LEDs for lighting represent a very recent technology, strongly developing and subject to continuous progress. T the three-year period 2010-2012 has been a period of considerable progress in the knowledge of this technology and has led to the final resolution of problems related to the luminous flux, efficiency, color rendering and “binning”.
Designers are constantly searching for even higher performance in order to replace all traditional light sources with higher energy consumption with low consumption LED products. Optimization of lighting bodies to allow the adaptation of new conveyor lighting sources to all situations in which lighting systems are used.
The commercialization of new materials and the new available technologies have made LEDs ready to invade the market on a large scale, the progress in diffusion is fast and constantly increasing.
Commercial activities, shops and hotels, but in general all those activities with ample opening hours to the public, were the first to grasp the value of the multiple benefits offered by this new technology and today drive sales of LED products worldwide. An important part, in fact, of the current market of LED products is constituted by the simple replacement of old bulbs on already existing plants with new bulbs with higher performance (Retrofit or Regeneration).
To date, this is actually the fastest and most economical operation to reduce electricity consumption for conveyor lighting in a short time without having to deal with much more expensive modification work on the electrical system and the lighting system.
The advantages of LED lighting technology for conveyors
The LED is a very high efficiency source (100lm/W) which allows a high energy saving compared to all incandescent sources. The average life, up to 20 times higher than traditional lamps, makes it the source with the lowest maintenance cost.
The life of the LED is around 50000 hours when applied in confined spaces, as in built-in appliances or for retrofitting, against the 20000-30000 hours of traditional sources. In open spaces, as for outdoor applications, the service life may be even higher. All this involves less frequent maintenance and replacement.
Throughout his life he has the highest color stability and allows the widest choice of light shades in lighting. No light emission in the infra-red and ultraviolet bands with consequent reduction in the quantity of heat produced, light beam without damage to health and suitable to illuminate even the most delicate objects.
Instantaneous ignition and high variability of the power engaged according to use (dimming). Allows extreme freedom of design to manufacturers thanks to the minimum size of the LED chip.
