    • A lens for distribution of light from a light emitter having an emitter axis and defining an emitter plane. The lens including an emitter-adjacent base end forming an opening to an inner cavity surrounding the emitter. An inner-cavity surface includes an axis-adjacent first inner region configured for refracting emitter light rays away from the axis, a second inner region spaced from the first inner region and configured for refracting emitter light rays toward the axis, and a middle inner region joining and substantially cross-sectionally asymptotical to the first and second inner regions. The middle inner region is positioned with respect to the emitter to refract light away from the axis by progressively lesser amounts at positions progressively closer to the second inner region. The lens further has an outer surface including output regions each configured for refracting the light from a corresponding one of the inner regions such that at the outer surface light from each inner region is refracted substantially without overlapping light from the other inner regions.
    • 用于从具有发射器轴并且限定发射极平面的发光体分配光的透镜。 透镜包括发射器相邻的基端,形成围绕发射器的内腔的开口。 内腔表面包括被构造用于折射远离轴线的发射体光的轴相邻的第一内部区域,与第一内部区域间隔开并且被配置为朝向轴线折射发射体光线的第二内部区域,以及中间内部区域 并且基本上横截面地渐近地与第一和第二内部区域成一直线。 中间的内部区域相对于发射器定位,以便在逐渐靠近第二内部区域的位置逐渐减小光线从轴线折射。 透镜还具有包括输出区域的外表面,每个输出区域被配置为折射来自相应的一个内部区域的光,使得在外表面处来自每个内部区域的光基本上折射而不与其它内部区域重叠。

    • An LED apparatus for illumination toward a preferential side in a downward and outward direction including a shield member in the form of a layer positioned over LED packages and secondary lens members. The shield member has a shield portion and a substantially planar non-shield portion thereabout. In preferred embodiments, the shield portion extends over a part of the lens portion of the secondary lens member. A cover preferably secures the shield member with respect to the secondary lens member, the primary lens and the LED package, the shield member preferably being sandwiched between the cover and the flange of the secondary lens member.
    • 一种朝向向外和向外的优选侧照明的LED装置,包括位于LED封装和次透镜构件上的层的形式的屏蔽构件。 屏蔽构件在其周围具有屏蔽部分和基本平坦的非屏蔽部分。 在优选实施例中,屏蔽部分在次透镜部件的透镜部分的一部分上延伸。 盖子优选地将屏蔽构件相对于次级透镜构件,主透镜和LED封装固定,屏蔽构件优选地夹在第二透镜构件的盖和凸缘之间。
