Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

Lighting Science Group Corporation designs, develops, and markets general illumination products that use light emitting diodes (LEDs) as their light source for retailers and original equipment ...

Have you ever wondered how a tiny LED light can produce such brilliant illumination with almost no heat and very little energy? In this video, we dive deep into the fascinating world of Light Emitting ...

Abstract: We propose a non-contact method for determining phosphor/silicone temperature (phosphor temperature) in phosphor-coated light-emitting diode (pc-LED). The pc-LED with a surface mounted ...

The proximity of the light-emitting diodes to the skin surface is crucial for optimal results, so you need a design that fits your face well. As for which style of device is right for you, see below.

We report the high-frequency modulation of individual pixels in 8 × 8 arrays of III-nitride-based micro-pixellated light-emitting diodes, where the pixels within the array range from 14 to 84 μ m in ...

For most people, LED masks are safe, but you’ll want to talk to a dermatologist first if you have an existing skin condition. These light therapy devices have the potential to smooth wrinkles ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

Organic light—emitting diodes are a technology that is used in most modern electronic devices. For example, each pixel of the display is a small "light bulb" that glows when an electric current is ...
