SYSTEMS AND METHODS FOR EXTERNAL REFLECTORS FOR PORTABLE,SAFETY LIGHTINGCROSS-REFERNCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 751,523, filed January 30, 2025, which is incorporated herein by reference in its entirety for any and all purposes.BACKGROUND

[0002] The present disclosure relates generally to safety lighting systems and methods. More specifically, the present disclosure relates to systems and methods for external reflectors for safety lighting, for example, which can be visible from at least 360-degrees around a particular location, or other features.SUMMARY

[0003] 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. An external reflector can be coupled to the housing of the safety light to redirect a portion of the light emitted from the safety light in a desired direction.

[0004] According to one aspect of the present disclosure, a light system can include a first cover and a second cover. A peripheral lens can be positioned between the first cover and the second cover to define a periphery of the lighting system. The peripheral lens can be configured to direct an emission of light along an emission plane to be visible 360-degrees about the light system. A lighting assembly can emit light through the peripheral lens. A reflector can be coupled to the first cover and can be configured to direct a portion of the emission of light emitted from the peripheral lens at a non-zero angle relative to the emission plane.

[0005] In some examples, the light emitted along the emission plane can define an emission angle that is between about 25-degrees and about 75-degrees relative to the emission plane.

[0006] In some examples, the reflector can direct the portion of the emission of light normal to the emission plane.

[0007] In some examples, the reflector can extend from a first end positioned at the first cover to a second end that is positioned between the first cover and the second cover to overlap 1QB\ 100660394.1the peripheral lens. The reflector can include a reflective surface that is at a non-zero angle relative to the emission plane.

[0008] In some examples, the second end of the reflector can be positioned between the first cover and the emission plane.

[0009] In some examples, the emission plane can be between the first cover and the second end of the reflector.

[0010] In some examples, the reflector can be removably coupled to the first cover.

[0011] In some examples, the reflector can be a peripheral reflector that extends from a first side of the peripheral lens to a second side of the peripheral lens to surround at least half of the peripheral lens.

[0012] In some examples, the lighting assembly can emit light toward the peripheral lens along the emission plane.

[0013] In some examples, the lighting assembly can emit light toward the peripheral lens along a first direction that is at a non-zero angle relative to the emission plane.

[0014] According to another aspect of the present disclosure, a light system can include a housing. The housing can include a first cover, a second cover in an opposed configuration with the first cover, and a lens positioned between the first cover and the second cover, the lens including a first reflective surface. A lighting element can be positioned between the first cover and the lens. A reflector can be coupled to the first cover to be positioned external to the housing and can include a second reflective surface. The lighting element can produce an emission of light that travels along a first direction toward the first reflective surface. The emission of light can reflect off the first reflective surface to pass out of the lens in a second direction toward the second reflective surface. The first direction can be different from the second direction.

[0015] In some examples, the light passing through the lens in the second direction can reflect off the second reflective surface to travel along a third direction that is different from the second direction.

[0016] In some examples, a first portion of the light passing out of the lens can reflect off the second reflective surface and a second portion of the light passing out of the lens can pass beyond the second reflective surface.

[0017] In some examples, the second direction can be perpendicular to both the third direction and the first direction.

[0018] In some examples, the third direction can be parallel to the first direction.

[0019] In some examples, the third direction can be opposite the first direction.2QB\ 100660394.1

[0020] In some examples, the lighting element can be one of a plurality of lighting elements. The lens can be configured to direct the emission of light from the plurality of lighting elements along an emission plane that is parallel with the second direction.

[0021] In some examples, the second reflective surface can be non-planar.

[0022] In some examples, one of the first cover, the second cover, and the reflector can be configured to couple to a wearable item configured to be worn by a user.

[0023] According to yet another aspect of the present disclosure, a wearable personal protective equipment can include a wearable item configured to be worn by a user and a lighting device configured to couple to the wearable item. The lighting device can include a first cover, a second cover, a lens positioned between the first cover and the second cover to direct an emission of light along an emission plane, a lighting assembly to emit light through the lens, and a reflector coupled to the second cover and configured to direct a portion of the emission of light emitted from the lens at a non-zero angle relative to the emission plane.

[0024] According to another aspect of the present disclosure, a method of directing light from a lighting device can include providing a lighting device including a housing having a first cover, a second cover, and a lens positioned between the first cover and the second cover. A reflector can be coupled to the first cover, the reflector including a reflective surface positioned external to the housing. A lighting assembly within the housing can be activated to emit light that passes through the lens along an emission plane to be visible 360-degrees about the lighting device. A portion of the light emitted from the lens can be redirected using the reflective surface of the reflector to travel at a non-zero angle relative to the emission plane.

[0025] According to yet another aspect of the present disclosure, a method of attaching a reflector to a lighting device can include providing a lighting device including a housing having a first cover, a second cover, and a lens positioned between the first cover and the second cover. A reflector can be provided having a base that defines a channel with a first lip and a second lip. The reflector can be positioned relative to the first cover such that a periphery of the first cover is received within the channel. The reflector can be secured to the first cover by engaging the first lip with a first side of the first cover and engaging the second lip with a second side of the first cover opposite the first side to position a reflective surface of the reflector external to the housing.

[0077] 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 and terminology 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.

[0078] 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.

[0079] 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.

[0080] According to aspects of the disclosure, a lighting system can be configured as a portable or personal lighting system. For example, a lighting system 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 6QB\ 100660394.1with or mounted on personal transportation, such as on bicycles, kayaks, snowmobiles, offroad vehicles, boats, and / or other transportation systems. Personal lighting may also be integrated with specialized equipment, for example, such as skiing or snowboarding equipment, camping, hiking, or fishing equipment. Thus, in many configurations, a lighting device is configured as a portable light that can be moved to or mounted on a desired location by a user, and can be used independently of a particular support surface or structure.

[0081] As also used herein, unless otherwise defined or limited, ordinal numbers are used herein for convenience of reference based generally on the order in which particular components are presented for the relevant part of the disclosure. In this regard, for example, designations such as "first," "second," etc., generally indicate only the order in which the relevant component is introduced for discussion and generally do not indicate or require a particular spatial arrangement, functional or structural primacy or order.

[0082] In some implementations, devices or systems disclosed herein can be utilized or installed using methods embodying aspects of the disclosure. Correspondingly, description herein of particular features, capabilities, or intended purposes of a device or system is generally intended to inherently include disclosure of a method of using such features for the intended purposes, a method of implementing such capabilities, and a method of installing disclosed (or otherwise known) components to support these purposes or capabilities. Similarly, unless otherwise indicated or limited, discussion herein of any method of manufacturing or using a particular device or system, including installing the device or system, is intended to inherently include disclosure, as embodiments of the disclosure, of the utilized features and implemented capabilities of such device or system.

[0083] FIG. 1 depicts an example of a lighting system 100 that optionally includes a wearable personal protective equipment upon which lighting devices can be mounted to improve worker visibility and safety. Wearable personal protective equipment can include various types of wearable items, such as clothing items (e.g., gloves, hats, pants, shirts, jackets, vests, or other types of garments) and accessories (e.g., safety glasses, hardhats, etc.). In this case, the lighting system 100 includes a lighting device configured as a safety light 102 (e.g., an emergency beacon, construction lighting, mining light, police or fire lighting, ambulance lighting, or any of a variety of personal or deployable lighting). The safety light 102 is coupled to an item of wearable personal protective equipment 104 (e.g., a wearable item 104). The wearable personal protective equipment 104 is depicted as a safety vest but can also be used with other types of wearable personal protective equipment. As described in greater detail below, the safety light 102 can be coupled directly to the wearable personal protective 7QB\ 100660394.1equipment 104 or the safety light 102 can be coupled to the wearable personal protective equipment 104 via a mounting interface (e.g., an adaptor, a reflector, or another accessory).

