Solution Approach 1:

The light source assembly is integrated directly onto the lampshade, creating a unified heat dissipation system. The lampshade serves as both a structural component and a heat dissipation pathway, directly conducting heat from the light source to the external environment, thereby increasing heat dissipation capacity and extending service life

Inventive Principle:

Solution Approach 2:

The heat generated by the light source, which is a harmful factor that limits power and service life, is converted into a beneficial heat transfer pathway. By integrating the light source assembly with the lampshade, the heat is efficiently conducted through the lampshade to the external environment, transforming the harmful heat accumulation into an effective heat dissipation mechanism
