ABSTRACT:
Apparatus for sealing the space between the outside of the socket and the reflector of an outdoor luminaire of the type having its lamp on a substantially horizontal axis. The reflector has an elongated oblong opening through which the socket projects, the oblong shape of the opening enabling setting the mounting height of the cylindrical socket. The space between the socket and reflector must be sealed to prevent insects, dust and dirt from entering the reflector. A sealing plate with an opening larger than the area of the socket circular section resiliently grips the reflector and compresses a gasket liner peripherally enclosing the reflector opening. Adhered to the plate is a second gasket which yieldably engages the outer wall of the socket with an interference fit and completes the sealing action. The resilient gripping of the reflector by the plate is accomplished by two stepped ears on the sealing plate. The spacing between the step of the ears is less than the length of the oblong opening enabling the plate to be placed on the reflector with the tabs extending through the opening so that the plate may be rotated 90.degree. to engage the tabs to the reflector across the width of the opening compressing the liner.
