LED 标准光源的出现很好的解决了这个问题。可用于LED、LED背光模组、显示、仪表等行业亮度计、色度计、CCD的校正计量。
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.
| LED White | LED Blue | LED Green | LED Yellow | LED Amber | LED Red | |
|---|---|---|---|---|---|---|
| L (cd/m2) | 440 | 80 | 500 | 210 | 300 | 240 |
| x | 0.3300 | 0.1300 | 0.2000 | 0.5700 | 0.6400 | 0.6900 |
| y | 0.3200 | 0.0600 | 0.7200 | 0.4200 | 0.3600 | 0.3100 |
| λdom (nm) | 470 | 533 | 590 | 603 | 620 | |
| CCT (K) | 6300 |
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).
