A lighting network includes a lighting network base station and one or more contactless lighting network components. The lighting network base station includes: a radio frequency (RF) amplifier which supplies an RF power signal to a lighting network line pair; and a first power line communication coupler which couples the lighting network line pair to a first power line communication device. The contactless lighting network component extracts electrical power from the RF power signal on the lighting network line pair, and couples the lighting network line pair to a second power line communication device. The first and second power line communication devices communicate network data via the lighting network line pair. The contactless lighting network component may include a lighting fixture (e.g., including one or more LED light sources), a sensor, and/or a lighting network interface adaptor.

The present application is directed to heat sinks for light emitting devices. In particular, the heat sinks can provide effective heat dissipation in a variety of different orientations and positions. In one exemplary heat sink, different groups () of essentially parallel fins () can be separated and disposed at particular angles to form fluid channels (and) that enable fluid flow in different directions and orientations.
