Indeed. I went to talk recently where they were saying that some offices now just use network connections for the whole system (including power) as it means they can centralise the driver system in the basement which simplifies everything.
- ghostly_s 10y agoCan you clarify? I don't see how a PoE network would allow you to centralize the driver hardware for LEDs, per spec I understand the power provided by PoE is straight DC with some sort of current negotiation process, and I don't think you could do PWM for LED drive across any great distance.
- apk17 10y agoI don't understand the general use of PWM anyway - you want to use switching regulators anyway, and it is actually slightly easier to do (almost) constant current than PWM. And PWM lighting is annoying in a lot of ways.
