DETAILED DESCRIPTION

The present disclosure more fully describes various embodiments with reference to the accompanying drawings. It should be understood that some, but not all embodiments are shown and described herein. Indeed, the embodiments may take many different forms, and accordingly this disclosure should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

A lighting device as discussed herein incorporates one or more storage areas that may be closed (e.g., via a lid) to enclose various items therein. The light emitted by the lighting device is not impeded by items stored within the storage area. The storage compartments of certain embodiments define a plurality of divided storage areas that may each store various items therein. These divided storage areas may be separated from one another, such that items stored within a first divided storage area cannot contact items stored within a second divided storage area. In certain embodiments, at least one storage area is a removable tray that may fit within an interior storage compartment of the lighting device. The tray may be supported above a bottom surface of the interior of the storage compartment of the lighting device by standoffs integrated into the interior walls of the storage compartment, to define a second storage area between the bottom surface of the interior of the storage compartment and the bottom surface of the tray. Certain embodiments may comprise more than one storage tray. In certain embodiments, the one or more storage areas may omit the removable storage tray, such that the one or more storage areas is embodied as a single storage space.

The lighting device additionally comprises one or more light sources (e.g., Light Emitting Diodes (LEDs)). The one or more light sources may be positioned within the lighting device such that light emitted from the one or more light sources surrounds the storage area. In certain embodiments, the one or more light sources may be positioned under the storage area (e.g., within a base of the device), such that light emitted from the one or more light sources surrounds the storage area. In various embodiments, one or more light pipes, such as those discussed in U.S. Pat. No. 8,317,366, which is incorporated herein by reference, may be utilized to guide light from the light source to the sidewalls of the device. In certain embodiments, the one or more light sources may surround a perimeter of the storage area and may be housed within an illumination portion of the lighting device. The illumination portion may be a translucent (or transparent) material for diffusing light produced by the light sources. Those light sources are powered by an onboard power source, which may comprise at least one of: onboard rechargeable electrochemical cells and/or a compartment for housing replaceable electrochemical cells (e.g., primary alkaline, lithium, or other electrochemical cell types) such that those replaceable cells may be used as an onboard power source of the device. In certain embodiments, the lighting device additionally comprises an onboard controller for determining which onboard power source should be utilized when the lighting device is powered on.

In certain embodiments, the lighting device may additionally comprise one or more electrical connections for detachably connecting one or more separate electrical devices. Accordingly, the lighting device may be usable as an auxiliary power source for connected devices, such as to recharge batteries onboard those separate devices. In certain embodiments, the onboard controller may be configured to optimize charging of connected devices while simultaneously providing light via the onboard light sources when a separate device is connected. For example, the lighting device may be configured to limit the maximum brightness permitted while charging to a level below the overall maximum brightness of the lighting device.

In certain embodiments, the lighting device additionally comprises a second light emitting component that may be integrated into a lid of the device. The second light emitting component may be physically separable from the first light emitting component, and may be used independently of the first light emitting component. The second light emitting component may thus have an onboard power supply (e.g., a rechargeable battery, or a compartment for housing replaceable (e.g., primary) batteries for powering the device. It should be understood, however, that in certain embodiments, the lid of the device may not include a light emitting component.

Multi-Purpose Lighting Device

An example lighting device10is shown inFIGS.1A-1B. As shown therein, the lighting device10may be embodied as a lantern having a generally cube-shape. As shown, the lighting device10has a generally square cross-sectional shape (defined by the length and width of the device) and has a height that is taller than the length or the width. It should be understood that other dimensions and/or shapes may be provided. For example, a cylindrical body may be provided in certain embodiments. Other shapes, such as trapezoidal, octagonal, and/or the like may be provided while maintaining the functionality discussed herein.

The lighting device10defines an interior storage space accessible by removing a lid from the main body portion of the lighting device10. In the illustrated embodiment ofFIGS.1A-1B, the main body portion is embodied as a first light emitting component12and the lid is embodied as a second light emitting component14configured for being removably coupled to the first light emitting component12, as shown inFIG.1B. Each of the first light emitting component12and the second light emitting component14are configured for emitting a light output. In the embodiment ofFIG.6B, discussed in greater detail herein, the lighting device10additionally includes a tray17that may fit within the interior storage space of the lighting device.

