[0032]
[0033] As explained below, the adjustable, flexible, deployable lighting element 100, the LED array and the support panel 120 of the wearable lighting device 10 are configured to be (i) collapsed to a retracted position abutting the housing 200, and/or (ii) deployed to extend outward from the housing 200, whereby the position of lighting element 100 is adjustable to direct the light provided by the LED array 110. The wearable lighting device 10 is configured to be carried or stored in with the adjustable lighting element 100 in a retracted position or compact state S.sub.C (
Housing
[0034] As shown in
[0035] The arrangement of edge walls 230 includes a front portion 240, an opposing base portion 270, and side edge walls 250 extending there between. The front portion 240 includes a cavity 213 separating two front edge walls 242, where the cavity 213 is aligned with the frontal securement recess 261 and includes a front facing middle wall 244 and two recess walls 246 extending forward to the two front edge walls 242. The two front edge walls 242 being substantially in the same plane and the front facing middle wall 244 spaced back and substantially parallel to the two front edge walls 242. The two recess walls 246 can be substantially parallel to each other and substantially perpendicular to the two front edge walls 242 and the front facing middle wall 244. The two side edge walls 250 are curvilinear and include front rounded corners 252 as transition from each of the front edge walls 242, a curved transition 253 to a substantially flat portion 254 at least partially recessed from the flange portions 218, 219, 228, 229 of the first and second face walls 212, 214 and defining the securement recesses 260. As shown in
[0036] A charging port 340 can be positioned for access through a base receptacle 274 in the base edge wall 272. The housing 200 may include a cover 276 to cover the base receptacle 274 when not in use, providing additional protection to the enclosure. The charging port 340 may be recessed in the base receptacle 274 and the cover 276 may fit substantially within the base receptacle 274 to maintain a flush surface along the base edge wall 272, such that the wearable lighting device 10 can be positioned to stand alone on a flat surface. The wearable lighting device 10 is operable as a light and the lighting element 100 can be positioned whether attached to an item by the attachment means 290 or positioned on a surface standing on the base edge wall 272 or other surface.
[0037] The housing 200 may be formed from: (i) metal, such as aluminum or steel, (ii) a polymer material, such as plastic, (iii) a magnetic material, or (iv) a combination of the prior material. The housing 200 can be made from various materials (e.g., plastic, metal, etc.) and may be made using any suitable technique (e.g., injection molding, 3D printing, etc.). In certain embodiments, part of the housing 200 (e.g., the first body 210 and the second body 220) may be made from one material (e.g., metal), and another part of the housing 200 (e.g., cover 276) may be made from a second material (e.g., plastic). The housing 200 including the cover 276 and the button 332 are designed to protect the electronic package 300 from external solid, liquid, and/or gaseous matter, which in some embodiments allows the housing 200 and the device 10 to be substantially waterproof (e.g., the device 10 meets the ip67 or ip68 standards).
Lighting Element
[0038] The lighting element 100 includes a flexible LED array 110 and a coupling portion 140 configured to couple the lighting element 100 to the housing 200. The coupling portion 140 includes a pivot portion 142a and a pivot portion 142b that, when assembled to each other, form a structure that is analogous to an axle that is partly retained within a pair of apertures 144 defined in the front portion 203.
[0039] The flexible LED array 110 includes a light source 302 coupled to a flexible backing support member configured as a base strip 112. The flexible LED array 110 includes a central array region 130, two flexible and deformable lighting panels 120 extending outward therefrom, and opposing end portions 114. The coupling portion 140 is pivotably coupled to the housing 200 within the cavity 213. Each of the flexible panels 120 of the flexible LED array 110 are configured to bend, flex, and/or deform to be received into respective securement recesses 260 of the side edge walls 250.
[0040] In some embodiments, the flexible LED array 110 can be configured as an elongate member (where its length (or width) substantially exceeds its height, when viewed in a front plan view), such as strip or as a panel. In some embodiments, the flexible LED array 110 can include joints defined between the central array region 130 and said flexible panel 120. In such examples, the flexible LED array 110 can be configured to bend at the joints. The flexible LED array 110 is fixed to the coupling portion 140 at the central array region 130 of the base array 112 such that the light source 302 is facing outward from the housing 200. The coupling portion 140 includes a pivot portion 142a and a pivot portion 142b that, when assembled to each other, form a structure that is analogous to an axle that is partly retained within a pair of apertures 144 defined in the front portion 203.
