Abstract
A method for manufacturing an LED light bar includes steps: a nozzle picks up LEDs pending to be mounted; the electrical parameters of the LEDs detected by the nozzle are stored in a database; then, the nozzle disposes the LED on a substrate; the above steps are repeated until a plurality of LED branches are mounted on the substrate; then, differences of the electrical parameters of the LED branches are calculated according to the electrical parameters in the database; the positions of the LEDs of the LED branches are adjusted to make the electrical parameters of the LED branches equal.
