The present invention relates to a dynamic lighting device, including at least two lamps and a base. Each of the at least two lamps is connected to a respective paired flexible stalk configured to rotate in a circumferential direction of the base. When the flexible stalks rotate in the circumferential direction of the base, due to dynamic bending deformation of the flexible stalks, the at least two lamps have random movement in an upright direction and the at least two lamps have circumferential random wiggles against a joint defined between the flexible stalks and the base as a pivotal point.

A solar street lamp includes a connecting base configured with a mounting port for mounting the solar street lamp on top of a lamp post. A bottom plate has a rear portion mounted on top of the connecting base, the bottom plate has a lower surface upon which is mounted, in a forward portion of the bottom plate, a plurality of light-emitting modules. A solar panel is supported above the bottom plate and separated from the bottom plate by a distance of a wiring gap space, as meaning approximately a minimal gap needed to permit wiring for interconnections of components on the solar street lamp. A battery stores energy received from the solar panel, and a power supply provides power from the battery to the light-emitting modules. The battery and power supply are mounted below the bottom plate, inside a mounting chamber formed in the connecting base. A rear plug is detachably disposed on a rear edge of the connecting base such that, when attached, the rear plug provides a seal to an opening in the mounting chamber of the connecting base and a rear seal to the wire gap space separating the solar panel and the bottom plate and, when detached, provides an access for maintenance to the power supply and battery mounted in the mounting chamber and permits the solar panel to be withdrawn from the solar street lamp.

Exemplary embodiments of a rotating light device are provided. In some exemplary embodiments, a light apparatus is provided, having a circular body portion configured to retain one or more batteries, a circular cover portion threadably secured to the circular body portion and having a transparent enclosure, a printed circuit board placed between the circular body portion and circular cover portion containing one or more light-emitting diodes configured to project light from the transparent enclosure, and a tension spring placed between the circular body portion and circular cover portion that provides tension between the circular body portion and circular cover portion, and pushes the circular cover portion away from the circular body portion, wherein rotation of the circular cover portion completes an electrical circuit to turn the one or more light emitting diodes on. In some exemplary embodiments, a holder is provided to hold the light apparatus within the holder.

A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.

A tablet docking station comprising a tablet dock configured for receiving a tablet, an upper post extending from the tablet dock, and an extension arm extending from the upper post. The spray tubing can be mounted to the extension arm. The spray tubing provides a water mist for cooling a user when the spray is activated. The tablet docking station optionally includes a fan assembly including a fan housing. The spray tubing has one or more spray outlets configured to provide a water mist for evaporative cooling of an area near a user. The tablet docking station may provide an electronic control for the fan assembly providing a fan control speed adjustable by a graphical use interface on the tablet.

Aspects of the disclosure are directed to a multi-functional streetlight. In accordance with one aspect, the multi-functional streetlight includes a hexagonal shaped support structure, wherein the hexagonal shaped support structure includes an arm segment and wherein the arm segment includes a luminaire on an under side of the arm segment; and a base flange configured to couple the hexagonal shaped support structure to the ground.

A solar energy device includes a solar panel array including a plurality of solar panels, each of the solar panels being divided into solar sub-panels. The solar sub-panels have unequal shapes but equal areas. Wires electrically connect the solar sub-panels and connect the solar panels. The solar panels are secured on a base which is formed with cutouts to receive the wires. The wires are fixed to the solar sub-panels but are free to move with respect to the base.

Vibration devices are described that provide soothing movement or motion to a person, such as an infant or toddler, laying in a bed. The vibration devices are not part of, but are separately attachable to/removable from, the bed. The vibration devices utilize a control section that is outside the bed and a passive or active transmission element located underneath the mattress that transfers vibration motion to mattress the person is laying on. The devices described herein may also produce noise resulting from the generated movement that may be soothing to the person laying on the mattress.

An AC-DC photovoltaic device is provided, including: a photovoltaic module, a direct current side capacitor, a DC-PWM power switching circuit and a controller. The direct current side capacitor is connected in parallel with an output terminal of the photovoltaic module. An input terminal of the DC-PWM power switching circuit is connected with the output terminal of the photovoltaic module. The DC-PWM power switching circuit includes a controllable switch transistor. The controller is configured to output a switch control signal to control a switching state of the controllable switch transistor in the DC-PWM power switching circuit, to control the DC-PWM power switching circuit to output a direct current PWM wave in a case that the switch control signal is a direct current modulation signal, and output an alternating current PWM wave in a case that the switch control signal is an alternating current modulation signal.
