Lighting Fundamentals
Illuminance is light falling on a surface measured in footcandles. Distributed with an economic and visual plan, it becomes engineered lighting and, therefore, practical illumination.
What Are a Lighting Designer's Objectives?
A lighting designer has four major objectives:
- Provide the visibility required based on the task to be performed and the economic objectives.
- Furnish high quality lighting by providing a uniform illuminance level and by minimizing the negative effects of direct and reflected glare.
- Choose luminaires aesthetically complimentary to the installation with mechanical, electrical and maintenance characteristics designed to minimize operational expense.
- Minimize energy usage while achieving the visibility, quality and aesthetic objectives.
