Part 3: What is DOB LED
Features of DOB LED: power source AC replaces AC/DC; high LED power efficiency; long lifespan
DOB stands for driver-on-board, and it should be noted that DOB LED is not an LED chip assembly technology but an LED PCB design option. The LED and IC chips are directly powered by utility power (110V or 220V). DOB LED circuit design leaves out electrolytic capacitors, inductors, transformers, and this design reduces the LED product size.
Since recent years, electronic components prices have been rising. The DOB LED PCB solution reduces the PCB parts and you can spend less on BOM materials for LED products.
