ABSTRACT

Interior lighting was initially an engineering function with emphasis on providing adequate illumination for circulation and the performance of visual tasks-with less attention in the aesthetic aspects. A lighting designer may sometimes have little input to the preliminary and programmed design of an architectural interior space, other than the general lighting requirements, and have to act within a predetermined set of conditions. The design and layout may be identified as, general lighting, ambient lighting, localized general lighting, local lighting, task oriented lighting, and special luminous elements. The determination of the physical layout of luminaires and lighting equipment is typically established by their location in relation to the occupancy requirements, visual tasks, or special lighting effects. The visualized solution should include a pattern of illuminated surfaces, their relationship to the total environment, and how it reinforces and enables the utilization of the space-while also highlighting the important centers of interest.
