I don't think that this LED signals (Dialight) are used in our german traffic lights.
I will try in the future to get a close picture of the lens of our LED traffic lights.

So.. Are the dialight LED modules designed to look incandescent?
So this is how it works, there are a couple LED's inside the module, then they put a circlular franel lens to magnify the LED's to make them look BIGGER, and then the outside diamond lens with the color is what scatters the light and then makes it look incandescent...

Right?

Yes they are. Most companies have moved to the incandescent look design. Dialights diamond lens was the 2nd design. First was a crosshatched design, and the latest is a screened (looks like little squares) pattern.

Dialight was the pioneer to this design. Leotek and other smaller brands copied the 2nd design. GE's GT1 copied the lens design of the current Dialight.

Ah I see.

Do you have a pic of what the crosshatch looks like? I am curious of what those were.

Used to have one. I sold it and a Dialight incandescent look version of a green arrow a few years back. Found a pic of a yellow one, best I could do. The red and green are 2nd design, the yellow is a first: Old Dialight

Oh I see, looks like a normal incandescent. Why did traffic signal companies want an incandescent look?

the cities wanted to maintain the uniform appearance of the old incandescent fixtures. They're easier on the eyes then a pixelated look.

We still have alot of signals in the city with older LED Modules that have the Individual Diodes visable....when they start burning out they look horribly tacky.

One intersection has TERRIBLE LED Modules in the signals with lots of the LED's burned out and some non-pixelated ones mixed in. Hampton (285) And University. Old signal, span wires, M-400 r3's and bad LED modules in the signals.

Anyway, Yeah I see, I prefer the incandescent looking ones better. Anyway..

How do the new dialight design and the GT1 LED modules work? Like how they make it incandescenty.

you basically answered your own question earlier. 12 or so High Flux LEDs mount in the back of the housing. Shine through a fresnel lens to magnify the light and then through a tightly mated colored lens, with a pattern to bend like much like the incandescents bulbs.

Oh, so they are made the same as the older dialights. With just a new screen like front lens instead of a diamond pattern or crosshatch. Why exactly did they want to change to a screen like pattern?

supposably better light transmission. I thought the diamond pattern was the best. The screen lens doesnt transmit the light as good. GE's GT1 version with the screen pattern does transmit light better.

I like the Diamond pattern the best too. It looks the most incandescent.

I notice some of the diamond patterns looked different, One had more brighter light in the middle and the outside of the center was dimmer, others were more scattered and dimmer a bit in the middle.

I don't think that the LED signals in Israel are Dialights.
Hashmal Habarak company imports them, and they are made by S.C.A.E corporation.
The Dialights looks significantly different then our S.C.A.E LED signals.
