- the plus button 48 changes the brightness setting of the primary light 18 up to the next discrete interval brightness setting as set forth in Table A below (i.e., the settings 1, 2, 3, 4, or 5). If the brightness setting is already at 5, the mode will remain unchanged. For example, if the current brightness setting is at mode 3.6 (340 lumens), a short tap of the plus button 48 will change the setting to mode 4.0 (500 lumens). If the current brightness setting is at mode 1.0 (5 lumens), a short tap of the plus button 48 will change the setting to mode 2.0 (100 lumens).
- a short tap e.g., a press and release within one second
- the minus button 46 changes the brightness setting of the primary light 18 down to the next discrete interval brightness setting as set forth in Table A below. If the setting is already at mode 1, it will remain unchanged. For example, if the current brightness setting is at mode 3.6 (340 lumens), a short tap of the minus button 46 will change the setting to mode 3.0 (250 lumens). If the current brightness setting is at mode 2.0 (100 lumens), a short tap of the minus button 46 will change the setting to mode 1.0 (5 lumens).
- a long hold of the plus button 48 causes the brightness setting to incrementally rise through the settings set forth in Table A below as long as the plus button 48 is pressed. For example, if the current setting is mode 1.0, the brightness will progress from 1.0 to 1.1, 1.2, 1.3, etc. for as long as the button is pressed.
- the primary light 18 will remain on the lumen setting that is set at the time the button is released. If setting 5.0 is reached, the primary light 18 will blink three times, indicating to the operator that the light will not increase lumen settings any further. At that point, the light will remain at brightness setting 5.0.
- a long hold of the minus button 46 causes the brightness setting to incrementally descend through the settings set forth in Table A below as long as the minus button 46 is pressed. For example, if the current setting is mode 5.0, the brightness will progress from 5.0 to 4.9, 4.8, 4.7, etc. for as long as the button is pressed.
- the button is released, the primary light 18 will remain on the lumen setting that is set at the time the button is released. If setting 1.0 is reached, the primary light 18 will blink three times, indicating to the operator that the light will not decrease lumen settings any further. At that point, the light will remain at brightness setting 1.0.
- buttons 46 , 48 When the primary light 18 is on, pressing both of the minus and plus buttons 46 , 48 for any time duration greater than 1 second results in a change in the mode of the strobe setting. The status of this mode will be recorded in tandem with the brightness setting to be returned to upon the next activation. For example, if the primary light 18 is set to be on continuously, pressing both buttons may activate a strobe setting in which the light flashes at predetermined intervals.
- the primary light 18 will start to blink (e.g., 0.5 seconds off then 0.5 seconds on) for three times in a three second time period.

- The present disclosure generally relates to firearm accessories and more particularly to firearm accessory lights, mounts, and battery arrangements.
- Firearm accessories use various types of mounting systems for mounting the accessories on firearms. For example, some rifles include a handguard or other structure having one or more accessory rails thereon, and some handguns include a rail under the barrel extending forward of the trigger guard. Firearm accessories have different types of mounts configured to interface with such rails to mount the accessories on the rails. In order to prevent forward movement of the firearm accessory when mounted, a protrusion on the accessory may extend upward into a recess on the firearm rail. The protrusion is often in a fixed position on the accessory so that the accessory may only be mounted longitudinally on the rail in a single position. If the protrusion is adjustable, removal of the accessory from the firearm may be necessary to adjust the protrusion to a new position.
- Electronic firearm accessories such as lights and lasers usually include some type of switch to enable the user to turn the accessory on or off or to otherwise change an operation (e.g., mode) of the accessory. Firearm accessories with lights or lasers typically include a light or laser intended to assist the user in aiming the firearm. Such light or laser is oriented when mounted on the firearm so that it emits light in a direction aligned with the barrel of the firearm. Many electronic firearm accessories include a removable battery to power the light or laser. With many electronic firearm accessories, the light must be unscrewed from the accessory in order to remove and replace the battery. Many other types of electronic firearm accessories require the user to dismount the accessory from the firearm in order to remove and replace the battery.

