Abstract: The nitride semiconductor light emitting device includes a first conductivity-type nitride semiconductor layer, a first superlattice layer disposed on the first conductivity-type nitride semiconductor layer, a pit forming layer disposed on the first superlattice layer and having a plurality of V-shaped pits, a second superlattice layer, an active layer, and a second conductivity-type nitride semiconductor layer disposed on the active layer and filling the V-shaped pits. The second superlattice layer is disposed on the pit forming layer and has windings that have the same shape as a shape of windings generated by the V-shaped pits. The active layer is disposed on the second superlattice layer and has windings that have the same shape as the shape of the windings generated by the V-shaped pits.

Abstract: A clothes dryer with a filter unit and a filter cover having a coupling structure corresponding to each other. The clothes dryer includes a body, a drum installed inside the body, a drying unit configured to dry air passed through the drum, a filter unit disposed on the drying unit and detachably installed on the body, a filter cover fixed by provided with one side thereof being installed on the body and the other side thereof being coupled to the filter unit. When the filter unit is not assembled, a user may notice the filter unit not being assembled due to the filter unit and the filter cover, both of which are provided with a coupling structure corresponding to each other.
