LED Materials

LED (Light Emitting Diode)

      LED is nothing more than a light emitting diode (LED) in other words is a semiconductor light source. The LED lamps are used as markers in many devices and are increasingly used for different types of lighting. It has established itself as a practical electronic component for several years. In 1962, the LEDs emit low-intensity red light, but in modern versions they are available in all the visible, ultraviolet and infrared wavelengths, with very high brightness.

The Function of LED

     When a light emitting diode is switched on, electrons are able to recombine with holes electrons inside the device, resulting in the release of energy in the form of photons. This is the phenomenon of electroluminescence and the color of light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. The LEDs now have many advantages over the bulbs, including the lowest power consumption and longer life, improved durability, their smaller size and faster switching colors.

Use of LED

      The LED (Light Emitting Diodes) are used in various applications such as aviation, lighting of the car in advertising, general lighting, but also on traffic signs. The LEDs gave us the oportunity to have new types of text, video screens, live video and is also useful in advanced communications technology. Infrared LED lights are also used in remote control units of many commercial products, including televisions, DVD players, and other household appliances.

LED Sighns

      LED because of its many advantages over the simple lighting, such as those of lower energy consumption, longer life, improved durability, their smaller size and faster switching colors, predominantly used in the manufacture of lighting signs in generall. In particular we find in the manufacturing of LED text displays, big and small inscriptions and pharmacy crosses. All these structures are generally composed of the mettal box, LED strips and the necessary power transformers. Hellas LED is a company that has established its business in the field of lighting signs and LED since 1966. We cooperate with and provide technical products only for signs manufacturers. Our partners are amongst the largest in Europe. Contact us to inform you about the quality and wide range of LED materials available for the professionals in lighting and signs.
