Automotive headlight is arranged in the front area of motor vehicle and is used for illuminating runway in this motor vehicle the place ahead.As light source, its light is distributed by the light of headlamp with hope gaseous discharge lamp at this, and the formal distribution that for example dipped headlights distributes or high beam distributes is in the front region of headlamp and particularly be distributed on runway.Gaseous discharge lamp has the glass bulb that is filled with gas, is provided with at least two electrodes in this glass bulb.Produce by the gas discharge that ignites the electric arc that sends light between each electrode, by to each electrode continuously supplied with electric power keep this electric arc.Control to the supply of electrical power realizes via the control that is provided for this and/or adjusting device.
The function of the gaseous discharge lamp in headlamp and the luminous flux that particularly produced by this gaseous discharge lamp is subjected to external influence factor, as vehicle power fluctuation, mechanical acceleration and the impacts such as acoustic resonance and aging effect.
In order to compensate these external influence factors, take the measure aspect regulation technology, its purpose is to make the luminous flux of gaseous discharge lamp to keep as far as possible constant.Present being used for of using keeps the measure aspect regulation technology of luminous flux based on determining round lamp power and then this lamp power being adjusted to rated value, because lamp power is measured simply by control appliance consistently.
Yet, the prerequisite of carrying out like this is: gaseous discharge lamp will be fed to it under all ruuning situations the electrical power that is adjusted to steady state value is transformed into luminous power and heat with identical share, thereby the luminous flux that is sent by gaseous discharge lamp is always proportional with constant proportionality coefficient and electrical power.
But, certifiedly be: always complete inconstant in the electrical power of supply and conversion function between the luminous power of determining.Therefore, although lamp power is regulated, the luminous flux of gaseous discharge lamp or the fluctuation of luminous power appear still.
This conversion function for example fluctuation, the machinery of, light temperature aging due to lamp accelerate and each electrode on the electric arc starting point of variation change.
Therefore, for example the glass bulb of gaseous discharge lamp due to salt diffusion and/or electrode erosion and dimmed or even blackening.In addition, cold or cool gaseous discharge lamp has relatively poor efficient, and compares with the gaseous discharge lamp that arrives its operating temperature thus and send less light under identical electrical power.In addition, due to as when travelling in the situation that the machinery that headlamp vibrations or vibration are occurred accelerates, because arc deflection, electric arc extend or cooling when impacting on glass bulb due to electric arc, can cause the luminous efficiency change.
Summary of the invention
Under these backgrounds, task of the present invention is: even in the situation that extraneous interference effect factor exerts an influence, still realize the better constant of luminous flux that the gaseous discharge lamp by automotive headlight sends.
