FIG. 2 is a perspective view illustrating a state in which a plurality of lighting apparatuses illustrated in FIG. 1 are connected laterally.

The plurality of lighting devices 100 may be connected laterally through the bracket 110. In the drawing, the lighting device 100 on the left side is in a closed mode in which the wing portions 130 are adjacent to each other, and the lighting device 100 on the right side shows a state in which the wing portions 130 are in an open mode spaced from each other.

In the closed mode, the plurality of vanes 130 may be so close as to be in close contact. The lighting device 100 of the embodiment is a shape in which the petals are collected and blooming, and the lighting device 100 in the closed mode has a shape in which the petals are collected at night. In this case, since the plurality of wing portions 130 are adjacent to each other, the light emitted from the light source portion 140 located on the inner side of the wing portion 130 is concentrated around the wing portion 130 collected, so as to bear light. Cozy lighting can be produced. Such a closed mode may be used for the purpose of creating a cozy atmosphere, for example, a night light.

Since the plurality of wing parts 130 are rotatably connected to the rod 120, the plurality of wing parts 130 may be flowed to some extent by wind in the closed mode. This makes it possible to create an aesthetic feeling that petals are naturally shaken by the wind.

In the open mode, the plurality of wings 130 are spaced apart from each other to form a flower with a wide open shape. The extent to which the plurality of wings 130 are spaced apart from each other may be adjusted by the driving device. In the open mode, since the plurality of wings 130 are spaced apart from each other as if the petals are open, light from the light source 140 located on the inner side of the wing 130 is gently spread to a large space. In this open mode, the lighting device 100 may brighten the surroundings and create a beautiful aesthetic such as flowers blooming.

As described above, the plurality of vanes 130 move closer to the shaft 121 of the rod 120 in the closed mode and move away from the shaft 121 of the rod 120 in the open mode. The angle at which the wing 130 is unrolled may be between 0 ° and 90 ° with respect to the axis 121 of the rod 120.

As described above, the lighting device 100 of the present invention has a shape in which the plurality of wings 130 are connected to the rod, thereby forming a flower. The plurality of wings 130 may be moved between the closed mode and the open mode so that they are collected and unfolded about the shaft 121 of the rod, which shapes the shape in which the petals are collected and unfolded. When the plurality of wings 130 is in the closed mode, it can produce a distant atmosphere as if it bears light. When the plurality of wings 130 are in the open mode, the light of the light source unit 140 is softly spread, At the same time, the brightness is brighter, and the flowers are aesthetically pleasing. The extent to which the wing portions 130 are spaced apart from each other in the movement and the open mode of the wing portion 130 may be adjusted by the driving device. In addition, the plurality of wings 130 may be individually moved by the driving device.

3 is a perspective view sequentially illustrating a process in which the lighting apparatus of FIG. 1 changes from a closed mode to an open mode.

In the drawing, the leftmost lighting device 100 is in a closed mode, and while going to the right, the lighting device 100 has a shape in which petals are blooming while being spaced apart from the plurality of wings 130.

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. In addition, in the closed mode, the plurality of wings 130 connected to the rod 120 may be shaken to some extent by wind or the like, thereby producing a natural feeling.

FIG. 5A 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 a closed mode. FIG. 5B 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. 5A, a driving device for driving the plurality of vanes 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 passive part 153, a second passive part 154, a connection member 155, and a lift contact part 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 passive part 153.

The first passive part 153 is connected to the speed reducer 152 and rotates by deceleration by the reduction ratio according to the rotation of the motor 151. A spiral is formed on the surface of the first passive part 153.

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

The connection member 155 is fixed to the second passive part 154. The connection member 155 moves up and down with the second passive part 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 may be formed on the outer surface of the lifting contact portion 156 in contact with the inner surface of the wing 130.

The wing 130 is rotatable about a straight line perpendicular to the axis 121 (see FIG. 2) of the rod 120. In the drawing, the center of rotation of the wing 130 is indicated by reference numeral 135.

Referring to FIG. 5B, as the motor 151 rotates, the second passive part 154 is guided and raised by the inner surface of the rod 120. At this time, the first passive part 153 makes a rotary motion, and the second passive part 154 makes a linear motion.

As the second passive part 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 back to the closed mode, the second passive part 154 descends and the lifting contact 156 also 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.