- Referring to
FIGS. 1 and 2 , a firearm accessory of the present disclosure is generally indicated by thereference number 10. In the illustrated embodiment, thefirearm accessory 10 is an electronic firearm accessory in the form of a light or illuminator for illuminating an area in front of the firearm (e.g., to assist in acquiring a target and/or aiming the firearm at the target) and for illuminating an area beneath the firearm (e.g., to assist a user holding the firearm to see the environment or a travel path in front of them). It will be understood that the firearm accessory can be a different accessory such as a laser, or a light plus laser combination, or a non-electronic accessory without departing from the scope of the present invention. In particular, certain aspects of the present disclosure may be used with types of firearm accessories other than lights. For example, the configuration of the mount, lugs, and lug receivers of thefirearm accessory 10 described below may be used with other types of firearm accessories. The configuration of the battery receptacle and battery door, as described in more detail below, may also be used with other types of firearm accessories that are battery powered. - The light 10 is configured for mounting on a firearm by connecting to a rail of the firearm. Accessory mounting rails are commonly provided on long guns such as rifles and shotguns, as well as on handguns such as pistols and revolvers. The illustrated
light 10 is intended for mounting on an accessory rail of a handgun or pistol in front of a trigger guard of the handgun. Although the light 10 is discussed herein as being intended for a handgun or pistol, it will be appreciated that the light can be mountable on an accessory rail of a different type of firearm without departing from the scope of the present invention. An example handgun F including an accessory mounting rail R is shown inFIG. 21 . The accessory rail R extends forward of a trigger guard TG along a rail axis RA that is generally parallel to a barrel axis BA of the handgun. A length of the accessory rail R extends along the rail axis RA. The illustrated accessory rail R is shown as an integral part of the handgun F, but in other embodiments the accessory rail can be separate from and mounted on the handgun. Opposite left and right sides of the rail R define ridges R′ extending along the rail axis RA that are configured for retainably mounting the light 10 on the rail. A recess G (e.g., slot or groove) in the bottom of the rail R extends transverse to the rail axis RA between the opposite sides of the rail R and is used to locate and prevent movement of the accessory along the rail. The position of the recess G along the length of the rail R is not standard across all brands of handguns. In other words, a distance D1 from the recess R to the trigger guard TG is different on various handguns. Some accessory rails may have multiple recesses spaced along the length of the rail at different distances from the trigger guard (e.g., the accessory rail shown inFIG. 22A ). It is desirable to mount the light 10 on the handgun F close to the trigger guard TG, so that switches of the light may be conveniently actuated by a user's hand holding the handgun. Further, different types of accessory rails may have recesses G of different widths (i.e., the distance across the recess G in a direction aligned with the rail axis RA). For example, accessory rails known as Picatinny rails may have a recess G with a width that is larger than accessory rails known as Weaver rails or accessory rails on GLOCK branded firearms. As will become apparent, the light 10 is designed to be used with a wide range of handguns having rails of different constructions (e.g., different rail recess locations and widths) and is configurable to enable adjustable mounting on the handgun rail R to customize the location of the light with respect to the trigger guard TG. - Referring now to
FIGS. 1 and 2 , the light 10 generally includes ahousing 12,switch assemblies 14 a-b (broadly, “actuators”) at a rear of thehousing 12, and abattery door 16 pivotably mounted to a bottom of thehousing 12. Thehousing 12 has a front 12 a, a rear 12 b (FIG. 2 ), a top 12 c, a bottom 12 d, and opposingsides 12 e-f extending between the top 12 c and the bottom 12 d and from the rear 12 b to the front 12 a. A width of thehousing 12 extends between the opposingsides 12 e-f, and a length extends between the front and rear 12 a-b. The width of thehousing 12 is less than the length, providing thehousing 12 with an elongate shape. Other shapes and constructions can be used without departing from the scope of the present invention. Thehousing 12 has an accessory axis AA (FIGS. 4, 5, and 22 ) along which the length of the accessory rail R extends when the light 10 is mounted on the handgun F. When the light 10 is mounted on the rail R, the accessory axis AA of thehousing 12 is generally parallel with the barrel axis BA and rail axis RA of the firearm, as shown inFIG. 22 . - The
housing 12 supports a primary light 18 (broadly, “first light source”) and a secondary or path light 20 (FIG. 6 ) (broadly, “second light source”). Theprimary light 18 emits light outward from a front of thehousing 12 to assist a user in aiming a firearm to which the light 10 is mounted, and the path light 20 emits light downward and forward from thehousing 12 to assist a user in seeing a travel path of the user. Thehousing 12 includes amount 22 configured to mount and support thehousing 12 on the accessory rail R of the handgun F, as described in more detail below. - Referring to
FIG. 1 , light from theprimary light 18 is emitted from thehousing 12 through afront opening 24 defined by afront surface 26 of thehousing 12. Light from the path light 20 is emitted from thehousing 12 through a bottom opening 28 (FIGS. 3 and 6 ) defined by abottom surface 30 of thehousing 12. Theprimary light 18 is oriented with respect to thehousing 12 to emit light away from the front 12 a of thehousing 12 in afirst direction 32 that is aligned with the accessory axis AA (FIG. 5 ). Thefirst direction 32 is generally perpendicular to thefront surface 26 of thehousing 12. Thefirst direction 32 is aligned with the accessory axis AA of the light 10, as shown inFIG. 22 , which is positioned below and parallel to the barrel axis BA of the firearm F. Thus, the light emitted from theprimary light 18 in thefirst direction 32 illuminates objects or targets in front of the barrel of the firearm F to assist a user in aiming the firearm F. - The path light 20 (
