This 11th National Day is not so easy for 14-year-old Ling Zifan. He just got a national utility model patent with a wind energy Led Street Lamp, he is busy participating in the 25th Hangzhou Youth Science and Technology Innovation Competition in November.
"Now I am writing a paper for this invention." Ling Zifan pointed to a machine nearly two meters high next to him. The green semi-cylindrical blades only need 2-3m / s wind speed to rotate and generate electricity. A solar panel is like a wind-solar complementary system. It was this wind energy LED Street Lamp that made him harvest a national utility model patent.
According to Ling Rongting, Ling Zifan's father, since the child received the patent, in just one month, dozens of research institutes, fairs, and companies have approached them, hoping to cooperate with them.
Find creative inspiration from Cangnan Typhoon
Speaking of creative inspiration, Ling Zifan said that all this must start from the typhoon of Cangnan in the summer of 2011. At that time, sitting in front of the TV, he saw that many street lights and billboards were damaged after the typhoon, and even hurt people. At this time, a question came to his mind: How can we reduce the damage of these street lamps and billboards?
Talking about the ruggedness of the materials, these street lights and billboards are enough. However, Ling Zifan found that these street lights and billboards are flat, and when the wind blows from the side, the damage will be much higher.
At that time, the "Pneumatic Principle" was being studied in school science classes. Under the same pressure, if the force area increases, the pressure can decrease. So, how to increase the force-bearing area without changing the space?
Curved! Thinking of this, Ling Zifan was very excited. He immediately took a few sheets of A4 paper, a few sticks, a small electric fan, and started a test at home. At that time, he had just advanced to the second grade, and returned home every Saturday. Sometimes, I was tired and fell asleep, still pulling two pieces of white paper in my hand.
He was originally obsessed with increasing the firmness through the surface, but he made a new discovery after a failure. "Once, because the installation was not fixed, the curved surface turned, and the rotation would produce mechanical energy." Ling Zifan said, because the topic of new energy was very popular at that time, he quickly thought of energy conversion.
Traffic Lights are traffic lights that command traffic and are generally made up of red lights,green lights and yellow lights.The red light means no traffic,the green light is allowed to pass,and the yellow light is a warning.
Traffic lights are divided into:light motor vehicles, no-motor vehicles lights,pedestrian signal lights,direction indicator lamp(arrow lights),driveway lights,flashing warning lights,road and rail light plane crossing.
