Artificial lighting has become the inseparable part of humans’ modern life since the discovery of fire by prehistoric people. With the rapid development of Taiwan''s economy, people''s working styles have already changed in the development from the traditional agricultural society to the industrial and commercial society. In a long time of tight work, the past lighting has failed to meet the needs in humans’ working environment in modern society.
TAL lighting system (Task-Ambient Lighting), which was invented by Europe and the United States in 1970, has been widely used in the offices of those countries. The advantage of the lighting system is that it can improve the lighting efficiency and reduce power consumption effectively when compared to other lighting systems.
According to the form of TAL lighting, the paper is based on the experiment setting which is close to real office environment and work behavior and wants to study the influence of the psychological evaluation and performance of the testers who work in the lighting system for a long time. The results of the research are as follows:
1. In the lighting environment of TAL lighting, the lighting is more dazzling when testers are in the ambient lighting with higher color temperature.
2. In the lighting environment of TAL lighting, the lighting is more dazzling when testers are in the task lighting with higher color temperature.
3. In eight lighting environments, the testers are the most refreshed when they are in the task lighting of 13W-6500K plus the ambient lighting of 14W-3000K. On the other hand, the testers feel the most tired when they are in the ambient lighting of 14W-3000K plus no task lighting.
4. In the lighting environment of TAL lighting, testers feel comfortable with the ambient lighting of low color temperature no matter they have positive emotions or negative emotions.
5. In the lighting environment of TAL lighting, task lighting with high color temperature helps to improve the testers’ overall work performances.
6. In the lighting environment of TAL lighting, the combination of low color temperature ambient lighting and high color temperature task lighting shows improvement in positive emotions, negative emotions and working performances.
