Chapter 566: Light, compact, strong and low power consumption
Although things are going very smoothly in Gao Zhendong’s opinion, the speed of all this will definitely not be that fast. No matter which party has made a formal decision, Less things to do.
As for Gao Zhendong himself, it is obviously impossible to just wait for this one thing. He still has many things to do.
There is good news, not from the mainland, but from Hong Kong Island across the river.
On March 26, Gao Zhendong, who returned to his father-in-law’s home to visit the old man, received something sent to him by Lou Shouxing.
Lou Shouxing sent a package from Hong Kong Island, and inside this package was a batch of red and green LED lamp beads. All their current sizes and specifications were put in it, as well as dozens of 8-segment LED lamps. No matter, this thing is only red. In the same system, it is best to have two or more distinguishable colors for display prompts, but it is not necessary to display numbers.
In the package, Lou Shouxing also included a letter, instructions for using the LED device and a tape.
In the letter, Lou Shouxing mainly talked about family matters. He told Gao Zhendong to take good care of his sister and other daily life as a brother-in-law. He also mentioned that his company in Hong Kong Island had trial-produced a batch of new components. It was quite interesting and deliberately Ask your brother-in-law to taste it.
Want to ask John Bull if he has any objections to this?
John Bull's attitude at this time was rather subtle. If they had any opinions about this "light bulb" that was terrible at lighting, they were eager to sell it to us.
The GDP of Hong Kong Island is also GDP. Today, when the entire colonial system has been torn to pieces by the joint efforts of Lao Maozi and Citigroup, they pay more attention to Hong Kong Island.
At the end of the letter, he also specifically mentioned the origin of the tape.
“I’m glad to hear that my little sister is very interested in Lucian style music recently, but due to the inconvenience of carrying it around, I can’t listen to it at any time, so I specially selected ten famous Lucian folk songs and converted them into tapes to satisfy my little sister’s needs. ”
Lucia, the main core of Lao Maozi.
The purpose of choosing Lucia’s music is to gain entry. Western things are a bit sensitive to come in. It is unwise to alert the National Defense Work Committee to give the green light just for this tape. This is not the way to use privileges. .
The reason why I chose Lucia Folk Music was to be able to play Hong Kong Island. If there was a song like "Unbreakable Alliance", I'm afraid Lou Shouxing would have a lot of fun.
Gao Zhendong and Lou Xiaoe returned home, and Gao Zhendong put the tape into the computer's tape storage.
He entered several instructions on the computer, which were a little different from ordinary reading instructions.
After receiving the instruction, the computer's take-up gear rotated rapidly, and the "sizzle, sizzle, sizzle" controlled the tape to advance rapidly. It did not stop the rapid rotation of the take-up gear until it reached the position specified by Gao Zhendong.
The tape drive lowered its magnetic head and began to read data with a creaking sound.
Not long after, the file hidden in the middle of the tape was read out and stored in the memory of Gao Zhendong's computer.
Gao Zhendong used decryption software to decrypt the file. The file was not long and the decryption was completed quickly. Gao Zhendong opened it and looked at it. There was no problem before operating the computer and deleting the original file on the tape.
Yes, the main mission of this tape is to bring to Gao Zhendong some words that Lou Shouxing was not comfortable saying in the letter.
He picked up the tape, walked out of the south room, and handed the tape to Lou Xiao'e who was cooking: "Here, the old Maozi folk music that big brother brought to you."
Lou Xiao'e took it happily. , inserted it into the tape recorder, and the melodious and cheerful "Katyusha" began to play in the room - she really liked these old Maoist folk music.
Gao Zhendong turned back to the south room and carefully read Lou Shouxing's encrypted letter.
The content is actually not much, it mainly talks about the situation of LED.
The core is actually one thing. The patents of red LED and green LED have been fully protected by them, and the yellow LED is being worked on!
And because Gao Zhendong has all the technology, it can be said that within 20 years, LED patents will be protected airtight.
Lou Shouxing is selecting several patent licensing partners from Citigroup, John Bull and other Western camps to authorize them to produce LEDs.
As for why he doesn't produce everything by himself, Lou Shouxing is influenced by Gao Zhendong. If he produces everything by himself, I'm afraid people will overturn the table.
Furthermore, on Hong Kong Island, the production capacity of Zhenxin Electric is still insufficient to cover the needs of all major countries. It is better to release it, which will be more conducive to Zhenxin Electric's ability to seize economic benefits and technological influence.
However, Lou Shouxing is not defenseless at all. After the yellow LED that is about to be completed is patented, he is ready to take it into Zhenxing Electric's own hands. You have two colors, and the yellow one is enough. I keep it.
At the end of the letter, Lou Shouxing mentioned something.
“In the division of patent authorization areas, the patent authorization for the national regions of the Economic Assistance Association has been specially left as per your request. It is up to you to decide how to use it.”
