[0012] This invention relates to a dual-power source light source device. More specifically, this invention relates to a flashlight, lantern, or other light source having multiple power sources. Typically, a dual-power source light source may include a first power source and a second power source powering the light source. In one exemplary embodiment, the first power source is a rechargeable battery, and the second power source is one or more alkaline or other non-rechargeable batteries. The user operating the light source can switch between the first and second power sources to select a desired power source, or can use both power sources.

[0013] In some exemplary embodiments, a rechargeable battery is built into the light source, and the alkaline battery can be removed and replaced by the user. In some exemplary embodiments, the dual-power light source may include a dual-power battery case that holds and provides two different types of power. For example, the dual-power battery case may hold a first power source, such as a rechargeable battery, in a permanently or semi-permanently sealed portion; the dual-power battery case may hold a second power source, such as a non-rechargeable battery, in an open or unsealed portion of the dual-power battery case. The dual-power battery case can provide separate power outputs for the two different power sources.

[0014] Figure 1 A side view of a dual-power lighting device 100 and a detailed view of an exemplary dual-power selector 103 are shown. The dual-power lighting device 100 may also include a removable base cover 109 that allows for maintenance of the dual power supply of the device.

[0015] The dual-power supply selector 103 of the dual-power supply lighting device 100 provides the user with the ability to select between two or more power sources. The power sources of the dual-power supply lighting device 100 may include alkaline, replaceable or non-rechargeable power sources, as well as rechargeable power sources.

[0016] The dual power selector 103 may provide one or more buttons, sliders, toggle switches, or other types of physical selection components that a user can interact with to select between two or more power sources or control the mode of the dual power lighting device 100. The dual power selector 103 may include two power selector components or buttons. In other embodiments, the dual power selector 103 may include a mechanism that physically moves to mechanically engage contacts for selecting between two or more power sources.

[0017] In some embodiments, the power selector may include a rechargeable power selection component 112 and an alkaline or replaceable power selection component 115. The two power selectors of the dual power selector 103 may be provided using integrated two-part external buttons (e.g., a rocker or membrane), or alternatively, using two separate physical buttons. In some embodiments, the underlying electronics may include two different switches or a multi-pole switch, among other options.

[0018] The dual power selector 103 may also provide one or more lamps or illumination indicators to indicate the power selection status. The power selection status can indicate which power source is selected and used for the dual power lighting device 100. In this embodiment, the dual power selector 103 displays a separate power status indicator for each power source used in the device. In other embodiments, a single power status indicator may vary in color, hue, pattern, icon, cutout, or other features to indicate the selected power source.

[0019] The power status indicator can also display the charge level or power level of the associated power source. In some embodiments, only the power level of the selected power source is displayed. The power status indicator can also indicate whether the power source is below a threshold, whether the power source is fully charged or overcharged, whether the power source is currently charging, etc.

[0020] Specific charge levels can also be provided. A specific charge level can refer to a portion or percentage of the total charge. The charge level, power type selection, and other information discussed for the power status indicator can be displayed as the number of lights, the length (distance) of light illuminated across the bar, the color of the status lights, predetermined flashing and / or intensity fluctuation patterns, etc.

[0021] For example, the first status light color, predetermined flashing and / or intensity fluctuation pattern can indicate a low power level that has exceeded a predetermined threshold voltage or other threshold. The second status light color, predetermined flashing and / or intensity fluctuation pattern can indicate a high or fully charged power level that has exceeded a predetermined threshold. The third status light color, predetermined flashing and / or intensity fluctuation pattern can indicate that the power supply is charging. Typically, the status indicator can provide multiple charging states of the power supply, such as charging, charged, low power, etc. Non-rechargeable power supplies will not utilize the "charging" indication of the status indicator because they will not be charged within the device.

[0022] The status indicators shown include a rechargeable power supply indicator 118 and an alkaline or replaceable power supply indicator 121. The rechargeable power supply indicator 118 provides an indication that a rechargeable power supply has been selected and is in use, indicating whether it is lit or not. The replaceable power supply indicator 121 provides an indication that a replaceable power supply has been selected and is in use, indicating whether it is lit or not.

[0023] The dual power selector 103 (e.g., rechargeable power selector 112 and replaceable power selector 115) can also be used to select the illumination mode of the main light source of the dual power lighting device 100. Among the various modes of the selected power source, the light source can be set to flash, pulse, or strobe; can be set to provide a constant light source typical of a flashlight; can be set to a specific color; can be set to change color continuously or periodically; can be set to various illumination intensities, and other understandable operations. In some embodiments, an illumination status indicator can indicate the selected mode.

