Description
Technical field
The utility model relates to the inflation on-line measuring device of electrodeless lamp luminous element.
Background technology
To the mercury ion in the luminous element, described luminous element also is bulb or fluorescent tube to electrodeless lamp application electromagnetic induction principle, and produces ultraviolet ray with electromagnetic energy transfer, and bulb or the inner surface of tube are coated with phosphor powder layer, and its ultraviolet radiation-absorbing sends visible light.Its process is that radio-frequency generator passes through the high-frequency electrical feeder line and powers to high frequency coil, produce the electromagnetic field of high frequency, mercury ion produces ultraviolet, visible spectrum beta radiation after by the high-frequency electromagnetic field excitation, its ultraviolet, visible light spectral line comprise ultraviolet 185nm, 253.7nm, 365nm, and visible light 404.6nm, 435.8nm, 546.1nm, 577nm, 579nm wavelength or the like, the fluorescent coating of the ultraviolet ray excited glass bulb inner surface of 253.7nm and 365nm wherein, ultraviolet ray are sent visible light after being absorbed by fluorescent material.Mercury vapor pressure in the bulb is provided by amalgam.
Based on this principle, bulb or fluorescent tube do not need filament, and therefore, the useful life of electrodeless lamp is very long, can reach 6-10 ten thousand hours, and luminous efficiency reaches 80 lumens/watt, are a kind of high light efficiency, long-life novel energy-conserving light source.
Electrodeless lamp divides built-in and external, and the luminous element of built-in electrodeless lamp often is a bulb, and described bulb has the cavity that high frequency coil is set, and the luminous element of the electrodeless lamp of external mostly is fluorescent tube, and described high frequency coil is outside fluorescent tube.
Make high-quality electrodeless lamp bulb, fluorescent tube, need weigh with two major technology indexs:
A, high luminous efficiency, lumens/watt (lm/W),
B, stable light beam colour temperature.
According to low-pressure mercury vapor electric discharge principle, 253.7nm ultra-violet radiation efficient maximum when mercury vapor pressure is 0.8 Pa can obtain the high-luminous-efficiency and the stable light beam colour temperature of light source.When mercury vapor pressure departed from 0.8 Pa, the 253.7nm radiation efficiency reduced, and other radiation spectral lines increase, and the light beam colour temperature changes.Because the working temperature of electrodeless lamp is higher, and the requirement of taking environmental conservation into consideration, generally use amalgam and set up mercury vapor pressure, for obtaining 0.8 Pa mercury vapor pressure condition, need to determine only high temperature amalgam model, reach high light efficiency and stable light beam colour temperature.
In addition, also to charge into some inert gases in the luminous element, be called buffer gas, as argon gas, krypton gas.It can increase the collision opportunity between mercury ion, reduces the collision loss on the luminous element inwall, improves radiation efficiency.But inert gas can not charge into too much, otherwise also can cause the energy loss that causes with the interionic collision.Luminous element for different capacity and volume need charge into best inert gas atmospheric pressure value, could obtain the highest luminous efficiency.
At present, the working procedure on the electrodeless lamp production line is as follows:
A, oneself be coated with fluorescent material electrodeless bulb, place that exhaust vacuumizes under the heat cover, remove heating mantles then; Charge into inert gas, whether the air pressure that charges into inert gas with the spark coil leak detector estimation is suitable;
B, with reference to Fig. 1, Fig. 1 is 4 operations that charge into inert gas, cut off bulb: operation 1, from vacuumize the filling of station, exhaust station is cut off bulb; Operation 2 and 3, bulb moved to annotate the amalgam station, fall turnback, inject amalgam m to correct position; 4, the grass tube on the bulb is cut off and sealed.
C, the electrodeless bulb that completes, form an electrodeless lamp of lighting only with radio-frequency generator 1 and high frequency coil 3.
In sum, on the present electrodeless lamp production line, the inert gas air pressure size of bulb (fluorescent tube), only be to estimate with spark coil leak detector, lighting bulb (fluorescent tube) must it fill again, cut off on the exhaust station and could realize, the best air pressure of the required inert gas of the electrodeless lamp of every kind of power is different, need test of many times to determine, adopt traditional operation and equipment, will be repeatedly through tens of inferior inflations, cut off operation, could determine best inert gas inner gas pressure, therefore high-quality electrodeless bulb (fluorescent tube) that can not the best photochromic technical parameter of very fast acquisition, and because the trouble of test operation, the photochromic technical parameter of its acquisition often is not best parameter.