FIG. 6 ) is oriented with respect to thehousing 12 to emit light away from the bottom 12 d of thehousing 12 in asecond direction 34, which is shown best inFIG. 5 . Thesecond direction 34 is generally perpendicular to thebottom surface 30 of thehousing 12. Thesecond direction 34 is positioned at an angle X with respect to thefirst direction 32. The angle X may be any non-zero angle. As shown inFIG. 5 , the angle X is an acute angle between 0 and 90 degrees. In some embodiments, the angle X may be any angle between 45 to 90 degrees, between 60 to 90 degrees, between 65 to 75 degrees, or approximately 70 degrees. Thebottom surface 30 of thehousing 12 extends away from thefront surface 26 at an angle that is the difference of 180 minus X. As shown inFIG. 5 , this angle is greater than 90 degrees and less than 180 degrees. In at least some embodiments, the angle may be 90 degrees such that thesecond direction 34 is generally perpendicular to thefirst direction 32. Thehousing 12 and position of the path light 20 within thehousing 12 may be configured so that the angle X is any suitable value. As shown inFIG. 5 , the light emitted from the path light 20 in thesecond direction 34 extends downward from thehousing 12 and slightly forward from thehousing 12. Thus, the light emitted from the path light 20 in the second direction illuminates the ground beneath and in front of the light 10 to assist a user in seeing a travel path in front of the user and navigating any obstacles that may be in the user's travel path. - As shown in
FIG. 3 , theprimary light 18 includes fourLEDs 18 a-d arranged in a rectangular or square pattern generally in the center of thefront opening 24. While in the illustrated embodiment, theprimary light 18 consists of fourLEDs 18 a-d, theprimary light 18 may consist of any number of LEDs. Further, theprimary light 18 may consist of light sources other than LEDs without departing from the scope of the present invention. For example, the primary light may be a laser. TheLEDs 18 a-d are arranged so that the combined light emitted from the LEDs is primarily directed in thefirst direction 32 described above and shown inFIG. 1 . Theprimary light 18 is positioned between the top 12 c and the bottom 12 d of thehousing 12, and may be positioned at approximately a midpoint between the top 12 c and bottom 12 d. Theprimary light 18 is further positioned between the opposingsides 12 e-f of thehousing 12, and may be positioned at approximately a midpoint between the opposingsides 12 e-f. TheLEDs 18 a-d are mounted on a printed circuit board (“PCB”) 36 that is spaced behind thefront surface 26 of the housing and behind afront lens 38, which protects theLEDs 18 a-d from damage. Thefront opening 24 of thehousing 12 through which light emitted from theprimary light 18 may pass extends substantially across the entire width and height of the front 12 a of the housing such that thefront surface 26 of thehousing 12 has a substantially small surface area, as best seen inFIG. 1 . - The path light 20 (
FIG. 6 ) is positioned above arecess 40 of thebottom surface 30. As shown inFIGS. 3 and 12 , therecess 40 and path light 20 are positioned below theprimary light 18. Specifically, therecess 40 and path light 20 are positioned below theprimary light 18 to the extent that when viewing thehousing 12 from the front, as shown inFIG. 3 , therecess 40 and path light 20 are vertically aligned with theprimary light 18 across the width of thehousing 12 when the top 12 c is generally horizontal and positioned above the bottom 12 d. The path light 20 is positioned longitudinally forward of theprimary light 18, as shown inFIG. 12 . The path light 20 is generally positioned at a midpoint of thehousing 12 across the width of thehousing 12, as shown inFIG. 6 . The configuration of therecess 40 and thehousing 12 adjacent the path light 20 may cause light emitted from the path light 20 to be reflected so that the light as emitted from thebottom opening 28 of the housing is primarily directed in the second direction 34 (FIG. 5 ). While in the illustrated embodiment, the path light 20 is a single LED, the path light 20 may consist of any number of LEDs. Further, the path light 20 may consist of light sources other than LEDs without departing from the scope of the present invention. For example, the path light may be a laser. The path light 20 is mounted on a PCB 42 (FIG. 6 ) that is spaced behind thebottom surface 30 and behind abottom lens 44, which protects the path light 20 from damage. - The
switches 14 a-b, shown inFIG. 2 , are used to turn theprimary light 18 on and off. As shown inFIG. 22 , theswitch 14 b is configured to be selectively positioned adjacent the trigger guard TG (e.g., outboard a right side of the trigger guard) when the light 10 is mounted on the accessory rail R. Theother switch 14 a (not shown inFIG. 22 ) is configured to be positioned adjacent the opposite side of the trigger guard TG asswitch 14 b. One of theswitches 14 a-b may be conveniently actuated by the trigger finger of the user without significantly adjusting the user's hand on the grip of the handgun F. For example, if the user grips the handgun F with his or her right hand, theswitch 14 b may be actuated to turn theprimary light 18 on or off, and if the user grips the handgun F with his or her left hand, theswitch 14 a may be actuated. As explained in further detail below, theswitches 14 a-b can be actuated by pressing them inward to turn theprimary light 18 on and off. Aminus button 46 onside 12 e of the housing (FIG. 1 ) may be pressed to decrease the brightness of theprimary light 18, and aplus button 48 onside 12 f of the housing (FIG. 2 ) may be pressed to increase the brightness of theprimary light 18, as described in more detail below. Other functions of theswitches 14 a-b andbuttons - Referring now to
FIGS. 7-10 , abattery compartment 50 andbattery door 16 of the light 10 are described in more detail. Thebattery compartment 50 is defined by thehousing 12 and is configured to receive and retain abattery 52 that powers theprimary light 18 and path light 20, in addition to a control system of the light 10 as described in more detail below. Thebattery 52 may be any type of suitable battery, including a lithium-ion rechargeable battery (e.g., a Li-Ion 16340 battery) or lithium polymer battery. Thebattery compartment 50 may further be configured to receive one or more batteries or a battery pack (broadly, “power source”). Thebattery compartment 50 is accessible through abattery opening 54 in the bottom of thehousing 12. Thebattery door 16 is pivotably joined to thehousing 12 at a forward end of thebattery door 16 via apin 55 that is received by aligned openings of thehousing 12 andbattery door 16. Thebattery door 16 is movable between the closed position (shown inFIGS. 1-6 ), in which it covers thebattery opening 54, and an open position (shown inFIGS. 