[0084] Light can be emitted from a lighting device (e.g., the safety light 102) 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 102. 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, light emitted from a lighting device can be viewed from at least 360-degrees around the lighting device. For example, the 360-degree emission of light can be emitted along an emission plane. The emission of light may spread from the emission plane to define an emission angle relative to the emission plane. The emission angle can be 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 45-degrees, or any other range therein, as required by a particular application.

[0085] Additionally, 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 corresponding to a beam axis. In such examples, the beam of light can spread from the beam axis to define a beam angle relative to the beam axis. The beam angle can be 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 45-degrees, or any other range therein, as required by a particular application.

[0086] Light emitted from a lighting device (e.g., the safety light 102) 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 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 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 8QB\ 100660394.1to 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.

[0087] 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. Relatedly, to allow light to be emitted, the lighting device 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 a 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 a lighting device. Accordingly, a lighting device can include multiple lenses positioned about the periphery of the housing so that light can be viewed from at least 360-degrees around the lighting device.

[0088] For example, with continued reference to FIGS. 2-13, the safety light 102 generally includes a lens structure 110 (e.g., a lens 110) positioned between a first cover 112 (e.g., a bottom cover) and a second cover 114 (e.g., a top cover). The lens 110 can be secured between the first cover 112 and the second cover 114 in a variety of ways. For example, fasteners can be inserted through the first cover 112 to engage with the second cover 114, or snap-fit connections can be provided between the lens 110 and each of the first cover 112 and the second cover 114. Other methods of joining components of a housing can also be used.

[0089] The lens 110, the first cover 112, and the second cover 114 can collectively form a housing 120 defining an interior space 122 (shown in FIG. 12) that is configured to retain a lighting assembly therein. In some cases, gaskets can be provided between housing components to prevent ingress of water or other contaminants (dust, debris, etc.). For example, as shown in FIG. 12, a first gasket 116 is positioned between the first cover 112 and the lens 110, and a second gasket 118 is positioned between the second cover 114 and the lens 110. In other examples, a cover or a lens can be self-sealing and may not require a separate gasket element.9QB\ 100660394.1

[0090] The housing 120 can provide protection to the comparatively sensitive and fragile components of the lighting assembly, allowing the safety light 102 to be used in a 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 and / or particulate matter (e.g., dust, debris, etc.). 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.

[0091] 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 120 is configured as a generally cuboid body, and more specifically, a rectangular cuboid. Put another way, the housing 120 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 120. 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.

[0092] In the illustrated embodiment, the first cover 112 can define a first side 124 (e.g., a bottom side) of the housing 120 and the second cover 114 can define a second side 126 (e.g., a top side) of the housing 120. Correspondingly, as shown in FIGS. 6-9, the lens 110 is positioned between the first side 124 and the second side 126 and can define a third side 128 (e.g., a front side), a fourth side 130 (e.g., a rear side), a fifth side 132 (e.g., a left side), and a sixth side 136 (e.g., a right side) of the housing 120. The first cover 112 and the second cover 114 form a sandwich arrangement with respect to the lens 110, in which the third side 128, the fourth side 130, the fifth side 132, and the sixth side 136 extend substantially perpendicularly between the first cover 112 and the second cover 114. Accordingly, the lens 110 can form a periphery of the housing 120 between the first cover 112 and the second cover 114, and can further define an interior thickness and / or depth of the safety light 102. That is, the lens 110 and each of the first cover 112 and the second cover 114 form a hollow housing having the interior space 122 that is configured to receive one or more components of the safety light 102. For example, the housing 120 may contain a circuit board 140 configured to support and / or10QB\ 100660394.1electrically connect various electrical components, a power source (e.g., a battery 142), and one or more lighting assemblies configured to emit light (see FIGS. 11-13).

[0093] To provide the safety light 102 with sufficient strength and structural integrity, while also being light weight and portable, the first cover 112 and the second cover 114 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 120 or a portion of the housing 120 (e.g., the first cover 112 and / or the second cover 114) may be made from a metallic material (e.g., aluminum, titanium, etc.) to facilitate the dissipation of heat from within the safety light 102 (e.g., from one or more LEDs, a processor, and / or a power source, etc.).

[0094] Correspondingly, the shape of the lens 110 can provide the safety light 102 with an optically transparent perimeter that allows light to be observed from at least 360-degrees around the safety light 102. That is, the shape of the lens 110 can allow light to be emitted around an entire perimeter of the safety light 102. Accordingly, the lens 110 can be made of a transparent or translucent material, for example, a polymer (e.g., polycarbonate, PMMA, acrylic, transparent ABS (MABS), and urethanes (Trivex®)) or a non-polymeric material (e.g., glass, such as borosilicate glasses, and optical silicones). Like with the first cover 112 and the second cover 114, the material of the lens 110 can be selected to provide the safety light 102 with sufficient strength and structural integrity, while also being light weight and portable. Further details regarding the lens 110 and the transmission (i.e., emission) of light through the lens 110 are described below. In some 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 and are also contemplated and are within the scope of the present disclosure.

[0095] In some cases, a lens can define multiple individual lens elements or waveguides 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 11QB\ 100660394.1example, 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.

[0096] As described in greater detail below, a lighting device (e.g., the safety light 102), 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 or more functions of the lighting device. In particular, a user can control the emission of light from the lighting device. The user interface can allow a user to control the emission of light from a lighting assembly of the lighting device. Such control interfaces 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. 2-11, the housing 120 includes a user interface having a plurality of buttons 146 that are configured to control one or more functions of the safety light 102 (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.).

[0097] For example, to operate the safety light 102 manually, the second cover 114 includes the buttons 146 (e.g., the buttons 146 are provided at the second cover 114), which are configured to activate and / or adjust one or more features of the safety light 102, such as light intensity (brightness), light pattern (e.g., strobe, flash, blink, constant, etc.), or power to the light emitting elements. In some cases, the buttons 146 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 the battery 142), etc. In some examples, buttons can be integrated into a gasket. For example, as shown in FIG. 10, the buttons 146 are integrated into the second gasket 118 to provide sealing at openings in the second cover 114 that accommodate the buttons 146.

[0098] 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 12QB\ 100660394.1device can also be controlled based on an external signal that is received by the safety light 102 (e.g., a Bluetooth, radio, or other type of wireless communication). In this way, the lighting device can be controlled without requiring a physical input from a user.

[0099] To provide the electrical power for operation of the safety light 102, the circuit board 140 can be coupled to a power source that is configured to store energy for later use by the safety light 102. Here the power source is configured as the battery 142 (see e.g., FIG. 12), 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, are also contemplated. 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, processor, 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.