[0024] Figure 2 A side view of a dual-power lighting device 100 is shown. This view shows the dual-power lighting device 100 relative to... Figure 1 On the opposite side. In this view, the base cover 109 can be seen at the bottom, and the charging port 203 can be seen on the handle.

[0025] Although shown on the handle near the connection to the lighting head of the dual-power lighting device 100, the charging port 203 may alternatively be located closer to the base cover 109. The charging port 203 may also be integrated into the base cover 109 or the lighting head assembly. The charging port 203 may include a tab-like cover that can serve as a dust protector. In some embodiments, the cover may also provide waterproof or water-resistant protection for the charging port 203. The cover may include a push-fit, snap-fit, latch, or other closing mechanism.

[0026] The charging port 203 can charge a rechargeable power source (such as a battery permanently installed in the body of the dual power lighting device 100, or a battery sealed in the dual power box of the dual power lighting device 100). Figures 3-6 An embodiment of a dual-power supply box is shown. In the case of a rechargeable power supply installed within the dual-power lighting device 100, a replaceable, alkaline, or non-rechargeable power supply can be directly inserted into the dual-power lighting device 100, for example, inserted into the hatch of the body once opened, or inserted into the bottom of the device once the base cover 109 is removed. However, a replaceable, alkaline, or non-rechargeable power supply can also be inserted into a single-power supply box.

[0027] Figure 3 A side view and a cross-section AA of the dual-power lighting device 100 are shown. Cross-section AA shows the internal components of the dual-power lighting device 100. Cross-section AA represents a top-to-bottom slice of the dual-power lighting device 100, passing through the head 303, body 304, and base cover 109. Cross-section AA prominently passes through the dual-power selector 103, charging port 203, and power status indicators 118 and 121.

[0028] The dual-power lighting device 100 may include a head 303. The head 303 may be a durable external component containing multiple light source elements. The head 303 may include one or more of metal, plastic, rubber, and other materials selected for durability. The head 303 may include a light source housing 306.

[0029] The light source housing 306 may be a rigid internal component inside the head 303. The light source housing 306 may include one or more of metal, plastic and other materials selected to provide a rigid housing for the exterior of the light source 309, the head 303, the reflector 312, the lens 315 and the lens ring 318 and other components.

[0030] In various embodiments, the light source 309 may include a light-emitting diode (LED) lamp, an incandescent bulb, a chip-on-board (COB) LED, or other types of light source. The light source 309 may be connected to the chip, circuit board, or other light source circuit of the dual-power lighting device 100. The light source circuit may be connected to both power sources of the dual-power lighting device 100, allowing the light source 309 to be powered by either power source.

[0031] Reflector 312 may include a parabolic, conical, or other type of reflector that provides a desired light distribution from light source 309 to lens 315. The reflector may also provide an appropriate spacing between light source 309 and lens 315. Lens 315 may include glass, polycarbonate, plastic, or other types of transparent or translucent materials.

[0032] Lens 315 can provide the desired light projection from the dual-power lighting device 100. In some cases, the dual-power lighting device 100 can be adjusted by pulling, twisting, or otherwise manipulating the head 303, body 304, base cover 109, or other beam adjustment buttons or sliding parts. Beam adjustment can move the lens 315 toward and away from the light source 309, and move the light source 309 toward and away from the lens 315. This can make the beam from the dual-power lighting device 100 wider and more diffuse, or narrower and more focused.

[0033] The lens ring 318 can hold the lens 315 in the head 303. The head 303 may include a ridge or other component that can hold the lens ring 318 against the lens 315. Alternatively, the lens ring 318 can be held by friction engagement, physical fasteners (such as screws), or chemical fasteners (such as glue or epoxy resin).

[0034] The dual-power lighting device 100 may further include a chip, circuit board, or other main circuit component 320, which may also be referred to as a switching circuit. The main circuit component 320 may include power switches 321 and 324, respectively corresponding to power selection components 112 and 115. The dual-power lighting device 100 may also include an electronic housing or other housing 333 within the body 304. The housing 333 may accommodate the main circuit component 320, the switches, and other components shown within the body 304 of the dual-power lighting device 100.

