[0001] The present disclosure relates generally to safety lighting systems and methods. More specifically, the present disclosure relates to systems and methods for providing portable safety lighting, for example, that can be visible from at least three hundred sixty degrees around a particular location, or other features.SUMMARY
[0002] In accordance with one aspect of the present disclosure, a safety light is provided. The safety light can provide multidirectional light emission and be configured for mounting or attaching to a person or structure to alert others to the presence of the person or structure. Also, the safety light can include a navigational or investigative light systems integrated therewith to deliver light that is configured for user navigation or investigation.
[0003] In some non-limiting examples, a lighting device can include a first cover, a second cover, and a lens structure positioned between the first cover and the second cover to define a periphery of the lighting device. The lens structure can include a peripheral lens configured to direct a first emission of light in an omnidirectional pattern that is visible 360 degrees about the lighting device and a beam lens configured to direct a second emission of light in a directional beam pattern. A lighting assembly can be configured to emit light through the lens structure. The lighting assembly can include a first lighting element configured to emit the first emission of light through the peripheral lens and a second lighting element configured to emit the second emission of light through the beam lens.
[0004] In some non-limiting examples, a lighting device can include a first cover, a second cover, and a lens structure positioned between the first cover and the second cover to define a periphery of the lighting device. The lens structure can include a peripheral lens configured to direct a first emission of light in an omnidirectional pattern that is visible 360 degrees about the lighting device and a beam lens configured to direct a second emission of light in a directional beam pattern. In one example, the lighting device further includes a heat sink arranged within the housing of the lighting device. The heat sink at least partially encapsulates a battery so that heat emitted from the battery flows from the battery to the heat sink, and from the heat sink to the first cover to cool the lighting device.

[0062] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology andterminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.
[0063] The term “about,” as used herein, refers to variations in the numerical quantity that may occur, for example, through typical measuring and manufacturing procedures used for articles of footwear or other articles of manufacture that may include embodiments of the disclosure herein; through inadvertent error in these procedures; through differences in the manufacture, source, or purity of the ingredients used to make the compositions or mixtures or carry out the methods; and the like. Throughout the disclosure, the terms “about” and “approximately” refer to a range of values ± 5% of the numeric value that the term precedes.
[0064] The following discussion is presented to enable a person skilled in the art to make and use embodiments of the invention. Various modifications to the illustrated embodiments will be readily apparent to those skilled in the art, and the generic principles herein can be applied to other embodiments and applications without departing from embodiments of the invention. Thus, embodiments of the invention are not intended to be limited to embodiments shown but are to be accorded the widest scope consistent with the principles and features disclosed herein. The following detailed description is to be read with reference to the figures, in which like elements in different figures have like reference numerals. The figures, which are not necessarily to scale, depict selected embodiments and are not intended to limit the scope of embodiments of the invention. Skilled artisans will recognize the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.
[0065] FIGS. 1-11 illustrate a lighting device, such as a safety light, according to aspects of the disclosure. In one example, the lighting device may be configured as a safety light 100. Safety lights may include an emergency beacon, construction lighting, mining light, police or fire lighting, ambulance lighting, or any of a variety of personal or deployable lighting. For example, personal lighting may include lighting worn on a person or integrated into clothing or otherwise mounted on a person or structure. This may include lighting mounted to hats, including hard hats. Personal lighting may also be integrated with or mounted on personal transportation, such as on bicycles, kayaks, snowmobiles, off-road vehicles, boats, and / or othertransportation systems. Personal lighting may also be integrated with specialized equipment, for example, such as skiing or snowboarding equipment, camping hiking, or fishing equipment.
[0066] Thus, in many configurations, the safety light 100 is configured as portable. In some situations, the safety light 100 may be a wearable or mountable light that can be worn by a user during use or otherwise carried with user equipment. In other situations, the safety light 100 may be integrated into or mounted on a structure, for example, a vehicle, including a car, boat, construction equipment, or other motorized and non-motorized vehicles. Irrespective of the particular use or configuration, the safety light 100 is a portable light that can be moved to or mounted on a desired location by a user. That is, the safety light 100 can be mounted to a variety of support surfaces and / or structures, for example, a piece of equipment, a vehicle (motorized or unmotorized), or other type support surface.
[0067] A lighting device (e.g., the safety light 100) is generally configured to emit light. Light can be emitted from the safety light in one or more directions. For example, light can be emitted from around at least a perimeter (i.e., an outer perimeter) of the safety light 100. Accordingly, the lighting device can be configured to direct light around an entire perimeter (i.e., a periphery) of the lighting device. Put another way, the light being emitted from the lighting device can be viewed from at least three hundred sixty degrees around the lighting device. Relatedly, to allow light to be emitted, a housing generally includes a lens. The lens can be a transparent or translucent element that can allow light to pass through. In doing so, a lens can affect various aspects of the light passing through the lens (e.g., columniation, diffusion, intensity, direction, dispersion patterns, etc.). A lens can extend along an outer perimeter of housing so that the lens defines a periphery of the lighting device (e.g., an outer periphery). Such a lens can extend along and form an entire periphery of a housing of a lighting device. However, this may not always be the case and a lens may only extend along a portion of a periphery of a housing of lighting device. Accordingly, so that light can be viewed from at least three hundred sixty degrees around the lighting device, a lighting device can include multiple lenses.
[0068] Additionally, as generally discussed herein, a lighting device can also be configured to selectively emit light along a particular direction, for example, to function as both a safety light and a navigational, investigational, or work light. To that end, in addition to providing a 360-degree emission of light, the lighting device can also be separately controlled to emit a beam of light along a particular direction (e.g., with a beam angle between about 5 degrees and about 90 degrees, or more particularly, between about 25 degrees and about 75 degrees, between about 30 degrees and about 60 degrees, between about 30 degrees and about 45degrees, or any other range therein, as required by a particular application. The beam of light can be emitted at an angle relative to the 360-degree emission of light. For example, the beam can be emitted along (e.g., at about zero degrees) to form a part of the 360-degree emission, or at another angle (e.g., about 90 degrees) relative to the 360-degree emission. To form a beam emitting portion, a lens structure can include a peripheral portion and a beam portion. The peripheral portion and the beam portion can be separate lens elements, or they can be formed together as a monolithic lens structure.
[0069] Light emitted from a lighting device (e.g., the safety light 100) can be light of one or more colors, including both visible and non-visible light (e.g., infrared light or ultraviolet (UV) light) and the light can be emitted constantly and / or intermittently. For example, a lighting device can be configured to flash or blink to cause light to emit in regular patterns and / or irregular patterns, including a continuous emissions. In some cases, light can be emitted to provide a signal to others. In particular, light can be emitted in accordance with Morse code to send a variety of messages, including but not limited to, an SOS signal. The emission of a light can also be used to convey messages to a user, for example, to indicate a battery level. Moreover, a lighting device can be configured to solely and / or simultaneously provide light with different characteristics, for example, beams (e.g., columnated beams) of light, diffused or scattered light, and any combinations thereof. Similarly, a lighting device can be configured to produce light of one or more intensities (i.e., brightness). In that regard, a lighting device can be configured to produce light at discrete intensities or over a continuous range of intensities. The characteristic of light emitted by a lighting device can be selectable by a user and can therefore be adjusted in accordance with operating conditions and the needs of the user.
[0070] In that regard, a lighting device can generally include a housing and a lighting assembly that can be configured to produce the light emitted by the lighting device. The housing can define an interior space (e.g., an enclosed interior space) and the lighting assembly can be disposed within the housing. In this way, a housing can be a protective housing that is configured to protect the lighting assembly disposed therein. For example, with continued reference to FIGS. 1-11, the safety light 100 generally includes a lens structure 104 (e.g., a lens) positioned between a first cover 108 (e.g., a bottom cover) and a second cover 112 (e.g., a top cover). The lens structure 104 can be secured between the first cover 108 and the second cover 112 in a variety of ways. For example, fasteners can be inserted through holes 318 in the first cover 108 to engage with the second cover 112. Alternatively, the covers 108, 112, can be configured to couple to the lens structure 104 with a snap-fit or press-fit connection. In otherembodiments, components of the lens structure 104, first cover 108, and the second cover 112 may be coupled together in other ways. For example, the lens structure 104, first cover 108, and the second cover 112 can be coupled together using fasteners or an adhesive. Alternatively, or additionally, the lens structure 104, first cover 108, and the second cover 112 can be fused together. In that regard, the lens structure 104, first cover 108, and the second cover 112 can be permanently or removably coupled together.
