Abstract: A light-emitting arrangement including an optical member and a light-transmissive shield member secured with respect to the optical member at least partially defines a light-fixture exterior and having a back side facing a circuit board and receiving a gasket which encircles the circuit board to provide a water seal thereabout. The gasket has a pair of spaced apart outwardly-extending lateral fingers engaging lateral sides of a recess formed by the optical-member back side, and at least one inner finger extending into the recess offset from the recessed lateral sides. A peripheral wall extends from the optical-member back side outwardly around the gasket and engaging an emitter-supporting to minimize water ingress toward the gasket. An opaque shield is disposed along at least a portion of a perimeter of the optical member and configured and dimensioned to minimize or block distribution of light in at least one direction opposite the direction of the primary illumination.

Abstract: The LED lamp has a relatively long, narrow configuration similar to that of CFL bulbs. Because the lamp operates at relatively high power and produces significant lumens, a significant amount of heat is generated by the LED assembly. The interior envelope of the lamp, defined in traditional CFL bulbs by the fluorescent tubes, is used to house a heat sink having a shape and dimensions to fit inside of the form factor of the CFL tubes. The heat sink substantially fills the interior space of the optically transmissive enclosure in order to provide maximum surface area for dissipating heat from the LEDs. A plurality of fins may extend from the heat sink to the exterior of the lamp to dissipate heat from the LEDs to the ambient environment.
Abstract translation: LED灯具有与CFL灯泡类似的相对长的窄型配置。 因为灯以相对高的功率运行并产生明显的流明，所以LED组件产生大量的热量。 用荧光灯管定义在传统CFL灯泡中的灯的内部封套用于容纳具有形状和尺寸以适合CFL管的外形尺寸的散热器。 散热器基本上填充光学透射外壳的内部空间，以便提供用于散发来自LED的热量的最大表面积。 多个翅片可以从散热器延伸到灯的外部，以将热量从LED散发到周围环境。

Abstract: A driver module is configured to generate the drive signals necessary to drive an LED or an array of LEDs of one or more LED luminaires. The driver module may, but need not, be located remotely from the LED luminaires. Since the driver module provides the drive signals, the LED luminaires do not need to have their own driver electronics, and as such, can be rendered in a more aesthetically pleasing and cost effective manner. As an example, the driver module may be located within a junction box or escutcheon plate associated with a light fixture and the LED luminaires can be mounted in the existing sockets of the light fixture. The internal wiring of the light fixture may be used to carry the drive signals provided by the driver module to the LED luminaires via the sockets of the light fixture.

Abstract translation: 驱动器模块被配置为产生驱动一个或多个LED灯具的LED或LED阵列所需的驱动信号。 驱动器模块可以但不必要远离LED灯具。 由于驱动器模块提供驱动信号，所以LED灯具不需要具有自己的驱动器电子元件，并且因此可以以更美观和成本有效的方式呈现。 作为示例，驱动器模块可以位于与灯具相关联的接线盒或孔罩板内，并且LED灯具可以安装在灯具的现有插座中。 灯具的内部布线可以用于通过灯具的插座将驱动器模块提供的驱动信号传送到LED灯具。
