Light therapy is one of the oldest modalities used to treat a variety of health conditions. The use of coherent light sources (like lasers) and non-coherent light sources (like light emitting diodes ...

I’ve been building up some microcontroller based miniature spy cameras using readily available tiny camera modules. Since I know an add-on infrared illuminator makes it easy to have better night ...

This color smart bulb enhances the night vision of your security cameras through infrared LEDs, even when it’s turned off. LIFX has taken its top-notch Wi-Fi color LED smart bulb and added a terrific ...

Ennostar and Taiwan Asia Semiconductor (TAS, formerly Opto Tech) are developing short-wavelength (over 1,000nm) infrared (IR) LED devices for use in biosensing including heart rates, SpO2, blood ...

Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of ...

Driver-monitoring systems (DMS) are becoming common in modern automobiles. Infrared (IR) cameras, utilizing an IR-LED in combination with a photo sensor, help recognize the hazardous microsleep that ...

Through use of an unique aspheric lens, the L8506 infrared (IR) light emitting diode (LED) emits a light beam with a directivity of just ±5°. The collimated light beam discharged by the IR LED ...
