Good light is needed to create optimum visualconditions indoors. When planning a lighting

installation a number of factors have to be taken intoconsideration which interact to determine the qualityof the system as a whole. DIAL has listed these factorsas Ten Guidelines for Right Light . This is a useful

source of information for creating lighting solutionsthat meet the needs of the user to the full andprovide efficient working conditions.

General Information



Guidelines for Right Light 1. Adequate illuminance

2. Harmonious distribution of luminance

3. Adequate glare control

4. Good contrast rendition

5. The right direction of incidence

6. Pleasant shadow conditions

7. Suitable color appearance

8. Natural color rendition

9. Effective lighting atmosphere

10. Efficient energy consumption



Design a general lighting scheme of an office using DIALux

Room SpecificationsRoom dimensions

Width 3.0 m Length 5.5 m Height 2.5 m Working Plane Height 0.760 m Reflections

Ceiling 0.70 Walls 0.50 Floor 0.20 Required illuminance levelGeneral lighting 500 lux on working plane

Luminaire SpecificationsLuminaire type TBS600/135 C7-60 Lamp type TL5 18W Project Maintenance Factor 0.80



Standard Lux Level Requirement



Recommended Surface Reflectance

Surface Reflectance

Ceiling 7 or above

Walls 0.5 – 0.7

Partitions or screens 0.4 – 0.7

Floors 0.1 – 0.3

Furniture and equipment 0.2 – 0.5

Window shades 0.3 – 0.6



Step for Lighting DesignCreate a new project

Enter the dimensions of the room

Enter the reflectance factors of the ceiling, walls, and

floors according to the table.Insert a luminaire from a data base inside the luminaireselection toolbar.

Insert the luminaire to the room using a fieldarrangement or any.From the luminaire data choose mounting and put theright lux that you need then press suggestions.

Choose start calculation from the output toolbar.
