The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...

This application note presents a closed light regulation loop using LED and MLX75305 in a minimal number of components. It provides a design example for prototype and evaluation, and describes ...

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL) ...

Jay Holben During one of my recent lectures, there was a great deal of confusion about how to adjust light intensity and when does light quality and/or color change when altering the intensity.

I wasn't sure the price was correct. Normally when I walk through Lowes, I check the price of LED bulbs. It seems they have always been between 11 and 15 dollars for the kind that would screw into a ...

If people are sleepless in Seattle, it may not be only because they have broken hearts. The American Medical Association issued a warning in June that high-intensity LED streetlights — such as those ...

A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up to 80 ...

The S18DLH and S22DLH high-intensity indicator lights are designed with highly visible LEDs to provide bright, clear indication in environments with high levels of ambient light, including direct ...
