This disclosure relates to lighting devices and, in particular, to lighted headgear and accessories therefor.
Often an individual desires a light source focused to illuminate an area while performing a task, or a light source directed in a general outward direction for visibility. Holding a typical flashlight is an option, but such lighting devices are often cumbersome and may detract from the task being completed because the flashlight must be held with one hand leaving only the other hand free for performing the task. As a result, hands-free lighting is often desired because the individual desiring illumination does not need to hold the light source. Hands-free lighting that include light sources mounted to headgear or eyeglasses are known.
Lighted headgear may include illumination sources mounted to hats. The light source can be oriented to direct light outwardly in such a manner so that the wearer can be seen by others or oriented downward and forward to illuminate an area in the wearer's field of view. Often, the light source is one or more LEDs. Such LED lighted headgear, which may include LEDs mounted to a typical baseball-style hap or beanie-style cap, are convenient for hands-free lighting in a number of recreational activities, such as camping, hunting, fishing, jogging, or the like.
Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments may take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures is combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.
In general, the lighted headgear and light module accessories described herein include self-contained light modules. As used herein, self-contained light modules include one or more illumination sources and one or more internal power sources to energize the illumination sources. The one or more illumination sources include, for example, one or more light-emitting diodes (LEDs). The power sources may be batteries such as rechargeable batteries (e.g., lithium-ion batteries). The lighted headgear and light module accessories include battery charging interfaces for recharging rechargeable batteries. As used herein, a battery charging interface may be a fixed electrical interface such as a USB port that is electrically coupled to a rechargeable battery. In this way, a user may connect a power cable to the battery charging interface to recharge the rechargeable battery. The battery charging interfaces are covered when the self-contained light modules are assembled so as to protect internal components of the self-contained light modules from moisture and debris. The self-contained light modules may be removed from an article of clothing and disassembled to permit access to the battery charging interfaces for recharging the light modules.
The light module accessories described herein may be mounted to headgear or other articles of clothing. The headgear may include, for example, a baseball-style hat, a beanie-style cap, or other suitable headgear such as visors, helmets, caps, hats, headbands, sweatband, hoods, clothing, or the like. While the following description and illustrations may describe a specific power assembly and illumination source with a specific headgear or accessory, the various components described herein may be included in any of the embodiments.

The brim portion 14 has an upper major surface 30 and a lower major surface 32. As used herein, the upper major surface 30 faces generally upwardly when the lighted hat 10 is worn by a user, and the lower major surface 32 faces generally downwardly when the lighted hat 10 is worn by a user. The upper major surface 30 may be an upper surface of an upper covering, and the lower major surface 32 may be lower surface of a lower covering. For example, the upper major surface 30 and the lower major surface 32 may be surfaces of fabric coverings or other suitable material.
The brim portion 14 can further include a brim insert 40 that extends between the upper major surface 30 and the lower major surface 32. The brim portion 14 includes perimeter edge portions, such as side edge portions 42 and a front edge portion 44 that extends between the side edge portions 42. The brim portion 14, and more particularly, the lower major surface 32, has a generally fore-and-aft central axis 46 that extends in a forward direction between the side edges 42 and toward the front edge 44. The upper and lower major surfaces 30, 32 and the brim insert 40 may be joined together, such as by stitching, adhesive, or the like.
The lighted hat 10 includes a light module 50 and a mount 52 for securing the light module 50 to the lighted hat 10. The mount 52 is fixedly secured at the lower major surface 32 of the brim portion 14, which may be a generally arcuate downwardly-facing surface of the brim portion 14. The mount 52 has a plate body 52A that includes an upper plate wall 53. Prior to the mount 52 being secured to the brim portion 14, the upper plate wall 53 may be generally planar between opposite side edges 61 of the mount 52. The mount 52 may be formed of a resilient elastomeric material such that when the mount 52 is secured to the brim portion 14, the upper plate wall 53 generally conforms to the arcuate downwardly-facing surface 32 of the brim portion 14. For example, with the mount 52 secured to the brim portion 14, the side edges 61 of the mount 52 are lower than a central portion 63 of the mount 52 to provide a flush fit between the mount 52 and the arcuate brim portion 14. The mount 52 may be secured to the lower major surface 32, for example, via adhesive, heat sealing, fasteners, etc. As discussed, the lower major surface 32 may be a lower surface fabric covering. As described below, the mount 52 retains the light module 50 as the light module slides along a longitudinal axis between a first longitudinal position within the mount and a second longitudinal position offset from the first axial position.
