[0013] Selectively attachable lighting devices, systems, and methods are described in this disclosure. According to various embodiments presented herein, a rugged lighting device may be implemented to be selectively attachable to various types of tactical equipment, such as a ballistic shield. For example, the lighting device may include a housing defining a channel, and a mounting member (e.g., at least a portion of the tactical equipment) may be received in the channel and secured within the channel using one or more adjustable fasteners of the lighting device. The channel may be defined by a first surface and an opposing second surface of the housing, and the channel may be configured to receive the mounting member. The lighting device may further include fasteners extending from the first surface and / or the second surface and configured to bias (e.g., contact, approach, or apply force) toward the mounting member, thereby securing the mounting member within the channel. The lighting device may include an optical assembly, including at least a light source, secured to the housing.

[0014] In some embodiments, a lighting device may include an appliance-mounted lighting device that provides convenient access to user controls (e.g., a communicatively coupled tape switch assembly or tailcap actuator) for selectively configuring (e.g., adjusting) the operation of the lighting device. For example, such user controls may be used to switch one or more light sources of the lighting device or to adjust the brightness and wavelength of light emitted from the one or more light sources. In one embodiment, the light source comprises one or more light-emitting diodes (LEDs), which can be selectively illuminated or dimmed to provide light of different wavelengths. In other embodiments, light sources other than LEDs may be used.

[0015] In one or more embodiments, the lighting device and / or tape switch assembly may be used in any combination with the various features described herein to form a lighting system. In certain embodiments, such lighting systems may be particularly suited for tactical applications (such as those intended for attachment to tactical equipment) or combat environments. In other embodiments, the lighting systems may be used in any environment or application.

[0016] Reference is made to the drawings for purposes of illustrating, but not limiting, the embodiments disclosed herein. FIGS. 1-8 illustrate a selectively attachable lighting device 100 (hereinafter also referred to as a "lighting device") according to several embodiments of the present disclosure. The lighting device 100 may include a housing 106. The housing 106 may include a central longitudinal axis A extending from a front portion 106a to a rear portion 106c, as shown in FIG. 3. The housing 106 may include a channel 126 defined by a first surface 142 and a second surface 144 of the housing 106. In some embodiments, the channel 126 may be defined by the first surface 142, the second surface 144, and the top surface 146, as shown in FIG. 2. In other embodiments, the channel 126 may be defined by a central portion 106b of the housing 106, as further described below. The channel 126 may be configured to receive a mounting member 101 therein, as shown in FIG. 3. In various embodiments, the first surface 142 and the second surface 144 may be opposite to each other. In some embodiments, the first surface 142 and the second surface 144 may be substantially parallel to each other. In other embodiments, the first surface 142 and the second surface 144 may be non-parallel to each other or angled with respect to each other. In some embodiments, the first surface 142 and the second surface 144 may be substantially perpendicular to the longitudinal axis A of the lighting device 100. In other embodiments, the first surface 142 and the second surface 144 may be angled with respect to each other with respect to the longitudinal axis A. The first surface 142 and the second surface 144 may be flat. In other embodiments, the surfaces may include curved surfaces. In still other embodiments, the surfaces may include irregularly shaped surfaces. In other embodiments, the first surface 142 and the second surface 144 may have a shape complementary to one or more surfaces of the mounting member 101 (shown in FIG. 3 ).

[0017] 1-8, the housing 106 may be constructed from a variety of materials. For example, the housing 106 may be constructed from a metal (e.g., aluminum, anodized aluminum alloy, steel, iron, brass, metal alloy, etc.), fiberglass, a polymer (e.g., Nitrolon®, plastic, rubber, etc.), glass, etc. For example, and without limitation, the housing 106 may be constructed from an aluminum alloy for enhanced durability (e.g., impact properties, corrosion resistance, etc.).

[0018] In some embodiments, the housing 106 may comprise a unitary structure. For example, the housing 106 may comprise a single piece manufactured using one or more of various techniques, such as injection molding, additive manufacturing, and subtractive processing. In some embodiments, the top surface 146 may comprise the bottom surface of a bridge 144 in the middle portion 106b connecting the front portion 106a and the rear portion 106c. In other embodiments, the housing 106 may comprise a modular housing including multiple pieces. For example, the housing 106 may comprise a two-piece modular housing, which may have a front portion 106a that is secured to the optical assembly 122 (see FIG. 2) of the lighting device 100 and a middle portion 106b that includes the channel 126 (see FIG. 3). In another example, the housing 106 may comprise a three-piece housing, which has a front portion 106a that is secured to the optical assembly 122, an opposing rear portion 106c, and the middle portion 106b that includes the channel 126. The central portion 106b may be disposed between the front portion 106a and the rear portion 106c. As will be appreciated by those skilled in the art, the modular housing may include any number of components.

[0019] The modular construction of the housing 106 may allow one or more components of the housing 106 to be interchangeable. For example, in one or more embodiments, the central portion 106b may be selectively interchangeable to adjust the size and / or shape of the channel 126. For example, a first central portion of the housing 106 may include a first channel having a first shape and / or size (e.g., a first set of dimensions). The first central portion may be removed from the housing 106 and replaced with a second central portion of the housing 106 including a second channel having a second shape and / or size (e.g., a second set of dimensions). The interchangeable central portion allows for versatility in the use of the lighting device 100, allowing the lighting device 100 to be attached to a variety of mounting components. As previously discussed, the channel 126 may have a variety of shapes and sizes. For example, the channel 126 may be rectangular, triangular, dome-shaped, or any other shape, as shown at least in FIGS. 1-8 . Furthermore, in various embodiments, other portions of the housing 106 may also be interchangeable. For example, the front section may be interchanged to provide different types of optical assemblies.

