  1. Modern technologies in the artificial illumination of aquariums with respect to exigent aquatic organisms Rudskiy Ivan Nefedova Ekaterina Laboratory of Scientific Projects Saint-Petersburg Institute of Limnology RAS Saint-Petersburg Zoological Institute RAS Saint-Petersburg 2016

  2. Index Laboratory of Scientific Projects LED technology : natural and artificial light for aquariums Light demands of Human and Phototrophic organisms LED light intensity LED light spectrum LED light aesthetics

  3. LED technology : natural and artificial light for aquariums Laboratory of Scientific Projects Advances and drawbacks of Metal Halide lamps (MH) Efficiency : luminosity up to 150 lm/w Light spectrum : full sunlight Electricity consumption Heating Light pulsation : 30%, 50 Hz Short lifetime : 6000—10000 h

  4. LED technology : natural and artificial light for aquariums Laboratory of Scientific Projects Metal Halide lamps (MH) vs LED (Light Emitting Diodes) Luminosity up to 150 lm/w Full sunlight Electricity consumption Heating Light pulsation : 30%, 50 Hz Short lifetime : 6000—10000 h Luminosity up to 200 lm/w Full sunlight in compositions Low electricity consumption No high heating Light pulsation : less 1%, n MHz Long lifetime : 50000—100000 h

  5. Light demands of Human and Phototrophic organisms Laboratory of Scientific Projects Light demands of Human : Curve of colour sensitivity and Colour perception Light demands of Phototrophs : Spectrum of light absorption and Curve of the photosynthesis efficiency

  6. LED light intensity Laboratory of Scientific Projects Lenses 5-60° Illuminance vs surface

  7. LED light spectrum : 380 – 520 nm Laboratory of Scientific Projects Deep sea imitation Water color compensation Intensification of the coral fluorescence

  8. LED light spectrum : 520 – 620 nm Laboratory of Scientific Projects Shallow water imitation Naturality of colours Combination of diffuse color and emissive color due to the fluorescence More balanced spectrum Less balanced spectrum

  9. LED light spectrum : 620 – 760 nm Laboratory of Scientific Projects Shallow water and direct sunlight imitation Naturality of colours Plant growth control : suppression of Symbiodinium sp. In coral tissues Absorption spectrum of plant phytochromes
