Abstract: A solar fan has a solar panel deposited inside a transparent protective plate that is positioned at a surface of a casing, so that solar energy can be converted into electricity that is then transmitted to a solar cell in the casing for storage. The solar fan has two blade sets that can be angularly adjusted with respect to a case of the casing.

Abstract: A mini solar portable multi-device includes a solar module for converting solar energy and transmitting electric energy to a battery inside the body, a radio control circuit board that has a connector set and an audio changeover switch, and a loudspeaker seat holding a loudspeaker that sounds audio signals or acoustic warnings and a light-emitting member control circuit board that has a light-emitting member, a light-emitting control circuit, a brightness and light-emitting mode touch switch, and a light-detection control circuit for providing consistent illumination or warning flashes. The device performs self-charging under sunlight or gets charged by the grid, and then charge an external cell phone. The front cover has buttons communicated with the radio control circuit board for selecting playing modes, for switching tracks, for adjusting volume, for playing or stopping, and for playing and pausing music and switching between radio stations, respectively.

Abstract: A solar-lamp assembly includes a main frame, a secondary frame mounted atop the main frame and having solar wafers and a photoelectric-transducing-and-controlling element; a housing attached below the main frame for accommodating therein a battery; a post connected below the housing; at least one electrically interconnected lamp element connected below the main frame by a respective lamp shade and including therein at least one lighting device, wherein the battery, the lamp element, and the photoelectric-transducing-and-controlling element are electrically connected; a flexible board provided between the lamp element and the main frame, wherein the flexible board allows a plurality of the lamp elements to project light in different directions; and at least an arm-shaped lamp supporter connected with one lateral of the housing and having at least one lamp element affixed thereto through another flexible board.

Abstract: A movable light bar assembly includes a primary frame having a side coupled with a secondary frame and an opposite side coupled with at least one lighting element and a battery element. The secondary frame has a surface provided with solar chips and is provided internally with a photoelectric transducer electrically connected to the battery element and the at least one lighting element. Each lighting element is provided with at least one light-emitting body and secured to the primary frame by a lamp cover. The battery element is secured to the primary frame by a battery cover. The primary frame is peripherally provided with at least one rotatable handle which, when angularly offset from the primary frame, serves to support the primary frame. The at least one handle is insertable into a fixing base and connectable with a hanging cord. The primary frame can be positioned at a lamp frame.