[0020] In one or more embodiments, the portions of the housing 106 (e.g., the front portion 106a, the middle portion 106b, and / or the rear portion 106c) may be connected to one another using various mechanisms. For example, but not limited to, the portions of the housing 106 may be connected to one another using one or more fasteners (e.g., screws, pins, nails, clamps), adhesives, or other means. Additionally, one or more electrical wires that pass through one or more portions of the housing 106 may connect these portions together to provide additional structural support.

[0021] 1-8 , the housing 106 may include one or more heat sinks 130. As shown in FIG. 3 , the front portion 106 a may include the heat sink 130. In some embodiments, the heat sink 130 may include a first heat sink and a second heat sink, where the first heat sink and the second heat sink are disposed at opposing positions on the optical assembly (e.g., on a lens or window of the optical assembly). The heat sink 130 may function as a heat sink for one or more light sources of the optical assembly 122 and / or one or more printed circuit boards (PCBs) of the optical assembly 122. In various embodiments, the heat sink 130 may be configured to dissipate heat from the one or more light sources to other portions of the lighting device 100 or to the atmosphere (e.g., the external environment).

[0022] As shown in FIG. 3 , the heat sink 130 may include one or more fins 140 (e.g., a plurality of fins 140) configured to function as a heat sink for the lighting device 100. The fins 140 may include raised surfaces relative to the surrounding surface of the housing 106, and the raised surfaces may be spaced apart from one another. In some embodiments, the fins 140 may include a first set of fins and a second set of fins at opposing positions on the lens 120 of the optical assembly 122, as shown in FIG. 2 . In one or more embodiments, the fins 140 may be substantially parallel to one another, as shown in FIGS. 1-8 . In some embodiments, the fins 140 may be separate components that are secured to the housing 106. In other embodiments, the fins 140 may be integrally molded with the housing 106 (e.g., features on the front portion 106 a). In some embodiments, the heat sink 130 may be disposed on the front portion 106 a of the housing 106 and extend the entire height of the front portion 106 a. In other embodiments, the heat sink 130 may extend only over a selected area of ​​the front portion 106a (e.g., approximately halfway up the height of the front portion 106a, as shown in FIG. 3). The fins 140 may have a variety of sizes and shapes. For example, all of the fins may be the same size. In other embodiments, one or more fins may have a different size relative to the other fins. In some embodiments, the fins 140 may form a beveled surface on the front portion 106a. One skilled in the art will appreciate that although four fins are shown on each heat sink, each heat sink in a lighting device may include any number of fins suitable for implementation.

[0023] 1 , in one or more embodiments, the lighting device 100 may include a cover 102 secured to a second end 154 (e.g., rear 106 c) of the housing 106 and configured to cover the housing 106 from the second end 154 (e.g., rear 106 c) toward the first end 152 (e.g., front 106 a). The cover 102 may then be extended around the periphery of the housing 106 such that the bezel guard 104 covers at least a portion of the optical assembly 122, as described in more detail below. The cover 102 may be attached to the second end 154 using attachment components, such as screws 150.

[0024] The cover 102 may protect the optical assembly 122 by covering at least a portion of the housing 106 and enclosing at least a portion of the optical assembly 122. For example, as shown in FIG. 2, the cover 102 may include a sacrificial lens 158 (e.g., an auxiliary lens) disposed between the optical assembly 122 (e.g., a lens of the optical assembly 122) and the external environment. In various embodiments, the sacrificial lens 158 and the lenses of the optical assembly 122 may be constructed from a variety of materials, such as, for example, glass, polycarbonate, borosilicate glass, or BOROFLOAT®. For example, but not limited to, the sacrificial lens 158 may be constructed from polycarbonate to protect the optical assembly 122, which may be constructed from a BOROFLOAT® lens. This BOROFLOAT® lens may be susceptible to damage during use of the mounting member (e.g., a Simulator (SIM) round striking the illuminator during tactical training could damage the lens of the unprotected optical assembly).

[0025] In other embodiments, the cover 102 may include a bezel guard 104 extending laterally and / or vertically from the optical assembly 122. In some embodiments, the bezel guard 104 may be a trapezoidal (e.g., frustoconical) bezel guard extending at an angle radially from the sacrificial lens 158. The bezel guard 104 may provide protection for the sacrificial lens 158 and / or the lens 120 of the optical assembly 122. For example, the bezel guard 104 may be configured to prevent the sacrificial lens 158 and / or the lens 120 from directly impacting the ground if a user drops the lighting device or the mounting member to which the lighting device is secured.

[0026] The cover 102 may be made of various materials. For example, the cover 102 may be made of an elastomeric material, which may be flexible and capable of covering the housing 106 while providing a protective layer that protects the housing 106 and / or the optical assembly 122 from the external environment. In one or more embodiments, the cover 102 may be made of, but is not limited to, a polymer, rubber, neoprene, Santoprene®, fiberglass, or the like. In various embodiments, the cover 102 may have a surface treatment or may include a texture. For example, the cover 102 may include one or more ridges configured to protect the housing 106, such as by absorbing impact forces. The ridges 128 may provide a buffer between the external environment and the housing 106. For example, when the lighting device is attached to a mounting member such as a bulletproof shield, the bulletproof shield may fall. In such a case, the cover 102 may prevent or mitigate damage to the housing 106 even if the lighting device 100 hits the ground.

