The document summarizes the design of a flashlight collimating system. It discusses properties of LED emitters and the objective to collimate light into a bright hotspot to increase throw. A collimating system typically uses a reflector, lens, or optics combination. Reflectors can vary the depth to diameter ratio to control hotspot size and spill light. Lenses can form a sharp image of the emitter but require addressing chromatic aberration. Optics provide more flexibility and allow total internal reflection for high efficiency. The document proposes improving reflective coatings and developing optimized reflector-like optics.