First Light Emitting Component

Referring now toFIGS.2-4, the first light emitting component12may comprise a housing20defining a hollow interior18having an open first end21and one or more sidewalls22surrounding the open first end21. In the depicted embodiment ofFIGS.2-4, the housing20has a square shape (e.g., substantially square shape). However, the housing20may have other shapes as mentioned previously (e.g., rectangle, circle, oval, and/or the like). The first light emitting component12may comprise a handle31pivotably coupled to the to the housing20via one or more attachment members32(e.g., bolts, rivets, hooks, clips, fasteners, and/or the like) configured to enable pivotable movement of the handle between a deployed orientation (e.g., in which handle31is extending at least substantially vertically) and a collapsed orientation (e.g., in which the handle is resting against the housing20). The handle31may pivot freely about the attachment members32. However, it should be understood that in certain embodiments, the handle31may be coupled to the housing20, such that the handle31is not pivotable. As shown inFIG.2, the handle31may be coupled to the housing20proximate to an upper portion of the housing20. However, various embodiments may include any of a variety of other lifting mechanisms, such as straps, clips, hooks, and/or the like (in an alternative to or in addition to the handle), and various embodiments may not include a handle coupled to the housing20.

As shown inFIG.3, the housing20comprises a light-transmissive portion15and a base13. In the embodiment shown, the light-transmissive portion15surrounds an open first end21of the housing, which exposes the interior storage compartment of the lighting device10. The light-transmissive portion15is connected with (e.g., sealed with) the base13, located on an opposite, bottom end of the lighting device10. In certain embodiments, the light-transmissive portion15comprises a transparent material or a translucent material configured to diffuse light emitted by included light sources. In certain embodiments, the light-transmissive portion15extends up to and includes at least a portion of a top surface of the housing20. In other embodiments, the light-transmissive portion15encompasses only sidewall portions of the housing20, with the top surface of the housing being opaque. It should be understood that various designs (e.g., with opaque, transparent, and/or translucent portions) may be embodied within the light-transmissive portion15. Moreover, the light-transmissive portion15may comprise materials of one or more colors (e.g., white, red, orange, and/or the like), such that the light-transmissive portion15may operate to filter the wavelengths of light emitted by the lighting device10.

As shown, the housing defines a sealed region between outer walls of the lighting device (the outermost surface of the lighting device) and inner walls of the lighting device (defining the interior storage compartment). The sealed region encompasses a region within the light-transmissive portion15and the base13. The sealed region may be sealed via an adhesive, a gasket, one or more interference fit clips, and/or the like. The sealed region may be water-proof or water-resistant. One or more first light sources24may be disposed within the sealed region of the housing20(e.g., within the base) to emit light through a light-transmissive portion15.

In certain embodiments, the one or more first light sources24may comprise one or more light emitters (e.g., light emitting diodes (LEDs)). In the noted embodiments, in which the one or more first light sources24comprise one or more LEDs, the one or more LEDs may be disposed within the housing20has an array of LEDs exterior to the opaque side25of the one or more sidewalls22. Moreover, in the embodiments in which the one or more first light sources24comprise one or more LEDs, the one or more first light sources24may, collectively, be configured for emitting light according to one or more wavelengths (e.g., various colors). For example, the one or more first light sources24may comprise one or more first light sources configured to emit light according to a first wavelength (e.g., a first color), and one or more second light sources configured to emit light according to a second wavelength (e.g., a second color). As a specific example, the one or more first light sources24may comprise one or more light sources (e.g., white LED) configured to emit white light, and one or more light sources (e.g., red LED) configured to emit red light, and may be configured for simultaneous illumination and/or alternative illumination, thereby providing a plurality of alternative lighting modes. In the noted example, the lighting device10may be configured to activate the red LED via a first lighting mode (e.g., a red light mode) for the first light emitting component12or the one or more white LEDs (e.g., a plurality of white LEDs) via a second lighting mode (e.g., a white light mode) for the first light emitting component12in the alternative.

