Abstract
Abstract A solar lighting device for garden or driveway according to this invention transforms solar energy into electric energy using a solar energy absorbing plate and stores the electric energy into an electric battery. A light sensor turns on the lighting circuit during dark hours. The solar lighting device of this invention comprises a solar energy absorbing plate, a shell, an electric battery, a focusing reflector, a lens, and a set of connecting links. The shell has two openings, one opening is inclined with respect to the shell and adapted for the insertion of the solar energy absorbing plate. The other opening is for inserting the lens. The shell holds an electric battery, a board, and a focusing reflector. Also the solar energy absorbing plate engages with the inclined opening of the shell using lugs formed on the rim of the plate, and the frame of the lens is pivotally mounted on the other opening of the shell.
