LED lights have taken over modern homes and workplaces. They're energy efficient, affordable, and marketed as the future of ...

White lighting LEDs are almost universally a combination of a blue light-emitting InGaN die and a phosphor that steals some of the blue light and converts it into a broad spectrum peaking at yellow or ...

You might have come across articles saying that the LED light bulb emits blue light which causes a myriad of harmful effects including damage to the retina, macular degeneration and disturbed sleep ...

The blue light in LED lighting that is increasingly used in our homes can damage the eye’s retina while disturbing our biological and sleep rhythms, a French health authority warned in a new report.

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 ...

LEDs inherently produce monochromatic light. An excited electron decays back to the ground state, releasing its energy in the form of a photon. The wavelength of this photon is defined by the band ...

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 ...

Exploring the evolution of LED lighting in cinematography, from red light solutions to the challenges of achieving deep blue and ultraviolet effects for more natural skin tones. It’s easy to assume ...
