Abstract: An end cap for a solid-state lighting device is described that provides an electrical connection(s) between an external power source and at least one solid-state emitter disposed in a hollow member of the lighting device. An outer wall extends a first distance and an inner wall extends a second distance from an inward-facing side of the end cap base. A gap between the inner wall and the outer wall accommodates the insertion of the hollow member. A contactor electrically coupled to a conductive member on an opposite side of the end cap extends into the gap. The contactor exerts a force on a flexible conductor and provides a power supply path to or power return path from the at least one solid-state emitter. Preferably, the lighting device includes an array of solid-state emitters disposed on a flexible substrate.

Abstract: There is described an edge assembly for attaching to flexible substrates. An example assembly may comprise at least a first edge component and a compression retainer component. The first edge component may include at least one conductor to mate with one or more conductors on a surface of a flexible substrate after the first edge component is affixed to an edge of the flexible substrate by the compression retainer component. The edge assembly may also comprise a second edge component, wherein the flexible substrate may be compressed between the first and second edge components and held in place by the compression retainer component. The first edge component may further comprise an extension, including the at least one conductor, that may be used to convey power from a power source to the flexible substrate. The extension is accessible from outside the flexible substrate via a port in the compression retainer component.

Abstract: There is herein described an LED lamp suitable for replacing conventional fluorescent lamps. The LED lamp has a tubular body and a flexible circuit board as compared to the rigid circuit boards used in other similar lamps. The flexible circuit board has a plurality of LEDs, electric circuitry for powering the LEDs, and a curvature that is maintained by a retention means. The curvature of the flexible circuit board substantially corresponds to the curvature of the tubular body which places the LEDs further away from the front surface of the lamp thereby allowing for improved diffusion and light distribution.

Abstract: Reflector-type lamps and housings with integrated heat distribution and EMI shielding are disclosed. A reflector-type lamp includes a lamp housing having a base portion, a reflector portion, and an integrated heat distribution structure. A light source may be located in a reflector housing region or cavity defined by the reflector portion and integrated electronics may be located in a base housing region or cavity defined by the base portion. In general, the heat distribution structure distributes heat from hot spots in the lamp to exterior locations along the base portion and/or reflector portion. The heat distribution structure may also provide electromagnetic interference (EMI) shielding when EMI is generated within the lamp, for example, in the integrated electronics.