In the area of the Economic Assistance and Assistance Assistance Association, the Ocean Convention countries themselves cannot get it right, and even the Economic Assistance Association countries themselves may not be able to get it right.
But we can.
If this thing can only be produced by the Oceanic Treaty Organization countries, then Lao Maozi will not hesitate to imitate it. Once the red, yellow and green LED technology is made public, it will not be difficult, even if Lao Maozi Semiconductor fails , but it won’t be so broken that it can’t even be produced.
But we can also produce and sell it, which is another story.
The second brother still needs to be given face, and this second brother is also very good at fighting.
Brother-in-law is awesome! Gao Zhendong smiled. He took out a 12V lead-acid battery and current-limiting resistor with great interest, connected it to the LED light and tried it. The main factor that determines whether the LED lights up and its brightness is the current, so you will see the same LED, 5V power supply circuit It is also used, and the 12V power supply circuit is also used. Don't be too outrageous and it will be fine.
Obviously, there will be no problem, and the brother-in-law cannot afford to lose face.
The red light and the green light light up alternately, and even Lou Xiaoe stretched out her head to take a look, "Ah, this thing is so beautiful."
People who are used to seeing LED diodes may not feel that way. , but for people who are used to incandescent lamps and oil lamps, when they saw the fat LED glowing for the first time, they really thought it was beautiful.
"Isn't it beautiful? Our family makes it, haha." In front of Lou Xiao'e, there is nothing to hide.
"I know, I know, it's all your credit! Oh, by the way, big brother is a little bit too."
I don't know how Lou Shouxing felt when he heard this, anyway, Gao Zhendong It sounds pretty cool.
He played with the 8-segment LED digital tube again. The reason why it is 8-segment is because a number "8" composed of 7 straight lines can display all numbers. Adding a decimal point, that is It’s 8 paragraphs.
It can even display some letters slightly abstractly, such as A, b, C, c, d, E, F, L, etc.
This is the most widely used LED digital tube. Its functions are basically sufficient and the cheapest. One byte can just store a one-digit segment code combination. The programming and circuit are simple.
So before Lou Shouxing left, Gao Zhendong specifically told him that after the red LED was successful, he would get this thing out as soon as possible for urgent use!
The red light flashed in the room, illuminating Gao Zhendong's excited face.
——
The next morning, Gao Zhendong brought some LED devices and went straight to the 12th Machinery Department with the excitement of a child showing off a new toy to his peers. .
He did not find the department leader, but the department chief engineer. This thing is mainly a technical achievement, so just go to the chief engineer, and it is not good to go to the leader again and again.
Hearing that Gao Zhendong was looking for him, the chief engineer of the department came immediately. This person would not come to the door unless there was no big deal. Whether he came for official business or his own private matter, it was a big deal, even for him I want to find a wife.
But he already has a wife.
As soon as Gao Zhendong saw him coming, he started to pick his pockets.
Seeing Gao Zhendong's battle, the chief engineer of the department was happy, and it was determined that something good was going on.
"Chief engineer, I got a new component here, come on, come on, let the department test it first."
"No, you are also the chief engineer. I don't dare to call me chief engineer." The chief engineer didn't forget to make a joke, and took the things from Gao Zhendong's hand while talking.
Opening the paper package handed over by Gao Zhendong, I saw a bunch of cylindrical translucent components, some red, some green, and a few square ones that looked like numbers. The component has a total of 9 pins.
"Is this?"
At this time, LEDs could not bear the lighting task, because without blue LEDs, they could not emit white light. Gao Zhendong just said the most basic use: " It’s used for indicator lights and digital displays. Ask someone to test it.”
After hearing about this use, the chief engineer immediately connected this thing with various thermoluminescent light-emitting components. He discovered the first benefit of this thing - it has no glass at all and is very strong.
"Hey, this thing is interesting. There is no glass at all. It seems that the filament is directly wrapped in this colored plastic. Won't these plastics burn out?"
I have never seen anything like this. device, so based on my thinking habits, I thought the luminous body inside was a filament.
Gao Zhendong did not explain at first, but just shook his head: "No! Find someone to try."
The chief engineer of the department looked at the things in his hands and the instructions. This is also Gao Zhendong. The consistent style.
Since Gao Zhendong is so excited, this thing must not be simple. He called the technicians and handed the things to them: "Let's go and test this thing."
The testing of these things is actually very simple. Yes, there are only a few parameters, and there are no particularly difficult items to test. Some special projects are meaningless to the user and can be discussed later.
Ten minutes later, the technicians from the ministry took the test report with a look of surprise on their faces.
"Chief Engineer, this thing is okay! I want to get some for my own play."
"Be specific."
"Low power consumption, strong, light and small, and high reliability! These four points are enough."
The technicians looked excited, this is a new component.
As for the digital tube, they didn't feel it for the time being, because they were not familiar with digital circuits and did not realize how useful this thing is for digital circuits.