As shown in
With the light module 50 slid out of engagement with the mount 52, a user may access a battery charging interface 108 of the light module 50 through an access port or opening 156 in a housing cover 150 to recharge the power source 54 of the light module 50. When the light module 50 is installed with the mount 52, the access opening 156 is covered by the mount 52 such that the battery charging interface 108 is inaccessible and is protected by the mount 52. In one approach, the light module 50 forms a fluid-tight or substantially fluid-tight seal with the mount 52 when installed with the mount 52 (e.g., sufficient to comply with Ingress Protection (IP) rating of IP 67). For example, the inter-engagement between the flange portions 160 of the light module 50 and the tracks 55 of the mount 52 may form a watertight seal.

As shown in
As discussed in greater detail below, the lower housing 60 houses a power source 54, a light source 90, and other components discussed herein within an interior 64 of the lower housing 60.
The housing cover 150 extends over the components contained in the lower housing 60. The housing cover 150 has a generally arcuate upper surface 151 that curves from one side edge to the opposite side edge. The curvature of the arcuate upper surface 151 may have a curvature that generally corresponds to a curvature of a brim portion 14 of a hat 10. The housing cover 150 may be formed of a material such as plastic that is more rigid than the resilient elastomeric material of the mount 52. In one form, the curvature of the mount 52 secured to the brim portion 14 is slightly less than that of the housing cover 150. In this way, when the light module 50 is removably secured to the mount 52, the housing cover 150 causes the mount 52 to generally conform to the curvature of the housing cover 150 (see e.g.,
The housing cover 150 is secured to the lower housing 60 to form the housing assembly 58. For example, one or more fasteners 152 may be used to secure the housing cover 150 to the lower housing 60 at fastener holes 152A, 152B in the housing cover 150 and lower housing 60, respectively. In another approach, the housing cover 150 may be integrally formed with at least a portion of the lower housing 60.
The housing cover 150 may have a lateral dimension (e.g., in the Y direction) that is greater than a lateral dimension of the lower housing 60. In this way, the housing cover 150 forms one or more overhangs or flange portions 160 that extend laterally outwardly from the lower housing 60. As shown in
As discussed, the light module 50 includes one or more power sources 54 for energizing a light source 90. In the illustrated and preferred form, the power source 54 is a rechargeable (e.g., lithium-ion) battery. In other approaches, the power source 54 may be non-rechargeable, replaceable batteries such as cylindrical batteries, coin cell batteries, or the like.
The light module 50 further includes a light source 90 mounted at least partially within the housing interior 64. The light source 90 provides illumination outwardly from the housing assembly 58; for example, through the forward opening 80. When the light module 50 is installed with the mount 52, the forward opening 80 of the lower housing 60 is below the mount 52 (e.g., below central portion 63 of the mount 52) such that the light source 90 is oriented forwardly and downwardly of the mount 52. As illustrated, the light source 90 includes a single LED. A cover or lens 92 may extend across the LED light source 90.
The light module 50 further includes a heat sink member 94. The heat sink member 94 is formed of, or includes, conductive material. More particularly, the heat sink member 94 is formed of a material with high thermal conductivity, such as an aluminum alloy. As such, the heat sink member 94 may have a thermal conductivity value of between about 120 W/mK to about 240 W/mK to conduct heat away from the light source 90 during operation of the light module 50. The heat conduction by the heat sink member 94 reduces the risk of damaging components of the light module 50 through overheating. As shown, the heat sink member 94 has a generally rectangular body. Although depicted as having a single heat sink member 94, the light module 50 may be provided with two or more heat sink members.
