Abstract: An LED light engine includes a housing, one or more LEDs mounted on a printed circuit board and a retention feature engaged with the housing. The retention feature includes one or more of a torsion spring and a friction clip and is configured to engage an inside wall of a recessed lighting can, thereby retaining the LED light engine within the can. The LED light engine may also include a reflector and a lens retained within the housing, with the housing, reflector and lens forming a sealed chamber for protecting the LED components from external environmental conditions. Methods for retrofitting an existing recessed downlight fixture with an LED light engine include removing the existing light engine from the recessed lighting can and inserting an LED light engine into the can.

Abstract translation: LED光引擎包括壳体，安装在印刷电路板上的一个或多个LED和与壳体接合的保持特征。 保持特征包括扭转弹簧和摩擦夹中的一个或多个，并且构造成接合凹入的照明罐的内壁，从而将LED光引擎保持在罐内。 LED光引擎还可以包括反射器和保持在壳体内的透镜，壳体，反射器和透镜形成密封室，用于保护LED组件免受外部环境条件的影响。 用LED灯引擎改造现有的嵌入式筒灯具的方法包括将现有的光引擎从凹进的照明罐中移除，并将LED光引擎插入罐中。

Abstract: A single board light engine includes an AC to AC step driver that selectively powers multiple LED segments by controlling tap points between the LED segments as the input voltage goes from zero crossover to maximum voltage and returns to zero crossover. The step driver may power a first LED segment, a second LED segment, both the first and second LED segments, or none of the LED segments depending upon the input voltage level. The LEDs within an LED segment may share a characteristic that differs from a characteristic shared by LEDs in another segment, which allows the LED fixture to provide a variety of lighting effects.

Abstract translation: 单板光引擎包括AC到AC步进驱动器，当输入电压从零交叉到最大电压并且返回零交叉时，通过控制LED段之间的分接点来选择性地为多个LED段供电。 步进驱动器可以为第一LED段，第二LED段，第一和第二LED段供电，或者根据输入电压电平为LED段供电。 LED段内的LED可以共享与另一段中的LED共享的特性不同的特性，这允许LED灯具提供各种照明效果。