[0027] As shown in FIG. 3 , the channel 126 may be defined by a first surface 142 and an opposing second surface 144 on the housing 106, and the channel 126 may be configured to receive the mounting member 101. In various embodiments, the mounting member 101 may include at least a portion of a device (e.g., a tactical device), such as a mobile structure (e.g., a vehicle), a weapons system (e.g., a firearm), a protective device (e.g., a shield), or other device or system used for tactical purposes. In some embodiments, the mounting member 101 may include a portion of a ballistic shield, and one or more fasteners may selectively secure the lighting device to a portion (e.g., an end) of the ballistic shield to provide dynamic and durable illumination while the shield is in use. For example, as further described in FIGS. 21A and 21B , if the mounting member 101 includes the upper end of the ballistic shield, the lighting device 100 may be selectively secured to the upper end to illuminate a scene while a user is holding the ballistic shield. In conventional shields, the lighting device is typically located in the center. Configuring lighting device 100 to be mounted on the edge (e.g., top) of the ballistic shield advantageously maximizes illumination of the surrounding environment while minimizing exposure of the shield and / or the user to potential hazards when the user holds the shield forward to check around corners. Additionally, because the lighting device is not centrally located, it prevents the user from being illuminated or dazzled by light reflecting off nearby surrounding surfaces.

[0028] 1-8 , in one or more embodiments, the lighting device 100 may include one or more fasteners 112 extending from the first surface 142 and / or the second surface 144, where the one or more fasteners 112 are biased toward the mounting member 101 and configured to secure the mounting member 101 to the channel 126. For example, if a first set of one or more fasteners 112 extends from the first surface 142 and a second set of fasteners extends from the second surface 144, the first set of fasteners may be biased toward the first surface 103 of the mounting member 101 and the second set of fasteners may be biased toward the second surface 105 of the mounting member 101, such that the mounting member 101 is clamped (e.g., clamped or compressed) by the first and second sets of fasteners. In some embodiments, one or more fasteners 112 may extend from first surface 142 and / or second surface 144 and be configured to bias toward mounting member 101 and bias the mounting member toward an opposing surface (e.g., second surface 144 and / or first surface 142). For example, but not limited to, one or more fasteners 112 may extend from first surface 142 and be configured to bias toward first surface 103 of mounting member 101 and bias the mounting member 101 toward second surface 144 (e.g., second surface 105 of mounting member 101 is biased toward second surface 144) to selectively secure mounting member 101 in channel 126. As another example, one or more fasteners 112 may extend from second surface 144 and be configured to contact mounting member 101 to bias mounting member 101 toward first surface 142, thereby selectively securing mounting member 101 in channel 126. In other embodiments, one or more fasteners 112 may extend from each of first surface 142 and second surface 144 and be configured to clamp mounting member 101 between the two or more fasteners to secure mounting member 101 in channel 126. In various embodiments, first surface 142 and / or second surface 144 may include elongated pads disposed thereon that are configured to contact sides of mounting member 101 to secure mounting member 101 in channel 126.

[0029] In some embodiments, the lighting device 100 may include a clamping assembly including one or more fasteners 112 configured to apply a compressive force to the mounting member 101, thereby securing the lighting device 100 to the mounting member 101. The compressive force may be applied by the one or more fasteners 112 that are translatable relative to the housing 106 toward the mounting member 101. In various embodiments, the one or more fasteners 112 may move in a direction substantially parallel to the longitudinal axis A. In other embodiments, the one or more fasteners 112 may move in a direction oblique to the longitudinal axis A.

[0030] In various embodiments, one or more fasteners 112 may each include a threaded interface configured to engage with an insert 924 having a complementary threaded interface, as shown in FIG. 9 , which may be disposed within a corresponding bore 124 (shown in FIG. 2 ) in the housing 106. For example, the bore 124 may have a substantially smooth surface, and the insert 924 may be configured to be slidably disposed within the bore 124. After the insert 924 is secured within the bore 124, the stem 114 may engage the complementary threaded interface of the insert 924 and translate within the insert 924 in response to rotation, thereby movably securing the fastener 112 within the housing 106.

[0031] In other embodiments, one or more fasteners 112 may each include a threaded interface (e.g., the stem 114 of the fastener 112 includes a plurality of threads) configured to engage a complementary threaded interface with a corresponding hole 124 of the housing 106. For example, the fastener 112 may be at least partially disposed within the hole 124 of the front portion 106a and configured to translate within the hole upon rotation of the fastener 112. For example, in one or more non-limiting embodiments, the fastener 112 may include a threaded screw. The housing 106 may include one or more screw receptacles (e.g., threaded holes) capable of receiving corresponding screws, and each screw may protrude at least partially from a surface (e.g., the first face 142 or the second face 144) of the housing 106 and be configured to be threaded through the corresponding screw receptacle. Thus, each screw may be configured to translate within the corresponding screw receptacle in response to a user rotating the screw about its axis. For example, rotation in a first direction may translate the screw in a first direction relative to the housing 106, moving the first end of the screw toward an opposing surface (e.g., the second or first surface of the channel) and / or a mounting member disposed within the channel, thereby securing the illumination device to the mounting member. Rotation in a second direction may translate the screw in a second direction relative to the housing, moving the first end (e.g., the distal end) of the screw away from the opposing surface and / or mounting member, thereby detaching the illumination device from the mounting member and removing the mounting member from the channel 126. In some embodiments, as shown in FIG. 6 , the screw includes a head 136 (e.g., a slot, hex, Phillips, Torx, square, etc., drive style) at the second end (e.g., the proximal end) of the fastener 112 that may be manipulated by a user to rotate the screw in a first direction or a second direction.

