An elongated lighting module having an asymmetric illumination source formed from at least two rows of light emitting diodes (LEDs) that extend along the long axis of the module and are independently controllable. The illumination source is rectangular and oriented so that the rows of LEDs extend along the long axis of the module. The module has couplings at each end that allow additional modules to be interconnected therewith using a linking member and a clamp. The lighting modules are powered via a wiring harness that extends down a support pole to a power converter stack having LED drivers to control the modules.

A connector keying system includes at least one keying device including a flange portion and a keying portion. The flange portion includes a front surface and a back surface. Each of the front surface and the back surface extend substantially parallel to a flange plane. The flange portion further includes a connector aperture extending through the flange portion. The keying portion extends around an aperture perimeter of the connector aperture and projects outward from the flange portion. The keying portion includes and extends between a first key end located at the front surface and a second key end opposite the first key end. The second key end defines a keying perimeter about the connector aperture. The keying portion has a height between the first key end and the second key end and the height is inconsistent between the first key end and the second key end along the keying perimeter.

A track section for a track system is provided that includes an enclosed channel and first and second lateral members. The enclosed channel is defined by a base wall, a cover wall, and first and second lateral side walls, and has an interior cavity. The first and second lateral side walls are disposed on opposite sides of the enclosed channel. The base wall and the cover wall are spaced apart from one another and extend between the first and second lateral side walls. The first lateral member extends outward from the first lateral side wall and the second lateral member extends outward from the second lateral side wall. Each has a ramp flange channel. The track section is a unitary structure with the first and second lateral members being integral with the enclosed channel and has a length between first and second lengthwise ends.

A connector includes a male end and a female end. Specifically, the male end includes a male housing and first lap joints. The first lap joints are disposed on the male housing and are soldered to a first PCB. First lap joint portions, extending forward and having elasticity, are disposed on the first lap joints. The first lap joint portions are in a geometry shape of wave-shaped thin plate. The female end includes a female housing and second lap joints. The female housing is matched with the male shell. The second lap joints are disposed on the female shell, and are soldered to the second PCB or electrically connected to the conductive wires. Second lap joint portions, extending forward and having elasticity, are disposed on the second lap joints.

Hybrid optical cables, hybrid optical connectors, and hybrid optical adapters are disclosed. In one embodiment, a hybrid optical connector includes a connector housing having an insertion portion, wherein the insertion portion is asymmetric with respect to a mid-plane of the connector housing that is positioned in an optical axis of the hybrid optical connector. The hybrid optical connector further includes a ferrule disposed within the connector housing, and a first hermaphroditic electrical contact and a second hermaphroditic electrical contact disposed within the connector housing adjacent opposing sides of the ferrule.
