Various embodiments of dual-powered lighting devices are described. In some examples, the device includes a light source, a first power source, a second power source, and one or more switching devices. The switching device switches between the first power source and the second power source to power the light source.

A lamp comprises a lamp body and a connecting rod assembly. The connecting rod assembly is alternatively connected to a first connecting member or a second connecting member respectively to define a first use state and a second use state. When in the first use state, one or more connecting rods of at least three connecting rods which are connected successively in an axial direction define a lifting rod, and a first end of the lifting rod is connected to the first connecting member. When in the second use state, first ends of the at least three connecting rods are connected to the second connecting member, and second ends of the at least three connecting rods are spaced apart from each other to define a placing plane within which a vertical projection of a center of gravity of the lamp body is located.

A double walled illuminated vessel for displaying indicia comprising an outer sleeve, an inner liner, a lens, a transparent or translucent connection ring, a base and an illumination module adapted to be inserted into the base whereby the base and connection ring are connected to each other creating a base illumination unit. Light from the illumination module passes through the hollow space between the outer sleeve and the inner liner such that the lens bearing indicia is illuminated thus prominently displaying any desired graphic, logo, design, trademark, symbol, letter, number or any other indicia. The connection ring transmits and diffuses light through the inner liner and upper rim as well as the sidewall of the connection ring. The base illumination unit is removable from the outer sleeve and can be used as an independent light source by a user. Additionally, the illumination module is rechargeable in one embodiment and can provide an adequate charge to a mobile device. Further embodiments provided for a removable lens or lens unit.

A photovoltaic renewable energy system utilizes a light source and one or more reflectors to produce power via photovoltaic cells. An exemplary photovoltaic renewable energy system utilizes a light source, such as Light Emitting Diodes (LED), to provide light to photovoltaic cells that therein produce electrical power. The photovoltaic cells may be arranged in a photovoltaic array to ensure maximum power conversion from the incident light. A reflector, such as a prism may be used to direct light from the light source onto the photovoltaic cells. A cell reflector, which may also be a prism, may be configured proximal to the photovoltaic cell surfaces to reflect light onto the photovoltaic surface to increase power conversion.

A storage device for storing a removable flashlight. The storage device includes an electrical switch surrounded by a cover plate. A power source is electrically connected to the electrical switch. A removable flashlight is removably connected to the cover plate. The removable flashlight is stored in the storage device and removable from the storage device when needed for use.

A nail lamp has a removable, rechargeable battery pack and a translucent shell formed by double-injection molding. The lamp is portable can be operated cordlessly using the battery pack. The translucent shell glows when the lamp's treatment chamber is on. Surface-mounted light emitting diodes (LEDs) illuminate the treatment chamber with multiple wavelengths ultraviolet (UV) light. The battery pack has a USB port which allows a customer to conveniently charge a device (e.g., smartphone) while the customer's nails are being worked on. The battery pack has a battery gauge, which indicates a charge level remaining for the battery. When the battery pack is low on charge, the battery pack can be swapped with a charged battery pack. A battery pack can be charged while inserted in the lamp or removed from the lamp. The LEDs of the nail lamp are passively cooled.

A signaling device is disclosed comprising an electronic circuit positioned within a housing and comprising at least one LED, a light diffuser manufactured from a non-opaque material and a USB Port. Side edges of the housing each comprise a barb engaging slot therein. A cap end covering the USB port and comprising a pair of flexible fingers each comprising a barb-like feature for engaging respective ones of the barb engaging slots comprises an actuating part fabricated from a compressible rubberlike material which is secured towards a second end of each of the flexible fingers. Compressing the actuating part motivates the outer ends of the flexible fingers to move apart, thereby releasing the barb-like features from their respective barb engaging slot and allowing the cap to be removed from the housing.

A flashlight having a housing, a light-end assembly, and a user interface. The light-end assembly, which may be coupled to an end of the housing, may comprise a flexible light component having a proximal end and a distal end. A first plurality of light emitting diodes (LEDs) may be distributed on the first flexible light component between the proximal end and the distal end. The flexible light component may include a flexible, semi-rigid structure to maintain the flexible light component in a desired shape or position.
