Light-emitting diode (LED) arrays, and more particularly high power LED arrays and related devices are disclosed. Exemplary lighting devices with arrangements of LED chips and/or lumiphoric materials are capable of dynamically providing different color points and/or light outputs. Devices include individually controllable LED chips arranged on a common submount that may include integrated control circuitry for controlling operation of the LED chips. LED chips may be arranged to form sub-arrays of like-colored LED chips and corresponding electrical connections may include one or more shared electrical contacts. Certain aspects relate to arrangements where electrical connections are provided on opposite faces of submounts from the LED chips such that an increased density of LED chips may be arranged along primary emission faces. Applications for such high-power LED arrays and related devices include various color-changing lighting fixtures with high light output that may benefit from dynamic spectral tuning with improved precision.
