WHAT IS LED
The LED stands for Light Emitting Diode as stated on Abbreviationfinder, is a source of light of last generation that has as its basic unit a diode formed from several layers of semiconductor material that crossed by direct current, in the active layer, produces light. The light produced in this way is separated directly by reflection.
The LED produces a light of a specific color in contrast with conventional light sources that generate a spectrum of colours continuously. The color produced by the LED depends on the semiconductor material used. For this reason they are used different types of semiconductor crystals, which crossed from current generate different colors. The typical white light LED can be obtained by applying a layer of yellow fluorescent material (phosphor) to blue LEDs or through the compositions of red, green, and blue diodes. In the second case we speak of RGB (Red-Green-Blue) that is often used for decorative purposes seen to various effects that can be played.
- Useful life: is normally estimated at 50,000 hours (17 years with 8:00/gg). Because the LED it collapses suddenly but gradually loses brightness over time, at the end of the period indicated above the stream will be greater than or equal to 70% of initial brightness
- Maintenance costs: are drastically reduced compared to traditional sources; For example, in the order of 1 LED lamp against halogen substituted 20
- Energy saving: is of 85% compared to incandescent or halogen sources and from 40% to 60% compared to fluorescent and discharge lamps
- Quality of light: (CRI) indicates the color fidelity; In the case of LEDS also reaches very high levels up to 95 on a scale with a maximum value of 100
- NoUV: the LED while preserving the integrity of thermal radiation because it doesn’t emit IR illuminated products talking ultraviolet
- Ignition: Peculiarities of traditional sources such as fluorescent LED with respect to the instant download and you and especially the adaptability to numerous shutdowns to ignitions without causing any damage.
- Depreciation: thanks to energy saving and maintenance obtainable, investing in a new LED lighting system, even in lieu of a traditional, is amortized in a short time
- Size and applicability: The LED comes in many shapes and sizes also has a much smaller as well as characteristics such as flexibility that allow him to push the limits of application of conventional light sources.
- Investment: Although initially LED systems have higher costs of conventional light sources thanks to energy saving, low maintenance costs and extremely long life, savings in travel time between 50% and 80%.
- No hazardous substances: LED luminaires unlike other traditional sources contain no possibility of hazardous substances and therefore in line with the EU RoHS Directive 65/2011/.