[0100] In one example, a power source can be indirectly supported by the circuit board 140 via wires that electrically connect the power source to the circuit board 140, or a power source can be directly supported by the circuit board 140. In some embodiments, the wires can removably couple (e.g., via a connector) to the circuit board 140 to allow for the battery 142 to be replaced. The battery 142 can be positioned below the circuit board 140 (e.g., between the circuit board 140 and the first cover 112) and can be in electrical connection with the circuit board 140 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 142 may be charged via wireless charging and / or via a port 152 (e.g., a data transfer / charge port, see FIG. 2). The port 152 can be sealed with a cover 154. The cover 154 can be coupled to the first cover 112 via a hinge. In other cases, the port 152 or the cover 154 can be arranged differently (e.g., to be on the second cover 114, on a bottom of the first cover 112, etc.).

[0101] 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 13QB\ 100660394.1magnetically 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 headbands, adjustable straps, lanyards, tilting mounts, inserts for traffic cones, auxiliary battery packs, and clips.

[0102] In some cases, connection structures can be configured to provide one or more magnetic connections. Magnets that can provide strong magnetic coupling are preferable 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.

[0103] 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, as shown in FIG. 12, the first cover 112 can be configured to couple to a magnet 156. As illustrated, the first cover 112 includes a magnet tray 158 that is configured to selectively house and retain the magnet 156 (see FIG. 12). The magnet 156 may be used to quickly and selectively mount the safety light 102 in various locations, such as on a vehicle, on clothing, on predetermined accessories, and / or other magnetic locations. In particular, the magnet 156 can allow the safety light 102 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 102 (e.g., a magnetic accessory that can magnetically couple to the safety light 102).

[0104] When the safety light 102 is coupled with (i.e., magnetically coupled with) an accessory, an article (i.e., an object) can be disposed between the accessory and the safety light 102 (e.g., the magnet 156) to attach the safety light 102 to said article. For example, a clothing item (e.g., a wearable item such as a jacket, a shirt, pants, a belt, or headwear) may be disposed between a mounting plate and the magnet 156, wherein the magnet 156 is coupled to the mounting plate through the clothing item, thereby releasably attaching the safety light 102 to the clothing. Some non-limiting examples of articles to which a light can be attached include 14QB\ 100660394.1clothing, 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.

[0105] In that regard, a wearable item (e.g., the wearable item 104) can include a mounting bracket that is integrated into the wearable item (e.g., formed with or otherwise non-removably attached to the wearable item). In other examples, a mounting bracket can be separate from a wearable item. Accordingly, the mounting bracket can be attached to the wearable item 104. For example, the wearable item 104 can be secured between a lighting device (e.g., the safety light 102) and the mounting bracket. In some cases, a mounting bracket can be formed as an external reflector in accordance with aspects of the present disclosure.

[0106] Further, in some embodiments, a housing of a lighting device can 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 orienting features configured to allow the lighting device to couple with another object in a specific way. For example, one or more alignment protrusions 160 may surround the magnet tray 158. The alignment protrusions 160 may serve as orienting and / or aligning features to ensure proper alignment of the magnet tray 158 on a charger and / or wireless data transfer device. In other examples, the alignment protrusions 160 may be used in combination with one or more predetermined accessories and / or mounting devices to secure the safety light 102 in place.

[0107] 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 112 may be molded and / or formed to further define a mounting point 162 (see FIG. 11), which is configured to receive a lanyard and / or other connection device. The mounting point 162 may receive a lanyard to attach the safety light 102 to a user, a vehicle, and / or other device to prevent loss of the safety light 102. To further assist in permanent and / or temporary mounting of the safety light 102, the safety light 102 can include one or more inserts 164 provided on the alignment protrusions 160. In some cases, the inserts 164 can be threaded inserts configured to receive a fastener, such as a threaded fastener to secure the safety light 102 into a desired position. Alternatively, the inserts 164 can be configured as terminals to provide other types of connections, for example, to provide electrical connections for internal components within the safety light 102, such as for charging, communication, etc.

[0108] 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 15QB\ 100660394.1lens can be tailored to provide a desired output of light, for example, by controlling the refraction or reflection of light passing through the lens. In that regard, a lens can be configured to 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., collimated, 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 configured to 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 this regard, a lens can be configured as a prism, which can direct light in a transverse direction. 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.

[0109] As previously mentioned, a safety light can be configured to receive an emission of light from a lighting assembly to selectively provide a 360-degree emission of light. In the illustrated example, the safety light 102 includes a lighting assembly 170 that produces an emission of light 168. This emission of light 168 passes into the lens 110 and is directed out of the lens 110 along an emission plane 172, which is a center plane that the emission of light 168 travels along upon exiting the lens 110. As the emission of light 168 moves in a direction along the emission plane 172, the emission of light 168 may spread to define an emission angle 174 relative to the emission plane 172. In the illustrated example, the emission plane 172 extends between the first cover 112 and the second cover 114 to bisect the lens 110. More specifically, the emission plane 172 is substantially parallel to the first cover 112 and the second cover 114. In other examples, the emission plane 172 may be different, for example, to be closer to one of the first cover 112 or the second cover 114. Moreover, the emission plane 172 may be at a nonzero angle relative to the first cover 112 and the second cover 114.

[0110] A lighting assembly can include a plurality of lighting elements that can be selectively activated (e.g., via an electronic controller in accordance with a user input) to produce an emission of light from the periphery of a safety light (e.g., side surfaces of a lens). In some cases, lighting elements 176 of the lighting assembly 170 can be selectively activated so that only a portion of the 360-degree emission is active at a particular instance in time, for example, to produce a 90-degree emission, a 180-degree emission, or another range of emission of light about the periphery of the safety light 102. Correspondingly, the lighting elements 17616QB\ 100660394.1of the lighting assembly 170 can be activated individually, as different subsets, or all at once to produce a desired emission (e.g., a desired emission pattern).

[0111] Lighting assemblies can be arranged in various ways within a safety light to achieve a desired output. In the illustrated example, the lighting elements 176 forming the lighting assembly 170 are coupled to the circuit board 140 so that the lighting elements 176 are positioned between the lens 110 and the second cover 114. The lighting elements 176 are positioned between the circuit board 140 and the lens 110 and are aimed to produce the emission of light 168 along a first direction 178 toward the lens 110 and the first cover 112. In this way, the emission of light 168 enters the lens 110 through a top surface of the lens 110. By positioning the lighting elements 176 proximate the second cover 114, heat from the lighting elements 176 can be more efficiently dissipated from the safety light 102. In other examples, lighting elements can be positioned differently, for example, to emit light directly through an interior side surface of a lens, a bottom surface of the lens, or another surface of the lens. The particular position of a lighting element can be selected to achieve desired light emission properties (e.g., brightness, color options, directions of emission, heat dissipation, etc.).

[0112] Relatedly, and as mentioned above, a lens can be configured to collect and control the light emitted by a lighting element. As illustrated, the lens 110 includes a waveguide 180 that redirects the emission of light 168 entering the lens 110 so that the emission of light 168 passes out of the side surfaces of the lens 110 in a second direction 182 to travel along the emission plane 172. In the illustrated example, the waveguide 180 includes a reflective surface 184 that is shaped to direct the emission of light 168 entering the lens 110 along the second direction 182. The reflective surface 184 is illustrated as a sloped surface that is angled relative to the first direction 178 and the second direction 182 (e.g., at about a 45-degree angle). The reflective surface 184 can reflect light via a reflective coating, or via total internal reflection. In other examples, the waveguide 180 may be shaped differently to produce a desired output from the lens 110. For example, the reflective surface 184 can be curved or scalloped to control light diffusion, emission angle, etc.

