Patent ID: 8118456

Claim:
A luminaire to illuminate surfaces, the luminaire comprising: a housing having a bottom surface and a top surface that has two sloped portions that each slope toward the bottom surface from an intermediate portion therebetween, the housing including an interior and at least one window providing access between the interior of the housing and an exterior of the housing, and the housing constructed to withstand contact by a piece of moving equipment; a mounting plate extending at least approximately perpendicularly downward with respect to the bottom surface to secure the housing to a peripheral portion of a concrete pathway having a surface portion to be illuminated, wherein in use the bottom surface of the housing is carried by the concrete pathway on a portion that is at least approximately parallel to the surface portion to be illuminated and the mounting plate is proximally adjacent and parallel to the peripheral portion of the concrete pathway, the peripheral portion which extends at least approximately perpendicularly with respect to the surface portion to be illuminated; and a light source received in the interior of the housing, the light source having a principal axis of emission that is directed outwardly through the window of the housing at a downwardly oriented angle with respect to the bottom surface such that, when in use with the luminaire mounted to the surface portion to be illuminated, the principal axis of emission of the light source is directed at the surface portion to be illuminated of the concrete pathway.
