2. Description of Prior Art

Illuminating apparatuses have gained widespread popularity. In some applications, such as with sales establishments, the use of the device is intended to gain the attention of prospective buyers. In other applications, such as in clubs, restaurants, and lounges, the intended use is merely for decorative purposes or for the amusement of patrons.

U.S. Pat. No. 3,610,918 issued Oct. 5, 1971 to Gordon A. Barlow discloses a plurality of planar reflective panels and at least one transparent panel angularly joined together to form a hollow body containing a light source. The light source along with reflections of the light source on one or more of the reflective panels is viewed through the transparent panel.

U.S. Pat. No. 3,694,645 issued Sep. 26, 1972 to Malcolm H. Brantz shows an illuminated display including a housing having a front panel through which continuously changing light patterns are viewed.

U.S. Pat. No. 3,790,772 issued Feb. 5, 1974 to Peter M. Newman et al. discloses a light box assembly which includes a box-like structure having interiorly mirrored walls and multiple light sources mounted on walls within the box which continuously activate and deactivate to change a light pattern.

U.S. Pat. No. 4,843,524 issued Jun. 27, 1989 to Edward D. Krent et al. shows furniture or the like having an illuminated, decorative design formed on at least one surface thereof.

None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

The present invention provides a light sculpture device or an article of furniture which displays a light pattern, and preferably, displays a dynamic light pattern. The device includes a plurality of planar mirrored panels, at least one of which is translucent, angularly joined together to form a box-like enclosure having interiorly reflective walls. The enclosure is mounted on a base. An intermediate top planar mirrored panel is interposed between the enclosure and the base. The top planar mirrored panel reflects interiorly of the enclosure and a light source originates thereabout. The light source may be a plurality of light sources located on pylons mounted to and extending above the top planar mirrored panel into the enclosure. Alternatively, a plurality of light sources may be recessed within the top planar mirrored panel or may be mounted beneath the top planar mirrored panel providing that pathways exist in the top planar mirrored panel which permit the passage of light therethrough. Each mirrored panel produces a reflection of the illumination light source or light sources. The illuminating light and multiple reflection produced thereby can be viewed through the translucent planar mirrored panel. The light source can be continuously activated and deactivated, such as by a noise responsive device, or a visual display can be substituted in the place of the top planar mirrored panel which can exhibit a continuously changing light pattern generated by an electronic processing system, an input device, and related software. To reduce the risk of excess heat produced by the light source, a ventilation system is provided to circulate air within the device.

Accordingly, one object of the present invention is to provide a light sculpture device which permits a viewer to view a light source as well as a series of reflections produced by the light source.

Another object of the present invention is to provide a light sculpture device having a dynamic light source which produces a continuously changing visual effect.

Another object of the present invention is to provide a light sculpture device which displays a light pattern containing a variety of colors.

Further, an object of the present invention is to provide a ventilation system to circulate air through the device, thus reducing the heat being produced by the light source.

Now referring to the drawings, FIG. 1 shows the present invention, a light sculpture device 10a or an article of furniture which displays a light pattern. The light sculpture device 10a includes generally a box-like enclosure 12a and a substantially rectangular hollow base 14.

Front and back planar mirrored panels 16a are joined to left and right planar mirrored panels 16b at right angles to form a first rectangular shaped structure 17. A translucent planar mirrored panel 22a is joined adjacent the top of the first rectangular shaped structure 17 to form the enclosure 12a having an open bottom. Silvered surfaces 18 of the planar mirrored panels 16a, 16b, 22a are located exteriorly of the enclosure 12a, thus providing reflective surfaces 20 directed interiorly of the enclosure 12a. Front and back protective panels 24a are joined substantially perpendicularly to left and right protective panels 24b to form a protective structure around the outside of the first rectangular shaped structure 17. The purpose of these protective panels 24a, 24b is to safeguard the silvered surface 18 against damage.

