[0047] Turning now to the accompanying drawings, low voltage LED filament array bulbs are shown, as well as devices using low voltage LED filament bulbs. Despite being invented for more than a century, Edison-style filament bulbs remain a popular appearance. However, incandescent filaments require a large amount of energy to operate. Traditional LED filament arrays are made of many LEDs arranged linearly and wired in series, and are typically coated with a yellow phosphor coating of a silicone adhesive material. Low voltage LED filament arrays can be manufactured in a manner that mimics Edison-style filaments. These filaments can be used to reproduce the look of Edison-style bulbs while maintaining low voltage requirements. The low voltage requirements of the LED filament bulbs described herein allow for many outdoor applications.

[0048] The voltage requirements can be changed by wiring the LEDs in different configurations. In many embodiments, wiring the LEDs in parallel minimizes the voltage requirements. In various embodiments, groups of LEDs are wired in series, and then groups of LEDs are wired in parallel to increase the voltage requirements. However, one of ordinary skill in the art will readily recognize that any LED wiring configuration may be used depending on the requirements of a given application.

[0049] The low voltage requirement enables the LED filament array bulb to operate using low voltage batteries, such as but not limited to AA size batteries ranging from 1.2V to 3.7V. In various embodiments, the battery used is a rechargeable battery. The battery can be but not limited to a nickel-cadmium battery, a nickel-metal hydride battery, a lithium-ion battery, or any other battery structure suitable for the requirements of a given application. However, in many embodiments, other energy storage units can be used, such as but not limited to capacitors or any other energy storage device suitable for the requirements of a specific application of an embodiment of the present invention. In addition, the low voltage requirement allows the bulb to be powered by a small solar panel consisting of at least one solar cell. In many embodiments, the solar panel powers the bulb. In many embodiments, the solar panel recharges the battery, which powers the bulb. In many embodiments, the LED filament array bulb hangs downward from the cover member.

[0050] In some embodiments, a transformer can be used to reduce the main line voltage (e.g., 120V in the United States) to any value between 1.2V and 12V. In some embodiments, the transformer reduces the voltage to above 12V or below 1.2V. In some embodiments, the step-down line drives the LED filament array bulb. In several embodiments, when the step-down line is used, the LED filament array bulb is attached to the base member and points upward.

[0051] The LED filament array bulb can be fixed to a socket. In many embodiments, the socket is attached to the housing. In certain embodiments, the housing also has a solar panel, at least one compartment for accommodating at least one battery, and / or a circuit for providing power to the LED filament array bulb. In many embodiments, the solar panel is located on the opposite side of the housing relative to the socket. In various embodiments, the housing is part of a larger structure that can be placed outside to be used as an outdoor light. Discussion of the housing can be found below.

[0052] Low Voltage LED Filament Array Lamps

[0053] Many outdoor lighting solutions use relatively high voltages to drive incandescent lamps, compact fluorescent lamp (CFL) bulbs, and / or any other bulbs that require relatively high voltages. However, relatively small batteries can be used to operate low-voltage LED filament array bulbs. In many embodiments, a small solar panel is used to recharge the battery. This allows the application of low-voltage LED filament array bulbs in outdoor spaces that do not require connection to electrical wires (such as but not limited to consumer 120V power grids). Therefore, the low-voltage LED filament array bulb can be fixed in a housing designed for outdoor use.

[0054] Now turn to Figure 1A , shows a low voltage LED filament bulb in a housing according to an embodiment of the present invention. The cover member 100 has a solar panel 110 facing upward and a socket facing downward, into which a low voltage LED filament array bulb 120 can be assembled. The cover member 100 is assembled to the base member 130. In many embodiments, a transparent housing 140 is arranged between the base member 130 and the cover member 100. The transparent housing 140 can be made of glass, plastic, or any other material suitable for the requirements of a given application. In many embodiments, the transparent housing 140 is cylindrical. However, any shape can be used, such as but not limited to a prism, a polyhedron, or any curved shape suitable for the requirements of a given application. An attachment device 150 is connected to the base member. In many embodiments, the attachment device is a rod or a stick. In several embodiments, the attachment device is a bracket or any other attachment mechanism suitable for the requirements of a given application. In many embodiments, the base member is shaped at the bottom to stabilize the unit in the ground. For example, the base member can be shaped as a spike. The attachment device may have a flange to stabilize the unit on the ground. In various embodiments, the base member is shaped so as to facilitate attachment of the unit to a wall and / or the ground. In some embodiments, the attachment device is two or more parts that fit together.

Figure 1C , a low voltage LED filament array lamp with its attachment device removed according to an embodiment of the present invention is shown.

[0055] As will be appreciated by one of ordinary skill in the art, FIG. 1 illustrates only a single embodiment of the present invention. The cover member and base member may be manufactured to have different appearances. In many embodiments, the transparent cylinder is colored to produce additional lighting effects. In many embodiments, the transparent cylinder is not present. The solar panel and / or the cover member may be tilted to better face the sunlight. Although specific embodiments of low voltage LED filament bulbs in housings are discussed above, one of ordinary skill in the art will appreciate that the components may be rearranged, replaced, or modified as required by a given embodiment. A discussion of the cover member may be found below.

