Led Wall ClocksLED Wall Clocks are becoming increasingly popular types of wall clocks as they offer some great wall clock designs and the LED wall clocks can really stand out in any room or office. LED wall clocks are also very easy to read and some of the most popular LED wall clock colours are red and blue. A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly being used for LED wall clocks. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness so your LED wall clock is bright and well contrasted. 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 colour of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. An LED is often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output. LED wall clocks are a type of digital clock and they do not have a small hand and large hand but have LED number displays to show the time, or date. Because they are driven electronically LED wall clocks are very accurate. Some popular examples of LED wall clocks is this Blue LED wall clock This unique LED digital wall clock features giant blue LED lights to give you the time. its a unique clock that is different from any other wall clocks. Made by the quality company Karlsson who make a range of fantastic designer clocks. The digital wall clock has a silver outer case which is filled with neon blue LEDs.

Most people hand with digital wall clock on the wall but it can be left freestanding to make a unique and outstanding feature in any room. To learn more about digital wall clock. LED wall clocks come in a wide range of designs and styles, and they offer a great alternative to the more traditional wall clocks with hands. The design of LED wall clocks tend to be modern and contemporary and they would look in many homes. There is a wide range of LED including: Large Led wall clocks Round LED wall clocks Square or rectangle LED wall clocks Designer LED wall clocks Modern LED wall clocks ...
