When the user inputs the on / off information of the lighting for controlling the operation of the lighting unit 200 through the input unit 110, the alarm time information, the location information in which the lighting unit 200 is installed, the control manager 100 inputs the input. The stored information is stored in the memory 140 (S110).

The control manager 100 determines whether the alarm setting information is input so that the lighting is turned on at any time in step S110 (S120).

If the alarm time is set as the determination result of step S120, the current time is detected and the detected current time is compared with the set alarm time to determine whether the alarm time has been reached (S130).

The alarm time of step S130 is a time sufficient to sequentially increase the illuminance and color temperature output by the lighting unit 200 to a previous time before the alarm time set by the user.

As a result of the determination in step S130, when the alarm time is reached, the control manager 100 detects weather information of the corresponding region by providing region information of a location where the lighting unit 200 is installed to a weather information server 400 connected through a network. The memory 140 is stored in the memory 140 (S140).

The control manager 100 stores the current time information detected in the step S100 and the current weather information detected in the step S140 in a memory 140 such as sunny days, rainy days, cloudy days, and spring and summer. Control of illumination and color temperature adjustment according to the detected weather information and time by comparing with illumination information of illumination set according to season information such as autumn, winter, time information such as sunrise time and sunset time of each season, and control information of color temperature The value is detected, and the detected illuminance and color temperature control values are output to the lighting unit 200 using wireless communication such as Wi-Fi (S150).

When the lighting unit 200 is lit by the operation of step S150, the lighting unit 200 detects the illumination information through the illumination sensor unit 240, and the detected illumination information is transmitted to the control manager 100. The control manager 100 compares the received illuminance information with the illuminance information set in the control value for illuminance and color temperature adjustment detected in step S150 to determine whether a light source having an appropriate illuminance is output through the illumination unit 200 (S160). do.

As a result of the determination in step S160, when the received illuminance information is required to correct the illumination and color temperature control values below or below a preset error range, the illumination and color temperature control values are adjusted to a predetermined size (S161). After performing the step S150 again.

On the other hand, if the received illuminance information as a result of the determination in step S160 satisfies a preset error range, the control management unit 100 outputs a control signal to increase the illuminance and color temperature sequentially, the current time reaches the set alarm time It is determined whether the dimming control for the sequential increase of the illuminance and the color temperature is terminated (S170).

As a result of the determination of step S170, if the current time does not reach the alarm time, the operation S150 is performed again. If the current time reaches the alarm time, the lighting control using dimming is terminated.

Therefore, by actively controlling the lighting according to the outdoor environmental conditions and the alarm time, it is possible to maintain the optimum body rhythm by preventing the user's body rhythm from changing abruptly.
