Abstract: A portable solar-powered lighting assembly that includes a lighting device including a light source, a rechargeable battery, and a first engagement interface. The light source is electrically connected to the rechargeable battery. The assembly includes a fastening device including a distal tip, a fastening element, and a second engagement interface. The fastening device is configured to selectively couple with the lighting device in response to the second engagement interface mating with the first engagement interface. The fastening device is configured to secure the lighting device to a surface in response to the fastening device penetrating the surface via the distal tip, and secure the lighting device to a tool in response to the fastening device receiving the tool through the fastening element.

Abstract: Modular and portable solar-powered charging devices are described. The solar-powered device may include a housing, a rechargeable battery disposed within the housing, and a solar panel positioned along an exterior of the housing. The solar panel is electrically connected to the rechargeable battery. The solar-powered charging device is configured to transfer electrical power generated by the solar panel and stored in the rechargeable battery to a second solar-powered charging device when the housing is positioned adjacent to the second solar-powered charging device.

Abstract: Solar-powered lighting devices are described, the solar-powered lighting devices including a housing and an electronic cord coupled to the housing. The housing may include a first section coupled to a second section, the first section including a solar panel coupled to an outer surface. The lighting devices may also include a rechargeable battery, a microprocessor, and a user interface to receive user input and transmit the user input to the microprocessor. The electronic cord may be flexible and includes at least one light-emitting diode, wherein the microprocessor is configured to control at least one operating mode of the LED of the electronic cord based on the user input.

Abstract: Lighting devices are described and may include a housing, a solar panel, and at least one speaker. The housing may include a cover and a base coupled to the cover. The lighting device may also include at least one rechargeable battery, a microprocessor, and a plurality of light sources, such as LEDs, configured to emit light towards the cover. The solar panel, the rechargeable battery, the microprocessor, the speaker, and the plurality of light sources may be in electronic communication with one another. Further, for example, the microprocessor may be configured to control at least one operating mode of the plurality of light sources and at least one operating mode of the speaker.

Abstract: A lighting element for a solar powered lantern is formed integrally with a bottle closure which can be threaded onto a discarded plastic bottle, such that the light emitting diodes (LEDs) of the lighting element extend into the bottle. The lighting element is powered by a rechargeable battery which is recharged by a photovoltaic panel positioned on the top surface of the bottle closure.

Abstract: A solar powered lamp is provided with flat ends and a translucent flexible housing, such that the housing can be inflated to form a free standing cylinder. A solar panel faces outward on one of the flat ends for recharging a low-profile rechargeable battery which, under the control of a printed circuit panel, powers an array of LEDs, which point into the lamp housing. Reflective surfaces, facing each other on opposite inside end walls of the lamp, maximize the diffusion of light from the LEDs. The lamp is a durable, portable, long light lighting solution for those who live off the electric power grid, victims of disaster, and the like.
