Description
Technical field
The utility model relates to the lighting device that a kind of automobile is used, and relates in particular to a kind of 20W～30W high-strength gas discharge automobile lamp.
Background technology
Along with the continuous progress and the development of society, automobile also more and more is subjected to people's attention and likes as the sign of modern society.High intensity discharge metal halide lamp (being generally xenon lamp) as automotive lighting is used because it has the advantage of high light efficiency, high brightness and high-color rendering, more and more is subjected to car steering person's favor.Attraction and the bright spot of high intensity discharge metal halide lamp as car load will be installed in more auto producer commercial city on automobile.The power of the high intensity discharge metal halide lamp that current automotive lighting is on the market used generally all is 35W, and so automobile-used headlight has all advantages of high intensity discharge metal halide lamp.But, because its luminous flux is very high, is easy to generate dazzle and causes light pollution, might cause harmful effect to the driver of other vehicles.And it requires the device that attaches a lot of when installing on car load, cause on automobile when installing difficulty and institute's generation expense very high, spending the high intensity discharge metal halide lamp in addition needs supporting electric ballast to use, and narrow space has proposed very high requirement for the size of ballast in the automobile lamp, but the size of common ballast is all bigger, there are very big difficulty and some potential safety hazards when mounted, so the application of the high-intensity gas discharge lamp of 35W on automobile is subjected to certain restriction.
Though the size of the cell-shell by dwindling electric arc tube can be reduced to the power of high-intensity gas discharge lamp one and be suitable for automobile-used power level, this power level is ~ 25W after tested,, its difficulty of processing of cell-shell that volume is more little and cost are just high more.The discharge space of the cell-shell of existing 35W electric arc tube is of a size of: length 7.65 ± 0.2mm, and height 3.2 ± 0.2mm, if power is reduced to 25W, the discharge space size of Dui Ying cell-shell should be length 5.8 ± 0.2mm, highly 1.8 ± 0.2mm in theory.For in the enterprise that produces 35W high-intensity gas discharge lamp electric arc tube, to produce discharge space tiny 25W high-intensity gas discharge lamp electric arc tube like this and need change and debug big batch facility, cost is higher.And merely the discharge space size of dwindling cell-shell according to theory can only reduce the power of electric arc tube, can not make electric arc tube produce optimal light.So need a kind of about the 25W power level, can bring into play best lighting effect and cheap relatively high-intensity gas discharge lamp of production cost.
Summary of the invention
The purpose of this utility model provides a kind of convenience and install and do not have the low cost of any attachment device, 20W～30W low-power high-strength gas-discharge lamp that lighting effect is good on car load.
For achieving the above object, the utility model is taked following technical scheme:
The utility model is connected and fixed institute by 2 and lamp sockets 5 of a high intensity discharge metal halide lamp hair bubble by fixture 11 and constitutes.High intensity discharge metal halide lamp hair bubble 2 comprises as the quartz glass tube 4 of external shell and is sealed in electric arc tube 3 in the quartz glass tube.Electric arc tube 3 comprises 2 electrodes 14,2 are mutually the diameter contraction at 180 degree angles and the sealing-in neck 15 of sealing, the airtight discharge space 16 that constitutes by two sealing-in necks 15, electric arc tube 3 and quartz glass tube 4 melt the formation space 18 of being honored as a queen by the envelope neck 17 that contracts, between 2 electrodes 14 is 3.0mm～4.5mm apart from Ea, the length C of discharge space 16 is 6.0mm～8.1mm, and height H is 1.5mm～2.6mm, can vacuumize or stuffed heat insulated gas in space 18 in the space 18.
The utility model innovative point is the design of concrete parameter and the design in space 18, and the internal structure of high-intensity gas discharge lamp and electric arc tube and circuit structure can adopt prior art.
Further preferable range of the present utility model is: when vacuum was pumped in the space between quartz glass tube and the electric arc tube 18, the discharge space 16 of cell-shell was of a size of on the electric arc tube: length 7.65 ± 0.4mm, height 2.1 ± 0.4mm; When the space between quartz glass tube and the electric arc tube 18 was injected into insulated gas, the discharge space 16 of cell-shell was of a size of on the electric arc tube: length 7.0 ± 0.4mm, height 2.0 ± 0.4mm.
The shape of the above discharge space can be spherical, ellipsoid shape or tubulose.
The above insulated gas can be argon gas or nitrogen, perhaps the mist of argon gas and nitrogen.
With the 25W lamp is example, require the bulb dimensions reason littler of 25W electric arc tube to be in the prior art: to have air in process of production and sealed up for safekeeping in the space between quartz glass tube and electric arc tube than the bulb dimensions of 35W electric arc tube, bigger bulb dimensions is also very fast by the speed that air dispels the heat, operating temperature when making gas discharge in the cell-shell can not remain on desired level, so size that need be by dwindling cell-shell is to reduce the radiating rate of cell-shell, the operating temperature when guaranteeing gas discharge was unlikely to low.The utility model is by being evacuated the space between quartz glass tube and the electric arc tube, or charge into the mode of insulated gas to this space, make the heat on the cell-shell distribute slack-off, even thereby make the bulb dimensions of 25W electric arc tube greater than theoretical specification, desired temperature levels in the time of still can satisfying gas discharge, but need not existing equipment is carried out fairly large replacing and debugging, reduced the production difficulty and saved production cost.
The above lamp socket 5 is made of lamp holder 6 that links together and base 7; Base 7 is provided with interface 10, and the outside of base 7 is by metal shell 8a, 8b parcel, and the inside of base 7 also is equipped with starter 9.
Starter is incorporated into lamp socket inside, and starter is shielded isolation, can dwindle the volume of whole auto lamp on the one hand, can avoid starter that the device of periphery is produced electromagnetic interference on the other hand again with metal shell.The installation difficulty and the expense of high-strength gas discharge automobile lamp have been simplified greatly.
When the supporting 20W of the utility model～30W ballast used, the luminous flux of its generation was not more than 2300 lumens, can reduce the generation of dazzle and light pollution effectively, very was suitable as the replacement light source of existing automobile front lamp.Because the size of product is near prior art 35W lamp, reduced the difficulty of producing, be convenient to utilize existing equipment production, simultaneously cost is decreased, and can solve existing high intensity discharge metal halide lamp is assemblied in to be needed attachment device, difficulty is installed on the car load problem, reduced expense, when being installed in it on automobile also than being easier to.
