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 ...

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 ...

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 ...

Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

The FAN5607 constant-current parallel LED driver from Fairchild Semiconductor provides analog and/or pulse-width-modulation brightness control for LCD backlighting in ultra-portable applications. It ...

[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...

DURHAM, N.C.--(BUSINESS WIRE)--Cree LED, Inc. (“Cree LED”), an SGH company (Nasdaq: SGH), today announces the availability of three surface mount diode (SMD) LEDs optimized for large-format, ...

White light-emitting diodes (LEDs), the semiconductor devices underpinning the functioning of countless lighting technologies on the market today, were first released to the public in 1996. Following ...
