Abstract
Abstract Outdoor luminaires are frequently equipped with photoelectric sensing elements to control the operation of the luminaire as a result of the ambient light conditions about the luminaire. The sensing elements are mounted and then oriented toward the north to ensure proper operation. To effect this mounting which allows angular setting of the element, the element is mounted in a mounting receptacle having a cylindrical body designed to fit within a cylindrical aperture in a mounting surface. A push-on spring, of the type known and sold under the trademark ''''Speed Nut,'''' is secured onto the receptacle wall to affix the receptacle to the mounting surface in a manner allowing angular setting of the receptacle element.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
In a luminaire housing, a receptacle for supporting a photoelectric cell actively exposed to the ambient light comprising a mounting body enclosing said cell and exposing the one end thereof, a peripheral skirt portion of said receptacle extending axially outwardly and downwardly of said body, an opening in the top surface of said housing for receiving therein said receptacle, a cylindrical step wall in said surface surrounding said opening, said skirt portion normally resting on said surface outwardly of said step wall in a mutually positioning relationship, and a push-on spring fastener surrounding said receptacle body, said fastener having resilient grasping fingers bearing against said body to permit angular movement of said body relative to said housing, said fastener resting within said step wall to hold said receptacle tightly against said housing top surface.
Claim 2
Dependent Claim
134 words
In a luminaire housing, a receptacle for supporting a photoelectric cell actively exposed to the ambient light comprising a mounting body enclosing said cell and exposing the one end thereof, a peripheral skirt portion of said receptacle extending axially outwardly and downwardly of said body, an opening in the top surface of said housing for receiving therein said receptacle, a cylindrical step wall in said surface surrounding said opening, said skirt portion normally resting on said surface outwardly of said step wall in a mutually positioning relationship, and a push-on spring fastener surrounding said receptacle body, said fastener having resilient grasping fingers bearing against said body to permit angular movement of said body relative to said housing, said fastener resting within said step wall to hold said receptacle tightly against said housing top surface.
Claim 3
Dependent Claim
150 words
In a luminaire housing having a generally horizontal top wall, a receptacle for supporting a photoelectric cell actively exposed to the ambient light, said receptacle including a body portion enclosing said cell and exposing one end thereof, a flanged cover of said receptacle extending outwardly of said body portion parallel to the axis thereof and encircling said cell and body, a generally circular opening in the top wall of said housing for receiving therein said body, a cylindrically stepped wall in said housing outwardly of said opening for mating with said flange to hold said receptacle against lateral and downward movement, and a push-on spring fastener surrounding said body and nesting within the stepped wall inner members on said fastener and grasping the body of said receptacle to hold said receptacle against upward movement out of said opening, while allowing limited angular movement of said receptacle relative to said housing.
Claim 4
Dependent Claim
150 words
In a luminaire housing having a generally horizontal top wall, a receptacle for supporting a photoelectric cell actively exposed to the ambient light, said receptacle including a body portion enclosing said cell and exposing one end thereof, a flanged cover of said receptacle extending outwardly of said body portion parallel to the axis thereof and encircling said cell and body, a generally circular opening in the top wall of said housing for receiving therein said body, a cylindrically stepped wall in said housing outwardly of said opening for mating with said flange to hold said receptacle against lateral and downward movement, and a push-on spring fastener surrounding said body and nesting within the stepped wall inner members on said fastener and grasping the body of said receptacle to hold said receptacle against upward movement out of said opening, while allowing limited angular movement of said receptacle relative to said housing.