The first light sources24may be spaced around a perimeter of the lighting device10, within the sealed region. As shown inFIG.3, the first light sources24are disposed on substrates (e.g., printed circuit boards (PCBs)24athat are aligned with linear sidewall portions. Each linear sidewall portion has a corresponding substrate, and thus in the illustrated embodiment, the lighting device10comprises four substrates. Moreover, in the illustrated embodiment, each substrate has four LEDs disposed thereon, for a total of 16 first light sources24. It should be understood that a greater or lesser number of lighting sources may be utilized in other embodiments. Moreover, while the embodiment illustrated inFIG.3includes multiple substrates, it should be understood that a single substrate may be utilized in other embodiments.

As specifically shown inFIGS.3and4, the sealed region may be defined within a portion of the one or more sidewalls22comprising a light-transmissive side23defining an outer sidewall of the one or more sidewalls22, and an opposite, opaque side25defining an inner sidewall22aof the one or more sidewalls22. As discussed above, the light-transmissive side23(which may be transparent or translucent) defining an outer sidewall22bof the one or more sidewalls22enables light generated by the one or more first light sources24disposed (e.g., located) within the sealed portion of the housing20to be emitted through the light-transmissive side23to be discernable by a user. In certain embodiments, the opaque side25may be embodied as a removable, opaque liner for the storage compartment of the lighting device10. In other embodiments, the opaque side25may be affixed (e.g., permanently affixed) relative to the light-transmissive portion15. As shown inFIG.3, the one or more first light sources24may be disposed within the light-transmissive portion15along a perimeter of the opaque side25defining an inner sidewall of the one or more sidewalls22and proximate to a lower end of the light-transmissive portion15.

The inner sidewall22aof the one or more sidewalls22may be embodied as the opaque liner for the storage compartment. When the liner is placed within the storage compartment (removably or permanently) the one or more inner sidewalls22ahave an edge25asurrounding the inner sidewall22athat is lower than an edge23asurrounding the outer sidewalls22b, and as further described herein, the edge of the inner sidewall22amay be configured to support the second light emitting component14(e.g., embodying a lid of the device) when the second light emitting component14is nested within the open end of the first light emitting component12. Moreover, as shown inFIG.3, the opaque inner sidewalls22amay define at least one light-passthrough26extending at least through the opaque side25defining the inner sidewall22a. As further described herein, the at least one light-passthrough26may be configured to enable light from the second light emitting component14to be visible through at least a portion of the one or more sidewalls22when the second light emitting component14is nested within the open end of the first light emitting component12. Thus, if a user accidentally left the second light emitting component14activated after nesting the second light emitting component14into the open end of the first light emitting component12, the user can see that the light is still active, and can then deactivate the second light emitting component14. As a specific example, the at least one light-passthrough26may comprise one or more openings26defined by the inner sidewall22a. In other embodiments, the one or more light-passthrough26may comprise a light-transmissive portion (e.g., translucent or transparent) defined within the opaque inner sidewall22a, while maintaining a smooth and/or fluid-impermeable surface of the inner sidewall22a. Thus, the sealed region remains sealed to prevent/impede water intrusion into the area housing the LEDs.

FIG.5illustrates the hollow interior18defined by the housing20(e.g., defined by the inner sidewall22aof the one or more sidewalls22of the housing20). As shown, the hollow interior18defines one or more storage spaces18a(e.g., storage compartments) configured for storing various items, such as emergency kit items18b(e.g., flashlights, batteries, headlamps, and/or the like) and/or other items. Moreover, the lighting device10may include a storage unit (e.g., tray) removably disposed within the hollow interior18, as shown inFIGS.6A and6B(6B showing a tray17removed from the interior of the lighting device10). The hollow interior18may comprise one or more support members18d(e.g., one or more thin standoffs having substantially flat top surfaces that collectively (across all standoffs) support the tray17above the inner bottom end18cof the interior surface) extending upwardly from an inner bottom end18c(surrounded by the inner sidewall22aof the housing20and protruding outwardly incrementally from the inner bottom end18c.