[0071] The lens structure 104, first cover 108, and the second cover 112 can collectively form a housing 117 defining an interior space 1112 (shown in FIG. 11) configured to retain a lighting assembly therein. The housing 117 can provide protection to the comparatively sensitive and fragile components of the lighting assembly, allowing the safety light 100 to be used in variety of harsh environments, for example, construction sites, factories, mines, and more generally, outdoor environments. To that end a lighting device can be configured to withstand impacts, elevated and below-freezing temperatures, and ingress from water, particulate matter (e.g., dust and debris). Further, depending on the specific use, a lighting device can be configured to be resistant to various chemicals (e.g., types of chemicals). Moreover, a lighting device can be configured to meet or exceed various industry safety standards. For example, a lighting device can be certified as “Intrinsically Safe,” in that the lighting device is explosion proof and / or ATEX certified. Such certifications and industry standards may be particularly relevant for use in the oil & gas, energy, and subterranean mining industries.
[0072] The lighting device can define a variety of shapes. That is, a housing for a lighting device can define a variety of shapes. For example, in the illustrated embodiment, the housing 117 is configured as a generally cuboid body, and more specifically, a rectangular cuboid. Put another way, the housing 117 can have sides that may not be perfectly flat, but rather have a curvature, which may aid in the emission of light from the housing 117. In other embodiments, a housing can be shaped differently, including being shaped as different regular or irregular polyhedrons (e.g., platonic solids, pyramids, and prisms, etc.), or as non-polyhedrons, for example, cylinders, hemispheres, toruses, etc.
[0073] In the illustrated embodiment, the first cover 108 can define a first side 118 (e.g., a bottom side) of the housing 117 and the second cover 112 can define a second side 119 (e.g., a top side) of the housing 117. Correspondingly, as shown in FIGS. 4-7, the lens structure 104 is positioned between the first side 118 and the second side 119 and can define a third side 217 (e.g., a front side), a fourth side 222 (e.g., a rear side), a fifth side 604 (e.g., a left side), and a sixth side 704 (e.g., a right side) of the housing 117. The first cover 108 and the second cover112 can form a sandwich arrangement with respect to the lens structure 104, in which the third side 217, fourth side 222, fifth side 604, and sixth side 704 extend substantially perpendicularly between the first cover 108 and the second cover 112. Accordingly, the lens structure 104 can form a periphery of the housing 117 between the first cover 108 and the second cover 112, and can further define an interior thickness and / or depth of the safety light 100. That is, as mentioned above, the lens structure 104 defines an opening and / or hollow section 1604 between the first cover 108 and the second cover 112 (shown in FIG. 16) configured to receive one or more components of the safety light 100. For example, the hollow section 1604 may contain a circuit board 908 configured to support and / or electrically connect various electrical components, a power source (e.g., a battery 912), and one or more lighting assemblies configured to emit light (see FIG. 9).
[0074] To provide the safety light 100 with sufficient strength and structural integrity, while also being light weight and portable, the first cover 108 and the second cover 112 can be made from polymers, such as fiber-reinforced polymers, (e.g., glass fiber or carbon fiber reinforced polymers), or metals (e.g., magnesium, titanium, aluminum, and various alloys). However, in other embodiments, a cover can be made of any other material, as is suitable for a specific application. Further, in other embodiments, a housing can include protective coatings, such as, paint, ultraviolet light resistive coatings, chemically resistive coatings, camouflage dipping, and dura-coatings. In one particular example, the housing 117 or a portion of the housing 117 (e.g., the first cover 108 and / or the second cover 112) may be made from a metallic material (e.g., aluminum, titanium, etc.) to facilitate the dissipation of heat from within the safety light 100 (e.g., from one or more LEDs, a processor, and / or a power source, etc.).
[0075] Correspondingly, the shape of the lens structure 104 can provide the safety light 100 with an optically transparent perimeter that allows light to be observed from at least three hundred sixty degrees around the safety light 100. That is, the shape of the lens structure 104 can allow light to be emitted around an entire perimeter of the safety light 100, as well as to provide another desired emission of light (e.g., a beam of light). Accordingly, the lens structure 104 can be made of a transparent or translucent material, for example, a polymer (e.g., polycarbonate, PMMA, acrylic, transparent AB S (MABS), and urethanes (Trivex®)) or a non- polymeric material (e.g., glass, such as borosilicate glasses, and optical silicones). Like with the first cover 108 and the second cover 112, the material of the lens structure 104 can be selected to provide the safety light 100 with sufficient strength and structural integrity, while also being light weight and portable. Further details regarding the lens structure 104 and the transmission (i.e., emission) of light through the lens structure 104 are described below. Insome non-limiting examples, a lens structure as described herein can be a single or monolithic lens; however, multiple lenses can be arranged to provide similar lighting characteristics are also contemplated and are within the scope of the present disclosure.
[0076] As described in greater detail below, a lighting device (e.g., the safety light 100), can be configured to provide a variety of patterns or types of emissions of light in conjunction with a lighting assembly. An emission of light from a lighting device can be controlled manually by a user or automatically. To that end, a lighting device can generally include a user interface (i.e., a control interface) configured to allow a user to control one of more functions of the lighting device. In particular a user can control the emission of light from the lighting device. That is, the control interface can allow a user to control the emission of light from a lighting assembly of the lighting device. Such control interface can be configured as physical control interfaces (e.g., buttons, switches, toggles) that are physically manipulated by a user, or as a virtual interface (e.g., buttons or other types of icons on a screen, such as a touchscreen or similar interfaces implemented via an augmented reality device). Relatedly, a user interface can be provided both on a lighting device and as a remote interface. For example, with continued reference to FIGS. 1-11, the housing 117 includes a plurality of buttons 120 that are configured to control one or more functions of the safety light 100 (e.g., controlling the emission of light from one or more lighting elements of the lighting assembly, indicating a battery level, operating a communication link, etc.).
[0077] For example, to operate the safety light 100 manually, the second cover 112 includes one or more buttons 120 configured to activate and / or adjust one or more features of the safety light 100, such as light intensity (brightness), light pattern (e.g., strobe, flash, blink, constant, etc.), or power to the light emitting elements. In some cases, buttons can also be provided to carry out other functions of the lighting device, for example to operate a communication link, record video, display diagnostic information (e.g., a state of charge of a power source, such as a battery), etc. Looking at FIG. 2, a non-limiting example arrangement of the one or more buttons 120 on the second cover 112 is shown, in which the one or more buttons 120 are integrally formed into a button layer 904 (shown in FIG. 9). The button layer may include one or more rings (e.g., rings made from a resilient material) surrounding each of the buttons 120. In one example, the rings may be integrated into the button layer to provide additional seal force between the button layer and the second cover. For example, additional seal force may be generated via compression of the rings by the second cover 112 when the safety light 100 is assembled. The additional seal force may mitigate the ingress of debris and / or liquid entering into the interior space 1112 of the safety light 100. In other non-limitingexamples, buttons can be provided separately from one another (e.g., not integrated into a button layer 904).
[0078] The button layer 904 may further include a sidewall that defines a periphery around the button layer 904 to create an internal recess within the button layer 904. In one example, the internal recess may receive a portion of the circuit board 908 so that the circuit board is securely retained around the perimeter of the circuit board via the sidewall of the button layer 904. The sidewall can also improve sealing between the lens 104 and the housing 117 (e.g., the top cover 112). In some examples, the sidewall can be configured to accommodate a connection port (e.g., a charging or data port, such as port 124) for the safety light 100. In the illustrated example, the sidewall includes a flange to accommodate connection port.
