PURPOSE: A door structure of a building in which natural lighting and draft are possible is provided to naturally light through a door according to cases and enable not to reveal indoor state by making the door opaque when necessary. CONSTITUTION: A door structure of a building in which natural lighting and draft are possible comprises a globular floodlighting body(10), a support frame(20), a motor, and a control unit. The globular floodlighting body comprises a housing(14), a vent pipe(15), an opaque unit(13), a second opaque unit, and a floodlight unit(17). The globular floodlighting body selectively makes an opaque state, a floodlighting state, and a draft state. The support frame is installed in a hole formed in one side of a door(1), thereby supporting the globular floodlighting body. The motor is connected to a rotary shaft with a connector. The motor is installed in the inside of the door so that the globular floodlighting body rotates around the rotary shaft. The motor is electrically connected to the control unit. The control unit is connected to a power supply unit, a remote controller receiving unit, a communication module, and a control circuit. The control circuit receives signals of the remote controller receiving unit or communication module, thereby controlling the motor to be rotated. |
