- Figure 12 shows a cross-section view of another embodiment of the exemplary lighting assembly from Figure 8.
- FIGS 1 and 2 depict exemplary LED lighting assemblies 10 for a merchandise display.
- the LED lighting assemblies 10 each include a housing 12, a circuit board assembly 24, and a circuit board 16 having an LED driver circuit 22 (shown in Figure 3B).
- the housing 12 can include a series of clamps 28 for securing the housings above the area being illuminated.
- a plurality of LED emitters 20 are mounted to the circuit board 16 and are powered with the LED driver circuit 22.
- the LEDs are spaced apart from each other along the circuit board assembly 24.
- the circuit board assembly 24 is also connected to a power cord 18.
- the lenses 14 can be secured over individual LED emitters 20 to provide different refractive properties for reflecting the light emitted by the LEDs in various angles and directions such as over product shelves. As shown in Figures 3A and 3B, the lenses 14 can be provided with different refractive configurations. However, alternatively, the lenses can all be provided with the same refractive configurations. In another alternative embodiment, the lenses may be placed over every other LED to modify the light pattern. Other arrangements are also contemplated to provide optimal lighting properties and configurations depending on the environment and desired results.
- the lenses 14 may be secured to the circuit board assembly 24 via a snap fit or by any other known suitable connection.
- the lenses may be fixed individually, for example, one lens per one LED or one or more lenses may be connected together to create a uniform, one-piece lens assembly that is easier, faster, and more cost effective to install on the circuit board assembly.
- the LED lighting housing can be adjustable in several ways to adjust the orientation of the housing and to fine tune the position of the projected light.
- the housing can be adjusted on horizontal arms (not shown) that are generally perpendicular to the long edge of the shelves and positioned above the top shelf in a set of shelves. This adjustment allows the LED lighting assembly to be moved closer to or farther from the plane being illuminated.
- the second adjustment allows the assembly to rotate about its horizontal axis 26 to direct light at a different angle in the plane. The two adjustments change the angle at which the light intercepts the product faces. Moving the lighting fixture away from the product on the horizontal arms can improve the lighting on the lower positioned product by reducing shadows on the product caused by the lower shelves.
- Each of the LED lighting assemblies 10 modify the light output from the point source LED emitters 20 to illuminate an artificial planar surface area which can be represented by a front surface of product on a shelf in a retail store.
- Each LED lighting assembly can be approximately the length of a shelf in a retail store, typically 3 ft or 4ft long, or even as short as 6 inches or as long as 20 feet.
- the LED lighting assemblies 10 can be positioned in a horizontal orientation above a product on the top shelf and slightly in front of an artificial plane.
- the LED lighting assembly 10 may also be positioned in any other location with respect to the product, not necessarily only in alignment with the shelf.
- the light is modified by the plurality of lenses 14 fitted onto the circuit board 16 and over the LEDs 20 to capture the light from an LED, modify the beam pattern, and re -project the light evenly over a vertical plane in front of the product shelves.
- the lighting assembly 110 may include two opposing support arms 111 and a lighting bar 112 extending between the two support arms 111.
- the two support arms 111 may be mountable into the support posts of a gondola type merchandise display shelf.

- the lighting bar 112 may define a C-shaped configuration in cross-section.
- the lighting bar 112 may define other shapes and other sized configuration in cross- section without departing from this disclosure.
- the lighting bar 112 may act as a housing to a plurality of light emitting diodes (LED) 120 and may be configured to mount these LEDs 120 on the inside of the C-shaped cross section, as illustrated in Figures 5 and 7.
- the lighting bar 112 may be made of metal or any other suitable material.
- the LEDs 120 may be spaced along the lighting bar 112 on the inside of the lighting bar 112 as shown in Figures 5 and 7.
- the LEDs 120 may be electrically coupled together by a circuit board 116 positioned on the lighting bar 112.
- the circuit board 116 may also incorporate the appropriate resistors to control the power supplied to each LED 120.
