With their small size, efficiency, new lighting quality and constant innovation in applications – LEDs dominate the world of light. From light-emitting diodes to high-quality general lighting and display instruments, their development is exponential. The LED has become an indispensable tool.
Since Edison invented the incandescent bulb, LED is the most significant invention in the history of lighting technology. The light of the future is now illuminating our present and it is everywhere, both indoors and outdoors. LEDs improve street lighting at night, LED headlights increase road safety, and indoor LED lighting is experiencing a revolution with new systems, long life and high efficiency.
LED lights are extremely efficient and have a remarkable energy balance. LEDs consume little electricity and have a higher light output than similar luminaires with conventional light sources.
Luminous efficiency indicates the electrical power (watt) transformed into light (lumen) by a light source. Common halogen lamps provide up to 30 lm/watt, fluorescent lamps between 60 and 110 lm/watt and LEDs currently reach 200 lm/watt. LEDs are constantly being improved.
Compared to an old installation with T26 light sources, a new installation with LED luminaires can achieve energy savings of up to 65%. This excellent result is a strong argument in favor of the use of LEDs.
In combination with state-of-the-art lighting management, they can save up to 85% of energy. A convincing cost factor!
Users will benefit from lower electricity bills: for a lower electricity consumption, n LED luminaire provides a higher light output than a similar luminaire with conventional light sources – without any compromise on performance and reliability.
Compared to conventional light sources, LEDs have an extremely long lifetime of over 50,000 hours. Extrapolation of consumption data shows a lifetime of 18 years for LEDs based on 250 working days per year and 11 hours of operation per day! Unlike conventional light sources, LED modules do not fade out immediately, but rather their brightness gradually decreases. The luminous flux and therefore the luminous intensity decrease slightly over the period of operation. For this reason, it is important to distinguish between power loss and complete shutdown of the LED.
External factors have an impact on the lifetime of an LED. Operating and environmental temperatures affect the luminous flux and can shorten the lifetime. The colder the environment, the more efficient the operation of LEDs. For this reason, all RIDI LED lights have optimal thermal management to ensure maximum life of the installed LEDs.
The impact of light on people is multiple. Our perception is 80% visual and therefore dependent on light. Light also acts on our internal biological clock and, therefore, on the physiological and psychological processes of the human body. Light is life, light is quality of life! Light can arouse or even control emotions, light has a direct effect on people’s health.
Thanks to its outstanding lighting properties, modern LED technology represents a considerable added value, as it allows lighting to be adapted to individual needs. Since LEDs are electronic components, they can be precisely controlled and are ideally integrated into a lighting management system.
Dynamic control allows the evolution of natural light to be reproduced and reinforces the biological rhythm of people at work or in study periods. The color of the light and the intensity of the lighting play a significant role. LEDs, in particular, have a high color rendering index and, therefore, are intended to create everything from a cool, bright morning light that promotes concentration to a relaxing evening light. In health care and senior care, light is an essential element, it is a factor of well-being and health improvement.
LEDs do not emit harmful UV or infrared radiation, they are mercury-free, and the light delivers its full power as soon as it is switched on.
LEDs are superior to conventional light sources not only in terms of technology and efficiency, but also in terms of their small size. LED lighting systems can be configured in countless ways. The free forms and minimal dimensions of the luminaires provide architects and lighting designers with a huge reservoir of new possibilities for integrating light into architecture. The light can enhance a room or dominate it, and its presence can also be imperceptible in the background while providing good visual conditions. The very good color rendering of LEDs and the visual perception of strong colors create a lighting atmosphere adapted to people’s needs.
LED technology can also be used to achieve outstanding surface lighting and shadowless lighting or canopy lighting.
LEDs are increasingly used for the main lighting of offices or industrial buildings. The possibilities in this area are truly fascinating.
