    • ㆍ LED optical properties test underCIE-A/B luminous intensity measurement conditions.

      ㆍ LED optical properties testunder total luminous flux measurement conditions.

      ㆍLED optical properties test to different angle by usingGoniometer.

      ㆍCapacitance property test according to LED's biasvoltage.

      ㆍForward voltage property test according to LED의 stressing current.

      ㆍEach 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.

      ㆍAll measurements are performed by using high illuminance meter and spectrometer.

      ㆍWhen using illuminance meter, perform accurate measurement viacolor correction.

      ㆍ Calculate absorption rate of DUT itself when measuring total luminous flux.
