Light emitting devices may comprise light emitting diodes. Light emitting diodes (also referred to herein as LEDs) are semiconductor devices that emit light when an electric current is passed through them. The light is produced when particles that carry the electric current (i.e., electrons and holes) combine together with the semiconductor material of the semiconductor devices. LEDs are described as solid-state devices, which distinguishes them from other lighting technologies that use heated filaments or gas discharge as lighting sources (e.g., incandescent, tungsten halogen lamps; fluorescent lamps).
LEDs are widely used in lighting applications for residential and commercial structures. LEDs utilizing solar power are likewise widely used in lighting applications for residential and commercial structures. One such application is solar landscape lighting.
However, conventional solar landscape lights provide either a downlight effect for pathway lighting or an accent effect for decorative lighting. Deficiencies regarding but not limited to suitable materials, power supply, and control methods have imposed this limitation that conventional solar landscape lights can only provide either pathway lighting or decorative lighting, but not both. There is therefore a need for a solar landscape lighting device providing both pathway lighting and decorative lighting.
Through applied effort, ingenuity, and innovation many deficiencies of such systems have been solved by developing solutions that are in accordance with the embodiments of the present invention, many examples of which are described in detail herein.

This Summary does not attempt to completely signify any particular innovation, embodiment, or example as it can be used in commerce. Additionally, this Summary is not intended to signify essential elements of an innovation, embodiment or example or to limit the scope of the subject matter of this disclosure.
The innovations, embodiments, and/or examples found within this disclosure are not all-inclusive, but rather describe the basic significance of the subject matter. Accordingly, one use of this Summary is as a prelude to a Detailed Description presented later.
The following Detailed Description, Figures, and appended Claims signify the nature and advantages of the innovations, embodiments and/or examples of the claimed inventions. All the Figures signify innovations, embodiments, and/or examples of the claimed inventions for purposes of illustration only and do not limit the scope of the claimed inventions. Such Figures are not necessarily drawn to scale and are part of the Disclosure.
In the Figures, similar components or features may have the same, or similar, reference signs in the form of labels (such as alphanumeric symbols, e.g., reference numerals), and may signify similar or equivalent functionality. Further, various components of the same type may be distinguished by a second or third label that distinguishes among the similar components (e.g., 1A and 1B may refer to components of the same type). If only the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label. A brief description of the Figures is below.
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.
Embodiments of the present disclosure provide a landscape lighting device configured for dynamic functionality. That is, a landscape lighting device according to embodiments of the present disclosure is configured to provide both pathway lighting and decorative lighting. An example landscape lighting device according to embodiments of the present disclosure may be selectively operable to provide either pathway lighting or decorative lighting at any one time, in any particular operation session. An example landscape lighting device according to embodiments of the present disclosure may be configured for user selection of a plurality of dynamic LED functionalities.
Landscape lighting devices according to embodiments of the present disclosure employ a novel solar panel configuration. Embodiments of a landscape lighting device as described herein are therefore enabled to collect, store and utilize solar power to achieve both pathway lighting and decorative lighting.
Conventional solar landscape lights lack suitable configuration of the solar panel(s) to achieve the user functionality choices including both pathway lighting and decorative lighting as well as dynamic LED functionality. Conventional solar landscape lights configure solar panels at the top of the light fixtures. Consequently, conventional solar landscape lights would further require the use of a rechargeable battery, an accompanying compartment to house the rechargeable battery, and a control method to achieve both pathway lighting and decorative lighting. Such a configuration is not feasible in conventional designs, because a rechargeable battery would need to be housed at the top of the light fixture, thereby inhibiting light emission. Conventional solar landscape lights therefore suffer deficiencies regarding power supply, power consumption, and methods to control the same.
