Beginning of artificial lightingg g g g

People have always lived and worked in the great outdoors and were continually exposed to natural sunlight, until the great American inventor Thomas Alva Edison p g gproduced a reliable long lasting source of light with electricity in 1879.

In December 1879 Edisons Menlo Park Laboratory in New Jersey, NY was the first complex on our planet which was electrically lighted.

Light: food for our bodiesLight: food for our bodies

Each of our eyes contain about 137 million photoreceptors Thesemillion photoreceptors. These photoreceptions transform light into electrical impulses that are sent to the brain travelling to the visual cortex for the constructions of images, while others travel to the brains hypothalamus and affect our vital functions .

Full spectrum daylight improves our visibility and reading comfort

Reading under full spectrum light causes less strain to the eyesbecause it offers high contrast and reflects colours accurately

John Ott and the apple tree

In the early 1950s Walt Disney asked the well-known photographer d bi l i t J h Ott t k ti l fil f l iand biologist John Ott to make a time lapse film of apples growing

from the bud to the ripe fruit. It was to be used for a film Secrets of life released in 1957.

For time lapse photography it is important that the object does not move. As it was very windy, John Ott decided to put a glass box around the apples he wanted to photograph. After many weeks at the pp p g p yend of filming John Ott was surprised to discover that all other apples on the tree were looking great, had yellow/red colour and were juicy. But the apples he filmed in the glass box were small and looked pale and sicklyand sickly.

This was clear evidence about the importance of UV for the growth of plants because the glass filtered out most of the UV from theplants because the glass filtered out most of the UV from the sunshine. Our modern living today is not very different. We live in homes with Glass windows, work in modern offices with glass windows and drive automobiles with glass windows.

Pros and Cons of UV lightPros and Cons of UV light

Si th i ti f th l t i i d t b lb i 1879 b t ithdSince the invention of the electric incandescent bulb in 1879 we began to withdraw more an more behind the walls and windows and exposed ourselves to artificial light - which differs significantly from natural sunlight.

Looking at our homes, buildings and automobiles today, we discover that our modern life is not much different than the apples of John Ott in the glass box that keep us away from the essential parts of natural daylight which are so important for our well being.

During my travels to different European and North American countries I always discovered that in southern regions with plenty of sunshine we see more happy people with smiling faces -compared to the north with less sunshine.

Pros and Cons of UV lightg

In our modern way of life, our skin is no more used to natural sunshine and the risk of getting sunburn on a vacation in a sunny place is high.sunburn on a vacation in a sunny place is high.

Dr. Jacob Liberman mentions in his book, Light Medicine of the future that for millions of years life evolved under the constant influence of sunlight. People have always felt andrecognised their connection with light. Its effectswere so profoundly obvious to ancient culturesthat they revered the sun as god, blessing itdaily for its gifts.

According to photo biologist Dr. John Ott, there are strong indications that UV light through the eyes stimulates the immune system. There is no question that UV light in large amounts is h f l h i t t it t di t Ott lif ti t i t th t i

harmful; however in trace amounts, it acts according to Ott, as a life supporting nutrient that is highly beneficial.

Pros and Cons of UV light

We should also consider that in the last hundred years, we have polluted our atmosphere to such an extent that it is partly not able to perform a healthy filter function against harmful short waves that are coming down to the surface of our planet.

With the development of artificial full spectrum light, with small traces of UVA , UVB and g , ,having a spectrum, colour temperature and colour rendering close to that of sunlight, we are able to have indoor lighting beneficial forare able to have indoor lighting beneficial for our well being.

Sunlight is composed of variety of energies that are transmittedto our planet in form of electromagnetic waves.

Only a small portion of these waves actually reaches the earthssurface including the UV, the colours of the rainbow from violetto red and the infraredto red and the infrared.

Colour Rendering Index ( CRI )

is a measure of the ability of the light source to reproduce the true colours of objects being lit by the source expressed in percent. So a CRI of 96 means 96 % .

The best possible rendition of colours is specified by a CRI of 100 .The higherthe CRI, the more natural the colours of objects appear.

The CRI is especially important when evaluating fluorescent light sources because they have a wide range of CRI from 65 to 96.For example triphosphor fluorescent lamps have a CRI of around 85For example triphosphor fluorescent lamps have a CRI of around 85.

Instantdaylite fullspectrum fluorescent lamps have a CRI of 96 and higher.

Colour temperature ( Kelvin )

This refers to the colour appearance of the light.

The colour temperature of lamps creates the mood of the space around and canThe colour temperature of lamps creates the mood of the space around and can influence the viewing of colours of various objects and work performance.This apparent colour of light source is measured in Kelvin (K).

Natural daylight has 5800 Kelvin being a blue/white light .A low colour temperature corresponds to warm or red yellow appearance like incandescent lamps at 2800 Kelvin or candle light at 1850 Kelvinlike incandescent lamps at 2800 Kelvin or candle light at 1850 Kelvin.

History of Instantdaylite

The technology of full spectrum tubes is not new in itself. The US government commissioned gy p gthe development of fluorescent tubes for nuclear powered submarines and power stations where people spend months underground with no exposure to natural sunlight. Although the results back in the 90s were inadequate it was better than nothing and simulated circadianresults back in the 90s were inadequate it was better than nothing and simulated circadian cycles which helped people over these long periods. Since then the quality of the tubes has improved, but no specific luminaires for them were on the market.

In a collaboration between my partner Mrs. Eva Binder - who has a medical background through research conducted by her deceased husband Univ Prof Dr Dieter Binder professorthrough research conducted by her deceased husband, Univ.Prof.Dr.Dieter Binder, professor of organic chemistry at the University of Vienna, Univ.Prof. Dr .Bernd Saletu - as head of the sleep laboratory at the Central Hospital in Vienna together with his wife Dr. Gerda Saletu -and myself - as founder and owner of a company producing special lights for exhibitions and Museums we succeeded to developed such specific luminaires under the brand name of Instantdaylite and to start production in 2009.

Conclusion

The biological reactions triggered by natural or artificial sunlight start between 1700 and 2000 LUX at eye level. 20% of the light absorbed by the eyes is used for viewing. 80% of this light goes right into the hypothalamus as control center for the autonomous nervous system and the circadian cycles. When you consider that natural sunlight at noon in summer y y greaches > 80.000 LUX at eye level you understand the need for an adequate illumination which is certainly not reached with the 500 LUX as prescribed by the German building code.

Together with a renowned lighting manufacturer with their own 5000 sqf. laboratory we succeeded to develop a luminaire which solves the challenges of heat dissipation, glare, tunable colour temperature electromagnetic compatibility and sufficient brightness to createtunable colour temperature, electromagnetic compatibility and sufficient brightness to create an almost natural environment: Instantdaylite.
