Rod LED modelsis mostly used aluminium PCB board. The aluminium printed circuit board realizes cooling faster. The characteristics of the printed circuit board of the LED bar directly affect the production cost.
The larger the PCB dimensions, the higher the cost. For this reason bar LED base dimensions varies. For example, 1.6 x 12 x 500 mmThe bar LEDs are available with base PCB dimensions of 1.6 x 16 x 500 mm or 1.6 x 16 x 495 mm.
