Hangzhou 14 year old boy was LED Street patent

The eleven day, the 14 year old Ling is not so easy where the child. Just by virtue of a wind LED street to get the national utility model patents, he is busy in November to participate in the twenty-fifth Hangzhou Youth Science and technology innovation contest.

"I'm writing a paper for this invention. Ling Zifan pointed to the side of the nearly two meters high machine, green semi cylindrical surface, just 2-3m/s of the wind speed can be achieved rotating power, and then tie a piece of solar panels on top, just like a scenery complementary system. It is this wind LED street lamp, let him harvest a national utility model patent.

According to Ling Zifan's father, said Ling Rongting, since the child was patented, within a month, there have been dozens of research institutes, fairs, companies looking for them, hoping to cooperate with them.

Find inspiration from typhoon in Cangnan

Talk about creative inspiration, Ling Zifan said, all this from the summer of 2011, Cangnan typhoon. At that time, sitting in front of the television to see him, after the typhoon many lights, billboards damaged, and even hurt people. At this time, his mind can not help out a question: how to reduce the damage of these lights, billboards?

On the material level, these street lights, billboards have enough. However, Ling found that these street lights, billboards are flat, when the wind blows side, the damage will be much higher than the number of.

At that time, the school science class is learning the principle of air pressure". Under the same pressure, if the force area increases, the pressure will be reduced. So, how to increase the area under the premise of constant space?

Curved surface! Thought of here, Ling Zifan very excited, he immediately brought a few pieces of A4 paper, several small stick, a small electric fan, at home to start a test. It was just the second to him every Saturday at home, all the love nest in the room with the pieces of paper. Sometimes, tired to sleep, hand still drag two white paper.

He was clinging to the surface to increase the degree of firmness, but after a failure of a new discovery. "Once, because the installation is not fixed, the surface turned, the rotation will produce mechanical energy. Ling Zifan said, because the topic of new energy is very popular, he quickly thought of energy conversion.

Semi cylindrical surface

Power generation efficiency can be increased by more than 30%

At that time, wind street lamps in coastal areas is not uncommon. However, where the child found in the wind Ling, street lamp in the existing, most upright wing design, wind blade for blade shape. These wind power street lamps in the larger areas, often by the wind area is not large, the power generation efficiency is not high, and easy to damage.

In the process of changing the angle of the surface, Ling Zifan also realized that the gradual formation of semi cylindrical surface can effectively solve this problem.

"When a wind LED lamp fixed in one place, Shoufeng device can only receive a complete direction of the wind, blowing from the side of the case, the wind receiving efficiency will be reduced. "Ling Zifan said, when the surface is changed into semi cylindrical Shoufeng / device can receive 360 degrees to the wind, thus improving the efficiency of power generation device.

"In this way, the street lamp can achieve self-sufficiency to a greater extent, thus reducing the waste of resources due to the laying of various types of wires. Ling Zifan said, according to their own experiments, the device power generation efficiency can be improved by more than 30%.

When the wind speed is only 2-3m/s, the street lamp can realize self power generation. Ling Zifan said the device plus a piece of solar panels, just like a scenery complementary system.

At the end of September 2011, Ling Zifan will send the design draft to the national patent bureau. At the same time, he is still stuck in the fan blade angle, the problem will be faced after the commissioning, the two major changes. In August this year, he finally received a patent certificate.

A company intends to buy a patent

When the marine economy continues to be concerned about, Ling Zifan also began to consider the new wind energy LED street lamp to the ship. "The sea wind speed is relatively large, this device can give full play to its advantages, not only to ensure that no damage, but also to achieve greater efficiency of power generation. "

Currently, the 14 year old boy has received a number of research institutes, fairs, the company's invitation, hoping to buy the patent. "Of course, the parameters of the vertical axis of the device must be measured and determined before it is put into production. Ling Zifan said that his greatest desire is that the device can bring some help to the community, benefit.

Currently, he is working with second wind related patent applications, the application has been accepted. The possibility of a large audit, basic in more than 80%. Ling Zifan full of confidence.