[0113] In some applications, it can be beneficial to redirect a portion (e.g., some or all) of the 360-degree emission (e.g., the emission of light 168) to extend along a different direction that is at a non-zero angle relative to the emission plane 172. For example, in a cone mount configuration, a portion of the 360-degree emission can be used to illuminate a region around the base of the cone while still allowing some of the emission to be directed outward toward an observer. In other cases, light can be reflected to reduce glare in a given direction (e.g., to block glare from reaching the eyes of a user).17QB\ 100660394.1

[0114] For example, with additional reference to FIGS. 14-16, the lighting system 100 (e.g., the safety light 102) includes a reflector 200 configured to couple to the safety light 102. As will be described in greater detail below, the reflector 200 includes a base 204 configured to couple to the safety light 102 and a reflective surface 208 to reflect the emission of light 168 along a desired direction. The reflective surface 208 can include a reflective coating, a reflective panel (e.g., that is separate and coupled to the reflector 200, or formed as part of the reflector 200), or a polished surface that increases reflectivity relative to the safety light 102. The reflective surface 208 is provided on a flange 210 that extends from the base 204. The reflective surface 208 is positioned external to the housing 120 to redirect a portion of the emission of light 168 in a third direction 186 that is at a non-zero angle relative to the second direction 182 (e.g., the emission direction), and correspondingly, the emission plane 172. In the instant example, the third direction 186 is parallel and opposite the first direction 178 and orthogonal to the second direction 182. In other examples, the third direction 186 can be different, for example, to be parallel and in the same direction as the first direction 178 and orthogonal to the second direction 182, or at an oblique angle relative to one or both of the first direction 178 or the second direction 182. Correspondingly, the reflective surface 208 is at a selected angle 212 relative to the emission plane 172 (or another relevant surface, such as a side surface of the lens 110) to cause the emission of light 168 to travel along the third direction 186. While the reflective surface 208 shown in FIGS. 14-16 is generally smooth, it is also contemplated that the reflective surface 208 can be dimpled, ribbed, curved, scalloped, or have other features to manipulate the emission of light 168 to be, for example, diffuse or columnated, or to adjust an emission angle relative to the second direction 182.

[0115] In some examples, the reflective surface 208 can extend across the lens 110 (e.g., in a direction between the first cover 112 and the second cover 114). Here, the reflective surface 208 (and the flange 210) extends from a proximal end 216 at the base 204 to a distal end 218 away from the base 204. The reflective surface 208 crosses the emission plane 172 so that the proximal end 216 is on a first side of the emission plane 172 (e.g., proximate the first cover 112) and the distal end 218 is on a second side of the emission plane 172 that is opposite the first side (e.g., proximate the second cover 114). In other cases, the reflective surface 208 may not cross the emission plane 172 to redirect a smaller proportion of the emission of light 168.

[0116] The extent to which the reflective surface 208 extends across the lens 110 can be selected to control the proportion of light that is redirected by the reflector 200. For example, the lens 110 can define a height 220 between the first cover 112 and the second cover 114 and the reflector 200 may define a corresponding length 224. A ratio between the height 220 and 18QB\ 100660394.1the length 224 can range between about 1:10 and about 1 : 1. In the illustrated embodiment, the ratio is about 3:4. While it may be preferable that the reflective surface 208 extends across a portion of the lens 110, this may not always be the case. For example, the reflective surface 208 may be positioned out of alignment (e.g., entirely above or below) the lens 110. In this way, the reflective surface 208 redirects light that has diffused or spread in accordance with the emission angle 174. Such arrangements may be particularly useful by limiting impact on primary beam strength (e.g., the 360-degree emission of light 168) and repurposing or redirecting diffused light that may otherwise contribute to glare.

[0117] In some cases, a reflector can include a reflective surface that extends around some or all of a periphery of a lighting device. In the illustrated example, the reflector 200 (e.g., the flange 210 and the reflective surface 208) surrounds an entire periphery of the lens 110 so that the reflective surface 208 extends along each side of the lens 110. In other examples, the reflective surface 208 may only extend around a portion of the periphery of the lens 110 (e.g., to extend along any subset of the sides of the lens 110). For example, as discussed in greater detail below, a reflector can include cutouts to accommodate various components of a lighting device.

[0118] A reflector can be configured to couple to a lighting device in a variety of ways to control the light emission from the lighting device. As briefly mentioned above, a reflector can include a base that supports a reflective surface to position the reflective surface relative to the lighting device. For example, a base of a reflector can include a magnet or be made of a magnetic material to allow the reflector to magnetically couple to the lighting device. In some examples, a base can interface with another connection interface of a lighting device, such as snap fit connections, threaded inserts, etc. Correspondingly, a reflector can be configured to couple with a cover of the lighting device or directly to a lens of a lighting device.

[0119] In the illustrated example in FIGS. 14-16, the reflector 200 is configured to couple with either the first cover 112 or the second cover 114 to position the reflective surface 208 across the lens 110 (e.g., to align the reflective surface 208 with the lens 110). Correspondingly, while the description below is discussed in relation to the first cover 112, similar principles apply to the second cover 114 (see, e.g., the illustrated example in FIGS. 21-28). The reflector 200 is configured as a clamp-style reflector with a first half 232 and a second half 234 that removably couple to one another. Here, the first half 232 and the second half 234 are coupled via fasteners 236 that are received in respective bores 237 of respective bosses 238. In other examples, the first half 232 and the second half 234 can be coupled in other ways, for example, by snap fit connection, magnets, adhesives, etc. To ensure a secure connection with the first 19QB\ 100660394.1cover 112, the base 204 can define a channel 240 that is configured to receive the first cover 112. More specifically, the first cover 112 defines a periphery (e.g., a protruding edge or side) that extends past the side surfaces of the lens 110. The protruding portion of the first cover 112 is received in the channel 240 to be enclosed by the base 204 of the reflector 200.

[0120] To prevent the reflector 200 from moving relative to the lens 110 in a direction toward or away from the lens 110 (e.g., toward or away from the second cover 114), the channel 240 defines a first lip 244 (e.g., a first rim) and a second lip 246 (e.g., a second rim). When the reflector 200 is coupled to the first cover 112, the first lip 244 is positioned to extend over a first side 245 of the first cover 112 that faces the lens 110. In this way, the first lip 244 prevents movement of the reflector 200 away from the lens 110 and the second cover 114. Similarly, the second lip 246 is positioned to extend over a second side 247 of the first cover 112 that is opposite the first side 245 and the lens 110. In this way, the second lip 246 prevents movement of the reflector 200 toward the lens 110 and the second cover 114.

