Abstract

(57) [Summary] [Structure] A liquid crystal sheet whose state changes between a transparent state and a clouded state by controlling an applied voltage is vertically arranged from the front side to the back side, and an illuminator is provided between each liquid crystal sheet. [Effect] By controlling the voltage of a large number of liquid crystal sheets in order, the light of each illuminator can be seen and hidden from the front, creating a fantastic sense of depth as the light approaches and moves away, and the overlapping of light. A light effect is produced, and a three-dimensional decorative effect can be obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decoration device installed in a room or the like and emitting decorative light.

[0002]

[Background of the invention]

 Some lighting fixtures installed indoors place importance on their value as decorations, and this tendency has been increasing in recent years.

This invention provides a decoration device having a decorative property.

[0004]

[Means for Solving the Problems]

 This device is equipped with a large number of liquid crystal sheets that change their state between transparent and cloudy by controlling the applied voltage.The liquid crystal sheet part is erected from the front to the depth side, and between each liquid crystal sheet. And an illuminator arranged to emit light.

[0005]

[Action]

 In this decoration device, the liquid crystal sheet erected from the front side to the back side becomes transparent by turning on / off the applied voltage or changing the voltage value, and becomes slightly cloudy or almost transparent. By the time it becomes cloudy. When the transparent or cloudy state of the liquid crystal sheet changes, the light emitted from the illuminator placed behind the liquid crystal sheet may become visible, or may appear slightly blurred or completely invisible. A large number of liquid crystal sheets and illuminators are arranged side by side from the front side to the back side. As the transparent and opaque state of the liquid crystal sheet changes, the light from each illuminator can be seen and hidden so that the light approaches and moves away. A sense of depth is produced.

【Example】

 FIG. 1 is an external view of a decoration device including a liquid crystal sheet portion according to an embodiment of the present invention, FIG. 2 is a plan view of the decoration device, and FIG. 3 is a side view of the decoration device.

This decoration device includes a liquid crystal sheet portion 2 on a base portion 1. The liquid crystal sheet portion 2 is formed by arranging a number of liquid crystal sheet plates 21, 22 ... Standing from the front side to the back side. The liquid crystal sheet plates 21, 22 ... are those in which the liquid crystal sheets 21b, 22b ... Supported by an acrylic plate are fitted into the frames 21a, 22a. The liquid crystal sheet plates 21 and 22 are provided so as to be curved as shown in FIG. 2, and have an effect of slightly distorting the light from the rear.

Each of the liquid crystal sheets 21b, 22b, ... Has a transparent electrode, and a voltage application circuit is connected to the electrode. The liquid crystal sheets 21a and 22a transition from the transparent state to the cloudy state when a voltage is applied, and return to the transparent state again when the voltage is turned off. A liquid crystal sheet may be used which, on the contrary, shifts from a cloudy state to a transparent state when a voltage is applied and returns to a cloudy state when the voltage is turned off. Further, instead of the on / off control, the white turbid state may be changed by changing the applied voltage value. The liquid crystal sheets 21b, 22b, ... Of the liquid crystal sheet portion 2 are sequentially turned on / off. For example, when the liquid crystal sheet at the rear end is turned on in sequence, and finally the liquid crystal sheet 21b at the front end is turned on, the liquid crystal sheets at the front end are turned on. The control is performed such that the liquid crystal sheet 21b is turned off in the backward direction. The on / off interval of the liquid crystal sheet may be constant or may be variable.

Between the liquid crystal sheet plates 21, 22, ..., Cylindrical bodies 31, 31, ... Made of acrylic resin or the like are provided. The distal ends of the cylindrical bodies 31, 32, ... Are cut obliquely. On the other hand, light sources 41, 42, ... Are provided below the respective tubular bodies 31, 32 ,. According to this configuration, as shown in FIG. 4, when the light source 41 is turned on, the edge effect causes the light to be bent at the edge portion 31a at the tip of the tubular body 31, and the edge portion 31a becomes bright. Here, color lamps are used as the light sources 41, 42, .... In the color lamp, a warm color (red) lamp is used as the light source 41 at the front end, and a cold color (blue) lamp is used toward the rear. The arrangement of the color lamps can be set arbitrarily. Further, in this embodiment, the illuminator is provided by providing the light sources 41, 42 ... Below the cylindrical bodies 31, 32 ... Having the edge portions at the tips, but the illuminator may be configured by other methods. Good. For example, the cylindrical body may have a triangular prism shape or a flat plate shape, or the LEDs may be arranged so as to be scattered.

The liquid crystal sheet portion 2 and the illuminator are housed in a lid case 5. The lid case 5 is composed of a mirror plate having a mirror surface on the inner side, the side surface, and the upper surface, and only the front panel 5a is composed of transparent resin.

In the decoration device of this embodiment, when the light sources 41, 42, ... Are turned on and the liquid crystal sheets 21b, 22b, ... Are sequentially turned on / off, the front side is accompanied by it. The state of light seen from the outside changes. First of all, the cold color light and the warm color light are mixed, and the light of a subtle color is projected, and as the liquid crystal sheet is turned on sequentially from the rear, the light gradually goes to the warm color system. Then, it changes to a cold color or mixed color again. At this time, the light is expressed with the depth that it approaches and goes away, and the moire occurs due to the migration of the acrylic resin supporting the liquid crystal sheet and the mirror plate on the surrounding surface, and the fantastic light A staging effect can be obtained.

[0012]

[Effect of the device]

 According to this invention, the voltage of a large number of liquid crystal sheets is controlled in order, so that the light of each illuminator can be seen and hidden from the front, and the depth feeling and the overlapping of the light make the light approaching and moving away. A fantastic light effect is created and a three-dimensional decorative effect can be obtained.
