Xu Hongwen, who came out of the family courtyard of the Municipal Party Committee, was a little happy and a little disappointed, fortunately Yang Qin and her mother did not say anything against them being together, but she did not recognize Xu Hongwen, of course, Xu Hongwen can also understand Aunt Shen's good intentions as a mother, Xu Hongwen secretly encouraged himself after leaving the gate, and he must work hard to give Yang Qin a happy life!

After returning to the store, Xu Hongwen was busy until late at night again, and after three days of continuous busyness, Xu Hongwen assembled all the LED lights and LED light strips, and hundreds of samples piled up half of a room in the store.

In the evening, I rushed to Professor Zhang's office in the school's real room, Xu Hongwen, who was standing outside the door, knocked on the door of the office, and after hearing the sound of "come in" inside, Xu Hongwen pushed the door in, and saw the teacher sitting in the office and bowing his head to write something, Xu Hongwen, who entered the door, stepped forward and said, "Teacher, you are still busy!" ”

Professor Zhang Yuansong, who was writing a rewriting budget report, looked up and saw that it was Xu Hongwen, Zhang Yuansong knew that his student's academic attainments might not be lower than his, and in Haohan's sea of learning, it was like sailing against the current, and if he did not advance, he would retreat.

These days, he has not seen the figure of this beloved disciple in the real room, which makes him a little worried that this beloved disciple has gone astray, and the end of the year is the last issue of this academic year, and the doctoral and master's students who are about to graduate will immediately submit academic papers and participate in academic debates.

Although Zhang Yuansong agreed to Xu Hongwen's leave, he really didn't expect that this invitation would be rare to see two people for more than half a month, and Zhang Yuansong, who was a little unhappy, sat up straight when he saw Xu Hongwen entering, and asked: "Hongwen, what are you busy with these days!" ”

Xu Hongwen, who has been a man of two lives, walked into the teacher's office at this time, he has not come to the school for several days to take a serious class, he is still a little weak in the face of this academically rigorous old professor, and when he heard the teacher's words, Xu Hongwen replied: "Teacher, you also know that I borrowed the semiconductor room a few days ago, because I found that the light color of the diode is controllable, and the brightness can be enhanced by more than 20 times, which can reach the level of illumination!" ”

The light-emitting diode is generally simply used as an indicator light in the circuit, everyone knows that the brightness of the light-emitting diode is not high, Professor Zhang Yuansong was shocked after hearing Xu Hongwen's words, and he just heard Xu Hongwen say that he wanted to borrow a semiconductor for real room use.

He didn't care too much at the time, thinking that it was just an ordinary real thing, and now he knows that Xu Hongwen can make light-emitting diodes illuminate, Zhang Yuansong knows very well that the power consumption of light-emitting diodes is very low, and if this technology can be perfected and promoted, it will be a revolutionary breakthrough.

After Zhang Yuansong, who was still a little unhappy just now, heard Xu Hongwen's words, the unhappiness in his heart had already disappeared, and he asked a little eagerly: "Are you really sure that this technology can make light-emitting diodes achieve illuminated brightness?" ”

"Teacher, of course I can be sure, and the brightness of the real thing I have made is really amazing, and it is beyond imagination to save electricity!" As he spoke, Xu Hongwen took out an LED downlight from his bag, sent it to the teacher and said, "Teacher, this is the lamp pattern I have made!" ”

Seeing the silver-white metal lamp on the table, the well-informed Zhang Yuansong has never seen such a lamp, from the table xiàn to see that the material of this lamp shell should be aluminum, the appearance is round, he picked up this lamp pattern and looked at it carefully, the lamp shape is novel and has a sense of science and technology, the front is a round aluminum frame, but the middle is a white glass, and the light-emitting diode should be sealed inside.

Twisting the wires connected from the lamp, Zhang Yuansong was able to Xu Hongwen and said: "Do you still need to use transformer power supply for this lamp!" ”

Seeing the teacher's interest, Xu Hongwen hurriedly said: "The transformer power supply has been placed in the lamp shell, and now it can be directly connected to the power supply!" ”

There are a lot of wires in the room, Xu Hongwen found a few meters of wires to connect and plug them, and dropped the power in front of the teacher, and the LED lights emitted a bright white light, which suddenly illuminated the originally dim office as if it were day.

Zhang Yuansong, who was staring at the lamp, turned his head to avoid the dazzling light at the moment the lamp was on, his office was a 100-watt light bulb, and he usually felt that the brightness was okay, but when he was writing materials, he had a meeting to open a desk lamp, but now Zhang Yuansong saw that when the lamp was lit, the brightness of the whole office was sublimated, and this light was no longer the dim yellow of ordinary light bulbs, and the white light was as bright as the sun.

Zhang Yuansong glanced at his student, this lamp is no longer a sample of the real yàn room, regardless of the ingenuity of the lamp shell or the unique charm of the light, this lamp is already a mature product!

He really didn't expect Xu Hongwen to be able to do this in a short period of time, Zhang Yuansong, who saw his students having such achievements, was relieved, but reminded: "Hongwen, there is no patent application for this light-emitting diode technology, the market application of this technology will be very wide, and it must be patented as soon as possible!" ”

This old professor is still so selfless, Xu Hongwen didn't hide it from the teacher, and said directly: "Teacher, please rest assured, I went to Xiangjiang two days ago and have applied for an international patent, and I have also applied for a patent in China!" ”

Hearing this, Zhang Yuansong was relieved, he actually had a few big times on patents, two years ago Zhang Yuansong took a few new technologies to participate in an international seminar, because there was no awareness of patents, those few promising new technologies were stolen by small Japan, and then he failed to win the lawsuit, because the patent was applied for by small Japan first!

Zhang Yuansong, who was relieved, asked some technical questions before saying: "Hongwen, you can actually write a paper on light-emitting diodes, such a practical technical invention will definitely add points to the debate!" ”

Xu Hongwen, who had an idea in his heart, did not agree with the teacher's advice, he did not want to make this gold-absorbing technology public in the next few years, and the domestic patent protection is really worrying, if Xu Hongwen did not make much money from his technology in the end, it would not be a joke!

After talking about this, Xu Hongwen saw the budget report on the teacher's desk, glanced at it and asked, "Teacher, the budget report in the real room hasn't been cleared yet?" ”

Speaking of this budget report, Zhang Yuansong has a headache, the application for funds in the real room is a troublesome thing, as an academician of the Academy of Sciences, he will have a certain inclination in scientific research funds, but the budget report at the beginning of the year must be done in detail, although scientific research is planned in general, but in the process of research and development is sporadic.

For example, if a part of the equipment is broken, and the part just reaches a certain value, it must go through the school procurement procedure according to the regulations, but it can't be stopped for a long time in the middle of the process, and sometimes it has to be operated in violation of regulations, but the expense reimbursement after the illegal operation will become a problem!

There are also all kinds of high-performance chips for research, such chips are not produced in China at all, and the European and American manufacturers who produce these are prohibited from exporting such chips to our country because of the Batumi agreement, such chips cannot be obtained through formal channels at all, and you can only buy chips smuggled from the black market.

Thinking of this, Zhang Yuansong unconsciously rubbed his temples and said self-deprecatingly: "Hehe, this report is a fake account for people to see, and it has no supervisory role at all!" "Collecting!! Ask for a recommendation!! Ask for all kinds of comfort!! Thank you