[0032] In some embodiments, the fastener 112 may include a foot 132. The foot 132 may be located at a first end of the fastener 112. The foot 132 may be movably attached to a ball of the stem 114 (e.g., body) of the fastener 112, allowing the foot 132 to articulate in any direction and to substantially contact a surface of an attachment member disposed within the channel 126. In various embodiments, the foot 132 may include a rubber pad. For example, the foot 132 may include a smooth or textured rubber surface for use in gripping an attachment member. In some embodiments, the foot 132 may be circular. In other embodiments, the foot 132 may include an elongated foot and extend along the width of the channel 126. The elongated foot may be attached to any number of stems. For example, the elongated foot may be attached to a single stem located at the center of the foot. In yet another example, the elongated foot may be attached to two stems at opposite ends of the same foot, operating independently or in conjunction. For example, a single stem may extend from first surface 142 or second surface 144 and have attached elongated pads configured to bias the mounting member to secure it within channel 126. In other embodiments, multiple stems may extend from first surface 142 or second surface 144 and have attached elongated pads configured to bias the mounting member when secured within channel 126. Thus, while fastener 112 is shown as a pair of fasteners, other embodiments are contemplated. Lighting device 100 may include any number of fasteners (e.g., a single fastener or multiple fasteners) extending from either surface forming channel 126 to secure a mounting member within channel 126.

[0033] As shown in FIG. 2 , in one or more embodiments, the second surface 144 of the housing 106 may include a facing pad 116 (e.g., an elongated pad) configured to contact the mounting member 101 (e.g., contact the surface of the mounting member opposite the fastener 112). In some embodiments, the facing pad 116 may be adjustable relative to the housing 106. In other embodiments, the facing pad 116 may be fixed relative to the housing 106. The facing pad 116 may be composed of a resilient material that can deform to conform to the shape of the surface of the mounting member it contacts. As will be appreciated by those skilled in the art, the facing pad 116 may be any shape and / or size.

[0034] As shown in FIG. 6 , in one or more embodiments, the lighting device 100 may include an optical assembly 122 secured to the housing 106. For example, the optical assembly 122 may be secured to a first end 152 of the housing 106. The lighting device 100 may include the optical assembly 122 including one or more light sources (e.g., light source 168). The one or more light sources may be disposed within the housing 106 and configured to emit light (e.g., visible light, infrared light, ultraviolet light, and / or laser light of various wavelengths) from the lighting device 100 (e.g., in a direction toward which the device is pointed). The optical assembly 122 may include one or more optical elements, such as one or more lenses and / or one or more reflectors (e.g., one or more substantially parabolic reflectors and / or reflectors of other desired shapes). The one or more reflectors may include the reflector 148. In various embodiments, the reflector 148 may include, for example, a parabolic reflector. The optical assembly 122, in combination with at least one light source, may be used to provide illumination by the lighting device 100 (e.g., projecting light generated by the light source from the housing 106 onto an external scene or environment, such as a scene that is the focus of a user of the lighting device 100). While the lighting device 100 is described primarily herein as including a reflector, other embodiments are contemplated. For example, in various embodiments, one or more lenses may be provided to direct light from the light source within the housing 106 toward an external scene. The optical assembly 122 and associated one or more light sources may be configured to project light of a variety of different wavelengths from the lighting device 100.

[0035] As previously mentioned, light source 168 may include other light sources or groups of light sources. For example, in some embodiments, light source 168 may include one or more red, green, and / or blue light sources. Light source 168 may include any desired number of light source groups, and each group may include any desired number and / or combination of light sources. Accordingly, references herein to white light sources and infrared light sources are by way of example only and not limitation.

[0036] One or more lenses (e.g., substantially flat lenses and / or lenses of other desired shapes) and / or multiple light sources may be provided on the front portion 106a (e.g., on the faceplate of the housing 106) to enable the lighting device 100 to provide light of different wavelengths. In various embodiments, the optical assembly 122 may include one or more reflectors (e.g., substantially parabolic reflectors or reflectors of other desired shapes), lenses, etc.

[0037] In one or more embodiments, the optical assembly 122 may include a total internal reflection (TIR) ​​lens, which may have a generally conical configuration. In some embodiments, the TIR lens may have an upper end (e.g., a larger end) adjacent a flat lens or window (e.g., lens 120 shown in FIG. 2 ) and a lower end (e.g., a smaller end) adjacent the light source 168. In some embodiments, the upper and lower ends of the TIR lens may be offset from the centerline of the optical assembly 122. The TIR lens, particularly its lower end, may be offset or decentered from the centerline by forming a bore in the bezel that is offset from the centerline of the optical assembly 122. Thus, when the bezel rotates relative to the optical assembly 122, the TIR lens moves through an arc.

[0038] As will be appreciated by those skilled in the art, various types of lenses other than TIR lenses may be used. Accordingly, any reference herein to the use of TIR lenses is by way of example only and is not intended to be limiting. Any type of lens and / or reflector may be used. Furthermore, any type of combination of lenses and / or reflectors may be used. For example, one or more lenses (e.g., substantially flat lenses or lenses of other desired shapes) and / or one or more reflectors (e.g., substantially parabolic reflectors and / or reflectors of other desired shapes) may be used.