[0041] The light source 302 may be affixed to or embedded in the base array 112. The LED array 110 has a width substantially the same as the distance between the first and second face walls 212, 222. The base strip 112 can be made of a flexible or deformable material, such as metal or some polymers. The base strip 112 is configured to be bent, curved, flexed, deformed, or otherwise permit a user to alter the shape of the light source 302 through application of a deformation force by the user to the light source 302 (e.g., it can be bent by hand), and then substantially retain a deformed state after the user stops applying the deformation force. Alternatively, base strip 112 can include a hinged substrate configured to bend the flexible panel 120 at joints in one direction with respect to the central array region 130. The flexible LED array 110 is configured to fold at the over the front rounded corners 252 to retract to the compact state and extend outward toward or away from the sides 206 of the housing 200. The flexible LED array 110 is also configured to be deformed into a stowed configuration in which the flexible panels 120 and the opposing end portions 114 are retained within the secure recesses 250, 260, adjacent to the face walls 212, 222. As such, the light source 302 is capable of being pivoted into multiple angles relative to the body 200, and can be bent into and retain its configuration after a user applies a deformation force to the lighting element. Such combinations of configurable pivot configurations and deformed deployment configurations allows the lighting device 10 to be used in multiple use configurations.
[0042] In the illustrated example, the LED array 110 is shown as a collection of three panels or arrays of illuminators, each having a collection of COB LEDs affixed to the base strip 112. In some embodiments, the LED array 110 can be a continuous, bendable lighting element. In some embodiments, the LED array 110 can include multiple discrete illuminators that are directly visible or may be covered by a translucent diffuser that can make the multiple lights have a substantially continuous and uniform luminous appearance. In some embodiments, the LED array 110 may be replaced by other forms of illuminators, such as incandescent lights, electroluminescent lights, laser illuminators, or combinations of these and any other appropriate form of light source.
Electronics Package
[0043] The electronics package 300 contained within the housing 200 of the wearable light 10 includes electronic components that are configured to control the operation mode of the light source 302. In connection with certain operation modes, the electronic components will emit light from the LED array 110 accordingly. The electronics package 300 includes the power source 320 and a light source PCB 310.
[0044] The light source PCB 310 is configured to supply power to the light source 310. For example, the light source PCB 310 may be configured to only illuminate a percentage of the emitters contained within the light source 310. For example, a user may be able to select the desired individual emitters that the user wants to illuminate, while keeping other individual emitters unilluminated, which can vary the brightness of the emitted light. In another embodiment, the light source PCB 310 may only supply a limited amount of power to all or a subset of the emitters. Lowering the suppled power will reduce the light that is emitted from the light source 310.
[0045] The light source 312 may be formed from various different types of emitter assemblies. For example, the light source 312 may be comprised of: (i) a standard LED, (ii) organic LED, (iii) induction light panel, (iv) silicon quantum dot phosphor (SiQD-phosphor), or (v) surface-mount device LED. In addition, different color emitters (e.g., red, green, blue) may be contained within the light source 312. Specifically, the light source 312 may be composed of between 1 and 60 individual emitters, preferably between 10 and 40 individual emitters, and most preferably between 15 and 30 individual emitters. In some embodiments, every individual emitter of light source 312 is configured to illuminate when power is applied to the light source 312 through switch 330. The primary light source 312 may produce between 0 and 3000 lumen, preferably between 0 and 1000, and most preferably between 0 and 300.
[0046] The light source PCB 310 is configured to supply power to the light source 310. For example, the light source PCB 310 may be configured to only illuminate a percentage of the emitters contained within the light source 310. For example, a user may be able to select the desired individual emitters that the user wants to illuminate, while keeping other individual emitters unilluminated, which can vary the brightness of the emitted light. In another embodiment, the light source PCB 310 may only supply a limited amount of power to all or a subset of the emitters. Lowering the suppled power will reduce the light that is emitted from the light source 302.
