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 ...

Suspected IR emitter for the PixMob units, mounted on a lighting tower (marked here in white). PixMob hardware has been known to change over time. This version has two RGB LEDs (an earlier version ...

Now, researchers have developed a new nanomaterial called nanoPE for street lights. This nanomaterial fulfills two key roles: efficient heat removal and enhanced light output. Moreover, these ...

Strategically placed deep infrared LEDs in high-wear facial zones fight ageing on a deeper level for excellent results. Many of the best LED face masks tackle the signs of ageing using red and ...
