This invention generally relates to an illumination device for a retail store shelf.
Due to the variations in the amount and location of overhead lighting in retail settings, it is often the case that the labeling on retail store shelves is not properly illuminated. Especially for those labels on or near a bottom shelf, visibility may be relatively poor for many consumers such that reading the label is impossible for certain consumers whose vision is impaired in some way. Thus, it would be desirable to have a way to illuminate such labels so that regardless of its location on the store shelf, the label will be properly illuminated. A Shelf Illumination Device is disclosed in U.S. Pat. No. 9,679,503 issued to Andreas Weyer, the entire disclosure of which is incorporated herein by reference thereto.
Embodiments of the invention provides such a means for illumination of labeling on any store shelf. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.
In one aspect, embodiments of the invention provide a shelf illumination device that includes a label holder configured to hold a label and also configured for removable attachment to a front-facing end of a retail store shelf. The device includes a light bar having a plurality of light sources positioned along a length of the light bar, and with a handle attached to one end of the light bar. A carrier has a first flat portion that extends for a length at least as long the light bar. The carrier further includes a first projection and a second projection that together define an opening configured to hold the light bar. The carrier is configured for assembly to the label holder. A light-conducting member is sandwiched between the label holder and the carrier. The light-conducting member has an edge configured to receive light from a source and to conduct that light throughout the entire light-conducting member.
In a particular embodiment, the light-conducting member has a planar portion and a curved portion. In a more particular embodiment, the edge of the light-conducting member is at an end of the curved portion. The light bar may be battery-powered, and the handle may be configured to store a battery for powering the light bar.
In some embodiments, the first and second projections form a substantially rectangular opening configured to receive the light bar. In a further embodiment, the light bar is shaped as a rectangular prism such that the light bar can slide in an out of the rectangular opening defined by the first and second projections. Furthermore, the first and second projections may project from a second flat portion that connects to the first flat portion at an angle such that the first flat portion and the second flat portion are not coplanar. In some embodiments, the carrier includes a third projection proximate the second projection such that the second and third projections for a second opening configured to hold a second light bar. In other embodiments, the second flat portion is angled such that the second light bar is positioned to illuminate merchandise on a shelf below the shelf illumination device.
Additionally, the plurality of light sources may include a plurality of LEDs. In certain embodiments, the edge of the light-conducting member abuts the light bar. In a further embodiment, the carrier has a third projection proximate the second projection such that the second and third projections for a second opening configured to hold a second light bar.
In a particular embodiment, the second opening is substantially rectangular. Also, the carrier may include a third flat portion that connects to the second flat portion at an angle such that the third flat portion is not coplanar with the second flat portion or with the first flat portion. In some embodiments, the light-conducting member is transparent. In some embodiments, the label holder is transparent. In a further embodiment, the light bar is elongate.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
The shelf illumination device 100 further includes a carrier 106, a light-conducting member 108, and a label holder 110.
In particular embodiments, the light-conducting member 108 has a flat portion 112 and a curved portion 114. The flat portion 112 of the light-conducting member 108 is sandwiched between the label holder 110 and the carrier 106. The carries 106 has a first flat portion 120, which abuts the flat portion 112 of the light-conducting member 108. The carries 106 has a second flat portion 122 connected to the first flat portion 120 at an angle, i.e., a non-zero angle, such that the first flat portion 120 and the second flat portion 122 are not coplanar.
In the embodiments shown, a first projection 124 extends downward at a right angle from the second flat portion 122. A second projection 126 extends downward at a right angle from the second flat portion 122 and parallel to the first projection 124. At the end of the first and second projections 124, 126, there are perpendicular extensions 128 such that the first and second projections 124, 126 form a first substantially rectangular space or opening 130. In this case, “substantially” refers to the fact that the rectangular opening 130 is fully enclosed on three sides and partially enclosed on the fourth side where the perpendicular extensions 128 are too short to full enclose the fourth side.
A third projection 132 extends downward at a right angle from the second flat portion 122 and parallel to the second projection 126. The third projection 132 has the perpendicular extension 128 such that the second and third projections 126, 132 substantially form a second rectangular space or opening 134 that is fully enclosed on three sides and partially enclosed on the fourth side.
As shown in the
The light bar 102, which in the embodiments shown, is shaped as a rectangular prism is inserted into the first rectangular opening 130. The handle 104 of the light bar 102 can be used to insert or remove the light bar 102 from the first rectangular opening 130 of the carrier 106. As can be seen, the light bar 102, when inserted into the first rectangular opening 130, abuts an edge 136 of the light-conducting member 108. In the embodiments shown, the edge 136 is at the end of the curved portion 114 of the light-conducting member 108. From this edge 136, light from the light bar 102 is conduct throughout the curved and flat portions 114, 112 of the light-conducting member 108. This light in the light-conducting member 108 provides backlighting to illuminate any label within the label holder 110.
It can be seen from
