    摘要： A method for indirectly illuminating an interior space is disclosed wherein a laterally extended overhead distribution of light is produced from a source of indirect lighting, such as a fluorescent indirect luminaire, by directing a portion of the source light upward to produce a luminance pattern on the ceiling surface directly overhead and then refracting substantially all of another portion of the source light laterally of the indirect luminaire so as to spread the refracted portion away from the directly overhead luminance pattern. Illustrated is a luminaire having trough-shaped lensed for achieving the method of the invention wherein the lateral portions of the lens act to refract the light laterally as above described, and the top lens portion is formed to diverge the light incidence thereon directly overhead in a substantially uniform luminance pattern which is extended by the light refracted through the lateral lens portions.

    摘要： An indirect lighting system having a generally visible light transmissive element, such as a prismatic lens element or a diffuser strip, which modifies the direction of the light incident thereon from a secondary light source. The lighting system has a primary light source and structural means for positioning the primary light source proximate a reflective surface which reflects light back toward the light transmissive element and which thereby acts as a secondary source of light for illuminating this element. A light foil means is disposed between the primary light source and light transmissive element for substantially blocking direct transmission of light to the latter from the former. The light foil means, by keeping primary source light from directly striking the light transmissive element, forces the observable brightness in this element to be induced substantially entirely by the reflected light from the secondary source.

    摘要： A linear light passing media, typically a linear prismatic lens or a linear diffuser strip, is provided with linear areas of coloration to give a striped effect to the media. Color or neutral stripes are provided to areas of the media that are observable by persons standing in the vicinity of the lighting fixture; they act to give the media a psychological pleasing appearance, or on linear prismatic lenses, to mask out bright strips on the prismatic surfaces or at the base of the lens.

    摘要： A luminaire has a brightness reduction cover element below and in proximity to the active light source of the luminaire to simulate a larger light source having a lower surface brightness which is exposed through the luminaire's down light opening. For example, where the luminaire has a high output T5 lamp, the brightness reduction cover element can be in the form of a substantially semi-cylindrical opal diffuser cover strip sized to simulate a T8 or T12 lamp. An opal diffuser cover strip having two side-by-side arcuate portions joined at opaque interior edges can be positioned under two side-by-side T5 lamps to simulate side-by-side T8 or T12 lamps. For a direct-indirect luminaires the brightness characteristics of the exposed light source is governed by the lower brightness mock light source, while the uplight distribution of the luminaire is produced from the higher intensity light emitted from the top surface portions of the T5 lamp (or other active light source) for maximum control over the indirect lighting component of the luminaire.

    摘要： A luminaire includes a source of light in an opaque housing which extends beneath the source and upwardly about the sides of the source to hide the source from direct view from a horizontal line of sight even with the source. A lens is mounted to the housing above the source and extending around to join with the upper edge of the housing. The lens includes an upper light-dispersing portion which diverges one portion and only displaces another portion of the light from the source to provide an even distribution of luminance to a ceiling above the source. The lens also includes a lateral light-bending portion which receives light from the source and fans it out laterally over the side of the housing to continue the uniform illumination pattern of the ceiling and to illuminate vertical surfaces in the vicinity of the luminaire. A reflector beneath the source directs light onto the lateral light-bending portion of the lens to at least partly compensate for the fact that the light passing through the lateral portion of the lens normally travels farther to the surface it is illuminating and also strikes any horizontal surface at an increased angle of incidence. The lens and housing cooperate to enclose the source of light to prevent dust from entering, and the lateral portion of the lens provides a visible source of light to a person in the room being illuminated.
