Description

Luminous Decorative Material {DECORATING MATERIAL WITH BACKLIGHT UNIT}

The embodiment relates to a light-emitting decorative material.

Decorative materials are used to decorate the living space beautifully and must be able to exhibit an aesthetic effect. Thus, in order to beautifully decorate the exterior or interior of furniture, home appliances, electronics, etc., a synthetic resin decorative material that is easy to process has been widely used.

Typically, a synthetic resin decorative material is manufactured by printing a pattern on a synthetic resin sheet, a film, a panel, or the like, and applying a color effect, and then coating a transparent surface layer. Such a synthetic resin decorative material, due to the simple repetition of the flat pattern, the simplicity of the pattern color, etc., is insufficient to meet the aesthetic needs of the consumer.

To improve this, a decorative material having a three-dimensional effect due to the three-dimensional pattern provided on the inside while forming a three-dimensional pattern on the surface, or by attaching a transparent layer on the three-dimensional pattern to have a flat surface.

However, the conventional decorative material has a technical limitation in forming a delicate pattern or imparting various three-dimensional feelings and colors, in particular, there is a problem that the decorative effect is not obtained at all in a low illuminance.

The embodiment provides a light-emitting decorative material that is excellent in aesthetic effects such as three-dimensional and gradation, can be changed to a variety of colors to the user's selection, and can obtain an excellent decorative effect even in a place with low illumination.

According to an embodiment, a light-emitting decorative material includes: a light-transmitting part including a decorative pattern and having light transmittance; A backlight unit including a plurality of light emitting devices having different light emitting characteristics according to characteristics of the decorative pattern of the light transmitting unit; A memory unit for storing driving information of the backlight unit; And a control unit controlling the backlight unit according to the driving information stored in the memory unit.

According to the embodiment, it is possible to provide a light-emitting decorative material which is excellent in aesthetic effects such as three-dimensional effect and gradation, can be changed to various colors for the user's selection, and can obtain an excellent decorative effect even in a place with low illumination.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the light-emitting decorative material according to the embodiment. However, in describing the embodiments, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the glass decorative material and the manufacturing method according to an embodiment of the present invention. In the description of the embodiments, each plate, film, member, mask or layer or the like is described as being formed "on" or "under" of each plate, member, film, mask or layer or the like. In the case, “on” and “under” include both being formed “directly” or “indirectly” through other components. In addition, the criteria for the top or bottom of each component will be described with reference to the drawings. The size of each component in the drawings may be exaggerated for the sake of explanation and does not mean the size actually applied.

In addition, it is also possible to allow the operation unit 42 (see FIG. 1) for operating the operation of the refrigerator to perform the function of the input unit 500 for driving setting of the light-emitting decorative material.

The memory unit 400 stores various data including driving information for driving the backlight unit 200. The driving information may be set by a designer, and the user may set new driving information or update pre-stored information through the input unit 500.

The controller 300 controls the driving of the backlight unit 200 based on a user's setting input to the input unit 500 and the memory unit 400. The controller 300 may control the blinking state, the color, and the illuminance of the backlight unit 200 according to preset driving information. The controller 300 may control the color of the backlight 200 to be changed by causing the plurality of LEDs included in the backlight 200 to blink for each predetermined color. In addition, the controller 300 may control the illuminance of each LED by adjusting the amount of current applied to the backlight unit 200, and may control the blinking state of the backlight unit 200.

For example, when a power saving mode is set when the backlight unit 200 is driven, the controller 300 may selectively turn on or turn off the backlight unit 200 only during a specific time period. Alternatively, the illumination of the backlight unit 200 may be changed according to the time zone.

In addition, when a user detection sensor or an illuminance sensor is added, the controller 300 may provide various functions according to the detection value. For example, the backlight unit 200 may be selectively turned on or the color of the backlight unit 200 may be changed depending on the proximity of the user. In addition, as the illuminance changes, the illuminance of the backlight unit 200 may also change.

By such a configuration, the light-emitting decorative material according to the present exemplary embodiment may maximize the decorative effect of the light-transmitting part 100 on which the decorative concave-convex pattern is formed by controlling the flashing state of the backlight unit 200.
