SYSTEM TO OPTIMIZE ARTIFICIAL LIGHTING LEVELS WITH INCREASING DAYLIGHT LEVEL

摘要

A kind of artificial lighting system (100) includes daylight that daylight sensor (102) are used for levels sensed, artificial light source means (104) provide a degree of artificial light, and the level that daylight control means control daylight level (108) and controller (106) control the level of artificial light depends on the daylight sensed. Controller (106) reduction the same level artificial light and the daylight for increasing level, when the daylight level sensed is lower than threshold value, reduction amount of sunlight, by controlling daylight control means (108), when the daylight level sensed is higher than threshold value.
