Dynamic White Light

Mitigating the effects of artificial night lighting and change the perception of an environment

Dynamic White technology is an extremely flexible solution for achieving lighting that can change over time. Modulating light colour and intensity, the effects of artificial light at night on the environment can be mitigated and the perception of a space can be modified.

The spectral distribution of white light can be adjusted from very warm light (CCT=1800K) to colder light (CCT= 4000K). Light colour modulation is complemented by the option of adjusting the intensity of the flux emitted at different colour temperatures.

Dynamic White optical systems are available with different optical distributions to enable the illumination of spaces, paths and architecture in urban and suburban contexts.

The effects of lighting colour temperature on ecosystems

Approximately 30% of vertebrates and 60% of invertebrates are nocturnal, and artificial night-time lighting disturbs these animals by altering their movements, dietary balance and mating frequency. Tests have been conducted to compare the behavioural responses of various animal species to the different wavelengths in a range of light sources with varying spectral power distributions. The results of these show that, in general, light sources with a lower colour temperature (CCT) have less impact.

Most nocturnal animals, in fact, are particularly sensitive to the blue component of light and, therefore, cold lighting causes greater problems of disorientation, attraction and altered predator-prey relationships.

Emissions in the blue and red region are also able to generate a negative physiological response in plants by prolonging photosynthesis at night and modifying growth processes.

The effects of lighting colour temperature on the visual performance of humans

The purpose of artificial nocturnal lighting is to make outdoor spaces safe for people. In most artificial night-time lighting scenarios, humans experience a phenomenon called mesopic or twilight vision, caused by the responses of a combination of light cells in the retina called cones (photopic photoreceptors) and rods (scotopic vision photoreceptors).

The spectral response of mesopic vision has a wavelength peak of 507 nm (blue-green).

Cold light with provides lumen that are visually more effective for our eyes to process and is therefore better in terms of nocturnal visibility.

The effects of light colour temperature on the perception of the nocturnal urban landscape

Dynamic White optical systems offer designers the opportunity to choose a precise tonal gradation for the lighting in each illuminated area.

The colour temperature of the lighting in an environment affects people’s emotional reactions and behavioural responses.

So, Dynamic White technology can be used to improve the urban mood and encourage interaction between people.

Dynamic lighting also gives each location a changeable identity that can be adjusted to meet specific needs. The colour and intensity of the light can alter to match seasonal colour variations, make an urban space more attractive or tell specific stories.

Regulating lighting

TIMERS

Timers allow the colour and intensity of lighting to be adapted to different time periods. They are factory programmed at the customer’s request and can be changed by qualified personnel accessing the luminaire. Each individual light point operates independently and no additional devices are required.

REMOTE MANAGEMENT

Remote management systems allow the colour and intensity of lighting to be changed for different time periods or other requirements with extreme flexibility. Programmed settings can be changed easily by the customer using software installed on a remote device. Remote management allows several light points in the same system to be managed simultaneously.

MOTION SENSORS

Motion sensors detect human presence or vehicular traffic and adapt the colour and/or intensity of lighting to the needs of the moment. The devices comply with Zhaga standards. They operate in both independent and shared mode with the surrounding lighting points.
