Chapter 566: Lightweight, strong, and low power consumption
Although Gao Zhendong felt that things were progressing smoothly, it would certainly not happen so quickly. Both sides had a lot of things to do before making a formal decision.

And Gao Zhendong himself obviously couldn't just wait for this one thing, he had a lot of other things to do.

There is good news, not from the inland, but from Hong Kong Island across the river.

On March 3, Gao Zhendong, who went back to his father-in-law's house to visit the old man, received something sent to him by Lou Shouxing.

Lou Shouxing delivered a package from Hong Kong Island, and in this package was a batch of red and green LED lamp beads. All their existing sizes and specifications were placed in it, and there were also dozens of 8-segment LED digital tubes, which were only red. In the same system, it is best to have two or more distinguishable colors for display prompts, but this is not necessary for displaying numbers.

In the package, Lou Shouxing also enclosed a letter, instructions for using the LED device and a tape.

In the letter, Lou Shouxing mainly talked about family matters, instructing Gao Zhendong to take good care of his sister and other daily matters as a brother-in-law. He also mentioned that his company in Hong Kong Island had trial-produced a batch of new components, which were quite interesting, and he specially asked his brother-in-law to appreciate them.

Is John Bull okay with this?

John Bull's attitude was rather subtle at first. How could they have any objection to this "light bulb" that couldn't even provide lighting? They were more than happy to sell this thing to us.

The GDP of Hong Kong Island is also GDP. Today, when the entire colonial system has been torn apart by the Russians and the Americans, they attach more importance to Hong Kong Island.

At the end of the letter, the origin of the tape was specifically mentioned.

"I am glad to hear that you are quite interested in Lucia-style music recently. However, it is inconvenient to carry it with you and you cannot listen to it whenever you want. So I have selected ten famous Lucia folk songs and converted them into cassettes to satisfy your needs."

Lucia, the core of the Russians.

Lucia's music was chosen in order to get it in. Western things are somewhat sensitive when they are brought in. It is unwise to alarm the National Defense Committee and ask for a green light just for this tape. This is not how you should use your privileges.

The reason for choosing Lucia folk music is that it can be released in Hong Kong Island. If it was something 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 into the computer, which were somewhat different from ordinary read instructions.

After receiving the command, the computer's tape reel gear turned rapidly, making a "hissing" sound and causing the tape to fast forward until it reached the position specified by Gao Zhendong, then the tape reel gear stopped turning fast.

The tape drive lowered its head and began to read data with a "click-click" sound.

Not long after, the file hidden in the middle of the tape was read out and stored in Gao Zhendong's computer memory.

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 took a look. After finding no problem, he operated the computer and deleted the original file on the tape.

That’s right, the main mission of this tape is to convey to Gao Zhendong some things that Lou Shouxing was not convenient to say in a letter.

He picked up the tape, walked out of the south room, and handed the tape to Lou Xiao'e who was cooking: "Here, this is the Lao Maozi folk music that Big Brother brought to you."

Lou Xiao'e took it happily and inserted it into the tape recorder. The melodious and cheerful "Katyusha" began to sound in the house - she really liked these old Russian folk music.

Gao Zhendong turned around and went back to the south room, carefully reading Lou Shouxing's encrypted letter.

There is actually not much content, it mainly talks about the situation of LED.

The core is actually one thing: the patents for red light LED and green light LED have been fully protected by them, and the patent for yellow light is being developed!
And because Gao Zhendong provided all the technology, it can be said that within 20 years, the LED patents were tightly protected.

Lou Shouxing is currently selecting several patent licensing partners from Citigroup, John Bull and other Western camps to authorize them to produce LEDs.

As for why he didn't produce everything by himself, Lou Shouxing was influenced by Gao Zhendong. If he produced everything by himself, he was afraid that others would turn the table.

Moreover, Zhenxing Electric's production capacity in Hong Kong Island is insufficient to cover the needs of all major countries. It would be better to release it to other countries, which would be more conducive for Zhenxing Electric to gain economic benefits and technological influence.

However, Lou Shouxing was not completely unprepared. After the yellow LED was about to be completed and patented, he was ready to keep it in the hands of Zhenxing Electric. You have two colors, which is enough. I will keep the yellow one.

At the end of the letter, Lou Shouxing mentioned something else.

"In the division of patent authorization regions, we have reserved patent authorization for the countries and regions of the Economic Assistance Association according to your request. It is up to you to decide how to use it."

The countries in the region of the Economic Cooperation Council and the Oceania Convention Organization cannot handle it on their own, and even the countries in the Economic Cooperation Council themselves may not be able to handle it.

But we can.

