Description
Technical field
The present invention relates to car light field, in particular to the xenon lamp of green light.
Background technology
Xenon lamp (High intensity Discharge) refers to the internal inert gas full of including xenon
Mixture, without the high-voltage gas discharging light of filament possessed by Halogen lamp LED (halogen lamp), abbreviation HID xenon lamp, its
Principle of luminosity is by starter and electric ballast, and voltage is improved to more than 23000V and shocks by electricity xenon so as to cause xenon to exist
Electric arc is formed between two electrodes and is lighted.Because xenon lamp is using high-tension current activation xenon and a branch of electric arc for being formed
Light, continuous discharge it can light between electrodes.The power of general-utility car bulb reaches 55 watts, and xenon lamp only needs 35 watts, reduces
Nearly half, therefore xenon lamp can substantially mitigate the burden of vehicle electrical system, be widely used to car lighting lamp.Vehicle xenon
The colour temperature of lamp is between 4000K -6000K, significantly larger than common in-vehicle headlight bulb.Its brightness is high, the light of 4300K xenon lamp
Color is partially yellow for white, and because colour temperature is relatively low, visual effect is partially yellow.
As people gradually develop the xenon of blue light-emitting, purple light to the diversified demand of car light light, xenon lamp development person
Gas lamp, xenon lamp have blue light, and the light colour developing of xenon lamp, relevant with its colour temperature, different colour temperature colors is different, 3000K
Sodium yellow；Band is yellow during 4300K is white；5000K light is entirely white；6000K light is entirely white, bit bluish；Daytime under 6500K sunlight；7000-

Brief description of the drawings
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 when xenon lamp of green light in Fig. 1 of the present invention is luminous.
Embodiment
The present invention is described in further detail below by specific embodiment combination accompanying drawing.
The white light sent in view of current automobile xenon lamp is relatively common, and blue light, the purple light sent easily causes people's
Visual fatigue, the present invention propose a kind of xenon lamp of green light, can send the green glow for people's vision of releiving.
The xenon lamp of the green light, including：Closed discharging chamber, two electrodes, two molybdenum sheets and two molybdenum filaments, electric discharge
The left and right sides of cavity is located at the both sides of discharging chamber, is each passed through corresponding contraction respectively with neck, two electrodes are shunk
Neck extends to the inside of discharging chamber, and the other end that two electrodes are in outside discharging chamber is sequentially connected in series molybdenum sheet, molybdenum respectively
Silk, inside filling halogenation thallium, mercury and the xenon of discharging chamber.
The xenon lamp of the green light is powered, by applying high-voltage pulse to molybdenum filament one end, moment puncture two electrodes it
Between discharging chamber, the inert gas xenon inside discharging chamber is punctured and is lighted, volatilize and participate in mercuric chloride in temperature
Electric discharge, after constant temperature rises to thallium volatilization, electric discharge enters the stabilization sub stage, forms stable discharging electric arc, and several elements are sent
Light superposition, formed green glow.
Next, the xenon lamp of the green light is described in detail：
A kind of xenon lamp of green light, as shown in figure 1, including：Closed discharging chamber, the relative adjacent compartment band of discharging chamber
There is contraction neck, the contraction neck of two electrodes through correspondence position extends to the inside of discharging chamber, and two electrodes, which are in, to be put
The other end of electric containment portion is sequentially connected in series molybdenum sheet, molybdenum filament, inside filling halogenation thallium, mercury and the xenon of discharging chamber.Molybdenum sheet exists
Play a part of transition, sealing-in and conduction in gas-discharge lamp.Mercury produces ultraviolet when being lighted due to discharging chamber, therefore,
Ultraviolet filtering is carried out by outer jacket pipe, and protects internal discharge cavity.
In order that electrode, molybdenum sheet, molybdenum filament are fixedly connected, in discharging chamber the same side, welded between molybdenum filament and molybdenum sheet,
Welded between molybdenum sheet and electrode.
Press seal is carried out shrinking neck to molybdenum sheet and molybdenum filament weld (including molybdenum sheet and molybdenum filament weld), with seal isolation
Discharging chamber.
Halogenation thallium includes：Thallium iodide or thallium bromide.Wherein, when halogenation thallium uses thallium iodide and thallium bromide, Fig. 2 is chromaticity coordinates
Scope.X coordinate 0.27-0.3, y-coordinate 0.44-0.46 green light can specifically be produced.
The weight of element thallium is 0.04-0.2 milligrams in halogenation thallium, and the weight of mercury is 0.8-1.5 milligrams, and the pressure of xenon is
6-8 atmospheric pressure.Using thallium halide discharge when, its mercury quantity added is than conventional colour temperature, and such as 4300K wants more (4300K mercury
Measure about 0.8mg or so, and green thallium is luminous needs 1.2mg or so) be mainly the discharge channel that thallium steam is formed, voltage difference compared with
Low, potential can not meet ballast normal work, it is therefore desirable to by the increase of mercury quantity, lift steam pressure and interelectrode electricity
Potential difference.The electrical potential difference at lamp both ends is set to reach 85V ± 17V.The increase of other thallium amount will cause color to be turned white, and the reduction of thallium amount will
Lamp easy nigrescence equivalent life is occurred and shorten phenomenon.Therefore the product has an optimal weight, and corresponding mercury quantity requirement
