![]() Series wiring doesn’t split the current, but instead powers one board before it powers the next (in series). After lighting the boards, the current exists through the negative connectors back to the driver (white an black wires).īecause current – even when it splits – continues to carry the same amount of voltage. Again, the current splits in two via the T-splice (red wires) that connects the positive connectors on each board. Here is another way to wire up two boards end-to-end on a double heatsink. In the above case we could use a HLG-240H-48A constant voltage driver to supply 48V to both boards and 5A divided between the two for 2.5A per board. The reason it is called a parallel circuit is because the current runs in parallel (splits into two or more) to power multiple boards.īecause the current splits into two, each board gets HALF the current, but ALL the voltage. It is wired the same as the first diagram. Here is a pre-wired board (red = positive, white = negative). Solid lines represent individual wires connecting the boards, while dashed lines represent current flow through the boards. Half the current lights the LEDs, while the other half flows through the top-right (+) connector where it exits and continues along the red arrows (external connecting wire) to power the top board.īy following the lines, you can see how the current splits up to power both boards before joining up again to flow back to the driver. The current from the driver on the left (red line) enters the bottom board at its top-left (+) connector and splits in two along the red-dashed lines. ![]() Note the two positive terminals at the top of each board, and the two negative terminals at the bottom. Here are two High Light boards, one above the other. You may click on the image to make it bigger/clearer. With this simplified concept, we can look at different ways to supply voltage and current to the LED board. That is why a minimum amount of voltage is required to drive a LED board, no matter the current. When you connect a positive charge to a LED board, the current flows through the LEDs, lighting them up, and continues until it completes its circuit back to the driver.Īs the current flows through the LEDs, the amperage doesn’t change – however the voltage drops. The difference between series and parallel wiring is relatively easy to understand once you know what the current is doing. Much of this information relates to the original High Light LED panels and DIY builds and is here for archival reference.
