The lighting method in modern times, which has developed into the level of system design, makes possible multi-dimensional lighting other than one-dimensional lighting, and has composed lighting in line with a human’s complex behavior instead of setting it uniformly. In the lighting method based on system design, it is necessary to take account of visual characteristics through simple lighting, and the complex luminance ratio through lighting creation characteristics; in addition, the index through the creation change should be preceded. This study assessed fatigue feelings consequent on creation characteristics(lighting area and space illuminance), and the results are as follows : An ideal range in time of changes in lighting creation was found to be between the same illuminance creations in case of small area & low illuminance, and in case of large area & high illuminance, the ideal range of lighting creation was found to be not only between the same illuminance creations but also in changes between the same area. Accordingly, it is necessary to pay closer attention to the use of large area & low illuminance by following presentation when developing lighting environment through dynamic changes, and to take count of the design scheme within the scope of the similar area & illuminance between creations as much as possible. Later on, the research related to lighting creation changes among the dynamic characteristics of the later lighting should be combined with discomfort glare characteristics, and should be also developed into complex researches consequent on relations with background illuminance, and light sources arrangement.

This study has found out appropriate scopes of correlated color temperature and illuminance value with regard to general diffused lighting and work in the kitchen. It also has presented appropriate photometric quantity control speed for behavioral change with the following results. 1)For general diffused lighting, the appropriate photometric quantity has turned out to be 4,000 to 4,500K in color temperature and illuminance value of 300 to 400lx. And 300lx at 4,500K has proven to be the most comfortable, behavior-appropriate, and preferred pair. 2)As far as appropriate photometric quantity for work is concerned, color temperature of 4,000 to 5,000K and illuminance value of 600 to 800lx are appropriate, while 700lx at 4,500 to 5,000K are the most comfortable, behavior-appropriate, and preferred set. 3)As for appropriate photometric quantity control speed in behavioral change, 3 to 5 seconds has proven the most comfortable, appropriate, and preferred for behavioral change from entry to general areas and 1 to 3 seconds for change from general to work.
