NOVELTY - The assembly has a light guiding plate (14) mounted on one side of a solar cell (12). A frame (10) releasably holds the solar cell and the light guiding plate. An LED array (16) is releasably mounted with the frame and adjacent to the light guiding plate such that the light generated by the LED array passes through a side surface of the light guiding plate and illuminates an area in front of the light guiding plate or the light guiding plate. The solar cell is a single crystal solar cell, poly-crystalline solar cell, thin film solar cell or plastic solar cell.    USE - Light assembly for a roof light and a lighting block on a roof. Can also be used as an outdoor decoration lamp, a courtyard lamp, a garden lamp, an advertisement lamp, a streetlamp, a warning sign, an indication sign for road application, a roof light for a parking lot or bus station, a roof light at a parking lot entrance or a light on a glass roof.    ADVANTAGE - The frame is in contact with both the solar cell and the LED array, and the solar cell and the LED array are separate, thus enabling to dissipate heat generated from the solar cell and the LED array during the operation of the light assembly through the frame efficiently. The LED array and the solar cell are separately and releasably attached to the frame, thus enabling the LED array or the solar cell to be replaced without damaging the light assembly. The light receiving area that collects the sunlight and the light emitting area through which light is emitted through the light guiding plate are not same, thus avoiding partial loss of the sunlight due to the reflection and/or scattering of the light from the light guiding plate.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of manufacturing a light assembly.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional side view of the light assembly with a light guiding plate mounted on a farthest side of a solar cell.
