The Guide offers the lighting design community a set of standardized symbols that applies to all luminaires. The intent is to describe (not to prescribe) a basic symbol set and establish certain guidelines, thus making it easier to adapt computer-aided design (CAD) methods to lighting design. Through the use of the base symbol set and modifiers as described in this Guide, a symbol can be created to represent any type of luminaire. Essentially this Guide provides a set of building blocks, not a package of stand-alone symbols.
