Product Details

Description

Led Vehicle Light Pcb is the product of PCB aluminum substrate (metal substrate heat dissipation plate including aluminum substrate, copper substrate, iron substrate), which is a low alloying al-mg-si system high plastic alloy plate with has good thermal conductivity, electrical insulation performance and mechanical processing performance.

Currently, the mainstream solution of producing LED fluorescent lamps is to use a lot of low-power high-brightness LED hybrid, commonly known as z string x combination. The larger the vEs difference is, the larger the current difference will be, which will lead to uneven LED brightness and even lead to the rapid decline of LED overcurrent.

After using Led Vehicle Light Pcb, the current voltage curve of each series can be bridged, and the current flowing through each LED is basically equal within a certain range of voltage fluctuation and Vs discrete range.