As shown inFIGS.1-5, the lighting device10comprises a user interface (embodied as a power switch/button27in the illustrated embodiment) configured to accept user input to select from a plurality of usage states for the first light emitting component12of the lighting device10. The user interface may comprise one or more buttons, one or more sliders, one or more switches, one or more interface wheels, one or more capacitive sensors, and/or the like. In various embodiments, the user interface enables a user to select between an “on” state (e.g., a single “on” state at a non-selectable power level) and an “off” state. The user interface may, in certain embodiments, enable toggling between a plurality of “on” states corresponding to various output modes (e.g., a red light mode or a white light mode) and/or various output power levels (e.g., various brightness levels emitted by the one or more first light sources24of the illustrated lighting device10). As a specific example, the various output power levels may comprise a high brightness level, a low brightness level, a dimming brightness level, and a night light brightness level emitted by the one or more first light sources24.

In certain example embodiments, a single button user interface may allow users to cycle between an “off” state and various “on” states with sequential activations of the button. For example, pressing the button once turns the light on to a first lighting mode (e.g., a red light mode), pressing the button again changes the light to a second lighting mode (e.g., a white light mode) at a first brightness level, and pressing the button a third time changes the light to a second brightness level within the second lighting mode, and pressing the button yet again cycles the light back to the off state. Certain other example embodiments may comprise only a single lighting mode, and therefore pressing the user-interface button multiple times may cycle the light through various brightness levels within a single lighting mode (e.g., within a white light mode). In certain other embodiments, the user interface may comprise a first power switch (e.g., to turn the first light emitting component12of the lighting device10on and/or off) and a second power switch (e.g., to select between a plurality of illumination states).

As shown inFIG.6A, the first light emitting component12of the lighting device10comprises at least one charging channel configured for providing power (e.g., electrical current) from the lighting device10to a separate electrical device50(shown schematically inFIG.7) connected via the charging channel. In the illustrated embodiment ofFIG.6a, the charging channel is embodied as a charging channel port28(e.g., a USB-port, a micro-USB port, a mini-USB port, a USB-C port, a lightning charger port, and/or the like) configured to accept an electrical device50(e.g., a charging/data cable, an electrical device comprising an onboard, rechargeable power source, and/or the like) and is carried by the housing20. However, the charging channel may also be embodied as any of a variety of power-communicating interfaces, such as a wireless inductive charging interface, a magnetic power port, a two-prong power outlet, and/or the like. In certain embodiments, an onboard controller30may be configured to automatically dim the output light of the device when an external device is connected to be charged, as described in U.S. Pat. No. 10,433,396, which is incorporated herein by reference in its entirety.

As shown schematically inFIG.7, the lighting device10comprises a power source29(first power source), which may be embodied as an onboard power source comprising one or more batteries (e.g., replaceable primary batteries or rechargeable secondary batteries (integrated within the lighting device10or replaceable secondary batteries)) or other electricity storage devices. For example, in certain embodiments, the lighting device10may comprise an onboard power source usable with the light sources to generate a light output of at least about 1000 lumens. As a specific example, the lighting device may comprise an onboard power source embodied as a 4800 mAh rechargeable battery and 3 AA primary batteries that may be inserted into a corresponding slot to house the primary batteries. As another specific example, the lighting device may comprise an onboard power source embodied as 4 replaceable D-cell batteries. It should be understood that embodiments may be configured to house other numbers or sizes of batteries. As yet another example, the power source29may comprise one or more power converters (e.g., connectable to external, continuous power supplies), and/or the like. The power converters may be utilized to power the light source and/or to recharge onboard power sources. The power source29is disposed within the base13of the housing20.

The power source29provides power to an output device configured for generating an output (e.g., first light emitting component12configured for generating a light output) and the at least one charging channel (e.g., charging channel port28) via a controller30. In certain embodiments, the controller30is embodied as an integrated circuit configured for directing a flow of electrical power (e.g., electrical current) from the power source29to the output device and/or the at least one charging channel. The controller30is in communication with the user interface27to direct power from the power source29to the lighting device output.

The controller30may also form a feedback loop with the charging channel to detect when a separate electrical device50is connected for charging from the lighting device10. In embodiments in which the charging channel is embodied as a charging channel port28, the charging channel port28may comprise a presence sensor for detecting when the lighting device10is connected to the charging channel port28. For example, the charging channel port28may comprise a presence-sensing pin that transmits a signal upon detecting a connected separate electrical device50to the onboard controller30to indicate the presence of the separate electrical device50in electrical connection with the charging channel port28. One particular embodiment of a charging channel port28is a 5 pin USB connector. As yet other examples, the charging channel may comprise mechanical switches for detecting the presence of a separate electrical device50(e.g., cables connected via the charging channel), magnetic switches, current-sensors for detecting an electrical current drawn across the charging channel to a connected separate electrical device50, and/or the like.