[0039] In various embodiments, the lighting device 100 may include user controls. In some embodiments, the user controls may include, for example, a tape switch assembly (e.g., tape switch assembly 200 shown in FIGS. 10-18), as further described herein. In other embodiments, the user controls may include a tail cap 110. The tail cap 110 may be located on a side of the housing 106. For example, as a non-limiting example, the tail cap 110 may be located on a side of the rear portion 106c of the housing 106. In various embodiments, the user controls may include actuators (e.g., dome switch buttons, sliders, knobs, etc.), as further described with reference to FIGS. 27 and 28. User controls, such as switch assemblies and actuators, may be located on multiple sides of the lighting device 100 to allow for operation independent of a user's dominant hand.

[0040] In various embodiments, tailcap 110 may include a jack cover 138 for closing the rear opening of the tailcap when the plug is withdrawn from jack 182 of tailcap 110, as will be further described later herein. Jack cover 138 may be made of a plastic material (e.g., by molding) and in some embodiments may comprise a flexible band having a ring on one end that is secured to jack 182 and surrounds the opening, and a solid plug or cap on the other end that is configured to friction fit into the opening.

[0041] Referring to FIG. 2 , in various embodiments, the lighting device 100 may include a power source, which is described in further detail in FIG. 9 . The power source may be at least partially disposed within the housing 106. For example, the power source may be disposed in the rear portion 106 c. The housing 106 may include a cavity for enclosing the power source therein. In various embodiments, the cavity may be covered by a battery cap 108. In some embodiments, the battery cap 108 may be configured to thread onto a portion of the housing 106, thereby sealing the power source from the cavity within the housing 106.

[0042] 9 illustrates an exploded view of a lighting device 100 according to one embodiment of the present disclosure. As shown in FIG. 9, the lighting device 100 includes an optical assembly 122 including a sacrificial lens 158, a cover 102, a bezel 902, an O-ring 904, a lens gasket 906, a lens 120 (e.g., a 1.477 diameter window), a spacer 910, a reflector 148, and a light source 168, a front portion 106a (e.g., a heat sink), an insert 924, a light source printed circuit board (PCB) 920 (e.g., a light source contact board), a PCB securing screw 922 (e.g., a socket head cap screw (SHCS)), a screw 926, a screw 912 (e.g., a screw for attaching the front portion 106a to the center portion 106b), a stem 114 of a fastener 112, a foot 132 of the fastener 112, and a grille 912 for the foot 132. The assembly may include a top pad 940, a socket 936 in the foot 132, a center O-ring 930, the center section 106b, the rear section 106c (e.g., a battery housing), a control printed circuit board (PCB) 952, a rear O-ring 942, screws 944 (e.g., flat head screws (FHCS)), an O-ring 966, a contact bushing 968, the tail cap 110, a battery insulator 964, a battery contact sleeve 962, a battery cavity O-ring 960, a battery cap contact 956 (e.g., a contact with the PCB assembly), screws 958, the battery cap 108, wires 928 and 932, a washer 950, screws 948, and a power source 946 (e.g., one or more batteries).

[0043] In one or more embodiments, as described above, the lighting device 100 may include a replaceable tail cap 110. The tail cap 110 may be selectively attached to the rear portion 106c of the housing 106. In some embodiments, the tail cap 110 may be selectively attached to the housing 106 using its internal threads. In some embodiments, when the tail cap 110 is attached to the battery housing 106 (e.g., the rear portion 106c), spring contacts included in the tail cap 110 may be configured to conductively contact the rear terminals of the power source 946. The battery spring contacts may be conductively secured to a normally open circuit connection device or jack 182 (see FIG. 3) and selectively close a circuit when a switch device (e.g., the switch assembly 200 of FIGS. 10-21) is connected to the jack 182. The jack 182 is retained by the tail cap 110 and may include a rear opening for receiving and removably retaining a complementary connector (e.g., the plug 212 of the switch 216).

[0044] In various embodiments, the lighting device 100 may include a flat lens and / or a total internal reflection (TIR) ​​lens, which may be secured within a TIR housing. In one or more embodiments, the flat lens may be a substantially flat (e.g., plano-plano) lens. In other embodiments, it is contemplated that the flat lens may be implemented as any type of lens. In some embodiments, the TIR lens may be implemented as a solid optical element that utilizes total internal reflection to direct light from a particular light source (e.g., an LED or other light source) toward the flat lens. The flat lens and the TIR lens may be formed from glass, plastic, or any other material that is substantially transparent to the wavelengths of light produced by the light source. Indeed, any combination of materials and lens types may be used.

[0045] The light source PCB 920 (e.g., an FR-4 PCB) may be attached to the housing 106 (e.g., the front portion 106a or the heat sink 130) using screws 926. The light source 168 is attached to a metal core substrate, which may have one or more light sources (e.g., LEDs and / or other types of light sources) attached to it. In some embodiments, such LEDs may be implemented using one or more dies (e.g., multi-die LEDs). In some embodiments, one or more white light LEDs and one or more infrared LEDs may be attached to the metal core substrate and communicatively connected to the light source PCB 920. The heat sink 130 may function as a heat sink for the one or more light sources (e.g., the light source 168) attached to the front portion 106a. As such, the heat sink 130 may dissipate heat generated by the one or more light sources to other portions of the lighting device 100 and / or to the surrounding air.

