    • A parabolic troffer-style light fixture. The fixtures are sized to fit in, mount to, or suspend from a ceiling, such as being mounted in a conventional ceiling T-grid, for example. The fixture comprises a troffer housing that may be sized to fit in or rest on the T-grid, with the housing having a shape and size similar to those used for conventional fluorescent troffer lighting fixtures. The fixtures comprise a plurality of reflective louvers arranged in a grid that divides the fixture open end into a number of fixture regions with at least one functional louver providing a back side mount surface for light sources, for example, light emitting diodes. The functional louver mount surface faces a reflective back surface designed to redirect impinging light out of the fixture and into the lighted area.
    • 抛物线型灯具。 固定装置的尺寸适合于例如安装在常规天花板T形网格中的天花板上,安装到或悬挂。 该固定装置包括一个可以设计成适合或搁置在T形格栅上的尺寸的外壳,其外壳的形状和尺寸类似于常规荧光灯照明装置所用的形状和尺寸。 夹具包括布置成格栅的多个反光百叶窗,其将固定件开口端分成多个夹具区域,其中至少一个功能百叶窗为光源(例如发光二极管)提供后侧安装表面。 功能百叶窗安装表面面向反射后表面,设计用于将入射光引导出固定装置并进入点亮区域。
