2. The system of claim 1 wherein:
the arcuate portion of the profile of the upper row extrusion is adjacent to the arcuate portion of the profile of the lower row extrusion.
3. The system of claim 2 in an installed condition wherein:
a skimcoat covers a junction of the ceiling drywall and the upper row extrusion.
4. The system of claim 3 further comprising:
a spacer row spanning between the lower row extrusion and the mounting extrusion.
5. The system of claim 4 , wherein the spacer row is secured to the lower row extrusion via a projection backlocked in a slot.
6. The system of claim 1 , further comprising:
a clip holding the upper row extrusion to the lower row extrusion.
7. The system of claim 6 wherein:
the clip has an extruded channel section and a set screw extending through a base portion of the channel to contact the associated upper row extrusion and the associated lower row extrusion.
8. The system of claim 1 further comprising:
a clip configured to hold a row of adjacent upper row extrusions or lower row extrusions to each other and comprising:
a main body portion spanning a junction between said adjacent extrusions; and
at each respective side of the main body portion, a pair of legs with each leg separated from its adjacent leg by a gap so as to allow the legs to flex relative to the main body portion independently.
9. The system of claim 1 , wherein at least one of the mounting extrusion, the upper row extrusion, and the lower row extrusion is are a metallic extrusion.
10. The system of claim 1 , wherein the extrusions of the transition comprise, in profile:
one or more support webs protruding from a convex side of the arcuate portion for supporting the respective extrusion against a support surface.
11. The system of claim 10 wherein:
the one or more support webs are L-shaped.
12. The system of claim 11 in an installed condition wherein:
a screw secures the extrusions to the support surface.
13. The system of claim 1 , wherein the fixture comprises:
a gear tray carried by the mounting extrusion.
14. The system of claim 13 , wherein the fixture further comprises:
a trim extrusion mounted to the mounting extrusion.
15. The system of claim 14 , wherein the trim extrusion comprises:
a rearwardly divergent edge portion.
16. The system of claim 1 , wherein the mounting extrusion and the extrusion of the transition are formed by an extrusion process.
17. A method for installing a lighting system for mounting adjacent a junction of a wall and a ceiling of a room, the system comprising a lighting fixture mountable along the wall and comprising a mounting extrusion, and a transition presenting a concave transition facing into an interior of the room and formed by an extrusion interfitting with the mounting extrusion, the method comprising:
installing a first said extrusion to a room; and
installing a second said extrusion end-to-end with the installed first extrusion via a snap engagement with a portion of a clip protruding from the end of the first extrusion.
18. The system of claim 17 , wherein the mounting extrusion and the extrusion interfitting with the mounting extrusion are formed by an extrusion process.
19. A method for installing a lighting system for mounting adjacent a junction of a wall and a ceiling of a room, the system comprising a lighting fixture mountable along the wall and comprising a mounting extrusion, and a transition presenting a concave transition facing into an interior of the room and formed by an extrusion interfitting with the mounting extrusion, the method comprising:
installing a first said extrusion to a second said extrusion via sliding a channel-sectioned clip over mated web portions of the first extrusion and the second extrusion.
20. The system of claim 19 , wherein the mounting extrusion and the extrusion interfitting with the mounting extrusion are formed by an extrusion process.
21. A lighting system for mounting adjacent a junction of a wall and a ceiling of a room, the system comprising:
a lighting fixture mountable along the wall and comprising a mounting extrusion; and
a transition presenting a concave transition facing into an interior of the room and formed by an extrusion interfitting with the mounting extrusion;
wherein the extrusion of the transition comprises:
an upper row extrusion; and
a lower row extrusion;
wherein the system further comprises:
a clip holding the upper row extrusion to the lower row extrusion.
22. The system of claim 21 , wherein the mounting extrusion and the extrusion of the transition are formed by an extrusion process.
23. A lighting system for mounting adjacent a junction of a wall and a ceiling of a room, the system comprising:
a lighting fixture mountable along the wall and comprising a mounting extrusion; and
a transition presenting a concave transition facing into an interior of the room and formed by an extrusion interfitting with the mounting extrusion;
wherein the extrusion of the transition comprises:
an upper row extrusion; and
a lower row extrusion;
wherein the system further comprises:
a clip configured to hold a row of adjacent upper row extrusions or lower row extrusions to each other and comprising:
a main body portion spanning a junction between said adjacent extrusions; and
at each respective side of the main body portion, a pair of legs with each leg separated from its adjacent leg by a gap so as to allow the legs to flex relative to the main body portion independently.
24. The system of claim 23 , wherein the mounting extrusion and the extrusion of the transition are formed by an extrusion process.
