Of Surface Reflectance On Lighting

NOT SO SCARY LIGHTING MATH - RS Lighting Design

Lighting Math Room Reflectance • Surfaces with less reflectance will bounce less light • Typical Reflectance Values: – 75%-90% White, Off White, Grey, Light tints of Blue or Brown – 30%-60% Medium Green, Yellow, Brown, or Grey – 10%-20% Dark Grey, Medium Blue – 5%-10% Dark Blue, Brown. Dark Green, and many wood finishes Room Reflectance

Daylight Sensor Design and Application Guide

– Generally one sensor per task surface – Customer would have to buy far more sensors to cover the same area • The sensor cannot distinguish between daylight fluctuations and changes of surface reflectance Open loop In this approach to daylighting, the illumination at the daylight sensor varies. It has a wide field of view;

INTERIOR LIGHTING DESIGN A STUDENT'S GUIDE

The efficacy of a lighting installation in use taking account of energy saving techniques. Operating efficacy = installed efficacy x load factor. REFLECTANCE Ratio of light reflected from a surface to the light received on it. ROOM INDEX This takes account of room proportions and height of the luminaire above the working plane.

sheen and gloss guide - Sherwin-Williams

Gloss and sheen reflectance are measured on a scale of 0 (no gloss) to 100 (mirror-like). Reflectance is typically measured by deflecting a single beam of light at a 60 or 85 degree angle off a surface. The light is deflected into a receptor, which measures the intensity in units. The higher the number of units, the shinier the surface.
