Abstract
A luminaire for mounting on a vertical surface is provided, the luminaire including a housing having an aperture, a lamp disposed within the aperture and configured to emit light through the aperture to the vertical surface and to an associated worksurface, and a lamp distribution modifier disposed within the aperture proximate to the lamp, where the lamp distribution modifier is configured to intercept light rays emitted by the lamp in a direction toward an upper portion of the vertical surface.
Claims20
A luminaire for mounting on a vertical surface, the luminaire comprising:
- a housing having an aperture;
- a lamp disposed within the aperture and configured to emit light through the aperture to the vertical surface and to an associated worksurface;
- and
- a lamp distribution modifier disposed within the aperture proximate to the lamp;
- wherein the lamp distribution modifier is configured to intercept first light rays emitted by the lamp in a direction toward an upper portion of the vertical surface.
A lamp distribution modifier for being disposed proximate to a lamp within an interior of a downlight luminaire, comprising:
- an elongated body configured to extend along at least a part of a length of the lamp;
- a light passage feature disposed on the body configured to allow first light rays incident on a vertical surface to pass through the lamp distribution modifier;
- and
- a light intercepting feature disposed on the body and configured to intercept second light rays incident on the vertical surface;
- wherein the body is disposed so as not to be directly visible to a viewer of the luminaire.
A method of modifying light incident on a vertical surface emitted by a lamp of a luminaire mounted proximate to the vertical surface, the method comprising:
- disposing a lamp distribution modifier at an interior of the luminaire proximate to the lamp so as not to be directly viewable by a viewer of the luminaire;
- intercepting first light rays at the lamp distribution modifier incident on an upper portion of the vertical surface proximate to the luminaire;
- and
- allowing passage of second light rays through the lamp distribution modifier incident on the upper portion of the vertical surface and incident on a lower portion of the vertical surface disposed distal from the luminaire.