[0035] The "rechargeable power supply" switch 321 can be used in conjunction with the rechargeable power supply selection component 112. When a user presses, slides, or otherwise manipulates the rechargeable power supply selection component 112, if the dual-power lighting device 100 is off, or if the replaceable power supply 351 is currently in use, the rechargeable power supply switch 321 can provide a switching action to the main circuit component 320 to enable or switch the power supply to the rechargeable power supply 348. If the rechargeable power supply 348 is in use, further pressing or manipulating the rechargeable power supply selection component 112 can cause the rechargeable power supply switch 321 to change the lighting mode of the dual-power lighting device 100 and / or turn off the dual-power lighting device 100. The switching device of the dual-power lighting device 100 may include one or more power selection components or buttons and one or more electrical switching components.

[0036] The "alkaline or replaceable power" switch 324 can be used in conjunction with the replaceable power selection component 115. When the user presses, slides, or otherwise manipulates the replaceable power selection component 115, if the dual-power lighting device 100 is off, or if the rechargeable power supply 348 is currently in use, the replaceable power switch 324 can provide a switching action to the main circuit component 320 to enable or switch the power supply to the replaceable power supply 351. If the replaceable power supply 351 is in use, further pressing or manipulating the replaceable power selection component 115 can cause the replaceable power switch 324 to change the lighting mode of the dual-power lighting device 100 and / or turn off the dual-power lighting device 100.

[0037] The rechargeable power supply 348 and the replaceable power supply 351 can be detachably connected to the main circuit component 320 using spring pins or other types of contacts 352. Although one of the multiple contacts 352 is shown, the other contacts may be on a line or on another plane or cross-section. There may be three or more contacts 352, including one (or more) negative or ground connection and two power connections, with one power connection each for the rechargeable power supply 348 and the replaceable power supply 351. While three or more contacts 352 may be located on top of the dual power supply housing 355 to reduce wiring in the body 304, other embodiments may include contacts 352 located at the bottom of the dual power supply housing 355, having wiring, traces, or other electronic circuit connections to the main circuit component 320 in the body 304.

[0038] It is worth noting that the dual power supply box 355 can be designed to align within the body 304 of the dual power supply lighting device 100, thus limiting it to a single desired alignment. This alignment feature prevents the unrechargeable (or non-replaceable) battery from being accidentally charged when an external power source is connected to the charging port 203. This safety mechanism, along with other safety mechanisms, also prevents the user from short-circuiting the two different power sources of the dual power supply box 355. The alignment feature of the dual power supply box 355 will be referenced... Figures 4-6 Further discussion.

[0039] Charging port 203 can be connected to main circuit component 320, which provides connection to rechargeable power supply 348 via an appropriate subset of contacts 352. Alternatively, charging port 203 can be connected to charging circuitry 336, which connects to contacts 352 of rechargeable power supply 348 or another set of contacts. Charging port 203 may include a standardized or dedicated power connector. Standardized power connectors may include cylindrical plug connectors, Universal Serial Bus (USB) type connectors, and other connectors.

[0040] The USB connector may include USB-A, USB-B, USB-C, Mini USB-A, Mini USB-B, Micro USB-A, Micro USB-B, and other USB connectors. While the charging port 203 may be located on the body of the dual-power lighting device 100, it may alternatively be located on the side of the base cover 109, or on the bottom of the dual-power lighting device 100 opposite the lens 315 and the light source 309.

[0041] Figure 4 A bottom perspective view and a detailed view of the dual-power lighting device 100 and its dual-power box 355 are shown. In this view, the base cover 109 has been removed from the bottom of the body 304. The dual-power box 355 has been removed from inside the body 304. Figure 4 Includes a detailed view of alignment system 403.

[0042] The alignment system 403 may include one or more alignment notches 406 that mate with one or more corresponding alignment tabs 412 (including alignment tabs 412a-412c) and one or more alignment tracks 415. The alignment tabs 412 and alignment tracks 415 may be considered as alignment components of the housing or body of the dual-power lighting device 100.