7-9 ), in which thebattery compartment 50 is accessible through thebattery opening 54. Thebattery door 16 includes aretainer 56 at its rearward end that is operable to releasably engage a portion of thehousing 12 to retain thebattery door 16 in its closed position. As shown inFIG. 10 , theretainer 56 has an inverted U-shape with oneleg 56 a extending upward from the rear end of thebattery door 16 and afree leg 56 b that is resiliently deformable toward theleg 56 a. As best shown inFIG. 12 , alatch 58 on thefree leg 56 b engages akeeper 60 on thehousing 12 when thebattery door 16 is in its closed position. Theretainer 56 includes aledge 56 c extending outward from thefree leg 56 b to provide structure that a user may push to move thefree leg 56 b toward theleg 56 a and release thelatch 58 from thekeeper 60 to move thebattery door 16 to its open position. As thebattery door 16 is moved from its open position to its closed position, a ramped surface of thelatch 58 engages thehousing 12 below thekeeper 60 deflecting thefree leg 56 b toward theleg 56 a. When thelatch 58 is above thekeeper 60, thefree leg 56 b snaps back into its original position and thelatch 58 engages thekeeper 60 to maintain thebattery door 16 in its closed position. Other types of releasable retention structures may be used to retain thebattery door 16 in its closed position and be releasable to allow a user to open thebattery door 16. In particular, thebattery door 16 may be releasable without the use of a tool. Further, thebattery door 16 may be opened and closed, and thebattery 52 removed from thebattery compartment 50, without removing or altering any other components of the light 10 (e.g., without removing a light body or head of the light). In the embodiment shown inFIG. 7 , thebattery door 16 is rotatable at least approximately 90 degrees from its closed position to its open position to allow a user full access to thebattery compartment 50 to remove and replacebattery 52. - As shown in
FIG. 5 , thepin 55 about which thebattery door 16 pivots is transverse to the accessory axis AA of the light 10. Thepin 55 is also positioned adjacent the bottom 12 d of thehousing 12 and near the front 12 a of thehousing 12. The position of thepin 55 and configuration of thebattery door 16 allows the door to open and close without dismounting the light 10 from the firearm F or otherwise altering the manner in which the light 10 is mounted to the firearm F. When thebattery door 16 moves to its open position, shown inFIG. 7 , it rotates away from the components of the firearm F to which the light 10 is mounted (e.g., it rotates away from the trigger guard TG shown inFIG. 22 ). This allows thebattery 52 to be changed in a relatively quick manner without the need to dismount, remount, and realign the light 10 on the firearm F. - Referring to
FIG. 10 , thebattery door 16 includes alower wall 16 a and twoside walls 16 b-c extending upward from thelower wall 16 a. The configuration of thelower wall 16 a andside walls 16 b-c allows thebattery door 16 to lie flush with thesides 12 e-f of the housing and theswitches 14 a-b, as shown inFIGS. 2 and 5 . As shown inFIGS. 2 and 6 , when thebattery door 16 is in its closed position, theretainer 56 is largely hidden by thehousing 12 with only a portion of theledge 56 c accessible to open thebattery door 16. Theledge 56 c is positioned between theswitches 14 a-b in a location where it does not impede operation of the firearm F and light 10. Referring toFIG. 10 , aseal 62 is received by a recess in an upper surface of thebattery door 16. When thebattery door 16 is closed, theseal 62 sealingly engages a lower surface 64 (FIG. 8 ) of thehousing 12 surrounding thebattery compartment 50 to substantially prevent water and contaminants from entering thebattery compartment 50 through thebattery opening 54. As shown inFIG. 10 , theside walls 16 b-c of thebattery door 16 extend above theseal 62. As shown inFIG. 12 , theretainer 56 includes a mountingstrip 56 d extending longitudinally above thelower wall 16 a. A mountingplate 65 positioned above the mountingstrip 56 d mounts to thelower wall 16 a to sandwich the mountingstrip 56 d between the mountingplate 65 andlower wall 16 a. -
FIG. 11 shows thehousing 12 including aninner body 66 and anouter body 68. Theouter body 68 includes anopening 70 at its rear through which theinner body 66 may be inserted into a cavity of theouter body 68. Theinner body 66 is mounted to theouter body 68 with fasteners 72 a-b that are received by openings 74 a-b, respectively, in anupper surface 76 of theouter body 68 and threaded openings 78 a-b, respectively, in anupper surface 80 of theinner body 66. The fasteners 72 a-b are countersunk so that the fasteners 72 a-b do not extend above theupper surface 76. Thebattery door 16 is joined to the bottom 12 d of theouter body 68, as described in more detail above. - The
inner body 66 includes a rectangular shapedrecess 82 formed in itsupper surface 80. Therecess 82 is sized to receive alug support plate 84 in a manner that an upper surface of thelug support plate 84 is flush with theupper surface 76 of theouter body 68, as shown inFIG. 1 , when theinner body 66 is mounted to theouter body 68. Theplate 84 is received by an opening 85 (FIG. 4 ) in theupper surface 76 of theouter body 68. Theplate 84 is joined to theinner body 66 with fasteners 86 a-b (FIG. 12 ) that are received by threaded openings in posts 88 a-b extending upward from the lower surface of therecess 82. The fasteners 86 a-b are countersunk so that they do not extend above the upper surface of theplate 84. Anotherpost 90 extending upward from therecess 82 is received by a recess 92 (FIG. 12 ) formed in a lower surface of theplate 84. Thepost 90 is offset from a midpoint of therecess 82 along the accessory axis AA in such a manner that theplate 84 is only insertable in therecess 82 in a single orientation. Theplate 84 may be mounted to theinner body 66 after theinner body 66 is inserted into and mounted to theouter body 68. - The
plate 84 has four rows of threaded openings or lug receivers, one of which is identified as 94 inFIG. 11 . The rows are spaced apart longitudinally across the accessory axis AA, and there are twolug receivers 94 in each row. The surface at the bottom of therecess 82 includes openings, one of which is identified as 96, that are aligned with thelug receivers 94.FIG. 11 shows eight threaded set screws or lugs, one of which is identified as 98, that are configured to be received by theopenings 96 and threadingly engage thelug receivers 94 in theplate 84. For example,FIG. 13 shows four of thelugs 98 received by theopenings 96 and threadingly engaged with thelug receivers 94. Thelugs 98 may be advanced upward above the upper surface of theplate 84 to be received by the recess G in the bottom of the firearm rail R (FIG. 21 ) and prevent longitudinal movement of the light 10 along the rail axis RA during operation of the firearm F. -