Landscape lighting devices according embodiments of the present disclosure overcome these deficiencies of conventional solar landscape lights by employing a novel configuration of a solar panel. In various embodiments of landscape lighting devices herein, a landscape lighting device may be configured such that solar energy is collected at the lighting device housing bottom face, within the lighting device housing interior. Landscape lighting devices of various embodiments may therefore employ a rechargeable battery(s) in electrical communication with the solar panels, enabling the configuration of a switch for selecting both pathway lighting and decorative lighting. The lighting device housing of various embodiments comprises material conducive for the collection and storage of solar power within the lighting device housing interior. For example, landscape lighting devices according to embodiments of the present disclosure may employ clear glass to allow sunlight into and through the lighting device housing interior to the bottom of the fixture. Absent the novel configuration of the solar panels as described herein, the use of a rechargeable battery is not possible. Hence, sufficient power to provide both pathway lighting and decorative lighting would not be possible.
Alternate embodiments of landscape lighting devices described herein may nonetheless be configured to collect and store solar power at the lighting device housing top face, while providing user functionality choices including either or both pathway lighting and decorative lighting as well as dynamic LED functionality. Landscape lighting devices according to alternate embodiments described herein thus employ solar panels both at the top of the lighting fixture and within its interior, as described above. Landscape lighting devices according to these alternate embodiments therefore overcome the deficiencies of conventional solar landscape lights that require that the solar panel(s) remain at the top of the fixture.
Alternatively, the lighting device housing panes 102A″ may comprise a suitably translucent material such as frosted glass. As shown, the lighting device housing frame 102A′ and lighting device housing panes 102A″ may in combination define a profile that is substantially the outer surface a right square prism, being oriented along a longitudinal axis taken through the center of its square cross-section. The lighting device housing interior may thus define the void enclosed by the six faces of the right square prism. Alternatively, the lighting device housing may define a profile of any regular or irregular geometric shape suitable to configure an interior and exterior therefrom (e.g., cylinder, sphere, pentagon, etc.). The lighting device housing interior of embodiments is configured to house a plurality of landscape lighting LEDs 104A, 104B therein.
A lighting device bottom face may comprise a first bottom face portion 108A, which is substantially square shaped and defines a square shaped central recess configured to receive a planar portion therein. The first bottom face portion 108A may define a recessed ledge about its perimeter so as to be mechanically coupled to the lighting device housing 102. That is, the lighting device housing may sit atop the first bottom face portion 108A so as to engage the recessed ledge of the first bottom face portion 108A.
A lighting device bottom face may comprise a second bottom face portion 108B that is substantially square in cross section and has a raised planar portion on a dorsal surface. The raised planar portion may be configured to receive a solar panel 302A and to couple to the square shaped central recess of the first bottom face portion 108A. A ventral surface of the second bottom face portion 108B may define a square shaped recess configured to house a rechargeable battery therein. By thus configuring the square shaped recess of the second bottom face portion 108B as a rechargeable battery compartment, a lighting device mode switch 108C may be configured within the lighting device bottom face. The second bottom face portion 108B may comprise voids (e.g., bores) configured to receive four fastening means 108F (e.g., screw caps) at each of the four corners of a ventral surface.
A lighting device mode switch 108C may be substantially square in cross section and have a toggle switch extending radially from the center of a ventral surface. A toggle switch cover 108D may be configured in a suitable shape to encase the toggle switch of the lighting device mode switch 108C, and to enhance the user interface of the toggle switch. The lighting device mode switch 108C may be configured to couple with the second bottom face portion 108B. The lighting device mode switch 108C may be configured in electrical communication with the landscape lighting LEDs 104A, 104B, so as to initiate and change the operating mode of a landscape lighting device 100 according to embodiments of the present disclosure. Hence, by manipulation of the toggle switch of the lighting device mode switch 108C, a user may turn on/off a landscape lighting device 100, and initiate one or more of pathway lighting, decorative lighting or dynamic LED functionality. For example, a user may toggle the toggle switch of the landscape lighting device a first time in a first manner to turn on a landscape lighting device 100 from an off mode. A user may then toggle the toggle switch again in the first manner to initiate a first landscape lighting device operation mode. For example, a first landscape lighting device operation mode may be pathway lighting. A second landscape lighting device operation mode (e.g., decorative lighting or dynamic LED functionality) may be initiated by subsequent toggles of the toggle switch in the first manner. When a landscape lighting device is operated in a dynamic LED functionality mode, a user may toggle the toggle switch in a second manner to select between dynamic LED functionalities. For example, a first toggle of the toggle switch in a second manner may initiate a multi-color lighting effect. A second toggle of the toggle switch in a second predetermined manner may then initiate a solid white lighting effect. Subsequent toggling of the toggle switch in the second manner may thus cycle through dynamic LED functionalities. A final toggle of the toggle switch in the first manner may then return the landscape lighting device 100 to an off mode.
