Abstract

Dieser Stab löst das Problem der effizienten Lichteinkopplung in eine Suspension mit Mikroalgen () von obenThis rod solves the problem of the efficient coupling of light into a suspension with microalgae () from above

Description

Über dem Dach eines Hauses oder einer Industriehalle wird diffuses (1) und direktes Licht (2) So eingesammelt (3), dass es weitgehend parallel durch ein Rohr (4) geleitet wird, das von innen mit einer hoch reflektierenden (> 99%) Folie versehen ist. An die Dachdurchführung schließt sich ein Trichter (5) an, in den am engeren Ende ein Pyramidenstumpf (6) eingesetzt wird. Dieser undotierte Pyramidenstumpf ist bündig, ohne Grenzfläche an einen Lichtstab (7) angeschweisst. Dieser ist derart dotiert, dass Licht radial (8) abgestrahlt wird, derart dass ein Lichtleiterstab (9) entsteht, der optische Verluste von ca. 3 dB/m aufweist, sodaß nach 1 m Stablänge noch 50% des Lichtes aus der Stirnfläche (10) austritt.Above the roof of a house or an industrial building, diffuse ( 1 ) and direct light ( 2 ) So collected ( 3 ) that it is largely parallel through a pipe ( 4 ), which is provided on the inside with a highly reflective (> 99%) film. The roof duct is followed by a funnel ( 5 ), in the narrower end a truncated pyramid ( 6 ) is used. This undoped truncated pyramid is flush, without an interface to a light rod ( 7 ) welded on. This is doped such that light is radially ( 8th ) is radiated so that a light guide rod ( 9 ), which has optical losses of about 3 dB / m, so that after 1 m rod length still 50% of the light from the end face ( 10 ) exit.

Der Lichtleiterstab kann sowohl passiv mit Tageslicht, gemäß , als auch mit LED-Beleuchtung (11) gemäß betrieben werden. Dabei werden LED's im gewünschten Wellenlängenbereich (11) samt Kühlung auf der Oberseite des Pyramidenstumpfes montiert.The fiber optic rod can be both passive with daylight, according to , as well as with LED lighting ( 11 ) according to operate. In this case, LEDs are in the desired wavelength range ( 11 ) with cooling mounted on the top of the truncated pyramid.

Dieser Stab löst das Problem der effizienten Lichteinkopplung in eine Suspension mit Mikroalgen ( ) von obenThis rod solves the problem of efficient light coupling in a suspension with microalgae ( ) from above Die Einkopplung kann passiv mit Tageslicht, kombiniert mit einem Trichter erfolgen ( )The coupling can be done passively with daylight combined with a funnel ( ) Die Konzentration des Lichtes auf den Stabquerschnitt erfolgt über Totalreflexion an der Aussenfläche des KonusThe concentration of light on the rod cross-section via total reflection on the outer surface of the cone Die Dotierung des Stabes kann angepasst werden an die Höhe des Photobioreaktors Im Bespiel der betrug diese 3 dB/mThe doping of the rod can be adapted to the height of the photobioreactor this was 3 dB / m Zusätzlich kann der Kopplungskonus mit einem Fluoreszensfarbstoff, z. B. Rhodamin dotiert werden, wobei grünes Licht in rote Strahlung umgewandelt wird, welche zur Photosynthese geeignet ist.In addition, the coupling cone with a fluorescent dye, eg. As rhodamine be doped, green light is converted into red radiation, which is suitable for photosynthesis. Der Lichtstab zeichnet sich dadurch aus, dass hochkonzentriertes Licht mit geringer Intensität radial abgestrahlt wird (vorteilhaft für Algenzucht)The light bar is characterized by the fact that highly concentrated light with low intensity is radiated radially (beneficial for algae breeding) Der Aussenmantel des Stabes ist so behandelt, dass kein Biofilm anhaftetThe outer coat of the rod is treated so that no biofilm adheres Insbesondere eignet sich der Stab für die Anwendung bei Photobiorektoren, bei denen die Lichtverteilung durch eine Blasensäule erfolgt ( ). Dort wird das Licht direkt über die Austrittsfläche in die Blasensäule überführt!In particular, the rod is suitable for use in photobiorctors in which the light is distributed through a bubble column ( ). There, the light is transferred directly via the exit surface into the bubble column! Der Lichtstab durchdringt den anfallenden Schaumteppich effizientThe light rod penetrates the resulting foam carpet efficiently