[0121] In some cases, a base of a reflector can be shaped as an annulus (e.g., a square, circular, triangular, etc.) to allow for access to other features of a lighting device, such as a user interface, connection interface, data or charging ports, etc. As shown in FIGS. 3 and 14-16, the base 204 of the reflector 200 has an annular shape with a peripheral wall 248 that defines the channel 240. The annular shape of the peripheral wall 248 provides an opening 252 through which the first cover 112 can be accessed when the reflector 200 is attached to the safety light 102. For example, FIG. 3 illustrates how the magnet tray 158 is exposed through the opening 252 to be accessible to a user. Similarly, the alignment protrusions 160 and the inserts 164 are also exposed through the opening 252. Accordingly, the safety light 102 can be coupled to a mount (e.g., the wearable item 104) while the reflector 200 is attached to the safety light 102. Similarly, when the reflector 200 is attached to the second cover 114, the buttons 146 are exposed through the opening 252 so that the buttons 146 can be accessed by a user to control the emission of light 168 (e.g., to turn lighting elements on or off, or change a color, pattern, or intensity of an emission of light, etc.) or control another function of the safety light 102 (e.g., a Bluetooth connection, GPS signal, etc.).

[0122] A reflector can also include other structural features to allow for normal light operation when the reflector is coupled with a safety light. For example, the reflector 200 includes an aperture 256 in the peripheral wall 248 to accommodate the mounting point 162. The aperture 256 in the peripheral wall 248 allows a user to access the mounting point 162, for example, by allowing the mounting point 162 to extend through the peripheral wall 248. As another example, the base 204 and the flange 210 of the reflector 200 include a cutout 260 to 20QB\ 100660394.1provide access to the port 152. The cutout 260 is sized to allow the cover 154 for the port 152 to be opened to allow a cable to be inserted into the port 152 for charging. Correspondingly, the reflector 200 defines recesses 264 on opposing sides of the cutout 260. The recesses 264 are configured to accommodate a hinge of the cover 154 to allow the cover 154 to be pivoted between an open position and a closed position.

[0123] In some examples, a reflector for the lighting system 100 can include a hinge to allow the reflector to be secured to the safety light 102. For example, FIGS. 17-19 illustrate a reflector 300 that is configured to couple to the safety light 102. Unless indicated otherwise, the components, functionality, and advantages of the reflector 200 illustrated in FIGS. 14-16 apply similarly to the illustrated example of the reflector 300 in FIGS. 17-19. Correspondingly, similar components and features of the “200” series of reference numerals are denoted in the "300" series of reference numerals, unless otherwise provided.

[0124] A reflector can be configured to allow a user to open and close the reflector. For example, a first half and a second half of a reflector can be coupled to allow the first half and the second half to move relative to one another between an open configuration and a closed configuration. As illustrated in FIGS. 17-19, the reflector 300 includes a first half 332 and a second half 334 that removably couple to one another. For example, the first half 332 and the second half 334 are coupled via a first fastener 336, here configured as a thumb screw for toolless attachment, that is received in a first set of bores 337 of a first set of bosses 338. The first fastener 336 is depicted as a thumb screw for toolless attachment; however, other types of fasteners can be used, including for toolless or tooled attachment (e.g., a pin, wing nut, clevis, etc.). The first fastener 336 can engage with a retainer 339 (e.g., in or on the first set of bores 337) to prevent the first fastener 336 from disengaging with the reflector 300 when unscrewed. In some examples, the retainer 339 can include an interference fit or resilient feature that maintains the first fastener 336 in position while allowing rotational movement for toolless attachment and removal of the first fastener 336.

[0125] In some cases, the first half 332 and the second half 334 are further attached by a second fastener 370 that is received in a second set of bosses, here configured as knuckles of a hinge 372. The hinge 372 includes a first set of knuckles 374 coupled to the first half 332 and a second set of knuckles 376 coupled to the second half 334. The first set of knuckles 374 and the second set of knuckles 376 interlock and define an opening 378 configured to receive the second fastener 370 (e.g., a hinge pin). The hinge 372 is positioned on a peripheral wall 348 opposite the first set of bosses 338 across an opening 352. The hinge 372 is configured to allow the first half 332 and the second half 334 to rotate about an axis 382 defined by the first set of 21QB\ 100660394.1knuckles 374 and the second set of knuckles 376. Accordingly, the reflector 300 can move between the open configuration and the closed configuration.

[0126] The hinge 372 allows the first half 332 and the second half 334 to remain connected when in both the open configuration and the closed configuration. For example, the second fastener 370 couples the first half 332 with the second half 334 when the second fastener 370 is inserted along the axis 382 and into the opening 378 of the hinge 372. Correspondingly, the first fastener 336 secures the first half 332 and the second half 334 in the closed configuration when the first fastener 336 is translated along an axis 384 and is received in the respective bores 337 of each of the first set of bosses 338. In the illustrated example, the first fastener 336 includes threads to couple with corresponding threads in at least one of the bores 337 of the first set of bosses 338. In some examples, the axis 384 and the axis 382 are perpendicular to one another.

[0127] The second fastener 370 is configured as a pin with an engagement feature 380 that secures the second fastener 370 to one of the first half 332 and the second half 334. In the illustrated example, the engagement feature 380 is configured as a textured surface (e.g., a knurled region) that contacts the first set of knuckles 374 and the second set of knuckles 376 and increases friction between the second fastener 370 and the first set of knuckles 374 and the second set of knuckles 376. Accordingly, the textured surface (i.e., the engagement feature 380) limits the second fastener 370 from translating relative to the hinge 372 along the axis 382 or rotating about the axis 382. While FIGS. 17-19 illustrate the engagement feature 380 having a surface texture as a press-in knurled detail, the second fastener 370 can have other surface textures such as helical knurls, diamond knurls, barbs, serrations, etc., and combinations thereof.

[0128] In some examples, a lighting system can have a mounting point located on a reflector. By integrating the mounting point into the reflector, the reflector does not require (although it may still include) an aperture to accommodate a mounting point that protrudes from the first cover. This configuration may, in some cases, allow for mounting points that are easier to access, or allow for multiple mounting points to be provided on the lighting system.

[0129] Continuing to refer to FIGS. 17-19, the reflector can also include an attachment point for different types of couplings. For example, the reflector 300 includes a recess 356 that accommodates the mounting point 162. As such, the reflector 300 blocks access of a user to the mounting point 162. Instead, the reflector 300 includes a second mounting point 362 molded and / or formed with the peripheral wall 348. The second mounting point 362 is configured to receive a lanyard and / or other connection device. The second mounting point 22QB\ 100660394.1362 may receive a lanyard to attach the safety light 102 to a user, a vehicle, and / or other device to prevent loss of the safety light 102.

[0130] In some examples, a lighting system can have a mounting point being located on a reflector. By integrating the mounting point into the reflector, the reflector does not require (although it may still include) an aperture to accommodate the mounting point that protrudes from the first cover. This may, in some cases, allow for mounting points that are easier to access, or allow for multiple mounting points.

[0131] In some examples, a reflector for the lighting system 100 can include a rim that protects a reflective surface of the reflector. For example, FIGS. 20-32 illustrate a reflector 400 that is configured to couple to the safety light 102. Unless indicated otherwise, the components, functionality, and advantages of the reflector 300 illustrated in FIGS. 17-19 apply similarly to the illustrated example of the reflector 400 in FIGS. 20-32. Correspondingly, similar components and features of the “300” series of reference numerals are denoted in the "400" series of reference numerals, unless otherwise provided.

