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 ...

LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

The growing demand for color displays in cell phones, digital cameras and PDAs has created a huge market for white LEDs as backlights in these applications. Because white LEDs require low dc voltage ...

Sponsored by Digi-Key and Infineon Technologies: Today’s lighting systems are dominated by LED technology. Though it seems a relatively simple concept, lighting multiple LED arrays requires special ...

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 ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.
