High efficiency in LED lighting

The variables for a conventional LED luminaire are not many. LEDs, at least as far as the best producers in the world are concerned, are more or less all the same, the same can be said for power supplies. So what to do to improve efficiency? The easiest way is to write it in catalogs and that’s it, as many do, reporting efficiencies that often refer only to LEDs, without taking into account the losses due to temperature, lenses, glasses, power supplies which, added together , ranging from 20% for simple appliances, to 30%.
Another solution is to use plastic, low-power LEDs, which are very efficient but have a short life. The third way is to create innovative products, such as LuxLED.
In addition to many other characteristics, such as the lack of yellowing and resistance to high temperatures, silicone has a transparency of 94% against 92% of glass and 86% of PMMA; furthermore, since the primary lens of the LED is also made of silicone, it improves the LED-lens coupling and therefore efficiency. Result: silicone lenses lose 7-8% less than normal PMMA lenses or screens and 15-16% less than products equipped with lenses and protective glass.
VARIABLE POWER AND CONSTANT FLOW
All lamps, both traditional and LED, lose efficiency over time. To compensate for this loss, the power of the installed appliances is increased by 20-30%. In some LuxLED products the initial power of the luminaire is reduced by 18-20% and is automatically increased as the LEDs lose efficiency. With this solution, a constant luminous flux is obtained for the entire life of the luminaire and, above all, energy savings and an extension of the life of the LEDs by 9-10%.
LuxLED luminaires, industrial line, “D” versions, for indoor use, are equipped with an ambient light sensor, managed by a microprocessor that reduces the power of the luminaire when the natural light illumination exceeds the set threshold. This solution allows a significant reduction in consumption throughout the year, with an average saving of 20-25%.
Applying all these technologies to a 200W LED luminaire, which normally replaces a traditional 400W lamp, reduces the average consumption to less than 100W. In practice, if, with a 160W LED luminaire there is a saving of over 200W, by applying LuxLED technologies the saving is over 265W. Basically, even if the technological device cost 50% more than a traditional LED device, the payback times would still be the same but the subsequent gains would be much greater. We remind you that 100W less consumption means, during the life of a device, an energy saving of at least € 1,200. All this at a price slightly higher than common LED luminaires.
