Description

[0001] Illumination device [0002]

The present invention relates to a lighting device for shaping a petal.

2. Description of the Related Art Generally, an illumination device is a device that uses light from a light source to distribute light to a surrounding space, and examples thereof include an indoor illumination lamp or a street lamp.

Such an illumination device uses an incandescent lamp or a fluorescent lamp as a light source. Incandescent lamps are made by putting tungsten metal filaments in a vacuum glass bulb and use the principle of generating light when the temperature rises. In addition, the fluorescent lamp is turned on when an auxiliary device such as a ballast is connected. Ultraviolet radiation due to the collision of the mercury electrons and the thermoelectrons generated by the preheating of the filament due to the output from the ballast stimulates the fluorescent material to emit visible light .

However, in conventional incandescent lamps, only about 5% of the energy generated in the filament heated to about 3000 ° C is converted into light, and the remainder is released into heat, resulting in low efficiency and short life span. Since the fluorescent lamp depends on the output from the ballast in the initial operation, there is a problem in that the operation standby time is required for lighting, and the brightness and brightness of the irradiated light are low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like reference numerals refer to like elements throughout. The same reference numerals in the drawings denote like elements throughout the drawings.

1 is a perspective view showing a lighting apparatus according to an embodiment of the present invention.

The illumination device 100 of the present invention illuminates the principle of collecting and spreading petals by using illumination using a petal shape, thereby enabling light concentration and diffusion.

The lighting apparatus 100 includes a rod 120, a wing 130, a light source 140, a driving device (see FIG. 4A), and the like.

The rod 120 has an elongated shape and can extend longitudinally or laterally. The rod 120 is constructed in a hollow cylindrical shape into which wires and other components can pass.

The wing portions 131, 132, 133, 134, 130 are rotatably connected to the rod 120 and are composed of a plurality of wings. The wing portion 130 may preferably be composed of 2 to 8, for example, 4 pieces. The wing portion 130 may be formed as a streamlined plate to shape the shape of the petal.

The driving device drives the wing 130. The drive may be connected to the wing 130 via a rod 120. The wing portion 130 can be moved by a drive device between a closed mode in which a plurality of wings 130 are adjacent to each other and an open mode in which a plurality of wings 130 are spaced from each other. In the open mode, the degree to which the plurality of wings 130 are spaced apart from each other can be controlled by a driving device.

The driving device can drive the entire plurality of vanes 130 between the closed mode and the open mode at a time. Alternatively, the driving device may selectively drive only a part of the plurality of vanes 130.

The light source 140 may be disposed on the inner surface of the plurality of wings 130. The light source 140 may be disposed on 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 may be a light emitting diode (LED), an organic light emitting diode (OLED), or a laser diode (LD). The light source included in the light source 140 may be a combination of two or more of LEDs, OLEDs, and LDs.

The light source 140 may include a planar light source such as, for example, an OLED. The OLED can be driven at a low voltage and can be formed into a thin and thin shape, which is advantageous in terms of miniaturization and design of a lighting device. In the illustrated embodiment, the light source unit 140 is composed of a rectangular OLED located on the inner surface of the plate-like wing 130. The power supplied to the light source 140 may be connected through the inside of the rod 120.

The light source units 140 disposed on the inner surface of the plurality of vanes 130 can be selectively turned on or off. The shape of the light source included in the light source unit 140 or the light source unit 140 may be any shape including circular, elliptical, and other polygonal shapes.

The light emitted from the light source units 140 disposed in the plurality of vanes 130 may have different colors or luminous intensities. For example, the light source unit 140 disposed in the wing unit 130 emits red light, and the light source unit 140 disposed in the other wing unit 130 emits green light. In addition, the colors emitted from the respective light source units 140 may be changed from red to green, for example. The light intensity of the light emitted from each of the light source units 140 may be changed or the light intensity of the light emitted from each of the light source units 140 may be configured differently for each light source unit 140.

