3.1 High Power White LED with high current- parallel power system integration

LED Strip 

Produced for testing dual DC / DC parallel supply system performance , using 3W High Power White LED ( rated current 750mA, Rated voltage 4.0V) to do experiments and performance testing of the drive , LED photo shown in Figure 4 .

 The high-power white parallel power supply systems, high-power white LED, data encoding module , Bias-Tee coupling module and key / indicator system integration , etc. , developed a dual function of both lighting and communication communication device ( see Figure 4b) use of the device , the power supply system is given a parallel experiment .

3.2 Lighting state flow characteristics of both experiments

Were set through the key driver output voltage of 0.5V, 1.0V and 3.0V, connect the white LED, respectively, read two DC / DC branch operating current I1 and I2, LED working voltage U0 and ends flowing through the LED the current I0, the test results shown in Table 1 .
