Description

[0001] LUMINAIRE WITH AN INTEGRATED FOLDABLE VISOR

[0002] FIELD OF THE INVENTION

[0003] The present disclosure is generally related to lighting technology and more specifically to luminaires with integrated foldable visors designed to block trespassing light emitted by the luminaires.

[0004] BACKGROUND OF THE INVENTION

[0005] Outdoor luminaires are traditionally configured to emit enough light to cover a wide area. A side effect of such expansive light emission is trespassing light, which occurs when artificial light illuminates areas where it is not intended or needed, causing unwanted or unnecessary illumination. This often happens when light spills beyond the boundaries of a property or intended area of illumination, such as onto neighboring properties, roadways, or into windows of nearby buildings. Light trespass can result in several issues. Excessive or misplaced light can cause glare, which can be uncomfortable and even hazardous for pedestrians, drivers, or occupants of nearby buildings. Also, light trespass into residential areas can disrupt sleep patterns and affect the quality of life for residents. Further, unnecessary light spillage wastes energy and contributes to light pollution, increasing energy costs and environmental impact. To mitigate light trespass, proper lighting design and fixtures with shielding structures such as louvers, visors, or baffles can be used to control the direction and spread of light, ensuring that it is directed only where needed and minimizing unintended illumination of neighboring areas. Korean Patent 102 285 371 discloses an LED street lamp with light blocking devices that each can be drawn out or drawn into a housing.

[0006] Various types of louvers, visors, and baffles can be utilized to control the direction and spread of light from luminaires, ensuring efficient lighting while minimizing light trespass and glare. For example, a full cut-off shield is a type of louver that completely blocks light emission in the upward direction, ensuring that light is only directed downwards onto the intended area and minimizing light pollution. As another example, baffle and directional louvers can be installed over a luminaire to control the direction of light by shielding it from certain angles and / or directing it in specific directions while blocking it from others. They can be designed to direct light precisely where needed while preventing glare and light trespass. Also, a hood or visor is a protruding structure installed on the luminaire to block light from spreading in unwanted directions. It effectively reduces light pollution and enhances the control of light distribution. Similarly, glare shields are often used to reduce glare by blocking direct view of the light source from certain angles. They help improve visual comfort and minimize light trespass onto adjacent properties.

[0007] These louvers, visors, baffles, and similar light-blocking shield structures are typically custom-built and / or specially designed to accommodate different lighting requirements and minimize light pollution. They are commonly available as separate accessories and may need to be specifically obtained in conjunction with a lighting installation project to be compatible with the lighting fixtures as well as the parameters for blocking trespassing light. Moreover, even then, conventional light shields are not adjustable and may not work optimally for particular installation configurations. Furthermore, attaching these structures to luminaires may compromise their performance and / or structural integrity.

[0008] Thus, a need exists for a solution for blocking trespassing light that addresses drawbacks of conventional approaches.

[0009] SUMMARY OF THE INVENTION

[0010] Accordingly, Applicants have recognized and appreciated that integrating compact foldable visors within a luminaire would allow for customizable on-demand shielding of light according to installation needs, with no detriment to the performance of the luminaire, while presenting an aesthically pleasing visual appearance and reducing total installation costs.

[0011] Accordingly, one aspect of the present disclosure relates to a luminaire having a light-emitting surface which includes a housing, an optical element and at least one adjustable visor. The optical element is attached to the housing and defines a light-emitting area within a light-emitting surface of the luminaire. The housing defines at least one slot opening formed therethrough and extending to the light-emitting surface. The adjustable visor includes a leading edge and a trailing edge and is at least partially disposed within the at least one slot opening. The visor is configured to transition from a first position to a second position relative to the light-emitting surface. When in the first position, the visor is in a collapsed configuration and the leading edge of the at least one visor is flush with or disposed behind the light-emitting surface within the housing. While in the second position, the visor is in an extended configuration, and leading edge of the at least one visor is adjustably extended and is secured at a predetermined distance from the light-emitting surface away from the housing. The visor is contained substantially within the housing when in the collapsed configuration. In some embodiments, the light source within the housing is in thermal communication with a heat sink. The light source emits light through the lightemitting surface within the light-emitting area. In the second position, the at least one visor at least partially blocks the light emitted through the light-emitting area in at least one direction.

[0012] In some embodiments, the light emitting area is generally rectangular and the housing defines at least two slot openings which are adjacent to at least two opposing sides of the light emitting area. The luminaire has at least two adjustable visors each at least partially disposed within the at least two slot openings. This at least partially blocks light in at least two directions when the visors are in the second position.

