Young and young have won patents for LED lamps for 14-year-old boys in Hangzhou

National Day was not so easy for Ling Zifan, 14 years old. He just got a national utility model patent with a wind energy LED street light, and he is busy attending the 25th Hangzhou Youth Science and Technology Innovation Competition in November.

“Now is writing a paper for this invention.” Ling Zifan pointed to a machine that was nearly two meters high by the side, a green semi-cylindrical leaf surface, and the wind power of 2-3 m/s could be used to generate electricity by turning and then cooperating with the top. A solar panel, like a wind and solar systems. It is this wind-powered LED street light that has earned him a national utility model patent.

According to Ling Rongfan's father Ling Rongting, since the children received the patent, within a short period of one month, dozens of research institutes, expos, and companies have already found them and hope to cooperate with them.

Finding Inspiration from Cangnan Typhoon

Talking about creative inspiration, Ling Zifan said that all this must start with the typhoon in Cangnan in the summer of 2011. At that time, he sat in front of the TV and saw that after the typhoon, many street lights and billboards were damaged and even bruised. At this time, his mind can not help but flash a question: how can we reduce the damage of these street lights, billboards?

Talking about the firmness of materials, these street lights and billboards are enough. However, Ling Zifan discovered that these street lights and billboards are all flat. When the wind blows on the side, the damage will be much higher.

At that time, the "Principles of Pressure" was being studied in the school science class. Under the same pressure, if the force area increases, the pressure can be reduced. So, how can we increase the area of ​​force under the premise of constant space?

Surface! Ling Zifan was very excited when he thought of this. He immediately brought in a few A4 papers, several small sticks, and a small electric fan. He started experimenting at home. At that time, he had just graduated from junior high school. He returned home every Saturday and liked to dunk in the room. Sometimes she fell asleep tired and had two blank sheets on her hands.

Originally obsessed with adding solidity through the surface, he found new discoveries after a failure. “On one occasion, because the installation was not fixed, the surface turned and the mechanical energy was generated by turning.” Ling Zifan said that since the topic of new energy was very hot at that time, he soon thought of energy conversion.

Using semi-cylindrical leaves to set the power generation efficiency can be increased by more than 30%

At that time, wind-powered street lamps were not uncommon in coastal areas. However, Ling Zifan found that among the existing wind energy street lamps, most of them were designed as vertical fins, and the wind-bearing blades were generally in the shape of a propeller blade. These wind-powered street lamps are often affected by winds in areas with large wind power, and their power generation efficiency is not high and they are easily damaged.

In the process of constantly changing the surface angle, Ling Zifan also realized that the semi-cylindrical leaves gradually formed can effectively solve this problem.

“When a wind LED street light is fixed at a place, the wind receiving device can only receive the wind blowing in one direction completely. If blowing from the side, the efficiency of wind receiving will be reduced a lot.” Ling Zifan said, when the wind When the surface is changed to a semi-cylindrical leaf surface, the device can receive the wind 360°, thereby improving the power generation efficiency of the device.

“In this way, the street lights can be more self-sufficient, thereby reducing the waste of resources caused by laying all kinds of wires.” Ling Zifan said that according to his own tests, the power generated by the device can be increased by more than 30% .

When the wind speed is only 2-3m/s, the streetlight can generate electricity by itself. Ling Zifan said that the installation of a solar panel, like a wind and solar systems.

At the end of September 2011, Ling Zifan sent the design draft to the National Patent Office. At the same time, he was still clinging to the perspective of the fan blade and the problems he would face when it was put into production. Two major changes were made. In August this year he finally received a patent certificate.

A company intends to buy a patent

When the marine economy continued to receive attention, Ling Zifan also began to consider the new wind LED street light to the ship. "The speed of wind on the sea is relatively large. This device can give full play to its advantages. It can ensure that it will not be damaged, but it can also generate electricity with greater efficiency."

At present, the 14-year-old boy has received invitations from many research institutes, expos, and companies, hoping to buy this patent. "Of course, before the official production, the parameters of the vertical axis of the device must be measured and determined." Ling Zifan said that his greatest desire is that this device can bring some help for the community, and have some benefits.

At present, he is working on the second application related to wind power and the application has been accepted. "The possibility of passing the review is very large, basically more than 80%." Ling Zifan full of confidence.