The onboard controller30may be configured to control the electrical power expended by the lighting device10for generating outputs via the output device (e.g., one or more first light sources24) and for charging separate electrical devices50via the charging channel. In certain embodiments, the onboard controller30may be configured to throttle electrical power (e.g., by decreasing a permitted maximum constant current to be provided to the output device, by decreasing the width of power-pulses provided to the output device via pulse-width modulation, and/or the like) supplied to the output device (e.g., first light emitting component12), thereby decreasing the output power level emitted by the output device when a separate electrical device50is detected to be connected via the charging channel. For example, the onboard controller30may be configured to implement a maximum constant current level to be provided to the output device that is lower than a maximum constant current level implemented while no separate electrical device50is connected relative to the charging channel, thereby decreasing the output power level generated by the output device (e.g., dimming the output light emitted by the lighting device10). As yet another example, the onboard controller30may be configured to provide pulse-width modulated current pulses to the output device at shorter power intervals as compared to the length of power intervals provided when no separate electrical device50is connected via the charging channel, which thereby decreases the output power level generated by the output device. For example, using pulse-width modulation, the light emitted by the output device may be less bright when a separate electrical device50is connected via the charging channel as compared to the brightness when a separate electrical device50is not connected via the charging channel. Specifically, when a separate electrical device50is detected to be connected via the charging channel, the onboard controller30decreases the power provided to the output device if the output device is active at the time the electrical connection is formed with the separate electrical device50via the charging channel, and/or the onboard controller30decreases a maximum output power level available for the onboard output device (e.g., lighting device10).

Second Light Emitting Component14

Referring now toFIGS.8-11, the second light emitting component14may comprise a body60defining a first end62and a second end63. At least a portion of the first end62defines a light emitting portion64and one or more second light sources65(e.g., light bulbs, light filaments, light panels, and/or the like) may be disposed (e.g., located) within the body60to emit light through the light emitting portion64. As shown inFIGS.10-11, the light emitting portion64may be defined by a lens portion66of the body60. The lens portion66may cover the one or more second light sources65and may be transparent (as shown inFIG.11) or translucent (as shown inFIG.10) to enable light generated by the one or more second light sources65to be emitted through the lens portion66to be discernable by a user. As a specific example, the one or more second light source65may comprise one or more light emitters (e.g., light emitting diodes (LEDs)).

In certain embodiments in which the one or more second light sources65comprise one or more LEDs, the one or more second light sources65may, collectively, be configured for emitting light according to one or more wavelengths (e.g., various colors). For example, the one or more light sources65may comprise one or more second light sources configured to emit light according to a first wavelength (e.g., a first color), and one or more second light sources configured to emit light according to a second wavelength (e.g., a second color). As a specific example, the one or more second light sources65may comprise one or more second light sources (e.g., white LED) configured to emit white light, and one or more second light sources (e.g., red LED) configured to emit red light, and may be configured for simultaneous illumination and/or alternative illumination, thereby providing a plurality of alternative lighting modes. In the noted example, the lighting device10may be configured to activate the red LED via a first lighting mode (e.g., a red light mode) or the one or more white LEDs (e.g., a plurality of white LEDs) via a second lighting mode (e.g., a white light mode) in the alternative.

The second light emitting component14may comprise a handle67having a first side71and second side72. In certain embodiments, such as the illustrated embodiment ofFIGS.8-10, the handle67may be pivotally coupled to a recessed portion68of the body60via one or more attachment members that enables movement of the handle67between a deployed orientation (e.g., standing orientation) and a collapsed orientation (e.g., folded orientation). The recessed portion68may have a depth that is at least the same (or greater) than a thickness of the handle67, and may comprise a first curved portion69and a second curved portion70having a diameter that is greater than a diameter of the first curved surface to enable the handle67to be supported by the first curved portion69when in the deployed orientation and disposed within the second curved portion70when in the collapsed orientation.

