Description

The invention relates to the field of fine arts, advertising, exhibition business, as well as signs, consisting of any graphic images, and is intended to demonstrate these images with various color dynamic effects and with a decorative principle.

A well-known advertising and information stand (certificate for utility model of the Russian Federation No. 6259, IPC G 09 F 13/12, March 16, 1998) containing a central transparent light guide plate, information stencils located on both sides of the central transparent light guide plate, two transparent polyester plates adjacent to the planes of the corresponding stencils, and light sources located on the end faces of the central transparent light guide plate. The remaining end faces of the plates are coated with an adhesive reflector to form a single package.

The device of an artwork according to the patent of the Russian Federation No. 2190538, IPC 7 V 44 C 5/08; In 44 F 1/06, 10/10/2002, which is taken as a prototype. The device contains several light guide plates installed in parallel at a distance from each other, on each of which fragments of the picture are located, and between the plates there is a light source in the place where the plot requires a natural light source. In this case, the lighting source is installed with the possibility of changing the light and color rendition.

The disadvantage of this device can be considered that this device does not provide coverage of plot areas in hard-set boundaries, as well as a low degree of contrast of images, and as a result, low transmission efficiency of artistic images. In addition, the device does not allow for multicolor light areas of the artistic image and change its contrast.

The present invention solves the problem of increasing the contrast of the illumination of plot-oriented areas of the image, as well as the formation of a wide variety of dynamically changing multi-color illumination of certain plot areas of the image at predetermined boundaries, which allows to increase the decorativeness and reliability of the artistic image.

To solve this problem, a light-dynamic device for demonstrating an artistic image is proposed, which contains a light-permeable plate with an artistic image, at least one light guide plate installed parallel to the plate with an artistic image, and a lighting source.

New in this device with respect to the prototype is that the artistic image is applied to a light-transmitting plate, behind which a light-conducting plate is placed and at least one area with a reflective coating is made in it, combined with the plot of the artistic image applied to the light-transmitting plate. An opaque background plate is placed behind the light guide plate. All plates are placed along the contour in an opaque supporting frame. The lighting source is made in the form of a group of point sources of light radiation with different wavelengths of luminescence, which are placed in the cavity of the frame with orientation to the end of the light guide plate. To enhance the visual effect, point sources of optical radiation are connected to the power source through the switching control unit, the time and period of their inclusion, and also by adjusting the brightness of their glow.

To enhance the decorative effect and the possibility of forming multicolor and dynamically changing images, it is preferable to provide the device with several light guide plates, each of which has at least one area with a reflective coating. Areas with a reflective coating of different plates are combined with the plot of the artistic image, while they may or may not coincide with the position of such areas on other plates. Each light guide plate is equipped with its own group of point sources of light radiation connected to a power source, such as a battery or battery. If the device is connected to an external voltage source, it is equipped with a power cable. Point light sources are connected to the power source through the switching control unit, the time and period of their inclusion, as well as by adjusting the brightness of their glow.

The light-dynamic device for demonstrating the artistic image on the front side can be equipped with a protective glass, and both LEDs and laser diodes or both can be used as point sources of radiation, moreover, point sources of radiation are used with different wavelengths of optical radiation.

Figure 1 presents a cross section of a light-dynamic device for demonstrating an artistic image with two light guide plates; figure 2 - section aa in figure 1, i.e. view of the light guide plates in front; and Fig.3 is a General view of the device in front in color and black and white image.

The light-dynamic device for demonstrating an artistic image contains a supporting opaque frame 1, for example, with a baguette profile. A protective glass 2 is inserted into the frame 1 and behind it, directly the art image applied on the translucent plate 3. The art image can be printed on a special translucent film of the Backlit type, or on transparent acrylic, or created by gluing translucent color films - application. In the proposed example, in the central part of the artistic image there are such elements as the view of the “mountain lake” and “sky”.

Behind the light-transmitting plate 3 with an artistic image, two light-conducting plates 4 and 5 are placed. On the light-conducting plate 4, a region with a reflective coating 6 is made, which is aligned with the location of the "mountain lake" - the plot element of the artistic image of the light-transmitting plate 3. An area with reflective coating 7, which is combined with the location of the "sky" - the plot element of the artistic image of the translucent plate 3. Reflective (reflective ivayuschie) cover 6 and 7 may be made with paint, film or sandblasting.

Behind the light guide plates 4 and 5, an opaque plate 8 is placed, playing the role of the background of the artistic image, which is made, for example, of plastic. From the back of the opaque plate 8, the housing of the switching control unit and the power source 9, equipped with a power wire 10, is attached.

In the cavity 11 of the opaque frame 1 there are groups of point sources of light radiation 12 with different emission wavelengths, which are oriented to the corresponding ends of the light guide plates 4 and 5. In this case, the point sources of optical radiation 12 are connected to the power source 9 through a switching control unit (controller), modes of time and period of their inclusion, as well as adjusting the brightness of their glow (not shown).

When the device is operated by illuminating reflective regions 6 and 7 applied to various light guide plates 4 and 5, the effect of changing the color gamut of the picture of the artistic image 3 is achieved. For example, by changing the illumination of the light reflecting region 7 of the “sky” on the light guide plate 5, imitation of the coming dawn or sunset in the "sky". Similarly, corresponding reflections are formed on the “mountain lake” by highlighting the reflective region 6 of the “mountain lake” on the light guide plate 4.

The control of point sources of illumination is carried out by means of a programmed controller that provides a change in the combination of the LEDs 12 of different glow colors in different sequences or by a random number.

The luminescence of the areas specified in the office related in the plot to the corresponding areas of the artistic image is ensured by the rigid boundary of the reflective areas on the light guide plates.

The use of the claimed light-dynamic device provides a demonstration of artistic images to obtain various color-dynamic effects of individual areas, the illumination of which is necessary according to the plot design of this image.