[0132] In some cases, a reflector can include a protector to help reduce the risk of damage to a reflective surface. For example, the reflector 400 includes a rim 486 that protects a reflective surface 408 provided on a flange 410 of the reflector 400. The rim 486 extends outward from a distal end 418 of the reflective surface 408 (e.g., away from an opening 452 of the reflector 400). In this way, the rim 486 is configured to protect the reflective surface 408 without disrupting the emission of light 168 that is reflected off of the reflective surface 408 during operation of the safety light 102. The rim 486 can shield the reflective surface 408 from impacts, abrasion, scratches, debris, dust, moisture, and other environmental factors that could otherwise degrade the reflective properties of the reflective surface 408 over time. In some examples, the rim 486 extends around some or all of a periphery of the reflector 400. For instance, the rim 486 can extend continuously around an entire periphery of the reflector 400, or the rim 486 can extend around only a portion of the periphery, such as around at least 25%, at least 50%, at least 75%, or at least 90% of the periphery.

[0133] In some examples, the rim 486 is made of the same material as a base 404 of the reflector 400. In other examples, the rim 486 can be made of a different material than the base 404, such as a more resilient or impact-resistant material including rubber, silicone, thermoplastic elastomer (TPE), polyurethane, or other elastomeric materials.

[0134] In some examples, the rim 486 can be integrally formed with the flange 410 or the base 404 as a unitary structure. Alternatively, the rim 486 can be a separate component that is attached to the flange 410 or the base 404 via adhesive, mechanical fasteners, snap-fit 23QB\ 100660394.1connections, press-fit connections, overmolding, or other attachment methods. The rim 486 can have a variety of cross-sectional shapes, including rectangular, rounded, triangular, L-shaped, or T-shaped profiles. In some examples, the rim 486 can include a cushioning or shockabsorbing layer to further protect the reflective surface 408 from impacts. The rim 486 can extend outward from the distal end 418 at various angles relative to the reflective surface 408, including perpendicular to the reflective surface 408, parallel to the emission plane 172, or at an oblique angle therebetween.

[0135] In some examples, a rim can include access features, as may allow for assembly or operation of the reflector. For example, the rim 486 extends over an opening 478 defined by a first set of knuckles 474 and a second set of knuckles 476 of the reflector 400. As such, the rim 486 may block a pin 470 from being received in the opening 478. To accommodate the pin 470 when the pin 470 is received by the opening 478, the rim 486 can include a cut out 488. The cut out 488 is located on the rim 486 so that the pin 470 can be received by the opening 478 without contacting the rim 486.

[0136] Referring to FIG. 32, in some examples, a bore of a reflector (e.g., a bore for receiving a removable fastener) can include multiple diameters to receive and retain a fastener that couples a first half and a second half of the reflector. For example, the bores 437 of the reflector 400 include a first chamber 490 having a first diameter 490a, a second chamber 491 having a second diameter 491a, and a third chamber 492 having a third diameter 492a. The first chamber 490 and the third chamber 492 are positioned on opposite ends of the bores 437. As a result, the first chamber 490 is located on one half of the reflector 400 and the third chamber 492 is located on the other half of the reflector 400. In the illustrated example, the first chamber 490 is on a first half 432 and the second chamber 492 is on a second half 434. The second chamber 491 is positioned between the first chamber 490 and the third chamber 492 and connects the first chamber 490 with the third chamber 492. In some examples, the second chamber 491 spans across both the first half 432 and the second half 434 of the reflector 400. In some examples, the second diameter 491a of the second chamber 491 is greater than the first diameter 490a of the first chamber 490 and the third diameter 492a of the third chamber 492. In some examples, the first diameter 490a of the first chamber 490 and the third diameter 492a of the third chamber 492 are substantially the same. At least one of the first chamber 490 and the third chamber 492 includes threads configured to threadingly engage a fastener 436, as will be described in greater detail below. In the illustrated example, the third chamber 492 includes the threads.24QB\ 100660394.1

[0137] The bores 437 are configured to receive the fastener 436 to couple the first half 432 and the second half 434 of the reflector 400 together. The fastener 436 includes a head 494 and a body 496 that are separated by a neck 498. The head 494 has a head diameter 494a and the body 496 has a body diameter 496a that is less than the head diameter 494a. As such, the neck 498 defines a surface that separates the head 494 from the body 496 and provides a transition between the head diameter 494a and the body diameter 496a. The body diameter 496a corresponds with the first diameter 490a of the first chamber 490 and the third diameter 492a of the third chamber 492 so that the body 496 can be received through the bores 437. Conversely, the head diameter 494a is greater than the first diameter 490a of the first chamber 490 and the third diameter 492a of the third chamber 492 so that the head 494 is blocked from being received through the bores 437. In this way, the neck 498 contacts a surface of the boss 438 to limit advancement of the fastener 436 through the bores 437. The body 496 can include threads configured to threadingly engage the threads of the third chamber 492. In some examples, the body 496 has threads on an end opposite the head 494.

[0138] A reflector can include a retainer configured to prevent dislodgement of a fastener from a bore of the reflector. For example, the retainer 439 is configured to be received within the second chamber 491 of the bores 437. The retainer 439 has a retainer diameter 439a that is less than the second diameter 491a of the second chamber 491 and that is greater than the first diameter 490a of the first chamber 490 and the third diameter 492a of the third chamber 492. As such, the retainer 439 is configured to be received by the second chamber 491 and is blocked from entering the first chamber 490 and the third chamber 492.

[0139] In the illustrated example, the retainer 439 is configured as a ring, such as a circlip or a snap ring, that is received in a slot 499 defined by the fastener 436. The slot 499 can be positioned on the body 496 of the fastener 436 between the head 494 and the threaded end of the body 496. When the fastener 436 is inserted through the bores 437, the retainer 439 engages with the slot 499 to maintain the fastener 436 in position within the bores 437. The retainer 439 can be a split ring that is configured to expand or contract to be received within the slot 499 and to engage with surfaces of the second chamber 491. In some examples, the retainer 439 can be a C-shaped or E-shaped clip that snaps into the slot 499. The engagement between the retainer 439 and the slot 499 limits axial movement of the fastener 436 relative to the bores 437 when the fastener 436 is in an unsecured or loosened position, thereby preventing the fastener 436 from being inadvertently removed or lost from the reflector 400.

[0140] To secure the fastener 436 to the reflector 400 (and thereby couple the first half 432 and the second half 434), the body 496 of the fastener 436 is inserted through the bores 25QB\ 100660394.1437 on an end defining the first chamber 490. Since the body diameter 496a is less than the first diameter 490a of the first chamber 490 and the second diameter 491a of the second chamber 491, the body 496 is translated through the first chamber 490 and the second chamber 491. As the body 496 advances through the bores 437, the body 496 is received by the retainer 439, which is positioned within the second chamber 491. The retainer 439 engages with the body 496 to maintain the fastener 436 in position within the bores 437. The body 496 threadingly engages with the threads of the third chamber 492. As the fastener 436 is rotated, the fastener 436 advances further into the bores 437 until the neck 498 contacts the respective boss 438, thereby blocking the fastener 436 from further advancement into the bores 437 and securing the first half 432 to the second half 434 of the reflector 400.

[0141] In some examples, a bore of a reflector can include an integral retainer that is formed as a unitary piece with the reflector to secure and block further advancement of a fastener that is received in the bore. For example, FIGS. 33-37 illustrate a reflector 500 that is configured to couple to the safety light 102. Unless indicated otherwise, the components, functionality, and advantages of the reflector 400 illustrated in FIGS. 20-32 apply similarly to the illustrated example of the reflector 500 in FIGS. 33-37. Correspondingly, similar components and features of the “400” series of reference numerals are denoted in the “500” series of reference numerals, unless otherwise provided.