[0079] In the illustrated non-limiting example, the safety light 100 includes six buttons. A first button 204 can be configured to activate / deactivate all of the one or more light emitting elements of the safety light 100 to emit light, for example, to operate in an emergency mode in which the lighting elements are activated in one or more patterns. A second button 208 can be configured to selectively activate / deactivate one or more lighting elements to emit a beam of light from the safety light 100. A third button 212 and a fourth button 216 can be configured to activate one or more lighting elements to emit light from at least a portion of a periphery of the safety light 100 (e.g., from the third side 217, fourth side 222, fifth side 604, or sixth side 704 to produce part or all of a 360-degree emission), For example, the third button 212 can selectively activate lighting elements on each of the third side 217, fifth side 604, and sixth side 704 to form a first portion of the 360-degree emission and the fourth button 216 can selectively activate lighting emitting elements on the fourth side 222, fifth side 604, and sixth side 704 to form a second portion of the 360-degree emission, which collectively form the 360- degree emission. A fifth button 220 can be configured to activate / deactivate the lighting element 1908 associated with a secondary lens 116 of the safety light 100. A sixth button 224 can be configured to modify one or more light emission patterns of the one or more light emitting elements of the safety light 100. For example, the sixth button 224 may adjust the light intensity (brightness), light pattern (e.g., strobe, flash, blink, constant, etc.), and / or other features of the safety light 100. Additionally, the sixth button 224 may enable and / or disable wireless communications, such as Bluetooth and / or radio frequency (RF) communications, put the safety light 100 into a pairing mode, and / or other wireless communication functions. In other non-limiting examples, more or fewer buttons can be included, and any buttons may be configured differently to control any functions of a lighting device.
[0080] With additional reference to FIG. 11, the button layer 904 can be positioned below the second cover 112, between the second cover 112 and the lens structure 104. Correspondingly, the second cover 112 can include plurality of holes, each configured to allow a corresponding one of the buttons 120 to extend therethrough. In this way, the buttons 120 are exposed on the exterior of the housing 117 to allow access to the one or more buttons 120 by a user. Correspondingly, the circuit board 908 is oriented below the button layer 904 so that actuation (e.g., pressing) of the one or more buttons 120 causes the actuated button to contact the circuit board 908 (e.g., at a capacitive contact), creating an electrical connection between the button layer 904 and the circuit board 908. In response to actuation of a button 120, the circuit board 908 (e.g., a controller coupled to the circuit board 908) can control a flow of electrical current to one or more lighting elements to control an emission of light from the lighting device.
[0081] In some cases, a lighting device can also be operated automatically, without needing a physical input from a user. For example, a lighting device can be configured to control an emission of light based on one or more detected environmental conditions (e.g., an ambient light level, presence of moisture, GPS position, impacts, etc.). In other cases, a lighting device can also be controlled based on an external signal that is received by the safety light (e.g., a Bluetooth, radio, or other type of wireless communications). In this way, the lighting device can be controlled without requiring a physical input from a user.
[0082] To provide the electrical power for operation of the safety light 100, the circuit board 908 can be coupled to a power source that is configured to store energy for later use by the safety light 100. Here the power source is configured as a battery 912, and more specifically a lithium-ion battery, although other types of power sources, including batteries with different chemistries (e.g., alkaline, nickel metal hydride, lithium-iron-phosphate, etc.), which may or may not be rechargeable. In one example, where a power source is a non-rechargeable battery, a lighting device can be configured to permit replacement of the battery, for example, via an access port or removal of a housing cover. During operation of a safety light, heat can be generated by a variety of components, including a power source, processer, lighting elements, etc. Typically, as light output increases, so does the heat generated by the safety light. The heat generated by the safety light can be dissipated to the surrounding environment to ensure optimal light performance. To improve heat dissipation, a safety light can include a heat sink to collect and dissipate heat. For example, a dedicated heat sink can be provided, or a housing cover can be configured to function as a heat sink. In one particular example, the battery 912 may include a housing (e.g., an exterior metallic surface), which may permit efficient heattransfer away from the battery 912. For example, the housing may transfer heat from the battery 912 to a heat sink within the safety light 100. The heat sink may be positioned within an interior cavity of the safety light 100, between the circuit board 908 and the first cover 108. In one example, the heat sink may include a cutout shaped to receive and secure the battery 912 therein. Thus, the battery 912 may be partially encapsulated within the cutout, in direct contact with the heat sink, so that heat is transferred through the heat sink away from the battery 912.
[0083] In one particular example, the heat sink may include a series of ridges along opposing sidewalls of the heat sink. The sidewalls may wrap around opposing sides of the battery 912, so that heat from the battery 912 is dissipated through the heat sink (e.g., via the ridges). Further, a base of the heat sink extending between the sidewalls may be in direct contact with the first cover 108 and the magnet, which may permit heat transfer from the heat sink to the first cover 108 and / or magnet. Put differently, the heat sink (e.g., the base of the heat sink) may be positioned between the battery 912 and the first cover 108, so that heat may flow from the battery into the heat sink and dissipate (e.g., via convection and / or conduction) through the first cover 108 and / or magnet. As should be appreciated, in some examples, the heat sink may be integrated into the housing of the battery 912 as an assembly. Further, the heat sink may be made from a highly-conductive material, such as a metallic material (e.g., aluminum, copper, titanium, etc.) to permit efficient heat transfer.
[0084] In one example, a power source can be indirectly supported by the circuit board 908 via wires that electrically connect the power source to the circuit board 908, or a power source can be directly supported by the circuit board 908. In some embodiments, the wires can removably couple (e.g., via a connector) to the circuit board 908 to allow for the battery 912 to be replaced. The battery 912 can be positioned below the button layer 904 and the circuit board 908 and can be in electrical connection with the circuit board 908 and the one or more lighting assemblies. Such arrangements can provide for improved packaging within a housing of a lighting device, as described in greater detail below, as well as allowing for larger batteries to be used, thereby increasing runtime. The battery 912 may be charged via wireless charging and / or via a data transfer / charge port 124 (see FIG. 1).
[0085] A lighting device can also be provided with connection structures or features, that can allow the lighting device to be mounted to a support structure or support surface. That is, a lighting device can be configured to physically (e.g., via fasteners, clips, and brackets) or magnetically couple to a support structure or surface (e.g., a light bar, a charging dock, a panel of a vehicle, and a hard hat). In some cases, a lighting device may include an accessory that acts as an intermediary to allow the lighting device to couple to a structure in a beneficial way.For example, some non-limiting examples of accessories include a headbands, adjustable straps, lanyards, tilting mounts, inserts for traffic cones, auxiliary battery packs, and clips.
[0086] In some cases, connection structures can be configured to provide one or more magnetic connections. Magnets that can provide strong magnetic coupling are preferrable to allow a lighting device to be mounted securely to a wider variety of articles. For example, a magnet can be made of a strong magnetic material, such as a rare earth magnet (e.g., a Neodymium or Samarium Cobalt magnet). Relatedly, multiple magnets may be arranged to provide an enhanced (i.e., stronger) magnetic connection. For example, magnets can be arranged as a Halbach array, which can provide a strong magnetic field on one side and a weak field on the other. Accordingly, a stronger magnetic coupling can be provided while minimizing any potential magnetic interference with, for example, electrical components of a lighting assembly or wireless communications.
[0087] A magnet or other connection structures can be secured to a housing of a lighting device. In particular, such connection structures can be disposed on an exterior of a housing or within a housing. More specifically, a magnet can be secured within a housing, for example, via a press or interference fit connection, fasteners, brackets, and / or adhesives. For example, turning to FIG. 3, the first cover 108 can be configured to couple to a magnet 936. As illustrated, the first cover 108 may include a magnet tray 304 that is configured to selectively house and retain a magnet 936 (see FIG. 9). The magnet 936 may be used to quickly and selectively mount the safety light 100 in various locations, such as on a vehicle, on clothing, on predetermined accessories, and / or other magnetic locations. In particular, the magnet 936 can allow the safety light 100 to be attached directly to a magnetic support structure, or to a non-magnetic structure via an accessory that can couple to the safety light 100 (e.g., a magnetic accessory that can magnetically couple to the safety light 100).
[0088] When the safety light 100 is coupled with (i.e., magnetically coupled with) an accessory, an article (i.e., object) can be disposed between the accessory and the safety light 100 (e.g., the magnet 936) to attach the safety light 100 to said article. For example, a clothing item (e.g., a jacket, a shirt, pants, a belt, or headwear) may be disposed between the mounting plate and the magnet 936, wherein the magnet 936 is coupled to the mounting plate through the clothing item, thereby releasably attaching the safety light 100 to the clothing. Some nonlimiting examples of articles include clothing, helmets, backpacks, belts, tents, windows, boats (e.g., boat siding), containers, road signs, and combinations thereof. In that regard, an accessory can be configured differently, for example, as a clip, a strap, mounting plates and / or brackets,etc. In that regard, a non-limiting example of a mounting plate is the mounting plate disclosed in U.S. Pat. No. 9,478,108, the entire disclosure of which is incorporated by reference herein.
