This article is focused on the correct procedure to be followed to determine the value of responsivity while calibrating white LED lights on the Metrohm Autolab Optical Bench. This has three types of ...

Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor ...

While the brightness and color effect must be specified and implemented at the time of installation of conventional light sources, the arrival of white LEDs for indoor use presents the user with a ...

Video surveillance can be considerably improved by using LED lighting. The low-voltage, solid-state technology includes both infrared and white lighting capabilities, and the “green factor” of LED ...

Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related ...

Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light. Of course, that means that incandescent light bulbs are more ...

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 ...