[0013] In some embodiments, the at least one slot extends through the housing at the light emitting-surface and adjacent to the light-emitting area. In some embodiments, the visor is fixedly attached to the housing at the trailing edge when in the collapsed configuration.

[0014] In some embodiments, the visor includes a plurality of pleated interconnected panels, wherein, when the visor is in the second position, adjacent panels within the plurality of pleated panels are fixedly interlocked when in the extended configuration.

[0015] In some embodiments, when in the second position, the leading edge of the visor adjustably extends to the predetermined distance from the light-emitting surface away from the housing by unfolding a predetermined number of interconnected panels. In more particular examples of these embodiments, each pair of adjacent panels of the plurality of pleated interconnected panels include interlocking snap features such that the plurality of pleated panels are fixedly interlocked when in the extended configuration upon unfolding the plurality of panels relative to each other until the snap features are engaged. The housing may further include an attachment bracket and the at least one visor is fixedly attached to the attachment bracket at the trailing edge.

[0016] In some embodiments, when the visor is in the first position, the interconnected panels are folded over one another and are substantially contained within the housing.

[0017] In some embodiments, the visor is configured to telescopically extend from the first position to the second position. In more particular examples of these embodiments, the at least one visor uses a scissor mechanism to telescopically extend from the first position to the second position. In some embodiments, the visor comprises a plurality of paneled subsections. When in the first position, the paneled subsections may be stacked side-by-side and substantially contained within the housing.

[0018] It should be appreciated that all combinations of the foregoing concepts and additional concepts discussed in greater detail below (provided such concepts are not mutually inconsistent) are contemplated as being part of the inventive subject matter disclosed herein. In particular, all combinations of claimed subject matter appearing at the end of this disclosure are contemplated as being part of the inventive subject matter disclosed herein. It should also be appreciated that terminology explicitly employed herein that also may appear in any disclosure incorporated by reference should be accorded a meaning most consistent with the particular concepts disclosed herein.

[0019] These and other aspects of the various embodiments will be apparent from and elucidated with reference to the embodiment s) described hereinafter.

[0030] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present disclosure is directed to a luminaire which includes an integrated, adjustable and foldable light visor. The visor is retained within a housing of the luminaire and can transition between a folded / collapsed and expanded position and extend beyond the lightemitting surface of the luminaire in the direction of light emission to block trespassing light.

[0032] Figures 1-2 illustrate a luminaire 100 having a light-emitting surface 105, according to various embodiments and implementations of the invention. The luminaire 100 includes a housing 110 that includes a heat sink comprising a plurality of fins 120 to draw and dissipate heat from a light source (shown in Figure 4).

[0033] The luminaire 100 further includes one or more integrated light-blocking visors 130, configured according to various embodiments of the present disclosure. As shown, the visors 130 include a leading edge 132 and a trailing edge 134 and are disposed within a slot opening 160 (e.g., as shown with reference to Figures 4) defined within and formed through the housing 110 of luminaire 100. In various embodiments, the luminaire 100 is configured to allow translational movement of the visors 130 within the slot opening 160 or transformation of the visors between a collapsed, retracted or folded and extended lightblocking positions. For example, in some embodiments, the visors 130 are configured to translate from a first position, where leading edge 132 is flush with or disposed behind lightemitting surface 105 within the slot opening 160, to a second position, where the visor is adjustably extended and secured, such that leading edge 132 is at a predetermined distance from the light-emitting surface 105. In this configuration, the visors 130 are located within the slot openings 160, stored within the luminaire 100 in the first position and deployed to adjustably shield the light emitted by the luminaire 100 on-demand when deployed in the second position. Advantegeously, when in the first position, the portion of the visors 130 extending beyond the slot openings 160 are at least partially concealed from view by the fins 120 of the heat sink. In alternative embodiments, as discussed in more detail below with reference to Figures 5-9, the visors are foldable and disposed, for the most part, or completely within the slot openings 160 when in the first position, such that only a small portion at most of the visor extends into the heat sink portion of the housing.

[0034] In various embodiments, and with additional reference to Figure 4, the luminaire 100 includes a light source 180 that emits light towards an optical element 170, such as a lens, collimator, diffuser, or combination thereof, or any other optical structure suitable for the manipulation of light emitted by the light source. The optical element 170 defines a light-emitting area within the light-emitting surface 105 of the luminaire 100. In various embodiments, the light-emitting area is generally rectangular, and the luminaire 100 includes two visors 130 at two opposing sides of, and proximate to the light-emitting area, in order to block the light emitted by the luminaire 100 through the optical element 170 in two different directions when the visors 130 are deployed in the second position.

