So where it was once advantageous to opt for serial connected LED arrays for display backlighting, today the concept of using parallel circuit configurations is a viable alternative.

High-side pass elements are preferred, especially in automotive uses, because they let you connect only a single current-limited wire (chassis return) to the load. To configure parallel drivers ...

To overcome that, a team at KIT's Light Technology Institute developed a method to inter-connect the LEDs that allows for the circuit to stay lit up if individual diodes fail. In doing so ...

Most commercial LED flashlightsuse three AAA or AA batteriesin series that produce 4.5V. The batteriesthen drive four white LEDs that connectin parallel. These LEDs can ... Figure 1 This circuit lets ...

These drivers, one suited to series- connected LEDs and the other to parallel-connected LEDs, deliver up to 80 percent efficiency. The SiP12401 boost controller IC, working from a 1.8- to 5-volt input ...

However, this is a great time to look at the difference between series and parallel circuits ... you can make a similar circuit with 10 or 20 bulbs. Just connect them all in a line so that ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant ...
