Description
Technical field
The present invention relates to the explosion-proof lamp in the explosion-proof environment, particularly relate to luminescence component that is used for the flame-proof type explosion-proof lamp and the explosion-proof lamp that relates to flame-proof type.
Background technology
Convert electrical energy into luminous energy and can be called as electric light source with equipment or the utensil that luminous flux is provided.Electric light source is divided into heat radiation light source, glow discharge spot lamp and field by the difference of its principle of luminosity and causes light source.Wherein, incandescent lamp and halogen tungsten lamp are heat radiation light sources, are first generation light sources; Conventional fluorescent lamps, electricity-saving lamp and low-pressure sodium lamp belong to the low-pressure discharge lamp in the glow discharge spot lamp, are second generation light sources; High-pressure mercury lamp, high-pressure sodium lamp and metal halide lamp belong to the high-pressure discharge lamp in the glow discharge spot lamp, are third generation light sources; Light emitting diode (LED) belongs to and to cause discharge lamp, be the 4th generation light source.
The Starting mode of gas-discharge lamp has multiple, comprises hot exposure (as fluorescent lamp), auxiliary electrode starting (as high-pressure sodium lamp), cold high pressure starting (as high-pressure mercury lamp) etc.Gas-discharge lamp has the advantages that the cold conditions impedance is big, starting back impedance sharply diminishes again, and its property class is similar to arc characteristic.Therefore, this class lamp all will manage to produce a pulse high-voltage or adopt starting electrode when starting, make the gas ionization conduction.Because the internal resistance of starting back is too little, the current limiting measures of having to again adopt promptly so-calledly limit electric current with ballast, this just make the wiring of gas-discharge lamp than the incandescent lamp complexity many.Gas-discharge lamp is because its nonlinear internal resistance characteristic, thus in alternating current circuit under the effect of current-limiting inductance and distribution capacity, the high frequency ringing can appear in the two ends of lamp, the operate as normal of serious interference communications equipment and other electronic equipment.Because gas-discharge lamp has adopted current limit by inductance, thereby its power factor is lower, the harmonic content height easily pollutes electrical network.In addition, when the power supply zero crossing, gas-discharge lamp is not luminous, becomes the light-pulse generator of per second 100 times, and this is extremely harmful to eyesight.It should be noted that, at factory floor, if the using gases discharge lamp, when machine rotational speed would reach a certain particular value (corresponding to the integral multiple of light source scintillation frequency), visually just with not rotation is the same for machine, and this illusion is a kind of hidden danger to keeping the safety in production.Because there is above-mentioned shortcoming in glow discharge spot lamp, is necessary to make improvements.
Existed now with filament replace ballast from the ballast mercury lamp, higher to the utilization rate of electric energy.Based on the thermal inertia of its filament, can partly compensate the shake light of wick, but thoroughly not change the character of gas-discharge lamp.
Though fluorescent lamp generally adopts electric ballast recently, has also adopted interference suppression measure, but still adopt the inductance ballast mode, just improved the chattering frequency (about 38kHz) of light source; And if fluorescent tube loose contact or damage, then the high pressure that produces in the ballast very easily makes its electronic component punch through damage.
In addition, gas-discharge lamp is long start-up time, about 2-10 minute.
Electrodeless lamp also belongs to gas-discharge lamp, is made up of radio-frequency generator, coupler and bulb three parts.Electrodeless lamp is coupled in the lamp with induction mode by the radio-frequency generator electromagnetic field, makes the gas avalanche ionization in the bulb, forms plasma.The plasma-excited atom gives off ultraviolet ray when returning ground state.The fluorescent material of bulb inner wall is subjected to ultraviolet ray excited generation visible light.The subject matter of electrodeless lamp comprises:
A. light efficiency problem: the theoretical light efficiency of electrodeless lamp has only 80Lm/W, has only 65Lm/W and the actual product light efficiency has, suitable with electricity-saving lamp, though be better than incandescent lamp, can't compare (sodium vapor lamp/Metal halogen lamp light efficiency 110-120Lm/W) with " sodium vapor lamp/Metal halogen lamp " that be applied to street lamp at present at all.Because it is low that electrodeless light is imitated, with the sodium vapor lamp ratio, for sending same light, the meaning power consumption is more, heating is more serious.If replace the 250W sodium vapor lamp with the electrodeless lamp of 185W, in fact only can be darker.Present electrodeless light is imitated, and does not meet national energy-conservation industrial policy.
B. electromagnetic interference and spacing electromagnetic radiation problem: electrodeless lamp is by " electromagnetic wave or microwave " work, its microwave generator sends the super high power electromagnetic wave, propagation distance can reach thousand kilometers, closely becoming insurmountable " interference source " especially, even the major accident of " electrodeless lamp disturbs the aerial navigation system " is taking place.Point out in Ministry of Construction's " Eleventh Five-Year Plan City Green illuminating engineering planning outline detailed rules for the implementation " that electrodeless florescent lamp is because work in high frequency, thereby the necessary Electromagnetic Interference Test that passes through, otherwise can threaten electrical network and near electrical appliance generation interference.Yet,, thereby also can't effectively solve " electromagnetic interference problem " at present because electrodeless lamp is luminous by super high power " microwave " excitated fluorescent powder.Present electrodeless lamp electromagnetic compatibility technology can't satisfy the requirement of the Ministry of Construction.
In some applied environments, for example in Minepit environment, chemical reaction may take place and the gas or the dust (for example methane gas) that explode in existence, thereby need throw light on by special-purpose explosion-proof lamp.Adopt glow discharge spot lamp explosion-proof lamp (particularly flame-proof type explosion-proof lamp) at present, but, there is following technical problem in it:
1) there is the heavy metal pollution possibility in gas-discharge lamp,
2) gas-discharge lamp needs pulse high-voltage to excite,
3) electromagnetic interference of gas-discharge lamp and spacing electromagnetic radiation height,
4) the stroboscopic problem of gas-discharge lamp is serious,
5) gas-discharge lamp is long start-up time,
6) the gas-discharge lamp light efficiency is low, thereby the power consumption height.
In addition, in the LED light fixture in the market, led light source module and light fixture one are fixed (for example being adhered on the lamp body) and can't be dismantled, and therefore, LED is if any damage, need pull down devastatingly, change, the repair and replacement complexity, even the whole lamp of having to returns factory and office's reason, this process is numerous and diverse, consuming time, causes the waste on the man power and material.