[0035] Figure 1 demonstrates an embodiment of the luminaire 100 with the visors 130 in the first position. The leading edge 132 of the visor 130 sits flush or disposed just behind the light-emitting surface 105 of the luminaire 100 within the slot opening 160 while the trailing edge 134 of the visor 130 may sit within or extend above the fins 120 of the heat sink portion of the housing 110. The visors 130 may be generally planar, having a pair of faces perpendicular to the light emitting surface 105, while the leading edge 132 and the trailing edge 134 are parallel to the light emitting surface 105. The visors 130 may be formed of injection molded plastic or of sheet metal, or any suitable opaque material.

[0036] As further shown in Figure 1, in some embodiments, the luminaire 100 includes retaining elements, such as, for example, spring plungers 140. The retaining elements may alternatively be one or more locking pins, locking plates, or any other suitable engagement mechanism. The spring plungers 140 are configured to engage with protrusions 150 on the visors 130. A plug on the spring plungers 140 nests in gaps defined between protruding tabs 150, locking the visor 130 in place when the spring plunger is engaged.

[0037] The visors 130 are capable of translating from the first retracted (or stored) position to a maximally extended position, with Figure 2 showing a partially extended position. In the maximally extended position, the leading edge 132 is at a maximal predetermined distance from light-emitting surface 105. To adjust the visor 130 position, a user pulls the spring plunger 140 away from the visor, disengaging the plungers 140 from the protruding tabs 150. The visor 130 can then be adjusted by pulling it down through the slot opening 160 until a desired distance from the light emitting surface 105 for the leading edge 132 is reached.

[0038] Figure 3 shows a close-up view of the retaining element, in this embodiment the spring plungers 140, as engaged with the visor 130. In some embodiments, the visor 130 includes protruding tabs 150 on the inner face. The protruding tabs 150 are located in alignment with one another between trailing edge 134 and leading edge 132 of the visor 130 at intervals dimensioned to accept plunger 140. The plungers 140 are configured to have an end dimensioned to fit between pairs of protruding tabs 150 on the visor 130 to lock the visor 130 in place, and a handle end that the user may pull on to disengage the retaining element 140 from the visor 130.

[0039] The retaining element is capable of engaging with protruding tabs 150 on the visor 130 to lock the visor 130 at a desired position. To move the visor 130 to another position, a user pulls the handle end of the retaining element 140 away from the visor 130, disengaging the retaining element 140 from the protruding tabs 150 and allowing the visor 130 to translate up and down within the slot 160 of the housing 110. Once the visor 130 is at a desired position, the user simply releases or engages the retaining element, in this embodiment the spring plunger 140, such that the plunger 140 nests in a gap defined between pairs of the protruding tabs 150 of the visor 130 locking it in place.

[0040] Figure 4 shows a cutaway view of an embodiment of luminaire 100 with the visors 130 in a first position where leading edge 132 is flush with light-emitting surface 105. As shown, the visors 130 sit within the housing 110 in the slot openings 160 formed therein on either side of the light emitting area defined by the optical element 170. The visors 130, positioned on either side of the optical element 180, are flush with the light-emitting surface 105 in a stored position.

[0041] The light emitting area within the light-emitting surface 105, defined by the optical element 170, may be generally rectangular, but in other embodiments may by any suitable shape for projecting light out of the luminaire 100. Light output is generated by a light source 180, such as an array of LED light source. The light may then pass through a mixing chamber 175 before exiting the luminaire 100 through the light emitting surface 105. Notably, the configuration of the luminaire 100 shown here is only meant to be exemplary, and the principles taught in this disclosure would be equally applicable for luminaires of various different designs.

[0042] As noted above, the slot openings 160 extend through the housing 110, and as shown are positioned proximate to the light emitting area defined by the optical element 170. It should be noted that, in alternative embodiments, the slot openings 160 may be formed through the housing 110 and the optical element 170.