[0142] Referring to FIG. 36, the reflector 500 includes bores 537 defined by a set of bosses 538 that are configured to receive a fastener 536 to couple a first half 532 and a second half 534 of the reflector 500. The bores 537 define a first chamber 590, a second chamber 591, and a third chamber 592. The first chamber 590 and the third chamber 592 are positioned on opposite ends of the bores 537. As a result, the first chamber 590 is on one half of the reflector 500 and the third chamber 592 is on the other half of the reflector 500. In the illustrated example, the first chamber 590 is on the first half 532 and the third chamber 592 is on the second half 534. The second chamber 591 is positioned between the first chamber 590 and the third chamber 592 and connects the first chamber 590 and the third chamber 592. In some examples, the third chamber 592 includes threads configured to threadingly engage the fastener 536. The threads may be formed in a threaded insert 602 that is coupled to the reflector 500.

[0143] A bore of a reflector can include one or more retainers (e.g., a barb, a finger, a protrusion, etc.) that reduce a diameter of a portion of the bore. In this way, a barb can selectively allow or prevent translation of a fastener through the bore depending on a local diameter of the fastener. For example, with additional reference to FIG. 37, the bores 537 include a barb 593 that protrudes inward from a wall of the bores 537 and separates the first 26QB\ 100660394.1chamber 590 from the second chamber 591. The barb 593 has an annular shape that defines a barb opening 594. Since the barb 593 protrudes inward from the wall of the bores 537, the barb opening 594 has a barb opening diameter 594a that is less than a diameter 537a of the bores 537. In some examples, the barb 593 is configured to contact the fastener 536 to block the fastener 536 from further advancement into the bores 537, as will be described in greater detail below.

[0144] In some examples, the barb 593 is angled at a first angle 593a relative to the wall of the bores 537. The first angle 593a can be selected to correspond with an angle of a surface of the fastener 536 to provide secure engagement between the barb 593 and the fastener 536. In some examples, the barb 593 is configured to permit one-way insertion of the fastener 536 into the bores 537. The first angle 593a of the barb 593 defines a ramped surface 593b that allows the fastener 536 to be inserted into the bores 537 by deflecting the barb 593 radially outward as the fastener 536 advances through the barb opening 594. The barb 593 can be configured to resiliently flex in a radially outward direction to accommodate insertion of the fastener 536 through the barb opening 594. Once the fastener 536 has passed through the barb opening 594, the barb 593 resiliently returns to its original position. The barb 593 includes a ledge 601 on an opposite side of the first angle 593a that faces the second chamber 591. The ledge 601 defines a surface that is oriented substantially perpendicular to the wall of the bores 537, or at a steeper angle than the first angle 593a, to prevent removal of the fastener 536 from the bores 537. When the fastener 536 is retracted toward the first chamber 590, the ledge 601 engages with a corresponding surface of the fastener 536 to block further retraction and prevent the fastener 536 from being removed from the bores 537. In this way, the barb 593 functions as a one-way retention feature that permits insertion of the fastener 536 while preventing unintended removal of the fastener 536 from the reflector 500.

[0145] While the retainer is depicted as a singular barb extending radially inward from the wall of the bores 537, it is also contemplated that the protrusion can be configured in other forms. In some examples, a retainer can include multiple barbs that extend along the wall of the bores 537. In some examples, a retainer can be configured as a thread or a series of threads extending along the wall of the bores 537.

[0146] A fastener can include sections having different diameters so that a bore with a barb can selectively allow translation of the fastener through the bore. For example, the fastener 536 includes a neck 595 having a first diameter 595a, a shank 596 having a second diameter 596a, and a head 597 having a third diameter 597a. The first diameter 595a is less than the barb opening diameter 594a. The second diameter 596a is greater than the first diameter 595a and 27QB\ 100660394.1the barb opening diameter 594a. The third diameter 597a is greater than the second diameter 596a. A lead in feature (e.g., a chamfer 598) separates the neck 595 and the shank 596. In some examples, the chamfer 598 is configured to engage the barb 593 when the fastener 536 is inserted into the bores 537. In some examples, the chamfer 598 is angled at a second angle 598a relative to an outer surface of the fastener 536. In some examples, the second angle 598a is substantially equal to the first angle 593a of the barb 593. A lip 599 separates the second portion 596 and the third portion 597.

[0147] In some examples, a fastener can include threads that allow the fastener to be rotated through a barb opening (e.g., for insertion or removal of the fastener from a bore). For example, the fastener 536 includes a thread 600 on an end of the fastener 536 opposite the head 597. The thread 600 has a minor diameter and a major diameter. The minor diameter is the diameter measured at the root of the threads of the thread 600, and the major diameter is the diameter measured at the crest of the threads of the thread 600. The minor diameter is less than the barb opening diameter 594a. The major diameter is greater than the barb opening diameter 594a and less than the diameter 537a of the bores 537. Accordingly, the thread 600 is configured to be received through the bores 537 and is configured to be blocked from translating through the barb opening 594 (e.g., without rotation). Since the minor diameter is less than the barb opening diameter 594a, the fastener 536 is configured to be rotated so that the thread 600 may pass through the barb opening 594. Correspondingly, the barb 593 can prevent dislodgement of the fastener 536 from the bores 537 during operation of the safety light 102.

[0148] To secure the fastener 536 to the reflector 500 (and thereby couple the first half 532 and the second half 534), the thread 600 is inserted through the bores 537 on an end defining the first chamber 590. Since the major diameter of the thread 600 is greater than the barb opening diameter 594a, the thread 600 engages the barb 593 (i.e., the ramped surface 593b of the barb 593). The ramped surface 593b allows the thread 600 to deflect the barb 593 radially outward. As the thread 600 advances through the barb opening 594, the barb 593 resiliently deforms (e.g., the barb opening 594 resiliently flexes (e.g., bends) in a radially outward direction) to accommodate the major diameter of the thread 600. In some examples, the barb 593 resiliently flexes in an axial direction along the bores 537. In other examples, the fastener 536 can be threaded through the barb 593.

[0149] Since the first diameter 595a of the neck 595 is less than the major diameter of the thread 600, when the thread 600 is received within the second chamber 591, the barb 593 resiliently returns to its original position. The fastener 536 is further advanced through the 28QB\ 100660394.1bores 537 (e.g., the neck 595 is advanced through the barb opening 594) until the thread 600 engages the threads of the third chamber 592. To further advance the fastener 536 (e.g., to secure the reflector 500 in the closed configuration), the fastener 536 is rotated in a first direction. As the fastener 536 is rotated in the first direction, the thread 600 threadingly engages the threads of the third chamber 592 (e.g., the threaded insert 602 coupled to the reflector 500) to advance the fastener 536 into the bores 537). The fastener 536 continues to advance through the bores 537 until the fastener 536 contacts the respective boss 538 of the reflector 500. That is, the fastener 536 is rotated in the first direction until the lip 599 contacts an end of the boss 538 to block further advancement of the fastener 536 through the bores 537.

