A lighting device, preferably a LED, includes a profiled element adapted to be applied to an external structure and coupled to a transparent or translucent longitudinal portion that allows the passage of a luminous flux generated by an illuminating element, preferably a LED strip, housed within a longitudinal chamber defined inside the profiled element. The profiled element also houses, in facing relationship to the illuminating element, a reflecting element oriented to reflect the luminous flux generated by the illuminating element toward the transparent or translucent longitudinal portion of the profiled element. The longitudinal chamber housing the illuminating element is separate from a second longitudinal chamber defined inside the profiled element and housing the reflecting element.

A multi-conductor bus with radially arranged conductor wires on which addressable bead devices that may incorporate light-emitting diodes (LEDs) or other surface mount devices (SMDs) can be easily mounted. The radial bus is designed to provide an improved range of flexibility and motion while allowing for easy addition of bead devices along its length that utilize self-addressing bus protocols such as cascading device protocols. The design of the flexible, interruptible radial bus facilitates the use of pass-through and interrupted paths along the bus that simplifies the installation of addressable devices along the bus such as the bus-mounted bead devices disclosed herein.

A lighting device 1 includes a circuit board that is long and flexible, light emitters mounted in a row on the circuit board, and an elongated cover. The cover includes (i) a translucent member that is made of translucent soft material and that covers the circuit board and the light emitters, and (ii) a phosphorescent member containing a phosphorescent material that is to be excited by light emitted by the light emitters. The phosphorescent member is arranged on a second area portion of the cover other than a first area portion of the cover that is located in an emission direction of light from each of the light emitters and a luminous intensity is equal to or greater than a standard luminous intensity in the emission direction.

A flexible cover for a linear lighting channel is described, as are enclosures and luminaires using this kind of flexible cover. The flexible cover has sufficient flexibility to be bent or coiled to a bend radius of 6 inches (15.2 cm) or smaller, and can thus be coiled for shipping and uncoiled for installation. Typically, the cover is made of a polymer that is at least translucent. Covers may be made in various shapes, including lens and prism shapes, and channels may be made with sidewalls that make complementary shapes in order to engage with and retain the covers.

An electrodeless surface-mounted LED string light, a method and an apparatus for manufacturing the same are disclosed. The electrodeless surface-mounted LED string light includes: a first wire and a second wire; a plurality of LED units, wherein each LED units includes two surface-mounted LEDs, and luminous surfaces of the two surface-mounted LEDs are opposite to each other, and the luminous surfaces of the two surface-mounted LEDs are parallel to an axial direction of the first and second wires; and a plurality of encapsulants respectively encapsulating the two surface-mounted LEDs of the plurality of LED units therein.

A light string is provided. The light string includes a plurality of light-emitting components, a first polyvinyl chloride covered wire and a second polyvinyl chloride covered wire. The light-emitting components are configured to emit light having a same color or different colors. A first polyvinyl chloride covered wire is electrically connected to a first terminal of each of the light-emitting components and a first power terminal of a power supply component. The first polyvinyl chloride covered wire receives a first voltage from the first power terminal of the power supply component. The second polyvinyl chloride covered wire is electrically connected to a second terminal of each of the light-emitting components and a second power terminal of the power supply component. The second polyvinyl chloride covered wire receives a second voltage from the second power terminal of the power supply component.

A lighting controller and a method of switching a light string between a plurality of lighting modes, and a light string assembly are provided. The lighting controller includes a control box, a switch power source circuit, and a lighting control circuit. A switching component is disposed on the control box. The switch power source circuit and the lighting control circuit are accommodated in the control box. The switch power source circuit is triggered to allow a power supply component to supply power to the light string during a predetermined time by the switching component receiving a turning-on timing trigger and allows the switching component to receive a plurality of lighting triggers. The lighting control circuit switches the light string between the plurality of lighting modes to exhibit a variable lighting effect according to the plurality of lighting triggers.
