TunableWhite, lighting psychology & wellbeing Innovative and stylish luminaire CLEARANCE brings wellbeing to offices, meeting rooms and classrooms
We need daylight for a wide range of reasons yet spend most of our waking time indoors under artificial light rather than outside in the sun. Until recently, the artificial lighting we have come to depend on was used only to provide sufficient illumination to facilitate visual performance and not to supply us with any of the beneficial properties of daylight. However, as our understanding of light’s effects on human wellbeing has grown, it has become very apparent that provision of a sufficient illumination level is simply not enough to support our comfort, performance and long-term health. General illumination needs to do more! The lighting parameters of daylight are different to artificial light in many ways, most notably in that they are not monotonous. The brightness and colour temperature of daylight continually change according to the time of day, season and even the movement of clouds. Furthermore, the distribution of daylight is much softer and more homogenous. These are all properties that we now have the technological capability to incorporate into modern and innovative artificial lighting, helping us to bring outdoor wellbeing into indoor environments.
TunableWhite, lighting psychology & wellbeing Colour temperature and TunableWhite Most of the light we perceive is what we call white light. This includes the bright sunny light of a summer’s day, the cosy glow from a candle’s flame and the lighting we use indoors for general illumination. However, all of these lights are very different, and a fundamental part of that difference lay in their Correlated Colour Temperature (CCT). CCT refers to the shade of white compared to a black body and is expressed in Kelvins [K]. Simply put, CCT is a measure of how warm or cool light appears as it shifts from lower, redder colour temperatures to higher, bluer colour temperatures. Take as a comparison the warm 2700 K of an incandescent bulb, the neutral 4000 K of the fluorescent tubes most commonly used for office and classroom lighting, and the cool 6500+ K of daylight. They are all white light, but they look and feel very different. Colour temperature has a profound effect on our mood and behaviour. Warmer light is relaxing and helps create a tranquil, safe and more intimate atmosphere. On the other hand, cooler light is energising, improves concentration and makes a space feel more open and lively. By altering the CCT of the light provided in a space, it is possible to improve work performance, increase alertness and safety, support relaxation and promote the psychological comfort and wellbeing of individuals. TunableWhite is a modern technology that allows for the CCT of the white light emitted by a luminaire to be adjusted according to various principles or simply according to desire. For example, TunableWhite can be used to mimic the natural CCT changes of daylight or to support a set cycle of activity by promoting concentration and relaxation at appropriate times.
TunableWhite, lighting psychology & wellbeing Dimming Dimming is not new in the lighting world, having been available in various forms for many years. However, it is only during the last few years that we have come to appreciate some of its many benefits including its use mimic the natural brightness changes of daylight to aid in performance and relaxation. What’s more, not everyone feels comfortable under the same brightness, with some preferring softer light while others, most notably older people with aged eyes, need brighter light. Giving people the option of choosing a level of illumination that suits them contributes to visual comfort and feelings of psychological wellbeing.
Light distribution Our bodies have adapted to the light distribution of daylight, which seems to come towards us from all angles to softly and evenly illuminated every corner. In contrast, direct artificial lighting is designed to illuminate horizontal surfaces and facilitate the performance of work tasks. Such light does not sufficiently illuminate walls and ceilings and results in the ‘cave effect’, where the upper area of a room becomes dark and heavy. This makes the space feel smaller and maybe claustrophobic and even oppressive. Such an environment can easily create feelings of demotivation and fatigue, and over time possibly result in more significant psychological discomfort. In answer to this issue, the lighting industry now offers luminaires that incorporate indirect light distribution where a portion of the emitted light is directed towards ceilings and walls and then diffusely reflected back into the space. This results in a softer, more homogenous illumination characterised by pale shadows and the elimination of the dark corners associated with the cave effect. Studies have show that people prefer the combination of visually enabling direct illumination and psychologically comfortable and natural feeling indirect illumination.
TunableWhite, lighting psychology & wellbeing Clearance CLEARANCE is a stylish and innovative luminaire with a slimline profile and transparent optical part that affords it an almost weightless presence, making it an ideal addition to any area designed with an aesthetic emphasis. More importantly, however, CLEARANCE implements all the latest knowledge about the effects of light on human wellbeing. Thanks to the use of revolutionary LED edge-lighting technology, light is projected across a transparent planar surface that allows for both direct and indirect distribution. The result is low-glare, soft and homogenous yet high quality illumination that ensures visual comfort and performance as well as creating a psychologically pleasant atmosphere. Using the industry standard DALI protocol, the luminaire also facilitates full dimming and TunableWhite functionality with an office and classroom friendly neutral CCT range of 3000–4000 K. CLEARANCE is a perfect combination of style, technological innovation and understanding of and respect for human wellbeing in visually and mentally demanding areas such as offices, meeting rooms and classrooms.
