ests and test requirements.
DC test
Figure 1 shows the DC test described in this article three test points.
Figure 1: Typical DC I-V curve of LED and test point
Forward voltage test (VF)
VF test test visible light LEDs forward voltage. Over the operating voltage, circuit current will result in a significant increase was significantly higher forward voltage, shown in Figure 1. A certain period of time (eg 1ms) the LED forward bias on the specific load current (eg 10mA), measuring the volt
