A modular vapor-tight light fixture is provided herein which generally includes first and second vapor-tight light modules, and a coupling for connecting the first and second vapor-tight light modules. Each of the vapor-tight light modules includes: a channel housing; a lens secured to the channel housing; a plurality of solid state light generating elements; and, first and second end caps. Each of the channel housings includes first and second rails which each define a mounting channel. The coupling includes mounting strip portions configured such that, with the first and second vapor-tight light modules being adjacent, the mounting strip portions are simultaneously received in the mounting channels of both the first and second vapor-tight light modules. Advantageously, with the subject invention, fully enclosed vapor-tight light modules may be provided at shorter lengths which are connected by the coupling to provide a fixture comparable in length to prior-art vapor-tight light fixtures.

An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position.

A spine for a troffer light fixture is provided. The spine is configured to receive omni-directional LED bulbs. The spine comprises: a base, a first wall, a second wall, and first end walls defining a light chamber shaped as a trough. Interior angles between the first wall, second wall, and base is 90-100 degrees respectively. The second wall defines a plurality of apertures each having a central axis arranged generally parallel in a linear arrangement. The apertures include: a pair of flanking apertures, the axis of each flanking aperture positioned 80-110 mm from one of the first end walls, and at least one interior aperture, the axis of each interior aperture positioned 135-145 mm from the axis of an adjacent aperture. Each of the plurality of apertures provides an opening through which an omni-directional LED bulb can extend parallel to the base to engage a socket mounted on the spine.

A lighting apparatus comprises an outer housing and a lamp mounting region comprising a support. At least one linear LED lamp has first and second end connectors at opposite ends, and each of the end connectors has a housing defining an opening. First and second support connectors have an integral mounting base configured to couple to the support and a second portion configured to be insertable through a respective one of the openings as an incident of the linear LED lamp moving relative to the support connectors from a position fully separated from the support connectors in a path that is transverse to the length of the body into an engaged position. The second portion of each support connector has a second surface configured to be placed into confronting relationship with a corresponding first surface of the corresponding end connector to prevent separation of the support connector and the end connector with the second portion of the support connector residing within the housing of the end connector in the engaged position.

A bracket assembly is described. A center bracket may have two protrusions on a first leg portion and two protrusions on a second leg portion. The protrusions of the center bracket may be positioned and shaped to interface with arcuate guide slots on leg portions of a first bracket and a second bracket. Curvatures of the arcuate guide slots may be positioned and shaped to maintain the center bracket longitudinal axis at substantially the same angle with respect to the first bracket longitudinal axis as the center bracket longitudinal axis is with respect to the second bracket longitudinal axis as the first bracket and second bracket pivot over a range of angles about a point of rotation in an assembled configuration.
