[0001] The present invention relates to an LED lighting control system, and more particularly, to an LED lighting control system for improving the learning ability of a student to improve learning efficiency by controlling lighting according to a situation for a specific purpose such as a classroom And more particularly, to a situation-aware LED lighting control system.

In recent years, instead of conventional fluorescent lamps and incandescent lamps, LED lamps that are environmentally friendly and have excellent energy efficiency have been widely used.

More specifically, LEDs are basically capable of controlling dimming through electrical signal control, and can precisely control the color temperature, illuminance, and color with each light source combination, There is an advantage that the lighting environment can be controlled.

In recent years, there have been a lot of researches on lighting control technology to provide visual comfort and comfort to occupants using such LED lighting and to improve working efficiency (refer to Reference 1).

However, currently, fluorescent lamps are mainly used in most schools, and these fluorescent lamps are not suitable for the dynamic lighting control as described above because they have a disadvantage that the lifetime is shortened when the blinking frequency is high.

In addition, the fluorescent lamp has been problematic in that it causes darkening of output due to occurrence of blackening phenomenon over time and non-uniformity of light distribution, resulting in decrease in visual acuity and increase in myopia ratio 2 and Ref. 3).

In addition, if the user manually controls the lighting during the class, the whole flow of the class is disturbed, which is undesirable.

Further, according to recent research results, it is known that it is possible to improve the learning efficiency of the students by providing a suitable lighting environment according to various situations such as the way of teaching and the kind of subjects, for example, In the case of providing the lighting environment considering the kind of the subject and the surrounding situation, the students' reading speed was improved by 30%, the mistake frequency was reduced by 45%, and the hyperactivity was decreased by 76% 4).

Here, the LED light source is an illumination device suitable for providing an optimum illumination environment service according to a change in the condition of an object, an environment, and the like. The LED light source is automatically applied to a classroom environment It is expected that the system of control will increase the concentration and understanding of the students and the efficiency of the learning materials of the teachers.

That is, in order to solve the problems of the conventional illumination system, as described above, there is a situation-aware LED lighting control system that automatically controls the lighting in cooperation with the sensor system and dynamically controls the illumination to provide suitable illumination for each situation It is desirable to provide an apparatus and a method that satisfy all of the above requirements.
