The adoption of LEDs continues to expand across a variety of sectors, including automotive, agricultural, industrial, commercial, and outdoor lighting. The biggest growth drivers are their lower power ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.

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 ...
