The engagement system can also include a bracket configured to be detachably coupled to the engagement component, where the bracket includes a bracket body, a first additional component coupling feature, and a second additional component coupling feature, where the bracket body includes an engagement component receiving feature that is configured to engage the first and second bracket engagement extensions, and where the engagement component is able to couple to and decouple from the bracket when the first and second bracket engagement extensions are moved with respect to the engagement component body. ## Claims ### Claim 1 An engagement system for a recessed luminaire, the engagement system comprising: an engagement component comprising an engagement component body, a first bracket engagement extension that extends from a first portion of the engagement component body, and a second bracket engagement extension that extends from a second portion of the engagement component body, wherein the first bracket engagement extension and the second bracket engagement extension are movable with respect to the engagement component body; a bracket configured to be detachably coupled to the engagement component, wherein the bracket comprises a bracket body, a first additional component coupling feature that extends from a first portion of the bracket body, and a second additional component coupling feature that extends from a second portion of the bracket body, wherein the bracket body comprises an engagement component receiving feature that is configured to engage the first bracket engagement extension and the second bracket engagement extension, and wherein the engagement component is configured to couple to and decouple from the bracket when the first bracket engagement extension and the second bracket engagement extension are moved with respect to the engagement component body; and wherein the bracket further comprises a support extension that extends from the bracket body substantially parallel to the first additional component coupling feature and the second additional component coupling feature, and wherein the support extension is configured to abut against a top plate of a housing of the recessed luminaire. ### Claim 2 (depends on 1) The engagement system of claim 1, wherein the engagement component comprises a U-shaped flat spring. ### Claim 3 (depends on 1) The engagement system of claim 1, wherein the bracket is U-shaped, and wherein the bracket is substantially rigid. ### Claim 4 (depends on 1) The engagement system of claim 1, wherein the first engagement component receiving feature and a second engagement component receiving feature of the bracket body comprises apertures that traverse a thickness of the bracket body. ### Claim 5 (depends on 1) The engagement system of claim 1, wherein the engagement component body of the engagement component comprises a coupling feature that is configured to couple to a driver compartment of the recessed luminaire. ### Claim 6 (depends on 5) The engagement system of claim 5, wherein the bracket body of the bracket has an aperture that traverses therethrough, wherein the aperture aligns with the coupling feature of the engagement component body when the engagement component is coupled to the bracket. ### Claim 7 An engagement system for a recessed luminaire, the engagement system comprising: an engagement component comprising an engagement component body, a first bracket engagement extension that extends from a first portion of the engagement component body, and a second bracket engagement extension that extends from a second portion of the engagement component body, wherein the first bracket engagement extension and the second bracket engagement extension are movable with respect to the engagement component body; and a bracket configured to be detachably coupled to the engagement component, wherein the bracket comprises a bracket body, a first additional component coupling feature that extends from a first portion of the bracket body, and a second additional component coupling feature that extends from a second portion of the bracket body, wherein the bracket body comprises an engagement component receiving feature that is configured to engage the first bracket engagement extension and the second bracket engagement extension, and wherein the engagement component is configured to couple to and decouple from the bracket when the first bracket engagement extension and the second bracket engagement extension are moved with respect to the engagement component body, wherein the first engagement component receiving feature is formed by peeling back a part of the bracket body in a downward direction. ### Claim 8 A recessed luminaire comprising: a driver compartment that houses a driver, wherein the driver compartment comprises a first coupling feature along a bottom surface; and an engagement system comprising: an engagement component comprising an engagement component body, a first bracket engagement extension that extends from a first portion of the engagement component body, and a second bracket engagement extension that extends from a second portion of the engagement component body, wherein the first bracket engagement extension and the second bracket engagement extension are movable with respect to the engagement component body, and wherein the engagement component body comprises a second coupling feature that complements the first coupling feature of the driver compartment; and a bracket configured to be detachably coupled to the engagement component, wherein the bracket comprises a bracket body, a first additional component coupling feature that extends from a first portion of the bracket body, and a second additional component coupling feature that extends from a second portion of the bracket body, wherein the bracket body comprises an engagement component receiving feature that is configured to engage the first bracket engagement extension and the second bracket engagement extension, wherein the engagement component is able to couple to and decouple from the bracket when the first bracket engagement extension and the second bracket engagement extension are moved with respect to the engagement component body; and wherein the bracket further comprises a support extension that extends from the bracket body substantially parallel to the first additional component coupling feature and the second additional component coupling feature, and wherein the support extension is configured to abut against a top plate of a housing of the recessed luminaire. ### Claim 9 (depends on 8) The recessed luminaire of claim 8, further comprising: a top plate of a lighting assembly, wherein the top plate comprises a first bracket coupling feature and a second bracket coupling feature, wherein the first bracket coupling feature is configured to couple to the first additional component coupling feature, and wherein the second bracket coupling feature is configured to couple to the second additional component coupling feature. ### Claim 10 (depends on 9) The recessed luminaire of claim 9, wherein the first additional component coupling feature comprises a slot that traverses a first extension of the bracket, and wherein the second additional component coupling feature comprises a curved distal end of a second extension of the bracket. ### Claim 11 (depends on 8) The recessed luminaire of claim 8, wherein the first bracket engagement extension and the second bracket engagement extension are accessible under the bracket when the engagement component is coupled to the bracket. ### Claim 12 (depends on 8) The recessed luminaire of claim 8, wherein the first additional component coupling feature and the second additional component coupling feature of the bracket are configured to couple to a structure to which the engagement system is mounted. ### Claim 13 (depends on 12) The recessed luminaire of claim 12, wherein the structure comprises a frame of the recessed luminaire. ### Claim 14 (depends on 8) The recessed luminaire of claim 8, further comprising: a junction box that houses the driver compartment, wherein a bottom wall of the junction box has an aperture that traverses therethrough, wherein the engagement component passes through the aperture when the driver compartment is inserted into or removed from the junction box.