FIG. 11 shows six of thelugs 98 having the same diameter, which is constant along the length of the lug. Two of thelugs 98 a-b have a threadedsection 100, which has a diameter the same as the rest of the lugs, and an unthreadedsection 102 extending upward from the threadedsection 100. The unthreadedsection 102 has a smaller diameter than the threadedsection 100. The threadedsection 100 engages thelug receiver 94 in theplate 84, while the unthreadedsection 102 extends above theplate 84 to be received in the recess G of a firearm F. Thelugs 98 a-b may be used side-by-side in two of thelug receivers 94 with a firearm F having a recess G with a lesser width than the diameter of the larger lugs 98. For example, GLOCK branded firearms may have a rail R with a recess G that has a lesser width than the recess in the rail of other types of firearms. The unthreadedsection 102 of thelugs 98 a-b may have a diameter adapted to fit within this lesser width recess G. The forward most row of lug receivers 94 (i.e., lugreceivers 94 a-b) may further be spaced from theswitches 14 a-b a distance that positions theswitches 14 a-b adjacent the trigger guard TG of a GLOCK branded firearm when thelugs 98 a-b engage thelug receivers 94 a-b. Thelugs 98 a-b may further be used in any of the rows oflug receivers 94 depending on the width and location of a recess G that is desired to be engaged by thelugs 98 a-b. The remainder of thelugs 98, which have a constant diameter, may be suited for use with a firearm F having a rail R that is a Picatinny rail or MIL-STD-1913 rail. Thus, the diameter of theselugs 98 may be suited for being received by the recess G of a Picatinny rail. Any number of thelugs 98 may be used when mounting the light 10 on a rail R. However, in typical installations, only two oflugs lugs 98 are placed side-by-side within one of the rows oflug receivers 94. For example, two of thelugs 98 are advanced upward above the upper surface of theplate 84 in a single row oflug receivers 94 that, when aligned with the recess G of a firearm rail R, positions theswitches 14 a-b a desired distance from the trigger guard TG of the firearm F (e.g., a distance at which they may be conveniently actuated by a user as shown inFIG. 22 ). -
FIG. 14 shows two of thelugs 98 in cross-section view with a portion of thelugs 98 positioned above theplate 84, andFIG. 15 shows thelugs 98 a-b in cross-section view with the unthreadedsection 102 positioned above theplate 84 and the threadedsection 100 engaging the threaded opening of thelug receivers 94. - The
lug receivers 94 that are not in use receive plugs, one of which is identified as 104 inFIG. 23 . Theplugs 104 sealingly engage any of thelug receivers 94 that are not in use in order to prevent water and other contaminants from entering the inside of theinner body 66.FIG. 23 shows theplate 84 with sixplugs 104 received by three rows of thelug receivers 94 and twolugs 98 engaging thelug receivers 94 in one of the rows.FIG. 24 shows the configuration of theplugs 104 in more detail. Theplugs 104 have a cylindricallower portion 104 a and ahead 104 b extending upward from thelower portion 104 a and having a larger diameter than thelower portion 104 a. Referring toFIG. 12 , agasket 106 with substantially the same shape as theplate 84 is positioned between theplate 84 and theinner body 66 to further seal the inside of theinner body 66 against water and other contaminants. - Referring to
FIG. 9 , thelug receivers 94 are accessible through thebattery opening 54 when thebattery door 16 is in the open position and thebattery 52 is removed.FIG. 9 shows alug 98 engaging each of thelug receivers 94.FIG. 13 shows thelugs 98 having aninternal socket 108 that is operable to receive a tool for rotating thelugs 98 and advancing them upward or downward in thelug receivers 94. Theinternal recess 98 is shown as having a hexagonal cross-section, which is suited for receiving a hex key wrench. - Referring to
FIGS. 1 and 14 , themount 22 includes first and second rail engagement arms 110 a-b at a top 12 c of thehousing 12 extending upward from theupper surface 76. The first and second rail engagement arms 110 a-b are spaced from each other to define a gap for receiving the rail R therein. The first and second rail engagement arms 110 a-b are shaped and arranged to engage respective ridges R′ on the opposite sides of the rail R when the rail is received in the gap for retaining the light 10 on the rail. More specifically, the arms 110 a-b have inward facing rail engagement surfaces 112 a-b shaped to conformally engage the ridges R′ on the opposite sides of the rails R. In the illustrated embodiment, the rail engagement surfaces 112 a-b are concave. The first and second rail engagement arms 110 a-b are formed as one piece with theouter body 68 of thehousing 12 and extend upward from the housing. Thelug receivers 94 are positioned adjacent and between the first and second rail engagement arms 110 a-b. To mount the light 10 on a handgun F (FIG. 21 ), the rail engagement arms 110 a-b are positioned in front of the rail R, the rail R is inserted in the gap between the rail engagement arms 110 a-b, and the light 10 is slid on the rail R toward the trigger guard TG. Thebattery door 16 is opened, and lugs 98 are threaded upward throughadjacent lug receivers 94 that are aligned with the recess G of the rail R. Thelugs 98 are advanced upward until they are received by the recess G and prevent longitudinal movement of the light 10 on the rail R. The fit of the rail engagement surfaces 112 a-b against the ridges R′ of the rail R locates the light 10 vertically on the handgun F, and thelugs 98 locate the light longitudinally on the handgun F. The lugs 98 are configured to engage the recess G of the rail R to limit movement of the light 10 along the length of the rail. For example, when the handgun F is fired, recoil of the handgun may tend to move the rail R rearward with respect to the light 10. Thelugs 98 assist in preventing the light from migrating forward on the rail R in response to recoil of the handgun F.FIG. 22A shows alug 98 positioned within the recess G of an accessory rail R for preventing movement of the light 10 longitudinally on the rail R. - An electrical system of the light 10 will now be described with reference to