[0150] A barb of a reflector can allow a fastener to be retained by the reflector when the reflector is in an open configuration. A first half of the reflector can retain the fastener so that the fastener can subsequently couple the first half and a second half when the reflector returns to a closed configuration. For example, still referring to FIG. 37, the fastener 536 can disengage the second half 534 (e.g., the threaded insert 602 of the third chamber 592) and be retained by the first half 532 of the reflector 500. More specifically, when the thread 600 of the fastener 536 is received in the second chamber 591 and the fastener 536 disengages the second half 534 of the reflector 500, the reflector 500 can move between the open configuration and the closed configuration (e.g., by the first half 532 and the second half 534 rotating about the axis 582). Since the third diameter 597a of the head 597 is greater than the diameter 537a of the bores 537 and the major diameter of the thread 600 is greater than the bore opening diameter 594a of the bore opening 594, the fastener 536 is retained in the bore 537 of the first half 532. As such, the ledge 601 engages the thread 600 to block the fastener 536 from escaping the bore 537 of the first half 532. Further, the lip 599 engages the boss 538 of the first half 532 to block the fastener 536 from escaping the bore 537 of the first half 532. In this way, the fastener 536 is retained by the reflector 500 when the reflector 500 is moved between the open configuration and the closed configuration.

[0151] To remove (e.g., by retracting) the fastener 536 from the bores 537, with the thread 600 threadingly engaging the threads of the third chamber 592, the fastener 536 is rotated in a second direction opposite the first direction. The fastener 536 can be further retracted (e.g., by translating the fastener 536) until the thread 600 engages the barb 593. That is, the major diameter of the thread 600 engages the ledge 601 of the barb 593 to block further retraction / translation. In this way, the ledge 601 prevents the fastener 536 from being removed from the bores 537 by translating the fastener 536. To advance the fastener 536 (e.g., the thread 600) beyond the barb 593 during retraction, the fastener 536 is rotated in the second direction 29QB\ 100660394.1so that the thread 600 threadingly engages the barb 593 and passes through the barb opening 594. Once the thread 600 is entirely received within the first chamber 590, the fastener 536 can be translated and removed from the bores 537.

[0152] In some examples, a reflector can be configured to couple to a variety of lighting devices that emit light in different ways. For example, FIGS. 38-49 illustrate a reflector 800 that is configured to couple to a safety light 702. Unless indicated otherwise, the components, functionality, and advantages of the safety light 102 in FIGS. 1-28 apply similarly to the illustrated example of the safety light 702. Correspondingly, similar components and features of the “100” series of reference numerals are denoted in the “700” series of reference numerals, unless otherwise provided. Additionally, unless indicated otherwise, the components, functionality, and advantages of the reflector 500 in FIGS. 33-37 apply similarly to the illustrated example of the reflector 800 in FIGS. 38-49. Correspondingly, similar components and features of the “500” series of reference numerals are denoted in the “800” series of reference numerals, unless otherwise provided.

[0153] In some examples, a reflector can be configured to couple to, and reflect light emitted from, different types of safety lights. Referring to FIG. 49, in some examples, a waveguide of a lens can include a surface that is not flat. Further, one surface of a waveguide can be generally angled with respect to an opposing surface of the waveguide. For example, a waveguide 780 of the lens 710 has an outer surface 779 that is substantially flat and an inner surface (e.g., a reflective surface 784) is not flat and defines a linear regression line 784A. An angle 784B between the outer surface 779 and linear regression line 784A, and thus the reflective surface 784, is approximately 40 degrees. In other embodiments, an inner surface can be angled differently with respect to an outer surface. For example, an angle between an inner surface and an outer surface may be 0 degrees (i.e., so that the surfaces are parallel), between 25 degrees and 50 degrees, or greater than 50 degrees. Correspondingly, the lens 710 is configured to transmit light between from the light element 776 and out of the outer surface 779. In that regard, the reflective surface 784 act as a light reflecting surface and the outer surface 779 acts as a light exiting surface.

[0154] In some examples, the reflective surface 784 is configured as a faceted surface having a plurality of facets 781. That is, the reflective surface 784 can define a first plurality of facets 781 A at a first angle, a second plurality of facets 78 IB at a second angle, and a third plurality of facets 781C at a third angle. Each of the plurality of facets 781 are arranged to form concave or scallop-like depressions 783 with peaks formed between adjacent depressions. In30QB\ 100660394.1this case, the plurality of facets 781 are also arranged in rows (i.e., parallel rows) running along the waveguide 780.

[0155] In some examples, a lens 710 of the safety light 702 can be recessed relative to a first cover 712 and a second cover 714 of the safety light 702. In other words, a periphery defined by the first cover 712 and a periphery defined by the second cover 714 can extend past the side surfaces (e.g., the outer surface 779) of the lens 710. In this example, a channel 840 of the reflector 800 is configured to receive one of the covers (e.g., the first cover 712). A first lip 844 defined by the channel 840 extends over the first cover 712 and a gap 713 is defined between the first lip 844 and the lens 710. In this way, a portion of the light emitted from the lens 710 is received in the gap 713. Additionally, by spacing the reflective surface 808 from the lens 710, the gap 713 limits interference of the second cover 714 on light reflected off of the reflective surface 808. Relatedly, as described above with regard to the safety light 100 and the reflective surface 200, the extent to which a reflective surface extends across a lens can be selected to control the proportion of light that is redirected by the reflector. For example, the lens 710 defines a height 820 between the first cover 712 and the second cover 714 and the reflector 800 defines a corresponding length 824. A ratio between the length 824 and the height 820 can be in the range of about 1:1 to about 1:10. In the illustrated embodiment, a ratio between the length 824 and the height 820 is about 1 :2. However, in other embodiments, a ratio can be 1 : 1 to 1 :8, 1 :2 to 1 :7, or any range therein.

[0156] In some examples, a reflective surface of a reflector can correspond to a feature of a waveguide (e.g., a shape of a waveguide). Further, in the illustrated embodiment, a proximal end 816 of the reflective surface 808 is located between the first cover 712 and the second cover 714. In this way, the reflective surface 808 is selective in that the reflective surface 808 reflects light emitted from a center portion of the lens 710 and does not reflect light emitted from an upper portion or a lower portion of the lens 710. That is, light emitted from the upper portion of the lens 710 is emitted outward from a periphery of the lens 710, light emitted from the lower portion of the lens 710 is received in the gap 713, and light emitted from the center portion of the lens 710 is reflected off of the reflective surface 808. By reducing the size of the reflective surface 808 so that it spans the center portion of the lens 710, the reflective surface 808 optimizes efficiency by reducing a size of the reflector 800, and ultimately the safety light assembly (e.g., light system). Additionally, since the waveguide 780 includes the plurality of facets 781 on the reflective surface 784, light emitted from the lighting elements 776 is diffused as the light emits from the outer surface 779 of the lens 710. The reflective surface 808 of the reflector 800 can be sized, shaped, and positioned to interact with this diffuse emission pattern 31QB\ 100660394.1produced by the waveguide 780. In some examples, the reflector 800 is configured to collect and guide the diffuse light emitted from the lens 710 so as to provide a more directed or concentrated light output from the light system. In other examples, the reflector 800 is configured to further diffuse or scatter the light emitted from the lens 710, depending on, for example, a surface characteristic of the reflective surface 808. In this way, the reflector 800 can selectively concentrate and redistribute the diffuse light produced by the plurality of facets 781 of the waveguide 780.
