The announcement followed the release of the RhodoLED XL red light-emitting lamp, to be used in combination with aminolevulinic acid hydrochloride topical gel, 10% for actinic keratoses. The ...

Chemists have developed a novel type of red phosphor material, which significantly enhances the performance of white-emitting LEDs. Chemists at Ludwig-Maximilians-Universitaet (LMU) in Munich have ...

This white paper will discuss Light Emitting Diode (LED) technology and its impact on television applications. It will highlight the advantages and challenges for these applications and will explore ...

URBANA - A retired University of Illinois physicist who worked with others to invent the world's first visible LED is questioning whether his work was ignored when two Japanese and a Japanese-born ...

The development of high-performance red-emitting phosphors provides new opportunities for fabricating white LEDs with both high colour rendering index and high luminous efficacy. White LEDs are ...

Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

We now take LED lighting for granted, but acheiving a specific colour is actually quite complicated. Why is that? At some point, reasonably soon, full-colour mixing will become more the rule than the ...

Once upon a time, the cathode ray tube was pretty much the only type of display you’d find in a consumer television. As the ...
