This paper reviews developments in hybrid light guidance systems.

In these daylight and electric light are simultaneously delivered into a building where they are combined and distributed via luminaires. The technology used in hybrid systems, both conceptual and realised, is discussed. The review speculates as to their likely performance in terms of daylight delivery; capital and running costs; user reaction to the systems; potential impact of the systems on the building which they light; and suitable design methods. It is noted that a substantial amount of work remains before the potential of hybrid systems may be realised, notably on their long-term economics and feasibility in different geographic locations.

Light brings our environment to life. In interior design, it is an independent element, also referred to as the fourth dimension of a room. DOMUS stands for much more than simple lighting. DOMUS lamps have a distinctive quality – their light is pleasantly and soothing – they combine perfect function with the concept of man as the measure of all things.

DOMUS lamps have a great variety of forms and you’ll be surprised by the atmosphere they can create. Discover light as an element of interior design, for living and dreaming.

Inspired by DOMUS, VIVA-LITE has created one of the first full-spectrum based warmwhite energy-saving lamps with a CRI of well over 90 Ra. That means that even for a warmwhite ESL lamp, the colour reproduction is extremely high, thus making DOMUS lights look even nicer when lighted with VIVA-LITE lamps.

Therefore you now have a choice – wether it be fullspectrum daylight lamps or fullspectrum warmwhite lamps – VIVA-LITE and DOMUS make a perfect couple for any living or working environment. Be sure to check out this new set of lamps and lighting options.

About the Housing Fair:

The ca. 40 fair houses built on the verdant housing fair area in Valkeakoski form a multi-faceted combination. An extensible, unique house for a first home, a TV-house and a passive house with a vivid design are good examples of the extensive selection of houses. The fair includes houses built in both traditional and modern styles, one- and two-storey solutions, stone and wood houses – not to mention the latest trends and experimental building.

In Seinäjoki, Finland, there was a Jämerä-Stonehouse (made of aircrate) showing on 21.2.2009. What made that occasion very special, was the lighting of the house: the whole house was lighted with Viva-Lite fullspectrum daylight lamps, both compact fluorescent lamps (CFL) and fluorescent tubes (FSL).

There is plenty of good light in the house which is very important because the family has children. Children need a lot of daylight to be able to develop in a good way. The lighting was carried out mostly indirectly by Viva-Lite fullspectrum lamps and tubes. The family is very satisfied with this lighting.

Results are so good that other schools are getting interested in lighting in schools, says Arne Lowden. a researcher in a stress research institute in the Stockholm University.

In the darkest wintertime in two classrooms regular yellowish fluorescent lamps were changed to so called full spectrum fluorescent lamps. The classrooms were the students homeclassrooms so they had almost all their lessons there.

During the weeks of research was e.g. the melatonin level that controls sleep, measured. The levels become lower and the students were more alert. In the evening were the students more tired. When sleeping they didn´t move as much as earlier because their sleep was more effective.

Their classroom was perhaps a little darker than the average before the change of the lamps, but results show anyway that good lighting is essential for all students. More alert students can easier cope with school work, says Arne Lowden.
Students might need to ”fill” themselves with light in the morning when people are most sensitive to light. School often starts at 8 am and students often miss the important morning light.

Pupils in secondary school are not much outside during breaks either and during weekends they might sleep too long in the morning so they´ll miss a lot of light.

It´s not only young people who need good light. Bad light can make personal tired in every job has been realized more and more often in Sweden, Arne Lowden notices.

Johan Bergman notices the difference between his new and old classroom.
– In the old classroom was I often so tired during the lessons that I almost fell asleep. Here it´s totally different.
The difference can best be noticed when pupils move from classroom to another:
– The other classrooms feel so dark and depressive especially in the winter when it´s dark outside, says Elin Försborgen.

Arne Lowden. gets more and more inquiries from workplaces, especially those with rooms without windows.
– Our next project is Forsmark power plant with rooms without windows. The goal is to increase alertness in daytime
Even private persons are interested in lighting. Light therapy lamps for private use sell well, says Arne Lowden. who himself has one on his writing desk. There he sits in the morning and feels that bright light makes him more alert. He recommends light therapy lights especially for shift-workers. So far it is not sure if it helps against depression, established SBU, an institute that evaluates health care technologies in Sweden, last year. (AD-Lux: this is wrong information. There are lot of studies, which shows that light therapy helps against depression).

We need more research on this area. The indoor light is of more and more importance in our lives. In investigations we can see how sleeping difficulties and fatigue have become more common, and that is something we can fight with right kind of light, says Arne Lowden.

Researchers in Australia have reported that children need to spend at least two to three hours a day outside in direct sunlight to avoid becoming short-sighted.

The results of the study from the Australia Research Council found that exposure to bright light can help regulate the growth of the eyeball during childhood, significantly lowering the risk of myopia.

Carried out by researchers at the Australian National University and Sydney University, the study compared the eyesight of Chinese Australian and Singaporean children and discovered that 30% of children in Singapore needed spectacles compared to 3% of Chinese Australians.

Both groups spent the same amount of time watching television, playing computer games and reading, but whilst children in Singapore spent on average 30 minutes a day outside those in Australia spent around two hours.

Professor Ian Morgan, lead researcher on the study, commented: “We’re seeing large increases in myopia among children in urban societies all around the world – and the outstanding common factor may be less and less time spent outdoors.

“Humans are naturally slightly long-sighted. We see that in rural populations all round the world. But when you start intensive schooling, and spend little or no time outdoors, you get this dramatic rise in myopia. In some East Asian cities 80-90% of children are affected – and governments and the World Health Organisation are very worried out it.”

The Sydney Myopia Study was funded by the National Health and Medical Research Council.
