Spectral matching degree is also weaker than xenon lamp.The advantage mated with solar spectrum having in view of xenon source self, current sun optical mode
Intending device mainly uses xenon lamp as light source.But due to the attenuation problem of xenon lamp, it is usually in use hundreds of by 2000 hours at present
Afterwards, xenon lamp is changed, to ensure the precision of solar simulator.
Therefore, with high accuracy, economy, stability as principle, develop a kind of xenon lamp that can eliminate and decay the precision that causes
The solar simulator of decline problem, has certain economic worth.
Summary of the invention
The technical problem to be solved is: provides a kind of and can eliminate the precise decreasing problem that xenon lamp decay causes

99.9%.The light of LED output accounts for the 0.1%～20% of total specified irradiance.By the pulsewidth modulation of LED drive power is come real
The now accurate output to LED output light.Have in the solar simulator Systems Theory of the present invention at aging (the i.e. light of xenon source
The irradiance of the light that source sends declines, spectral shift) situation, by being automatically adjusted LED secondary light source, system is exported
Be basically unchanged to the irradiance measured on position, Spectral matching degree is basically unchanged.
The solar simulator of the present invention gathers irradiance and spectroscopic data by photosensitive probe, it is achieved simulate sunlight
Intensity of illumination and the Spectral matching degree of device output light detect, and feed back to master control system, more auxiliary by master control system regulation LED
That helps light source sends out irradiance degree, finally realizes the output of high-precision simulated solar irradiation.
The solar simulator of the present invention gathers the ambient temperature data of photosensitive probe by temperature probe, feeds back to master control
System, then revised, by master control system regulation, irradiance and the spectroscopic data that photosensitive probe measurement obtains, Systems Theory can disappear
Except the temperature impact on output light irradiance precision.
The solar simulator system of the present invention is in the case of the driving power supply of light source fluctuates, due to by photosensitive
Output light detection and the degree of closed loop feedback and master control system that probe realizes are automatically adjusted, and have power input voltage in theory
In the case of the fluctuation of little scope, system exports the irradiance of the hot spot measured on position and Spectral matching degree keeps constant.
It is an advantage of the current invention that: have xenon source aging (i.e. the light that light source sends irradiance decline, spectrum inclined
Move) situation, by be automatically adjusted LED secondary light source make system export the irradiance measured on position be basically unchanged,
The advantage that Spectral matching degree is basically unchanged, maintains stablizing of certainty of measurement；The LED light source life-span is long, and controllability is good, by regulation
LED reaches specified output light, it is to avoid the relatively high cost that frequent replacing xenon lamp brings；The present invention can eliminate temperature to output light
The impact of irradiance precision；In the case of having the fluctuation of power input voltage little scope, system exports the hot spot measured on position
Irradiance and Spectral matching degree keep constant.