[0046] The controller PCB 952 may be attached to the housing 106. For example, without limitation, the controller PCB 952 may be attached to the rear section 106c of the housing 106 using screws 944, thereby allowing for easy replacement of the center section 106b. In some embodiments, the controller PCB 944 may be implemented as two stacked PCBs. The light source PCB 920 and / or the controller PCB 944 may be electrically connected to one or more batteries used to form the power source 946, which is located in a cavity defined by the rear section 106c of the housing 106. The controller PCB 952 may include circuitry for determining which, if any, of the one or more light sources to activate and for activating the selected light sources. Thus, the controller PCB 952 may receive power from the one or more batteries that form the power source 946 and provide power to the selected light sources. One or more additional electrical connections may be implemented using appropriate springs, wires, or other techniques, as will be understood by those skilled in the art. For example, wires 928 and 932 may be used to provide a communication connection between one or more components of the lighting device, such as any PCBs, light sources, etc. In some embodiments, wires 928 and 932 may extend from rear portion 106c to front portion 106a through central portion 106b.

[0047] In some embodiments, the structural components of lighting device 100 may be formed from metals such as aluminum, magnesium, or steel, while in other embodiments, these structural components may be formed from durable plastics such as polycarbonate or acrylonitrile butadiene styrene (ABS), or any other desired material.

[0048] 10-17 , various views of a tape switch assembly 200 are shown in accordance with several embodiments of the present disclosure. In various embodiments, the tape switch assembly 200 (also referred to hereinafter as a “switch assembly”) may include a switch device 216 (also referred to hereinafter as a “switch”) configured to selectively adjust an operational mode of the light source 168 of the lighting device 100, a housing 202 configured to house the switch 216 therein, a pin 220, and an actuator 204. The actuator 204 includes a slot 222 configured to receive the pin 220 and connect the actuator 204 to the housing 202. In response to a depression by a user, the actuator 204 may then translate relative to the pin 220 to activate the switch 216, thereby activating the lighting device 100.

[0049] In some embodiments, the switch device 216 may include a flexible cable 210 having a first end attached to the body of the switch 216 (e.g., flexible enclosure 230) and a second end attached to the plug 212, and the cable 210 may include two conductors connecting electrodes of the switch 216 to two conductive contacts of the plug 212. In some embodiments, one of the plug contacts comprises a substantially cylindrical outer longitudinal conductive sheath that, when inserted through an opening in the jack 182 of the tail cap 110, completes a conductive path to one electrode terminal of a light-emitting element (e.g., light source 168). For example, the outer plug contact may engage a jack spring contact of the jack 182, which may be conductively coupled to a conductive battery housing in the rear section 106c. The other plug contact may be provided by an inner longitudinal conductive sheath that contactingly engages a longitudinal conductive pin of the jack 182, which may be conductively secured to a battery spring contact that contactingly engages a rear terminal of the power source 946. The other terminal of the power source 946 is conductively connected to the other terminal of the light emitting element, so that when the switch 216 is actuated with the plug 212 inserted into the jack 182, the switch 216 may connect circuitry with the battery 946 and illuminate the light emitting element. In some embodiments, the jack cover 138 may include one or more radially formed protrusions or appendages formed around the periphery of the jack cover 138 that a user may use to remove the jack cover 138 from the rear opening of the tail cap 110.

[0050] As previously mentioned, tailcap 110 may include jack cover 138 for closing the rear opening of the tailcap when plug 212 of switch device 216 is removed from jack 182. Jack cover 138 may be manufactured from a plastic material, for example by molding, and may include a flexible band with a ring at one end that is secured to jack 182 and surrounds the opening, with the free end of the flexible band having a solid plug or cap configured to be inserted into the opening with a friction fit.

[0051] In one or more embodiments, the lighting device 100 may include a switch assembly 200. In some embodiments, the switch assembly 200 may be located in a position that is easily accessible to a user, allowing the user to easily control the light generated by the lighting device 100 while operating the device. The switch assembly 200 may also be located remotely from the lighting device 100, allowing the user to conveniently operate the lighting device 100 while operating the device to which the lighting device 100 is attached. For example, if the lighting device 100 is attached to a ballistic shield, the user may use the switch assembly 200 to operate the lighting device 100 without having to reach outside the area protected by the ballistic shield. The user can easily turn the lighting device 100 on and off, increase or decrease the brightness of the light, switch light sources, etc., while holding the grip of the shield by operating the switch assembly with their thumb or fingers. The switch 216 may include one or more actuators. For example, in some embodiments, the actuators may include a first actuator for a momentary switch and a second actuator for a constant switch for switch 216 .

[0052] The lighting device 100 and the switch assembly 200 may be communicatively coupled to exchange information and / or data via wired or wireless communication in order to operate the lighting device 100 using the switch assembly 200 or to provide feedback to the switch assembly 200. In some embodiments, the lighting device 100 and the switch assembly 200 may be communicatively coupled using a wired connection, such as a cable 210, which may provide, among other things, electrical communication between the lighting device 100 and the switch assembly 200. The switch assembly 200 may include a plug 212 configured to be received in a jack 182 of the lighting device 100. The cable 210 may conductively connect plug contacts of the plug 212 to tape switch electrodes disposed within a switch 216.

