The multi-element flexible strap light includes a power port for receiving power from a remote battery.
2. Description of the Related Art
Human eyes are particularly sensitive to light. Accordingly, mankind has developed different ways of providing artificial light in darkness. Originally, artificial light was provided by flame based devices, including pitch torches, fuel based lanterns, candles, and other examples. Since the advent of electricity, artificial light has been provided by flashlights and electric battery powered lanterns.
More recently, artificial light has been provided by flashlights that use LED (light emitting diode) technology. LED technology provides reasonably bright light while using relatively low electrical current. More simply, the use of LED technology provides more light for less electrical power than conventional incandescent (bulb and filament) light technology. LED technology also has the advantage of providing more artificial light than conventional incandescent light technology in a smaller physical footprint. More simply, the use of LED technology provides for more light in less physical space than conventional incandescent (bulb and filament) light technology. Because a relatively large amount of artificial light can be generated by a small flashlight, many flashlight form factors have been developed to provide light during a variety of activities or situations.
For example, headlamps have been developed which essentially attach a flashlight to a user's head via an elastic strap. Many users find headlamps helpful because when a headlamp is placed on a user's forehead, a headlamp always points in the direction of a user's eyes. Thus, anything the user looks at is illuminated by the headlamp. While headlamps can be useful, headlamps fail when used in proximity to other people. For example, if a headlamp user looks at another person, the light from the headlamp shines into the other person's eyes, causing the person pain or desensitizing the person's eyes to low amounts of light.
Another example of a popular flashlight form factor which uses LED technology may include a reflector light. Reflector lights typically have several LEDs (light emitting diodes) designed to make a user more visible to other people. Typically reflector lights that are designed to face forward are implemented to emit white light while reflector lights that are designed to face rearward are implemented to emit red light. Reflector lights are typically used by bikers, joggers, or other users exercising along busy roadways in an effort to make themselves more visible to drivers. Conventional reflector lights may include clips that may attach to a user's clothing, shoes, equipment, or hat. Unfortunately, these clips are generally hard to use and, in many cases, do not remain in a fixed position while the bikers, joggers, or other users are participating in their chosen activity. For example, reflector lights tend to move or fall off as a user runs. This movement in the reflector lights can obscure the light and make the bikers, joggers, or other users less visible than they may believe themselves to be, potentially leaving these bikers, joggers, or other users in more danger than they expect.
Electrical flashlights and lanterns also conventionally rely on local battery power. For example, the flashlight or the lantern itself contains or houses a battery that powers the LEDs associated with the flashlight or the lantern. While, in some cases, it may be convenient to house a battery inside the flashlight or the lantern, many flashlights or lanterns either require additional physical space to house the batteries or use small batteries that have limited current capacity (which in turn limits available brightness of emitted light).
Finally, conventional electrical flashlights and lanterns generally have restrictive beam patterns. For example, an electrical flashlight may emit a beam of light in a particular direction with a beam width of 10 degrees. Thus, in the example of an electrical flashlight, a user may have to scan an object from side to side and top to bottom to see the object with sufficient clarity. The electrical flashlight typically illuminates objects that are farther away than does a lantern but provides light in substantially less physical area around the user. A lantern, however, may emit light with a beam width of 360 degrees. Thus, in the example of an electrical lantern, a user may have to closely approach an object to see the object with sufficient clarity. The electrical lantern typically illuminates objects that are relatively close to a user and provides light in substantially more physical area around the user but fails to adequately illuminate objects that are farther away from a user.
Thus, while electrical flashlights and lanterns provide some utility in various situations, neither electrical flashlights nor lanterns are useful in some situations. For example, electrical flashlights cannot illuminate an entire campsite while an electrical lantern cannot illuminate a significant length of a trail. Thus, in many cases, it has been advisable to use both an electrical flashlight and a lantern to illuminate a dark area.
It is therefore one object of this disclosure to provide a multi-element flexible strap light. It is a further object of this disclosure to provide multi-element flexible strap light with a relatively small physical footprint. It is a further object of this disclosure to provide a multi-element flexible strap light that emits light in a direction that is low enough to not adversely affect other people.