[0043] The alignment notch 406 may include a notch in the bottom side of the body 304, or a notch in the bottom side of a plug-in within the body 304. The bottommost surface of the body 304 or the plug-in may be circular, n-sided (a polygon with n sides), or other shapes from which the alignment notch 406 is cut. The alignment notch 406 allows the dual power box 355 to be fully inserted into the body 304 in a single orientation and prevents the dual power box 355 from being fully inserted into the body 304 in any other orientation. The alignment system 403 thereby prevents the power contacts of the dual power box 355 from contacting the corresponding contacts unless the dual power box 355 is correctly aligned. This ensures that the non-rechargeable battery is not accidentally charged and forces all power contacts of the dual power box 355 to be correctly aligned with the corresponding power contacts within the dual power lighting device 100.

[0044] In this embodiment, there are two alignment notches 406, but any number of alignment notches 406 can be used. The two alignment notches 406 can have different sizes. Different sized notches prevent incorrect orientation because the larger of the alignment lugs 412 cannot fit into the smaller of the alignment notches 406.

[0045] Alignment lugs 412 may be present at one or both ends of the dual power box 355. In the illustrated embodiment, alignment lugs 412 include two alignment lugs 412a and 412b on the replaceable, alkaline, or non-rechargeable side of the dual power box 355. Alignment lugs 412 may also include two alignment lugs on the rechargeable side of the dual power box 355, but only alignment lug 412c is visible from the illustrated angle. When alignment lugs 412 are present at both ends of the dual power box 355, alignment rails 415 may be used. Alignment lug 412a may be located at the top or insertion end of the dual power box 355. Alignment lugs 412b and 412c may be located at the bottom or outer end of the dual power box 355. In some embodiments, the top alignment lug 412 may be smaller than the bottom alignment lug 412. Alignment rails 415 may be sized to accept or fit at least one size and shape of the top or insertion end alignment lug 412.

[0046] In some embodiments, the alignment track 415 may be too small to accommodate the bottom alignment tab 412. This prevents reverse insertion of the dual power box 355. However, the alignment notch 406 is sized to accommodate the bottom alignment tab 412. In some implementations, the alignment track 415 may be omitted. In this embodiment, the alignment tab 412 may be present at the bottom of the dual power box 355 and may be omitted or absent at the top. While for convenience, some alignment tabs 412 may be referred to as non-rechargeable side and rechargeable side alignment tabs 412, the alignment tab 412 can be located in any orientation on the dual power box 355.

[0047] Although the alignment lug 412 or top alignment lug 412a inserted into the alignment track 415 is shown aligned with the bottom alignment lug 412b, other embodiments may have a bottom alignment lug 412 offset relative to the top alignment lug 412. In this embodiment, the alignment notch 406 may be offset from the alignment track 415 to accommodate the offset bottom alignment lug 412.

[0048] The dual power supply box 355 is shown with non-rechargeable, alkaline, or replaceable sides. As can be seen from this view, non-rechargeable, alkaline, or replaceable batteries can be inserted into corresponding openings in the dual power supply box 355. Although not shown, the rechargeable batteries in the dual power supply box 355 can be covered with a non-removable cover, such that the rechargeable batteries are embedded or sealed therein. In some embodiments, a removable cover can be used to seal the rechargeable batteries into the dual power supply box 355. A non-removable cover can refer to a cover glued in place, a cover held in place using separate physical fasteners, or a cover held in place using integrated fasteners (e.g., clips that retract once in place).

[0049] In some embodiments, the dual power supply box 355 may include a solid plastic housing into which a rechargeable battery is inserted during assembly of the dual power supply box 355. Once assembled, the embedded rechargeable battery may not be removable without damaging or disassembling the dual power supply box 355. In any case, sealing or embedding the rechargeable battery prevents accidental removal of the rechargeable battery when the user replaces alkaline or other non-rechargeable batteries.

[0050] Figure 5 This is a bottom view of the dual-power lighting device 100 with the base cover 109 removed. The view shows a set of three contacts 352. In other embodiments, other numbers of contacts 352 may be used, such as four contacts 352. The set of three contacts 352 may include a negative or ground connection and two power connections, one for a rechargeable power supply 348 and one for a replaceable power supply 351.

[0051] Although the contacts 352 are aligned in a linear shape in this embodiment, if there are three contacts, the contacts 352 may alternatively form a triangular shape, or if there are four contacts, the contacts 352 may form a rectangle or another quadrilateral shape. In any case, the alignment notch 406 and the alignment track 415 ensure that the dual power supply box 355 (not shown) can only be inserted such that the rechargeable power contacts 352 of the dual power supply lighting device 100 mate with the rechargeable power contacts of the dual power supply box 355, and the non-rechargeable power contacts 352 of the dual power supply lighting device 100 mate with the non-rechargeable power contacts of the dual power supply box 355.

