LEDs that produce natural light for urban amenity lighting systems

LEDs that produce natural light for urban amenity lighting systems

The evolution of LED technology marks another leap forward with remarkable innovations regarding the quality of light that gets closer to daylight.

After reaching extraordinary results in terms of high luminous levels and LED efficiency, research is now concentrating on the quality of light emissions. The point of reference is the spectral composition of sunlight, which enables the best viewing of objects and colours and regulates the vital functions of our body. To make artificial lighting closer to natural daylight, new LEDs were created to reduce the presence of the blue component in the visible light spectrum, which interferes with our circadian rhythm (day-night cycle). With colour temperatures below 3000 K, the new LEDs emit amber light which is similar to dawn and that, compared to white light (4000 K), is better suited to certain contexts such as historic centres. White light remains the best choice for the lighting of busy streets, large areas and generally for all those places where brighter white light can ensure people’s safety and comfort.

The new Sunlike LED

An example of this new generation of LEDs is the SunLike technology born from the alliance between two global giants, the south Korean Seoul Semiconductor specialised in the back lighting of PCs, tablets and smartphones, and the Japanese Toshiba Materials that owns the Tri-R technology patent capable of keeping LED emissions within the spectrum of sunlight.

The goal of this new generation of LEDs is to reproduce a spectrum of luminous emissions that ranges from the cold light of dawn (4000K) to that of the midday sun (5000K) until the warm light of dusk (< 3000K). According to manufacturers, this new technology “will improve people’s quality of life, taking us to a world where lighting technology is people-centred”.

One of the most important characteristics of these LEDs is that the luminous spectrum allows a colour rendering that goes beyond classic parameters (CRI), with a greater definition of the details, as well as reflections and contrasts of each object.

Disano products with amber light

The amber colour, which resembles the light of dawn (2200 K), is proposed by Disano in its LED systems for urban amenity and street lighting. These systems emit a warm light that eliminates the risks of an excessive exposure to the unhealthy blue component of LED lights and has a minimal impact on residential zones and especially on historic centres.

With the new LEDs, it is possible to increase the energy efficiency of historic centres, without completely changing the evening atmosphere created by the yellow light of old lanterns.

This modern and sustainable lighting does not alter the images of our cities that we are accustomed to seeing during the evenings.

The new amber light that evokes the colours of nature is proposed in different fixtures for urban amenities and streets, with designs that range from the classic style of Lucerna and Vista to the more modern elegance of Loto and Metropolis.

 

LED and environmental protection

Another important aspect of outdoor lighting is the impact of fixtures and lights on the surrounding environment and nocturnal wildlife. Recent studies have shown that different types of lighting have certain effects on the life of insects and nocturnal birds living in the same eco-systems as the lighting systems. Environmental associations are striving so that this aspect is adequately assessed in the design of new lighting installations.

The new LEDs with a reduced blue component offer the possibility to use a less disturbing light in the streets or car parks near green areas, while respecting the wildlife.

LED lighting, which has proven its benefits in terms of environmental and economic sustainability, now can also confirm its ecological vocation. With Disano’s new LED lamps, technology is constantly more tailored to the needs of humans and the environment
