Inspired by the sun, we bring daylight into the building. Human Centric Lighting


Light that serves the human being.

Human Centric Lighting lays the focus on the impact of light on human well-being and health. The spectral composition of the artificial light, expressed as the most similar colour temperature, as well as its temporal change are modelled after the course of natural daylight and replicate it to the greatest extent possible. These parameters are decisive when it comes to whether or not the light has an activating or relaxing impact on the human organism. Light is knowingly affecting our “inner clock”. A lighting that is modelled after natural daylight supports the natural biorhythm of humans around the clock: It makes a human being feel well, potent, and able to sleep better.

Light that adjusts to the human biorhythm

Responsible for the biorhythm of human beings is their hormo- nal balance, particularly that of melatonin, which is responsible for our wake and sleep patterns. The share of blue in daylight controls the melatonin level in the human body via receptors in the eye, and thereby the ability to concentrate. It also affects the alertness and the readiness to sleep. If the artificial light adjusts to the natural human biorhythm via the control of the colour temperatures, among other things, our ability to concentrate and our performance can be increased significantly.

studies* show that, for example, the rates of mistakes at schools were reduced by up to 45 % while the speed of work increases by approx. 30 %. Even at workplaces, employee‘s level of performance increased by almost 20 %, in addition to a higher motivation level.

Prerequisites for health light

In order to successfully realise Human Centric Lighting projects and to design illumination that is biologically effective, three require- ments are of central importance:

  • The lighting system allows for a colour temperature of the artificial light that corresponds as closely as possible to that of natural daylight.
  • The lighting automatically changes with respect to light colour and level of brightness, and does, as such, replicate the natural course of daylight – or fulfils other, specific target requirements in the sense of a biological effectiveness („inner clock“).
  • The lighting in the room and within the field of vision of the human being is distributed in such a way that it complies with both, the physiological requirements of the visual task (and therewith also with the requirements posed by standards), as well as taking into consideration the directionality of the photo receptors in the human eye.

Human Centric Lighting
Applications

ProductionLight in the industry – ideal daylight around the clock


At the machine or at assembly: if a biologically effective lighting systemprovides for light at the workplace, employees in the industry are more alert and more focused. They can sleep better at night and are more rested during the day. This lowers the error rate and increases safety and security.

Functions
Manual light control via wall push-button:
- On/Off
- Dimming
- Colour temperature

OfficeLight at the office – in compliance with your inner clock


People in the industrialised world spend a large portion of the day in closed buildings. Modern light systems bring the daylight and its natural course into the office. The result: increased well-being, the ability to better concentrate, and healthier workplaces for tomorrow.

Functions
- Automatic time-dependent control of the colour temperature
- Daylight-dependent regulation and presence-dependent switching

Manual light control via wall push-button:
- On/Off
- Dimming
- Colour temperature

ClassroomLight in the classroom – Creating optimal learning conditions


hose who learn need good light to see. Studies prove that a biologically effective illumination has a positive impact on the learning behaviour and helps students to work more attentively and more focused.

Functions
- Automatic time-dependent control of the colour temperature
- Daylight-dependent regulation and presence-dependent switching

Manual light control via wall push-buttons:
- On/Off
- Dimming
- Colour temperature

Geriatric careLight in clinic and care-giving, increasing well-being


Healthy light is a blissful relief (not only) for sick people. An illumination that is adjusted to the course of the daylight supports the circadian rhythm, the emotional experience and the recovery of patients. In care-giving, too, a circadianally effective illumination sustainably supports the well-being of seniors and people suffering from dementia: the light activates during the day and promotes sleep at night. At the same time, optimal light conditions ease the work of the nursing staff.

Functions
- Automatic time-dependent control of the colour temperature
- Daylight-dependent regulation and presence-dependent switching

Manual light control via wall push-button:
- On/Off
- Dimming
- Colour temperature

Human Centric Lighting Realising light applications cost-efficiently and goal-orientedly Most straight-forward entry into

Human Centric Lighting is the light of the future. And this future has already started today: OEM Systems Group is offering an complete system for a straight-forward and efficient entry into MixedWhite applications – from ECG via LED modules all the way to the Touchpa- nel for easy-to-use control.

MixedWhite basic

Manual system for circadian applications

The MixedWhite basic system includes the ECG, controller and LED modules with highly efficient warm-white and cold-white LEDs. The overall solution enables the realisation of white/white light controls for a manual operation via commercial push-buttons. The core element of this system is the MixedWhite basic controller. It provides the option to adjust the brightness and colour temperature of the lighting system individually via wall push-buttons. The two DALI interfaces of the controller enable the connection of dimmable electronic gear units for the operation of LED modules with cold-white and warm-white LEDs. A particular advantage is provided by the combination of the ZITARES intelligent ECG with two independently controllable output channels.

MixedWhite plus

Automatic systems with real-time clock for circadian light applications

MixedWhite plus is building upon the convincing pro- perties of MixedWhite basic. This solution additionally includes a real-time clock which allows for the auto- matic progression of daylight-dependent characteristics with a change of the colour temperature – corresponding to the circadian rhythm. In combination with a sensor, additional energy savings can be achieved thanks to the daylight-dependent regulation and presence detection. Controlling this system is conveniently possible via push-button or Touchpanel.
