TURNING DEVICE FOR SOLAR POWER MODULE Russian patent published in 2010 - IPC F24J2/54 

FIELD: lighting.

SUBSTANCE: turning device for solar power module refers to automatic tracking systems of light source and is intended for automatic orientation of battery plane after light source (the Sun) as per its maximum light intensity. Special light intensity sensor, signal processing device and electronic timer is introduced to turning device design; at that, light intensity sensor includes two photo diodes fixed on carrying plate installed parallel to solar battery plane, and reflector representing a plate with white matt surface, which is installed parallel to battery rotation axis and perpendicular to its plane so that it cannot come into the shade of battery at any Sun position. At specified time intervals, electronic timer supplies to signal processing device the command to measure light intensity values of each of two photo diodes; at that, during the first measurement, after power supply has been switched off, or in case difference sign of these values has changed in comparison to the previous measurement, signal processing device switches the timer off and supplies power supply from solar battery output to electric motor in order to turn solar battery in the direction of more illuminated photo diode until difference sign of light intensity values of photo diodes changes; after that, signal processing device switches off electric motor and switches on the timer.

EFFECT: invention allows simplifying tracking system design and reducing costs of electric power consumed with turning device.
