A solid state microprocessor or digital signal processor (DSP) for dual mode illumination and dimming into modern aerospace searchlights. The system is a universal dimming platform with 'smart functions' that include and are not limited to multiple light intensity linearization curves, analog and/or digital input dimming interface, built-in tests and health monitoring, synchronized dual mode light output with canopy position, light driver redundancy, lamp life reporting, and controlled switching with improved EMI. With real-time monitoring of the system parameters it monitors the lights proper operation and failures which can be a concern for flight-critical lighting.

Dual mode searchlight dimming controller systems and methods

A lighthead for a dual-mode searchlight including a generally concave housing with an attached infrared (IR) light source assembly, an insulating barrier and air gap between the visible and IR portions of the assembly, and a reflector integral to the housing.

Integrated searchlight lighthead

A lighting device () includes one or more diode light sources (), which are configured to emit light into the peripheral edges of a light guide (). The light guide () includes a set of diffusing elements () for scattering the emitted light in a plurality of directions out of the front surface of the light guide (). The diffusing elements () are distributed on the light guide () so that the scattered light achieves a particular characteristic, e.g., improved uniformity.
