    • The present invention comprises a light fixture including a housing, a light source, means to secure a light source to the housing, a lens and a reflector. The reflector and lens are positioned so as to direct light from the light source onto an unlit side of the housing.The light fixture is normally suspended from the ceiling or attached to a wall. A greater portion of the light from the light source is reflected off the ceiling or wall, whereas a smaller portion of the light from the light source is reflected off the reflector and onto the housing. After the smaller portion is reflected off the housing, the smaller portion and the larger portion are traveling in generally the same direction, thereby reducing the contrast between the housing and the ceiling or wall.The present fixture housing is very shallow, preferably less than about 3" deep. It includes one or more side rails, with each side rail being utilized to reflect the light from the light source onto the housing with a first reflector and to alter other diffuse lighting characteristics with a lens, perforated metal, or a second reflector.
    • 本发明包括一种灯具,其包括壳体,光源,用于将光源固定到壳体的装置,透镜和反射器。 反射器和透镜被定位成将来自光源的光引导到壳体的未照射侧。 灯具通常悬挂在天花板上或附着在墙壁上。 来自光源的较大部分的光从天花板或壁反射,而来自光源的较小部分的光从反射器反射到壳体上。 在较小部分从壳体反射之后,较小部分和较大部分沿大致相同的方向行进,从而减小了壳体与天花板或墙壁之间的对比度。 本装置外壳非常浅,优选小于3“深。 它包括一个或多个侧轨,每个侧轨用于将来自光源的光用第一反射器反射到壳体上,并且用透镜,穿孔金属或第二反射器改变其它漫射照明特性。
