傳統(tǒng)的標準光源主要以白熾燈等連續(xù)光譜光源做標準源。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)的計量、測試需求。主要表現(xiàn)為，由于標準源與被測物光譜不匹配造成的計量、測試誤差嚴重，給品質(zhì)管理和計量工作帶來很大的不便。

LED 標準光源的出現(xiàn)很好的解決了這個問題。可用于LED、LED背光模組、顯示、儀表等行業(yè)亮度計、色度計、CCD的校正計量。

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).
