Strange LED Streetlamps
(1/3) > >>
Cyberdragon:
I saw some strange yet beautiful LED streetlamp bulbs in Baltimore the other day. Some sort of art deco/futuristic styled ones. I don't have photos but I can describe them. Their construction is as follows:

-shiny metal base with a pattern in it (I assume a heatsink), the pattern is similar to gas/oil burner bases
-3-4 cylindrical light pipe diffusers (depending on bulb wattage I again assume) with concave tops like giant strawhat LEDs jutting up out of the base
-color temp: unknown (seen during the day when off)

Has anyone seen anything like this or know what model or brand they would be?
Cyberdragon:
From what I have found, they were probably installed recently during their LED lighting project.

The fixtures don't look like anything they've shown. They appear to be retrofit bulbs. I doubt I'll be able to see them on Google maps either as it would have to be a very recent streetveiw.
Cyberdragon:
After finding a bunch of lights still not retrofitted (digging around on streetview) where I remember them to be, I found some that had been already (photos must have been taken during installation, they were all like this when I was there).

Here's one of the specimins...identify.

Cyberdragon:
I explored around in the recent...or maybe not, images. I don't even know if these are LED anymore, I think they might be sodium, or at least a mix. The crystal things are just diffusers, I found one stuck lit in daytime and they are lit from the top. Also, you can see some weird junk going on up top on some that does not look LED.

So far found on Portland St, Washington Blvd, and Emory St.


Fraser:
Looks like LED light pipes illuminating a top mounted light reflector. Commonly used to create a downward light spread and reduce light pollution. The light pipes may glow in darkness like a ‘candle’ or gas mantel but they will not emit significant uncontrolled light off their sides so the light distribution remains controlled by the reflector above them. The reflectors shape and angle distaste’s the reflected light coverage characteristics.

Simple physics and optics  :-+
