A light-emitting diode (LED) is a semiconductor device that emits incoherent monochromatic light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color depends on the semiconducting material used, and can be near-ultraviolet, visible or infrared. A...
LED (light-emitting diodes) light therapy comes in a range of colours for different wavelengths. Blue light is made up of the shortest waves and carries the most energy. Everyone knows about the blue light that comes from their screens that can keep you awake at night, however, in specific...
Thus a parameter like temperature dependencies was an irrelevance on former low current LED components (where the emphasis was very much on getting increased light-output were considered much more important) and is now, for High-Power Light Emitting Diodes, a predominant performance measure. ...
That is because the voltage drop from only half the diodes is less though the driver than with them all on, so it drives the working ones a little harder. This can possibly burn out the working diodes faster since they see a higher voltage. Out of all of the SixPars I have repaired...

The technological development of diodes that are used to make UV-LEDs has progressed rapidly worldwide, and it is expected that UV irradiation will become possible with a much higher output power [32,45,124]. The efficacy and effectiveness of UV-LEDs remain largely unknown, and further ...

As the name suggests, Handheld Light Therapy Device includes light-emitting diodes which are very therapeutic in nature. It was first developed by researchers at NASA to be used in space shuttles; however, due to its incredible healing effects, it soon became incorporated in most skin healing ...
Near-infrared phosphor converted light emitting diodes (NIR pc-LEDs), as a compact light source, play a constructive role in wearable optical biosensing devices. In order to detect the properties of different substances, the NIR emission should be as wide as possible. The typical strategy for br...