It is a further object of this disclosure to provide a multi-element flexible strap light that firmly attaches to a user's clothing, equipment, shoes, or hat without movement during the user's activities. It is a further object of this disclosure to provide a multi-element flexible strap light with a remote battery, reducing the overall physical size of the multi-element flexible strap light. It is a further object of this disclosure to provide a multi-element flexible strap light that emits light in a particular direction while also emitting light in a wider area around a user than conventional technologies.
In one embodiment, a multi-element flexible strap light is disclosed which includes a plurality of light elements disposed on a flexible chassis. The chassis may include a first flexible layer, a printed circuit board, and a second flexible layer. The flexible chassis may be further contained within a third flexible layer, such as a layer of polycarbonate plastic.
Further disclosed is a multi-element flexible strap light system which includes a plurality of light elements disposed on a flexible chassis and a remote battery. The flexible chassis may include a first flexible layer, a printed circuit board, and a second flexible layer. The flexible chassis may be further contained within a third flexible layer, such as a layer of polycarbonate plastic.
The accompanying drawings illustrate several embodiments of the multi-element flexible strap light. The illustrated embodiments are exemplary and do not limit the scope of the disclosure.
In the following description, for purposes of explanation and not limitation, specific techniques and embodiments are set forth, such as particular techniques and configurations, in order to provide a thorough understanding of the device disclosed herein. While the techniques and embodiments will primarily be described in context with the accompanying drawings, those skilled in the art will further appreciate that the techniques and embodiments may also be practiced in other similar devices.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts. It is further noted that elements disclosed with respect to particular embodiments are not restricted to only those embodiments in which they are described. For example, an element described in reference to one embodiment or figure, may be alternatively included in another embodiment or figure regardless of whether or not those elements are shown or described in another embodiment or figure. In other words, elements in the figures may be interchangeable between various embodiments disclosed herein, whether shown or not.
Control element 110 may include a combination of one or more application programs and one or more hardware components. For example, application programs may include software modules, sequences of instructions, routines, data structures, display interfaces, and other types of structures that execute operation. Further, hardware components may include a combination of CPUs (central processing units), buses, volatile and non-volatile memory devices, non-transitory computer readable memory device and media, data processors, control devices, transmitters, receivers, antennas, transceivers, input devices, output devices, network interface devices, and other types of components that are apparent to those skilled in the art.
Control element 110 interfaces with a user to exert control over light elements 105a-105e. In one embodiment, control element 110 may provide multiple modes for light elements 105a-105e. For example, control element 110 may include a mode that allows a user to vary a brightness setting of light elements 105a-105e. In another embodiment, control element 110 may include a mode that allows a user to select a strobe mode for light elements 105a-105e. In addition, control element 110 may include a mode that allows a user to both select a strobe mode and a brightness mode for light elements 105a-105e. Further, control element 110 may include a mode that allows a user to both select a strobe mode and a frequency mode for light elements 105a-105e to control the speed at which light elements 105a-105e flash in the strobe mode. Control element 110 may further be configured to allow a user to select any or all of a strobe mode, a brightness of light elements 105a-105e in strobe mode, and a frequency of the strobe.
Control element 110 may further be configured to perform a power calibration test based on power levels detected by control element 110 from a remote battery via power port 120. In one embodiment, control element 110 may determine a power (voltage/current) level that is available and adjust the brightness of multi-element flexible strap light 100 accordingly. Thus, the brightness of multi-element flexible strap light 100 may be monitored and adjusted by control element 110 to provide the brightest available setting for light elements 105a-105e based on a level of power available from the remote battery.
Mode switch 115 may be implemented as a single switch or a single button disposed within control element 110. The duration of a button press, for example, may select one of the aforementioned modes of operation in control element 110. In other words, an exemplary implementation may select a brightness control mode by pressing mode switch 115 for 3 seconds. In response, control element 110 may begin varying the brightness of light elements 105a-105e from the dimmest setting to the brightest setting. A particular brightness setting may be selected, for example, when the user releases mode switch 115 at a particular brightness setting.
