Abstract
Disclosed is a method for manufacturing an LED light bar and an LED light bar thereof. The method includes: providing a metal substrate and a plurality of LED lights; forming a graphene layer on the metal substrate in such a way that the graphene layer includes hollow sections formed to correspond to the LED lights; mounting the LED lights to the metal substrate in the hollow sections; and forming silicone layers in the hollow sections. The LED light bar includes a graphene layer formed on a metal substrate and silicone layers are provided for planarization and heat transfer so as to effectively enhance heat dissipation performance of the LED light bar and extend lifespan of the LED light bar.
