No UV emissionsFigure 5.8.1:LED luminaires are attractive forillumination of delicate objects such asartworks as well as materials subject toUV degradation.LEDs emit light with negligible ultraviolet (UV) and very little infrared radiation. Small amount of radiated heat by LEDsmakes them appropriate for goods which are sensitive to heat. The lack of UV radiation (with appropriate design ofoptical part) makes them an attractive also for illumination of delicate objects such as artworks as well as materialssubject to UV degradation (Figure 5.8.1).Retail shop Food store Gallery5.9. Environmental impactUsing LEDs reduces environmental impact in several areas. Longer lamp life means that fewer resources are requiredfor maintenance. They also use no mercury and less phosphorus than fluorescent alternatives. These facts combinedtogether with high efficiency make LEDs a smart choice while reducing the footprint on the nature.5.10. Reliability and lifetimeFigure 5.10.1:Lighting evolution timeline.Unlike other light sources, LEDs don‘t “burn out”, they just slowly lose their light output over the time. LED luminairesdelivers highly efficient, long-lasting, high quality light with a lot of added values and no compromises. This factor isimportant in determining the lifespan of LEDs. Manufacturers are now stating lifetime to L70 – 70 % of installed lumenpackage. Lifetimes can vary depending on operating conditions (temperature, humidity), current, and type of LED.Primitive:FireWasteful:IncandescentInnovative:CFLEvolved:LED30LED ACADEMY/LED BENEFITS
