After LED lamps are introduced to the market, it is necessary to continue research. For long Jianhua, the team has only studied the basic principle, that is, double heterostructure, brightness enhancement and branch coating. The shape design will be carried out by a professional team.


    Zheng Yichun had worked as a technician in a chemical enterprise and was longing for production management. Therefore, after the completion of this project, he planned to go to the lighting company.


    Long Jianhua also readily agreed to his request. He likes production management and shows certain ability in it. External recruitment is also recruitment. He has worked here for four years and belongs to people who know the root and the bottom. Why not?


    Next, long Jianhua nailed it to the Research Institute and watched them smear and find the most advanced technology every day. Half a month later, Zheng Yichun installed the painted lamp, then pushed it away and looked at long Jianhua with expectant eyes, "President long, you come to power?"


    Qi Hao looked at the lamp nervously and said, "the luminous intensity tester has been calibrated, the zero position has been adjusted, and everything is normal."


    Then he said, "this time, we must reach the level of 160 watts, so we will succeed."


    The last test was four days ago. At that time, the 12 watt led reached the level of 40 watt incandescent lamp, but long Jianhua said no. We must continue to do it until 60 watts. Blue light is a hundred times as much as before, and white light has to go up to a higher level.


    Laboratory and large-scale industrial production are still different. Most of them are manual operation. If the method is slightly unstable, there may be differences in results.


    They think that 40 watts is already very good, but long Jianhua doesn''t think so. After modifying the proportion, they coated three light tubes to have today''s test.


    Long Jianhua looked at the two of them and glanced at Yan zuoqiu and Shi Liqiu who had just come in. "Whether it is successful depends on my finger."


    As he said that, his right index finger pressed down, and the white light filled the laboratory with a sound of "click".


    Yan zuoqiu exclaimed, "brighter than 40 watts!"


    Long Jianhua squinted at the light source. It should be brighter. I don''t know if it has reached 60 watts.


    Suddenly, he remembered something. It seemed that the direction was wrong. This was not the final form of white LED, but just a transition


    Hazy, he heard Qi Hao''s exclamation, "more than 60 watts, less than 75 WATTS! succeed! Come on, try those two! "


    Yan zuoqiu then asked, "that is to say, the brightness of this 12 watt incandescent lamp is equivalent to 75 WATTS?"


    Qi Hao laughed and said, "yes!"


    Long Jianhua turned to Yan zuoqiu and said, "look for some yttrium aluminum garnet powder. If you don''t, you can buy some ground powder to make phosphor."


    He suddenly remembered that the white LED lamp he "used" used yttrium aluminum garnet phosphor. I used to remember the achievements of the scholar in Japan, but I forgot this.


    Looking at Yan zuoqiu''s stunned appearance, Zheng Yichun said, "there are all those shops that produce fake diamonds, and some chemical shops."


    Yan zuoqiu said, "no wonder some diamonds are so cheap. They are used to produce fake diamonds."


    Long Jianhua patted his forehead. This guy, think of those things so much?


    Seeing his action, Yan zuoqiu smiled awkwardly, "I didn''t react. I''ll buy it now. If I can''t buy it, please send it to the general hospital."


    After he ran out of the laboratory, long Jianhua said to Zheng Yichun, "I don''t think this is the best way. The phosphor made of yttrium aluminum garnet is also yellow."


    Zheng Yichun immediately responded, "if it is feasible, the production process will be much simpler, the cost will be reduced, and it is one step closer to the market."


    He was in charge of production. In mass production, the pursuit is minimalism. If it is not complex, it is not complex. The more complex the production process, the longer the process may be and the more safeguard measures will be taken. Between the coating process and the phosphor process, it is obviously easier to make phosphor.


    Long Jianhua nodded. "In the past, we considered the most sodium compounds, as well as yellow phosphorus and phosphides. It was a big omission not to consider this aspect."


    Shi Liqiu and Qi Hao are still working on the second LED lamp. Although they are still very excited, long Jianhua put forward another idea, and their mood began to calm down


    The second, equivalent to 75 WATTS; Third, less than 75 WATTS. It exceeded the experimental expectation and succeeded.


    Looking at the three people without many excited expressions, long Jianhua smiled, "this data is already our best. If it is industrialized production, it will be higher than this. It can be said that this is successful and ahead of our competitors. "


    "But my goal is industrialization, the market. If you want consumers to buy, you must give them additional benefits, that is, the cost performance should exceed their expectations. "


    "In today''s energy-saving lamps, 20 watts is also equivalent to 75 watts of incandescent lamps; Our is 12 watts, and the cost is 20 times that of energy-saving lamps, which means there will not be a large market. Therefore, we should scale up and try our best to reduce the cost of non materials. "


    He often inculcates this concept with them. Even if you want to go to the market, you should think about consumers. Only when consumers approve, can you decide whether the product research and development is successful.


    Suddenly, the corners of his mouth tilted and turned to the door. At the door, he turned and said to the three of them, "write these patents in two weeks and complete protective patents as much as possible. Let Yan zuoqiu do the experiment of yttrium aluminum garnet alone. "


    Writing patents, not only the three of them, but also a patent office, where there are nine people.


    Now the structure of the research institute has been standardized, and the necessary departments that did not exist before have been established one by one, and the patent office is one of them. The patent office is responsible for the patent writing guidance, patent application and patent trading of the Research Institute.


    Seeing long Jianhua leave, Qi Hao said with a smile, "long should think of something good."


    Zheng Yichun nodded, "President long showed this expression last time. The Japanese island immediately put forward the motion, which became the target of public criticism. I don''t know who will suffer this time. "


    Shi Liqiu said in surprise, "no? Our experiment exceeded the expected level. Isn''t it normal to smile? "


    Zheng Yichun patted him on the shoulder. "Brother, you are really only suitable for scientific research... Let''s go and write patents."


    Long Jianhua came to the office and called Fu Keping, director of the patent office, "now I give you a task to buy the patents related to energy-saving lamps. Of course, we can also exchange our white LED lamp patents. "


    "The reason why we want energy-saving lamp patents is that we want to establish a lighting group to produce not only energy-saving lamps, but also white LED lamps."


    For such things, he only talked about one direction, and the specific things had to be done by them.


    Fu Keping nodded, "I''ll do it now. If we can''t do it here, we''ll ask the general hospital for help. "


    Long Jianhua didn''t care about these specific operations. He nodded, "hurry up and do it well within six months."
