Ever since its foundation in 2008, Innolumis has looked at outdoor space lighting in its own unique way. We combine our expertise in visual perception with the latest LED and lighting technology to create lighting that is not only functional, but also takes its surroundings into account.
Once started with exclusively green lighting, our knowledge and power of innovation has led to a wide range of more than ten different light colours.
These are divided into four lighting concepts, where the application can always be carefully tailored to the specific requirements of the location.
The diversity of our light colours is partly due to clever light source combinations of red, green and blue LEDs.
In this way, we can solve the often conflicting interests of people, flora and fauna. Yet a socially safe environment always remains the starting point, without compromising on road safety.
At Innolumis, in addition to LEDs based on RGB (red-green-blue), we also develop standard white LEDs. These white LEDs are nothing more than blue LEDs provided with a phosphor layer. These standard white LEDs are available at Innolumis in the variants 727 (2700K), 730 (3000K), 740 (4000K) and 750 (5000K).
Typical of these light colours is the high lumen/watt ratio, which contributes to energy-efficient and efficient lighting.
In addition, they have a colour rendering index (CRI) of 70, ensuring excellent colour recognition and a wide range of applications in public spaces. Thanks to these properties, these light colours are suitable for a variety of lighting issues where both efficiency and visual comfort are key.
Our eyes have two vision systems: one for daytime and one for darkness. These systems use two types of light-sensitive cells in the retina: cones and rods. Cones are responsible for colour perception and function best at high light intensities (photopic vision), while rods are mainly active at low light levels and cannot distinguish colour (scotopic vision).
Mesopic vision occurs in the transition zone between day and night, such as at dusk or low light levels in public spaces. In these conditions, both cones and rods work together, leading to enhanced perception of contrasts and shapes. This effect can be optimised by the right choice of light colours that respond to the wavelengths to which our eyes are most sensitive.
The so-called S/P ratio (Scotopic/Photopic) is an important characteristic of a light colour and indicates how effective the light is at low light intensities. A higher S/P ratio means our eyes can perceive more efficiently with less light, leading to energy savings and better vision in minimum illumination.
At luminance levels up to about 10 lux (about 0.6 cd/m²), our eyes are mainly sensitive to green and blue light. This explains why people can still see relatively well even in moonlight.
Innolumis therefore integrates an increased amount of green and blue in its mesopic light sources which significantly improves night vision. In addition, to maintain good colour recognition, red light is added.
Each Innolumis mesopic light colour has a specific application, but the basic principle remains the same; a high S/P ratio for more efficient energy use and optimal visibility at low light levels. Thanks to this technology, Innolumis offers an innovative and sustainable solution for public lighting, where energy savings and visual comfort go hand in hand.
Besides our range of standard and mesopic light colours, Innolumis also develops special light colours based on requests from the lighting market.
Governments, semi-governments and industry know us for our expertise in creating light colours based on certain spectra.
Thanks to the unique combination of special light sources combined with our patented reflector technology, we are able to create customised lighting solutions that meet specific needs and environmental factors.
This led to the development of the warm light colour Golden Orange, the bat-friendly BAT lamp and the migratory bird-friendly BIRD lamp.
Each of these lighting solutions is designed for a specific purpose such as improving visibility, minimising disturbance to flora and fauna, or optimising lighting in special environments.
In addition to our static light colours, Innolumis is also working on dynamic lighting solutions. This is, on the one hand, a dynamic solution based on red, green, blue and white LEDs (Dynamic RGBW) and, on the other hand, a lighting solution based on amber and white LEDs (Dynamic Amber-White).
This innovative further development makes it possible to adjust and control light colours remotely via a user-friendly dashboard. This provides additional flexibility and customisation for a variety of applications in public spaces.
The basis of this technology is an in-house developed 4-channel driver that allows the different colour LEDs to be controlled separately.
This allows governments, semi-governments and companies to easily respond to changing needs and conditions, from ambient lighting to functional adjustments for safety and visibility.
With this latest development, Innolumis takes an important step towards a future where light is not only energy-efficient and functional, but also dynamically and intelligently deployable within modern Smart City solutions.
