LED lamp 10 includes a housing, a mounting base, a light engine (LE) 16, light-transmissive cover 20 circumscribing the LE, and reflector 18. The LE comprises a plurality of top-emitting LED packages (TE-LED packages) mounted on planar upper surface 32 of PC board 26, each configured to emit light having an angular distribution centered around a principal light-emitting direction (PLED) normal to an emission face 45. A first set 36 of TE-LEDs is mounted with its PLED perpendicular to PCB 26 and a second set 38 of TE-LEDs is mounted to the PCB with its PLED orthogonal to that of the first set 36 of TE-LEDs and parallel to upper surface 32. Reflector 18 disposed below LE 16 reflects light towards cover 20. A polar light distribution of light emitted from LED lamp 10 is omnidirectional and is Energy Star compliant.

An example low voltage buss system is provided. The low voltage bus system distributes low voltage DC power into the office workspace in a manner that reduces clutter and promotes customizable and efficient workspace usage. The low voltage bus system distributes low voltage DC power into the office workspace via an electrical buss having a connector at the end of the buss to distribute low voltage DC power to and throughout office workspace and, in particular, office furniture.

Methods, systems and devices associated with an electronic candle are disclosed. In one example aspect, an electronic candle includes a mounting frame that includes a first connector and a power supply assembly that is detachable from the mounting frame. The power supply assembly includes a second connector that forms a coupling mechanism with the first connector. The power supply assembly further includes an energy storage, a first power source configured to charge the energy storage, and an electrical connection interface configured to connect the power supply assembly to a second power source. The electronic candle also includes a light-emitting assembly that is removably coupled to the mounting frame configured to operate using power provided by the power supply assembly, and one or more controllers configured to control an operation of the light-emitting assembly.

A lighted fishing pole holder has a top mount that is attached to the gunwale in the usual way, the top mount having an upper surface, a lower surface seated on the gunwale and a central opening. The top mount has a fishing pole receiving tube member depending downwardly therefrom. The tube member has a base such that a light element is positioned on the base, either atop or embedded therein, the light elements facing toward the central opening. The light element is connected to the boat's electrical system or to a battery and issues light into the tube member which is directed out through the central opening of the top mount. A remote control can control various operations of the light element.

A luminaire includes a housing with a cavity, a non-planar lens, and a light emitter. The non-planar lens is coupled to the housing. The lens defines a generally circular footprint and a concavo-convex shape. The light emitter is positioned proximate an edge of the cavity and is configured to emit light into an edge of the lens and toward a center of the cavity.

A method for increasing the yield of a flowering plant includes positioning a lighting device with respect to a lower minor height of the flowering plant. The method includes irradiating the lower minor height with light in a predetermined range of the electromagnetic spectrum for a duration of a flowering stage of a life cycle of the flowering plant. The lighting device may be an annular clamshell design that circumscribes a stalk of the flowering plant. Such a design may be clamped to the stalk via a spring force of a pair of spring-loaded clamps. The lighting device may include a plurality of red LEDs arranged in an arcuate manner. At least 80 percent of the light from the lighting device is in the predetermined range of 580 nm to 780 nm, and may be in the range of 600 nm to 700 nm.

A main light and a secondary LED light for generation lumination of particular light characteristics in a particular direction. This includes an LED lighting fixture having a main light in a ceiling/wall lamp and a nightlight transmitting nightlight illumination along a ceiling. Downlights are disclosed having a main illumination source a secondary lumination source as a nightlight or some other illumination.

An intelligent lamp group includes a central lamp and at least one peripheral lamp. The central lamp includes a first lamp housing, a first light emitter, a first lampshade, a video camera module, an external memory and a system-on-chip. The first light emitter is disposed on the first lamp housing. The first lampshade covers the first light emitter. The video camera module is fixed in the first lampshade. The system-on-chip of the central lamp having a combo wireless communication module is configured to build a local wireless network to connect all the peripheral lamps, hence the user can only focus on the central lamp to achieve the remote control for the central lamp and all the peripheral lamps. In addition, through the combo wireless communication module, the central lamp can build an internet connection with the user's mobile device for the light remote control and the security monitoring.
