Abstract

A lighting display 100 comprises an array of point light sources 104 such as LEDs that are directed towards a reflective surface 102. A shroud 106 is surrounded by the point light sources. The axes 108 of the point light sources are incident on the reflective surface 102 so that specular reflection 110 of the light is achieved by aligning the reflective surface 102 at an acute angle to the axes 108 of the point light sources 104.

Description

Lighting DisDlay The present invention relates to a lighting display, in particular a lighting display comprising an array of linear point light sources, for displaying reflective structures, and a method for the production of the lighting display.
Background of the Invention
Conventional lamps and lighting displays are well known and there are many different types of display for illuminating information boards and panels, for walkways and balustrades, to indicate stairways and for shining on plant holders and other furniture in order to crate moods as well as to achieve overall safe lighting levels.
Conventional lighting displays for displaying reflective structures, such as for example vases or walls tend to be so-called up lights and have the effect of providing an ambient light as well as illuminating a plant or tree so as to provide a specific effect.
Although successful, very little has changed with such lighting systems and so, over the years, they have tended to be all very similar. At places like point of sale (POS) displays, gallery centrepieces, architectural areas which make a visual impact and similar areas where it has been desirous to show off some item or feature, for example to prospective customers, have not always befitted as their designers or proprietors may have wanted.
The present invention addresses one or more of the disadvantages of the conventional lighting display systems. In particular, the present invention seeks to provide a lighting device which creates a striking, three-dimensional effect using light sources to present an optical illusion of rays attenuating into the distance.
Summary of the Invention
According to a first aspect, the present invention provides a lighting 0 display comprising: an array of point light sources arranged in use to be directed towards a reflective surface; and a shroud configured to surround the point light sources; in which the axes of the point light sources are arranged in use to be directed so as to be incident on the reflective surface whereby specular reflection of the light is achieved by aligning the reflective surface at an acute angle to the axes of the point light sources.
The lighting display may be configured to receive a structure providing one or more reflective surfaces. The structure may for example be a vase, plant holder, container, vessel or on a billboard, advertising stand, hoarding or on a wall.
The reflective surface preferably comprises a metallic material, such as for example brushed metallic metal. Other reflective surfaces may be used.
The metallic material preferably comprises a plurality of granular indentations.
The metallic material is preferably selected from stainless steel or aluminium, or a combination thereof The point light sources preferably comprise one or more, for example a plurality of, light emitting diodes (LEDs).
The display preferably further comprises a flashing controller arranged in use to be in communication with one or more light emitting diodes (LED5). The flashing controller is preferably arranged to switch the one 0 or more light emitting diodes on and off. Each light emitting diode may be independently controlled by the flashing controller.
Alternatively, the flashing controller may be arranged to switch on/off one or more groups of light emitting diodes independently from other groups of light emitting diodes. The flashing controller may collectively switch on and off all of the light emitting diodes as and when required.
The flashing controller may switch on and off the LEDs according to a predetermined flashing ratio. The flashing ratio is the ratio of the time period for which the LEDs are illuminated compared to the time period for which the LEDs are not illuminated. The flashing controller may be arranged such that the flashing ratio of the, or each, LED may be varied depending on the particular circumstances of the display.
The display may comprise one or more light emitting diodes of different colours.
The shroud may be arranged in use to be located around an edge of a lower region of the display.
The display is preferably formed in a substantially cylindrical or substantially prismatic form.
A substantially prismatic form may be selected from the group comprising: a triangular prismatic form, a square prismatic form, a pentagonal prismatic form, an hexagonal prismatic form, a heptagonal prismatic form, an octagonal prismatic form, and a prismatic form with ten or more faces.
The prismatic form may be truncated or in the overall form of a frustum and/or it may be tapered.
According to a further aspect of the present invention there is provided a method of manufacturing a lighting display as herein described, comprising the steps of: arranging an array of point light sources so that the axes of the point light sources are directed so as to be incident on a reflective surface of the shroud such that the reflective surface is aligned at an acute angle or substantially perpendicular to the axes of the point light sources.
The shroud may be defined by folding the reflective surface back on itself.
The lighting display may be manufactured and supplied in a flat pack or kit form so as to reduce manufacturing costs and costs of distribution and transportation.

