## Abstract

A path light having a shaped pathway of projected light that minimizes distracting illumination of the vertical leg of the luminaire with a shaped mask over the light source. The mask forms shaped shadows that guide the light around the support leg and onto the desired pathway.

## Claims

### Claim 1

A path light that comprises: (a) a horizontally extended member that comprises a light source within a chamber and that can project light through a downwardly directed opening in said chamber, (b) a vertically extended member that elevates said horizontally extended member, and (c) a generally rectangular projection mask partially obstructing said opening to obstruct light from said light source from falling on said vertically extended member, wherein said projection mask exhibits an opening that can be positioned under said light source of said chamber to partially obstruct light from said light source, said projection mask exhibiting a first shape that is positioned under said light source to form a shadow in projected light that is wider across said chamber in a rear portion thereof than a front portion thereof.

### Claim 2 (depends on 1)

A path light according to claim 1 wherein said horizontally extended member is shorter than said vertically expended member.

### Claim 3 (depends on 2)

A path light according to claim 2 wherein said horizontally extended member and said vertically extended member form an L-shape that projects light downwardly.

### Claim 4 (depends on 1)

A path light according to claim 1 wherein said mask further comprises a second shape that is not directly under said light source and which forms a shadow in projected light from said chamber that is wider across said chamber in a rear portion thereof than a front portion thereof.
