Note (1) LED current is measured by utilizing a high frequency current meter as shown below :
VL, IL
Light Bar Feedback
Channels
LED
Light Bar
Note (2) For better LED light bar driving quality, it is recommended to utilize the adaptive boost converter
with current balancing function to drive LED light-bar.
Note (3) PL = IL ×VL (Without LED converter transfer efficiency)
Note (4) The lifetime of LED is defined as the time when it continues to operate under the conditions at Ta =
25 ±2 oC and IL = 23 mA(Per EA) until the brightness becomes 50% of its original value.
