An anchoring weight is configured to connect to the capturing assembly. The anchoring weight has an opening. The upper capturing housing and lower capturing housing are configured to retain the anchoring weight.

A lighting assembly includes a lighting tower. The lighting tower includes a plurality of layers of lighting elements, where each layer of lighting elements is configured to provide a different angle of emitted light onto a parabolic reflector with respect to light emitted from another layer of lighting elements onto the parabolic reflector when activated.

A lamp includes at least two illumination parts and a lamp body. The lamp body has an upper portion, a lower portion corresponding to the upper portion and at least two optical cavities extended between the upper portion and the lower portion. The illumination parts are respectively arranged in the optical cavities. The lamp has a surrounding lighting state and a side lighting state. The lighting states of the lamp may be switched between the surrounding lighting state and the side lighting state through controlling the operating modes of the illumination parts in the optical cavities respectively.

water ripple lamp includes: a housing assembly, a first water ripple light-transmitting plate, a water ripple light-transmitting tube assembly and a limiting assembly. The housing assembly is configured to define at least one light outlet. The first water ripple light-transmitting plate is configured to cover the at least one light outlet. The water ripple light-transmitting tube assembly is arranged inside the housing assembly. The water ripple light-transmitting tube assembly is configured to be rotatable. The water ripple light-transmitting tube assembly includes: a water ripple light-transmitting tube and an outer ring fixed to the water ripple light-transmitting tube. The limiting assembly includes a retaining ring and a bearing structure. The bearing structure is fixed to the retaining ring. The bearing structure includes a bearing. The bearing abuts against the outer ring, and is rollable relative to the outer ring.

An underwater directional light is provided. The directional light includes a lamp assembly, a tube assembly, and a printed circuit board assembly. The lamp assembly includes a housing and a lamp having a plurality of lighting elements. The tube assembly is coupled to the lamp and has a hollow interior. The printed circuit board assembly is mechanically coupled to the tube assembly and electrically coupled to the lamp.

A lighting device that is capable of illuminating in all directions includes: a case that includes a plurality of wall portions each including a face in a polygonal shape; a plurality of light-emitting elements that are provided in the plurality of wall portions and emit light toward outside of the lighting device; and a controller that controls the plurality of light-emitting elements separately. The case is of an outer shape that is spherical or polyhedral. The case includes bent portions that are bent in the outer shape of the case. The bent portions constitute at least three sides of the outer shape of the case.

An area light is provided including a housing defining a central axis having a first end, a second end opposite the first end, and a side portion; a cover mounted on the first end of the housing; a light module disposed on the first end of the housing, the light module comprising a heat sink and at least one light-emitting diode (LED) to emit light through the cover and in a direction that extends 360 degrees around the center axis; and a battery receptacle disposed on the side portion of the housing to receive a removable battery pack and supply electric power form the removable battery pack to the at least one LED. At least one hook is provided on or adjacent the first end of the housing.

Methods and systems for integrating multiple, vertically oriented laser diode emitters into a low cost package suitable for high volume manufacturing are presented herein. Multiple laser diode based emitters are assembled on a mounting structure, which, in turn, is fixed to an insulated metal substrate. Each of the multiple laser diode based emitters are oriented such that the light output generated by each laser diode based emitter is aligned with a direction perpendicular to a mounting surface of the insulated metal substrate. In a further aspect, the insulated metal substrate includes electrically conductive layers disposed on the topside and backside of the thermally conductive metal core layer. Portions of the topside and backside electrical layers are electrically coupled such that the laser diode based illumination device is configured as a surface mount device amenable to low cost, surface mount, electronics manufacturing assembly processes.
