High-power industrial Light Emitting Diode (LED) fixtures use series-parallel strings of High Brightness (HB) LEDs to produce superior lighting fixtures compared to traditional, "ballast-based" ...

Multi-die packages are flavour of the month among the high-power LED manufacturers. Certainly for both manufacturers and designers chasing the title of “highest lumen output” device, this approach ...

A new series of LED Quarterly Insights reports, produced by the publishers of optics.org, kicks off with an in-depth analysis of the latest advances in high-power LEDs. The pace of development at the ...

High power LED applications like automotive headlights, general lighting, or pocket projectors demand ever increasing brightness. High driving currents yield high brightness, but as the current rises, ...

[Devon] recently repaired a handful of Phillips LCD projectors which he was quite excited to use. The only problem is that he didn’t want to mess with replacing the bulbs after every 2000 hours of use ...

There are extremely high powered LEDs out there, and most of the ‘creative’ uses of these are extremely high-powered flashlights, complete with heatsinks, forced air cooling, and beefy power supplies.