Power port 120 may be implemented using any connector known in the art and may include data communication connections. In one embodiment, power port 120 may be implemented as a micro-USB connector including one of a micro-A and micro-B USB connector. However, power port 120 may be implemented using mini-USB connectors (both mini-A, and mini-B), USB-A connectors, USB-B connectors, USB-C connectors, barrel connectors, and any other connector known in the art. Power port 120 may receive power, through a wired connection, from a remote battery. In one embodiment, a battery may be disposed in a backpack or a pocket and may be connected to control element 110 via power port 120. Control element 110 may operate using power derived via power port 120 from a remote battery. As used herein, the term “remote battery” means a battery that is not integral to multi-element flexible strap light 100. Rather, a remote battery is connected to multi-element flexible strap light 100 via a wired connection between the remote battery and power port 120. By connecting multi-element flexible strap light 100 to a remote battery, more brighter light can be provided for a longer period of time than conventional electric flashlights and lanterns that contain local battery power. In one example, a user may carry the remote battery in a pocket, in a carrying case, or the user may strap the battery to, for example, the user's arm. Myriads of other ways of carrying a remote battery that may connect to power port 120 may be apparent.
Control element 110 is directly electrically connected to light elements 105a-105e via a PCB (printed circuit board) contained within a flexible chassis 125. In other words, control element 110 may be mounted on or around at least a portion of flexible chassis 125. Flexible chassis 125 will be discussed in more detail below. However, flexible chassis 125 allows multi-element flexible strap light 100 to conform to various curves and emit light in a plurality of directions. As will be discussed below, flexible chassis 125 may conform to the curvature of a backpack strap as it is worn, for example.
In one embodiment, light element 205a, for example, may include two magnets such as rare earth magnet 225a and rare earth magnet 225b. Similarly, light element 205b may include rare earth magnet 225c and rare earth magnet 225d. Light element 205c may include rare earth magnet 225e and rare earth magnet 225f. Light element 205d may include rare earth magnet 225g and rare earth magnet 225h. Light element 205e may include rare earth magnet 225i and rare earth magnet 225j. Each of rare earth magnets 225a-225j are disposed on an anterior side of a corresponding light element 205a-205e and disposed on opposite sides of light elements 205a-205e along an axis of light elements 205a-205e that is perpendicular to flexible chassis 220.
Rare earth magnets 225a-225j may be used to connect multi-element flexible strap light 200 to any metal object. For example, multi-element flexible strap light 200 may connect via rare earth magnets 225a-225j to the hood of a car, to a work bench, or another work light implementation. Multi-element flexible strap light 200 may further function as an under counter cabinet light, a bar light, a night light, or any other situation where multi-element flexible strap light 200 may connect to a metal via rare earth magnets 225a-225j. The polarities of rare earth magnets 225a-225j are configured such that two of multi-element flexible strap light 200 may be magnetically connected to each other back to back.
Light element 305 may include a lens 310. In one embodiment, lens 310 may be a TIR (Total Internal Reflection) lens or may be constructed using a polycarbonate plastic, glass, or any other material suitable to focus light. In one embodiment, lens 310 may be colored or include a light filter to change the color of the light emitted by multi-element flexible strap light 300. For example, lens 310 may be tinted red or include a red filter to cause red light to be emitted from multi-element flexible strap light 300.
Light element 305 further includes an LED 315. LED 315 may be a super bright LED capable of emitting up to approximately 800 lumens of light at maximum conditions. Accordingly, LED 315 may be thermally connected to light element 305 to draw heat away from LED 315 and dissipate that heat into the ambient air through the metal which makes up light element 305. In one embodiment, one or more surfaces of light element 305 may include one or more heat sink fins which increase surface area of light element 305 and thereby expose more heat to more air, which serves to more quickly dissipate heat. LED 315 may be connected to flexible chassis 320 which provides power to LED 315.
