Power over Ethernet to operate LED lightings easily

LED lightings especially LED tubes, downlights and strip lights already saves at least 50% of electrical consumption. However, installation costs has always been a sore factor obstructing LED lighting implementation.

At the current technology and digital era, most of commercial, retail and homes are already being wired up with CAT 5 data cable enabling wireless network. New buildings will probably have fiber installed for faster internet speed and connectivity. How about we use this to power all our indoor LED lightings? Essentially, this is the concept of DC power distribution; where electrical power is passed along ethernet cable.

Riding on this infrastructure not only reduces the labour costs, it also reduces the conventional materials (e.g. Electrical wires, conduit, setting aside space or boxes) required for a building, work spaces and living quarters. Through which, greater benefits can be harnessed (e.g. the ability to dim the lights, connectivity and controls using smart devices, gathering of data on usage patterns.)

Additional benefits;
1. Electrical power can be transmitted over greater distances.
2. Do not require use of high voltage wires (230v AC).
3. Reduce need on typical electrical infrastructure for fluorescent/conventional lighting.
4. Does not affect data transmission with correct installation.
5. Minimise labour and materials.
6. Ability to link up lightings to smart devices through internet networks allowing instant control. (good for high security premises or sensitive high valued storage vault or data centres)

As we can see, LED lightings is moving beyond just physical returns on investment. There is this greater user experience that can be associated. All these are made possible as LED lightings are semi-conductor to be begin with.

We'll be exploring in this area further to bring greater benefit for all our led lightings users. Do look out for future write up to be published on that.
