- What do you think about this? see, and tell us now.
- The Lens is.
- Too bad these don't work in cities that have snow. These things are hot enough to melt snow, so the lights get covered and that leads to accident fail lol
- I want a purple one for my room!
- Well my understanding of LED and incandecent lamps is that LED lights and turns off more quickly than incandecent units.
- the way to go
- "Since they don't develop any heat, blowing snow can stick and block the light." They're far below 100% efficient, so they do generate heat. Just a lot less than a 5% efficient light bulb(even less when you consider the colour filter that removes most of that 5%)
- I live in St. Louis, MO and have seen snow build up on the LEDs before. That's the one good thing I liked about the old style lamps, the heat would melt the snow off. Also, one time, for instance, I was at an intersection where they were going from yellow to red, the yellow went off and the red signals took like, 5 seconds to come on; when the other direction already had their green light. This never happened before they replaced the lenses. With the old style, you never had to worry about that.
- one way or the other,traffic moves better when they aint working,sure this is the case in cities other than Edinburgh
- Why do the colors only come in Red Yellow and Green? D:
- @agiwch The light system of using three lights can't be changed because of color blind people. They look at the lights left to right or up and down to determine if it's red, yellow or green. If it was a one bulb light system, they could not tell what to do at a traffic light, but don't stop being creative.
- Well, I saw on the news a few days ago that cities that are replacing traffic lights with LEDs are now having trouble with the lights getting covered up in snowstorms, since they don't give off heat. All this "green" crap is pissing me off. If I get into an accident due to a snow-covered LED traffic light, I'm sueing the shit out of the city.
- is the green light actually so blue or is it just the camera
- guess what?.. i have LED tail-lights on my car.. WOW!!
- OLED Tv's are better :D, but lifespan fails!
- Not really dimmable since they draw so little current. The ITE spec calls out that if one sections goes out no less then 25% of the light can be lost. JPP...
- @LEDtronics Er, try how would a color blind person... know what "color" the light is? You will *always* have 3 lights due to this... the colors are nice, but a color blind person must go by location.
- what about arrows, wouldnt it be hard for it to have an arrow
- I want my traffic lights with Blue instead of green do you guys make those?
- So far, I'm not impressed with LED signals. I don't know which signal manufacturers my city buys from, but most of the green LED signals around town have from 10% to 60% missing segments. Also, the amber signals are about half as bright as the others. Even the walk signals have burned-out sections, and all are under five years old.
- It's great except it doesn't melt the snow in winter so they get all covered up.
- OMG people, the 3 light system are for people that can not see color. Top stop, middle slow down, bottom go. I def remember this from drivers ED does no one else.
- most people think that led are those small long lightbulb types that are used for electronics but these days they use chips that have current flowing past them that light up, thats how they have those 1 inch led tvs
- i think the reason why they do this is that they help with people who are either partially color blind or even totally color blind.
- They have tested LED traffic lights in my area in London. Particularly on a pelican crossing outside Sainsbury's supermarket in Camden Town. But the problem was, when you pulled up at the stop line, you couldn't see what colour light was showing because of the angle you were at in the car! So they took them down and put back the latest pre-LED style.
- Thanks, Our LED traffic lights are made with very high quality LEDs, as they say failure is not an option. JPP...
- LED revolution XXI
- Pretty sure the color doesn't matter in the power drain since all LEDs use 20mA of power each correct?
- I have another saving idea......if the leds switch separatly .....and we can manage the three colors .....why using the three leds ....!!!!!!!!!!? My great Idea is using one led.....and changing colors only.....intresting
- This would depend on the Lens over the LED. Some could have a lens that point down because the Green is so bright at night that some people complain about it. We use a special lens that spreads the light left to right so it is easier to see in all directions. JPP...
- I wish more places in the US would start to use these.
- @LEDtronics No the reason you don't use a single light is for the color blind who rely on the location of the light and not the color.
- I've noticed some of these with the green light aimed down so you can't see it from very far away, but the red and yellow are still focused high. I know I'm approaching those lights more cautiously... Always thinking, "Is it broken, or is it green? or could it be red and I'm just not seeing it?" XD
- @agiwch My wife and father in law are color blind. He sits at green lights and gets mad at reds when the guy in front wont go. I like where your heads at, its a good idea! On Paper.
- @LEDtronics but they dont perduce enough heat to take out the risk of icing over look it up its a problem
