personal light – dynamic lighting for activity and well-being

Think, read, create, rest. Pick your own light! The height of our chairs, the size of the screen text and surgery, for instance, a colder light level may not create the the volume on our phones, we are increasing accustomed peaceful ambience we crave. to being able to adjust and select our preferred settings   Our preferences for light can also differ with age; the in our working lives. It’s only really the lighting which we young are inclined towards a colder light while as we get don’t adapt to our personal preference – and that’s about older this changes to warm. Tunable White is a new...

From the small to the large – the technique is simple Technically, it’s not that complicated. Everything is controlled with a DALI Device Type 8 and can be implemented with different types of control units depending on what you want to achieve. If you want to imitate daylight in colour and intensity automatically, use a router system, otherwise it is often enough with a generic control panel, simple button panels or touch panels to control manually.

Better light in the conference room Conference rooms are often located in the middle of the building without access to daylight. It is an area where the colour temperature control can be used in several ways.   A cooler light when more active tasks are being performed, or a warmer light when we need to focus. A common issue when using video conferences is that camera is unable to handle the light levels as well as the human eye, so we are perceived as looking more sickly. With a Tunable White solution, we can adapt the light level so that the faces of the participants are rendered as...

All light on me – the auditorium Education or full-day conference? As well as having scenes with different lighting levels, it is advisable to also control the colour temperature. By using a timing control the colour of the light provides the participants with an idea of the time of day. Alternatively, we can use the colour temperature to create different scenes. Refreshing high levels of cold light for activity or warmer dimmed light for focus and concentration. The light on the presenting area is controlled separately depending on what activities are going on there.

Welcoming in the entrance or waiting room In the entrance or the waiting room light is controlled with a router solution to imitate daylight, both in intensity and colour. This can be especially important if there is no natural daylight reaching in the room. This solution provides a sense of having access to daylight, even if the room is located in the middle of the building where there is limited access to the real thing. Pozzo creates a feeling of natural light wells, reinforced by adding light on the walls with Pleiad Wallwasher G3.

Personal light in the cellular office A cellular office is the easiest room to apply a Tunable White solution as there is only one user who controls the light according to his or her preferences. Think of a cold, intense light when you want to activate yourself or a warm dimmed light for conversations, reading and tasks which require concentration. Using a suspended direct/indirect Combilume, supplemented with Pleiad Wallwasher G3, provides the ambient and task light requirements, with the colour temperature and intensity controlled via a simple panel on the wall.

Activity or rest in the pause room In breakout rooms the benefits of colour temperature control are in their element, transforming how you can use the space. A pause in the cold light revitalises us while a warmer light calms us down. In this example we have chosen recessed Pozzo. The large, wide beam distribution creates a light-well effect, giving an impression of natural light, further optimised with a varying colour temperature which imitates the evolution of daylight throughout the day. Because the ones who pauses also want control a simple panel on the wall can be used to define a...

Dynamic in the open plan office Open plan offices cannot be controlled to reflect each individual’s personal preferences since the room is lit for a group of people. Here we recommend a router solution that varies the light over time and adjusts the colour temperature mimicking the light outdoors. In the ceiling we have Multilume Flat and, to strengthen the sense of a natural daylight, the walls are lit using Pleiad Wallwasher G3.

How does it work technically? The LED modules contains a mixture of diodes providing warm or cold light. By mixing the light from these we can get colour temperatures between 2700–6500 kelvin out of a single luminaire. Everything is controlled via DALI Device Type 8 and can be managed with different types of control units depending on what you want. The simpler panels have buttons or levers where the colour temperature is controlled with a slider and the intensity with another.   For an automatic dynamic control of colour and intensity a router system that dictates the levels over time is...

Is it good for humans? Up until now, our understanding has outstripped the technically capabilities, with various research projects being conducted within this field. The fact that blue light activate and warm light calms, in increasing substantiated, it is all about imitating the natural light and its variation that has controlled our biological clock since the origin of life. With dynamic light we can see that the biological clock keeps time, especially during the dark months, or in rooms with limited access to natural light.   The biological clock, also called the circadian rhythm (from...

DALI Device Type 8 DALI ballasts that are compatible with DALI Device Type 8 provide functionality for controlling colour temperature. DALI ballasts that are compatible with DALI Device Type 8 are controlled with only one DALI address that controls both the cold and the hot diodes. The function with different colour temperatures requires no programming with respect to the mixture of cold and warm light since the logic is built into the devices. The desired colour temperatures for different scenes are set Conversely, when using DALI ballast which do not com- municate according to DALI...
