摘要 |
A door frame hingeably mounted to a lensed fluorescent troffer lighting fixture and carrying a prismatic lens cover, the door frame also integrally provides a light trap function. Structural components of the door frame have fastening elements formed integrally therewith for attachment of said components together without the use of separate fastening elements. The door frame includes low profile latching structure which allows ready opening of the door frame for relamping or other maintenance functions, hinge elements acting not only to hold the door frame to the light fixture but also to hold the door frame in a fully open position. The door frame further acts to impart rigidity to the lighting fixture when in a closed position.
