Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

Light-emitting diodes (LEDs) 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 ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...
