Due to the lack of consistent international criteria for brightness measurement, a direct comparison of brightness data among different references is given. |
|
LED Dice could have different values of forward voltage VF and luminous intensity IV, two sorting operations are conducted in the process. |
|
| |
 |
| |
To selecte the LED dice which is used for production. During the procedure, we try our best to maintain both forward voltage and luminous intensity variations are minimal. |
|
| |
|
| |
The brightness variation for each device is minimized to an extent which is not significant to the human-eyes' visual effect. The second sorting is conducted after the LED Devices are fully assembled. during this process, the brightness of each device is measured and then sorted in a micro extent by BIN grade.
