Proposed LED/wired IoT standard can reduce energy use

While switching to LED lighting certainly helps reduce power consumption, we can do more. Each conventional mains powered LED bulb has its own AC/DC power supply, which is needed for bulbs to be compatible with AC wiring and lighting fixtures with sockets designed 100 years ago. Having individual power supplies adds cost and decreases efficiency and limits energy savings. A different system, one that distributes DC, could be more efficient.

Here is an interesting  two article series that proposes a new wiring system especially for LED lighting.

The new wiring standard will be for interconnecting smart LED light bulbs, wall light switches (on/off/dimmer), occupancy sensors, thermostatic temperature sensors, fans, duct dampers, thermal blankets that unroll over windows, solar PV arrays, and other IoT devices.

The proposed IoT base standard doesn’t define power wires. Power could be fixed 24 VDC, fixed 48 VDC, fixed 110 VAC, or fixed 220 VAC. In proposed system, ┬▒data wires connect multiple devices in parallel, devices communicate bidirectionally.
