Power company came by and got broken street light working again today. A new thing I see now, but never noticed in the past, is a top module that flashes an IR emitter. Motion sensor?
It appears to be at the top and incorporated into the dusk-to-dawn PEC (photoelectric cell), for what purpose, I have no idea, but I doubt that it's a motion sensor. None of the NEMA twist-lock PEC's we used atop the luminaires had them. That looks like a flat-top style that I'm not familiar with. After dealing with municipal traffic signals and street lighting for 31+ years from '73 to' 04 I retired in '04, over 20 years ago so very well could be something new...at least to me.
It may be so they can see from the ground with a hand-held viewer ( smartphone) before going up if the street light has power without causing customer curiosity and complaints from a visible spectrum LED..."why is that LED flashing?" so they made it IR.
Dude didn't even attempt to trim the encroaching vegetation that was all over that PEC. He'll be back when the wind whips the tree and the limb damages the PEC.
