Abstract
High voltage array light emitting devices and fixtures are disclosed. In one embodiment a light emitting device can include a submount, a light emission area disposed over the submount and a retention material adapted to be dispensed about the light emission area. The light emitting device can be operable at high voltages which are greater than approximately 40 volts (V). In one aspect, the retention material can be least partially disposed within the light emission area such that the retention material physically separates a first section of the light emission area from a second section of the light emission area.
