this means an easy integration in complex

systems or to create more challenging

luminaries

good colour rendering are possible

This means easily adaptable light

LED Technology

Coloured light is possible,

this means changeable light colours are available!

Losses of Light and Energy

caused by filters are avoidable


Porto, 30. 01. 2014



LED are dimmable and

quick switchable

that means the light can be easily adjusted

LED as an electronic device

makes new dynamic light solutions possible, which are unknown until today

LED pros; How to use them?

Combing the change of

light distribution,

colour temperature and

the intensity.

LED pros; How to use them?

Combing the change of

light distribution by using

different lenses and reflectors,

colour temperature by

using different LED in one Luminaire and influencing the

intensity by dimming

Efficacy would mean:

As dynamik as possible!

People would ask:

How much change is appropriate?

Regarding perception constanty and the feeling of

security, etc!

What is plesant and acceptable? What makes sense?


Porto, 30. 01. 2014



LED Pro: More exact light distribution

Design advantages:

Light, where it is needed

Pros: less light tresspass, less light scatter

Cons: high contrasts, harsh shadows, direct glare seems to be

stronger

Porto, 30. 01. 2014



Lit and not lit, exactly divided

Porto, 30. 01. 2014



Scattered light combined with lit focus points allows a good orientation, which helps to feel secure, knowing: Where am I going?

Differentiation in intensity and illuminated focus points

Many small light sources provide many challenges, combine the possibilities

Porto, 30. 01. 2014

Porto, 30. 01. 2014



Many LED in one luminare provide many possibilities

If you do not use all LED in one time, it will

be possible to

create different light situations with one

luminaire:

for example:

LED with differnet lenses or refractors

(wide or narrow light distrubution)

LED with different colour temperatures to

have other light in the evening the in the

morning)

The new possibilities Orientation, Attraction, Identity, Energy, Wellbeing offered by the use of LED lighting.

To control the light will allow to implement differentiated, changing light also in public space.

After a careful analysis of the urban spatial situation and the lighting requirements in different situations of use scripts are written for a light scene in a public space.

There are parameters to be assigned, that allow an automatic adjustment to the changing situations.

In future it will be possible to integrate more Functions in on luminaire, this will give the chance to to adapt the light to: - different situations of use - different times of the day or the year - different climatic conditions! LED technology will make it possible to to adjust the light more exact to the constant architectonical, but also to changing behavioural situation.

LED-technology will be flexible also for future situations, because of the control systems!
