Description
Technical field
The present invention relates to a kind of total space distributed luminosity tester of fixed light source formula, carry out near field total space precision measurement for the luminous flux to the various light sources such as the various model Vehicular lamp of fixed installation position and the Projecting Lamp that needs fixed angle to install and light fixture, light distribution and photochromic distribution.
Background technology
The measurement of distributed luminosity, generally realizes luminous flux, the luminous intensity distribution measurement of light source or light fixture with illumination photometry, with the photochromic distribution of spectrometer measurement.During measurement, by measuring the Illumination Distribution of the simulation sphere centered by measured light, the total light flux of measured light is calculated by numerical integration, calculate the light intensity of often by illumination inverse square law and then draw the space distribution of light intensity, go out often photochromic by spectrometer measurement and then draw photochromic space distribution, the method of above-mentioned three kinds of measuring method Dou Shi International Commission on Illumination (CIE) recommendations, luminous flux measurement method is again reference measurement method.
The present situation of prior art is: except the center of measured light cannot accurately be determined, depart from photo-detector and test result is affected quite greatly, test of light source change in location or motion also can affect the result of measurement, this be due to: 1, after measured light change in location, radiating condition there occurs change, emergent light direction also there occurs change, thus affects test result; 2, measured light produces air-flow because of motion, causes measured light surface, heat dispersion heat sink temperature changes, thus affect test result; 3, gas-discharge lamp electric discharge arc of lighting change in location or move, the geospace magnetic line of force can affect the arc-distribution in lamp, and then affects the job stability of lamp; 4, the vibration that measured light produces because of circular motion can affect the steady operation of light source.Therefore, test photo detector can not accurately aim at measured light center, and measured light can not keep transfixion under actual working state, if keep measured light motionless, cannot complete again the test of global space of planes, method lacks scientific, so test error is larger.
Existing distribution photometer, mainly contains two kinds:
One is light source displacement type total space distribution photometer, it is the position by rotating light source to be measured, and the detection realizing luminous flux, photochromic and light intensity is rotated by photo-detector, during detection, measured light needs vertically to irradiate over the ground, the measured light of other shooting angle can not be tested, and ground has reflection in the face of light, therefore can not ensure measuring accuracy;
Another kind is fixed light source formula non-fully space distribution photometer, and it makes vertical rotation by the U-shaped pivoted arm on pedestal, and the photo-detector simultaneously on pivoted arm can turn around transverse axis, completes the test of the measured light to suspention.Though fixed light source formula non-fully space distribution photometer can ensure the invariant position of measured light, but during test, pivoted arm with photo-detector stops by measured light suspension apparatus, the angular range on each about 30 degree of suspension apparatus both sides cannot be forwarded to, the total space cannot be completed measure, can not measure luminous flux, the light intensity tested out and photochromic distribution are the conclusions of segment space.Except above-mentioned defect, two kinds of distributed photometers, all can not carry out accurate adjustment location to the locus of measured light.
Summary of the invention
For the above-mentioned weak point of prior art, the present invention aims to provide a kind of fixed light source formula whole world space of planes distributed luminosity tester that can significantly improve measuring accuracy, its center that not only photo-detector can be allowed accurately to aim at measured light is tested, and measured light position can be allowed to immobilize, light source can be placed by actual working state, work continually and steadily under can keeping normal burning-point duty, realize the precision measurement of the luminous flux of the total space, light distribution and photochromic distribution on this basis.
