Regulation and temperature dependency of the light sources

Abstract

The paper focuses on the regulation effect on the photometric properties of the artificial light sources generally used in administrative and residential buildings. If energy consumption is one of leading areas of usage, there is an area for improvement and energy savings. There are several approaches how to achieve this aim. This attempt for energy saving is limited by standards which regulate the quality of the luminous environment; for example, illuminance level, uniformity illuminance, the colour rendering respectively colour temperature or glare requirements.
