Now here’s a creative design that is not only Green, but also cost-effective. Solar Traffic Light has been designed to include Discolor LED (Light Emitting Diode) technology, essentially hosting all the three colors of the lights within a single unit. Red, Amber and Green all together! The lights source power from the Solar Panel on top of the unit, which is elegantly designed as a hood. Quite Brilliant!

What were you going to do about the red/green colour blind population of the world who rely on positional information to know the status of the lights? This very old idea was abandoned over 30 years ago for exactly this reason.
Agreed, although I still like the idea very much (‘cuz it’s square 😉 ).
You could solve the colorblind issue by assigning shapes to colors (similar to pedestrian lights), like they have in Halifax.
It would also be neat to display the time left, by disabling certain LED’s to display the number.
even with different shapes for each light, it would take some time for colorblind people to get used to

Folks the problem for the colorblind/blind people is also covered in the design. Each light has a different shape and color:
Green = Rounded circle (O)
Yellow = Triangle (A)
Red = Cross (X)
This design is really good and has a Reddot award. Nice Job Yao&Co!
Jose.
Soooo, it is neither made for the sight impaired nor really practical, and gets an award?
I guess Reality isn’t a category at Reddot.
grasping at straws
Of course not. That's why it's called a concept. If you want reality, go find another site.

Hi,how much does it cost?
good idea, i'll like to know more about the circuitry and its mode of operation. i'll also like to know if it can be timed.

IMO a safety-critical system like this could never rely on having a string of unbroken sunny days to continue operating.
You are right ! But ' normal ' traffic lights don't work sometimes as well !

I agree with Mr. Almond. The color blind issue kills this idea.
Not necessarily. Look closely at the third picture. The green light is an open ring. The red is probably a solid circle, and the amber something else, perhaps an X. That makes it very obvious what is what.
It’s green but not good. They totally ignored color blind people. Research? Ops!
Lots of regular stop signs ignore the colorblind. After all, they are just circles stacked on top of each other. You are making a mountain out of an anthill.

Can’t see why this system wouldn’t work out well enough. You need:
1) Outside power source as a backup to solar charging.
2) Color and shape differences for stop, caution, and go
I work in the street furniture industrty in the UK and this looks like a nice product, however; the solar cells are too small to power the LEDS, would need to at least double the size.
OK, so Traffic lights are mostly used in urban area, what happens when the panel is in the shade at certain times of day? This can cause a reduction in efficiency of up to 90% so then you are back to using you grid source. When you add it all up this product would probably have a buy back period of over 20 years and more energy would be used to have it in place rather than leave the traffic lights alone.
Along with the colour issues others have identified I cannot see any commercial merit in the prouduct.
Does it realy mather seriusly if u can cut 30-50% of the used power a year then u already did alot for the inviroment, u will offcorse need external power at night
I still love this idea and should be considered by many countries tht can efford it
要是中国的马路上野可以装一个这样的红绿灯就好了
Where can i buy this product and hw much is it??
