The bypass air is then expelled through an outlet of a support strut positioned in fluid communication with the tail-cone cavity. The fairing inlet and the strut outlet are both positioned in a plane substantially perpendicular to a longitudinal plane of the engine. In this manner, circulation of the bypass air through the fairing, the tail-cone cavity, and the strut may be achieved. The bypass air directed through the fairing further enables cooling of service lines accommodated in the fairing. A lobe mixer is further used to direct the fairing and shield the latter from core exhaust. | 03-20-2014 |

20090296416 | REAR-LOADED LIGHT EMITTING DIODE MODULE FOR AUTOMOTIVE REAR COMBINATION LAMPS - A rear-loading LED module for a rear combination lamp is disclosed. One or more LEDs are mounted on a printed circuit board that mechanically holds them at the focus of a faceted, parabolic reflector. Light from the LEDs diverges transversely and horizontally, and is collimated by the reflector, and the reflected collimated light is directed in a generally longitudinal direction out of the rear combination lamp, toward the viewer. The LED module itself is generally longitudinally oriented, and is insertable longitudinally into the interior of the reflector from a hole at the vertex of the reflector. The printed circuit board, an optional thermal pad adjacent to the printed circuit board, and a thermally conductive layer adjacent to the optional thermal pad are all generally planar layers, are all generally parallel to each other, and may optionally all have the same footprint. Together, the printed circuit board, the thermal pad and the thermally conductive layer may all form a generally planar ledge. | 12-03-2009 |
20090296417 | REAR-LOADED LIGHT EMITTING DIODE MODULE FOR AUTOMOTIVE REAR COMBINATION LAMPS - A rear-loading LED module for a rear combination lamp is disclosed. One or more LEDs are mounted on a printed circuit board that electrically powers and mechanically holds them outside a faceted, parabolic reflector. Light emitted from the LEDs enters a light propagation region, formed between the reflective adjacent faces of two nested cylinders. The cylinders extend from the LEDs, outside the reflector, longitudinally through a hole at the vertex of the reflector, to the focus of the reflector. In some applications, the light propagation region may act as a beam homogenizer, so that light exiting the light propagation region may have roughly uniform intensity. Light from the light propagation region strikes an outwardly-flared reflector that directs it largely transversely onto the parabolic reflector. The parabolic reflector collimates the light and directs it longitudinally, through a transparent cover and out of the lamp. The parabolic reflector may have facets that angularly divert portions of the reflected light to form a desired two-dimensional angular distribution for the exiting beam. | 12-03-2009 |
20090296418 | SIDE-LOADED LIGHT EMITTING DIODE MODULE FOR AUTOMOTIVE REAR COMBINATION LAMPS - A side-loading LED module for a rear combination lamp is disclosed. One or more LEDs are mounted on a distal side of a printed circuit board, which also includes the circuitry that drives the one or more LEDs. The circuit board and a thermal pad are screwed/riveted to a heat sink, then the heat sink is mounted to a lateral face of a housing. The LEDs emit diverging light laterally inside the housing. One face of the housing is a faceted parabolic reflector, which receives the diverging light from the LEDs and reflects a collimated beam longitudinally to the front of the housing, where it passes through a clear cover and exits the lamp. The facets on the parabolic reflector angularly deviate portions of the reflected beam, so that the reflected light is collimated, and is angularly broader than a single collimated beam. | 12-03-2009 |
20100182788 | LED LAMP ASSEMBLY - A robust LED lamp may be assembly by forming a heat sinking sandwich with two metal heat sinks positioned around the circuit board and pinned together a heat conductive element.

The robust assembly is rapidly assembled, thermally effective in draining or spreading heat from the circuit board and is readily adaptable to a variety of applications lighting. The heat sink may be decorated, colored or otherwise esthetically enhanced for consumer appreciation. | 07-22-2010 |
