摘要

A method of retro-fitting an existing luminaire housing comprises the steps of removing lighting components from the existing housing, fastening a first powertray retaining assembly to an end cap of the existing housing, fastening a second powertray retaining assembly to a second end cap of the existing troffer, telescoping a powertray to a size allowing the powertray to be moved through an opening in the existing housing, inserting the powertray through the opening in the existing housing and retaining the powertray on one of the first and second retaining assemblies, telescoping the powertray to engage the other of the first and second retaining assemblies and, positioning a diffuser in the troffer. A retro-fit luminaire assembly is also disclosed.

1. A method of retro-fitting an existing luminaire housing comprising the steps of:
removing lighting components from said existing housing; fastening a first powertray retaining assembly to an end cap of said existing housing; fastening a second powertray retaining assembly to a second end cap of said existing housing, wherein said fastened second powertray retaining assembly is substantially parallel to the fastened first powertray retainer assembly, thereby defining a distance between said powertray retaining assemblies along a line substantially perpendicular to each of said powertray retaining assemblies; telescoping a powertray to a size allowing said powertray to be moved through an opening in said existing housing; inserting said powertray through said opening in said existing housing and retaining said powertray on one of said first and second retaining assemblies; telescoping, in a direction substantially parallel to said line, said powertray to engage the other of said first and second retaining assemblies; positioning a diffuser in said luminaire housing; and, wherein the powertray comprises a first portion and a second portion, and each of said telescoping steps comprises sliding the first portion against the second portion.
