OFFICE

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.

OFFICE

LIGHTING QUALITY STANDARD

Besides the legal standards, there are also other parame-ters which are no less impor-tant and affect the quality of the lighting solution of the whole office building.

Therefore, for OFFICE appli-cations, we place a strong emphasis on the LQS criteria that are most able to support the provision of a high quality lighting solution.

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

Because we spend more than half of our productive life at work, a modern office must provide lighting conditions that enable comfortable performance of tasks as well as supporting creativity and inspiration.

OFFICE

ERGONOMICSPHYSIOLOGICAL FACTOR

Human performance fluctua-tes according to the circadian rhythm and the production and levels of certain hormo-nes. Light can be used to sup-port, modify and regulate this natural rhythm in order to im-prove performance through the day.

OFFICE

ERGONOMICSGLARE PREVENTION

Excessive glare causes fatigue, visual impairment that can lead to reduced concentration and make the text visibility on-screen more difficult.

At the office desk, a work-friendly UGR of ≤ 19 is a fundamental requirement.

OFFICE

EMOTIONWhen a lighting designer creates a lighting solution, their goal is to meet visual needs as well as to create a space where employees feel conformable and happy.

OFFICE

EMOTIONILLUMINATION OF ROOMS SURFACE

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.

EMOTIONDYNAMIC LIGHTING

The right light can greatly im-prove working conditions by influencing the production and regulation of several key hormones to help improve working efficiency.

EFFICIENCYPRESENCE DETECTOR

An extraordinary effective method by which to increa-se the efficiency of a lighting system and optimise energy consumption.

This is especially in the case of office lighting, where many spaces do not need to be con-stantly illuminated.

OFFICE

EFFICIENCYDAYLIGHT SENSOR

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.

OFFICE

EFFICIENCYLIGHTING SCENE

The use of lighting scenes than can be manually selected or regulated by timers and calendars, means that various lighting parameters (intensity, CCT, colour) can be set according to activity, time, need and comfort.
