EDUCATION

We believe that a high quality lighting solution is about more than meeting standards. For this reason, we developed the Lighting Quality Standard (LQS), which focuses on the provision of optimal illumination that ensures the comfort and wellbeing of users.

The LQS is a unique assessment methodology based on 20 objectively quantifiable criteria that enables the clear evaluation of a lighting solution's quality.

EDUCATION

LIGHTING QUALITY STANDARD

Optimised classroom lighting improves student concentra-tion and performance.

Therefore, in EDUCATION ap-plications, we strongly em-phasise those criteria within the LQS that support the pro-vision of a high quality solu-tion for classrooms. EMOTIONERGONOMICS

ERGONOMICSErgonomics is all about providing the right light in the right place at the right time.

80 % of our perception of the world around is us visual. In education, this makes it especially important the lighting supports accurate and comfortable visual perception.

EDUCATION

ERGONOMICSPHYSIOLOGICAL FACTOR

Clear perception of learning materials has a direct influen-ce on students' relationship to learning, with the use of physiologically effective illu-mination playing a key role.

EDUCATION

ERGONOMICSGLARE PREVENTION

Excessive direct and indirect glare causes fatigue and reduces concentration.

At the desk, glare should be reduced to UGR of ≤ 19.

ERGONOMICS

EDUCATION

HARMONIOUS DISTRIBUTION OF BRIGHTNESS

Extensive research into the effects of light upon perception and wellbeing have led us to the conclusion that meeting normative standards is a minimum and that more emphasis should be placed on the uniform distribution of brightness throughout a classroom. Standard

Right Light

EMOTIONLight has a powerful ability to influence mood in a positive or negative way. An understanding of this is fundamental in the creation of a successful lighting solution.

EDUCATION

EMOTIONILLUMINATION OF ROOM SURFACES

The use of an optimal ratio between the illumination of all room surfaces aids in the prevention of both visual and psychological fatigue.

This includes paying attention to the illumination of vertical as well as horizontal surfaces.

EDUCATION

EMOTIONDYNAMIC LIGHTING

Dynamic lighting that allows for the modification of the intensity and colour temperature of the light is highly beneficial for the visual, psychological and physiological wellbeing of students.

It can be used to support the functioning of the circadian rhythm as well as improve alertness, performance and calm restless behaviour.

EDUCATION

WARMCOLD

EMOTIONEMOTIONAL LIGHTING

Emotional lighting is stren-gthened by the use of lighting scenes that can be changed to create a particular atmosphe-re, such relaxing, motivational or productive.

EDUCATION

EFFICIENCYThe task of modern lighting technologies is to bring incre-ased comfort and control to users.

In schools, which use exten-sive lighting systems, it is also important to maximise ener-gy and cost savings by ensu-ring the used technologies are also highly efficient end effective.

EDUCATION

EFFICIENCYPRESENCE DETECTOR

In schools, there are many spaces that do not need to be illuminated all the time.

By incorporating presence de-tection into the control sys-tem it is possible to benefit from great savings.

EDUCATION

EFFICIENCYCONSTANT ILLUMINATION SENSOR

Constant illuminance sensors ensure that the required lighting conditions are delivered over the full lifetime of the lighting system, regardless of inevitable dirtying and degradation of the luminaires.

Using these sensors can bring energy savings of up to 20 % during the first few years of a lighting system's operation.

Daylight sensors enable the lighting to adapt to the amount of daylight available, no matter what the time, weather or season.

As levels of natural daylight fluctuate, artificial lighting is used to ensure the required level of illumination.
