Optical Design

Following are a few examples of LSI’s optical design, research and development projects:

  • International Space Station – Exterior Lighting Systems; designed the lamps and exterior luminaires currently aboard the ISS
  • Mag-Lite® – Variable beam optical systems with moving lamp for flashlight
  • NASA Space Shuttle – Cabin Lights, Floodlights and Annunciators; all fluorescent lensing throughout the spacecraft, four personal floodlights used by the commander and pilot, and lenses for the panel displays to collect and redistribute light from miniature lamps for specific luminance and uniformity
  • Task Lighting – Furniture mounted fixtures with a side throw of illumination to provide glare free work surfaces. (Patented)
  • Department of Defense – F16 Aircraft; design and prototyping of taxiing and landing lights to government specifications
  • Automotive Headlights – Design of a series of automotive lenses to meet and exceed SAE specifications, using computer-automation
  • Roadway Lighting Reflectors – Series of reflectors for various light distributions using horizontal metal halide and sodium sources, providing high efficiency and sharp cut-off
  • Dental Lighting System – Optical design of a new form of dental examination light with cold mirror
  • Department of Defense, U.S. Naval Sea Systems Command – Marine Navigation Lights; the development of a range of shipboard lighting systems to provide color recognition and intensity patterns for collision avoidance at sea
  • Floodlights – Many floodlight designs for various NEMA classifications and light source types
  • Surgical Lighting Optics – Design of a widely-used system for a variable beam lighting system used in surgical operations
  • Gas Station Canopy Lighting – Design of a gas station canopy lighting system to effectively illuminate gas pumps while minimizing glare and light trespass
  • Reflectors for uniform ceiling lighting using HID lamps in building interiors. (Patented)
  • Sun-tracking Reflectors – Design of a 480 mirror heliostat system for sunlight tracking to provide interior daylighting. (Bank of Hong Kong and Shanghai)
  • Department of Defense – Underwater Reflectors; development of a range of complex optical systems used with metal halide, quartz and Xenon flash sources for underwater television surveillance by submarines. The optics are free-flooded with sea water causing unusual refraction problems
  • 8224 Refractive Grid Lens – A widely used product for glare reduction in fluorescent and HID interior lighting systems. (Patented)
  • Triumph I Lens – A 2′ x 2′ lens for HID sources which provides wide spacing and square distribution. Used worldwide; an overseas standard for gasoline station lighting. (Patented)
  • 3E Lens – Lens for providing extremely wide spacing of fluorescent luminaires and very high efficiency. (Patented)
  • Department of Energy – Lenses for Use with Daylighting Systems; development of lensing techniques to reduce the apparent angular motion of the sun, applicable to sunlighting systems using light pipes, light shelves and special fenestration
  • Paracube II Louvers – The design of parabolic metallized plastic louvers for elimination of direct glare (Patented)
  • Department of Transportation, Federal Highway Administration – LED traffic signals; investigations into methods of improving the optical and electrical efficiency of signal lights. These were some of the first LED traffic signals ever designed.
  • Department of Defense, U.S. Army, Fort Belvoir – Battlefield Decoys; research and development techniques to measure and specify realistic battlefield decoys; related to the optical characteristics of the materials employed.
  • Optical Systems with Interference Coatings – Multiple optical systems using thin film coatings for ultra-high reflectivity on aluminum, and glass transmission without efficiency losses. (Patented)
