    • A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis and defining an emitter plane. The lens has an emitter-adjacent base end forming an emitter-receiving opening to an emitter-surrounding cavity defined by an inner surface which includes a front sector centered on the preferential side and a back sector centered on the non-preferential side radially opposite the preferential side. The front and back sectors differ in their respective configurations for refracting light from the emitter. The lens further includes an primary back surface positioned to receive light from at least a portion of the inner-surface back sector and configured for total internal reflection (TIR) thereof. The inner-surface back sector and the primary back surface extend along substantially elliptical cross-sections in planes substantially parallel to the emitter plane. The emitter-adjacent base end forms a back opening to a back cavity substantially centered on the non-preferential side and partially bounded by the primary back surface.

    • An LED apparatus of the type including (a) a mounting board having an LED-supporting surface with an LED device thereon and (b) a lens member over the LED device establishing a light path therebetween. The inventive LED apparatus includes a lens-aligning member having front and back surfaces and defining an aperture receiving the LED device therethrough such that the LED device protrudes beyond the front surface. The lens member includes a lens portion and a flange thereabout, the flange being attached to the front surface of the lens-aligning member such that the lens portion substantially surrounds the protruding LED device. The lens-aligning member has a first mating feature which is positioned and arranged for mating engagement with a second mating feature of the mounting board, thereby accurately aligning the lens member over the LED device by accurately aligning the lens-alignment member with the mounting board. Other aspects of the invention is a method for LED-apparatus assembly and a method for manufacturing custom high-efficiency LED lensing for LED-array modules.
    • 一种LED装置,包括:(a)具有LED支撑面的安装板,其上具有LED装置,以及(b)在所述LED装置上方的透镜构件,在所述LED装置之间建立光路。 本发明的LED装置包括具有前表面和后表面的透镜对准元件,并且限定了通过其接收LED器件的孔,使得LED器件突出超过前表面。 透镜部件包括透镜部分和其周围的凸缘,凸缘附接到透镜对准部件的前表面,使得透镜部分基本上围绕突出的LED器件。 透镜对准构件具有第一配合特征,其被定位和布置成与安装板的第二配合特征配合接合,从而通过将透镜对准构件与安装板精确对准,从而将透镜构件精确对准在LED装置上 。 本发明的其他方面是一种用于LED装置组装的方法和用于制造用于LED阵列模块的定制高效LED透镜的方法。
