OPTIMAL SOLAR CONCENTRATOR DEVICE AND SENSOR COMPRISING A PLURALITY OF SUCH CONCENTRATOR DEVICES

摘要

The invention relates to a solar radiation concentrator device comprising a device reflecting said radiation and focussing it at at least one focussing zone (25) acting as energy collector characterized in that the reflecting device exhibits at least two proximal portions (31) each extending from a focussing zone (25), and exhibiting a concave reflecting surface whose normals are tangent to the theoretical envelope surface of the focussing zone or zones (25), the concavities of the reflecting surfaces of the proximal portions (31) being oriented oppositely from the focussing zone or zones (25) so as to define a common aperture for receiving the solar radiation. It extends to a sensor comprising a plurality of concentrator devices according to the invention.