The hollow base 14 includes front and rear walls 28a, 28b and left and right walls 28c joined to form a second rectangular shaped structure 60. A bottom panel 26 is joined adjacent the bottom of the second rectangular shaped structure 60 and an intermediate top planar mirrored panel 38a is joined adjacent the top of the second rectangular shaped structure 60 and interposed between the enclosure 12a and the hollow base 14. The top planar mirrored panel 38a has a silvered surface 18 located interiorly of the hollow base 14. The top planar mirrored panel 38a is mounted intermediate the enclosure 12a and the hollow base 14 such that the reflective surface 20 is directed upwards through the open bottom of the enclosure 12a and interiorly of the enclosure 12a. The top planar mirrored panel 38a further includes a series of bores 46 having pylons 42 inserted therein, each pylon 42 having a light source 40a mounted thereon. Each individual light source 40a is connected in parallel by a pair of conductors 48 (also shown in FIG. 3A). The light sources 40a can be controlled either sequentially or randomly by a control device such as, but not limited to, a sound activated circuit or a voice activated circuit VAC 72 (shown in FIG. 5A) or a processing system 74, an input device 78, and accompanying software see FIG. 5B). Openings or slots 43 are provided in the top planar mirrored panel 38a to enable the heat produced by the light sources 40a to escape from the enclosure 12a. Moreover, the back wall 28b of the hollow base 14 has an exhaust fan 30 mounted thereon and the front wall 28a of the hollow base 14 includes a series of openings or slots 36 therein which in combination circulate air through the light sculpture device 10a, thus further ensuring adequate ventilation. The hollow base 14 is elevated by a set of legs 44 allowing air to circulate under the light sculpture device 10a. This gap further reduces the risk of excess heat within the light sculpture device 10a by allowing the heat to dissipate from the bottom panel 26. A power cord 34 is provided as a means to supply power from the power source 68 (shown in FIGS. 5A and 5B) for the operation of both the light sources 40a and the exhaust fan 30. A switch 32 is also provided to enable and disable the power supplied by the power source 68.

FlG. 2 illustrates an alternative embodiment to that shown in FIG. 1. A translucent planar mirrored panel 22b enables viewing to be permitted through the front of the enclosure 12b. The light sources 40a (shown in FIG. 1) as well as a series of reflections of light produced by the reflective surfaces 20 (also shown in FIG. 1) are viewed through the translucent planar mirrored panel 22b. The protective panels 24c, 24d are provided to protect the silvered surfaces (illustrated in FIG. 1) against damage.

FIG. 3A shows the pylons 42 mounted to and projecting from the bores 46 in the top planar mirrored panel 38a, each having a light source 40a mounted thereon. The light sources 40a are connected in parallel to the power source 68 (shown in FIG. 5A-5B) by the conductors 48.

An alternative placement of the light sources 40b is shown in FIG. 3B. The light sources 40b are recess mounted within the bores 46 in the top planar mirrored panel 38a and are secured by a holder 52 such as a grommet. The light sources 40b are connected in parallel to the power source 68 by the conductors 48.

Another alternative light source 40c and the placement thereof is shown in FIG. 3C. The light source 40c is supported by a series of supports 56. The light produced by the light source 40c is permitted to pass through the bores 46 and enter into and through the enclosure 12a, b.

FIG. 4A shows an alternative of the top planar mirrored panel 38b having holes 62 etched through the silvered surface 18 to allow light to pass through from the hollow base 14 to the enclosure 12a, b. The light sources 40d shown in FIG. 4B are mounted interposed between the top planar mirrored panel 38b and the bottom panel 26. The light sources 40d are connected in parallel to the power source 68 by a pair of conductors 48.

FIG. 5A shows a circuit configuration 80a wherein the power source 68 is connected in series with a switch 32 which enables and disables power to the light source 40a, 40b, 40c, 40d. Light sources 40a, 40b, 40c, 40d may include but are not limited to incandescent light sources, low voltage light sources, and light sources utilizing electrically excited gases. A transformer 70 may be required to provide a specific operating voltage. A control device, such as a sound activated circuit or a voice activated circuit VAC 72, may be used to continuously activate and deactivate the light source 40a, 40b, 40c, 40d in a random or prescribed manner.

An alternative light source 40e and circuit configuration 80b is shown in FIG. 5B. A processing system 74 and an input device 78 along with accompanying software may be used in combination with a visual display 76, such as a monochrome or color cathode ray tube, video display tube, or liquid crystal display, or some other electrical, electronic or electroluminescent display to generate an illuminating pattern. The processing system 74 and input device 78 and the accompanying software can produce and transmit either a static image or a dynamic image to the visual display 76.

It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
