuit place, the bright spot place occurs astigmatism is gathered in certain a bit, causes light type non-uniform phenomenon; Simultaneously, the molten point at bright spot place reaches one regularly, burns filament easily, causes the useful life of electric bicycle bulb shorter, influences the electric bicycle driving safety at night.
Summary of the invention
In order to improve the useful life of existing electric bicycle bulb, to improve the safety guarantee of electric bicycle night running, that the utility model provides is a kind of simple in structure, durable in use, manufacturing cost is lower and electric bicycle bulb that can antidetonation.
The utility model is achieved by the following technical programs:
A kind of electric bicycle bulb comprises glass bulb, filament, glass stem, lamp holder, filament support, Dumet wire A and Dumet wire B; Described glass bulb is fixed on the top of lamp holder, the central authorities of described filament are spirality, and two ends are linear, and this filament is horizontal on filament support, its two ends are separately fixed on the top of the pole A of filament support and pole B, and the lower end of described pole A and pole B is separately fixed at the top of glass stem; Described glass stem is fixed on the bottom center of lamp holder, and the upper end of described Dumet wire A and Dumet wire B is connected with the lower end of pole B with pole A respectively; Also comprise upright filament support bar, the upper end of described filament support bar becomes hook-type to be enclosed within the middle part of filament, and the bottom of this filament support bar is fixed on the top of glass stem.
The purpose of this utility model can also further realize by following technical measures
Aforesaid electric bicycle bulb, wherein said filament support bar are molybdenum filament.
Because adopted above technical scheme, electric bicycle bulb of the present utility model has following beneficial effect:
The upper end of electric bicycle light bulb filament support bar of the present utility model becomes hook-type to be enclosed within the middle part of filament, has held filament, has reduced the filament heating power and has extended the sag of chain of deliquescing, the relatively stable shape of filament.The vibrations though electric bicycle has travelled, when bulb was lighted, because the support of filament support bar has been arranged, filament was difficult for rocking, and the adjacent bung flange of filament central authorities also is difficult for producing doubling-up and causing short circuit, the unequal phenomenon of light type, thereby the life-span of prolongation bulb.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, electric bicycle bulb of the present utility model comprises glass bulb 1, filament 2, glass stem 3, lamp holder 4, filament support 5, Dumet wire A61 and Dumet wire B62.Be fixed with glass bulb 1 on the top of lamp holder 4; Filament 2 is horizontal on filament support 5, and its two ends are separately fixed on the top of the pole A51 of filament support 5 and pole B 52; This filament 2 is a central spiral shape, the rectilinear structure in two ends; The filament support 5 of present embodiment is up big and down small " V " shape, and the pole A51 of this filament support 5 is fixedlyed connected with filament 2 two ends respectively with the top of pole B 52, and the lower end of pole A51 and pole B52 is separately fixed at the top of glass stem 3; Glass stem 3 is fixed on the bottom center of lamp holder 4, and the upper end of Dumet wire A61 and Dumet wire B62 is connected with the lower end of described pole A51 and pole B52 respectively; Filament support bar 7 is vertical, and material is the molybdenum filament of anti-2600 ℃ of high temperature, and its upper end becomes hook-type to be enclosed within on the spirality at filament 2 middle parts, and its underpart is fixed on the top of glass stem 3.Though vibrations are arranged when electric bicycle travels, when bulb is lighted, because the support at 7 pairs of horizontal filament 2 middle parts of upright filament support bar is arranged, make filament 2 be difficult for rocking, the adjacent bung flange of filament 2 central authorities also is difficult for producing doubling-up and causes short circuit, the unequal phenomenon of light type, has prolonged the useful life of electric bicycle bulb.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
