Hauv av hnub ci hluav taws xob cuam tshuam zoo heev los ntawm ib puag ncig xws li huab cua, sijhawm, thaj chaw, thiab huab cua. Nws yog ib qho nyuaj kom tau txais kev ruaj khov, rov ua dua, thiab tswj tau lub hnub ci hauv lub sijhawm, thiab nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm kev sim ntau, ntsuas ntsuas, thiab ntsuas kev ua haujlwm. Yog li ntawd, lub hnub ci simulators feem ntau siv los ua kev sim lossis ntsuas cov cuab yeej los simulate lub cev thiab geometric zog ntawm hnub ci hluav taws xob.
Lub teeb-emitting diodes (LEDs) tau maj mam dhau los ua lub teeb kub kub rau lub hnub ci simulators vim lawv cov kev ua haujlwm siab, kev tiv thaiv ib puag ncig, kev nyab xeeb thiab ruaj khov. Tam sim no, LED hnub ci simulator feem ntau paub txog kev simulation ntawm 3A cov yam ntxwv ntawm lub dav hlau tshwj xeeb thiab hloov pauv hauv av hnub ci spectrum. Nws yog ib qho nyuaj rau simulate lub geometric yam ntxwv ntawm lub hnub ci raws li qhov yuav tsum tau ntawm lub hnub ci tas li (100mW / cm2) illumination.
Recently, Xiong Daxi's team from Suzhou Institute of Biomedical Engineering and Technology, Chinese Academy of Sciences, designed a distributed high thermal conductivity single crystal COB package based on a high-power vertical structure narrow-band LED light source to achieve a stable output of high optical power density.

Nyob rau tib lub sijhawm, ib txoj hauv kev tsom rau lub teeb nrog tag nrho aperture ntawm siab -lub zog LED los ntawm kev siv super- hemispherical chiming lo ntsiab muag, thiab cov txheej txheem nkhaus ntau- qhov tseem ceeb collimation system yog tsim los ua kom tiav cov collimation thiab homogenization ntawm tag nrho -spectrum teeb qhov chaw nyob rau hauv lub ntim qhov ntau. . Cov kws tshawb fawb tau siv polycrystalline silicon hnub ci hlwb los ua cov kev sim tswj ntawm lub hnub ci sab nraum zoov thiab lub hnub ci simulator nyob rau hauv vaj huam sib luag, xyuas qhov tseeb spectral thiab azimuthal sib xws ntawm lub hnub ci simulator.
The solar simulator proposed in this study achieves class 3A illumination with 1 solar constant irradiance in a test plane of at least 5cm x 5cm. At the center of the beam, within the working distance of 5cm to 10cm, the irradiance volume spatial inhomogeneity is less than 0.2 percent , the collimated beam divergence angle is ±3 degree , and the irradiance time instability is less than 0.3 percent . Uniform illumination can be achieved within the volume space, and its output beam satisfies the cosine law in the test area.

Tsis tas li ntawd, cov kws tshawb fawb kuj tau tsim kho lub hnub ci spectrum haum thiab tswj software, uas thawj zaug paub txog kev simulation ntawm lub hnub ci hauv av thiab lub hnub ci kev taw qhia nyob rau hauv cov xwm txheej sib txawv. Cov yam ntxwv no ua rau nws yog cov cuab yeej tshawb fawb tseem ceeb hauv kev lag luam hnub ci photovoltaic, photochemistry, thiab photobiology.

Cov txiaj ntsig kev tshawb fawb tau luam tawm hauv Hnub Ci Zog hauv qab lub npe ntawm LED-raws li hnub ci simulator rau lub hnub ci hnub ci thiab kev taw qhia.
