Luminaire efficiency (% lamp light output transmitted out of the fixture).Characteristics of the light source and control gear.Suitability for the operating environmentĪ number of factors also affect luminaire choice:.Compatibility with existing electrical system.The following attributes should be studied when choosing the light source: Once the method of lighting has been selected, the most appropriate light source can then be chosen followed by the luminaire. will it be prismatic, low brightness or mellow light.Ĭonsideration should be given at this stage to the use of daylight to minimise the need for artificial light. will it be recessed, surface mounted, direct or indirect, or will up-lighting be used, and its primary characteristics, e.g. This includes the following:Īt this stage, consideration is given to how the light is to be delivered, e.g. This involves gaining a full understanding of what the lighting installation is intended to achieve. The five initial stages are considered in more detail in the following lines. This is the only way to build up experience to apply to future designs) (and if possible, a few months after occupation, to determine what worked and what didn’t. Inspect the installation upon completion.Calculate the lighting parameters and adjust the design as required.7 key steps in lighting design process (photo credit: )
