1. AdequateilluminanceThe performance of the human eye largely depends on the level of

illuminance in the visual field.

As illuminance increases, motivation and overall performance are

also enhanced, while the tendency to make mistakes declines.

Rothschild,Dubai

10 Rules for good lighting


2. Harmoniousdistributionofluminance

A balanced distribution of luminance on the various surfaces makes

an interior visually interesting.

Inadequate or excessive contrast, on the other hand, causes visual

strain and fatigue..

3. AdequateglarecontrolGlare in an interior is rarely so severe that visual performance is

significantly reduced, but it can be irritating and cause eye strain.

Highschoolforhealth,Celje,SlovenijaHighschoolforhealth,Celje,Slovenija



4. Goodcontrastrendition

Contrast is necessary for the human eye to be able to discriminate

between objects and their background.

A lighting system with good contrast rendition does not cause

reflected glare even on shiny surfaces and documents, so that

text is easy to read even on glossy paper.

NoorIslamicBank,Dubai

5. TherightdirectionofincidenceThe direction of incidence of light is important for Contrast

Rendition, as it determines the angle at which any reflections can

be seen.

It influences the distribution of light and shadow, which is the key to

threedimensional vision on the one hand, and can be irritating

or even dangerous in the case of heavy shadows, on the other.

Atlantis,Ljubljana



6. Pleasantshadowconditions

Shadows reinforce threedimensional vision and facilitate

orientation. Good shadow conditions are the product of an

effective combination of diffuse light and directed light.

7. Suitablecolor

appearance

In the course of the day the light appearance of natural daylightchanges. Artificial light can also be produced with different lightappearances or colors so as to support various lighting functionsand moods.

Arki,Dubai



8. Naturalcolorrendition

Only the spectral colors that are contained in the incident light can

be reflected by an object and perceived by the human eye.

Color Rendition is a measure of the ability of an artificial light source

to show the natural colors of an object.

Volksbank,Ljubljana

9. EffectivelightingatmosphereLight affects our mood and feeling of wellbeing. The result is a

subjective, more or less unconscious impression of an interior

and its light. This aspect of good lighting planning also requires a

degree of experience with the interplay of the various factors

and a fine feeling for good light.

Mediahouse,Stavanger,Norway


positivelightingatmospherefortheworking environment


10. Efficientenergyconsumption

A basic requirement for modern lighting planning is the careful and

economical use of energy. The various solutions now available

relate not only to new installations, however, but also to

retrofitting and refurbishing old and inefficient systems.
