Illuminance ranges for Indoor Activities/Areas

Image
The illuminance recommended for a specific type of activity will depend partly on the nature of that activity(principally its visual difficulty) and partly on the design of the interior concerned (particularly the lightness of the surroundings). The table below gives recommended illuminance , based on the scale defined above, for different areas and activities. The values given are average maintained illuminance over the task area. There fore the illuminance may not fall below these values, no matter what the age of the installation. The values are valid for normal visual conditions and take into account the following factors: - requirements for visual tasks -safety -psycho-physiological aspects such as visual comfort and well being -economy -practical experience The illuminance should be increased, when: -unusually low reflectances and /or contrasts are present for the task -visual work is critical -errors are costly to rectify -accuracy or higher productivity is of ...

Factors Influencing the Lighting Design

Image
Lighting is an Art as well  as a Science. There is no ideal or optimum solution to a particular lighting problem. The design process should be seen as consisting of two quite distinct phases. Phase one begins with the client, and involves studying the various local factors that will influence the design. Phase two is the design process proper, and it is here that the first of many design decisions are made. Factors Influencing the Design It is very important that the lighting designer establishes a very good working relationship with the client and with all the others engaged in the project ( such as architects, interior designers, air conditioning engineers) at the earliest possible stage in its development. It will then often be possible to influence basic design conditions concerning the space to be lighted. Later on it might well be too late to make those changes that would have simplified or improved the final lighting design. The most important factors dictated by the...