Some of the light sources 140 may be replaced by flat panel display devices. For example, instead of the light source 140, a flat panel display device may be positioned in each wing 130. Such flat panel display devices may include LCDs, PDPs, OLED display devices, and the like. In the flat panel display device located in the wing 130, various information such as brightness, mode, and color, information on the lighting device, time, weather, schedule, and the like can be displayed.

The illumination device 100 may be fixed to a ceiling, a wall surface, or the like through a bracket 110 connected to an end of the rod 120.

Fig. 2 is a perspective view showing a state in which a plurality of illumination devices shown in Fig. 1 are connected laterally. Fig.

A plurality of lighting apparatuses 100 may be connected laterally through the bracket 110. In the drawing, the left illumination device 100 is in the closed mode in which the wings 130 are adjacent to each other, and the right illumination device 100 is in the open mode in which the wings 130 are spaced apart from each other.

In the closed mode, the plurality of wing portions 130 can be adjacent to each other so that they are almost in contact with each other. In the lighting apparatus 100 of the embodiment, petals are gathered and bloomed, and the lighting apparatus 100 in the closed mode shows a shape in which petals are gathered at night. In this case, since the plurality of wing portions 130 are adjacent to each other, light emitted from the light source portion 140 located on the inner side of the wing portion 130 is concentrated around the collected wing portion 130, Cozy lighting can be produced. Such a closed mode can be used for the purpose of producing a cozy atmosphere such as a nighttime illumination lamp, for example.

Since the plurality of wings 130 are rotatably connected to the rod 120, the plurality of wings 130 in the closed mode are each capable of some degree of flow by wind. This allows the petal to shake naturally by the wind.

In the open mode, the plurality of wings 130 are spaced apart from each other to form a flower-like shape. The extent to which the plurality of vanes 130 are spaced apart from each other can be controlled by a drive device. In the open mode, the plurality of vanes 130 are spaced apart from each other as the petals are opened, so that the light emitted from the light source 140 located on the inner side of the vane 130 smoothly spreads into a wide space. In this open mode, the illumination device 100 can produce a beautiful aesthetic feeling like a flower-like shape while brightly illuminating the surroundings.

As described above, the plurality of vanes 130 move closer to the axis 121 of the rod 120 in the closed mode and move away from the axis 121 of the rod 120 in the open mode. The angle at which the wing portion 130 is deployed may be between 0 [deg.] And 90 [deg.] Relative to the axis 121 of the rod 120. [

As described above, the lighting apparatus 100 of the present invention has a shape in which a plurality of vanes 130 are connected to a rod, thereby forming flowers. The plurality of wing portions 130 can be moved between the closed mode and the open mode so as to be gathered and unfolded with respect to the axis 121 of the rod, which shapes the shape in which the petals are gathered and unfolded. When the plurality of wing parts 130 are in the closed mode, a light atmosphere can be produced. In a case where the plurality of wing parts 130 are in the open mode, the light of the light source part 140 smoothly spreads, Brightness can be brightened, and a beauty can be produced as if a flower is full. The degree to which the wings 130 are spaced apart from each other in the moving and opening modes of the wings 130 can be controlled by a driving device. In addition, the plurality of wing portions 130 may be individually moved by the driving device.

FIG. 3 is a perspective view sequentially showing a process of changing the illumination device of FIG. 1 from the closed mode to the open mode.

In the drawing, the leftmost illuminating device 100 is in the closed mode, and the illuminating device 100 is increasingly spaced apart from the plurality of wing portions 130 as it goes to the right, thereby creating a shape in which the petals are spread out.

In the open mode, the degree to which the plurality of wings 130 are spaced apart from each other can be controlled by a driving device. Further, in the closed mode, the plurality of wings 130 connected to the rod 120 can be shaken to some extent by the wind or the like, so that a natural feeling can be produced.

FIG. 4A is a view for explaining a driving apparatus of the lighting apparatus of FIG. 1, and shows a state in which the lighting apparatus is in the closed mode. FIG. 4B is a view for explaining a driving apparatus of the lighting apparatus of FIG. 1, and shows a state in which the lighting apparatus is in the open mode.