If this thing can only be produced by the Oceanic Treaty Organization countries, the Russians will imitate it without hesitation. Once the technology of red, yellow and green LEDs is made public, it will not be difficult to produce. Even if the Russians' semiconductors are not good, they will not be so bad that they cannot produce this thing.

But we can also produce and sell, which is another matter.

We still have to give face to the second brother, and he is also a very good fighter.

Brother-in-law is awesome! Gao Zhendong smiled. He took out a 12V lead-acid battery and a current-limiting resistor with great interest, connected it to an LED lamp and tried it out. The main factor that determines whether an LED is lit and its brightness is the current, so you will see that the same LED is used in both the 5V and 12V powered circuits. It's fine as long as it's not too outrageous.

Obviously, there won't be any problem and my brother-in-law can't afford to lose face.

The red and green lights lit up alternately, and even Lou Xiaoe stretched her head to take a look, "Wow, this thing is so beautiful."

People who are used to seeing LED diodes may not have that feeling, but people who are used to seeing incandescent lamps and oil lamps will really think it is beautiful when they see the chubby LED light up for the first time.

"Isn't it beautiful? It's made at home, haha." In front of Lou Xiao'e, there was nothing to hide.

"I know, I know. It's all thanks to you! Oh, and my brother also contributed a little bit."

I don’t know how Lou Shouxing felt when he heard this, but Gao Zhendong felt very happy anyway.

He started playing with the 8-segment LED digital tube. The reason why it has 8 segments is that the number "7" composed of 8 straight lines can display all the numbers. Add a decimal point and it becomes 8 segments.

It can even display some letters in a slightly abstract way, such as A, b, C, c, d, E, F, L, etc.

This is the most widely used type of LED digital tube. It has basically sufficient functions and is the cheapest. One byte can just store a single-digit segment code combination. The programming and circuit are simple.

So before Lou Shouxing left, Gao Zhendong specifically instructed that after the red LED was successfully developed, this thing should be made as soon as possible as it was urgently needed!

The room was filled with flickering red lights, illuminating Gao Zhendong's excited face.
-
The next morning, Gao Zhendong took some LED devices and went straight to the 12th Ministry of Machine Building with the excitement of a child showing off his new toys to his friends.

He did not go to the department leader, but to the chief engineer of the department. This thing was mainly a technical achievement, so he could just go to the chief engineer. It would not be good to go to the leader every time.

When the chief engineer of the department heard that Gao Zhendong was looking for him, he came immediately. This man would not come unless it was important. No matter whether he came for official business or his own personal matters, it was a big deal, even if he wanted to get married.

But he already has a wife.

As soon as Gao Zhendong saw him coming, he started to search his pockets.

Seeing Gao Zhendong's behavior, the chief engineer of the department was delighted, thinking that something good must have happened.

"Chief Engineer, I got a new component. Come on, let the department test it first."

"No, you are the chief engineer too. I don't dare to be called the chief engineer." The chief engineer of the department did not forget to make a joke and took the things from Gao Zhendong's hand while speaking.

When I opened the paper package handed to me by Gao Zhendong, I saw a bunch of cylindrical translucent components, some red, some green, and some square ones that looked like components that displayed numbers, with a total of 9 pins.

"This is?"

At this time, LEDs could not be used for lighting, because without blue LEDs, white light could not be emitted. Gao Zhendong only mentioned the most basic uses: "It can be used as an indicator light and digital display. Find someone to test it."

After hearing about this use, the chief engineer of the department immediately connected this thing with various thermoluminescent light-emitting elements. He discovered the first advantage of this thing - it does not contain any glass and is very strong.

"Hey, this thing is interesting. There is no glass at all. It looks like the filament is directly wrapped in this colorful plastic. Won't this plastic burn out?"

I had never seen a similar device, so according to my habit of thinking, I thought the light-emitting body inside was a filament.

Gao Zhendong didn't explain at first, but just shook his head: "No! Find someone else to try."

The chief engineer of the department looked at the things in his hand and the instruction manual. This was Gao Zhendong's usual style.

Since Gao Zhendong was so excited, this thing must be something extraordinary. He called the technicians and handed the thing to them: "Let's go test this thing."

The testing of these things is actually very simple. There are only a few parameters and no particularly difficult items to test. Some special items are meaningless to the user and can be put aside for later.

Dozens of minutes later, the technical staff in the department came with the test report, looking surprised.

"Chief Engineer, this thing is great! I want to get some to play with myself."

"Be more specific."

"Low power consumption, strong, light and small, and highly reliable! These four points are enough."

The technicians were very excited, as this was a new component.

As for the digital tubes, they didn't feel anything for the time being because they were not familiar with digital circuits and did not realize how useful this thing was for digital circuits.
