Design Challenge:

Create a solid-state LED light source capable of producing a 24" x 8" elliptical pattern with an output of at least 350 Lumens from a 12” distance without multiple shadow effects or optical distortion 5 inches from the illumination surface.

DDP's Solution:

10 1-Watt high-lumen emitters with collimating optics and a holographic diffuser - 6,0000-Kelvin color temperature, less than 2% radiated energy above 700nm, 420 Lumens (42 Lumens per watt).

Design Challenge:

Design a dual-brightness LED light source that can create usable work light in high and low ambient light conditions that conforms to NVIS standards for use with night vision goggles.

DDP's Solution:

A custom bi-color array of 5,5000 -Kelvin and 525nm SMT emitters, embedded in an extruded aluminum frame to illuminate a grid of meters and switches. The circuit was designed so that one or both colors could be energized as needed.
