UB1104B blue shines at up to 100 mcd, the UG1104B blue-green at up to 300 mcd, and the AlInGaP FR1104B red and FY1104B yellow LEDs at up to 70 mcd. Device features include a power dissipation of 80 to ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...

WEST LAFAYETTE, Ind. - A Purdue University study shows that targeting plants with red and blue LEDs provides energy-efficient lighting in contained environments, a finding that could advance the ...

I FUCKING HATE BLUE LEDS.<BR><BR>Actually. I don't hate the actual LEDs themselves. I hate it when they have been incorporated into something purely for the BLING ...

Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found ...

We developed a hybrid copper–iodide compound called CuI(Hda). It emits deep-blue light at about 449 nanometres and has an almost-perfect photoluminescence quantum yield — a measure of emission ...

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...

The three Japanese scientists who invented the first efficient blue LEDs in the mid 1990s have received the 2014 Nobel Prize in Physics. The invention of efficient blue LEDs was a foundational step in ...
