Lets go back to our basic LED setup: one LED and one resistor connected from 5V to ground. This time we will duplicate it so that we have three LEDs except that each resistor is going to …

Photodiodes produce a leakage current that is directly proportional to the intensity of the light. This leakage current flows in the opposite direction to current in a normal diode or LED. Ex: As …

J Series® LEDs extend Cree LED’s industry leading portfolio of lighting class LEDs to a broader set of applications. With 14 available colors, the JE2835 N Class color LED family offers top …

Color quality is an important consideration when evaluating LED-based products for general illumination. This fact sheet reviews the basics regarding light and color and summarizes the …

Practical aspects of LED design, such as semiconductor materials, packaging techniques, and control systems, are examined to optimize performance and functionality.

To provide the method for measurement of lumen and color maintenance of LED lamps, light engines, and LED luminaires. To describe the procedures to obtain uniform and reproducible …

The materials used for the LED have a direct band gap with energies corresponding to near-infrared, visible or near-ultraviolet light. LED development began with infrared and red devices …
