High property superthin one drag two vehicle xenon lamp stabilizer

Technical field

The utility model relates to the automotive lighting field of components, more specifically says so to relate to a kind of multi-functional, high property superthin one drag two vehicle xenon lamp stabilizer.

Background technology

HID (High Intensity Discharge) high-voltage gas discharging light, also claim xenon lamp, its operation principle is in the quartzy quartz glass tube of (UV-CUT) uvioresistant, fill with inert gases such as xenon (XENON) and iodide, pass through stabilizer (also claiming booster) then, the direct voltage moment of 12V on the automobile is pressurized to about 23000V, concussion excites the xenon electronics in the quartz ampoule to be free in generation jumping arclight between two electrodes through high pressure, colour temperature reaches 4300K, have good illumination and penetration power, and useful life is longer than traditional based on halogen bulb, is just used by increasing automobile; Also there is the cost height in it simultaneously, shortcomings such as wiring disunity, repacking cost height.Claimed structure is compact more in design along with present automobile, the space of the big grade of repacking HID is further reduced, thereby higher requirement is proposed on volume the HID illuminator, present headlight has the shared Lamp cup of far and near light one xenon lamp one Halogen lamp LED of employing simultaneously, one group of xenon lamp of a stabilizer band can't realize that long-and-short distant light all is xenon lamp effects; The mechanical system of employing control xenon lamp luminous element shift position in Lamp cup is arranged, and by extension electromagnetic adhesive principle, all is xenon lamp thereby reach far and near lamp, but there is the failure rate height in this method, instability, defective such as mechanical endurance is short, switching times about 5000 times; And adopt two Xe lamp bulb one is one group, and one group etc. with two stabilizers, the performance height, and the life-span is long, and is effective, but cost is too high.As application number is 02230344, the applying date is on April 1st, 2002, denomination of invention is the patent application of the circuit of automotive HID (high brightness) lamp special use, comprise a lamp diverter switch, it is a single-pole double-throw switch (SPDT), provide the switching of far away, nearly HID lamp to use, two lines that power supply is imported are transformed into three output lines, i.e. common wire COM, lamp connecting line H, low beam control line L far away; It is characterized in that: be provided with the far and near lamp switching delay circuit of a H/L and HID lamp group current supply circuit two parts; The far and near lamp switching delay of this H/L circuit is to have a lamp diverter switch, is a single-pole double-throw switch (SPDT), provides the switching of far away, nearly HID lamp to use, and two lines that power supply is imported are transformed into three output lines, i.e. common wire COM, lamp connecting line H, low beam control line L far away; One polarity corrective loop is made of six diode D1-D6 and two resistor R 1, R2 of being serially connected with above-mentioned three output lines side by side, and it arranges the arrangement with rectified three-phase circuit; Above-mentioned three output lines are transformed into two output lines with definite positive and negative polarity are connected to the time delay loop, guarantee that circuit can not produce in wrong start; One time delay loop, be that its output connects isolated loop by a capacitor C1 and resistor R 3, charge-discharge circuit that R4 constituted, capacitor C1 stores for future use as electric current, simultaneously via the stable supply of current of resistor R 3, R4 to isolated loop, the transient fluctuation when avoiding switch S to switch; One isolated loop is to be provided with an optical coupler PH, comprises signal transmitting terminal PH1, and the two ends output of above-mentioned resistor R 4 is connected to the input of this optical coupler PH, and promptly signal transmitting terminal PH1 uses that the photoinduction of switch current signal mat is reached HID lamp group current supply circuit; HID lamp level current supply circuit then has an isolated loop, signal receiving terminal PH2 with above-mentioned optical coupler PH, it is the output of optical coupler PH, base stage and the collector electrode of this output termination transistor TR1, to receive photoinduction signal by the PH1 emission, form coupling, the break-make of control transistor TR1 is as the usefulness of photosensitive switch; The coil tandem of the emitter and collector of transistor TR1 and relay R E is used and can drive the big current circuit action of conducting when being received signal in both ends of power; The big current circuit of one conducting is to have a relay R E, and the contact S1 of this relay R E and S2 are serially connected with between storage battery group and the electric stabilizer BAL, its role is to control the start of electric stabilizer BAL and low beam L; One storage battery group, original power supply is as far away, the required electric power of low beam are provided on the car; One HID lamp group loop is for starting headstock left and right each one group of electric stabilizer and HID lamp.This patent adopts single-pole double-throw switch (SPDT) to switch far and near light exactly, and still each needs one group of stabilizer about its headstock, and its complex structure, the cost height, and volume is big.
