Light Reflectance Value Flooring

All light reflectivity values listed are based on a percentage system the higher the percentage eg.

Light reflectance value flooring.

For visually impaired people this means amongst other things that there must be a good visual contrast between various elements of the building including doorways fixtures and fittings. Forming a universal value for contrast expressed on a scale of 1 100 with 1 equalling absolute black and 100 equalling absolute white. Simply put lrv measures the percentage of light a color reflects. Lrv is defined as the amount of light reflected from a specific product measured on a scale of 0 99.

Surface reflectance greatly assists with light levels. Approximate reflectance values of typical building finishes the effect a lighting system creates in an interior is strongly influenced by the properties of the room surfaces. Lrv is defined as the amount of light reflected from a specific product measured on a scale of 0 99. Generally a floor coating with an lrv between 60 and 70 will provide the best visibility for workers without being harsh.

Therefore the contrast between for example floors and walls must achieve a certain level measured by something called light reflectance value lrv.

In architecture light reflectance value is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. Light reflectance value is represented by a number between 0 and 100 zero meaning 0 of the light waves are reflected but are instead absorbed while 100 meaning all light is completely reflected.

Understanding light reflectance values lrvs in specification colour planning and commercial fit outs is important in order to efficiently plan lighting and to provide the appropriate visual ergonomics. Areas with low reflectance levels need more light to achieve the same lux levels. The values are used by lighting designers to determine the number and type of light fixtures needed to provide pro. 20 24 35 39 the higher the light reflectance of the floor.

The higher the value obtained the greater the amount of light that is being reflected.
