Product Description

ultraviolet and infrared wavelengths, with very high brightness.
When a light-emitting diode is forward biased (switched on), electrons are able to recombine with electron
holes within the device, releasing energy in the form of photons. This effect is called electroluminescence
and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the
semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be
used to shape its radiation pattern.[4] LEDs present many advantages over incandescent light sources
including lower energy consumption, longer lifetime, improved robustness, smaller size, and faster
switching. LEDs powerful enough for room lighting are relatively expensive and require more precise
current and management than compact fluorescent lamp sources of comparable output.
Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive
lighting (particularly brake lamps, turn signals and indicators) as well as in traffic signals. LEDs have
allowed new text, video displays, and sensors to be developed, while their high switching rates are also
useful in advanced communications technology. Infrared LEDs are also used in the remote control units
of many commercial products including televisions, DVD players, and other domestic appliances.
