Let our light tell you a story - light is so much more than lighting.
Human Centric Lighting
Light is not just for visual orientation. Certain wavelengths in light influence psychological processes, such as the ability to concentrate and perform, the hormone-controlled waking-sleep rhythm and general well-being.
Human Centric Lighting means adapting lighting to the specific needs of the user to achieve maximum quality of light and lighting. TRILUX offers individual solutions for varying needs. Four different application possibilities exist according to the desired light effect.
4 facets of HCL
The spectral composition of natural light changes during the course of the day. This change stabilises the circadian rhythm of people. A circadian lighting system modifies its spectral composition during the course of the day analogue to daylight, thus supporting the waking-sleep rhythm.
Light with a high blue component (cool white) has an activating effect on the organism. It increases cognitive performance and allows better concentration.
Light with a high red component (warm white) has a psychologically relaxing effect.
Warm white, cool white or coloured light: the needs of users are often very individual according to the situation. An HCL solution for example enables users to adapt the room atmosphere to the specific mood by selecting the appropriate light colour and light intensity.
Human Centric Lighting systems
Varying application options demand various systems and the right lighting solution must be implemented to ensure that Human Centric Lighting functions effectively and convincingly. TRILUX essentially differentiates between four system approaches:
Circadian daylight-synchronous systems
These solutions are oriented to the 24-hour rhythm of daylight, simulating this based on various colour temperatures and intensities. Such systems can be generally used in all applications.
These track rhythms oriented to individual requirements instead of the course of daylight? Activating light at 11.15 am and a relaxing light atmosphere at 2 pm each day? No problem.
Manually controlled systems
These generate melanopic-effective lighting according to requirements that serves either for relaxation or activation. Such systems are ideal for tasks not dictated by time schedules.
Such systems use lighting with coloured light (RGB-controlled) or special white tones and create emotions, experiences and accenting.
Offices are one of the most effective applications for melanopic-effective lighting. Such lighting improves levels of concentration, creativity and the capacity for performance. These effects are due to calming as well as activating light and it‘s a matter of achieving the right balance.
TRILUX recommendation for offices:
circadian daylight-synchronous systems
These support the natural daytime rhythm of people without having to do without presence detection and dimming for optimising efficiency. Such systems create performance-oriented, pleasant working atmospheres which remain effective into the evening hours and also set the course at the end of the day for a relaxing night.
TRILUX recommendation for conference rooms:
manually controlled and emotional systems
Tense discussions, quick-tempered contractual negotiations and presentation-based displays – each situation requires the right lighting. Manually controlled systems supplemented with emotional light achieve this balance.
In the educational sector, modified sleep / waking rhythms often exist which are a challenge for pupils and adolescents. Supporting the circadian rhythm enables levels of attention and concentration during work to be increased and error rates reduced.
TRILUX recommendation for classrooms:
8 o‘clock in the morning: sleepy faces throughout the classroom. An increased blue component in the light and modified illuminance levels help to drive away tiredness and stimulate performance capability
TRILUX recommendation for day nurseries:
Young ones have enough energy, but it‘s a calming atmosphere they need. Warm colour temperatures and low illuminance are the tools of choice for minding children through the day.
Avoiding mistakes and achieving occupational safety are particularly important topics in everyday industry. Shift-based work for example leads to an impaired sleep / waking rhythm and prevents necessary recovery. An insufficient lighting level also has its downsides that negatively affect work safety. Human Centric Lighting provides help in such areas.
TRILUX recommendation for production areas:
These systems are the first choice for implementing increased illuminance levels at specific times. Use of acti-vating light enables work tasks to be carried out more effectively and also avoids production losses and is ideally used during the day. As the end of the shift approaches, the dynamic system switches over to more calming light temperatures.
TRILUX recommendation for relaxation rooms:
circadian daylight-synchronous systems
Changing rooms and break rooms are ideal for circadian daylight-synchronous systems, because these support the biological rhythm and can also be used around the clock. Thanks to the improved quality of sleep as a result, this also positively benefits the general state of employee health.
Designing shopping areas is active sales promotion and the right lighting essentially contributes to this. Suitable lighting solutions arouse curiosity, remove threshold fears, increase dwell times and inspire. In short, they lay the foundations for successful selling.
Oktalite recommendation for window displays:
The aim is to direct glances, arouse attention and enhance the impression of quality and value with potential purchasers. This is achieved by using dramatic lighting that exploits changing colour temperatures, intensities and light direction.
Oktalite recommendation for sales spaces:
These create a pleasant transition between the outside and the interior by regulating light intensity and light colour, thereby creating an inviting spatial ambience that increases dwell times.
FROM THEORY TO PRACTICE: TRILUX research projects
User-friendly applications pave the way for people to benefit from the latest findings in lighting research. As a consequence, TRILUX conducts research in the form of various practical projects analysing the opportunities circadian lighting design has to offer.
Important fundamentals were laid in 2006 with the Placar project. Together with the Charité Berlin and other partners, TRILUX is analysing how circadian light influences people. For this purpose, light spectra were defined and generated in brightness, colour rendering and circadian effect. TRILUX designed a lighting system that ergo-nomically distributes light without glare for optimum effectiveness.
OLIVE associative research project
Utilising light for the well-being of people is also the aim of OLIVE, short for „optimised light systems for improving performance capability and health“. OLIVE brings together the visual and non-visual effect of light with intelligent control and implements this into specific applications. The lighting systems adapt light to the ingress of daylight and time of the day and therefore the circadian rhythm. This form of intelligent lighting is controlled via sensors and gestures. TRILUX uses LEDs as the light sources. These enable almost unlimited electronic control options and thanks to their compact dimensions, can be integrated into any applications.
Felix Blatter Hospital project
The Felix Blatter Hospital project is dedicated to the comparability of circadian lighting solutions. The project analyses circadian effects, user-friendliness and procurement and operating costs and is therefore highly useful to lighting designers and construction authorities. As part of the project, rooms on a geriatrics ward were equipped with various circadian lighting systems and these were tested for their photometric properties. A qualitative survey of care personnel concerning user-friendliness supplements the measurements. The results provide comparability that support lighting designers when recommending suitable circadian systems.
TRILUX Active luminaires
With Active luminaires, TRILUX bridges across to the topic of „Human Centric Lighting“ to bring biologically effective light into a wide range of sectors (e.g. health & care, office and education). For example: recessed and surface-mounted luminaires with planar light for patient rooms, offices and classrooms, or surface-mounted luminaires and downlights for traffic paths and social areas.
