Independent constant current driving for each LED, reducing the systematic error, and improving the quality of aging.  

1    Constant current source drive.

2    Each LED chips are driven by unique independent constant current source, that means true constant current driving.

    Advantage: Independent constant current driving for each LED, reducing the systematic error, and improving the quality of aging.

3   The aging in the thermostat box is provided.

4   Driving current(5-120 mA) could  be adjusted continuously with wide output range.

5   Temperature range: -20-80oC
