The lighting assembly includes a ceiling pan for mounting to the ceiling support and a lamp assembly attached to the ceiling pan. The lamp assembly is adjustable in a transverse and rotational direction with respect to the ceiling pan. A stop member on the ceiling pan is received in an aperture in the lamp assembly to limit movement of the lamp assembly on the base. The lamp assembly is provided with alignment springs to align the lamp assembly at predetermined settings. A sight window is formed in the ceiling to visually set the lamp assembly in a selected position. A locking member on the lamp assembly locks the lamp assembly in a fixed position on the ceiling pan. ## Claims ### Claim 1 A light assembly comprising: a ceiling pan adapted for attaching to a ceiling, said ceiling pan having an opening for directing light in a downward direction; and a lamp assembly mounted on said ceiling pan, and having a base and a lamp for directing light in a substantially downward direction through said opening in said ceiling pan, said base being coupled to said pan for limited rotational movement about a vertical axis with respect to said ceiling pan and for limited transverse movement with respect to said pan. ### Claim 2 (depends on 1) The lighting assembly of claim 1, further comprising a plurality of spaced-apart hold down members coupled to said ceiling pan, each of said hold down members having an end overlying said base of said lamp assembly. ### Claim 3 (depends on 2) The lighting assembly of claim 2, further comprising a locking member coupled to said base and being movable to a locking position to engage said ceiling pan and move said base into engagement with said hold down members. ### Claim 4 (depends on 3) The lighting assembly of claim 3, wherein said locking member includes a pivotable cam having a cam member for engaging a locking spring, said locking spring having an end for engaging said base. ### Claim 5 (depends on 4) The lighting assembly of claim 4, wherein said locking spring has a detent for engaging said cam member. ### Claim 6 (depends on 1) The lighting assembly of claim 1, said ceiling further comprising a stop member for engaging said lamp assembly for limiting rotational movement of said lamp assembly with respect to said ceiling pan. ### Claim 7 (depends on 6) The lighting assembly of claim 6, wherein said base includes an aperture for receiving said stop member. ### Claim 8 (depends on 7) The lighting assembly of claim 7, wherein said stop member is a pin extending upwardly through said aperture and being fixed to said ceiling pan to limit rotational and transverse movement of said lamp assembly. ### Claim 9 (depends on 6) The lighting assembly of claim 6, wherein said lamp assembly further comprises a lamp support for supporting said lamp, wherein said lamp support is adjustable about a vertical axis and about a horizontal axis to direct the light through said opening in said base to the target area. ### Claim 10 (depends on 1) The lighting assembly of claim 1, wherein said lamp assembly has a downwardly extending sleeve, said sleeve extending through said opening in said ceiling pan and having a dimension less than said opening to allow transverse adjustment of said lamp assembly with respect to said ceiling pan. ### Claim 11 A lighting assembly comprising: a ceiling pan for coupling to a support, said ceiling pan having a substantially planar bottom wall and having an opening extending therethrough; at least one hold down member on a top surface of said ceiling pan; a lamp assembly having a base secured to said ceiling pan by said at least one hold down member, said base having an opening aligned with said opening in said pan, and a lamp coupled to said base and for directing light downwardly through said opening in said ceiling pan and said base of said lamp assembly, said lamp assembly being rotatably and transversely movable with respect to said ceiling pan; and a stop assembly for limiting rotational and transverse movement of said lamp assembly with respect to said ceiling pan. ### Claim 12 (depends on 11) The lighting assembly of claim 11, further comprising a plurality of said hold down members spaced apart around said opening in said ceiling pan, each of said hold down members having an end overlying said bottom wall of said ceiling pan. ### Claim 13 (depends on 11) The lighting assembly of claim 11, wherein said stop assembly comprises a stop member on said ceiling pan for contacting said lamp assembly to limit rotational and transverse movement of said lamp assembly. ### Claim 14 (depends on 11) The lighting assembly of claim 11, wherein said stop assembly comprises a stop member extending upwardly from and fixed to said bottom wall of said ceiling pan; and an aperture in said base adapted for receiving said stop member, said aperture having a dimension to allow limited transverse and rotational movement of said lamp assembly. ### Claim 15 (depends on 11) The lighting assembly of claim 11, wherein said base of said lamp assembly has a plurality of glide members between said base and said bottom wall of said ceiling pan. ### Claim 16 (depends on 15) The lighting assembly of claim 15, wherein said glide members extend downwardly from said base. ### Claim 17 (depends on 15) The lighting assembly of claim 15, wherein said glide members are detents extending downwardly from a bottom surface of said base and are integrally formed with said base. ### Claim 18 (depends on 11) The lighting assembly of claim 11, wherein said ceiling pan includes at least one sight window in said bottom wall for visually aligning said lamp assembly in a predetermined position. ### Claim 19 (depends on 18) The lighting assembly of claim 18, wherein said base of said lamp assembly includes an indicator that is visible through said sight window when said lamp assembly is in said predetermined position. ### Claim 20 (depends on 19) The lighting assembly of claim 19, further comprising a spring member overlying said base and having a downwardly extending detent; and wherein said indicator is an aperture in said base with a dimension to receive said detent to hold said lamp assembly in said predetermined position. ### Claim 21 A lighting assembly comprising: a ceiling pan having a top surface, a bottom surface, and a centrally located opening for directing light in a substantially downward direction; a lamp assembly on said top surface of said ceiling pan, said lamp assembly having a base contacting said top surface of said ceiling pan, a lamp assembly coupled to said base; and a locking assembly for locking said lamp assembly in a fixed position with respect to said pan. ### Claim 22 (depends on 21) The lighting assembly of claim 21, wherein said locking assembly comprises a locking arm pivotally coupled to said base of said lamp assembly; and a break member coupled to said base for contacting said ceiling pan, said break member being actuated by said locking arm. ### Claim 23 (depends on 22) The lighting assembly of claim 22, wherein said locking arm includes a cam member for engaging said break member. ### Claim 24 (depends on 23) The lighting assembly of claim 23, wherein said break member is a spring having a first end coupled to said base and second fee end for engaging said ceiling pan, and where said spring has a detent between said first and second ends for engaging said cam member on said locking arm.