A lighting device bottom face may comprise a third bottom face portion 108E. The third bottom face portion 108E may be substantially square in cross section and have a toggle switch receptor that is a substantially rectangular void configured to receive the toggle switch of the lighting device mode switch 108C and the accompanying toggle switch cover 108D at the center of a ventral face. The third bottom face portion 108E may define four circular voids arranged in an equilateral perimeter about the toggle switch receptor that are configured to receive four landscape pathway lighting LEDs 104A. The third bottom face portion 108E may define four voids at its periphery that are configured to receive fastening means 108F so as to couple the third bottom face portion 108E to the second bottom face portion 108B. Thus configured, the second bottom face portion 108B and third bottom face portion 108E may simultaneously encase the lighting device mode switch 108C, the toggle switch cover 108D, and landscape pathway lighting LEDs 104A and couple, via fastening means 108F, to the landscape decorative lighting LEDs 104B.
A lighting device housing top face may comprise a first top face component 110A and a second top face component 110B that are mechanically coupled to one another. The first top face component 110A may be substantially square in cross section with recessed ledges configured to engage the second top face component contouring its perimeter and may define on a ventral surface a central void (e.g., a bore) configured to receive fastening means 110C (e.g., a bolt) for coupling to the second top face component 110B. The fastening means 110C may receive an endcap (e.g., a screwcap) 110C′ at a proximate end for securing the first top face component 110A to the second top face component 110B. The fastening means 110C may receive, for example, a washer 110C″ and nut 110C′″ at a distal end for securing the first top face component 110A to the second top face component 110B. The first top face component 110A may define on a ventral surface peripheral voids configured to receive the distal ends 104B′ of the landscape decorative lighting LEDs 104B. Washers 110D may be configured to secure the distal ends 104B′ of the landscape decorative lighting LEDs 104B to the first top face component 110A.
The second top face component 110B may define a substantially pyramidal profile, having a substantially square cross section. The second top face component 110B may define an inner void configured to house lighting device components therein, and have recesses configured to engage the recessed ledges of the first top face component 110A contouring an inner surface. The second top face component 110B may define a central void configured to receive the fastening means 110C in order to couple a lighting device installation loop 112A and installation loop washer 112B to the second top face component 110B. The lighting device installation loop 112A may comprise a substantially ring-shaped body configured to couple to the hook portion of the lighting device installation arm by inserting the hook portion of the lighting device installation arm through the ring of the lighting device installation loop 112A. A battery 116 may be housed within the inner void of the second top face component 110B. The battery 116 may be, for example, a dry cell such as Alkaline, Nickel oxyhydroxide, Zinc chloride or the like. Alternatively, the battery 116 may be a rechargeable battery such as NiCd, NiMH, Lead Acid, Li-ion, Li-ion polymer, Aluminum-ion, Magnesium-ion, or the like. The battery 116 may be of any suitable size, e.g., 4.5V, D, C, AA, AAA, AAAA, 9-volt, etc. The battery 116 may comprise, as illustrated in
In embodiments, the landscape lighting device 100 comprises a lighting device installation arm 106. The lighting device installation arm 106 of various embodiments is mechanically coupled to the lighting device housing 102. In various embodiments, the lighting device installation arm 106 is configured for coupling the lighting device installation arm 106 to an environment. For example, as shown in
A lighting device installation arm 106 may comprise a second installation arm portion 106C. The second installation arm portion 106C may be cylindrical in profile, defining inner voids at proximal and distal ends configured to longitudinally receive fasteners 106B therein. Thus, the first installation arm portion 106A may be mechanically coupled, via the fasteners 106B, to the second installation arm portion 106C.