[0053] In other embodiments, the lighting device 100 and the switch assembly 200 may be communicatively coupled using a wireless connection enabled by a communications component. In some embodiments, the communications component may be implemented as, for example, a connector for interfacing one or more electronic components to an external device, a network interface component (NIC) configured for communication with a network and other devices within the network, or other configuration. In various embodiments, the communications component may include one or more wired or wireless communications components, such as a wireless local area network (WLAN) component based on the IEEE 802.11 standard, a wireless broadband component, an Ethernet connection, a Bluetooth® connection, a mobile cellular component, a wireless satellite component, or any other type of wireless communications component. Other wireless components (e.g., radio frequency (RF), microwave frequency (MWF), and / or infrared frequency (IRF) components, etc.) may be configured for communication with a network, a modem, a LAN card, or any combination thereof. For example, the communications component may include an antenna used for wireless communications purposes. In other embodiments, the communications component may be configured to interface with an Ethernet device, a DSL (Digital Subscriber Line) modem, a Public Switched Telephone Network (PSTN) modem, or various other wired and / or wireless network communications devices configured for communication with a network.

[0054] In one or more embodiments, the housing 202 has a curved (e.g., arcuate) bottom surface 214 that allows the housing 202 to be secured to a complementary curved surface, such as the cylindrical grip portion of a ballistic shield, as shown in FIG. 21A . In other embodiments, the bottom surface 214 of the switch assembly 200 may be flat or have any shape that is complementary to the surface of the device to which the switch assembly 200 is attached. In various embodiments, the housing 202 may have a slot defined by the bottom surface 214 of the housing 202 to allow the switch 216 to be easily inserted and removed from the housing 202. The slot may allow the bottom surface of the switch 216 to function as part of the curved bottom surface 214 that is attached to the device. In one or more embodiments, the switch assembly 200 may include a fastening component 208. The fastening component 208 may include, for example, an adhesive layer for adhering the switch assembly 200 to the surface of the device. In some embodiments, the remote switch assembly 200 may be attached directly to the device using an adhesive. In other embodiments, an adhesive may be used to adhere hook and loop strips to the switch assembly 200, thereby removably attaching the switch assembly 200 to a device.

[0055] It will be appreciated that switch assembly 200 may be removably mounted to any surface of the equipment that is convenient for the operator. For example, in the exemplary case where the device includes a ballistic shield, switch assembly 200 may be removably mounted anywhere on the grip or back of the shield.

[0056] It will be appreciated that the detachable construction of switch assembly 200 facilitates field replacement of damaged tape switches or cables and also allows for connection to different types of remote switches. Additionally, switch devices are provided with different cable lengths so that an operator may select a switch device having a cable length that is optimal for a particular tactical situation.

[0057] The housing 202 may include tactile indicia indicating the pressure actuation portion of the switch device 216, such as raised horizontal borders or bars spaced longitudinally along the actuation or pressure-sensitive length of the flexible enclosure (e.g., switch electrode) to indicate the appropriate location where an operator should apply pressure to actuate the momentary switch.

[0058] In various embodiments, housing 202 may include laterally extending grooves 206 or other tactile indicia near the front and rear of the housing to facilitate the application of flexible cable ties (e.g., zip ties) to more securely secure tape switch assembly 200 to a ballistic shield or other object. For example, housing 202 may include a pair of grooves 206 located on opposite ends of housing 202.

[0059] 18 , a configuration of a switch assembly 200 according to one embodiment of the present disclosure is shown. In various embodiments, the switch assembly 200 may include a remote switch assembly. In some embodiments, the switch assembly 200 may include spaced-apart electrodes within a flexible enclosure 230 (e.g., a button), and an operator may manually apply pressure to press the electrodes together into electrical contact. When the operator ceases to apply such pressure, the electrodes may return to their spaced-apart state.

[0060] In various embodiments, the switch assembly 200 may include an actuator 204 configured to be depressed by a user such that a protrusion 226 on a bottom surface 228 of the actuator 204 abuts a flexible enclosure 230 of the switch 216 to activate the lighting device 100, as described further below with reference to FIG. 20 . The housing 202 of the switch assembly 200 may include an opening to allow a portion of the actuator to pass through and be forced against the top of the flexible enclosure to activate the lighting device 100.

[0061] 19 illustrates an exploded perspective view of a switch assembly according to one embodiment of the present disclosure. As previously described, the tape switch assembly may include an actuator 204, a housing 202, a pin 220, and a fastener 208. The switch 216 is slidably disposed within the housing 202, and may be attached to an appliance located remotely from the lighting device 100. For example, a user may slide the switch 216 through an opening in a first end of the housing 202 to at least partially position the switch 216 within the housing 202.

[0062] FIG. 20 illustrates a left-side cross-sectional view of the switch assembly 200 of FIG. 10 in accordance with one embodiment of the present disclosure, taken along section 20-20 in FIG. 10 . As shown in FIG. 20 , a user's operation may include depressing the actuator 204 in direction 213. The slot 222 may be elongated to allow the actuator 204 to be depressed regardless of the location at which a force is applied to the top surface of the actuator 204. For example, when a user depresses the first end 242 of the actuator 204, the actuator 204 may actuate by pivoting primarily about the pin 220 and moving substantially along the direction 213. On the other hand, when a user depresses the second end 244 of the actuator 204, the actuator may translate downward and move substantially parallel to the direction 213. Thus, an interaction area along the surface of the actuator 204 is enlarged due to the pin 220 being disposed within the elongated slot 222. As the actuator 204 translates downward, it moves relative to the pin 220, such that when the actuator 204 is not depressed, the pin 220 is at position X within the slot 222, and when the actuator 204 is depressed, the pin 220 is at position X within the slot 222. In various situations, an operator may need to quickly activate the lighting device 100, especially when lighting conditions are poor. Because the actuator 204 covers most of the top surface of the switch 216 and can be depressed regardless of the position of the applied force, the user can easily activate the lighting device 100 without requiring high precision or unnecessary distraction from the surrounding environment.

