## Abstract

A curved recessed supporting device is provided for installation of LED illuminating devices comprising a curved main channel section, shorter open-top end modules securable to a first end of the channel section, and an elongated lens securable over the top of the channel section. Flanges extending from the bottom of the channel section are secured to a wall stud or ceiling joist and end modules are secured to the ends of the channel section. LED strips are secured onto the spaced apart sidewalls inside the channel section and connected to appropriate wiring through one of the end modules. A channel cap is secured across the top of the end modules and foam inserted into the channel section. Drywall is laid to the edges of the device, is spackled and painted. The foam is removed and the lens secured over the channel section.

## Claims

### Claim 1

A curved recessed supporting device for installation of LED illuminating devices, comprising:
an elongated curved main channel section, comprising:
a first bottom;
first and second spaced apart sidewalls, each extending perpendicularly from opposite sides of the first bottom and each having a groove in a top edge;
at least one pair of first bottom clips extending outward from the first bottom beyond the first and second sidewalls; and
first and second top flanges, each having a curve equal to the curve of the main channel section, the first top flange insertable into the groove of the first sidewall and extending perpendicularly outward from the first sidewall, and the second top flange insertable into the groove of the second sidewall and extending perpendicularly outward from the second sidewall, whereby when the first and second top flanges are inserted in the grooves of the first and second sidewalls, a distance between outer edges of the first and second top flanges is substantially equal to a distance between outer edges of the first pair of bottom clips;
a first elongated open-top end module, shorter than the main channel section and securable at a first end to a first end of the main channel section, the first end module comprising:
a second bottom;
third and fourth spaced apart sidewalls, each extending perpendicularly from opposite sides of the second bottom and each having a groove in a top edge;
at least one second pair of bottom clips extending outward from the second bottom beyond the third and fourth sidewalls; and
a planar top cap having a width substantially equal to a distance between outer edges of the second pair of bottom clips, the top cap further having a third pair of spaced apart flanges extending perpendicularly from a bottom surface of the top cap, the third pair of flanges being insertable into the grooves in the top edges of the third and fourth sidewalls; and
an elongated lens securable between the first and second sidewalls of the main channel section.

### Claim 2 (depends on 1)

The curved recessed supporting device of claim 1, further comprising a second elongated open-top end module securable to a second end of the main channel section.

### Claim 3 (depends on 1)

The curved recessed supporting device of claim 1, wherein the main channel section is formed from aluminum.

### Claim 4 (depends on 1)

The curved recessed supporting device of claim 1, wherein the main channel section is formed as a single piece.

### Claim 5 (depends on 1)

The curved recessed supporting device of claim 1, wherein the top flanges are formed from polyvinyl chloride (PVC).

### Claim 6 (depends on 1)

The curved recessed supporting device of claim 1, wherein the lens is formed from a flexible material.

### Claim 7 (depends on 1)

The curved recessed supporting device of claim 1, further comprising a pair of T-shaped connectors securable between the first end module and the first end of the main channel section.

### Claim 8 (depends on 1)

The curved recessed supporting device of claim 1, wherein the first end module further comprises an end cap securable to a second end of the first end module.

### Claim 9

A method of installing curved LED illuminating devices, comprising:
placing an elongated curved main channel section against a wall stud or ceiling joist, the main channel section having a first bottom and first and second spaced apart sidewalls extending perpendicularly from opposite sides of the first bottom;
securing first bottom clips between the main channel section and the wall stud or ceiling joist, the first bottom clips extending outward from a bottom of the main channel section perpendicular to the first and second sidewalls;
securing first and second top flanges to top edges of the first and second sidewalls, respectively, the first and second top flanges extending outward perpendicular to the first and second sidewalls;
securing a first end of a first end module to a first end of the main channel section, the first end module having a second bottom and third and fourth spaced apart sidewalls;
securing second bottom clips to the wall stud or ceiling joist, the second bottom clips extending outward from the second bottom of the first end module;
securing LED strips to the insides of the first and second spaced apart sidewalls of the main channel section;
extending an electric cable through the first end module;
connecting the electric cable to an end of the LED strip;
securing a channel cap across top edges of the third and fourth sidewalls of the first end module, the channel cap extending beyond the third and fourth sidewalls;
temporarily inserting foam into space in the main channel section between the first and second sidewalls;
laying drywall to edges of the main channel section and the first end module;
painting and spackling the drywall;
removing the foam from the main channel section; and
securing a lens over the main channel section between the first and second sidewalls.

### Claim 10 (depends on 9)

The method of claim 9, further comprising securing an end cap to a second end of the first end module.

### Claim 11 (depends on 9)

The method of claim 9, further comprising securing a first end of a second end module to a second end of the main channel section after securing the first end module to the first end of the main channel section.

### Claim 12 (depends on 9)

The method of claim 9, further comprising, after securing the LED strips to the sides of the main channel section, placing any extra length of the LED strip in the first end module.

### Claim 13 (depends on 9)

The method of claim 9, further comprising, before securing the first and second top flanges to the sidewalls, bending the first and second top flanges to a curvature corresponding to a curvature of the main channel section.

### Claim 14 (depends on 9)

The method of claim 9, further comprising, before securing the lens over the main channel section, bending lens to a curvature corresponding to a curvature of the main channel section.

### Claim 15 (depends on 9)

The method of claim 9, further comprising, after securing the LED strips to the insides of the first and second sidewalls, placing in the first end module lengths of the LED strips longer than a length of the main channel section.

### Claim 16 (depends on 9)

The method of claim 9, further comprising securing an end cap to a second end of the first end module.

### Claim 17 (depends on 1)

The method of claim 1, further comprising securing the first end module with the first end of the main channel section with a pair of T-shaped connectors.