[0089] Further, in some embodiments, a housing of a lighting device can further include other types of connection structures. That is, a housing can be further configured to provide structural or electrical connections with external structures (e.g., external devices). In some cases, such connection structures can serve as locating or orientating features configured to allow the lighting device to couple with another object in a specific way. For example, one or more alignment protrusions 308 may surround the magnet tray 304. The alignment protrusions 308 may serve as orienting and / or aligning apertures to assure proper alignment of the magnet tray 304 on a charger and / or wireless data transfer device. In other examples, the alignment protrusions 308 may be used in combination with one or more predetermined accessories and / or mounting device to secure the safety light 100 in place.
[0090] In some cases, a lighting device can also have other types of attachment points, as may provide for different types of couplings. For example, the first cover 108 may be molded and / or formed to further define a mounting point 504 (shown in FIGS. 5 and 8), which is configured to receive a lanyard and / or other connection device. The mounting point 504 may receive a lanyard to attach the safety light 100 to a user, a vehicle, and / or other device to prevent loss of the safety light 100. To further assist in permanent and / or temporary mounting of the safety light 100, the safety light 100 can include one or more inserts 312 provided on the alignment protrusions. In some cases, the inserts 312 can be threaded inserts configured to receive a fastener, such as a threaded fastener to secure the safety light 100 into a desired position. Alternatively, the inserts 312 can be configured as terminals to provide other types of connections, for example, to provide electrical connections for internal components within the safety lights, such as for charging, communication, etc.
[0091] Continuing, and as mentioned above, a lighting device generally includes a lens that is configured to direct and control the output of light from a lighting assembly. That is, a lens can be tailored to provide a desired output of light, for example, by controlling the refraction of reflection of light passing through the lens. In that regard, a lens can be configured direct and control light from a light source (e.g., lighting elements of a lighting assembly) to produce, for example, a single beam or multiple beams of light (e.g., columnated, high-intensity light) that can be observed over long distances (e.g., up to a mile, or greater than five miles, or anywhere therebetween), or to create a comparatively diffuse or low-intensity light for indoor use, or for use as a work light. The amount of diffusion and columniation of the light can be tailored for specific applications. In addition to refracting light, a lens can also be configuredto reflect light within the lens, for example, by adding a reflective coating or angling a surface of the lens to cause total internal reflection of the light. In the regard, a lens can be configured as a prism, which can direct light in a transverse direction. More specifically, light can be directed via total internal reflection and / or or by a reflective coating. Correspondingly, the material, and thus the material properties, of the lens can be selected to refract (i.e., bend), or reflect incoming light in the manner required by a specific application.
[0092] In some cases, a lens can define multiple individual lens elements or wave guides to help achieve a desired output characteristic. That is, a lens can include different sections or structural features that are configured to cooperate with one another to provide a desired output. For example, a lens can include a plurality of lens elements, which can be configured as areas of localized curvature (e.g., flat, convex, or concave curvature) or other geometries (e.g., ridges, flutes, etc.), or distinct structures (e.g., separate lenses, prisms, or other structures) configured to operate in conjunction with one another to achieve the desired output, for example, a tinted lens element and a columnating or diffusing lens element. In particular, tinting a lens can provide for an increased color gamut, which may not be possible with lighting elements alone. For example, a lens can have a purple tint to achieve a desired hue with a white light emitting lighting element.
[0093] As previously mentioned, the safety light can be configured to receive an emission of light from a lighting assembly to selectively provide a first, 360-degree emission of light, as well as a second emission of light configured as a beam. Accordingly, in some cases, a lens structure of a safety light can have different lenses (e.g., lens portions or elements configured for each type of emission). Correspondingly, each of the lens portions may also be made from one or more lens elements, reflectors, or other optical components that are configured and arranged to provide a desired emission of light. The various lenses, including any optical components, can be separately formed, or integrally formed as part of a monolithic lens structure.
[0094] As shown in FIGS. 12 and 13, in the illustrated non-limiting example, the lens structure 104 is configured as a monolithic lens that includes a peripheral lens 1208 (e.g., a primary lens) configured to emit light 360 degrees around the safety light 100 and a beam lens 1212 (e.g., a secondary lens) configured to emit light in a beam light pattern. Accordingly, the beam lens 1212) can be formed as a protrusion on the peripheral lens 1208 In other examples, the lens may be a segmented lens, which is made up of a plurality of lens components to create the lens structure 104. The peripheral lens 1208 can be configured to provide a diffuse emission of light that is visible around an entire periphery of the safety light 100 (e.g., by diffusing anemission of light from a lighting element). Put another way, the peripheral lens 1208 can be configured to receive an emission of light from one or more lighting elements to produce an omnidirectional light. Accordingly, the peripheral lens 1208 can extend along each of the third side 217, fourth side 222, fifth side 604, and sixth side 704 to form at least a portion of the periphery of the housing 117 along each side. In the illustrated embodiment, the peripheral lens 1208 extends continuously along each of the fourth side 222, fifth side 604, and sixth side 704, and partially along the third side 217 (e.g., discontinuously) to accommodate the beam lens 1212.
[0095] Continuing, the beam lens 1212 can be integrally formed with the peripheral lens 1208 along the third side 217. The beam lens 1212 is a region of lens structure 104 that is configured to receive light emitted by a lighting element and to produce a directional beam of light. A beam produced by the beam lens can be a columnated, conical, or other shaped beam of light that is emitted along an emission axis that is oriented along a particular direction. In the illustrated non-limiting example, the beam lens 1212 is positioned to emit a beam of light along a beam axis (e.g., an emission axis) oriented along the 360-degree emission of the peripheral lens 1208. That is, the peripheral lens 1208 can produce a 360-degree emission of light that extends outwardly from the housing 117 along an emission plane 1210, and the beam lens 1212 can produce a beam with an emission axis 1214 that extends along and within the emission plane (see FIG. 13). In other non-limiting examples, the beam emission can be parallel to and offset from the emission plane 1210, or at a non-zero angle relative to the emission plane 1210 (e.g., to be normal to or at an oblique angle relative to the emission plane). The particular direction of the beam emission can be selected in accordance with a particular use of the light. For example, the beam emission can be along the emission plane for wearing on a shoulder of a user, or normal to or oblique to the emission plane for use as a headlamp (e.g., out of the second cover 112).
[0096] A beam lens can have a variety of shapes to produce a beam light with the desired qualities (e.g., a shape or beam pattern, intensity, beam angle, etc.). In the illustrated nonlimiting example, the beam lens 1212 is cylindrically shaped and includes a diameter and / or thickness that is larger than a thickness of the peripheral lens 1208 (e.g., a dimension of the peripheral lens 1208 extending between the first cover 108 and the second cover 112). Put differently, the beam lens 1212 may be dimensionally larger than the peripheral lens 1208, such that the beam lens 1212 extends above and below the peripheral lens 1208. Similarly, the beam lens 1212 may form a local protrusion that extends outwardly from the peripheral lens 1208. Accordingly, while the peripheral lens 1208 can be approximately flush with the perimeter ofthe safety light 100 as defined by the first cover 108 and the second cover 112, the beam lens 1212 may protrude away from the peripheral lens 1208, the first cover 108, and the second cover 112. The beam lens 1212 may extend outwardly in order to provide space for one or more optical components that can be configured to reflect and / or guide light in the desired beam pattern.
[0097] In general, a beam lens can include one or more optical components to help shape the beam of light. For example, as shown in FIG. 14, the beam lens 1212 defines a hollowed interior space 1304 having an interior surface 1404 that is shaped to guide the light from a lighting element into the desired beam shape. In the illustrated non-limiting example, the inner surface 1404 has a conical shape with a diameter that increases moving outwardly from the interior of the housing 117 to the exterior of the housing 117. The conical shape can define an axis 1214 that may be coincident with the desired emission axis. In some cases, the interior surface 1404 can have a reflective coating, or it can be arranged in such a manner to cause total internal reflection of light off of the interior surface 1404.
[0098] In other cases, a beam lens can be configured to receive a separate optical component to guide an emission of light and produce the desired beam shape. For example, in the illustrated non-limiting example, interior surface 1404 is defined by a reflector 928 that is received within interior space 1304. The reflector 928 may define a frustoconical, parabolic, or other shape, which in turn can define the interior surface 1404. Accordingly, the interior space 1304 is shaped to receive the reflector 928. In other non-limiting examples, the interior surface of the beam lens 1212 can be monolithically formed with the beam lens 1212. Correspondingly, the interior surface 1404 can have a reflective coating, or it can be arranged in such a manner to cause total internal reflection of light off of the interior surface 1404. In other non-limiting examples, a beam lens can be configured differently to produce the desired output.
