Suspended luminaire assembly

A luminaire assembly adapted for being suspended indoors, comprising:

• an electrical assembly having a housing with a longitudinal axis, a main housing portion, an outwardly extending lower edge portion, and a socket for receiving a lamp therein;
• and
• an optical member having an interior surface and an upper opening, the interior surface including an end wall disposed about the upper opening, the upper opening for receiving the housing through the upper opening and being coaxial with the housing, the upper opening further having a shape corresponding to the housing, wherein in a suspended orientation the housing projects from the upper opening of the optical member so that the lower edge portion is adjacent to the end wall and extends around the upper opening for retaining and suspending the optical member, and wherein in a nested orientation the main housing portion of the housing is disposed within the optical member so that the lower edge portion is distal from the upper opening.

A luminaire assembly adapted for suspension from an overhead location, comprising:

• an electrical assembly including a cylindrical housing portion and a lower flanged edge portion;
• and
• an optical member having an annular upper opening for receiving the cylindrical housing through the annular upper opening, the optical member having an interior surface having an upper end wall surrounding the upper opening, wherein in a fully extended orientation the cylindrical housing projects from the upper opening of the optical member so that the lower flanged edge portion is adjacent to and encompasses the upper opening for retaining and suspending the optical member therefrom, and wherein in a nested orientation the cylindrical housing at least partially extends within the optical member so that the lower flanged edge portion is distal from the upper opening.
