Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...

In contrast with HBLEDs, high-power LED modules (HPLEDs) offer far more compact form factors and can deliver lots of directional light. These characteristics have made HPLEDs extremely popular in ...

This article is excerpted from Section 21 of “Analog Circuit Design: Volume 3 – The Design Note Collection,” (ISBN: 978-0-12-800001-4), edited by Bob Dobkin and John Hamburger of Linear Technology ...

In high-power lighting, needs are emerging for LED luminaires rated to 100, 200 or even 600 watts (over 60,000 lumens), to cover wide areas. The higher-power heat sinks increase in size and weight ...

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 ...

Marl Optosource has announced the addition of a range of high power LED drivers to complement Lamina’s TitanTurbo, believed to be one of the world’s brightest LED light engine. LED light engines can ...

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 ...

Sharp has developed six high power led modules for its MiniZeni range. The modules are 15 x 12 x 1.6mm in size and are said to be suitable for numerous applications, such as office, commercial, street ...

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.