[0099] In some cases, a cover can be provided around a protrusion formed by a beam lens to provide additional protection to the beam lens. For example, in the illustrated embodiment the safety light 100 includes bezel 932 (see e.g., FIG. 9) configured to protect and / or cover the beam lens 1212. The bezel 932 may extend from the first cover 108 to the second cover 112 to help reduce scratching and / or damage to the beam lens 1212. The bezel 932 can be secured to one or both of the first cover 108, the second cover 112, and the lens 104. In some cases, the bezel 932 may be made from an opaque, non-light transmissive material, which can help to prevent light from exiting the sides of the beam lens 1212 and increase the beam intensity. Correspondingly, in some cases and interior surface of a bezel can be configured as a reflective surface to further improve light transmission through a beam lens.
[0100] In some non-limiting examples, a lens structure can include light guiding or collecting structures to help collect light from a corresponding plurality of lighting elements, thereby improving the efficient of light transfer between the plurality of lighting elements and the lens. That is, such collecting structures increase the percentage of emitted light that passes through the lens. Such light collecting structures can be provided on a light entering surface of a lens. For example, a top surface or other light entering surface can, define guides or seats that can help guide and collect light from a lighting assembly. Such light collecting structures can be provided as separate structures apart or they may be integrally formed with a lens or lens element. In some cases, there can be a one-to-one correspondence between a light collecting structure of the lens and the lighting elements of the plurality of lighting elements. However, a light collecting structure may also be configured to correspond with more than one lighting element.
[0101] The seats can reduce the gap between a lighting element and a lens (e.g., a lens element). That is, any air that may be disposed between a lighting element and a lens, which can attenuate and dissipate light emitted by the lighting element, can be reduced. Additionally, some seats can be shaped to partially of fully surround a lighting element to help capture light. In that regard, a seat can include peripheral walls that can help to prevent light from traveling away from a lens. In some cases, such peripheral walls may be configured to reflect light back toward a lens. As a result, light can be more efficiently transferred to and collected by a lens. As a result, the safety light can produce more intense or powerful light, which aids in improving visibility over long distances.
[0102] For example, with additional refence to FIGS. 11 and 12, the peripheral lens 1208 can define a plurality of seats 1236 (e.g., raised, or indented seats) that correspond with individual lighting elements or groups of lighting elements of the lighting assembly. The seats 408 can reduce the gap between a lighting element and a lens (e.g., a lens element). That is, an amount of air that may be disposed between a lighting element and a lens, which can attenuate and dissipate light emitted by the lighting element, can be reduced. Additionally, seats can be shaped to partially or fully surround a lighting element to help capture light (e.g., so as to at least partially receive a lighting element therein). In that regard, a seat can be a recessed seat that can include peripheral walls that can at least partially surround a lighting element to help to prevent light from traveling away from a lens. In some cases, such peripheral walls may be configured to reflect light back toward a lens. As a result, light can be more efficiently transferred to and collected by a lens. Correspondingly, the safety light can produce more intense or powerful light, which aids in improving visibility over long distances.
[0103] In the illustrated non-limiting example, each of the seats 1236 is configured as a recess that extends into an interior surface of the peripheral lens 1208 to receive a lighting element. Here, the seats have a generally cylindrical shape, although other shapes are possible to produce a desired emission characteristic. For example, while a bottom surface 1237 of each of the seats 1236 is a generally planar surface, in other non-limiting examples, the bottom surface 1237 can be a curved surface that can help to distribute light in the desired pattern. To that end, while the seats 1236 are integrally formed with peripheral lens 1208, in other nonlimiting examples seats can be configured to retain other optical components. For example, in some cases, a seat can be configured to retain a lens element (e.g., a separate lens configured to capture or otherwise guide light from a particular lighting element or group of lighting elements).
[0104] Correspondingly, a beam lens can also define a seat to receive one or more lighting elements. In the illustrated non-limiting example, the reflector 928 defines a reflector seat 1704 (shown in FIGS. 17 and 18) that is configured to receive a lighting element. The reflector seat 1704 is formed as hole in the reflector 928 to allow the lighting element to be positioned within the interior space 1304. In this way the lighting element can be positioned at a desired position relative to any optical features to produce the desired output (e.g., to be at a focal point of a reflector or lens element). In other non-limiting examples seats can be configured in other ways according to the specific construction of the lens and any optical components thereof.
[0105] Continuing, and as generally discussed above, lighting assemblies can include one or more lighting elements that can be configured to emit light in a desired direction, for example, towards a lens or a light collecting structure of a lens. For example, a lighting element may not produce a columnated beam, but rather a diffuse emission of light. Accordingly, a reflector, for example a flat, spherical, or parabolic reflector, may be provided around the lighting element to guide light in a specific direction and / or to change a beam pattern produced by a lighting element. Such reflectors can, for example, produce columnated light, reduce diffusion, or focus light produced by the lighting element. In some cases, there can be a one- to-one correspondence between a reflector and the lighting elements of the plurality of lighting elements. However, a reflector may also be configured to correspond with more than one lighting elements. Additionally, reflectors can be configured in a variety of shapes to achieve the desired output characteristics, for example, square, rectangular, round, ellipsoidal, and other polygonal or non-polygonal shapes. A reflector can be configured to work in conjunction with a light collecting element to further improve transfer efficient of light between a lighting element and a lens. For example, an outer perimeter of a reflector may have a shape whichcorresponds with a light collecting structure, and vice versa, to reduce the amount of light that travels away from a lens. In that regard, a reflector can be received in a recessed portion of a light collecting structure.
[0106] As can be seen in FIG. 11, a lighting assembly can include a plurality of lighting elements 1104 arranged relative to the lens structure 104 to emit light from the safety light 100. Here the lighting elements are configured as LEDs; however, other types of lighting elements are also possible. In one example, the lighting elements 1104 can be controlled by the circuit board 908 via the button layer 904, or another type of user interface, and are powered via the battery 912. Each lighting element 1104 may nest within a seat 1108 integrally formed within the lens structure 104. The seat 1108 may be configured to direct light emitted by the lighting element 1104 outward from the safety light 100. For example, the seat 1108 may direct light emitted by the lighting element 1104 in a variety of light patterns, such as a diffuse pattern, beam pattern, and / or a combination of light patterns.
[0107] FIGS. 12 and 13 show examples of a lighting assembly 1002 of the safety light 100. The lighting assembly 1002 includes the one or more lighting elements 1104, which can be mounted in various ways in order to achieve the desired light output from the lens structure 104. For example, in some cases, lighting elements can be secured directly to a circuit board. In other cases, lighting elements can be secured indirectly to a circuit board (e.g., a first or primary circuit board). For example, as illustrated in FIGS. 12 and 13, the light elements 1104 can be mounted on one or more mounting boards, which, in the illustrated non-limiting example, are configured as one or more dropdown boards 916 (e.g., a second board). The dropdown boards 916 may include one or more first LED boards 920 and one or more second LED boards 924 (shown in FIG. 9). The first LED boards 920 may include a single LED and / or chip on the board, while the second LED boards 924 may include multiple (e.g., more than one) LED and / or chip on the board. The dropdown boards 916 can form part of the lighting assembly 1002.
[0108] Each of the dropdown boards 916 (e.g., the first LED boards 920 and the second LED boards 924) include a slot 1204. The slots 1204 are configured to connect the dropdown boards 916 to the circuit board 908 via an electrical connection. For example, a protrusion 1904 (shown in FIG. 19) extending from the circuit board 908 is configured to mate with and / or interference fit within the slots 1204 of the dropdown boards 916 to form a connection between the circuit board 908 and the dropdown boards 916. In one example, the LED boards and the circuit board connect via the protrusion and slot to form a roughly 90-degree angle between the LED boards and the circuit board, such that the LED board runs sufficiently parallel to thelens. Furthermore, the LED boards are typically positioned adjacent the lens, between the lens and one or more other components of the safety light, such as the circuit board, battery, etc.