[0047] The control PCB 310 includes a charging/discharging port 340, which meets the USB-C standard. Meeting this standard allows the light 10 to: (i) receive electrical current from an external source (110 v wall outlet) in order to charge the internal power source 320 and (ii) supply electrical current from power source 320 to an external device such as a mobile phone. In other embodiments, the charging/discharging port 340 may only be a charging port or may only be a discharging port. For example, port 340 may take the form of a micro-USB port, which can only receive electrical current from an external supply and cannot discharge current to charge an external device. In an alternative embodiment, port 340 could be removed and the power source 320 could recharge through wireless recharging mechanisms or could provide power to an external device wirelessly. In yet another alternative embodiment, port 340 could be removed and the power source 320 could recharge through a photovoltaic panel arranged on one or more surfaces of the wearable light 10.
[0048] The switch 330 of the wearable lighting device 10 enables the user to alter the operational mode of the flexible LED array 110. This is done by altering the current that can pass from the power source 320 to flow to the flexible LED array 110 to illuminate or turn On the flexible LED array 110. In an example, the user: (i) may depress the switch 330 one time to turn On the flexible LED array 110, (ii) may depress the switch 330 two times to turn Off the flexible LED array 110, or (iii) may depress the switch 330 three times to place the flexible LED array 110 in a flashing or emergency mode. In some embodiments, the user may depress the switch 330 for a predetermined time and/or with a predetermined pattern of presses to adjust the emitted brightness and/or color of the light emitted by the flexible LED array 110. It should also be understood that switch 330 may be replaced with an assembly that is configured to utilize switches, sliders, or sensors physically coupled to the lighting element 100 (e.g., motion, light, sound, or heat). In other embodiments, the switch 330 may be replaced with an assembly that is configured to connect to any of the following devices using wired (802.11, FireWire, etc.) or wireless protocols (e.g., Bluetooth, Wi-Fi, NFC, etc.): (i) sensors (e.g., motion, light, sound, or heat) that are positioned at a distance from the wearable lighting device 10 or (ii) other devices (e.g., cell phone, laptop, RF remote control, etc.).
[0049] The power source 320 is configured to provide current to the flexible LED array 110. In particular, the power source 320 may be a non-removable, rechargeable battery. In other embodiments, the power source 320 may be a removable non-rechargeable battery, a removable rechargeable battery, a combination of removable rechargeable batteries, a combination of removable rechargeable batteries disposed within a battery cartridge, a combination of non-removable rechargeable batteries disposed within a battery cartridge, a DC power supply that is configured to connect to a 12-volt car battery, a DC power supply that is configured to connect to a 110-volt alternative current outlet, or any other type of power supply that is known to a person of skill in the art.
Attachment Means and Usage
[0050] In the figures, the attachment means 290 is shown as a clip 292 coupled to the first face wall 212 of the housing 200, which allows a user to releasably couple the wearable light 10 to clothing or other wearable or non-wearable items. The first flat outward facing surface 214 considered the attachment side of the device 10. Although shown as a curvilinear clip 292, the attachment means 290 may be an adhesive member, hook, magnetic coupler, hook and look fastener, or any other type of fastener that is designed to removably couple the wearable light 10 to an item. As shown in
[0051] Although shown attached to the hat 1000, the wearable light 10 can also be attached to other articles of clothing or other wearable or non-wearable items with the LED array 110 positioned according to the need. For example, the wearable light 10 positioned in the fully pivoted position may be clipped to or inserted into a pocket of a clothing article to illuminate a forward path of the user.
[0052] As shown in
[0053] The wearable light 10 also includes a detachable endcap 400. When coupled to the body 200, the endcap substantially encloses the base portion 270 and the USB charging port 340. The endcap 400 includes a loop 410. In some embodiments, the loop 410 can be used to removably affix the endcap 400 to a lanyard, tether, keychain, keyring, or any other appropriate accessory. The endcap 400 also includes a magnetic plate 420 configured to be magnetically attracted to the magnets 280. In use, the magnetic plate 420 removably couples the detachable endcap 400 to the body 200. For example, the wearable light 10 can be hung from a lanyard, and when the user needs light the user can simply give the wearable light 10 a tug to magnetically detach the body 200 and the deployable lighting element 100 from the detachable endcap 400 and the tether. When done, the user can simply insert the body 200 back into the detachable endcap 400 to be stowed for future use. In some embodiments, with the detachable endcap 400 in place, the magnets 280 can also be prevented from unintentionally attaching to or unintentionally attracting other magnetically reactive objects (e.g., metal objects in a pocket, a car door as the user enters or exits a vehicle).