In one embodiment, an anterior portion of light element 405 may be connected to a posterior portion of light element 405 by screw 415a, screw 415b, screw 415c, and screw 415d. Screws 415a-415d may thread into the anterior portion of light element 405 through the posterior portion of light element 405, thereby securely holding the anterior portion of light element 405 to the posterior portion of light element 405 around an LED, such as LED 315 shown in
Multi-element flexible strap light 500 further illustrates power port 520. Power port 520 may be implemented as a micro-USB connector including one of a micro-A and micro-B connector. However, power port 520 may be implemented using mini-USB connectors (both mini-A, and mini-B), USB-A connectors, USB-B connectors, USB-C connectors, barrel connectors, and any other connector known in the art. Power port 520 may connect to a remote battery to provide power to multi-element flexible strap light 500.
First and second flexible layers 605a and 605b are disposed on opposite sides of PCB 610 to allow flexible chassis 600 to flex. In other words, flexible chassis 600 may flex to follow a curve, such as the curve of a backpack strap over a user's shoulder. In an extreme example, flexible chassis 600 may flex in an arc to about 180 degrees. As flexible chassis 600 flexes, the angle and direction of light emitted by LEDs 615a-615e changes. For example, as the degree of bend between any two of LEDs 615a-615e increases, the angle of the light emitted by LEDs 615a-615e widens, broadening the area into which light is emitted. Thus, a user who desires more direct light at a longer distance may dispose multi-element flexible strap light 100 on a non-curved or substantially non-curved surface. A user who desires to cast light into a broader area at a shorter distance may dispose multi-element flexible strap light 100 on a curved or substantially curved surface.
In one embodiment, a user may attach multi-element flexible strap light 100 to an article of clothing using magnetic backer 700a. For example, a user may dispose the multi-element flexible strap light 100 on the outside of a jacket and hold the multi-element flexible strap light 100 in place on the jacket by disposing magnetic backer 700a on the inside of the jacket in a position corresponding to the position of multi-element flexible strap light 100 on the outside of the jacket. Accordingly, multi-element flexible strap light 100 may be held in place on any article of clothing by magnetic backer 700a.
Magnetic backer 700b and magnetic backer 700a may be used in the same fashion. Accordingly, a user may dispose a light source in any location on the user's person. A hiker, for example, may dispose multi-element flexible strap light 100 vertically on a shirt or horizontally along a hat. Other applications for the magnetic attachment of multi-element flexible strap light 100 to magnetic backer 700a or magnetic backer 700b include people participating in activities such as walking, running, mountain biking, lighting a campsite, lighting a tent, cross country skiing, downhill skiing, snowshoeing, caving, road biking, climbing, rappelling, hunting, fishing, or any other activity which may be performed during a dark portion of a day. Multi-element flexible strap light 100 and magnetic backer 700a and magnetic backer 700b may further be used on a dog collar or may be installed on children's clothing or equipment while they are walking to school, for example. In any implementation, magnetic backer 700a and magnetic backer 700b hold multi-element flexible strap light 100 securely in place during the activity.
Strap 900 attaches to a multi-element flexible strap light, such as multi-element flexible strap light 100 discussed above and shown in
In implementation, hook and loop tape straps 925a-925e may connect to themselves by means of hooks and loops disposed on alternate sides of the hook and loop tape straps around the multi-element flexible strap light. In one embodiment, each of hook and loop tape straps 925a-925e may connect to themselves between control element 915 and light element 920a or between light elements 920a-920e. In this manner, hook and loop tape straps 925a-925e secure multi-element flexible strap light 100 to strap 900. Once hook and loop tape straps 925a-925e secure multi-element flexible strap light 100 to strap 900, D-ring 905a and D-ring 905b may be used to connect multi-element flexible strap light 100 to, for example, a backpack strap. In another embodiment, hook and loop tape straps 925a-925e may connect around a backpack strap and a multi-element flexible strap light 100 simultaneously to secure multi-element flexible strap light 100 to a backpack strap.
Strap 900 may be used in any activity discussed herein, such as those discussed above with respect to magnetic backer 700a and magnetic backer 700b discussed in
In this fashion, beam pattern 1000 provides light in a wide area while at the same time providing light over a substantial distance, when compared with conventional electric flashlights. Because multi-element flexible strap light 100, for example, has the ability to flex, the beam width may be adjusted by flexing the multi-element flexible strap light in a certain implementation, as desired by a user and according to the specific activity engaged in by the user.
