It is composed of a plurality of crystal structure having a hexahedron or spherical shape, it is preferable to configure an amorphous state inside the lighting exterior portion in accordance with the user's operation on the lighting device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an example of the configuration of a lighting device using the refraction and scattering of light according to the present invention. In this figure, a power source for supplying power to the lighting device is not shown separately. The power source may use a battery or may be used through a transformation process using a commercial power source.

The environment detecting unit 100 includes a sensor capable of detecting the volume of sound generated in the surrounding environment of the lighting device, the brightness of the illumination due to the light generated around the lighting device, or the temperature around the lighting device. Such a sensor may use a commercially available product, and a sensor capable of detecting various physical environment changes described above may be used.

For example, the lighting device starts to light after the surroundings of the lighting device are somewhat dark. Therefore, the environment detecting unit 100 detects that the illuminance of the lighting device becomes dark to some extent and transmits it to the control unit 110.

In the lighting device according to the present invention, the power is applied, but the light is not generated yet, but the light emitting unit 120 receives a signal indicating that the controller 110 is dark from the environmental sensing unit 100. Control to generate light. The control of the controller 110 causes the light to be emitted from the light emitter 120, and at this time, adjusts the color of the light that may be generated by the light emitter 120 and the luminance for each color.

Alternatively, as opposed to the above case, when the surroundings of the lighting device are considerably brightened and the illuminance is increased, the environmental sensing unit 100 detects this and transmits it to the control unit 110, and the control unit 110 determines that the effect of lighting is not necessary and emits light. The light of the unit 120 is turned off.

The light emitting unit 120 may be implemented using a device such as a light emitting diode (hereinafter, referred to as 'LED'). The light emitting unit 120 may be implemented using only one LED when using LEDs that can produce various colors, or may be implemented using a plurality of LEDs using separate LEDs for each color. In addition, the LED can be turned on or off and the brightness can be adjusted by using the amount of current or voltage supplied to the LED, and a single LED can be used according to the amount of current or voltage supplied to the LED. It is also possible to pay.

When using a conventional LED, it may be difficult to function as a light such as reading a book with the light generated, but when using the lighting device according to the invention for the purpose of decoration or partial lighting to generate light using the LED The object can also be achieved sufficiently.

Of course, it is also possible to implement the light emitting unit 120 using other light emitting elements or light emitting means such as various color light bulbs. Since the light emitting unit 120 is implemented using an LED or using another light emitting device or light emitting means, it is easy for a person having ordinary skill in the art to which the present invention pertains, and further description thereof will be omitted.

Alternatively, when the power is applied to the lighting device and the lighting is not yet started, the environmental sensing unit 100 generates a sound of a predetermined size or more by, for example, clapping or 'turning on' in the vicinity of the lighting device. Detects a sound of a predetermined size or more and transmits it to the controller 110. The controller 110 receiving the detected result may start the lighting by controlling the light emitter 120.

On the contrary, when the applause or 'turn off' sounds during lighting to generate a sound of a predetermined size or more, the environmental sensing unit 100 detects a sound of a predetermined size or more and transmits it to the controller 110 to control the controller 110. ) May cause the light emitting unit 120 to be turned off.

In another case, when it is necessary to start the lighting that gives a warm feeling when the ambient air becomes cold, the environmental sensing unit 100 detects that the temperature around the lighting apparatus according to the present invention is lower than a predetermined temperature and controls the control unit ( 110). Similarly, the controller 110 receiving the detected result may control the light emitting unit 120 to start lighting.

Alternatively, when the surroundings of the lighting device are in a cold state below a predetermined temperature, the controller 110 controls the light emitting unit 120 to generate red or yellow light, which is a warm feeling, and when the surroundings of the lighting device are in a hot state above a certain temperature. The light emitter 120 controls to generate blue or purple light that gives a cold feeling. In one application, the controller may control the illumination to adjust the luminance of light for each color according to the change of the temperature around the lighting device.

In the cases described above, when the environment sensing unit 100 is not installed and thus does not sense the environment around the lighting apparatus according to the present invention, when power is applied to the lighting apparatus according to the present invention, the control unit 110 immediately The light emitter 120 is controlled to generate light. In addition, the controller 110 controls the luminance to be changed for each color of the light emitter 120 in a pre-stored order.

As described above, the controller 110 may be implemented using a programmable device such as an EPLD for a flexible control function of the controller 110 in which a method of controlling according to a situation may vary. Programming may be performed differently according to a place where a lighting device is to be installed using a programming device so that the controller 110 may perform various controls.

Light generated by the light emitter 120 is positioned around the light emitter 120 and scattered and refracted by the transmission / scattering part 130 that partially transmits, scatters, and refracts the light.

The transmission / scattering unit 130 may be made of a transparent or translucent material such as plastic, crystal, acrylic, etc., and partially transmits, refracts, or scatters light. The transmission / scattering unit 130 may be positioned at a predetermined distance around the light emitting unit 120 or may surround the light emitting unit 120.

In the conventional lighting device, the light goes straight through the transparent or translucent exterior part, or the lighting device obtains the effect of partially refracting and scattering the light from the exterior part of the lighting device. The light emitted by the change in the luminance is scattered and refracted through the transmission / scattering unit 130 to obtain the effect of illumination.

In the following description, the description of the transmission / scattering unit 130 will be continued.

