The reflector flange is then held in position by a removable arc-shaped retention spring. ## Claims ### Claim 1 A removable deformable retention spring for retaining a component in a luminaire and for allowing removal of the component from the luminaire, comprising: a spring body having a shape which substantially conforms to the shape of the top surface of said component; a locking mechanism comprising one or more tabs outwardly extending from said spring body and shaped to be receivable within a tab receiving area of said luminaire; whereby one side of said retention spring may be held in contact with said top surface of said component when said retention spring is in use in said luminaire. ### Claim 2 (depends on 1) The retention spring of claim 1, wherein said spring has an arc-shaped spring body having first and second ends. ### Claim 3 (depends on 2) The retention spring of claim 2, wherein the diameter of said spring is alterable by moving said ends relative to each other. ### Claim 4 (depends on 3) The retention spring of claim 3, wherein said spring body is formed from a flat strip. ### Claim 5 (depends on 1) The retention spring of claim 1, wherein said tab receiving area is within the face of said luminaire, said face having one or more recessed annuli. ### Claim 6 (depends on 5) The retention spring of claim 5, wherein said retention spring is configured to retain a reflector received in one of said recessed annuli. ### Claim 7 (depends on 6) The retention spring of claim 6, wherein said retention spring is configured to be interposed between said top surface of said reflector and a lens. ### Claim 8 A removable deformable retention spring for retaining a component in a luminaire and for allowing removal of a component from a luminaire, comprising: a deformable spring body having a shape which substantially conforms to the shape of an outwardly extending flange on said component; a locking mechanism having opposed tabs outwardly extending from said spring body and shaped to be receivable within corresponding notches of said luminaire; whereby one side of said retention spring is designed to fit against the top surface of said flange of said component when said retention spring is in use in said luminaire. ### Claim 9 (depends on 8) The retention spring of claim 8, wherein said spring has an arc-shaped spring body having first and second ends. ### Claim 10 (depends on 9) The retention spring of claim 9, wherein the diameter of said spring is alterable by moving said ends relative to each other. ### Claim 11 (depends on 8) The retention spring of claim 8, wherein said spring has first and second ends and wherein a dimension of said spring is alterable by moving said ends relative to each other. ### Claim 12 (depends on 11) The retention spring of claim 11, wherein said notches are within the face of said luminaire, said face having two recessed annuli. ### Claim 13 (depends on 12) The retention spring of claim 12, wherein said retention spring is in contact with a reflector flange resting in one of said two recessed annuli. ### Claim 14 (depends on 13) The retention spring of claim 13, wherein said notches are adjacent said annulus. ### Claim 15 (depends on 14) The retention spring of claim 14, wherein said retention spring is interposed between said reflector flange and a lens secured in the remaining of said two recessed annuli. ### Claim 16 A removable deformable retention spring for retaining a component in a luminaire and for allowing removal of a component from a luminaire, comprising: a deformable flat spring body having a shape which substantially conforms to the shape of an outwardly extending flange on a component; said spring body having first and second ends wherein a dimension of said spring may be altered by moving said ends relative to each other; a locking mechanism comprising first and second opposed tabs outwardly extending from said spring body and shaped to be receivable and secured within a first and second notch of said luminaire; whereby one side of said retention spring is designed to fit against the top surface of said flange of said component when said retention spring is in use in said luminaire. ### Claim 17 (depends on 16) The retention spring of claim 16, wherein said spring is an arc-shaped spring having an alterable diameter. ### Claim 18 (depends on 16) The retention spring of claim 16, wherein said first and second notch are within the face of said luminaire, said face having two recessed annuli. ### Claim 19 (depends on 18) The retention spring of claim 18, wherein said retention spring retains a reflector in a first of said one or more recessed annuli. ### Claim 20 (depends on 19) The retention spring of claim 19, wherein said retention spring is in contact with a reflector flange resting in the first of two recessed annuli and retains said reflector flange flush against said first annulus. ### Claim 21 (depends on 20) The retention spring of claim 20, wherein said retention spring is interposed between said reflector flange and a lens secured in the second of said two recessed annuli.
