The utility model discloses a lampshade of a common lighting lamp, in particular to a power-saving light-integrating lampshade. The power-saving light-integrating lampshade is mainly characterized in that a light reflection mirror surface comprises a spherical zone (cap) shaped transparent glass hood, wherein, the inner face is connected (or not connected) with a reverse circular table (cone) shaped transparent glass hood, and the outer surface is coated with a light reflection layer. Moreover, the outer surface of the reflection layer is first added with a protective layer and then added with a protective hood. Thus, the light ray radiated by the lamp light source in the lamp shade to the not specified lighting areas is integrated at the specified lighting area after once or a plurality of times of reflections through the reflection mirror surface. Therefore, the purposes of brightness increasing at the specified lighting area and relatively electric light saving are reached.
