A packaged optical device includes a substrate having a surface region with light emitting diode devices fabricated on a semipolar or nonpolar GaN substrate. The coupling is formed unitarily from a resin material and has first and second coupling halves that are joined unitarily along a living hinged. The plurality of nozzles are positioned under the grate. One of the side faces defines a channel communicating with the cavity for receiving therein a latch arm of the complementary connector. Instead of replacing a device with a larger capacity device, storage capacity can be expanded. A self biased power supply eliminates the need for an external power supply by deriving a high voltage bias from the stator AC signal voltages which have been rectified and run from a high voltage tap andor through a voltage multiplier which has a voltage limiting means.
