LEDs are so common, they come in dozens of different shapes and sizes. The LEDs you are most likely to use are the through hole LEDs with two legs. There are lots of LEDs that are small and …
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 …
LEDs do not have a filament that will burn out, which makes them more efficient, durable, versatile, and longer lasting than the average light bulb. A common misperception is that the …
Reducing the chance of LED failure, LED drivers provide a more precise, regulated output current compared to a discrete-based circuit, but they also integrate overtemperature protection to …
LM-79-08, Electrical and Photometric Measurements of Solid-State Lighting Products, describes approved methods for measuring several attributes of LED products, including total flux, …
Examples of application circuits, circuit constants and any other information contained herein are provided only to illustrate the standard usage and operations of the Products. The peripheral …
Cree LED now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen maintenance. For information on the specific LM-80 data …
