The invention relates also to an assembly unit where the alcove is formed as a stepped bottom where a mating recess forms the deepest bottom part, a support recess forms the middle bottom part and the alcove bottom forms an upper bottom part. ## Claims ### Claim 1 A light fixture comprising: a light source arranged in a lamp housing; the lamp housing comprising a housing shell forming a cavity wherein the light source is arranged and configured to emit light out of the lamp housing, the lamp housing comprises an attachment assembly comprising an alcove formed in an outer surface of the housing shell, wherein the alcove is configured to accommodate a fastening unit, the fastening unit is configured to receive a mating member connected to a support structure and the mating member can be locked to the fastening unit, and wherein the fastening unit comprises a locking plate and a top plate and where the locking plate is arranged below the top plate and includes a locking member configured to lock with the mating member. ### Claim 2 (depends on 1) The light fixture of claim 1, wherein the alcove comprises a mating recess formed in a bottom part thereof, where the mating recess is configured to receive at least a part of the mating member. ### Claim 3 (depends on 1) The light fixture of claim 1, wherein the alcove comprises a support recess formed in a bottom part thereof, where the support recess is configured to accommodate the locking plate. ### Claim 4 (depends on 3) The light fixture of claim 3, wherein a mating recess is formed in a bottom part of the support recess. ### Claim 5 (depends on 1) The light fixture of claim 1, wherein the fastening unit comprises a quarter turn lock. ### Claim 6 (depends on 1) The light fixture of claim 1, wherein the housing shell is formed as a polymer housing shell and the fastening unit is secured to the polymer housing shell by a self-tapping screw configured to be drilled into a part of the polymer housing shell. ### Claim 7 (depends on 1) The light fixture of claim 1, wherein the fastening unit is formed as a fastening plate configured to fit into the alcove such that side walls of the alcove support the fastening plate. ### Claim 8 (depends on 1) The light fixture of claim 1, wherein a depth of the alcove is configured to accommodate the fastening unit such that the fastening unit is entirely kept inside the alcove. ### Claim 9 (depends on 1) The light fixture of claim 1, wherein the alcove is provided as a recess in a polymer housing shell and a surface of the polymer housing shell and a surface of a fastening unit forms a flat surface. ### Claim 10 (depends on 9) The light fixture of claim 9, wherein the alcove is configured to partially protrude from the surface of the polymer housing shell. ### Claim 11 (depends on 1) A light fixture system comprising the light fixture of claim 1 and at least one support structure comprising the mating member. ### Claim 12 (depends on 11) The light fixture system of claim 11 wherein the mating member comprises a locking rod configured to lock with the fastening unit upon rotation of the locking rod. ### Claim 13 (depends on 11) The light fixture system of claim 11, wherein the mating member is formed as a bolt and the fastening unit comprises a threaded hole wherein the bolt can be screwed. ### Claim 14 (depends on 11) The light fixture system of claim 11, wherein the at least one support structure is formed as a standard omega bracket and the lamp housing comprises two attachment assemblies arranged at a mutual distance enabling the light fixture to be stitched to the standard omega bracket. ### Claim 15 A light fixture comprising: a lamp housing including an attachment assembly and a housing shell that forms a cavity, wherein the attachment assembly includes an alcove formed in an outer surface of the housing shell to accommodate a fastening unit, a light source arranged in the lamp housing and being configured to emit light; and a mating member for being received by the fastening unit and being connected to a support structure that locks the mating member to the fastening unit, wherein the fastening unit comprises a locking plate and a top plate and wherein the locking plate is arranged below the top plate and includes a locking member configured to lock with the mating member. ### Claim 16 (depends on 15) The light fixture of claim 15, wherein the alcove comprises a mating recess formed in a bottom part thereof, wherein the mating recess is configured to receive at least a part of the mating member. ### Claim 17 (depends on 15) The light fixture of claim 15, wherein the alcove comprises a support recess formed in a bottom part thereof, where the support recess is configured to accommodate the locking plate. ### Claim 18 A light fixture comprising: a light source; a lamp housing including an attachment assembly, a housing shell that forms a cavity, and the light source, wherein the attachment assembly includes an alcove formed in an outer surface of the housing shell to accommodate a fastening unit; a mating member for being received by the fastening unit and being connected to a support structure that locks the mating member to the fastening unit; and wherein the fastening unit comprises a locking plate and a top plate and where the locking plate is arranged below the top plate and includes a locking member configured to lock with the mating member.