[0052] Figure 6 Various views of the dual power supply box 355 of the dual power supply lighting device 100 are shown. These views include top view, bottom view, front view, side view, rear view, and sectional view.

[0053] From the top view, a set of box contacts 703 of the dual-power box 355 is shown. The box contacts 703 can be arranged to mate with the contacts 352 of the dual-power lighting device 100. Although the box contacts 703 are linear in shape in this embodiment, if there are three box contacts 703, they can alternatively form a triangular shape, or if there are four box contacts 703, they can form a rectangular or other quadrilateral shape. In any case, the box contacts 703 can mate and pair with the contacts 352 of the dual-power lighting device 100.

[0054] From the bottom view of the dual power supply box 355, bottom alignment lugs 412b and 412c are shown. Bottom alignment lug 412b can be aligned with and fitted into the alignment notch 406 of the dual power supply lighting device 100. In some embodiments, bottom alignment lug 412b can also be aligned with and fitted into the alignment track 415 of the dual power supply lighting device 100.

[0055] The front view of the dual power supply box 355 shows a non-rechargeable, replaceable, or alkaline battery 706. The battery 706 can be inserted into an open battery slot in the dual power supply box 355. The front view of the dual power supply box 355 also shows the lines taken in cross-sectional view BB.

[0056] In the cross-sectional view BB of the dual power supply box 355, non-rechargeable, replaceable, or alkaline batteries 706 are shown in black, while rechargeable batteries or battery packs 709 are shown in crosshairs. This view shows that batteries 706 are inserted into open battery slots. Batteries 706 can be easily removed from these open battery slots. When rechargeable batteries or battery packs 709 are sealed within the dual power supply box 355, the user can quickly identify that batteries 706 are usable and easily removed. Because rechargeable batteries 709 are sealed or embedded within the dual power supply box 355, or sealed or embedded within the housing or body of the dual power lighting device 100, they can be considered non-replaceable even if the box is removable.

[0057] Even with a removable panel (which can be removed to maintain the rechargeable battery 709), the rechargeable battery 709 is sealed within the dual power box 355 and is more difficult to remove. This prevents accidental removal of the rechargeable battery 709 when the non-rechargeable, replaceable, or alkaline battery 706 is ready to be replaced.

[0058] From the side view of the dual power supply box 355, a non-rechargeable, replaceable, or alkaline battery 706 is shown on the left side of the image, and a casing or cover shows the area where the rechargeable battery 709 is encapsulated. This view shows that the battery 706 is inserted into an open battery slot. The battery 706 can be easily removed from these open battery slots. When the rechargeable battery or battery pack 709 is sealed within the dual power supply box 355, the user can quickly identify that the battery 706 is usable and can be easily removed.

[0059] The rear view of the dual power supply box 355 shows a housing or cover containing the rechargeable battery 709. The housing or cover prevents accidental removal of the rechargeable battery 709 when the non-rechargeable, replaceable, or alkaline battery 706 is ready to be replaced.

[0060] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship between one component of an icon and another, their use is merely for convenience, such as the orientation according to the embodiments described in the accompanying drawings. It is understood that if the device is inverted, a component described as "upper" will become a "lower" component. When one structure is "on" or "on another structure," this may mean that one structure is integrally formed on the other structure, or that one structure is "directly" arranged on the other structure, or that one structure is "indirectly" arranged on the other structure through the other structure.

[0061] The terms “a,” “an,” “the,” and “the” are used to indicate the presence of one or more elements, parts, etc. The terms “comprising” and “having” are used to indicate open inclusion and refer to the possibility of other elements, parts, etc., besides those listed. The terms “first” and “second” are used only as labels and are not intended to limit the number of objects. The term “substantially” can describe an approximate fit, value, direction, orientation, or other parameter within a predetermined tolerance (e.g., 1%, 2%, 3%, 4%, 5%, or other predetermined tolerances).

[0062] It should be emphasized that the above-described embodiments of this disclosure are merely possible implementations set forth for the purpose of clearly understanding the principles of this disclosure. While features may be described in conjunction with specific drawings, these features may also be combined with features in other drawings. Many variations and modifications can be made to the above-described embodiments without substantially departing from the spirit and principles of this disclosure. All such modifications and variations are intended to be included within the scope of this disclosure and are protected by the appended claims.
