The xenon lamp assembly further comprises a transformer which consisting of a high voltage starter and a ballast. The lamp holder is arranged on the transformer. The xenon lamp assembly has the advantages that the electric wire connection between a traditional transformer and the lamp holder is eliminated, so that high voltage produced through the high voltage starter can be directly conducted to a lighting tube of the xenon lamp so as to light the lamp, cause less pulse energy loss, produce less interference on the outside and greatly improve the reliability of the transformer; the transformer and the lamp holder are integrally clamped in a mounting opening of a headlight of a vehicle, so that the transformer needs no space in the headlight when in installation, thereby simplifying the installation procedures.

Description

A kind of xenon lamp assembly

Technical field

The utility model relates to a kind of car headlamp assembly, especially relates to the xenon lamp assembly.

Background technology

Common xenon lamp assembly comprises the be fixed as one lamp holder, lamp socket and the xenon lamp that are provided with and the transformer of being made up of the stabilizer that is used to start the high-voltage starter of xenon lamp and keep xenon lamp to continue to light, xenon lamp is belong to high-intensity gas discharge lamp a kind of, and it starts the starting impulse point modulating voltage that needs tens thousand of volts.And this kind high-voltage starter of being used for starting impulse point modulating voltage is mounted in the stabilizer usually, and its advantage is that the electric current of high-voltage starter is directly taken from stabilizer, and the connection line of starter and stabilizer is shorter, very compactness; Its weak point is, distance between high-voltage starter and the lamp has been elongated, high-voltage starter is more by lead-in wire distribution capacity and inductive bleedover, the high pressure amplitude is reduced, the pulsewidth aggravation has influenced and has lit a lamp, and its leakage signal also can be disturbed electronic devices and components generation on every side, serious meeting is coupled in the circuit of stabilizer and is caused interference, influences stabilizer and runs well.

Another kind of existing xenon lamp assembly is with high-voltage starter and stabilizer split, high-voltage starter is arranged in the xenon lamp lamp socket, and stabilizer is electrically connected with high-voltage starter by lead, can make the high voltage startup triggering signal drop to minimum like this to the influence of stabilizer, but the distance between high-voltage starter and the stabilizer has widened, stabilizer produces certain retardance, the reliability that influence is lit a lamp for the signal that high-voltage starter provides.

Above-mentioned two kinds of xenon lamp assemblies have a common problem, and promptly stabilizer all is to be connected with xenon lamp by one section long lead.As everyone knows, because the other inside roominess of the headlamp light fixture of the car of different model is narrow, the installation of promising transformer does not provide abundant space, therefore after selecting suitable position, need to use double faced adhesive tape, band, screw that transformer is fixed in the car body, fixed form is cumbersome, and the existence that connects electric wire simultaneously produces certain electromagnetic interference to electronic circuit again.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, easy installation and reliable and can reduce the xenon lamp assembly of electromagnetic interference greatly.

For realizing above purpose, the utility model has been taked following technical scheme: a kind of xenon lamp assembly, comprise interconnective xenon lamp, lamp holder and lamp socket, and also include transformer, this transformer includes high-voltage starter and stabilizer, and described lamp socket is arranged on the described transformer.

The installing port place that transformer and lamp socket are fixed as one and are connected and are connected in the car headlamp light fixture, not only overcome between traditional transformer and the lamp socket drawback that must be connected by connecting line, and need not in light fixture to seek the space for the position of stationary transformer, make easier for installation.

Described high-voltage starter is arranged in the described lamp socket, and described lamp socket is arranged on the described stabilizer.High-voltage starter is arranged in the lamp socket, not only make the high voltage pulse of its generation can directly connect xenon lamp, lamp is lighted, the energy loss of pulse is few, and isolate with the electronic devices and components on the ballast circuit plate, reduced the electromagnetic interference of high-voltage starter, the ballast reliability is greatly improved, improved the security reliability that system starts stabilizer.

Described lamp socket is a groove structure, and its opening is towards described stabilizer, and this groove comprises at least two storage tanks, and one of them storage tank is provided with high-voltage starter, is provided with the start-up circuit that cooperates described high-voltage starter in another storage tank.To keep apart by trough rim as the magnetic core and the start-up circuit of high-voltage starter, make between magnetic core and the start-up circuit unaffected mutually, effectively guarantee high-voltage starter to the high-voltage pulse of xenon lamp start timely and stable, improve the startability of lamp.

The sidewall of described lamp socket has turned down flanging outwardly, and described stabilizer has the link that cooperates with this flanging, flexibly connects by flanging, link between described lamp socket and the described stabilizer.The structure of flanging makes things convenient for lamp socket and stabilizer to flexibly connect, and is for convenience detach, helps the repacking and the maintenance of car headlamp.

Described lamp socket is provided with metal shielding outward.Metal shielding is limited in the high-tension electricity magnetic field impulse influence to external world of high-voltage starter in the shielding case, and interference to external world is minimum, further reduces the electromagnetic interference when starting.

Also be connected with combination hub on the described lamp socket, include connecting line, the one end is electrically connected with this combination hub, is connected with standard socket on this connecting line other end, and this standard socket is electrically connected with vehicle light power supply.With stabilizer with after lamp socket is fixedlyed connected, the lead-out wire of the electronic devices and components such as high-voltage starter in the lead-out wire of xenon lamp electrode, the lamp socket, all can be between the inside that stabilizer and lamp socket join cabling, finally be connected in the combination hub on the lamp socket, and the electric power connection line of a standard promptly can be transformer-supplied, numerous and diverse electric wire of having simplified greatly in the headlamp light fixture is impeded, and has reduced electric wire itself to the electromagnetic interference of electronic devices and components on every side.

The utility model compared with prior art, has following advantage: transformer is fixedlyed connected with lamp socket, saved impeding that electric wire is connected between traditional transformer and the lamp socket, the high pressure that high-voltage starter is produced directly is switched to fluorescent tube, lamp is lighted, pulse energy is lost seldom, and less to external world generation interference, and the transformer reliability is greatly improved; Transformer and lamp socket one are connected in the installing port place of car headlamp light fixture on the other hand, make to need not when installing to seek enough spaces for transformer in light fixture, have simplified installation procedure.
