I was wanting to control a cheap ($7) rgb floodlight that comes with IR remote with an arduino. We'll say teensy but really probably a pro mini or something of similar quality to the light.
I have made a slight tweak to to the IRremote library to let me send the IR code directly to the floodlight without the need for a IR LED on my side or the IR receiver on the floodlights side.
The question I have is I'm connecting my 5vdc external wiring to this lamps 5vdc wiring coming out of its resin sealed black box.
What is an easy way to insure isolation between the floodlights data/gnd and the floodlights 240vac supply?
Or put another way, prevent the possibility of a failure in the floodlights black box can't liven up my external arduino and wiring.
If inside my floodlights black box is a voltage devider across the mains and rectified.
Thanks.
I'm an electrician, so I feel safe maintaining correct isolation when making connections inside floodlight.(I know some people worry when reading posts like this)
On a side note. What is done in normal certified equipment like a computer power supply to prevent a component failure livening up the elv supplies? E.g. If an isolation transformer fuses together
Not the lamp in question, but took this the other week. A 50W floodlight installed in our factory.