- the LEDs 120 may provide any desired color, which may be controlled by the semiconductor material of the LED light 120. As illustrated in Figures 5 and 7, a reflector or lens 114 may be positioned around every other LED 120 on the lighting bar 112. The reflectors or lens 114 may also be placed intermittently around LEDs 120 on the lighting bar 112. The reflector or lens 114 may also be positioned in irregular patters around LEDs 120 on the lighting bar 112. The reflector or lens 114 serves the purpose of directing the emitted light in a desired direction and angle. The reflector or lens 114 may be positioned and oriented at any of the numerous possible angles to direct light in the desired direction.
- the lighting bar 112 may adequately direct light to the entire merchandise display system. For example, it is possible to position reflectors over every third or fourth LED 120, and so on. Also, it is possible for the lighting bar 112 to define other numerous shapes and configurations, depending on the type of shelf and merchandise display system on which the lighting bar 112 is used.
- the lighting assembly 210 may include two opposing support arms 211 and a lighting bar 212 extending between the two support arms 211.
- the two support arms 211 may be mountable into the support posts of a gondola type merchandise display shelf or any other similar display shelf.
- the support arms 211 and the lighting bar 212 are positioned above the top shelf of the merchandise display system.
- the support arms 211 and the lighting bar 212 can be located at any desired position on the merchandise display system.
- the lighting bar 212 may define a C-shaped configuration in cross-section.
- the lighting bar 212 may act as a housing to a plurality of light emitting diodes (LED) 220 and may be configured to mount these LEDs 220 on the inside of the C-shaped cross section, as illustrated in Figures 5 and 7.
- the lighting bar 212 may be made of metal or any other suitable material.
- the LEDs 220 may be spaced along the lighting bar 212 on the inside of the lighting bar 212 as shown in Figures 5 and 7.
- the LEDs 220 may be electrically coupled together by a circuit board 216 positioned on the lighting bar 212. [37] Generally, LEDs 220 output a directional beam 222.
- the LED 220 may also include a given beam angle 224 that is output from the LED 220.
- LEDs 220 may have beam angles 224 of approximately 80 degrees, 120 degrees, or 180 degrees. LEDs with other beam angles 224 may be utilized or incorporated with the lighting system.
- Figure 9A illustrates a beam angle 224 of approximately 80 degrees.
- Figure 9B illustrates a beam angle 224 of approximately 120 degrees.
- Figure 9C illustrates a beam angle 224 of approximately 180 degrees.
- a reflective surface 230 may be positioned near or adjacent the output of one or more of the LEDs 220.
- the reflective surface 230 may allow better control of a portion of the beam.
- the reflective surface 230 may also allow the deflection/reflection of a portion of the beam 222. Additionally, as will be explained in detail below, the reflective surface 230 may also allow the splitting or dividing of the beam 222 to thereby create multiple beams 222 projecting from the LED.
- the reflective surface is positioned adjacent to the LED 220 and the projected beam 222 of the LED 220.
- the reflective surface may direct a portion of the projected beam 222 from the LED 220 in a different direction, thereby creating two different beams of light 222 A and 222B.
- the reflective surface 230 may be positioned parallel to the path of the beam 222, but only covering and/or reflecting a portion of the beam 222.
- the reflective surface 230 is positioned parallel to the path of the beam 222, but only covering and/or reflecting approximately half of the beam 222.
- the reflective surface 230 thereby allows approximately 50% of the beam 222 to project in the direction that the LED 220 is directionally pointing (downward in this illustration), while reflecting the other 50% of the beam 222 in a direction based on the position and angle of the reflective surface 230 (horizontal in this illustration). This use of the reflective surface 230 with one LED 220 thereby can create two different LED beams 222 using just one LED 220.
- Figure 10A illustrates a first beam 222 A projecting in a downward or vertical direction, wherein the first beam 222A is not reflected from the reflective surface 230.
- Figure 10A also illustrates a second beam 222B projecting in a linear or horizontal direction, wherein the second beam 222B is reflected by the reflective surface 230.
- the LED 220 with the reflective surface 230 may create a first beam 222A that projects as a down light and a second beam 222B that projects as a back light against product shelving.
- the amount that the reflective surface reflects can be varied.
