A connector release tool () includes a shaft () having a proximal end () defining a handle () and an operative distal end () defining a shroud portion (). The shroud portion () includes sidewalls () extending away from the distal end () and terminating at a datum surface () and a channel () defined therebetween. The shroud portion () further includes a plurality of contact pins () extending away from the distal end () and into the channel () of the shroud portion (), each contact pin () adapted to engage an associated push-button connector of a terminal block () and allow removal of one or more wires () coupled to the terminal block ().

Connector release tool

A replacement lamp for an airport runway sign. Light is produced by a linear array of white-light LEDs. A cylindrical lens is mounted longitudinally adjacent to the LEDs, and collects a central portion of the light emitted from the LEDs. A pair of inclined surfaces extend from the lateral edges of the LEDs to respective lateral edges of the cylindrical lens. The inclined surfaces have a rough surface texture and reflect light diffusely. The inclined surfaces collect a peripheral portion of the light emitted from the LEDs, and direct the reflected light toward the cylindrical lens. The LEDs, cylindrical lens and inclined surfaces are all mechanically supported by a heat sink. The replacement lamp is placed into a runway sign near its top or bottom edge, and illuminates both viewing surfaces of the runway sign simultaneously without a diffuser.

Replaceable single LED lamp for runway sign

A two-sided airfield runway sign with direct illumination by a single LED lamp. Light is produced by a linear array of white-light LEDs. A cylindrical lens is mounted longitudinally adjacent to the LEDs, and collects a central portion of the light emitted from the LEDs. A pair of inclined surfaces extend from the lateral edges of the LEDs to respective lateral edges of the cylindrical lens. The inclined surfaces have a rough surface texture and reflect light diffusely. The inclined surfaces collect a peripheral portion of the light emitted from the LEDs, and direct the reflected light toward the cylindrical lens. The LEDs, cylindrical lens and inclined surfaces are all mechanically supported by a heat sink. The replacement lamp is placed into a runway sign near its top or bottom edge, and illuminates both viewing surfaces of the runway sign simultaneously without a diffuser.

Runway sign having a replaceable single LED lamp

A method of retrofitting an existing airfield runway sign with a single LED lamp. Light is produced by a linear array of white-light LEDs. A cylindrical lens is mounted longitudinally adjacent to the LEDs, and collects a central portion of the light emitted from the LEDs. A pair of inclined surfaces extend from the lateral edges of the LEDs to respective lateral edges of the cylindrical lens. The inclined surfaces have a rough surface texture and reflect light diffusely. The inclined surfaces collect a peripheral portion of the light emitted from the LEDs, and direct the reflected light toward the cylindrical lens.

A replacement lamp for a cinema poster display case. Light from a linear array of white-light LEDs reflects off a concave reflector to an illumination plane at or near a front face of the display case. The concave reflector intersects with surface normals from the LED emission faces along an intersection line. The concave reflector has proximal and distal portion on opposite sides of the intersection line. The illumination plane is disposed on an opposite side of the LEDs from the intersection line. The illumination plane has a proximal portion near the LEDs and a distal portion away from the LEDs. Light reflected from the LEDs off the proximal portion of the concave reflector is directed to the distal portion of the illumination plane. Light reflected from the LEDs off the distal portion of the concave reflector is directed to the proximal portion of the illumination plane.

A direct view LED lamp () comprising: a heat sink body () having a longitudinal axis () and a wall () having an exterior () and an interior (). A cavity () is formed in the interior () and is defined by a circumferential side wall () and a back wall (). A circuit board () is positioned in the cavity () adjacent the back wall (). At least one LED () is mounted on the circuit board () facing in an axial direction parallel to the longitudinal axis () and away from the circuit board (). An optical light guide () is positioned adjacent the at least one LED (). A housing () spans the cavity () and has a coupling face () to mate with the heat sink body ().

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 assembly is positioned by pressing it into a base providing electrical connections. 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.

LED lamp assembly

An LED lamp assembly with a substantial heat sink may be inexpensively constructed using sections of extruded metal as the heat sink. The extruded heat sink sections are trapped in latched sandwich structure assuring good thermal contact between the LED light sources and the extruded heat sink and a metal optic. The inexpensive structure may be rapidly assembled.
