A Light Emitting Diode (LED), with low power consumption, compact size, long life
duration and versatility, is ideal for lighting and illumination applications. LEDs have
found its applications in LCD monitor/TV backlights, street lighting, automobile
lighting, interior lighting, outdoors large screen displays, consumer electronics and
various other applications.
LED power drivers are used to provide the power to the LEDs, and are usually
designed as a constant current source due to the light emitting characteristics of
the LEDs. Although LED power drivers' functions and characteristics differ from
the general switch mode power supply (SMPS), the components used, the design
topology and the testing requirements are very similar. Chroma is able to provide
LED testing solution based on its twenty-five years of experience in providing power
electronics testing solutions. These solutions include : programmable AC and DC
Sources, high precision Power Meters, and LED Load Simulator specifically designed
for LED power drivers. Chroma is also able to provide Automated Test Systems suitable
for R&D, QA qualifications and mass production.

☑ Programmable internal resistance (Rr) for simulating LED ripple current (63110A)
☑ Fast response for PWM dimming test
☑ Up to eight channels in one mainframe

☑ Full Protection: OC, OP, OT protection and OV alarm
LED I-V Curve
IO
As a constant current source, the LED power driver has an output voltage range with a constant
output current. LED power drivers are usually tested in one of the following ways;
1. With LEDs
2. Using resistors for loading
3. Using Electronic Loads in Constant Resistance (CR) mode, or Constant Voltage (CV) mode
However, all these testing methods each have their own disadvantages.
Rd
VO
Figure 1 - LED V-I Characteristics
As shown on the I-V curve in figure 1, the LED has a forward voltage V F and a operating resistance (Rd). When using a resistor as loading, the I-V curve of the
resistor is not able to simulate the I-V curve of the LED as shown in blue on figure 1. This may cause the LED power driver to not start up due to the difference
in I-V characteristic between the resistors and the LEDs. When using Electronic Loads, the CR and CV mode settings are set for when the LED is under stable
operation and therefore, is unable to simulate turn on or PWM brightness control characteristics. This may cause the LED power driver to function improperly
or trigger it's protection circuits. These testing requirements can be achieved when using a LEDs as a load; however, issues regarding the LED aging as well as
different LED power drivers may require different types of LEDs or a number of LEDs. This makes it inconvenient for mass production testing.

Chroma has created the industries first LED Load Simulator for simulating LED loading with our 63110A load model from 6310A series Electronic Loads. By
setting the LED power driver's output voltage, and current, the Electronic Load can simulate the LED's loading characteristics. The LED's forward voltage and
operating resistance can also be set to further adjust the loading current and ripple current to better simulate LED characteristics. The 63110A design also has
increased bandwidth to allow for PWM dimming testing.
Figure 2 shows the current waveform from a LED load. Figure 3 shows the current waveform from 63110A's LED mode load function. From figures 2 and 3, the
start up voltage and current of the LED power driver is very similar. Figure 4 shows the dimming current waveform of the LED. Figure 5 shows the dimming
current waveform when using 63110A as a load.

The internal resistance (Rr) can be adjusted to simulate the LED power driver output ripple current. The traditional E-load can not simulate the ripple current
of LED shown as figure 6. Figure 7 shows the ripple current waveform from a LED load. Figure 8 shows the ripple current waveform from the 63110A LED
mode load function. Figure 9 and 10 show the turn-on waveform of using a resistive load and an electronic load. It is obvious that these waveforms are
very much different from the one with real LED (Figure 2). And it may cause the LED power drivers to fail as shown in figure 11, which causes it to go into
protection. Figure 12 shows the I-V curve of different numbers of LEDs, and figure 13 shows the I-V curve of different characteristics of LEDs those can
simulated by 63110A/63113A.
