Q: Just as I understand the concept of color temperature (Kelvin), now CRI is being bandied about as LEDs come into the market. What is it exactly? A: I am right there with you. From the beginning of ...
How do you find the quality of the light a light bulb produces? Using the color rendering index, a measure of how well a light bulb illuminates a range of colors. Appliance Science looks at the ...
Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations. Start to look into LED lighting and quickly it becomes obvious that one type of LED ...
To create different lighting conditions, we used a special lighting booth consisting of LEDs with 24 different peak wavelengths. Three levels of correlated color temperature (CCT) *1 were employed: ...

When most people hear the phrase “adequate lighting” in an industrial setting, they immediately think about brightness and the level of visibility. Certainly, that’s important for employee safety.
(Nanowerk News) Luminescent ferroelectrics have attracted intense attention in flat-panel display, field emission display (FED), and vacuum fluorescent displays, which mainly focus on the ...
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 ...
