Abstract:
1. A solar illumination device comprising: a pivotal electricity generation and storage assembly comprising a parallelepiped main body having a planar front end, a planar rear end spaced from and parallel to the planar front end, a planar top surface, a planar bottom surface spaced a height and parallel to the planar top surface, a planar first side surface, and a planar second side surface spaced a width from and parallel to the planar first side surface, with the planar top and bottom surfaces extending perpendicularly between the planar front and rear ends and between the planar first and second side surfaces; at least one solar cell panel mounted on at least one of the planar top and bottom surfaces; an internal circuit board and a rechargeable battery in the parallelepiped main body, wherein electricity generated by the at least one solar cell panel is supplied to the rechargeable battery for charging via the circuit board, wherein the circuit board controls on or off of the charging of the rechargeable battery; a pivotal illumination assembly comprising a parallelepiped housing having a front end, a planar rear end spaced from and parallel to the front end, a planar top surface, a planar bottom surface spaced the height and parallel to the planar top surface, a planar first side surface, and a planar second side surface spaced the width from and parallel to the planar first side surface, with the planar top and bottom surfaces extending perpendicularly between the front and rear ends and between the planar first and second side surfaces; a light source mounted on the front end of the parallelepiped housing; a switch mounted on the parallelepiped housing, with the switch adapted to manually press to either connect the rechargeable battery to the light source via the circuit board or disconnect the rechargeable battery from the light source via the circuit board; and two planar links each comprising a first pivot pivotably connected about a first axis to a predetermined position of one of first and second side surfaces of the illumination assembly and a second pivot pivotably connected about a second axis to a predetermined position of one of first and second side surfaces of the electricity generation and storage assembly, wherein each link has rectangular cross sections parallel to the first and second axes, with the link having a thickness parallel to the first and second axes which is less than the height, with each link abutting with one of the side surfaces of each of the parallelepiped main body and of the parallelepiped housing; wherein the front end of the illumination assembly is a recess; wherein the light source is an LED (light-emitting diode) assembly comprising a plurality of LEDs disposed in the recess; wherein the plurality of LEDs are arranged linearly and equidistantly; wherein the predetermined position of the illumination assembly is a midpoint thereof and the predetermined position of the electricity generation and storage assembly is adjacent the rear end thereof; wherein a first length is defined as a distance between each second pivot and the rear end of each side surface of the parallelepiped housing, wherein a second length is defined as a distance between each first pivot and the rear end of the parallelepiped main body, wherein two pivot points of each link are respectively mounted on the first pivot and the second pivot, wherein a distance between the first and second pivots of each link is greater than a total length of the first length plus the second length; wherein the electricity generation and storage assembly pivots clockwise or counterclockwise about the second pivots freely, and wherein the illumination assembly pivots clockwise or counterclockwise about the first pivots freely.
