1 is an exemplary view showing the configuration of a lighting device.

The lighting device includes a receiver 200 for receiving weather information from the weather server 100; An input unit 300 for inputting a study timetable for each classroom; And a controller 400 for controlling the illuminance of the classroom based on the received weather information and controlling the color temperature of the classroom according to the learning timetable.

The receiver 200 receives weather information from the weather server 100. The weather server 100 generates weather information by collecting weather data from a weather sensor installed in each region. The receiver 200 receives weather information from the weather server 100 and transmits the weather information to the controller 400.

The input unit 300 inputs a learning timetable for each classroom. Schools create study schedules according to grade level progress and assign them to grade-level classrooms. The input unit 300 inputs the learning timetable made in the school as data. The input unit 300 transmits the learning timetable to the controller 400.

The controller 400 controls the illumination of the classroom based on the received weather information, and controls the color temperature of the classroom according to the learning timetable. The amount of sunlight depends on the weather information. The intensity of the classroom should be controlled by varying amounts of sunlight. The controller 400 controls the illuminance of the classroom according to the received weather information to provide the learner with appropriate brightness of light. The controller 400 may control the illuminance of the classroom based on the weather information received from the weather server 100 without using a sensor.

The controller 400 may calculate the angle of sunlight incident on the classroom by using the GPS information. The amount of sunlight varies depending on the location of the classroom depending on the angle of sunlight. For example, a window has more sunlight than a corridor. Therefore, the controller 400 controls the lighting of the windows and the hallways differently according to the sunlight angle.

When the weight is applied to the light control, the brightness of the light varies according to the value of the weight.

Different user color temperatures allow the user to adapt to the biorhythm of the user. The controller 400 may calculate a biorhythm based on the user information, and control the lighting at a color temperature corresponding to the calculated biorhythm. Biorhythm has three cycles of body, emotion, and intelligence in the human body, and these three cycles appear in a pattern as the date of birth is input, and according to the combination of these patterns, an appropriate color temperature can be given. The controller 400 may control the lighting by the color temperature based on the biorhythm.

The controller 400 may control lighting by a color temperature based on the biorhythm and the subject by combining three indexes of the body, the emotion, and the intelligence of the biorhythm, and the sensitivity of the body, the emotion, and the intelligence of the subject. Three indexes of biorhythm can be calculated from the date of birth of the user, and the three sensitivity of the subject depends on the characteristics of the subject. The controller 400 may control the color temperature based on the biorhythm and the subject. The controller 400 may control the lighting by the color temperature based on the relationship between the three sensitivity and the biorhythm of the subject. For example, when the body sensitivity of the subject is high, if the body sensitivity of the biorhythm is high, the lighting may be controlled at a color temperature corresponding to the body index. The controller 400 may control the lighting at a color temperature having a high correlation between the subject and the biorhythm.

The bio rhythm is simulated by the rhythm of the day by the sunlight, so that the controller 400 may control the color temperature based on the rhythm. In addition, the biorhythm may increase reliability by utilizing big data based on a plurality of users. In response to sunlight, the control unit 400, which collects data of illuminance and color temperature set by a plurality of users and is centrally managed by the central server and is controlled by the central server, may control the lighting by color temperature based on biorhythm.
