LED Technology: Advantages and uses in lighting

The LED lighting technology (Light Emitting Diodes) continue to benefit from a large spread in the domestic and international market, as eco-friendly alternatives to the traditional lighting technologies. This recognition of values ​​- ecologically, economic and functional - between producers and consumers, It means that the LED lighting market is clearly growing, according to the estimates and forecasts of the technicians. Only in Italy - as is clear from the "Efficient report & smart lighting reports "of Politecnico di Milano - the LED market will grow by 900 million euro of 2015 to over 1,5 billion euro planned for 2020.

The estimated growth investing, clearly, different fields of application. In the 2020 - to quote the above ratio - is estimated to be 400 million LED light sources to be used for home lighting. For that date, public lighting the LED lighting technologies should reach 3 and a half million, while in the industrial / service sector the market is expected to grow 80% compared to 2015, with the 20% of Italian industry to benefit from LED technology. The general framework would result in a total energy savings of 10,8 TWh per year.

Advantages and fields of use of LED lighting

As mentioned, among the most important fields of application of LED technology include those private lighting, public lighting, industrial, as well as the automotive industry. The advantages of its use touch on fundamental aspects such as energy saving, lowering maintenance costs connected to the useful life of the product, the quality of the luminous flux, in full compliance with the EU directive RoHS II. Specifically, we can mention the following LED lighting strengths:

Energy saving. All things being equal, it makes the LED light source stream absorbs a lesser amount of energy than the traditional lighting devices. Thanks to the large possibility of collimation, the luminous efficiency of LED devices is high in the face of reduced power consumption and a considerable reduction of CO2 emissions. It is estimated that for the same lighting, with the LED technology is obtained a superior energy saving to 50% compared to traditional technologies.

Dimming. The lighting control is one of the options offered by LED technology, maintaining the color temperature and the light exempt from any visible alteration, but with the possibility to divide the consumption depending on the needs.

LED street lightingEnvironmental Protection. The LED technology operates in full compliance with regulations 2011/65 / EC (Also known today as RoHS II Restriction of Hazardous Substances Directive) which replaced the 2002/95 / EC. This is because - unlike some older lighting technologies - in LEDs are no toxic or harmful materials for the environment, factor that positively affects the disposal of exhausted light sources. These sources, Furthermore, do not provide any emission of UV and IR radiation.

Service life and maintenance. If you fed with an adequate current and suitably cooled by a proper heat dissipation system, LED technology ensures a lifetime in the order of tens of thousands of hours. The considerably longer lifetime than traditional lighting technologies - such as incandescent and fluorescent lamps - implies that the frequency of replacement is very reduced, thus reducing maintenance costs of equipment.

Light quality. The light emitted from the LED light source has a high color rendering, critical to the perceptual activity of color by the human eye. Focal point of the LED technology chosen for the illumination of the road and in the automotive sector, the "white light" LED lets achieve effective and safe lighting with lower energy consumption.

Notes on the operation of the equipment

As mentioned, proper thermal management of LED lighting is the key to their duration; it is therefore necessary to provide for a cooling system / dissipation which allows to withstand the high temperatures technology. Moreover, to optimize LED technologies - and ensure their effectiveness in terms of operation and energy savings - are the basic quality and design of 'Electronic Boundary. The characteristics of electronic components - in terms of size and function - must be adapted to the LED product design, so as to ensure the proper management of the air flow, therefore a better yield of illumination, stability and, as mentioned, useful life and actual savings, energy and economic.
