LED packaged structure and applications of LED as light source

摘要

LED packaged structures and applications thereof are disclosed, characterized in that: an active layer in the LED or the LED packaged structure is formed on a first semiconductor conductive layer with multi-quantum wells; and a second semiconductor conductive layer is formed on the active layer; wherein a plurality of particles formed by at least one hetero-material are scattered between the first semiconductor conductive layer and the active layer in order to form an uneven multi-quantum well.
