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.

An illumination device, which comprises a light source and a battery to power the light source, provides improved light output without the need for complicated and therefore expensive optical arrangements by including a nonimaging light guide which collimates and optionally diffuses light emitted by the light source. In a particular embodiment of the invention these improvements are implemented in a multipurpose solar light which includes a solar panel, wherein the battery stores energy generated by the solar panel. The illumination device may comprise a casing having a front casing portion and a rear casing portion, wherein the nonimaging light guide is integrally formed with the front casing portion. The nonimaging light guide may have a shape comprising two conical frusta. Furthermore, the nonimaging light guide may comprise a recess in which the light source is located, the recess being larger than the light source such that there is a gap which permits airflow and in turn removal of heat from the light source as well as improved optical coupling.

The disclosure comprises a stylus and a touch control system. The stylus comprises a pen body, a pen tip, and a light emitting device. The light emitting device is provided at the pen tip. A non-contacting end of the pen tip is connected to a bottom end of the pen body. The pen body is provided with a control module inside the pen body. The control module is electrically connected to the light emitting device and controls the light emitting device to emit light when a contacting end of the pen tip is applied to a reflective display.

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.

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 lighting system has a power source formed by a solar panel and a battery assembly, a lighting assembly having a plurality of lighting devices arranged into a plurality of lighting groups, the light assembly having a predetermined maximum power, and a multiple-input power converter electrically coupled to the power source and the lighting assembly for powering the lighting assembly using the power source, and for charging the battery assembly using the solar panel. The multiple-input power converter is configured for calculating a power upper-bound based on the level of stored energy in the battery assembly and the length of a night time, and selecting at least a subset of the lighting groups and powering the selected lighting groups for illumination using the battery assembly for preventing exhausting the stored energy of the battery assembly before the battery assembly can be charged by the solar panel.

A decorative lawn ornament including a rotatable carrier having a plurality of blades. At least one light-emitting device is arranged on each of the plurality of blades to emit light from the blades. A solar panel is provided to receive and collect sunlight, and a photoswitch is automatically operable between an activated state during instances of insufficient sunlight to thereby activate the light-emitting device, and a deactivated state during instances of sunlight to thereby deactivate the light-emitting device. The decorative lawn ornament is operable such that when a flow of air strikes it, the blades rotate and a decorative member rotates to control an orientation of the blades and the light emitted by the light-emitting devices.

A beacon device to be installed on a tower, the device including: an electric energy generating unit comprising: at least one photovoltaic module able to be wound over at least part of the circumference of the tower, and a light energy generating unit configured to be fastened on the tower the light energy generating unit comprising: a housing having a periphery, a storage member storing the electric energy generated by the electric energy generating unit, a regulating member regulating the charge of the storage member, and a light-emitting member supplied by the storage member, the light-emitting member extending over the periphery of the housing.

A lighthouse includes a mast device and a lighting device mounted on the mast device. The lighthouse further includes a main body including a box body and a top cover, the top cover is arranged on a top of the box body, the top cover and the box body define a receiving chamber, and the top cover is movable or detachable relative to the box body to open or close the receiving chamber. The lighthouse is convenient for overhaul and maintenance, and improves the maintenance efficiency.