Detailed Description of the Preferred Embodiments
Figures 1 to 6 illustrate a lighting display 100 according to one embodiment of the present invention. The lighting display 1 00 comprises a base portion 103. The base portion 103 is substantially square in cross-section. It is however to be understood that the base portion 103 may have any suitable shape depending on the requirements for the display 100.
The base portion 103 is adapted to receive a structure 101 providing a plurality of reflective brushed stainless steel surfaces 102. The base portion 103 is arranged to support the structure 101. The base portion 103 is composed of stainless steel. It is however to be understood that the base portion 103 may be composed of any suitable material. As shown in the figures, the structure 101 is arranged to be received substantially centrally with respect to the base portion 1 03. It is however to be understood that the structure may be located at any desired position with respect to the base portion 103.
The structure 101 providing the reflective surface 102 is supported on the base portion 103 and extends upwardly therefrom. The reflective surface 102 may extend upwardly from the base portion 103 at any desired angle depending on the requirements of the display 100. It can be seen from the Figures that the reflective surface 1 02 extends at an acute angle to the base portion 103.
It is to be understood that the reflective surface 102 may be provided by a single reflective surface portion or by a plurality of reflective surface portions. The number of reflective surface portions will depend on the particular requirements of the display. As shown in the figures, the reflective surface 102 comprises four reflective surface portions, only two surface portions are illustrated 102', 102".
Each reflective portion 1 02', 102" extends from the base portion 103 at the same predetermined angle. It is however to be understood that one or more, for example each, reflective portion 102', 102" may extend from the base portion 103 at a different angle to one or more of the other reflective portions 102', 1 02" depending on the requirements of the display 100.
The reflective surface 102 may be composed of any suitable material.
The reflective surface may be provided by any suitable reflective material such as for example a metallic surface. The metallic surface may be a brushed metallic surface. The reflective surface 102 of each reflective surface portion 102', 1 02" may be composed of the same material. Alternatively, one or more of the reflective surface portions 102', 102" may be composed of different materials to one or more of the other reflective surface portions 102', 102".
An array of point light sources 104, in this case LEDs, is mounted within the device 100. The array of light sources 104 may comprise any suitable number of light sources. The light sources 104 may be arranged in any suitable configuration or pattern within the array 104.
The light sources 104 are equally spaced apart from each other within io the array 104 as shown in Figure 3. It is however to be understood that the light sources 104 may be arranged within groups within the array 104.
The point light sources 104 may be any suitable light sources such as for example linear point light sources and/or LEDs.
As shown in Figure 4, the point light sources 104 are arranged such that the light source is directed towards the adjacent reflective surface portion 102', 102" of the structure 101. The light sources 104 are arranged to extend adjacent to the perimeter of the display 100, for example the perimeter of the base portion 103. Each light source 104 is fixedly mounted with respect to the base portion 103. The light source 104 is glued into position within the display 100 using adhesive such as epoxy.
The or each light source may however be rotatably mounted with respect to the base portion 1 03 such that each light source 104 may be independently orientated as desired with respect to the adjacent reflective portion 102.
A shroud 106 is configured to surround the point light sources 104. The term "shroud" is used herein to refer to any suitable covering such as for example a covered awning, shield or cowl. The shroud may be located in any suitable position. The Figures illustrate the shroud 106 as being located adjacent the base portion 103. The Figures illustrate the shroud as having a substantially square shape when viewed from above (Figure 2).
io It is however to be understood that the shroud 106 may have any suitable shape, such as for example circular, triangular, rectangular, ovaloid, depending on the requirements of the display. The shroud 106 may be formed from a portion of the base portion, such as for example by folding a portion of the material forming the base portion 103.
As shown in Figure 5, the axes 108 of the point light sources 104 are arranged so as to be incident on the reflective surface 1 02, for example the adjacent reflective surface portion 102', 102", whereby specular reflection 110 of the light is achieved. This specular reflection provides an effect of diminishing reflectivity which creates a three-dimensional optical illusion of rays attenuating into the distance. The axes 108 of the point light sources 104 are arranged to project onto the reflective surface 102 at an acute angle (that is less than 90°) with respect to the reflective surface 102.
Figure 6 illustrates the array of light sources 104 for the lighting display 100. The display 100 further comprises a flashing controller 112 arranged in use to be in communication with the LEDs 104. The flashing controller 112 is arranged to switch the one or more light emitting diodes on and off. Each light emitting diode may be independently controlled by the flashing controller. Alternatively, the flashing controller may be arranged to switch on/off one or more groups of light emitting diodes independently from other groups of light emitting diodes. The flashing controller may collectively switch on and off all of the light emitting diodes as and when required.
The flashing controller 112 may be arranged to switch on/off the one or more light emitting diodes arranged to be directed to a first reflective io surface portion 102' independently from the one or more light emitting diodes arranged to be directed to a further reflective surface portion 102".
The flashing controller 112 is arranged to switch on and off the LEDs according to a predetermined flashing ratio. The flashing ratio is the ratio of the time period for which the LEDs are illuminated compared to the time period for which the LEDs are not illuminated. It is to be understood that the flashing controller 112 may be arranged such that the flashing ratio of the or each LED may be varied depending on the particular circumstances of the display.
The display may comprise one or more light emitting diodes of different colours. The different coloured LEDs may be arranged in any suitable pattern or configuration.
The effect of the lighting display is to create an impression of depth when the array of point light sources are aligned as herein described so as to provide specular reflection of light from the reflective surface(s) of a structure, such as for example a lamp column, vase or wall. The structure is preferably tapered so as to provide one or more reflective surface(s) which extend at an acute angle to the axes 108 of the point light sources 1 04. When viewed in a darkened light the effect is exaggerated due to differing contrast. The lighting device 100 of the present invention provides an effect of diminishing reflectivity which creates a three-dimensional optical illusion of rays attenuating into the distance.
Referring now briefly to Figures 7a to 7j, which show views of a side rail io for one embodiment of a plant holder 200 that incorporates the lighting display. Figures 7b to 7e show other views of the plant holder 200 and illustrate how panels are formed and folded flat and how these panels fold and unfold so as to create the plant holder.
is These folded panels allow the plant holder to be self-assembled by way of clips, screws or other fasteners (not shown) and so enable the plant holder to be made and transported cheaply. Figures 7f and 7g show side views of the plant holder 200. Figures 7h to 7i shows views of the plant holder 200 in its flat state and demonstrate how the plant holder 200, or indeed other forms of the display, may be manufactured and supplied in a flat pack or kit form so as to reduce manufacturing.
Variation to the aforementioned embodiments may be made, for example, an array of LEDs may be arranged to direct light from a lower region of a display, container or plant holder so that ray are directed upwards. Alternatively the LEDs may be shone from a side or disposed around a cylinder.
It is understood that panels of sheet material may be supplied as preforms for self-assembly and that the panels may be designed
