A manufacturing method of an LED light bar and the LED light bar. The manufacturing method comprises: step 1, providing a metal substrate (20) and a plurality of LED lights (40); step 2, forming a graphene layer (60) on the metal substrate (20), the graphene layer (60) being provided with hollow parts (62) corresponding to the LED lights (40); step 3, installing the LED lights (40) at the positions of the hollow parts (62) on the metal substrate (20); step 4, forming silica gel layers (80) at the positions of the hollow parts (62). According to the manufacturing method of the LED light bar and the LED light bar, the graphene layer is formed on the metal substrate, flattening and heat transfer are conducted through the silica gel layers, the heat dissipation effect of the LED light bar is effectively improved, and the service life of the LED light bar is prolonged. La présente invention concerne un procédé de fabrication d'une barre lumineuse à LED et la barre lumineuse à LED. Le procédé de fabrication compren
