The AC power ports of respective lighting fixtures are coupled together with a plurality of industrial power cables without using one or more conduits for the plurality of industrial power cables. The network communications ports of the respective lighting fixtures are coupled together with a plurality of waterproof network communications cables. In one example, a lighting system kit comprises two or more lighting fixtures having an AC power port comprising an industrial type connector. The kit further comprises multiple industrial power cables and one or more industrial drop tee cables.

In various embodiments, a lamp is provided. The lamp may include a mounting board; at least one semiconductor light source arrangement arranged on the mounting board and comprising a base, which is provided with base contacts for supplying energy to the at least one semiconductor light source arrangement and which is compatible with a standardized incandescent lamp base; and at least one insulation displacement contact to make electrical contact with the at least one semiconductor light source arrangement.

A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding MC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.

A light emitting device includes at least one light emitting element, a resin member including, a front surface provided with a recess in which the at least one light emitting element is mounted, a back surface, a bottom surface, an upper surface, a first lateral surface, and a second lateral surface; a first lead including a first inner lead portion and a first outer lead portion; and a second lead including a second inner lead portion and a second outer lead portion. Each of the outer lead portions includes a first-outer-lead base portion along the bottom surface, and first and second bent portions which are extended toward the upper surface side. The resin member is not arranged in at least a portion of a region between the second bent portion of the first outer lead portion and the first bent portion of the second outer lead portion.

A system can configure a luminaire for providing illumination of a selected color temperature, a selected lumen output, or a selected photometric distribution. The luminaire can comprise at least two light sources that have different illumination characteristics, for example different color temperatures, different lumen outputs, or different photometric distributions. The system can configure the luminaire to operate a first of the two light sources, a second of the two light sources, or both of the light sources based on an input. When the luminaire is configured to operate both of the light sources, the luminaire can produce illumination having a color temperature, a lumen output, or a photometric distribution that is different than either of the two light sources.

A dual-color light string comprising a first insulated electrical wire cord, a second insulated electrical wire, two light-emitting diode devices (LED devices) and transparent glue. The first insulated electrical wire is partially exposed to form a first soldering section. The second insulated electrical wire is partially exposed to form a second soldering section. The two LED devices are respectively electrically connected to the first soldering section and the second soldering section, and the directions of bias of the two LED devices from the first soldering section to the second soldering section are opposite to each other; The transparent glue covers the two LED devices, the first soldering section and the soldering section, extends to partially cover a first insulating layer of the first insulated electrical wire and a second insulating layer of the second insulated electrical wire.

To provide, in a simple and cost-effective manner, a planar light-emitting module with reduced thickness as a whole, with its substrate end ensuring shock resistance and low risk of injury, and being excellent in transferring and dissipating heat. A light-emitting module of the present invention includes: a bezel having a leg part having an inner height H; a planar light-emitting tile; and a printed circuit board having a plurality of heat dissipating through holes. A heat dissipating interval is provided between the printed circuit board and the mounted surface. The printed circuit board includes a tile-side main surface being a soaking metal layer including through hole openings.

The disclosed technology includes a water-resistant lamp assembly for preventing interference with the operation of an electric lamp due to leaks. The water-resistant lamp assembly may include a gasket that provides a seal with the bottom of the base of the lamp holder to prevent water from entering the internal cavity of the lamp holder. The gasket may further shield internal electrical conductors from exposure to water that has leaked into the internal cavity of the lamp holder.
