Tooless cover retention and moisture protection for luminaires
A luminaire assembly comprising: a housing; a moisture intrusion guard including an orifice and at least one slot; a cover coupled to the housing, the cover comprising a retention assembly including at least one protrusion passing through at least one slot of the moisture intrusion guard, the retention assembly locking the cover to the housing.
1 . A luminaire comprising:
a housing;
a cover coupled to the housing, wherein the cover and the housing combine to form an enclosure and define a mounting opening thereinto at a rear of the luminaire for receiving a tenon;
a pliable moisture intrusion guard sheet covering the mounting opening and defining an orifice for receiving the tenon, the orifice being substantially aligned with the mounting opening, wherein the pliable moisture intrusion guard sheet includes at least one slot;
a guard retention structure including at least one protrusion passing through the at least one slot, thereby securing the pliable moisture intrusion guard sheet in the enclosure and forming a seal about the mounting opening, wherein the at least one protrusion extends from the cover.
2 . The luminaire of claim 1 , wherein the guard retention structure comprises a plurality of protrusions for passing through multiple slots of the pliable moisture intrusion guard sheet.
3 . The luminaire of claim 1 further comprising a hinge bracket for coupling with the cover.
4 . The luminaire of claim 3 , wherein the cover rotates via the hinge bracket between open and closed positions.
5 . The luminaire of claim 1 , wherein the at least one protrusion comprises a stepped architecture for passing through the at least one slot while also passing through an aperture in a base of the housing.
6 . The luminaire of claim 1 , wherein the orifice of the pliable moisture intrusion guard sheet is configured to receive a tenon with a cross-section of 1.66 inches to 2.375 inches.
7 . The luminaire of claim 1 , wherein the pliable moisture intrusion guard sheet is provided with at least one hole disposed on a lower portion of the moisture intrusion guard sheet.
8 . The luminaire of claim 1 , wherein a lower portion of the pliable moisture intrusion guard sheet includes at least one cutout.
9 . The luminaire of claim 1 , wherein the pliable moisture intrusion guard sheet is constructed of an elastic or elastomeric material.
10 . A method of installing a moisture intrusion guard sheet in a luminaire, comprising:
positioning the moisture intrusion guard sheet within a housing of the luminaire to cover a mounting opening at a rear of the luminaire for receiving a tenon;
substantially aligning the orifice in the moisture intrusion guard sheet for receiving the tenon with the mounting opening;
passing at least one protrusion extending from the cover through least one slot disposed within the moisture intrusion guard sheet;
rotating a cover and the at least one protrusion with respect to a cover retention assembly thereby closing an interior cavity of the luminaire.
11 . The method according to claim 10 , further comprising inserting a fastener through at least one hole on a lower portion of the moisture intrusion guard sheet and into a threaded or unthreaded hole disposed in the housing.
12 . The method according to claim 10 , further comprising forming a seal between the moisture intrusion guard sheet and the housing.
