Retreflectivity is everywhere. Truth. For example, on street lanes, which reflect when the car’s light hits. It is worn in clothing and even on the moon thanks to the Apollo mission.And increasingly, he is walking down the street under wheels.
Or, if it is not, it should!
This feature is absurdly simple and can make transit much safer, especially for cyclists.
Thinking about it, the Hub Bicycle Company, a 5-year-old Cambridge bicycle store in the United States, became the first to offer retro-reflective paint jobs on bicycles earlier this year. The company’s founder, Emily Thibodeau, joined with an industrial company called Halo Coatings which patented the only form of self-reflective powder, good mainly for use on highways and other infrastructures, in order to make people safer, since They become walking flags in this way.
How Much Is The Joke?
For something around $ 700, the Thibodeau team can submit their bike to an electrostatic spray of particles loaded with retroreflective paint until it is completely coated.
Then the carcass goes into an oven, where the paint is solidified and turns gray in the normal light, but it shines in a bright white strong in the dead of night when a light strikes it. Great, huh?
A Brief History Of Retroreflectors
The optical phenomenon known as retroreflection plays a huge role in the world, but few of us really understand the science at stake when cat eyes on the street reflect a frightening glow.
Here’s the simple version: when light is reflected on normal surfaces, like your car, for example, it spreads in all directions. When focusing on retroreflective materials, do not.They reflect the light back directly to your source without spreading it, which makes them bright when you are near that light source.
It All Started With The 7th Art
The story of how our infrastructure was lit is really interesting. Retroreflective materials were first developed by an unusual industry: the cinema.
In the 1930s, a company called Potters developed a kind of tiny glass sphere that could reflect light directly back to the source. These polka dots were “only a fraction of a millimeter in diameter, and were used for the first time in” silver screen “of the cinema giving a much brighter image.
Soon, Potters was looking for new applications for his screen magnifying beads, and they did so on traffic signs and bright roadblocks.
Before long, other companies were making their own retro-reflective bicycle coatings, and the American streets began to get much brighter. So, the genius idea had spread all over the world.
