Abstract: 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.

Abstract: An automotive combined turn signal and tail/stop lamp (10) having co-axial transparent collimating inner and outer light guides (18, 30). Inner collimating light guide (18) receives light from a yellow LED (16), outer collimating light guide (30) receives light from red LEDs (14), the yellow and red LEDs located in thermal communication with a common heat sink (2). Mirror optics (40, 42) reflect light from respective light output prisms (28, 35) of the inner and outer light guides outward to nested reflectors on the automobile. Electrical conductors (48) between the light guides (18, 30) can feed power from a PC board (12) to supply additional light sources within an RCL housing, such as white back-up light.

Abstract: 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.

Abstract: A replacement vehicular lamp assembly (10) configured for insertion into a vehicle chassis-mounted lamp housing (110) originally containing an incandescent lamp (118) installed in an aperture (102) in a chassis-mounted reflector (116). Lamp assembly (10) has a housing (12) supporting LED(s) and displaceably mounted reflector segments (40) moveable between a closed configuration facilitating installation through the aperture (102) and an outwardly open configuration for function within the lamp housing (110) to form a first reflector (38). A biasing mechanism (25) biases the reflector segments (40) to the open configuration to deploy the first reflector (38) overlying the chassis-mounted reflector (116) so that light from the LED is received on the first reflector (38) defined by the reflector segments (40).