A lighting device installation arm 106 may comprise a third installation arm portion 106D that is mechanically coupled to the second installation arm portion 106C. The third installation arm portion 106D may comprise a cylindrical portion having screw threads configured radially on a portion of its outer surface, and a hook-shaped projection extending radially from the unthreaded cylindrical portion. The unthreaded cylindrical portion of the third installation arm portion 106D may define an inner void such that the third installation arm portion 106D may be mechanically coupled, by a fastener 106B and via the inner void, to the second installation arm portion 106C.
A lighting device installation arm may comprise a fourth installation arm portion 106E. The fourth installation arm portion 106E may define a profile that is substantially arrow shaped, and have a cylindrical portion defining an inner void configured at a cranial end. The cylindrical portion of the fourth installation arm portion 106E may be configured to couple with the threaded outer surface of the cylindrical portion of the third installation arm portion 106D. Thus configured, a lighting device installation arm may act as a ground stake to couple a landscape lighting device 100 to an environment. However, the lighting device installation arm 106 may be any other suitable installation means for coupling a landscape lighting device 100 with an environment, including but not limited to tree mounts, flag pole mounts, wall mounts or the like.
In certain embodiments, the landscape lighting device 100 comprises a plurality of landscape lighting LEDs 104A, 104B disposed within the lighting device housing interior.

Landscape decorative lighting LEDs 104B may be any suitable LED type configured to provide a decorative aesthetic, including pendants, string lights, fairy lights or the like. For example, as shown in
The exemplary landscape lighting device 100 of various embodiments comprises driver circuitry 206 disposed on and/or electrically and mechanically coupled with one or more of the first circuit board side 202A or the second circuit board side. The driver circuitry 206 of various embodiments may be electrically coupled with the plurality of leads/traces 204 of the circuit board 202. The driver circuitry 206 of an exemplary landscape lighting device 100 may be any suitable driver circuitry 206, including but not limited to, linear LED driver circuitry, linear regulator, specialized linear LED controller, switch mode LED driver circuitry and/or the like.
Driver circuitry 206 is configured to enable dynamic functionality (e.g., a single color lighting effect, a multi-color lighting effect, a solid white lighting effect, a solid single color lighting effect, a solid multi-color lighting effect, a flame lighting effect, a flashing lighting effect, a twinkling lighting effect, a shimmering lighting effect, a chasing lighting effect, a sequencing lighting effect, or a color cycling lighting effect). An appropriate driver circuitry 206 may be, for example, a 16-channel LED driver. Such an example driver circuitry 206 may be configured such that each channel is individually adjustable. For example, an example driver circuitry 206 may be configured with DOT correction and grayscale PWM control.
As shown in
The lighting device housing panes 102A″ of various embodiments comprise glass, acrylic, polycarbonate, an optically transparent material, or other material conducive to the transmission of light and solar energy. This further facilitates collecting and storing of solar power occurring within the lighting device housing interior 102B.

Landscape decorative lighting LEDs 104B of a landscape lighting device 200 are configured for dynamic LED functionality. For example, landscape decorative LEDs 104B may be configured to enable dynamic selection between a solid white lighting effect and a flame lighting effect. Thus, when enabled as a flame lighting effect, landscape decorative lighting LEDs 104B may be driven in a rising and falling pattern thereby imitating a flame aesthetic. Such a flame lighting effect may be employed to provide an appropriate ambiance. When enabled to produce a solid white lighting effect, landscape decorative lighting LEDs 104B may glow with a soft white color temperature. Landscape pathway lighting LEDs 104A may be any suitable LED type configured for pathway lighting including fixed downlights, gimble downlights, can lights, pot lights or the like.
The lighting device installation arm 106 of various embodiments may comprise a single component, as shown in