[0043] It should be noted that, in alternative embodiments, the slot openings 160 may be formed through the housing 110 and the optical element 170. As shown, the visors 130, positioned on either side of the optical element 180, are flush with the light-emitting surface 105 in a stored position. The embodiments illustrated in Figs. 1-4 relate to an integrated visor 130 and luminaire 100 where the visor 130 is generally planar and can slideably transition between a first position, where the leading edge 132 of the visor 130 is flush with or disposed behind the light-emitting surface 170 within the housing 110, and a second position, where the leading edge 132 of the at least one visor 130 is adjustably and slideably extended and is secured at a predetermined distance from the light-emitting surface 170 away from the housing 110. However, there are additional benefits to having the luminaire 100 and the visor arranged such that in the first position the visor is in a collapsed or folded configuration, and in the second position, the visor is in an extended or unfolded configuration. This approach could allow for a more compact integrated visor device, resulting in a luminaire that is more visually pleasing and clean in appearance, as little or no part of the visor extends from the back of the housing and is visible within the heat sink.

[0044] Accordingly, Figure 5 illustrates a luminaire 100 having a visor 530 in a collapsed configuration. The luminaire 100 shown in Figure 5 has a configuration very similar or identical to that shown in Figs. 1-4, for example including heat sink fins 120 and defining a slot 160. However, unlike the planar visors 130 previously discussed, the visor 530 shown in Figure 5 is comprised of a plurality of pleated interconnected panels 590. The interconnected panels 590 are configured to fold over one another within the slot 160 to transition from a collapsed configuration as shown in Figure 5 to an unfolded or extended configuration as shown in Figure 6. In this way, the fully folded visor 530 is able to fit compactly within the housing 110. As seen more clearly in Figure 6, the visor 530 is fixedly attached to the housing 110 at the trailing edge 534 of the visor 530, while the leading edge 532 hangs unsupported in the extended configuration. In some embodiments, the housing 110 includes an attachment bracket 535 affixed thereto, for example, to one of the fins 120, and the at least one visor 530 is affixed to the attachment bracket at the trailing edge 534, for example, via screws or adhesive.

[0045] Figure 7 shows a close-up view of the interconnected panels 590 that make up visor 530. Each the interconnected panels 590 includes one or more interlocking snap features proximate to hinges 595 such that when the interconnected panels 590 are fully unfolded and extended away from each other, this extended configuration is locked in place by the snap features. Applying force along the direction of the hinges disengages the snap feature and allows the interconnected panels to again be folded on top of one another.

[0046] As each pair of adjacent panels 590 includes its own set of snap features, the distance that the leading edge 532 of visor 530 extends from the light-emitting surface can be adjusted by unfolding a desirable number of the interconnected panels 590. For example, unfolding and snapping in place only two panels would produce a shorter extension, and correspondingly less light blockage, while unfolding and snapping in place all of the interconnected panels 590, which would lead to the maximal possible extension.

[0047] In another embodiment shown in Figure 8, a visor 830 is formed from a plurality of paneled subsections 850 that are configured to slide within one another and be secured in place, for example, by friction or scissors mechanism described below, and thereby telescopically extend the visor 830 from the first position to the second position. The paneled subsections 850 may be formed from sheet metal or injection molded plastic. The visor 830 of Figure 8, similarly to the visor 530 of Figs. 5-7, is configured to sit partially or completely within the slot 160 of a luminaire 100 and transition from a collapsed configuration to an extended configuration. In the collapsed configuration, the paneled subsections 850 are all telescoped to be stacked side-by-side next to one another so that the visor 830 fits compactly within the slot 160 of the housing 110, either completely or for the most part. In order to transition into the second position, the paneled subsections 850 are pulled away from each other to expand the length of the visor 830.

[0048] Figure 8 shows an external face of the visor 830, while Figure 9 shows an internal face of the visor 830 employing a scissors mechanism 900 that includes a plurality of support bars 910 linked over one another for extending telescoping panels. The bars are connected at pivot points 920, resembling the shape of an open pair of scissors. Each set of bars has one end fixed in place while the other end moves along a track or guide. As the panels are extended, the bars of the scissors mechanism slide and pivot, allowing for smooth and controlled expansion of the telescoping panels. This design provides stability and support while accommodating the desired extension length.

[0049] Thus, the linked support bars 910 couple the interconnected panels 850 to one another to help actuate the telescoping mechanism. As the linked support beams are brought into substantially parallel alignment with one another along the direction that the visor 830 telescopically extends, the visor 830 extends in length from the interconnected panels 850 pulling away from each other. On the other hand, when the linked support beams are brought out of substantially parallel alignment with one another along the direction that the visor 830 telescopically extends, the paneled subsections 850 telescope inside of one another to bring the visor 130 into the collapsed configuration.