Figure 2 shows an example of the appearance of the lighting apparatus according to the present invention. In order to understand the structure of the lighting apparatus according to the present invention is shown except for the transmission / scattering unit 130.

Environmental sensing unit 200 is located on the top of the lighting device, the control unit 210 is configured using a device such as EPLD, the light emitting unit 220-1 to 220-8 is configured using a plurality of LEDs. It is.

The light emitting units 220-1 to 220-8 may have different colors of light output from each LED so that the plurality of LEDs emit light of various colors. In addition, the luminance of the light of each LED may also change over time by the control of the controller 210.

The light emitting units 220-1 to 220-8 may be constituted by LEDs or light bulbs, and thus are weak to external shocks, and the lighting apparatus according to the present invention may affect lighting when the transmission / scattering unit, which is not shown, is contaminated. At least part of the light emitting part and the transmission / scattering part, it is preferable to further include an illumination exterior portion 290 of a transparent or translucent material having a predetermined color. The lighting exterior unit 290 may be manufactured using various materials such as glass, crystal, or plastic.

In FIG. 2, the lighting exterior part 290 is illustrated in the form of a sphere, but this is one example, and may be any shape, for example, an ellipse shape, a square pillar shape, or an arbitrary curved shape, as necessary. In addition, in FIG. 2, the lighting exterior part 290 may form a closed curved surface, but may include a partially open part. That is, as shown in Figure 2 can be configured to have a hole in any portion of the spherical illumination appearance 290.

In addition, the exterior surface of the illumination unit 290 may be colored in a single color or by using various colors. In the case of FIG. 2, the illumination exterior unit 290 may have a translucent shape.

The environmental sensing unit 200 is attached to the top of the lighting exterior unit 200, and itself is supplied with power including a small battery, or is not shown in Figure 2 through a thin line that is not easy to distinguish from the outside. It will be powered. In addition, the result detected by the environmental sensing unit 200 is connected to the control unit 210 through a wireless method or through a thin line that is not shown in FIG. 2 and is not easy to distinguish from the outside. The control unit 210 may include means for receiving a detection result of the environment around the lighting device transmitted wirelessly from the environment detection unit 200 as needed.

In FIG. 2, the position of the environmental sensing unit 200 is just one example, and may be located near the controller 210. Alternatively, if necessary, the environmental sensing unit 200 may be located outside the lighting apparatus of FIG. 2 to detect the vicinity of the lighting apparatus.

3 illustrates a state in which the transmission / scattering unit 230 is included in the lighting apparatus according to the present invention of FIG. 2.

Implementing the transmission / scattering unit 230 to have only one shape may not maximize the lighting effect using refraction and scattering. In order to maximize the lighting effect, the shape of the transmission / scattering unit 230 needs to be diversified. To this end, the transmission / scattering unit 230 is composed of a plurality of crystal structures having a shape including a tetrahedron, hexahedron or spherical shape of a predetermined size, according to the operation of the illumination device of the user of the lighting appearance unit 290 It is desirable to construct an amorphous shape inside.

In FIG. 3, the transmission / scattering unit 230 is configured using a plurality of crystal structures in the shape of a polyhedron. That is, the crystal structures having various shapes are inserted into the lighting exterior part 290 to form the transmission / scattering part 230.

Each crystal structure has a variety of shapes such as tetrahedron, hexahedron, sphere, etc. As a result, the result of refraction and scattering through each crystal structure is varied for each crystal structure, thereby enhancing the effect of decorative lighting.

In addition, each crystal structure is colored in a variety of colors to give a more varied effect on the color of the lighting.

The transmission / scattering unit 230 is a transparent or semi-transparent material that can transmit, scatter, and refract the light emitted from the light emitting units 220-1 to 220-8, thus forming the crystal structures of the transmission / scattering unit 230. Depending on the various lighting effects will occur.

By changing the size, shape, material, transmittance, and surface conditions of the crystal structure of the transmission / scattering part, various lighting effects can be produced even when other conditions are the same.

The light emitted from the light emitting units 220-1 to 220-8 has various colors, and the control unit 210 controls the light emitting unit according to the temperature, illuminance, or sound level around the lighting device detected by the environmental sensing unit 200. 220-1 to 220-8 may be turned on or off and adjust the brightness of the light output from the light emitting units 220-1 to 220-8. The adjusted light is transmitted, refracted, and reflected by the transmission / scattering unit 230 to produce various lighting effects.

In FIG. 3, when the user changes the shape in which the crystal structure constituting the transmission / scattering unit 230 is formed by shaking the lighting device, scattering and reflection effects different from those of the user may be obtained. Extremely, even when the lighting device of FIG. 3 is installed upside down, the light emitted from the light emitting parts 220-1 to 220-8 may produce various lighting effects through the transmission / scattering part 230. When changing the appearance of the transmission / scattering unit 230 by shaking the lighting device, such various effects can be changed while lighting.

In addition, since the luminance of light generated according to the passage of time or the environment around the lighting device changes, more various lighting effects can be obtained.

The lighting exterior part 290 has a spherical closed shape in FIG. 2 or 3, but the transmission / scattering part 230 is located far from the light emitting parts 220-1 to 220-8 to produce the effect of lighting. It may also be configured so that it is not to an extent. For example, the hemispherical shape may be configured such that there is no upper portion of the spherical shape. Of course, in this case, the environmental sensing unit 200 must be moved to be located at another part.
