Infrared LED flashlights can be acquired at relatively low cost, but where’s the fun in that? To that end [johnaldmilligan] spent a couple hours building an infrared flashlight-gun with an LED ...

The project uses 940nm infrared (IR) LEDs embedded in clothes to overwhelm photo diodes in IR-sensitive cameras used for surveillance. Since the wavelength of the lights are not visible to humans ...

Infrared Light Emitting Diodes (IR LEDs) are a type of LED that emit light in the infrared spectrum, which is invisible to the human eye. These LEDs are typically used in applications where infrared ...

Light emitting diodes (LEDs) are PN junction devices that give off light radiation through electroluminescence when forward biased. They are used as various indicators in aviation, automotive and ...

EPIGAP OSA Photonics GmbH, a leading global manufacturer of custom and standard LEDs and photodetectors, announces an ...

So, what’s the deal with LED masks? Using light therapy (think red, blue or even yellow light), these masks penetrate deep ...
