A lighting assembly is provided with a housing defining a cavity that is aligned along a longitudinal axis. A light source is supported by the housing and aligned with the longitudinal axis. A lens is supported by the housing to collimate light from the light source. An image plate with a plurality of apertures formed through passes a portion of the collimated light as light segments. An exit lens includes a first series of optics arranged on a first plane spaced apart from the image plate at a first focal distance to focus the light segments at a first distance from the housing, and a second series of optics arranged on a second plane spaced apart from the image plate at a second focal distance to focus the light segments at a second distance from the housing. The second focal distance is greater than the first focal distance.

A heat sink includes an extruded component, a cast component, and an interface layer. The extruded component includes a first aluminum material and is configured to be coupled to a solid state light source. The cast component includes a second aluminum material overmolded onto a portion of the extruded component to form the interface layer. The interface layer is formed of at least one of the first and the second aluminum materials and abuts against and couples the extruded component to the cast component.

Lamp optic for use in LED-based lamp

Lamp optic for a vehicle lamp

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.