[0064] Now go to Figure 3C , showing the LED filament array bulb being inserted into the socket of the socket component according to an embodiment of the present invention.

[0065] Now go to Figure 3D , showing an LED filament array bulb inserted into a socket of a socket component of a completed cover component according to an embodiment of the present invention. Although the socket component, bulb, and cover component are described above with respect to a specific embodiment of the present invention, a person of ordinary skill in the art will readily appreciate that any number of configurations may be used depending on the requirements of a given application. The following will discuss the low voltage LED filament array used in the LED filament array bulb.

[0066] Low Voltage LED Filament

[0067] LED filament array lamps can operate at low voltages. In many embodiments, the circuitry of the LED filament array can be altered to meet or generate specific operating voltage requirements. One or more LED filament arrays can be wired together in a single bulb.

[0068] Now go to Figure 5A , shows a base support for an LED filament array according to an embodiment of the present invention. The base support 500 can be made of plastic, metal, glass, ceramic, porcelain, sapphire material, or any other material suitable for the requirements of a given embodiment. In the embodiment shown, the base support has a positive lead 510 and a negative lead 520. In many embodiments, the leads are located on opposite sides of the base support. In many embodiments, the leads are located on the same side of the base support. However, any lead configuration can be used depending on the requirements of a given application.

[0069] Now go to Figure 5B, shows a base support portion equipped with LEDs according to an embodiment of the present invention. LED 530 is attached to the base support portion using welding techniques, glue, or any other bonding technique suitable for the requirements of a given application.

In some embodiments, the color temperature can be as high as 6500k. In many embodiments, the fluorescent material 540 is applied so that the LED filament array appears cylindrical.

[0071] Now turn to Figure 5D , shows a completed LED filament array according to an embodiment of the present invention. The circuit of the LED filament array is discussed below.

[0072] LED filament array circuit

[0073] The LED filament array circuit can be modified to use different voltage levels. In many embodiments, the voltage level is determined based on the wiring configuration of the LEDs. Typically, LEDs are wired in parallel so that the voltage across each LED is the same and the total current is the sum of the current through each LED. When wired in series, the current through each LED is the same, but the voltage across the circuit is the sum of the voltages through each LED. LEDs wired in series can have the advantage of maintaining the same current across each LED, which means that the brightness of each LED will remain stable and there is less chance of thermal runaway. However, by coating the LEDs with a fluorescent material, any variations in the brightness of the LEDs can be mitigated.

[0074] Now go to Figure 6, shows a circuit diagram of a parallel circuit for an LED filament array according to an embodiment of the present invention. The LED filament array can have a positive lead 600 and a negative lead 610. In the embodiment shown, the LEDs 620 are wired in parallel between the leads. The LEDs can be evenly spaced, unevenly spaced, or placed in a pattern between the leads as required by a given application. In some embodiments, each LED filament array has 20 LEDs. However, any number of LEDs can be used as required by a given application. By wiring the LEDs in parallel, the voltage across the LED filament array is the same as the voltage of each unit. In many embodiments, the voltage of each LED is between 1.4V and 3.2V. In some embodiments, the voltage can be higher than 3.2V, such as 12V or 15V. However, any voltage can be used as required by a given application.

[0075] Now go to Figure 7 , shows a circuit diagram of a hybrid parallel / series circuit for an LED filament array according to an embodiment of the present invention. Circuit 700 includes at least two LED sub-arrays 710 wired in series. Within circuit 700, each sub-array is wired in parallel to the other sub-arrays. In many embodiments, at least two sub-arrays of LEDs are wired in series, and at least two sub-arrays are wired in parallel. In this way, the voltage across the entire LED filament array is the same as the voltage across each sub-array. The number of LEDs in each sub-array can be varied to achieve a specific voltage. In many embodiments, each series has 4 LEDs each operating at 3V for a total of 12V on the circuit. However, any number of LEDs may be used as required by a given application.

The LEDs can be wired in series to achieve additional voltages on the circuit. Although specific circuits and multiple LEDs are shown in the above figures, it will be understood by those of ordinary skill in the art that any number of LEDs and wiring configurations can be used as required for a given application. In order to power the LED filament array bulb, a control circuit can be used to regulate the amount of electricity used.

[0078] The control circuit can be housed within a cover member of the low voltage LED lamp unit. In many embodiments, the control circuit controls the flow of power between at least two of the solar panel, the LED filament array bulb, and the battery. In many embodiments, when the solar panel is exposed to light, the control circuit directs power from the solar panel to the battery to charge the battery.

In this way, during the day, the battery can be charged and the light will be turned off, and at night, the battery can be used to operate the light. In many embodiments, when the solar panel is exposed to sufficient light, the voltage of the solar panel is greater than the voltage of the battery, and the control circuit directs electricity from the solar panel to the battery, and no current will flow through the LED filament array bulb. In many embodiments, when the solar panel is not exposed to sufficient light, the voltage of the solar panel is lower than the voltage of the battery, and the control circuit discharges from the battery through the LED filament array bulb until the battery voltage is lower than its protection voltage. In various embodiments, the solar panel directly powers the LED filament array bulb. The control circuit design is described below.