[0109] Referring to FIG. 9, and as generally described above, lighting elements can be operated in various combinations to produce a desired emission of light. For example, the lighting elements 1104 can include a beam lighting element 1106 that is configured to produce a directional beam emission from the beam lens 1212. Here, the beam lighting element 1106 is a single lighting element, but it can also be made of multiple lighting elements. Additionally, the plurality of lighting elements 1104 includes a plurality of peripheral lighting elements 1114 (e.g., the remaining lighting elements on the dropdown boards 916) that are configured to collectively produce the 360-degree emission of light from the peripheral lens 1208. The beam lighting element 1106 and the plurality of peripheral lighting elements 1118 can be operated simultaneously and separately. Further, a work light element 1110 can be coupled to the circuit board 908 to emit light through the secondary lens 116 and out the second cover 112.
[0110] Correspondingly, lighting elements can also be operated in other groupings. For example, the plurality of peripheral lighting elements 1114 can include a first plurality of peripheral lighting elements 1114a and a second plurality of peripheral lighting elements 1114b. The first plurality of peripheral lighting elements 1114a and the second plurality of peripheral lighting elements 1114b each emit light along a portion of the periphery of the safety light 100. In this case, each of the first plurality of peripheral lighting elements 1114a and the second plurality of peripheral lighting elements 1114b is configured to produce a 180-degree emission to collectively produce the 360-degree emission. In other examples, lighting elements can be grouped differently.[OHl] As illustrated in FIGS. 14 and 15, the lens structure 104 may include a first ridge 1420 and a second ridge 1408 extending around a perimeter of the lens structure 104. The first ridge 1420 and the second ridge 1408 are configured to engage with and / or slot within a first channel 1412 and a second channel 1416 of the second cover 112 and the first cover 108, respectively. As shown in FIG. 15, the first channel 1412 extends around the perimeter and / or outer periphery of an interior side of the second cover 112, which is similar to how the second channel 1416 extends around the perimeter and / or outer periphery of an interior side of the first cover 108. As should be appreciated, a seal formed between the first ridge 1420 and the first channel 1412 and the second ridge 1408 and the second channel 1416 similarly extends around the entire perimeter of the safety light 100. Thus, the safety light 100 can be sufficiently waterproof and / or water resistant via the seal between the lens structure 104 and both the first cover 108 and the second cover 112 via the first ridge 1420 and the second ridge 1408.- 1 -Similarly, the safety light 100 can withstand extreme temperatures, pressures, elements, and / or other extreme conditions without a loss in functionality. In some cases, a sealing element, for example, an O-ring or gasket (e.g., the button layer 904) can be secured within the channel to further effect sealing between the lens structure 104 and each of the first cover 110 and the second cover 112. The sealing element may be made from a flexible, temperature resistant, rubber and / or polymeric material.
[0112] In some examples, the safety light may include alternative and / or additional lens variations configured to produce different, adjustable, and / or additional light beams. In one example, the safety light may include more than one beam lens, such as two, three, and / or more beam lenses on the same and / or different sides of the lens. As should be appreciated, the use of multiple beam lenses may allow for concentrated beam light patterns in a plurality of directions simultaneously. In another example, the use of multiple beam lenses may allow for an increase in the total beam intensity / brightness (e.g., lumens) by utilizing more than one beam lens on the same side of the safety light.
[0113] FIGS. 20 and 21 show an example of a safety light 2000 with more than one beam lens 1212. In particular, the safety light 2000 includes two beam lenses 1212A, 1212B arranged on opposite sides of the lens structure 104 (e.g., a third side 217 and a fourth side 222). In other examples, the safety light may include more than two beam lenses, such as three, four, and / or more beam lenses arranged around the outer periphery of the lens structure 104 (e.g., on a third side, 217, fourth side 222, fifth side 604, and / or sixth side 704). With multiple beam lenses arranged around the lens structure 104 the safety light 2000 may provide a multi-directional beam illumination in addition to the 360-degree illumination provided via the peripheral lens 1208 in multiple directions simultaneously.
[0114] FIGS. 22 and 23 show another example of a safety light 2200 with more than one beam lens 1212. The safety light 2200 includes two beam lenses 1212A, 1212B arranged on the same side of the lens structure 104 (e.g., both on a third side 217). As should be appreciated, the beam lenses may be powered separately or simultaneously to enable a user to emit more light (e.g., a greater number of lumens) to illuminate the surroundings. In other examples, multiple beam lenses may be disposed on a single side of the lens structure 104 while further beam lenses are disposed on other sides of the lens structure in addition to the peripheral lens.
[0115] In some examples, the safety light may include a removable bezel assembly. The bezel assembly may include an integral reflector, which is held within the bezel assembly. The bezel assembly may be selectively attached and / or detached from the lens to enable modification in the beam pattern emitted from the lens (e.g., to provide for multiple beamangles). For example, the bezel assembly may be added to the lens to provide a more concentrated beam pattern having a first beam angle. Alternatively, the bezel assembly may be removed from the lens to provide a more diffuse beam pattern having a second beam angle that is different from the first beam angle. Correspondingly, different bezels can be attached to provide for other beam angles, or to change another property of an emission of light (e.g., a color thereof)
[0116] The bezel assembly may fit within a cutout or pedestal defined by the lens. In one example, the bezel assembly is held within the cutout via friction and / or interference fit. In another example, the bezel assembly is held within the cutout via a threaded connection between the bezel assembly and the sidewalls of the cutout. In yet another example, the bezel assembly is held within the cutout via a magnetic connection. In some embodiments, the bezel assembly is rotatably held within the lens, such that a bezel of the assembly may be rotated to adjust a beam pattern of the emitted light.
[0117] FIG. 24 shows an example of a safety light 2400 with a removable bezel assembly 2428. The safety light 2400 may include a lens 2404 defining a central cutout 2408. The cutout may include a closed back 2412, which prevents debris and / or liquid from passing into an interior of the safety light 2400. In one example, a lighting element 2416 is positioned in the center of the cutout 2408 and is configured to emit light through the bezel assembly 2428. The bezel assembly 2428 includes a bezel 2424 and a reflector 2432 integrally formed with or coupled to the bezel 2424. As mentioned previously, the bezel assembly 2428 may be removable from the lens 2404. For example, the bezel assembly 2428 is configured to magnetically connect to the lens 2404 within the cutout 2408. In one example, the cutout 2408 includes a peripheral sidewall 2420, which may include one or more magnets or a magnetic material configured to interact with one or more magnets and / or a magnetic material within the bezel 2424. Accordingly, the removable bezel assembly 2428 may be removed from the lens 2404 via force applied in the direction shown by arrow 2508 (e.g., pulling the bezel assembly out of the cutout). Thus, a user may selectively add and / or remove the bezel assembly 2428 from the lens 2404. In other examples, the bezel assembly 2428 may be mounted to the lens 2404 in other ways, such as a threaded connection, snap-fit, interference fit, and / or any other method.
[0118] In some examples, such as is shown in FIGS. 25 and 26, the removable bezel assembly 2428 may be rotatable within the cutout 2408. As mentioned previously, rotation of the bezel assembly 2428 may affect the beam pattern of light passing through the reflector 2432. For example, rotation of the bezel assembly may adjust or modify the reflection of lightwithin the reflector to change a beam angle and provide a more concentrated or diffuse beam pattern. To that end, the bezel assembly 2428 can provide for multiple discrete beam angles, or may be continuously variable between a maximum beam angle and a minimum beam angle.
[0119] To adjust the beam pattern of the light the bezel assembly 2428 can be rotated in the direction shown by arrows 2504. In other examples, rotation of the bezel assembly 2428 can adjust a spacing between the lighting element and the reflector, which can change the beam pattern being emitted. As can be seen in FIG. 25, in some examples, the lighting element 2416 (shown in FIG. 24) may be positioned behind the back 2412 of the cutout 2408. Thus, the lighting element 2416 can be protected from debris and / or liquid, which may extend the useful life of the lighting element. In other examples, the cutout 2408 may not include a wall 2412 (shown in FIG. 24) and may instead define an opening, which is filled by the bezel assembly 2428. In some examples, the bezel assembly 2428 may include a removable gasket circumferentially disposed around the bezel. The gasket is configured to form a seal between the bezel and the lens, such that debris and / or liquid cannot penetrate the interior of the safety light.
[0120] In some examples, the beam lens may be a variety of different shapes and / or sizes to enable a user to select a desired beam pattern (e.g., rectangular beam pattern, circular beam pattern, concentrated beam pattern, diffuse beam pattern). In some examples, the safety light may include multiple different beam lenses configured to generate a variety of beam patterns.
