-
¤ý LED optical properties test underCIE-A/B luminous intensity measurement conditions.
¤ý LED optical properties testunder total luminous flux measurement conditions.
¤ýLED optical properties test to different angle by usingGoniometer.
¤ýCapacitance property test according to LED's biasvoltage.
¤ýForward voltage property test according to LEDÀÇ stressing current.
¤ýEach property test can be performed under the following conditions:
-
- Single measurement : Perform one time measurement DUT property under consistent environment.
-
- Temperature dependency measurement : Perform DUT property measurement to change of temperature.
- Current dependency measurement : Perform DUT property measurement according to stressing current.
¤ýAll measurements are performed by using high illuminance meter and spectrometer.
¤ýWhen using illuminance meter, perform accurate measurement viacolor correction.
¤ý Calculate absorption rate of DUT itself when measuring total luminous flux.