The light module 50 also includes a switch device 100. The switch device 100 is electrically coupled to the light source 90 and the power source 54 for selectively energizing the light source 90. The switch device 100 includes, for example, a circuit board 102 and a battery charging interface 108 in the housing interior 64, and an actuator 110, which may include a push-button actuator that extends from the housing interior 64 to the exterior of the housing 50 to be accessed by a user. The circuit board 102, which may be a printed circuit board (PCB) that includes electrical circuitry 106, is electrically coupled to the light source 90.
The battery charging interface 108 receives charging power for charging the power source 54. The battery charging interface 108 may include, for example, a universal serial bus (USB) interface that receives power from an external source through a USB charging cable. The USB interface may be a USB-A, USB-B, USB-C, USB, micro USB, or mini USB interface. Other suitable battery charging interfaces 108 such as Firewire, Lightning connector, or Ethernet interfaces may be used. The battery charging interface 108 is aligned with the access opening 156 of the housing cover 150 such that a power supply can be inserted through the access opening 156 into the housing interior 64 to engage the battery charging interface 108.
In the assembled configuration, the heat sink member 94 is coupled to the circuit board 102, and the light source 90 is secured to a heat sink member 94. More particularly, the heat sink member 94 is disposed between the light source 90 and the circuit board 102 such that the light source 90 is separated from the circuit board 102 by the heat sink member 94. As shown, the heat sink member 94 may be installed to be fixed in an inclined orientation relative to the circuit board 102. The inclination of the heat sink member 94 including the light source 90 fixed thereto generally corresponds to that of the forward inclined wall portion 70. In this way, the heat sink member 94 is oriented to extend generally parallel to the forward wall portion 70.
The light module 50 further includes a reflector 130. The reflector 130 may be a discrete reflector that is mounted to the lower housing 60 generally in the housing interior 64. More particularly, the reflector 130 is mounted at the forward opening 80 of the lower housing 60. The reflector 130 includes a rearward opening 132 (
As discussed, the mount 52 includes one or more tracks 55 having a channel 55A formed therein for receiving and guiding the flanges 160 of the housing cover 150 to guide translation of the light module 50. The channel 55A can have a slot configuration. More particularly, and with reference to
When the light module 50 is removably secured to the mount 52, the flanges 160 are received in the track channels 55A, and the wall portions 53, 171, 172 cooperate to inhibit movement of the light module 50. For example, the depending wall portions 171 restrict lateral movement of the light module 50, and the support wall portions 172 support the weight of the light module 50 and keep the light module 50 from falling from the lighted hat 10 when worn.
Referring to
During installation of the light module 50, the light module 50 is slid along edge portions of the track 55 of the mount 52 until a forward portion of the light module 50 (e.g., forward flange 160B) abuts an internal surface of the forward edge wall portion 174. As discussed, the mount 52 is formed of a resilient elastomeric material and has a generally planar upper plate wall 53. Sliding of the light module 50 along the track 55 causes the flanges 160 of the light module 50 to bend the upper plate wall 53 and conform the mount 52 to the curvature of the housing cover 150. Upon installation, this tight engagement between the housing cover 150 of the light module 50 and the track 55 of the mount 52 secures the light module 50 to the lighted hat 10.
As discussed, the light module 50 and the mount 52 cooperate to protect the battery charging interface 108 and other internal components of the light module 50 from moisture or debris when the light module 50 is installed with the mount 52. For example, the upper plate wall 53 of the mount 52 extends over and blocks access to the access opening 156 of the light module 50 when the light module 50 is installed with the mount 52. Furthermore, as discussed above, the housing cover 150 of the light module 50 cooperates with the resilient elastomeric mount 52 to be in tight engagement therewith so as to form a fluid-tight or substantially fluid-tight seal around a perimeter of the light module 50 when the flanges 160 of the light module 50 are received in the track channels 55A of the mount 52. As also discussed, the light module 50 may subsequently be removed from the mount 52 (e.g., slid in an opposite linear direction) to recharge the power source 54.