Referring to FIG. 4A, a driving device for driving the plurality of vanes 130 may be constructed of, for example, a linear actuator.

The driving device may include a motor 151, a speed reducer 152, a first driving unit 153, a second driving unit 154, a connecting member 155, and a lifting contact unit 156, for example.

The decelerator 152 is connected to the shaft of the motor 151 and serves to decelerate the rotation speed of the motor 151 to transmit the rotational force to the first hinge 153. [

The first manual gear 153 is connected to the speed reducer 152 and decelerated by the reduction ratio according to the rotation of the motor 151 and rotated. A spiral is formed on the surface of the first passive portion (153).

The second hand portion 154 is threadedly engaged with the first hand portion 153. The second hand portion 154 is guided along the inner surface of the rod 120 by screwing and moves up and down in a straight line according to the rotation of the first hand portion 153.

A connecting member 155 is fixed to the second hand portion 154. The connecting member 155 moves up and down together with the second driving unit 154 in accordance with the rotation of the motor 151.

At the end of the connecting member 155, the lifting contact portion 156 is fixed. The lifting contact portion 156 may have a disk shape. The lifting contact portion 156 is lifted and lowered together with the lifting and lowering of the connecting member 155, and is repeatedly brought into contact with and spaced from the inner surface of the streamlined wing portion 130. The outer surface of the lifting contact portion 156 may be formed with teeth that come into contact with the inner surface of the wing portion 130.

The wing portion 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 at 135.

Referring to Fig. 4B, as the motor 151 rotates, the second driving portion 154 is guided and raised by the inner surface of the rod 120. Fig. At this time, the first hand portion 153 performs a rotational motion and the second hand portion 154 performs a linear motion.

The lifting contact portion 156 integrally fixed to the connecting member 155 also rises as the second manual operating portion 154 rises. The end of the lifting contact portion 156 is lifted by lifting the wing portion 130 in contact with the inner side surface of the wing portion 130. Accordingly, the plurality of vanes 130 are in the open mode spaced apart from each other.

When the motor 151 further rotates, the lifting contact portion 156 further rises, and the plurality of wings 130 are spread out as being gradually more spaced as shown in Fig. The limit for raising and lowering the lifting contact portion 156 can be achieved by various methods such as the control of the number of revolutions of the motor 151, the limit switch, and the like.

When the motor 151 rotates in the opposite direction to switch from the open mode to the closed mode of the illumination device, the lifting contact portion 156 also descends while the second hand portion 154 descends. As a result, the lifting contact portion 156 is released from contact with the inner surface of the plurality of wing portions 130, and the plurality of wing portions 130 are gathered so as to be adjacent to each other by their own weight, thereby being in the closed mode.

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

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

The red filter 11, the green filter 12, and the blue filter 13 may be distributed over the light emitting surface as a whole. When light of red color is emitted through the light source, light emitted from the white light OLED 10 passes through the red filter 11 and is emitted through the cover 20. In addition, when it is desired to emit green or blue light, 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 lights of two or more colors to emit light of other colors than red, green, and blue.

The illumination device 100 of the present invention is configured to change the color of illumination according to the time of day and night, the psychological state of the user, the purpose of use of the illumination, and the like.

Blue light helps to stabilize and concentrate, while yellow light stimulates sympathetic nerves to promote brain information processing functions. The orange light increases confidence, and the green light helps relax the mind and relieve stress.

For example, the color or brightness of the lighting device can be controlled to automatically change according to the color temperature of the time or the outside sun (2500K to 7000K).

In addition, the expression of the moonlight before a good night's sleep and the sun's light rising in the morning after a good night's sleep can be used to adjust the color or brightness of the light to make your body and soul comfortable through artificial light.

You can also adjust the color or brightness of your lighting to match your body biorhythm or wake time.

In addition, the color or brightness of the light can be adjusted by confirming the presence of a person or object.

In addition, it is also possible to adjust the color or brightness of the illumination by selecting an appropriate mode for each learning area, for example, a mode of illumination according to a subject to be learned.

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