HUMAN CENTRIC LIGHTING (HCL)

SIMULATION OF DAYLIGHT

The characteristics of the HCL illumination consider more than just vision. The focus is on the person. Human Centric Lighting stimulates the well-being and supports stable health of the person.

The focus is on the person, also regarding to illumination. A contemporary lighting system must be able to enhance the well-being of the person more than ever before. Knowing that the human organism has been and will be characterised by daylight, the objective must be integrating the positive aspects of daylight into modern light planning. It was not without reason, that the issue of daylight was included in the revision of the European standard EN 12464-1 „Illumination for workplaces in interior rooms“. But what should be done, if sufficient daylight is not available? In this case, artificial light can assume specific daylight functions and provides „the right light at the right time“. Based on the natural light, the artificial light is given a dynamic structure in the course of the day. Thereby, the changes in the level of illumination and in the light colour are of particular importance. Such lighting is able to support the circadian rhythm of the person.

Our cells and organs and thus the body‘s functions are linked to this rhythm, with the human body clock being the pulse generator. It controls sleep and waking phases, but also heart beate, blood pressure and mood. This cyclic process is also characterised by the fact that all biochemical functions have individual high and low points in the course of the day. The circadian rhythm is regularly synchronised with the outside world whereby humans are primarily influenced by the brightness of the day and the darkness of the night.

APPLICATION AREAS

Optimal use of potentials

The natural daylight changes constantly from morning to evening, both in brightness and colour as well as direction. A professional lighting system can imitate this rhythm. It provides interior rooms with biologically effective artifi cial daylight or supports the natural light there. Human Centric Lighting can support in particular lighting tasks in the offi ce, care, industry, shop and education sectors.

Planning practice

Many useful hints for planning and precise application are found in DIN SPEC 67600 : 2013 04. Often only the classic illumination level on the workstation is crucial for planning, but also the spectral distribution and the illumination level at the eye.