The light module 200 includes a light module body 202 and a mount or attachment member such as a clip 204. The clip 204 includes a lower arm 212 that is releasably secured to the light module body 202, as discussed in greater detail below. The clip 204 also includes a resilient upper spring arm 210 that can be flexed about a hinge portion 214 of the clip 204, which may be an arcuate hinge portion that interconnects the arms 210 and 212. As shown in
As shown in
With the lower arm 212 releasably secured to the light module body 202, the upper spring arm 210 can be resiliently shifted away from the lower arm 212 about the arcuate hinge portion 214 to an open configuration such that the upper spring arm 210 is spaced from the module body 202 to allow the brim portion 14 of the hat 10′ to fit therebetween to permit a user to slide the clip 204 across the upper major surface 30 of the brim portion 14 of the hat 10′ (e.g., at the front edge 44). Upon release of the upper spring arm 210, the hinge portion 214 biases the upper spring arm 210 back toward the light module body 202. In this way, when the light module 200 is installed on a hat 10′, the upper and lower arms 210, 212 of the clip 204 cooperate to clamp or pinch the brim portion 14 therebetween to releasably secure the light module 200 on the brim portion 14. A user may adjust the position of the light module 200 on the brim portion 14 by sliding the light module 200 backward (toward the users head) until the front edge 44 of the brim portion 14 abuts the hinge portion 214. In the installed configuration with the light module 200 releasably secured to the hat 10′, the lower arm 212 maintains the light module body 202 tightly engaged against the lower major surface 32 to provide illumination generally forwardly and downwardly from the hat 10′.
Referring to
The light module body 202 has many of the same features as the light module 50 of
The light module body 202 further includes a housing cover 230 as mentioned that is secured to the lower housing 60, for example, with one or more fasteners 232. The housing cover 230 includes a clip opening 240 for receiving the generally rigid lower arm 212 of the clip 204 therethrough. The clip opening 240 includes a lead-in portion a ledge 241 and guide walls 241′ for guiding initial insertion of the clip 204 through the clip opening 240. For example, and referring to
Also when the lower arm 212 is fully inserted, the lower arm 212 may cooperate with the housing cover 230 to form a releasable lock or detent 253 that resists relative axial movement therebetween. For example, the lower arm 212 includes indents 245 formed in opposite side portions 247 of the lower arm 212. The housing cover 230 (as shown through the partial cross-section indicated at “A” in
In this way, the housing cover 230 forms a guide slot 234 having a length (e.g., in the X direction) between the stop 238 and the clip opening 240, and a height (e.g., in the Z direction) between the lower support surfaces 236 and an upper wall portion 237 of the housing cover 230. The height and length of the guide slot 234 are slightly larger than the thickness and length, respectively, of the lower arm 212 such that the lower arm 212 is snuggly received in the light module body 202 when the clip 204 is removably secured or attached thereto.
The housing cover 230 further includes an access port or opening 242 that is generally aligned with the battery charging interface 108 in the Z direction for permitting access to the battery charging interface 108. For example, the access opening may be aligned with the battery charging interface along axis 243 that may be orthogonal to and/or intersect longitudinal axis 235.
When the clip 204 is assembled with the light module body 202, the lower arm 212 extends across the access opening 242 between the housing cover 230 and the battery charging interface 108 to cover and block access to the battery charging interface 108. In this way, when the light module 200 is assembled, liquids and debris are blocked from passing through the access opening 242 and into the light module body 202 to avoid fouling the battery charging interface 108 in the lower housing 60.

