Botryllus Beamer - a novel LED reflector
This reflector generates a strong parallel focused beam of light while bundling the ray of several LEDs with elliptically formed concave mirrors. The beams of LEDs or other non-directed light sources are assembled to one light beam of strong luminous intensity without the need of any lens systems.
The elliptic concave mirrors focus the light onto a main reflector and one aperture in the center of the beamer. The principle is outlined in Figure 1.
The construction overcomes the typical wide angle beam characteristic of light emitting diods and makes them useful as light sources for spot applications and long distance projections. Fully encapsulated constructions for more sophisticated applications (e.g. under water lighting) are possible.
- Automotive and industry reflectors
- Fiber coupling of light sources
- Long distance lighting of areas and spots
- Ship technology
- Diving and other under water technologies (ROV, AUV, hand lamps)
- Scientific applications
- Theater illuminations and so on.
The combination of white and colored LEDs (including UV and IR emitting LEDs) within one lamp as well as the optional use of additional lenses offers a multitude of other specific applications.

State of development
A prototype using the Botryllus beamer principle for the use in a scientific instrument has been developed with industry partners and is ready for use. The overall technology is ready for a wide range of applications.