[0121] FIG. 27 shows an example of a safety light 2700 with a lens structure 2704 having a beam lens 2708 with a dome shape (e.g., a hemispherical shape). The dome shape of the beam lens 2708 may be configured to emit a more diffuse light pattern, as compared with the beam lens described previously. FIG. 28 shows an example of a safety light 2800 with a lens structure 2804 having a beam lens 2808 with a cylindrical shape. The cylindrical beam lens 2808 may be configured to emit a directional beam that is more diffuse in a first direction than in a second direction. FIG. 29 shows an example of a safety light 2900 with a lens structure 2904 having a beam lens 2908 with a rectangular shape. The beam lens 2908 may be configured to emit light in a rectangular beam pattern 2912. In other examples, the safety light 2900 may have a differently shaped beam lens to produce a differently shaped beam.
[0122] In some examples, the safety light may have more than one beam lens, which can be positioned perpendicular to the peripheral lens. As should be appreciated, this configuration may enable a user to emit columnated light both outward from the safety light and / or downward / upward from the first and / or second cover of the safety light.
[0123] FIGS. 30 and 31 show examples of a safety light 3000 with a modified second cover 3004 including a perpendicular beam lens 3008. The beam lens 3008 may be positioned perpendicular to the beam lens 1212. In one example, the beam lens 3008 is incorporated into a lens cover 3104, which is formed as a part of lens structure 104. For example, the lens structure 104 and the lens cover 3104 form a monolithic lens structure. In other embodiments the lens structure 104 and the lens cover 3104 can be separate components.
[0124] Similarly, FIG. 32 shows a safety light 3200 with the beam lens 3008 positioned on the second cover 3004, perpendicular to a lens 3204. The lens 3204 of the safety light 3200 includes the peripheral lens 1208 to provide a 360-degree emission, as well as a second, domeshaped beam lens 3208 to provide a directional beam along the 360-degree emission. Also, FIGS. 33 and 34 show another example of a safety light 3300 with a lens 3304 having a beam lens 3008 positioned on the second cover 3004 to emit a directional beam perpendicular to the 360-degree emission. The lens 3304 does not include a beam lens arranged to emit a directional beam along the 360-degree emission.
[0125] In some examples, the safety light may include one or more downward-firing lighting elements, which can, for example, emit light toward a cover rather than directly out of a lens. Correspondingly, downward-firing lighting elements may be used with an angled reflector, which can reflect light emitted by the downward-firing lighting element outward from the lens. In one example, the angled reflector may have an angle of between 30 and 60 degrees. In another example, the angled reflector may have an angle of 45 degrees.
[0126] FIGS. 35-37 show examples of a safety light 3500 with a lens structure 3504 for use with one or more downward firing lighting elements 3708. The lens structure 3504 includes a smooth, unbroken, peripheral surface 3604 configured to emit light omnidirectionally (e.g., 360 degrees) around the safety light 3500. The lens structure 3504 further includes a top surface 3608 configured to collect light from the one or more downward firing lighting elements 3708. In use, the lighting elements 3708 emit light downward, perpendicular to peripheral surface 3604, and through the top surface 3608. The light then reflects off of an angled reflector 3612 molded and / or positioned within the lens structure. The angled reflector 3612 is configured to reflect the light outward (e.g., along axis 1214), around the periphery of the safety light 3500.
[0127] In some examples, the safety light 3500 may further include a beam lens 2708 configured to further concentrate the reflected light into a beam pattern. As should be appreciated, the safety light 3500 may include the angled reflector 3612 around the entire periphery of the lens structure 3504 (e.g., for both the peripheral and beam lens portions) and / or around only a portion of the lens structure 3504 (e.g., only the beam portion or only theperipheral portion). For example, the safety light 3500 may include the angled reflector 3612 adjacent a beam lighting element and / or beam lens 2708. Alternatively, or additionally, the safety light 3500 may include the angled reflector 3612 around the peripheral lens and not the beam lighting element. For example, as shown in FIG. 38, the safety light 3500 may include the angled reflector 3612 around the peripheral lens but include a circuit board 908 with a dropdown board 916 including a lighting element 1104. The lighting element 1104 may emit light through the beam lens 2708 (e.g., along axis 1214) via the conical and / or frustoconical reflector 928.
[0128] In some examples, a user may desire a safety light with a plurality of beam lenses configured to produce a plurality of concentrated light beams. In one example, to power one or more high powered lighting elements an external power source is plugged in to the safety light. To provide a more concentrated light pattern one or more beam lenses, such as dome lenses may be disposed around the entire outer periphery of the lens.
[0129] FIGS. 39 and 40 show a safety light 3900 including a lens structure 3904 with a plurality of beam lenses 4004 around a periphery of the lens structure 3904 to collectively provide a 360-degree emission of light. The lens structure 3904 may further include a directional beam lens 4008 having a different beam pattern from the beam lenses 4004 (e.g., a with a different beam angle or intensity). In one example, the beam lenses 4004 and / or the beam lens 4008 may be dome type lenses. In other examples, the beam lenses 4004 or 4008 may be rectangular, cylindrical, and / or other shape lenses. In some cases, the lens structure 3904 may further include another beam lens 3008 integrated into the lens cover 3104. Correspondingly, lighting elements can be configured to emit light through each of the lenses 4004, 4008, and / or 3008.
[0130] As can be seen in FIG. 41, the safety light 3900 may include multiple variations and / or styles incorporating any of the lens shapes and / or types described previously. For example, the safety light 3900 may include a secondary, dome-shaped beam lens 116 configured to emit light from the second cover 112. In one example, the lenses 4004 may extend around the entire outer periphery of the lens structure 3904. In other examples, the lenses 4004 may extend around only a portion of the outer periphery of the lens structure 3904, such as a single side, two sides, three sides, and / or four sides of the lens structure 3904.
[0131] In some examples, a user may desire a safety light without any physical buttons and / or controls thereon. For example, a user may not want any buttons and / or controls that may be inadvertently bumped and / or turned on, which may reduce battery life. Thus, in some cases, it can be beneficial for a safety light to be remotely controlled, for example, via a mobile deviceand / or remote controller. As one particular example, a safety light may be controlled via a mobile application (App) on a mobile phone to turn on / off the device, adjust brightness levels, monitor battery life, adjust beam patterns and / or other functions. The safety light 4200 may also be controlled remotely via another type of electronic device, such as a mobile device, remote control, remote server, computer, and / or other device. In one example, the safety light 4200 can be connected to the electronic device via a short-range wireless connection, such as Bluetooth and / or Wi-Fi. In another example, the safety light 4200 is connected to the electronic device via radio frequency (RF) communications.
[0132] FIG. 42 shows an example of a safety light 4200 without any buttons. The safety light 4200 includes a second cover 4204 that is free from any buttons and / or controls that may be inadvertently actuated (e.g., turned on / off) by a user. Additionally, the lack of buttons and / or holes in the second cover 4204 may enable the safety light 4200 to be hermetically sealed to prevent fluid flow into the safety light. Thus, the safety light 4200 may be used in underwater and / or in other harsh environmental conditions.
[0133] FIGS. 43-55 illustrate another example of a safety light 4300. As will be recognized, the safety light 4300 shares a number of components in common with and operates in a similar fashion to the examples illustrated and described previously. For the sake of brevity, these common features will not be again described below in detail. Rather, previous discussion of commonly named or numbered features, unless otherwise indicated, also applies to example configurations of the safety light 4300.
[0134] With particular reference to FIG. 46, a button layer 4404 of the safety light 4300 may include one or more rings 4608 (e.g., rings made from a resilient material) surrounding each of the buttons 120. In one example, the rings 4608 may be integrated into the button layer 4404 to provide additional seal force between the button layer 4404 and a second cover 4312. For example, additional seal force may be generated via compression of the rings 4608 by the second cover 4312 when the safety light 4300 is assembled. The additional seal force may mitigate the ingress of debris and / or liquid entering into the interior space 1112 of the safety light 4300. In other non-limiting examples, buttons can be provided separately from one another (e.g., not integrated into a button layer 4404).
