Abstract

There is provided an illumination system (100) for cultivation of aquatic animals. The illumination system (100) comprises at least one light source (110) emitting light, at least one light driver (120) arranged to drive the at least one light source (110), at least one light sensor (130) providing illuminance data for at least one point of interest (50) in said illumination system (100), and a controller (140). The controller (140) is adapted to provide control signals to the at least one light driver (120) driving the at least one light source (110) to emit light of a desired illuminance at the at least one point of interest (50). An ambient light sensor may be applied to determine control signals also in accordance with ambient light data.

Claims13

Dependent claims

An illumination system for cultivation of aquatic animals in a body of water comprising:

a plurality of light sources, each light source comprising at least one light emitting diode arranged to emit light, said plurality of light sources being arranged to be immersed in a body of water,
at least one light driver arranged to drive said plurality of light sources,
at least one light sensor arranged to provide illuminance data for at least one point of interest located in said body of water,
at least one ambient light sensor to provide ambient light data from sensing ambient light above the surface of the body of water, and
a controller, wherein said controller is adapted to
receive a desired illuminance setpoint for said at least one point of interest;
receive said illuminance data for said at least one point of interest from said at least one light sensor;
model light conditions within the body of water using the illuminance data at said point of interest and said ambient light data to account for a contribution of the ambient light at different depths;
determine control signals for said plurality of light sources based on said model and the received desired illuminance setpoint;
and
provide said determined control signals to said at least one light driver, thereby driving said plurality of light sources to achieve light of a desired illuminance at said at least one point of interest;
wherein said plurality of light sources are adapted to be individually controllable with respect to at least one of a light flux, a peak brightness and a spectrum in order to produce said light of said desired illuminance at said at least one point of interest.

A method for controlling light in an illumination system for cultivation of aquatic animals, said illumination system comprising a plurality of light sources, each light source comprising at least one light emitting diode arranged to emit light, said plurality of light sources being arranged to be immersed in a body of water, at least one light driver arranged to drive said plurality of light sources, at least one light sensor arranged to provide illuminance data for at least one point of interest being located in said body of water, at least one ambient light sensor to provide ambient light data from sensing ambient light above the surface of the body of water and a controller, said method comprising the steps of:

receiving a desired illuminance setpoint for said at least one point of interest;
receiving said illuminance data for said at least one point of interest from said at least one light sensor;
receiving the ambient light data from the at least one ambient light sensor in a controller;
modeling light conditions using the illuminance data at said point of interest and said ambient light data to account for a contribution of the ambient light at different depths;
determining control signals for said plurality of light sources based on said model and the received desired illuminance setpoint;
providing said determined control signals to said at least one light driver, thereby driving said plurality of light sources to achieve light of a desired illuminance at said at least one point of interest;
wherein said determining comprises determining individual control signals for said plurality of light sources in order to produce said light of said desired illuminance at said at least one point of interest;
wherein said determining comprises determining individual control signals with respect to at least one of a light flux, a peak brightness and a spectrum for said plurality of light sources in order to produce said light of said desired illuminance at said at least one point of interest.
