According to the vanadium arc gas discharge lamp disclosed by the embodiment of the utility model, improvement is made on original tungsten electrodes, a layer of vanadium film is plated on each of the original electrodes, and the luminous efficiency is effectively improved as vanadium has the characteristics of high-temperature resistance and long service life.
Description
Technical field
The utility model relates to the electrical lighting field, particularly relates to a kind of vanadium arc gas discharge lamp.
Background technology
In current daily life, gaseous discharge lamp has become the widely used a kind of illuminations of people.Gaseous discharge lamp is alight by the commingle discharging of gas, metal vapors or several gas and metal vapors.Convert electrical energy into a kind of electric light source of light by gas discharge.Gaseous discharge lamp generally is made of cell-shell, electrode and discharge gas, is vacuum seal between cell-shell and the electrode, is filled with discharge gas in the cell-shell, and the electricity level is placed in the quartz ampoule of sealing, generally adopts tungsten electrode.
In the present gaseous discharge lamp, the applicant is through the research discovery, and the bright brightness that provides is lower, and luminous efficiency is relatively poor.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of vanadium arc gas discharge lamp, and in order to solve the poor problem of gas discharge lamp efficiency in the prior art, specific embodiments is as follows:
A kind of vanadium arc gas discharge lamp comprises cell-shell, discharge gas, quartz ampoule, electrode, wherein is coated with one deck vanadium film at described electrode.
Preferably, described discharge gas comprises gaseous hydrogen, gas xenon.
The disclosed vanadium arc gas of the utility model embodiment discharge lamp, by original tungsten electrode is improved, at the basis of original electrode plating one deck vanadium film because vanadium has characteristic high temperature resistant, long service life, strong raising luminous efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the disclosed a kind of vanadium arc gas discharge lamp of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of vanadium arc gas discharge lamp, in order to solve the poor problem of gas discharge lamp efficiency in the prior art, specific embodiments is as follows:
A kind of vanadium arc gas discharge lamp, its structural representation comprise cell-shell 1, discharge gas, quartz ampoule 2, electrode 3 as shown in Figure 1, and are coated with one deck vanadium film at described electrode 3.In normal use procedure, described vanadium arc gas discharge lamp will be connected with electronic trigger.And described discharge gas comprises gaseous hydrogen, gas xenon.
Described vanadium arc gas discharge lamp, from being triggered to normal luminous need about 1 minute, startup roughly was divided into for three stages:
(1) the triggering stage: by electronic trigger, make vanadium electrode 3 produce high voltage, and make the discharge gas ionization in the lamp, so that electric energy conversion is the kinetic energy of free electron.
(2) ignition phase: after triggering, the discharge voltage of vanadium electrode further heats the vanadium electrode, so that the electronics of rapid movement and gas atom collision, gas atom is excited, and the kinetic energy of free electron is converted into again the interior energy of gas atom, forms glow discharge.
(3) normal glow phase: under the effect of glow discharge, the vanadium alloy electrode temperature is more and more higher, the electron amount of emission is more and more, after the electron amount of vanadium alloy electrode emission reaches certain value, be excited gas atom and return ground state from excitation state, interior can discharging with the form of light radiation with obtaining reaches stable arc discharge state.
High temperature resistant, long service life that vanadium has advantages of.Life period colour temperature stability is good, and the colour temperature consistency between the light source is better, described vanadium arc gas discharge lamp is lighted from point, until life termination, its colour temperature changes within 200K, and general Metal halogen lamp is greater than 600K in the colour temperature variation of life period, so described vanadium arc gas discharge lamp has solved the aberration of quartz metal halide lamp and the drifting problem of colour temperature;
The lumen output meeting of light source was failed along with the time.The disclosed vanadium arc gas of the utility model discharge lamp is because improved luminous efficiency after adopting vanadium alloy to do electrode, lumen at beginning of lifetime is exported just than the high 20-40% of general Metal halogen lamp, the more important thing is that vanadium has durable characteristic, its use makes it can keep the light source output of such level until end-of-life always.This lumen depreciation that just causes the disclosed vanadium arc gas of the utility model discharge lamp is more than 90%, and quartz metal halide lamp then is 60-65%, and its light decay is very fast.
The quality of color rendering properties of light source is also relevant with the tube wall temperature of electric arc tube.In general, tube wall temperature is higher, and its color rendering is also better.Vanadium metal can be high temperature resistant, the electric arc tube tube wall temperature of general Metal halogen lamp can only reach about 800 degree, and the electric arc tube tube wall temperature of the disclosed vanadium arc gas of the utility model embodiment discharge lamp can reach 1500 degree, so its color rendering will be better than general Metal halogen lamp far away.And simultaneously, tube wall temperature is the color temperature difference of influencer's light source also, general Metal halogen lamp is because its largest tube wall temperature can only reach 800 degree, and the height of tube wall temperature is inversely proportional to color temperature difference, so its final color temperature difference also is greater than vanadium arc gas discharge lamp, thus the disclosed vanadium arc gas of the utility model embodiment discharge lamp, owing to having adopted vanadium electrode 3, temperature tolerance is stronger, has lower color temperature difference.
Compare quartz metal halide lamp, the disclosed vanadium arc gas of the utility model discharge lamp also has following advantage: light efficiency improves 10% than quartz metal halide lamp, and color rendering improves 10～20, and the life-span improves greatly, photochromic consistency between lamp and the lamp obviously improves, and the drift of life period colour temperature is little.
The disclosed vanadium arc gas of the utility model embodiment discharge lamp, by original tungsten electrode is improved, at the basis of original electrode plating one deck vanadium film because vanadium has characteristic high temperature resistant, long service life, strong raising luminous efficiency.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