In certain embodiments, the handle67and the recessed portion68may be sized and/or dimensioned such that when the handle67is in a collapsed orientation, the first side71of the handle67is parallel with an edge surrounding the recessed portion68of the body60. It should be understood, that in various embodiments, the handle67may have a different shape and the recessed portion68may not comprise a first curved portion69and a second curved portion70. For example, in one embodiment, the handle67may have a square shape and the recessed portion68may comprise a first square-shaped portion and a second square-shaped portion having different lengths. Further, it should be understood that various embodiments may not include a handle67, and may instead include any of a variety of other support mechanism or lifting mechanisms, such as straps, clips, loops, hook-and-loop fasteners, and/or the like.

The handle67may include a hook member74configured for being coupled to a support structure (e.g., to suspend the second light emitting component from a support structure). The hook member74may be pivotally secured to a first end75of a recessed portion76of the handle67via one or more attachment members that enables movement (e.g., swivel fashion) of the hook member74between a deployed orientation and a collapsed orientation. The recessed portion76may include a lip78configured for supporting the hook member74when in a collapsed orientation.

The second light emitting component14comprises a user interface (embodied as a power switch80in the illustrated embodiment). In the illustrated embodiment, the user interface is disposed within the recessed portion68of the body60. The user interface may comprise one or more buttons, one or more sliders, one or more switches, one or more interface wheels, one or more capacitive sensors, and/or the like. In various embodiments, the user interface enables a user to select between an “on” state (e.g., a single “on” state at a non-selectable power level) and an “off” state. The user interface may, in certain embodiments, enable selection between a plurality of “on” states corresponding to various output modes (e.g., a red light mode or a white light mode) and/or various output power levels (e.g., various brightness levels emitted by the one or more light sources65of the second light emitting component14of the example lighting device10). A single button user interface may allow users to cycle between an “off” state and various “on” states with sequential activations of the button. For example, pressing the button once turns the light on to a first lighting mode (e.g., a red light mode), pressing the button again changes the light to a second lighting mode (e.g., a white light mode) at a first brightness level, and pressing the button a third time changes the light to a second brightness level within the second lighting mode, and pressing the button yet again cycles the light back to the off state. Other example embodiments comprise only a single lighting mode, and therefore pressing the user-interface button multiple times may cycle the light through various brightness levels within a single lighting mode (e.g., within a white light mode).

The body60may be configured (e.g., sized, dimensioned, or the like) to nest within the open first end21of the housing20of the first light emitting component12such that when the body is inserted into the housing20of the first light emitting component12, the second end of the body60is parallel with an edge surrounding the open first end21of the housing20. In certain embodiments, the body60nests within the open first end21of the housing20with a gasket or other component that seals the body60into the open first end21against water intrusion. Moreover, the body60nests within the open first end21to define a frictional engagement therebetween, such that the second light emitting component14remains coupled with the first light emitting component12unless a user physically decouples the components of the lighting device10. In certain embodiments, the body60may have a shape that is the same as the shape of the housing20of the first light emitting component12to enable the second end of the body60to be parallel with an edge surrounding the open first end21of the housing20. For example, in the illustrated example embodiments, the body60and the housing20may both have a square shape. However, it should be understood that in various other embodiments, the body60and housing20may have a variety of shapes (circle, oval, rectangular, polygonal, and/or the like), and the shape of the body60and the housing20may be different.

In certain embodiments, the second light emitting component14comprises a second power source (e.g., batteries79), which may be embodied as an onboard power source comprising one or more batteries (e.g., replaceable primary batteries or rechargeable secondary batteries (integrated within the second light emitting component or replaceable secondary batteries)) or other electricity storage devices. For example, in certain embodiments, the second light emitting component14may comprise an onboard power source capable of, with the light sources, generating a light output of at least about 100 lumens. As a specific example, the lighting device may comprise an onboard power source embodied as 2AA batteries. The power source (not shown) provides power to the one or more second light sources65configured for generating a light output. In certain embodiments, the body60comprises one or more electrical contacts (not shown) that is in electrical communication with one or more electrical contacts (not shown) of the housing20of the first light emitting component12to enable the power source of the body to be charged from the housing20.

CONCLUSION
