In the open mode, the extent to which the plurality of wings 130 are spaced apart from each other may be adjusted by the driving device.

The driving device may drive the plurality of wings 130 all at once in the closed mode and the open mode.

Alternatively, the driving device may selectively drive only a part of the plurality of wings 130.

The light source unit 140 may be disposed on the inner surfaces of the plurality of wing parts 130.

The light source unit 140 may be disposed in some or all of the plurality of wings 130.

The light source included in the light source unit 140 may be a fluorescent lamp or an incandescent lamp, but preferably, may be a light emitting diode (LED), organic light emitting diodes (OLED), or a laser diode (LD).

The light source included in the light source unit 140 may be configured by a combination of two or more of LED, OLED, and LD.

The light source unit 140 may include, for example, a surface light source such as an OLED. OLEDs can be driven at low voltages and can be made thin, which is advantageous in terms of miniaturization and design of lighting devices.

In the illustrated embodiment, the light source unit 140 is composed of a rectangular OLED positioned on the inner side of the plate-shaped wing 130. Power supplied to the light source unit 140 may be connected through the inside of the rod 120.

FIG. 5 is a diagram for describing a driving device of the lighting device of FIG. 1 and illustrates a state in which the lighting device is in an open mode.

Referring to FIG. 4, the driving device for driving the plurality of wings 130 may be configured as, for example, a linear actuator.

The driving device may include, for example, a motor 151, a reducer 152, a first driver 153, a second driver 154, a connection member 155, and a lift contact 156.

The reducer 152 is connected to the shaft of the motor 151 to reduce the rotation speed of the motor 151 and to transmit the rotational force to the first driver 153.

The first driving unit 153 is connected to the reducer 152 and rotates by deceleration by the reduction ratio according to the rotation of the motor 151. The spiral is formed on the surface of the first driver 153.

The second driver 154 is screwed with the first driver 153. The second driving unit 154 is guided along the inner surface of the rod 120 by screwing according to the rotation of the first driving unit 153 to make a linear lifting movement.

The connection member 155 is fixed to the second drive unit 154. The connection member 155 moves up and down with the second driving unit 154 according to the rotation of the motor 151.

The lifting contact 156 is fixed to the end of the connecting member 155. The lifting contact 156 may have a disk shape.

The lifting contact portion 156 is lifted together as the connection member 155 moves up and down, thereby repeatedly contacting and spaced apart from the inner surface of the wing 130 formed in a streamline. A tooth or a roller contacting the inner surface of the wing 130 may be disposed on the outer surface of the lifting contact portion 156.

The wing 130 is rotatable with the end of the rod 120 as the center of rotation.

In the drawing, the center of rotation of the wing 130 is indicated by reference numeral 131.

Referring to FIG. 5, as the motor 151 rotates, the second driver 154 is guided and raised by the inner surface of the rod 120. At this time, the first driving unit 153 makes a rotational movement, and the second driving unit 154 makes a linear movement upwards.

As the second driver 154 rises, the lifting contact 156 integrally fixed to the connecting member 155 also rises. The end of the elevating contact portion 156 is lifted up by lifting the wing portion 130 in contact with the inner surface of the wing portion 130. Accordingly, the plurality of wings 130 are in an open mode spaced apart from each other.

As the motor 151 rotates further, the lifting contact portion 156 also rises while the plurality of wing portions 130 are expanded while being spaced apart as shown in FIG. 3.

The limit at which the elevating contact 156 is elevated is possible in various ways such as rotation speed control of the motor 151, limit switches, and the like.

When the motor 151 rotates in reverse to switch from the open mode of the lighting device to the closed mode again, the lifting contact 156 is also lowered while the second driving unit 154 descends. Accordingly, the lifting contact portion 156 is released from the contact state with the inner surface of the plurality of wings 130, the plurality of wings 130 are brought together to be adjacent to each other by its own weight is in the closed mode.

6 is a view for explaining an example of the principle of changing the color of the light source in a general lighting device.

As the light emitted from the white light OLED 10 passes through the red filter 11, the green filter 12, and the blue filter 13, light that is changed to each color may be emitted through the cover 20.

The red filter 11, the green filter 12, and the blue filter 13 may be distributed spaced apart from the emission surface as a whole. When the red light is to be emitted through the light source, the light emitted from the white light OLED 10 passes through the red filter 11 to emit light through the cover 20. In addition, when the light of green or blue color is to be emitted, the light emitted from the white light OLED 10 passes through the green filter 11 or the blue filter 13 and is emitted through the cover 20. It is also possible to combine light of two or more colors to emit light of colors other than red, green, and blue.

Lighting device 100 of the present invention is configured to change the color of the light according to the time, such as day and night, the psychological state of the user, the purpose of use of the light.

Blue light helps stabilize and concentrate, and yellow light stimulates the sympathetic nerve to promote brain information processing. Orange mania boosts confidence, while green shine helps to relax and relieve stress.

For example, the color or brightness of the lighting device may be automatically changed according to the time or the color temperature (2500K to 7000K) of the external sun.

In addition, by expressing the moonlight before a good night's sleep, and the rising sun light in the morning after a good night's sleep, you can adjust the color or brightness of the light to relax the mind and body through artificial light.

In addition, the color or brightness of the lighting can be adjusted according to the body biorhythm or the wake-up time.

In addition, the presence or presence of a person or object can be checked to adjust the color or brightness of the lighting.

In addition, a mode suitable for each learning area, for example, a mode of illumination may be selected according to a subject to be studied to adjust the color or brightness of the illumination.

The closed mode and the open mode of the above-described lighting device, the color of the light, the brightness and the like can be adjusted wirelessly using a remote controller.

Referring to FIG. 12, the restoring member 458 is composed of a member having an elastic force, and when the first lifting contact portion 456 is released from the inner surface of the wing portion 430, the elastic force of the restoring member 458 is released. This allows the plurality of wings 430 to return to the closed mode.

The restoring member 458 may be implemented in various forms as long as it can return the wing portion 430 to the closed mode when the first lifting contact portion 456 is released from the inner surface of the wing portion 430. For example, the restoring member 458 may be a coil spring, a leaf spring, a volute spring, a wheel spring, a spring, a disc spring, a washer spring, a snap spring. And a torsion bar spring.

Referring to FIG. 13, when the first elevating contact portion 456 descends in contact with the inner surface of the wing portion 430, the restoring member 458 is tensioned while being in contact with the outer surface of the wing portion 430, thereby restoring force. Will have The force that the first lifting contact portion 456 presses the inner surface of the wing portion 430 is greater than the restoring force of the restoration member 458, so that the plurality of wing portions 430 are kept spaced apart from each other.

When the motor 451 reversely rotates to switch from the open mode of the lighting device to the closed mode again, the first lifting contact part 456 rises to release the contact with the wing part 430. At this time, the restoring force of the restoring member 458 in contact with the outer surface of the wing portion 430 acts in the direction in which the plurality of wing portions 430 are collected again, thereby returning the wing portion 430 to the closed mode.
