Abstract

The utility model discloses a vehicle halogen lamp with a metal lens hood, comprising a lamp holder and a bulb shell connected with the lamp holder, wherein a tungsten wire is arranged in the bulb shell, and the metal lens hood is arranged at the top part of the outer side of the bulb shell. Because the metal lens hood is arranged at the top part of the bulb shell, the vehicle halogen lamp can reduce stray lights irradiated outwards by the halogen lamp, enable a light shape of the halogen lamp to be more standard, efficiently improve the utilization rate of the lights and enable vehicle driving to be safer.

Description

A kind of automobile Halogen lamp LED with metal light shields

Technical field

The utility model relates to the auto lamp technical field, especially a kind of automobile Halogen lamp LED with metal light shields.

Background technology

The automobile front of prior art generally adopts Halogen lamp LED as dipped beam or far lighting, for the illumination ejaculation that guarantees this kind Halogen lamp LED goes to have light shape preferably afterwards, can not astigmatism occur and make the vehicle that the opposite travels or the pedestrian in roadside feel that too dazzling situation takes place, see also shown in Figure 1, all be coated with one deck black shading overlay 2 ' at present in the outside top of this automobile Halogen lamp LED cell-shell 1 ', this kind black shading overlay 2 ' can effectively shelter from the veiling glare that sends from automobile Halogen lamp LED cell-shell 1 ' middle body, further improve the light efficiency of car bulb, make light type standard of comparison, but this black shading overlay 2 ' generally adopts chemical substance to form, stick to for a long time on the cell-shell 1 ' and may produce corrosiveness cell-shell, and under the situation that the automobile Halogen lamp LED illuminates for a long time, temperature in the cell-shell 1 ' can raise, overheated temperature can make its evaporation or dry and cracked with the chemical substance baking of black shading overlay 2 ', this evaporation back chemical gas may cause certain damage to the light fixture in the headlight for vehicles on the one hand, still stick to the overlay on the cell-shell 1 ' on the other hand because there is the crack in dry and cracked meeting, light in the cell-shell 1 ' can form veiling glare in this crack of printing opacity, influences its result of use.

Summary of the invention

The purpose of this utility model is to overcome the problem that the dry and cracked easily or volatilization of the black shading coating of prior art influences the Halogen lamp LED result of use, provides a kind of and makes the long-term use of this Halogen lamp LED still can better improve the automobile Halogen lamp LED of the band metal light shields of light utilization efficiency effect.

For realizing above purpose, the utility model has been taked following technical scheme: a kind of automobile Halogen lamp LED with metal light shields, the cell-shell that includes lamp holder and be connected with this lamp holder is provided with tungsten filament in this cell-shell, is provided with metal light shields at the top in the described cell-shell outside.

Transparent cell-shell supports light shield, in the bulb top coating coating is arranged with respect to prior art, the utility model is by being provided with metal light shields at the cell-shell top, make the light that sends in the cell-shell have light type preferably, can effectively prevent the appearance of astigmatism, improve traffic safety, further improved the utilization rate of light, prolonged the service time of bulb.

Cell-shell and outside bulb shell in described cell-shell comprises, in the cell-shell, outside the cell-shell, this metal light shields was arranged at the top in the described outside bulb shell outside in described outside bulb shell was set in described tungsten filament was arranged at, and this outside bulb shell bottom is connected with lamp holder.Because the cell-shell of the far and near light automobile Halogen lamp LED of prior art has only one deck, in use, not only the temperature on cell-shell surface can be than higher, and UV also is easy to radiate and causes the damage of headlight or easily make other accessories of headlight be subjected to heat ageing etc., therefore by double-deck cell-shell is set, make the anti-UV of this Halogen lamp LED efficient 100%, this clear glass intercepts UV, can prevent that UV is to the damage of automobile front light fixture and aging.

In described, charged into xenon in the cell-shell.Being full of in the inner layer glass bulb has xenon, makes it luminous brighter, and lamp power rises to present 100 to 120W by original 50 to 60W.

On described metal light shields, offer louvre, this louvre with described in space between cell-shell and the outside bulb shell communicate.The heat between the cell-shell and outside bulb shell is set in effective assurance discharges from louvre of louvre, the more effective radiating effect that has guaranteed to replant double-deck Halogen lamp LED has prolonged service life of bulb.

The utility model compared with prior art, have following advantage: automobile Halogen lamp LED of the present utility model is owing to be provided with metal light shields at the cell-shell top, can reduce the veiling glare of Halogen lamp LED to external exposure, make the light type standard more of Halogen lamp LED, effectively raise the utilization rate of light, make driving safer.

The specific embodiment

Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.

Embodiment:

See also Fig. 2 and shown in Figure 3, a kind of automobile Halogen lamp LED with metal light shields, present embodiment automobile Halogen lamp LED is the far and near light automobile Halogen lamp LED of power 55W, the cell-shell 1 that it includes lamp holder 4 and is connected with this lamp holder 4, this cell-shell 1 is installed on the extended line of lamp holder 4 axis, and cell-shell 11 and outside bulb shell 12 in cell-shell 1 comprises, outside bulb shell 12 are set in outside the interior cell-shell 11, be provided with the tungsten filament 2 and the associated lamp lead-in wire of far and near light in being somebody's turn to do in the cell-shell 11, be provided with metal light shields 3 at the top in outside bulb shell 12 outsides.

Further, for promoting lamp power, can in interior cell-shell 11, charge into xenon.

Offer louvre 31 on metal light shields 3, this louvre 31 communicates with space between interior cell-shell 11 and the outside bulb shell 12.

The outside bulb shell 12 of present embodiment is a little more than interior cell-shell 11, and this metal light shields 3 covers on the outside bulb shell 12, and the edge of going to the bottom of light shield is concordant substantially with the top of interior cell-shell 11.

Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