[0135] The button layer 4404 may further include a sidewall 4602 that defines a periphery around the button layer 4404 to create an internal recess 4604 within the button layer 4404. In one example, the internal recess 4604 may receive a portion of a circuit board (e.g., the circuit board 908 or circuit board 4408) so that the button layer 4044 is securely retained around the perimeter of the circuit board 908 via the sidewall 4602 of the button layer 904. The sidewall4602 can also improve sealing between a lens 4304 and the housing 117 (e.g., the cover 4312). In some examples, the sidewall 4602 can be configured to accommodate a connection port (e.g., a charging or data port, such as port 124) for the safety light 4300. In the illustrated example, the sidewall 4602 includes a flange 4606 to accommodate a connection port. In addition, the sidewall 4602 can be contoured to seal around a beam lens 5012 (see FIG. 50). For example, the sidewall 4602 includes a second flange 4610 to accommodate the beam lens 5012.
[0136] Turning now to FIGS. 47 and 48, in one particular example, to facilitate wireless charging of the safety light 4300, a cable 4415 (e.g., an induction coil) may be arranged within the housing 117 (e.g., within a first cover 4308. The cable 4415 can generate an electrical current in response to a changing magnetic field (e.g., from a charger) that is used to recharge the battery 4412. In the illustrated example, the cable 4415 is positioned circumferentially around the magnet tray 304 and the magnet 936. In one example, the cable 4415 may include a circular portion 4706 that may be arranged around (e.g., circumferentially around) the magnet tray 304 via the inserts 312, or by being positioned with a recess (e.g., a recessed region surrounding the magnet tray 304). Extending from the circular portion 4706 may be a cable body 4708, which may extend from the circular portion 4706 to the battery 912 via the circuit board 908 (e.g., a controller secured thereon). Thus, when the safety light 4300 is arranged on a wireless charger, energy (e.g., electrical energy) may flow from the charger through the cable 4415 and into the battery 912 to facilitate charging (e.g., inductive charging) of the battery. In the illustrated example, a single coil is provided. In other examples, multiple coils may be provided. Additionally, the shape of the coil may vary, for example, to be a rectangular shape. In one example, to provide additional structural (e.g., crush) strength to the safety light 4300, the first cover 4308 may include one or more pillars 4704 extending away from an interior surface 4702 (e.g., a recessed portion 4720) of the first cover 4308. Correspondingly, the second cover 4312 may include one or more pedestals 4804, which may extend from an interior surface 4802 of the second cover 4320 towards the first cover 4308. Thus, the pillars 4704 and the pedestals 4804 may provide additional structural integrity to the safety light 4300. In one particular example, a fastener may protrude through the pillars 4704 into the pedestals 4804 to secure the first cover 4308 to the second cover 4312 (e.g., to form the safety light 4300).
[0137] FIG. 49 shows one example of a circuit board 4408 for use with the safety light 4300. The circuit board 4408 may include one more tactile elements 4902, which may provide enhanced button feedback or tactile feel to an operator. In one particular example, the tactile elements 4902 may be in the form of “snap domes.” In some examples, the tactile elements4902 may be positioned between the button layer 4404 and the circuit board 4408. As mentioned above, the tactile elements 4902 may provide an enhanced tactile feel to the buttons 120 during actuation, which may provide a user with audible or tactile indication of a button press. In one example, each of the buttons 120 may include a tactile element 4902 positioned between the button layer 4404 and the circuit board 4408. However, in other examples, only some of the buttons may include a tactile element 4902.
[0138] The tactile elements 4902 may each define a domed (e.g., arcuate) shape with an apex 4904 of the tactile element 4902 contacting the button (e.g., a button 120). However, during actuation of the button, the button may contact the apex 4904 and deform (e.g., flatten) the tactile element 4902, which may provide tactile or audible feedback to a user.
[0139] Further, during actuation (e.g., pressing) of the one or more buttons 120, the actuated button contacts the tactile element 4902 (e.g., the tactile element positioned under the actuated button), which resiliently deforms the tactile element 4902. As a result of deformation of the tactile element 4902, the tactile element 4902 contacts the circuit board 4408 (e.g., at a capacitive contact), creating an electrical connection between the button layer 4404 and the circuit board 4408. When pressure on the button is released, the tactile element 4902 will automatically reattain its initial, undeformed shape, thereby breaking contact with the circuit board 4408.
[0140] FIGS. 50-53 illustrate an example of a lens assembly 5000 of the safety light 4300. In one example, the lens assembly 5000 may include one or more dropdown boards 4416, which may be secured together to form a substantially tubular periphery of the safety light 4300. In one particular example, the dropdown boards 4416 may include a first side 5002, a second side 5004, a third side 5006, and a fourth side 5008. Further, each of the sides of the dropdown boards 4416 may include one or more columns 5304 of lighting elements 5306. For example, the dropdown boards 4416 may include columns having vertically stacked pairs of lighting elements 5306, which may include the first lighting element 5306 and a second lighting element 5308.
[0141] Correspondingly, a lens 4304 may include a diffuse lens 5010 (e.g., a peripheral lens) and a beam lens 5012. However, the lens 4304 may not include any of the seats 1108, unlike the lens 104 described previously. Instead, the lens 4304 may include a substantially flat inner surface 5102.
[0142] With particular reference to FIG. 52, the beam lens 5012 may include a bezel 4432. In one example, the beam lens 5012 may include a pair of vertically spaced protrusions 5202configured to engage with corresponding channels 5204 of the bezel 4432 to limit rotation of the bezel 4432.
[0143] During operation of a safety light, heat can be generated by a variety of components, including a power source, processer, lighting elements, etc. Typically, as light output increases, so does the heat generated by the safety light. The heat generated by the safety light can be dissipated to the surrounding environment to ensure optimal light performance. To improve heat dissipation, a safety light can include a heat sink to collect and dissipate heat. For example, a dedicated heat sink can be provided, or a housing cover can be configured to function as a heat sink.
[0144] In one particular example, a battery 4412 may include a metallic housing 5504 (e.g., an exterior metallic surface), which may permit efficient heat transfer away from the battery 4412. For example, the metallic housing 5504 may transfer heat from the battery 4412 to a heat sink 4425 within the safety light 4300. The heat sink 4425 may be positioned within an interior cavity 5400 of the safety light 4300, between the circuit board 4408 and the first cover 4308. In one example, the heat sink 4425 may include a cutout 5408 shaped to receive and secure the battery 4412 therein. Thus, the battery 4412 may be partially encapsulated within the cutout 5408, in direct contact with the heat sink 4425, so that heat is transferred through the heat sink 4425 away from the battery 4412.
[0145] In one particular example, the heat sink 4425 may include a series of ridges 5406 along opposing sidewalls 5402 of the heat sink 4425. The sidewalls 5402 may wrap around opposing sides of the battery 4412, so that heat from the battery 4412 is dissipated through the heat sink 4425 (e.g., via the ridges 5406). Further, a base 5404 of the heat sink 4425 extending between the sidewalls 5402 may be in direct contact with the first cover 4308 and the magnet 936, which may permit heat transfer from the heat sink 4425 to the first cover 4308 and / or magnet. Put differently, the heat sink 4425 (e.g., the base 5404 of the heat sink 4425) may be positioned between the battery 4412 and the first cover 4308, so that heat may flow from the battery into the heat sink 4425 and dissipate (e.g., via convection and / or conduction) through the first cover 4408 and / or magnet. As should be appreciated, in some examples, the heat sink 4425 may be integrated into the housing of the battery 4412 as an assembly. Further, the heat sink 4425 may be made from a highly-conductive material, such as a metallic material (e.g., aluminum, copper, titanium, etc.) to permit efficient heat transfer.
[0146] Additionally, heat generated by the one or more lighting elements arranged on the dropdown boards 4416 may flow from the dropdown boards 4416 into the sidewalls 5402 ofthe heat sink 4425 and then through the base 5404 of the heat sink 4425 and away from the safety light 4300 through the first cover 4308 and / or the battery 936.
[0147] The safety lights, as generally described above may include any combination of the alternative lens structures described herein depending on the needs of a user. As should be appreciated, the safety lights discussed previously may each be connected to an electronic device as well. Thus, the safety lights may be controlled via the one or more buttons and / or the electronic device.
[0148] As used in the claims, the phrase "at least one of A, B, and C" means at least one of A, at least one of B, and / or at least one of C, or any one of A, B, or C or combination of A, B, or C. A, B, and C are elements of a list, and A, B, and C may be anything contained in the Specification.
[0149] The present invention has been described in terms of one or more preferred embodiments, and it should be appreciated that many equivalents, alternatives, variations, and modifications, aside from those expressly stated, are possible and within the scope of the invention.
