An apparatus, manufacture and method of illumination support being a single monolithic substrate with light emitting diodes mounted on the external sides of the monolithic substrate. The necessary circuitry for the LEDs is embedded in one or more rigid or flexible electrical substrate that is affixed to one or more of the external sides of the monolithic substrate. The two terminal ends of the monolithic substrate are designed to fit into the lamp sockets of an existing or new light fixture without the use of end caps or end socket adapters, which provides structural support for the monolithic substrate.

A lamp system (10) includes a straight tube type lamp (13) and a socket (14). The straight tube type lamp (13) includes a straight tube type cover (20) containing a light-emitting element, and caps (23) arranged at both ends of the cover (20). A pair of lamp pins (30) whose tips respectively protrude in directions intersecting a lamp longitudinal direction are protrudingly provided on end faces of the caps (23) at both the ends. The socket (14) includes a socket body (41), a rotor (42) which is arranged in the socket body (41) and on which the pair of lamp pins (30) of the straight tube type lamp (13) are mounted, and a pair of terminals to which the pair of lamp pins (30) mounted on the rotor (42) are connected. At least the rotor (42) can move in the lamp longitudinal direction.

A lighting device includes a housing including a hole; a light source body including a light emitting module with a terminal; and electrical connection means including a portion projecting through the hole and having a connector electrically connected to the terminal and physically connecting the housing with the light source body.

A tube that is at least partially optically transmissive. An LED mounted on a substrate is positioned in the tube and is operable to emit light through the tube when energized through an electrical path. Pins are in the electrical path. An electrical conductor electrically couples the pins to the electrical path, the electrical conductor is biased into engagement with an electrical contact on the substrate. The substrate may be secured to the tube by an adhesive. The substrate may be secured to the end caps and be suspended in the tube.

An LED light fixture assembly includes an elongated first support member, an elongated second support member spaced from and substantially parallel to the first support member, and a plurality of elongated LED lighting fixtures coupled to and extending between the first support member and the second support member. Each LED lighting fixture includes an elongated structural frame member having a substantially channel shaped support portion, and a mounting portion opposite the support portion. Each LED lighting fixture also includes a plurality of LED light modules secured to and positioned along the mounting portion, and a cover extending along and supported by the mounting portion. The cover is positioned so light emitted from the plurality of LED light modules passes through the cover and away from the mounting portion.

Provided in this disclosure is an electrical bus system for use with a box light. The system includes a mounting channel having a pair of bus bars that define positive and neutral electrical conductors for supplying electricity. Electrical modules are configured for variable positioning along the mounting channel. Each of the electrical modules includes an end cap configured to engage the mounting channel. A protrusion extends away from the end cap for insertion into the mounting channel and for securing the end cap to the mounting channel at a selected position. A pair of terminal sockets makes electrical contact with the bus bars. A socket receives and supports an electrical component, preferably an LED light stick. The socket supports electrical connections to the terminal sockets for receiving and supplying power to the electrical component.