- the reflective surface may allow approximately 30% of the beam to project in the direction that the LED is directionally pointing (downward in this illustration), while reflecting the other 70% of the beam in a direction based on the position and angle of the reflective surface (horizontal in this illustration).
- the reflective surface may allow approximately 70% of the beam to project in the direction that the LED is directionally pointing, while reflecting the other 30% of the beam in a direction based on the position and angle of the reflective surface.
- the reflective surface may allow a minimal percent (just more than 0%) of the beam to 99% of the beam to project in the direction that the LED is directionally pointing, while reflecting the remaining portion of the beam.
- the reflective surface 230 may be a mirror.
- the reflective surface 230 may be other surfaces without departing from this invention, such as white/shiny, textured, or an optical film with surface coatings. Other reflective surfaces 230 not contemplated at this time may also be utilized without departing from this disclosure.
- the reflective surface 230 may be a flat reflective surface, or a flat mirror. In another embodiment without departing from this disclosure, the reflective surface 230 may be a curved reflective surface, or a curved mirror. Other surface geometry may be utilized for the reflective surface 230 without departing from this disclosure.
- Figure 10A illustrates a curved reflective surface 232.
- Figure 10B illustrates a flat reflective surface 234. Additionally, the reflective surface 230 may be an intermittent mirror or a continuous mirror without departing from this disclosure.
- the reflective surfaces 230 may be utilized at different and specified intervals throughout the series of LEDs 220.
- one individual reflective surface 230 may be utilized for each of the LEDs 220 on the lighting bar 212.
- one continuous reflective surface 230 may be utilized for all of the LEDs 220 on the lighting bar 212.
- one individual reflective surface 230 may be utilized on intermittent LEDs 220 on the lighting bar 212 at specified intervals throughout the series of LEDs. For example, if there are ten LEDs 220 on the lighting bar 212, there may be five reflective surfaces 230 utilized with five of the ten individual LEDs 220 on the lighting bar 212.
- the LEDs 220 may also include a reflector or lens 214 positioned around one or more of the plurality of LEDs 220 on the lighting bar 212.
- the reflector or lens 214 may serve the purpose of focusing and/or directing the emitted light in a desired direction and angle, and then projected onto the reflective surfaces 230.
- the reflector or lens 214 may be positioned and oriented at any of the numerous possible angles to direct light in the desired direction.
- the lighting bar 212 may adequately direct light to the entire merchandise display system. For example, it is possible to vary and/or combine different configurations of reflectors and reflective surfaces over various LEDs 220 on the lighting bar 212. Also, it is possible for the lighting bar 212 to define other numerous shapes and configurations, depending on the type of shelf and merchandise display system on which the lighting bar 212 is used.
- the modified light projected onto the products on the retail shelf is relatively consistent in brightness over the planar surface and adds sufficient relative brightness beyond the general store luminaire lighting to call attention to or highlight the product merchandised on the shelf. Also, utilizing the reflective surfaces and the lensing technique directs the available LED light such that the lighting pattern produced on the planar surface and the product faces is far more homogenous than that of a fluorescent system. Top, center, and lower product on the shelves is relatively evenly illuminated providing the desired effect for the consumer shopper.
- the modified light projected onto the products may increase shopper awareness of the products, better present the products, and increase the sales of products.
- the illuminance per watt can be higher than is generally possible with a fluorescent light, adding to a further reduction in necessary power input to achieve the desired lighting effect and energy savings. Additionally, by reflecting a portion of the total light output from the LED using appropriate reflective surfaces, the light beams can be more efficiently utilized, thereby adding to an even further reduction in the necessary power input to achieve the desired lighting effect and energy savings.
- the LED circuit board and housing is designed to be thermally efficient and to remove as much heat from the LED as possible. Projected life of the LEDs is on the order of 4-6 times than that of typical existing fluorescent lamps. This reduces service call frequency by four to five times and commensurate cost.
- Cost savings from reduced energy use and fewer service calls, along with improved sales from better product presentation may offset the cost of replacing existing fluorescent fixtures with an LED lighting fixture.