[0063] In one or more embodiments, the force required to depress the actuator 204 may be reduced by a protrusion 226. The protrusion 226 may extend from a bottom surface 228 of the actuator 204. In some embodiments, the protrusion 226 may extend centrally along the bottom surface 228. When a user depresses the actuator 204, the protrusion 226 may press against the switch 216. The switch 216 may be constructed of an elastomeric material such that a top of a flexible enclosure 230 of the switch 216 may be depressed when pressed by the protrusion 226. In some embodiments, the switch 216 may include tape switch electrodes that are enclosed in the body of the switch 216 and are squeezable together.

[0064] In various embodiments, the body of the switch 216 may be manufactured from an elastomeric material such as neoprene. The body of the switch 216 and the housing 202 may be fabricated using a variety of techniques, such as molding, three-dimensional printing, etc.

[0065] In one or more embodiments, the actuator 204 may be secured to the housing 202 at a first end 242 by the lip 232 abutting against an engagement surface 236 of the housing 202, and at a second end 244 by the pin 220 passing through a pair of holes in the housing 202 and a slot 222 in the actuator 204.

[0066] 21A and 21B show various perspective views of a lighting device 100 and a switch assembly 200 mounted to a device 2101 (e.g., a ballistic shield and / or other suitable type of device) having a mounting member 2100, according to one embodiment of the present disclosure. In some embodiments, the lighting device 100 may be mounted to the ballistic shield at a first location (e.g., the mounting member 2100) using a clamp assembly including a movable catch 112 and a facing pad 116. The switch assembly 200 may be mounted to the device 2101 at a second location. The remote switch assembly 200 may be located in a convenient location for a user of the device 2101 to facilitate the user's control of the lighting device 100 while operating the device 2101. The cable 210 of the switch assembly 200 may be of any length, thereby allowing the switch assembly 200 to be positioned at any location on the device 2101. In some embodiments, the cable 210 may be attached (by sticking, gluing, fastening, etc.) to a surface of the ballistic shield to prevent it from getting caught on the user and / or the external environment.

[0067] In various embodiments, the housing 202 of the switch assembly 200 may be attached to the grip or handle of the device 2101 using, for example, an adhesive (rubber cement, hook-and-loop fasteners, etc.). The grip provides a convenient location for a user's hands to operate the device 2101, allowing the user to easily operate the remote switch 216 with their thumb or fingers while holding the grip. In other embodiments, the grip may include one or more switches that may be connected to the lighting device 100 to control the lighting device 100.

[0068] 22-25 illustrate various views of the cover 102 according to multiple embodiments of the present disclosure. In one or more embodiments, the lighting device 100 may include the cover 102 secured to the second end 154 (e.g., rear portion 106c) of the housing 106 and configured to cover the first end 152 (e.g., front portion 106a) from the second end 154 (e.g., rear portion 106c). The cover 102 may also cover the housing 106, and as described in more detail below, the bezel guard 104 may extend to cover at least a portion of the optical assembly 122. The cover 102 may be attached to the housing 106 using, for example, the screw 150 shown in FIG. 8. The screw 150 may extend through a hole 2502 shown in FIG. 23 to attach the cover 102 to the housing 106.

[0069] The bottom surface 2504 of the cover 102 may be positioned opposite the top surface of the housing 106. The top surface 2506 of the cover 102 may include the raised portions 128, as described above with reference to FIGS. 1-8. The raised portions 128 may include one or more raised portions on the top surface 2506, with grooves disposed between the raised portions. In some embodiments, the raised portions 128 may include vertical ridges that are substantially parallel to the longitudinal axis A and each other on the housing 106 when the cover 102 is positioned over the housing 106. In other embodiments, the raised portions 128 may include horizontal ridges that are perpendicular to the longitudinal axis A and substantially parallel to each other on the housing 106 when the cover 102 is positioned over the housing 106. The raised portions 128 may include various designs, such as parallel lines, zigzag patterns, concentric or adjacent circles, rectangles, triangles, and other polygons.

[0070] The cover 102 may be arranged to cover at least a portion of the housing 106 and may be configured to enclose and protect at least a portion of the optical assembly 122. For example, the cover 102 may include a sacrificial lens 158 in the optical assembly 122, which is arranged between the lens of the optical assembly 122 and the external environment. If the cover 102 is damaged, the cover 102 may be easily replaced, as shown in FIG. 26 .

[0071] 26 illustrates a securing mechanism for securing the cover 102 to the lighting device 100, according to one embodiment of the present disclosure. The cover 102 may be attached to the housing 106 using various types of attachment components. For example, the cover 102 may be attached to the second end of the housing 106 using one or more pins, screws 150, notches, tabs 2602, etc. In some embodiments, as shown in FIG. 26 , the tabs 2602 may include oval-shaped tabs that pass through complementary holes in the cover 102, thereby securing the cover 102 to the housing 106.
