Apparatus for converting light energy into electrical energy including photoelectric cells connected across a storage device providing a direct voltage input to a d.c. transformer, which converts its direct voltage input into a higher voltage alternating or intermittent output and comprising an oscillator or switching circuit having a photosensitive device connected in its timing circuit so that the frequency of oscillation or switching varies with the illumination level of the photoelectric cells. |
