Colour temperature is the most general index of expression light source light spectrum quality, is determined by the distribution of light source relative spectral power.When colour temperature requires to be lower than 3200K, generally use halogen tungsten lamp, when colour temperature is higher than 4300K, generally use xenon lamp.Existing halogen tungsten lamp is to use the mode of regulating operating voltage or operating current to regulate continuously colour temperature.Xenon lamp is a kind of high-pressure discharge light source of high colour temperature; Its operation principle is in quartz glass tube; With inert gas fillings such as xenon and iodide; And then see through booster DC voltage moment of 12 volts is pressurized to 23000 volts electric current, excite the xenon electronics in the quartz ampoule free through the high pressure amplitude of vibration, between two electrodes, produce light source.Existing mode of regulating operating voltage or the next adjusting continuously of operating current colour temperature can't be used for the continuous adjusting of high colour temperature.
In the existing market, regulate the xenon lamp colour temperature and adopt specific colour filter to realize, promptly before xenon lamp, insert the colour temperature of the fixing colour filter of an optical characteristics needing to obtain.The limitation of doing like this is to obtain the light source of continuous high colour temperature, can not satisfy the demand of the image planes uniformity test of various photo electric imaging systems.In addition; Colour temperature itself is a characteristic attribute of light source, in different fields, and different industries; Requirement to colour temperature is different; The realization of continuously adjustable color temperature light sources can adapt to the needs of different-colour, has good versatility, and therefore the continuous adjustable of high colour temperature will have very wide application prospect.
Summary of the invention
To the problem that prior art exists, one of the object of the invention is to provide a kind of simple high colour temperature easy to adjust continuously adjustable uniform source of light device, can produce the uniformly light-emitting lambertian of specific high colour temperature.Another object of the present invention is to provide a kind of high colour temperature continuously adjustable method.
For realizing above-mentioned purpose; The continuously adjustable uniform source of light device of high colour temperature of the present invention; Comprise high-pressure discharge light source, beam condensing unit, gradual filter, apparatus for adjusting position and integrating sphere, the light that said high-pressure discharge light source sends is radiated at after said beam condensing unit focuses on the said gradual filter that thickness gradually changes along a direction; Said gradual filter apparatus for adjusting position is used to regulate gradual filter and moves gradually along said direction; Light through gradual filter is injected said integrating sphere, and forms moving and the even lambertian of the high colour temperature of continually varying with gradual filter at integrating sphere light-emitting window place.
Further, said high-pressure discharge light source is xenon source, high-pressure sodium lamp or high-pressure mercury lamp.
Further, said beam condensing unit is a slice condenser or the set of lenses that is used for optically focused.
