Description
Technical field
The present invention relates to car light field, in particular to the xenon lamp of green light.
Background technology
Xenon lamp (HighintensityDischarge) refers to the mixture of the internal noble gas being full of and including xenon, there is no the high-voltage gas discharging light of the filament that Halogen light (halogenlamp) has, it is called for short HID xenon lamp, its principle of luminosity is by trigger and electric ballast, voltage is increased to more than 23000V and shocks by electricity xenon thus causing that xenon forms electric arc and luminous between two electrodes. Owing to xenon lamp is a branch of arclight adopting high-tension current to activate xenon and being formed, can continuous discharge luminescence between electrodes. The power of general-utility car bulb reaches 55 watts, and xenon lamp only needs 35 watts, reduces nearly half, and therefore xenon lamp can substantially alleviate the burden of vehicle electrical system, is widely used to car lighting lamp. The colour temperature of automobile xenon lamp, between 4000K 6000K, is significantly larger than common in-vehicle headlight bulb. Its brightness is high, the xenon lamp of 4300K photochromic partially yellow for white, and owing to colour temperature is relatively low, visual effect is partially yellow.
Along with people are to the diversified demand of car light light, xenon lamp development person develops the xenon lamp of blue light-emitting, purple light gradually, and xenon lamp has blue light, the light colour developing of xenon lamp, and relevant with its colour temperature, different colour temperature colors is different, 3000K sodium yellow; 4300K middle band in vain is yellow; 5000K light is entirely white; 6000K light is entirely white, bit bluish; Daytime under 6500K sunlight; During 7000-8000K is white, substantially band is blue. Simply white light, gold-tinted are all relatively common, and blue light, purple light easily cause visual fatigue.
Such as, CN1460281 proposes a kind of high-voltage gas discharging light, it includes a bulb with at least two cervical region and a vacuum-tight discharge vessel being made up of quartz glass, two electrodes stretched in this discharge vessel, and is in filler in the discharge vessel of discharge condition under duty. Discharge vessel closes a width lower than 4 millimeters, and the discharge space that length is lower than 8 millimeters, filler includes NaI, ScI3、Xe、ZnI2. When for automobile headlamp, in order to form required light beam on street, it is desirable to light source must become point-like as far as possible, namely produces luminous intensity high as far as possible in zonule such that it is able to projected more accurately on street by arc of lighting. The light of headlight is illuminated and has improved by this patent, does not but account for change car light glow color mentioned above, caters to people's problem to car light color diversified demand.

Accompanying drawing explanation
Fig. 1 is the structural representation of the xenon lamp of green light in the embodiment of the present invention 1;
Fig. 2 is the coordinate range during xenon lamp luminescence of green light in Fig. 1 of the present invention.
Detailed description of the invention
The present invention is described in further detail in conjunction with accompanying drawing below by specific embodiment.
Considering that the white light that current automobile xenon lamp sends is relatively common, the blue light that sends, purple light easily cause the visual fatigue of people, and the present invention proposes the xenon lamp of a kind of green light, it is possible to send the green glow of people's vision of releiving.
The xenon lamp of this green light, including: airtight discharging chamber, two electrodes, two molybdenum sheets and two molybdenum filaments, the left and right sides of discharging chamber is with shrinking cervical region, two electrodes lay respectively at the both sides of discharging chamber, the cervical region that shrinks being each passed through correspondence extends to the inside of discharging chamber, two electrodes are in the other end outside discharging chamber and are sequentially connected in series molybdenum sheet, molybdenum filament respectively, and halogenation thallium, hydrargyrum and xenon are filled in the inside of discharging chamber.
The xenon lamp of this green light is energized, by molybdenum filament one end is applied high-voltage pulse, moment punctures the discharging chamber between two electrodes, make the noble gas xenon within discharging chamber puncture and luminous, volatilize with mercuric chloride in temperature and participate in electric discharge, after constant temperature rises to thallium volatilization, electric discharge enters the stabilization sub stage, form stable discharging electric arc, the light superposition that several elements send, form green glow.
It follows that the xenon lamp of this green light is described in detail:
A kind of xenon lamp of green light, as shown in Figure 1, including: airtight discharging chamber, the relative of discharging chamber has contraction cervical region every adjacent band, the cervical region that shrinks of two electrode traverse correspondence positions extends to the inside of discharging chamber, two electrodes are in the other end outside discharging chamber and are sequentially connected in series molybdenum sheet, molybdenum filament, and halogenation thallium, hydrargyrum and xenon are filled in the inside of discharging chamber. Molybdenum sheet plays the effect of transition, sealing-in and conduction in gas-discharge lamp. During due to discharging chamber luminescence, hydrargyrum produces ultraviolet, therefore, carries out ultraviolet filtering by outer jacket pipe, and protects internal discharge cavity.
In order to make electrode, molybdenum sheet, molybdenum filament be fixedly connected, in discharging chamber the same side, weld between molybdenum filament and molybdenum sheet, weld between molybdenum sheet and electrode.
Press seal is carried out to molybdenum sheet and molybdenum filament weld (including molybdenum sheet and molybdenum filament weld), to seal off discharging chamber shrinking cervical region.
Halogenation thallium includes: thallium iodide or thallium bromide. Wherein, when halogenation thallium adopts thallium iodide and thallium bromide, Fig. 2 is chromaticity coordinates scope. Specifically can produce x coordinate 0.27-0.3, the green light of y-coordinate 0.44-0.46.
In halogenation thallium, the weight of element thallium is 0.04-0.2 milligram, and the weight of hydrargyrum is 0.8-1.5 milligram, and the pressure of xenon is 6-8 atmospheric pressure. When using the halide discharge of thallium, its mercury quantity added is than conventional colour temperature, as 4300K wants many (about about 0.8mg of 4300K mercury quantity, and green thallium luminescence needs about 1.2mg) it is mainly the discharge channel that thallium steam is formed, voltage difference is relatively low, electromotive force can not meet ballast normal operation, it is therefore desirable to by the increase of mercury quantity, promotes steam pressure and interelectrode electric potential difference. The electric potential difference making lamp two ends reaches 85V ± 17V. Additionally the increase of thallium amount will cause that color is turned white, and the minimizing of thallium amount will make lamp occur, and easily blackout equivalent life shortens phenomenon. Therefore this product has a best weight and corresponding mercury quantity requirement
In order to produce required green glow, the size Control of discharging chamber, through exploring, is existed: in discharging chamber by inventor, and the beeline of two electrodes is 3.75-4.65 millimeter. Discharging chamber is elliposoidal, and the relative cervical region line that shrinks crosses the prolate face of elliposoidal, and the inner length of discharging chamber is 6.5-7.5 millimeter, and internal height is 2.6-3.2 millimeter.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations. All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
