Illumination assembly for underwater illumination

An illumination assembly (10) for providing illumination in an underwater medium which at least partially absorbs light, characterized by comprising

• a light sensing unit (300) having at least one fluid chamber (420) having a hollow body (500), pluralities of fluid intake openings (421) opened outside from said fluid chamber (420) and providing fluid input to the fluid chamber (420), at least one light source (330) positioned inside the fluid chamber (420) and which emits light in at least one first spectrum, at least one photo-diode (310) positioned inside the fluid chamber (420) in a manner facing said light source (330) and which generates signal related to the distribution in said first spectrum and optical intensity of the wavelengths of the light, which is emitted by the light source (330) and which passes through water;
• at least one LED array (150) which can emit light in the first spectrum;
• at least one LED driver (110) which sets the optical intensity of the light emitted by said LED array (150) and the distribution thereof in the first spectrum;
• a control unit (120) which determines the operational setting of said LED driver (110) and connected to said photo-diode (310) in a manner receiving said signal as input;
• said control unit (120) is configured in a manner applying the signal received as input to a function which gives output in proportion to the light intensity and in a manner changing the operational settings of the LED driver (110) in order for the LED array (150) to emit light in accordance with the output of said function;
• further comprising
• at least one flap (220) is provided which extends from its own body towards outside.
