What is BS EN 12665-Lightning requirements about?

BS EN 12665 discusses light and lighting. Lighting is a major end-use of energy in most areas. Design strategies that reduce electric lighting requirements should thereby reduce annual electrical consumption and peak electrical loads.

BS EN 12665 defines basic terms and definitions for use in all lighting applications. BS EN 12665 also sets out a framework for the specification of lighting requirements, giving details of aspects that are to be considered when setting those requirements

Who is BS EN 12665-Lightning requirements for?

BS EN 12665 on light and lighting is useful for:

Light Manufacturers
Design engineers
Quality control personnel

Why should you use BS EN 12665-Lightning requirements?

The lighting requirements for space are determined by the need to provide adequate illumination for safety and movement, conditions that will facilitate visual performance and colour perception, and acceptable visual comfort for the occupants in the space.

The relative importance of these factors will vary for different applications. This basic framework covers aspects in the field of vision, photometry, and colorimetry, involving natural and man-made optical radiation over the UV, the visible and the IR regions of the spectrum, and application subjects covering all usages of light, indoors and outdoors, including environmental, energy, and sustainability requirements and aesthetics and non-image-forming biological aspects.

BS EN 12665 guides you to a basic framework intended to be used for the specification of lighting requirements including Illuminance, Luminance, glare, disability glare, discomfort glare, colour, colour rendering light source colour energy, maintenance, and maintenance factors. BS EN 12665 helps you satisfy the lighting requirements.
