In particular, the cartridge can be configured for rotation about a longitudinal axis thereof so as to be insertable into a chamber of the power unit in a plurality of different orientations. Further, the aerosol delivery device can include processing circuitry that can be configured for detection of the cartridge orientation and execution of a control function assigned to the respective orientation.

A light-emitting diode and a manufacturing method therefor are disclosed. The light-emitting diode comprises: a first conductive semiconductor layer; at least two light-emitting units arranged by being spaced from each other on the first conductive semiconductor layer, respectively including an active layer and a second conductive semiconductor layer, and including one or more contact holes through which the first conductive semiconductor layer is partially exposed; an additional contact area located between the light-emitting units; a second electrode making ohmic contact with the second conductive semiconductor layer; a lower insulation layer; and a first electrode making ohmic contact with the first conductive semiconductor layer through the contact holes of each of the light-emitting units and the additional contact area.

An integrated back light unit can include a light guide plate having a non-uniform distribution of extraction features. The non-uniform distribution of the extraction features can be provided by an extraction-feature-free region in proximity to a light emitting device, and/or by a variable density of the extraction features that changes with distance from the light emitting device. Additionally or alternatively, the light guide unit can include a heterogeneous reflectivity surface that has a different reflectivity at proximity to the light emitting device assembly than at a distal portion of the light guide unit. The different reflectivity may be provided by a specular reflective material, diffusive reflective material, or a light absorbing material. The non-uniform distribution of extraction features and/or the heterogeneous reflectivity surface can be employed to enhance brightness uniformity of the reflective light and/or to control the temperature distribution within the light guide unit.