FIGS. 16-18 . The electrical system includes circuitry placing theprimary light 18 and path light 20 in electrical communication with thebattery 52. The circuitry includes a first electrical contact 114 (FIG. 17 ) located at one end of thebattery compartment 50 for contacting a positive terminal of thebattery 52, and a secondelectrical contact 116 located at an opposite end of the battery compartment for contacting a negative terminal of the battery, thus placing the battery in electrical communication with the circuitry. The circuitry includes acircuit board structure 118 mounted to arear wall 66 a (FIG. 18 ) of theinner body 66 placingswitch assemblies 14 a-b in electronic communication with the circuitry. The circuitry can complete the circuit between thecircuit board structure 118 and theprimary light 18 and path light 20 in any suitable way, such as an electrical lead (not shown) extending forward along thebattery compartment 50 from thecircuit board structure 118 to theprimary light 18 and path light 20. - As shown in
FIG. 18 , thecircuit board structure 118 includes a firstlongitudinal circuit board 118 a and a secondtransverse circuit board 118 b in electrical communication with each other. Thelongitudinal circuit board 118 a may be joined to thetransverse circuit board 118 b by tongue and groove connection as well as by brackets. Thelongitudinal circuit board 118 a extends generally parallel with the accessory axis AA, and thetransverse circuit board 118 b extends generally perpendicular to the accessory axis. Thetransverse circuit board 118 b is sized and shaped to have a press fit in arecess 120 in therear wall 66 a of theinner body 66. Theelectrical contact 116 is in contact with thecircuit board 118 b through anopening 122 in therear wall 66 a. Thelongitudinal circuit board 118 a is centrally located between the sides of theinner body 66 and extends along the accessory axis AA. Two electronic switches 124 a-b are provided on opposite sides of thelongitudinal circuit board 118 a and are in electrical communication with the longitudinal circuit board and thus the circuitry. The electronic switches 124 a-b face laterally with respect to the accessory axis AA. The electronic switches 124 a-b include pressure surfaces, one of which is shown as 124 a′, responsive to pressing thereon for actuation of the electronic switches. As shown inFIGS. 16 and 18 , agasket 126 is sized and shaped to conformally fit around thecircuit board structure 118 to isolate the circuitry from ingress of water. Thegasket 126 sealingly engages between therear wall 66 a and a tail cap 128 (FIG. 16 ) that is attached to theinner body 66 with fasteners, one of which is identified as 130. Thetail cap 128 includes amain body 128 a that fits around thecircuit board structure 118 and rear end of theinner body 66, and twotabs 128 b (only one being shown) extending forward from either side of themain body 128 a. Anopening 132 in thetab 128 b aligns with a threadedopening 134 in the side of theinner body 66. Thefastener 130 is received by theopening 132 and engages the threadedopening 134 to secure thetail cap 128 to theinner body 66. Thetail cap 128 is further the portion of thehousing 12 that includes the keeper 60 (FIG. 7 ) that engages thelatch 58 of thebattery door 16. - The
tail cap 128 supports theswitches 14 a-b configured to actuate the respective electronic switches 124 a-b. Theswitches 14 a-b are engageable by a user and movable with respect to the respective electronic switches 124 a-b for actuating the electronic switches. As shown inFIGS. 16 and 17 , theswitches 14 a-b include paddles 136 a-b (broadly, “push members”) having proximal ends pivotally connected to thetail cap 128 by rods 138 a-b. The rods 138 a-b extend through aligned openings in thetabs 128 b of thetail cap 128 and in the paddles 136 a-b. The paddles 136 a-b include push surfaces 136 a-b′ engageable by a hand or finger of the user (e.g., trigger finger). In the illustrated embodiment, the push surfaces 136 a-b′ have a protruding ribbed pattern to provide the user with tactile indication that their finger is on the push surface. The paddles 136 a-b have inner surfaces 136 a-b″ opposite the push surfaces 136 a-b′ facing inward toward the accessory axis AA. The paddles 136 a-b are pivotable inward about the rods 138 a-b toward the accessory axis AA responsive to pushing force on the push surfaces 136 a-b′. - Each
switch 14 a-b includes a compression spring 140 a-b and a pin 142 a-b (broadly “finger”). As shown inFIG. 17 , the pins 142 a-b extend through the springs 140 a-b, and the pin and spring assemblies are received in recesses 144 a-b in opposite sides of thetail cap 128. O-ring seals 146 a-b are positioned in the recesses 144 a-b to seal the openings in thetail cap 128 through which the pins 142 a-b extend. The pins 142 a-b are elongate and have lengths along their longitudinal axes greater than their widths transverse to the longitudinal axes. The longitudinal axis of each pin 142 a-b is generally perpendicular to the push surface 136 a-b′ of the corresponding paddle 136 a-b and intersects thepressure surface 124 a′ of the respective electronic switch 124 a-b. The inner surfaces 136 a-b″ of the paddles 136 a-b each include a recess 148 (one of which is identified inFIG. 16 ) (broadly, “pin engagement portion”) positioned to receive an end of the respective pins 142 a-b and springs 140 a-b. The springs 140 a-b have inner ends that engage thetail cap 128 and outer ends that engage the inner surfaces 136 a-b″ of the paddles 136 a-b to bias the paddles 136 a-b and pins 142 a-b away from the electronic switches 124 a-b. The arrangement is such that the pins 142 a-b act as fingers extending inward from the inner surfaces 136 a-b″ of the paddles 136 a-b. When a paddle 136 a-b is pivoted inward its respective pin 142 a-b moves linearly as the respective spring 140 a-b is compressed, and the respective pin 142 a-b presses the respective electronic switch 124 a-b, thus actuating the electronic switch. Accordingly, the paddle push surface 136 a-b′ is pushable in the same direction in which the tip of the pin 142 a-b moves (in the direction of the longitudinal axis of the pin) to actuate the electronic switch 124 a-b. When the user releases the paddle 136 a-b, the spring 140 a-b pushes the pin 142 a-b and paddle 136 a-b outward to their non-actuated positions. Actuation of theswitches 14 a-b can turn theprimary light 18 on or off, or otherwise change operation of the light as described in more detail below. - Switch assemblies having other configurations can be used without departing from the scope of the present invention. For example, although the pins 142 a-b are illustrated as being separate from the paddles 136 a-b, the pins could be formed as one piece with the paddles. Moreover, other types of actuators and fingers having other configurations can be used. In some embodiments, the fingers can be omitted.
