What is LED? Led: How do they work?
An LED is a semiconductor device that converts electrical energy into visible light.
When it is powered (polarization), the electrons move through the semiconductor and some of them fall into a lower energy State. In the process, the energy “spared” is issued in the form of light.
Technological research allowed the achievement of more than 160 Lm/W for high power LEDs. Although not available in production, this level of performance shows that the LED technology has not yet reached its peak.
The variety of colors, the compactness and flexibility of the modules ensures ample creative possibilities in the various applications. LED modules lit routes and outline, color effects and ensure greater safety in road signs.
The gradphysics sees the appearance of high (CRI 90) and color temperatures from 2700K to 6500 k.
Brightness uniformity and color rendition of the LEDs were improved so much that today are increasingly being used for the purpose of enlightenment itself.
The LED modules are composed of a certain number of LEDs mounted on a PCB (rigid or flexible) with active or passive current control devices.
Depending on the scope you can also add optical or light pipes to get different beams and light distribution.

Led: the development of new solutions
The LED stands for LIGHT EMITTING DIODE (light emitting diode) component that emits monochromatic light to electric current. The LEDs are putting new and exciting tools available to the work of the lighting designer, making it possible to create imaginative lighting products and narcotic effects once technically impossible.
For the first time advances in LED technology have enabled high quality lighting is coloured white for both indoor and outdoor applications.
