Description
Technical field
The present invention relates to a kind of gas-discharge lamp that is particularly useful for automotive headlight, it has the discharge tube (Brenner) of tube with electronic ballast, and ballast is configured in plastic casing.
Background technology
Nowadays many motor vehicles have xenon gas-discharge lamp in headlamp.Development course starts through too much extend to the D4 lamp of current use for lamp from D1 lamp thus.Xenon gas-discharge lamp utilizes controller operation, the high-voltage pulse that controller is provided for lighting and for the alternating voltage of the operation of gas-discharge lamp.With regard to current D4 lamp, the discharge tube of cartridge socket is placed in headlamp and by incoming line and is connected with the controller, the electric ballast (EVG) that are arranged in outside reflector.Electric ballast has to be lighted unit and is next devoted to optical efficiency and controls for what discharge tube was lighted.
For this xenon gas-discharge lamp for automotive headlight of latest generation that is described D5 lamp, discharge tube should be directly installed on electric ballast.Then the whole unit consisting of discharge tube and ballast is loaded into reflector.The ballast of this lamp is built in plastic casing, plastic casing be placed into around metal shell in.Discharge tube is fastened on metal shell and by the sleeve pipe on metal and plastic casing and is electrically connected to the parts of electric ballast.
Problem is resistance to vibration and the resistance to impact of this gas-discharge lamp thus, and it must meet higher requirement owing to using in motor vehicle.
Summary of the invention
The object of the invention is to, provide a kind of gas-discharge lamp of the above-mentioned type, it is with the electric ballast of inserting in metal shell, and this gas-discharge lamp meets the high request to resistance to vibration and resistance to impact for motor vehicle.
This technical problem is with solving by gas-discharge lamp claimed in claim 1.The favourable design of this gas-discharge lamp is that the interior of dependent claims perhaps can draw from ensuing description and embodiment.
The gas-discharge lamp that is particularly useful for automotive headlight of advising comprises the discharge tube with electric ballast, electric ballast is configured in plastic casing, and comprise metal shell, plastic casing be arranged in metal shell and fastened this metal shell of discharge tube on.Discharge tube at this by extending into the sleeve pipe of plastic casing from metal shell and the parts of electric ballast are electrically connected to.Gas-discharge lamp is characterised in that, metal shell is mechanically connected with plastic casing by least one screw connection in the region of sleeve pipe.
The inventor of the gas-discharge lamp of advising recognizes at this, and the sleeve pipe of the electronic unit from discharge tube to ballast plays an important role to desired resistance to vibration and resistance to impact.May be due to the vibration between plastic casing and metal shell impaired and thereby cause the rapid failure of lamp in the electrical connection between discharge tube and ballast.By metal shell and plastic casing fixing via screw connection in the region of this sleeve pipe, the service life that can avoid this defect and obviously improve lamp under general service condition.Screw connection must be arranged to such an extent that enough approach sleeve pipe at this, to prevent the contrary motion on this position of metal shell and plastic casing.Screw connection preferably has with sleeve pipe the spacing that is less than 1 cm at this.Particularly advantageously, at least two screw connections that separate are installed on the circumference of sleeve pipe.
Each screw connection is formed by screw element, and screw element is preferably screwed in the tapped blind hole being configured on plastic casing.Tapped blind hole is preferably configured as tapping screw thread at this, thereby just produces screw thread by being screwed into screw element.Tapped blind hole preferably on top also has suitable chamfered section on edge, to simplify arrangement and the screw-in of screw element in industrialization manufacturing engineering.
In a kind of expansion design of advised gas-discharge lamp, utilize one of screw connection that earth connection is fixed on metal shell and thereby reached the ground connection of the safety of metal shell.Earth connection preferably has shackle at this on its end, and when manufacturing screw connection, screw element is guided through this shackle.Therefore in this design that is threaded jockey, not only reduce vibration to the adverse effect being electrically connected to discharge tube, also set up the necessary ground connection of metal shell simultaneously.
Discharge tube is preferably placed on base circle, and base circle is fixed on metal shell and surrounds the sleeve pipe of metal shell.At least one screw connection in this preferred arrangements in the inside of the face of being received by base circle and/or surrounding of metal shell or directly and this face adjacency.
Gas-discharge lamp is preferably equipped with xenon gaseous discharge pipe and is therefore a kind of expansion design of the D4 lamp for automotive headlight up to now.The gas-discharge lamp of advising can certainly be applied for other.

The specific embodiment
Next describe an example by xenon gas-discharge lamp of the present invention in detail.Fig. 1 shows this gas-discharge lamp for this reason, and with xenon gaseous discharge pipe 1, it utilizes base circle 2 to be arranged on metal shell 3, and electric ballast is placed in metal shell.This gas-discharge lamp can again see in Fig. 2 in top view, and top view shows the plate with the top of the metal shell 3 of base circle 2.In base circle 2 inside, can see sleeve pipe 4, the high-pressure metal line 5 that the electric component of discharge tube 1 and ballast is coupled together extends in the central authorities of this sleeve pipe.At this, in the region of sleeve pipe 4, be screwed into two screw elements 6, only can have seen that in the drawings the plastic casing in metal shell of inserting by two screw connections and electric ballast couples together in other words and metal and plastic casing to be threaded connection to device on these positions, to interfix by metal shell 3 in them one and they.
Fig. 3 shows the section along B-B of Fig. 2.In this section, can see the dorsal part 7 of plastic casing, the plate on the top of metal shell 3 and base circle 2 thereon of suit together with discharge tube 1.Can see in this drawing two screw elements 6 of the screw connection between metal shell 3 and plastic casing.Screw element 6 is screwed in the tapped blind hole 13 of plastic casing.
Fig. 4 shows the intercepting part of the top view of plastic casing 9, wherein can see two screw elements 6 of sleeve pipe 4 in plastic casing 9, screw connection and run through the high-pressure metal line 5 of guiding.In addition, can also see the earth connection 8 of the staple for strap of drawing from ballast in this example, one of them screw element 6 guiding is by this shackle.Make thus earth connection 8 be threaded connection device and be fixed on metal shell 3, thereby make metal shell pass through this earth connection 8 ground connection.
Fig. 5 finally also shows the top view of the inside of plastic casing 9, can see one of them position of the part of earth connection 8 and two screw connections in top view.
Fig. 6 shows the perspective view of the inside of plastic casing 9.Can that is to say from rear in the drawings from seeing opened plastic casing 9 with opposed that side of discharge tube.A part that only shows in this drawing ballast is arranged in especially electric wire 10 of electronic unit in this plastic casing, comprises earth connection 8,12V plug 11 and transformer chamber 12.Fig. 7 has illustrated the top view of seeing from front side of plastic casing 9 in intercepting portion, can see the end of sleeve pipe 4, tapped blind hole 13 and earth connection 8 in this top view.
Tapped blind hole 13 has tapping screw thread and constructs integratedly with the plastic casing 9 of electric ballast.Fig. 8 shows the cross-sectional view of an example of tapped blind hole 13, wherein, on top on edge, can see for introducing better the chamfered section 14 of screw element.This figure also illustrates an exemplary size of tapped blind hole 13.
