Personal Control of Lighting :Effect of Color Temperature and Illuminance on Physiology Psychology and Productivity

Abstract

With the increasing awareness of environmental protection and carbon reduction in modern times the basic requirements for equipment have also been based on energy saving We should think about how to increase the value of the lamps and maximize its benefits to bring users the best experience rather than improving the efficiency of energy This study investigated the impact on physiology psychological perception and productivity for lighting environment The research was conducted in a laboratory and their physiological data were continuously recorded during the experiment The subject ’s(34 men and 33 women) impact on psychology is evaluated by questionnaires the physiological data evaluated by electroencephalograph and heart rate and the productivity tested by three kind of tests The experimental results found that regardless of the setting of the initial value the subjects prefers the intermediate color temperature the average value of the adjustment is 4200K and the illuminance adjustment is 500lux There is not difference on productivity between the three correlated colour temperature but the illuminance at 500lux has a better performance Warm color temperature and higher illuminance (3000K-590lux)makes subjects feel comfortable Productivity on uncontrollable lighting is better than controllable lighting