The light module 320 includes a housing 360 that may include an outer or externally-facing housing portion 362 and an inner or internally-facing housing portion 364. The outer housing portion 362 and inner housing portion 364 may be formed of similar or dissimilar materials. The inner housing portion 364 may be secured to the outer housing portion 362, for example, by one or more fasteners 366 (see
The outer housing portion 362 includes a peripheral wall portion 370 that extends about the interior 372 of the outer housing portion 362. A forward flange 332 extends outwardly away from the peripheral wall portion 370. The inner housing portion 364 extends across the interior 372 of the outer housing portion 362 and outwardly beyond the peripheral wall portion 370. In this way, a rear flange 374 of the inner housing portion 364 cooperates with the forward flange 332 and the peripheral wall portion 370 to form a groove 380 for receiving a portion of the mount 322 (e.g., inner retention portion 352) therebetween to secure the light module 320 to the mount 322.
In one approach, the light module 320 forms a fluid-tight or substantially fluid-tight seal with the mount 322 when installed with the mount 322 (e.g., sufficient to comply with Ingress Protection (IP) rating of IP 67). For example, the interlock between the inner retention portion 352 of the mount 322 and the inner housing portion 364 and forward flange 332 of the light module 320 may form a watertight seal.
The mount 322 may be formed of a generally flexible material that is capable of flexing when a user presses the light module 320 in the direction indicated by arrow 330. Thus, to remove the light module 320 from the mount 322, a user can press the light module 320 in direction 330 to cause the mount 322 to flex and allow the rear flange 374 of the inner housing portion 364 to bypass the rear flange 374 to release the light module 320 from the mount 322.
A user may desire to detach the light module 320 the mount 322, for example, to recharge or replace a power source 54 of the light module 320. The light module 320 is provided with an opening 382 that is generally aligned with the battery charging interface 108. For example, the opening 382 may extend through the inner housing portion 364 of the housing 360 adjacent the battery charging interface 108. A port cover 340 extends over the opening 382 to protect the battery charging interface 108 and other internal components of the light module 320 from moisture or debris. When a user desires to charge the light module 320, the port cover 340 may be moved or removed to expose the battery charging interface 108.
To install or reinstall the light module 320, a user may work a portion of the mount 322 into the groove 380 of the light module 320. The user may continue to work other portions of the mount 322 into the groove 380 until the mount 322 is fully received in the groove 380 about the entire periphery of the light module 320. With the light module 320 removably installed on the mount 322, the forward flange 332 and the rear flange 374 of the light module 320 cooperate with the mount 322 to maintain the light module 320 on the lighted cap 300.

The headlamp 500 further includes a light module 550 that includes a housing 560. The housing 560 may include an outer or externally-facing housing portion 562 and an inner or internally-facing housing portion 564. The outer housing portion 562 and inner housing portion 564 may be formed of similar or dissimilar materials. The housing 560 houses many of the same features as the light module 50 of
The outer housing portion 562 includes a peripheral wall portion 570 that extends about the interior 572 of the outer housing portion 562. A flange 532 of the outer housing portion 562 extends outwardly away from the peripheral wall portion 570. The inner housing portion 564 extends across the interior 572 of the outer housing portion 562 and outwardly beyond the peripheral wall portion 570. In this way, the periphery of the inner housing portion 564, as indicated at 574, cooperates with the flange 532 and the peripheral wall portion 570 to form a groove 580 for receiving a rim portion 510 of the mounting portion 504 therebetween to secure the light module 550 to the mounting portion 504.
The mounting portion 504 is formed of a material that is more flexible than the inner housing portion 564 and that is capable of flexing when a user pulls the light module 550 away from the mounting portion 504. Thus, to remove the light module 550 from the mounting portion 504, a user can pull the light module away 550 from the mounting portion 504, causing the rim portion 510 to flex a sufficient amount out of the groove 580 to release the periphery 574 of the inner housing portion 564 and free the light module 550, as shown in
To install or reinstall the light module 550, a user may work a portion of the rim portion 510 of the mounting portion 504 into the groove 580 of the light module 550. The user may continue to work other portions of the rim portion 510 into the groove 580 until the rim portion 510 is fully received in the groove 580 about the entire periphery of the light module 550. With the light module 550 removably installed on the mounting portion 504, the flange 532 and the inner housing portion 564 of the light module 550 cooperate with the rim portion 510 to maintain the light module 550 on the headlamp 500.
