After LED lights are launched on the market, they need to continue research, which is inevitable. For Long Jianhua's team, only the basic principles are studied, that is, the design of double heterostructures, improving brightness, branch coatings, and appearance will be carried out by a professional team.

Zheng Yichun had worked as a technician in a chemical company and was quite eager for production management. Therefore, after the project was completed, he planned to go to the lighting company.

Long Jianhua also readily agreed to his request. He likes production management and has shown certain abilities in this regard. He is also recruiting outside. He has worked here for four years and is a person who knows the truth. Why not do it?

Next, Long Jianhua was nailed to the research institute, watching them apply every day, looking for the most advanced smear technology. Half a month later, Zheng Yichun installed the applied lamp tube, then pushed it away, looked at Long Jianhua with expectant eyes, "Mr. Long, are you here to turn on the power supply?"

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

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

The last inspection was four days ago, when the 12-watt LED reached the level of 40-watt incandescent lamps, but Long Jianhua said it was not possible. He had to continue to do it. It was only successful when it reached 60 watts. The blue light was one hundred times that of the previous one, and the white light had to be up to the next level.

Laboratory and large-scale industrial production are still different. Most of them are manually operated here. If the techniques are slightly unstable, the results may vary.

They thought 40 watts were already very good, but Long Jianhua didn't think so. After modifying the ratio, he applied three lamps to the test today.

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

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

Yan Zuoqiu exclaimed, "Brighter than 40 watts!"

Long Jianhua narrowed his research and looked at the light source, and he wanted to brighten it. I wonder if it reached 60 watts.

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

In the hazy, he heard Qi Hao's scream, "More than 60 watts, less than 75 watts! Success! Hurry up, try those two!"

Yan Zuoqiu immediately asked, "That is to say, the brightness of this twelve watts is equivalent to that of a 75 watt incandescent lamp?"

Qi Hao laughed and said, "That's it!"

Long Jianhua turned around and said to Yan Zuoqiu, "Go and find some yttrium aluminum garnet powder. If you don't have it, buy some to grind it into powder and make it into phosphor."

He suddenly remembered that the white LED lamp he had "used" was made of yttrium aluminum garnet phosphor. He used to remember the achievements of the scholar from the island Japan, but he forgot about this.

Looking at Yan Zuoqiu's dazed look, Zheng Yichun said, "It can be found in the shops that produce fake diamonds, and some chemical shops."

Yan Zuoqiu said "Oh", "No wonder some diamonds are so cheap. They turned out to be used to produce fake diamonds."

Long Jianhua patted his forehead. This guy, what's the matter?

Seeing his actions, 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 and the other two, "I think this is not necessarily the best way. The phosphor made of yttrium aluminum garnet is also yellow."

Zheng Yichun immediately reacted, "If feasible, the production process will be much simpler and the cost will be reduced, and it will be one step closer to launching it to the market."

He has been engaged in production. In large-scale production, the pursuit of minimalism is minimalism, and it is not complicated if it can be complicated. The more complex the production process, the longer the process may be, and there will be more guarantee measures. Between the coating process and the phosphor process, it is obvious that it is easier to make phosphor.

Long Jianhua nodded, "In the past, we considered the most sodium compounds, as well as yellow phosphorus and phosphides, and it was a big omission without considering this aspect."

Shi Liqiu and Qi Hao were still working on the second LED light. Although they were still very excited on their faces, after Long Jianhua proposed another idea, their mood began to calm down...

The second one is equivalent to 75 watts; the third one is less than 75 watts. It exceeded the experimental expectations and was successful.

Looking at the three people who didn't have many excited expressions, Long Jianhua smiled and said, "This data is already our best. If it is industrial production, it will be higher than this. It can be said that this is successful and is ahead of our competitors."

"But my goal is industrialization, it is the market. If consumers want to buy, they must give them additional benefits, that is, the cost-effectiveness is beyond their expectations."

"The current energy-saving lamps, 20 watts are equivalent to 75 watts of incandescent lamps; ours is 12 watts, and the cost is twenty times that of energy-saving lamps, which means there will be no large market. Therefore, we must scale up and try our best to reduce non-material costs."

He often instills this concept with them. Even if he wants to go to the market, he must think about consumers. Only when consumers recognize it can they decide whether the product research and development is successful.

Suddenly, the corners of his mouth were raised and he turned to the door. When he was at the door, he turned to the three of them and said, "Within two weeks, write these patents and make as complete as possible protective patents. Just let Yan Zuoqiu do the experiment on yttrium aluminum garnet alone."

There are not only three of them who write a patent, but also a patent office, where nine people are still there.

The structure of the institute has been standardized now, and the departments that were not available but necessary were established one by one, and the Patent Office is one by one. The Patent Office is responsible for the writing and guidance of the patents, patent filing, and patent transactions of the institute.

Watching Long Jianhua leave, Qi Hao laughed and said, "Mr. Long should have thought of something good."

Zheng Yichun nodded, "The last time Mr. Long showed this expression, the island Japan immediately proposed that proposal, and it turned out to be the target of public criticism. I wonder who will suffer again this time."

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

Zheng Yichun patted his shoulder, "Brother, you are really only suitable for scientific research... Let's go, write a patent."

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

"The reason we need to patent energy-saving lamps is because we want to set up a lighting group that not only produces energy-saving lamps, but also produces white LED lamps."

For such things, he only talks about one direction, and they have to do the specific things.

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