Light-emitting Diodes: Research, Manufacturing, and Applications XI

Each bulb features a cluster of 48 light-emitting diodes (LEDs) and is bright enough to replace a 30 watt halogen, but only uses 2.5 watts of electricity. The bulb has a narrow beam angle of 45 degrees and is available in soft warm white (3,000K) and bright cool white (6,000K).

Accessible for professionals and hobbyists alike, this guide helps photographers navigate the transition from traditional flash and hot lights to light-emitting diode (LED) lights, the hottest new trend in lighting technology. The arrival of cost effective LED lights has facilitated radical advances in photographic science and required photographers to change the way they use lighting. This book explains how these innovations have influenced conventional light theory and offers a seamless transition...

PD ISO/TR 9241-309:2008: Ergonomics of human-system interaction. Organic light-emitting diode (OLED) displays £140.00 £119.00

Light Emitting Diodes (LEDs) are no longer confined to use in commercial signage and have now moved firmly, and with unquestioned advantages, into the field of commercial and domestic lighting. This development was prompted in the late 1980s by the invention of the blue LED, a wavelength that had previously been missing from the available LED spectrum and which opened the way to providing white light. Since that point, LED performance (including energy efficiency) has improved dramatically, and now...

MIGHTY BRIGHT XTRA FLEX SUPER LED BOOK LIGHT. With an extra long and extra bendable arm, you can now direct light more precisely than ever, with infinite beam positions! Its the eXtra accessory that no reader or traveller should be without! Illumination is extra smooth and even, due to a special lens over the single SUPER LED (Light Emitting Diode), which spreads light so evenly, there's no hot spot. The LED is as bright as 3 regular LED's yet delivers a soft sympathetic light ideal for reading.

The book will cover the two most important applications of semiconductor diodes - solar cells and LEDs - together with quantitative coverage of the physics of the PN junction at the senior undergraduate level. It will include: * Review of semiconductor physics* Introduction to PN diodes* The solar cell* Physics of efficient conversion of sunlight into electrical energy* Semiconductor solar cell materials and device physics* Advanced solar cell materials and devices* The light emitting diode* Physics...

Deliver startlingly clear images in a more eco-friendly way with the edge LED display. High on performance and reliability, yet low on power consumption, it is ideal for projects where no compromise is accepted.Experience an even dispersion of light with cutting edge LED technology. White LEDs (light emitting diodes) are positioned around the rim of the panel to give a more even spread of light. This results in even lower power consumption, less heat to dissipate, and a true, uniform color range...
