## Abstract

Systems are provided for a frame of an optic element of a lighting system. In one example, a baffle frame including extended exterior sidewalls and inner angled walls extending below a bottom surface of the optic element may reduce light reflecting off a workpiece and escaping outside and interior of the baffle frame.

## Claims

### Claim 1

A lighting system, comprising:
a light source;
a coupling optic element positioned between the light source and a workpiece to be cured by light from the light source; and
a frame coupled to an exterior, top surface of the coupling optic element, the frame including vertical sidewalls extending to a point below or in level with an exterior, bottom surface of the coupling optic element and angled sidewalls angled from the point and partially vertically toward the coupling optic element,
wherein the frame includes a central, concave, inner surface formed along a length of the frame and adapted to receive the coupling optic element, the inner surface in face-sharing contact with the exterior, top surface of the coupling optic element.

### Claim 2 (depends on 1)

The lighting system of claim 1, wherein the light source is a light emitting device; and
wherein the light source is positioned above the frame, at a top, open surface of the frame,
the top, open surface of the frame being a window frame allowing light to pass from the light source to the coupling optic element.

### Claim 3 (depends on 2)

The lighting system of claim 2, wherein the angled sidewalls are angled inward toward a side of the coupling optic element along a mid-section of the coupling optic element, the coupling optic element including one or more of a rod lens, a cylindrical lens, a Fresnel lens, or flat glass.

### Claim 4 (depends on 1)

The lighting system of claim 1, wherein the frame further comprises bottom sidewalls that extend horizontally, in a direction perpendicular to the vertical sidewalls, each sidewall of the bottom sidewalls extending from one of the vertical sidewalls to one of the angled sidewalls.

### Claim 5 (depends on 4)

The lighting system of claim 4, wherein the frame at least partially comprises a black anodized material and wherein one or more of the angled sidewalls and the bottom sidewalls includes one or more of grooves and surface texturing, the one or more grooves extending from an exterior surface of the one of more angled sidewalls into an interior of the frame or extending from an exterior surface of the bottom surface and into the interior of the frame.

### Claim 6 (depends on 1)

The lighting system of claim 1, further comprising a dispenser mechanism containing photosensitive material arranged proximate to the frame.

### Claim 7 (depends on 1)

The lighting system of claim 1, wherein a curvature of the inner surface matches a curvature of the exterior surface of the coupling optic element, the coupling optic element being cylindrical.
