tail lamp
1, you can use ICT to detect the voltage of the whole or more or more circuits. Detect and test missing parts, dead lights, virtual welding and broken wires.
2. Detect the damage of LED internal chip by the low current (generally below 10uA) and the high current 20mA on the upper constant current source.
LED lamp bead type
1, first use voltage measurement to detect LED missing parts, poor raw materials, virtual welding, broken wires, etc., and you can also use LED module in ICT to detect color, brightness, chromatic aberration, etc.
2. The LED light array can use ICT+CCD to detect the LED status.