- Referring to
FIG. 17 , theminus button 46 on the side of thehousing 12, includes acover 150 mounted within an opening of theouter body 68 of thehousing 12. Aplate 152 is positioned behind thecover 150. Aseal 154 behind theplate 152 sealingly engages an opening in theinner body 66 of thehousing 12. Behind theseal 154 is aPCB 156 with a pressure switch that is configured to be actuated when a user presses on thecover 150. ThePCB 156 is in electrical communication with thecircuit board structure 118 andprimary light 18. Theplus button 48 includes a similar configuration as theminus button 46, and thus is not described in detail herein. -
FIGS. 19 and 20 show theprimary light 18 and itsPCB 36 mounted within anopening 158 in a front wall of theinner body 66. The path light 20 and itsPCB 42 are also mounted within theopening 158. Aring 160 protruding outward from the front wall defines theopening 158. ThePCB 36 is oriented transverse to the accessory axis AA extending across the width of theinner body 66, and thePCB 42 is oriented transverse to thePCB 36. ThePCB 42 also extends across the width of theinner body 66 and extends along the accessory axis AA. ThePCB 42 extends forward from thePCB 36, and a rear edge of thePCB 42 may be connected to a lower edge of thePCB 36. ThePCBs circuit board structure 118. - As shown in
FIGS. 17 and 19 , agasket 162 is positioned adjacent the front wall of theinner body 66 surrounding thering 160. Thegasket 162 seals between theinner body 66 and abezel 164. Thebezel 164 may be press fit to theinner body 66 around thering 160 or joined to theinner body 66 in any other suitable manner. Areflector 166 is positioned within thering 160 andbezel 164. Thereflector 166 has adistal opening 166 a that is approximately the same size as theprimary light 18 and aproximal opening 166 b. Theprimary light 18 extends through thedistal opening 166 a. Thereflector 166 has an interiorreflective surface 166 c that is configured to reflect light from theprimary light 18 in the first direction 32 (FIG. 1 ). Thefront lens 38 has adistal extension 38 a that fits within anopening 164 a of thebezel 164. Thefront lens 38 may be joined to thebezel 164 with a snap fit or any other suitable manner to cover theopening 164 a of thebezel 164 and opening 158 of theinner body 66. Thefront lens 38 is transparent to allow light emitted from theprimary light 18 to illuminate objects in front of the light 10. As shown inFIG. 12 , thebottom lens 44 fits within anopening 164 b in thebezel 164 that is positioned below the path light 20. Thebottom lens 44 may be joined to thebezel 164 with a snap fit or any other suitable manner. Thebottom lens 44 is transparent to allow light emitted from the path light 20 to illuminate objects below the light 10. Thebottom lens 44 is positioned above anopening 168 in the bottom of theouter body 68. The shape of thebottom lens 44 and configuration of thebezel 164 andouter body 68 direct light emitted from the path light 20 in the second direction 34 (FIG. 1 ). - Referring to
FIG. 25 , a control system of the light 10 is described in more detail. The control system includes acontroller 200 that is electrically connected to atimer 202, auser interface 204, astorage medium 206, anaccelerometer 208, theprimary light 18 and path light 20, and thebattery 52. Thecontroller 200,timer 202,storage medium 206, andaccelerometer 208 may be mounted on any of thePCBs controller 200 may be a microcontroller with thetimer 202 andstorage medium 206 incorporated into the microcontroller. Theuser interface 204 includes the electronic switches 124 a-b that control actuation of theprimary light 18, as described above, and theminus button 46 andplus button 48 that control the brightness of theprimary light 18. Thestorage medium 206 may be any type of storage medium configured to store instructions that are read and executed by thecontroller 200 for operating the light 10. Thestorage medium 206 may include non-volatile memory that retains mode settings of the light 10 upon a loss of power or removal of thebattery 52. Theaccelerometer 208 may sense when the light 10 is moving to cause thecontroller 200 to turn on the path light 20, as described in more detail below. While anaccelerometer 208 is shown, any type of motion sensor may be used to cause the path light 20 to turn on when the motion sensor senses that thehousing 12 is moving. Thebattery 52 is electrically coupled to thecontroller 200 for powering thecontroller 200 andlights controller 200 is configured to activate the path light 20 for an illumination time period (e.g., 15 seconds) when theaccelerometer 208 senses that thehousing 12 is moving. If theaccelerometer 208 senses continued movement while the path light 20 is on, the illumination time period is reset. In this manner, the path light 20 once on, does not turn off unless no motion is sensed during the entire illumination time period. At the end of the illumination time period, when no continued motion is sensed during the time period, thecontroller 200 causes the path light 20 to turn off. Thecontroller 200 may use thetimer 202 to count the illumination time period. Thecontroller 200 may also utilize thetimer 202 to turn off theprimary light 18 when it has been on for a predetermined amount of time. - The
controller 200 may be programmed or otherwise read and execute instructions on thestorage medium 206 to operate the light 10 in accordance with the following description. - When the
primary light 18 is off, a short tap of either switch 14 a or 14 b (e.g., a press and release within one second), turns on theprimary light 18. The light 10 is either set at its factory default mode or its last saved mode (if available). The mode may include the brightness setting and also whether the light is on continuously or in strobe mode, as described below. Theprimary light 18 remains constantly on when theswitch 14 a-b is released. - When the
