傳統(tǒng)的標(biāo)準(zhǔn)光源主要以白熾燈等連續(xù)光譜光源做標(biāo)準(zhǔn)源。隨著LED 等窄帶光源的使用越來越廣，傳統(tǒng)的方法已經(jīng)不能滿足LED 行業(yè)的計(jì)量、測(cè)試需求。主要表現(xiàn)為，由于標(biāo)準(zhǔn)源與被測(cè)物光譜不匹配造成的計(jì)量、測(cè)試誤差嚴(yán)重，給品質(zhì)管理和計(jì)量工作帶來很大的不便。

LED 標(biāo)準(zhǔn)光源的出現(xiàn)很好的解決了這個(gè)問題。可用于LED、LED背光模組、顯示、儀表等行業(yè)亮度計(jì)、色度計(jì)、CCD的校正計(jì)量。

With the help of stable LED-luminance standards it is possible to check the stability of your measurement equipment.

The stability of the luminance is realized through a temperature control with a Peltier-element and a intensity control with a spectral matched photo element. Only selected LED's in 5 mm housings are applied.

On customers demand also further colours can be realized. Therefore the customer has to choose in partnership with TechnoTeam the LED type of a conforming (or relating) 5 mm LED. Thus the LED type must be according necessary stability properties and furthermore must be chosen from a larger charge (appr. 100 LED's) of LED's with similar attributes (luminous intensity， colour， light spread charcteristics).
