    • An apparatus, system and method for lighting an area, for example, an outdoors pedestrian area or building facade or an auto traffic area, or an indoor large area, which provides indicator/guide light, reference light for structures, and task lighting for a target area. The method uses first lighting sources that are directly viewable by observers and which can be historical, architectural, or aesthetically selected sources, but which produce a relatively low level of light or luminance insufficient to effectively light the area but sufficient to act as an indicator or guide, as well as to provide reference illumination on buildings or structures. Second lighting sources are configured to produce directional light to light the area but hide the light sources from most conventional observer viewing angles and may be enclosed within the general outlines of the globe or transmissive surface area of the fixture. Additionally, the fixture may appear to the average observer that the two sources are one historic or architectural source. Use of low-level directly viewable sources allows lower levels of light from the second sources to effectively light the area. This produces benefits regarding light pollution, such as reducing sky glow, glare, and spill light, as well as reducing energy usage.
    • 照明区域的装置,系统和方法,例如室外步行区域或建筑物立面或自动交通区域,或室内大区域,其提供指示器/引导灯,用于结构的参考光和用于 目标区域。 该方法使用可由观察者直接观看的第一光源,其可以是历史,建筑或美学选择的源,但是产生相对低的光或亮度水平不足以有效地照亮该区域,但足以充当指示器或 指导,以及为建筑物或建筑物提供参考照明。 第二光源被配置为产生定向光以照亮该区域,但是将光源从大多数常规观察者视角中隐藏并且可以封闭在灯具的通用轮廓或透射表面区域内。 另外,固定装置可能对平均观察者来说,两个来源是一个历史或建筑来源。 使用低级直接可见光源允许来自第二光源的较低水平的光线有效地照亮该区域。 这可以减轻光污染的好处,例如减少天空发光,眩光和溢出光,以及减少能源消耗。