primary light 18 is off, a long hold of either switch 14 a or 14 b (e.g., a press and release after one second) turns theprimary light 18 on for as long as theswitch switch 14 a-b is released, theprimary light 18 turns off. The light 10 is either set at its factory default mode or its last saved mode (if available). The current mode of the light 10 will be saved when it is switched off. After 45 seconds of a long hold, thecontroller 200 will turn theprimary light 18 off. - When the
primary light 18 is off, pressing theminus button 46 or theplus button 48 individually or together for less than three seconds does not change operation of the light 10. Pressing bothbuttons accelerometer 208 for the path light 20. - When the
primary light 18 is on, a short tap of either switch 14 a or 14 b (e.g., a press and release within one second), turns off theprimary light 18 when theswitch 14 a-b is released. Theprimary light 18 remains on while the switch is pressed. The current mode of the light 10 will be saved when it is turned off. - When the
primary light 18 is on, a long hold of either switch 14 a or 14 b (e.g., a press and release after one second) turns theprimary light 18 off when the switch is released. Theprimary light 18 remains on while the switch is pressed. The current mode of the light 10 will be saved when it is turned off. - When the
primary light 18 is on, a short tap (e.g., a press and release within one second) of theplus button 48 changes the brightness setting of theprimary light 18 up to the next discrete interval brightness setting as set forth in Table A below (i.e., thesettings 1, 2, 3, 4, or 5). If the brightness setting is already at 5, the mode will remain unchanged. For example, if the current brightness setting is at mode 3.6 (340 lumens), a short tap of theplus button 48 will change the setting to mode 4.0 (500 lumens). If the current brightness setting is at mode 1.0 (5 lumens), a short tap of theplus button 48 will change the setting to mode 2.0 (100 lumens). - When the
primary light 18 is on, a short tap (e.g., a press and release within one second) of theminus button 46 changes the brightness setting of theprimary light 18 down to the next discrete interval brightness setting as set forth in Table A below. If the setting is already atmode 1, it will remain unchanged. For example, if the current brightness setting is at mode 3.6 (340 lumens), a short tap of theminus button 46 will change the setting to mode 3.0 (250 lumens). If the current brightness setting is at mode 2.0 (100 lumens), a short tap of theminus button 46 will change the setting to mode 1.0 (5 lumens). - When the
primary light 18 is on, a long hold of the plus button 48 (e.g., a press and release after one second) causes the brightness setting to incrementally rise through the settings set forth in Table A below as long as theplus button 48 is pressed. For example, if the current setting is mode 1.0, the brightness will progress from 1.0 to 1.1, 1.2, 1.3, etc. for as long as the button is pressed. When the button is released, theprimary light 18 will remain on the lumen setting that is set at the time the button is released. If setting 5.0 is reached, theprimary light 18 will blink three times, indicating to the operator that the light will not increase lumen settings any further. At that point, the light will remain at brightness setting 5.0. - When the
primary light 18 is on, a long hold of the minus button 46 (e.g., a press and release after one second) causes the brightness setting to incrementally descend through the settings set forth in Table A below as long as theminus button 46 is pressed. For example, if the current setting is mode 5.0, the brightness will progress from 5.0 to 4.9, 4.8, 4.7, etc. for as long as the button is pressed. When the button is released, theprimary light 18 will remain on the lumen setting that is set at the time the button is released. If setting 1.0 is reached, theprimary light 18 will blink three times, indicating to the operator that the light will not decrease lumen settings any further. At that point, the light will remain at brightness setting 1.0. - When the
primary light 18 is on, pressing both of the minus andplus buttons primary light 18 is set to be on continuously, pressing both buttons may activate a strobe setting in which the light flashes at predetermined intervals. - If the
primary light 18 has continued to operate at any single mode for five minutes without any new command input, the light will start to blink (e.g., 0.5 seconds off then 0.5 seconds on) for three times in a three second time period. After blinking, theprimary light 18 shall timeout and auto power off. A short tap of either switch 14 a-b during the three second blinking mode will cancel and reset the timeout, and theprimary light 18 will continue to operate at its current mode for another five minute countdown. - If the path
light accelerometer 208 is in the on state (i.e., it senses acceleration), the path light 20 will activate instantly upon the acceleration being sensed. Once the path light is activated, it will continue to run for fifteen seconds. After fifteen seconds the path light will turn off. Any acceleration detected during the fifteen second countdown window will automatically reset the countdown timer. There is no limit on the number of cycles the countdown timer can be reset. - If the path
light accelerometer 208 is in the off state (i.e., no acceleration is sensed), the path light 20 will remain off until the accelerometer state is changed. - The path light 20 remains off and turns on whenever movement is detected. The accelerometer may turn on when acceleration between 0-16G is sensed. The accelerometer may be a high efficiency power consumption model. The path light 20 may optionally be configured to turn on manually.
- As set forth in Table A below, there are five discrete brightness settings as follows: setting 1.0 at 5 lumens, setting 2.0 at 100 lumens, setting 3.0 at 250 lumens, setting 4.0 at 500 lumens, and setting 5.0 at 1000 lumens. There are nine “infinite” brightness settings between each of the discrete brightness settings, which may be reached by holding either the plus or minus button down for more than one second as described above.
