PHOTOVOLTAIC ENERGY SOURCE COMPRISING A BATTERY, PREVENT PREMATURE AGING OF THE BATTERY, LIGHTING HEAD THEREFOR

摘要

The invention relates to a power source formed by a box supporting on its upper face a photovoltaic panel and a battery housed in said box and separated from said photovoltaic panel by a blade of air flowing between vents formed on at least two opposed surfaces of said box. According to the invention, the source further comprises a heat shield (20) disposed between said photovoltaic panel, and said battery, with a spacing between said heat shield (20) and said photovoltaic panel (2) to ensure the circulation of said blade air. The invention also relates to a lighting head comprising such a source. The invention finds application in the field of photovoltaic energy sources.
