Hand rubbing nuclear fusion live in the wilderness

Chapter 198 Light Exploration Mission Completed

The square glass mirror is about one meter long and half a meter wide.

Placed horizontally on a silver-white metal laboratory table, it can clearly reflect the surrounding situation, and its effect is no worse than that of a mirror produced by a modern factory.

Han Yuan looked at it, and what caught his eyes was a strange face.

After being stunned for a moment, he finally realized that this strange face was made by him during the first live broadcast.

It's just that there is no such thing as a mirror in the simulated space, and he is not familiar with it.

Looking at the unfamiliar face, Han Yuan shook his head and placed the mirror on the wall of the chemical laboratory, cleaned the laboratory and returned to the living room.

Now he has produced three different optical devices: concave lens, convex lens and mirror.

According to the requirements of the optical exploration mission, it is only necessary to record the relevant data to judge whether the three different optical devices meet the requirements of the system.

If so, then this task will be completed soon.

Back in the workshop, Han Yuan took out a pen and paper, and recorded the manufacturing process of the concave-convex lens and the mirror, as well as some related principles and information.

An hour passed, the sky dimmed, and Han Yuan stopped writing.

Compared with other things, these three optical devices need to record much less data.

After checking the information, he reopened the task information panel.

[Task Requirements: To manufacture five optical devices with different functions and conduct related explorations during the current second-level task time, and record the process and complete information, the current progress (3/5). 】

"Not bad, it really works."

Seeing that the current progress has changed from (0/5) to (3/5), Won's eyes brightened and a smile appeared on his face.

It seems that this task will be completed soon.

After getting up, Han Yuan glanced at the sky that had not yet completely darkened, and returned to the chemistry laboratory.

Now that three have been completed, according to this method, he is going to complete this task tonight.

In the chemical laboratory, under the bright lights, he was busy for two or three hours. Han Yuan manufactured two optical devices for different purposes, and then returned to the studio to record the relevant information.

When the data record is complete, the system's prompt sounds simultaneously in the mind.

"Ding, the information has changed."

"Ding, congratulations to the host for completing the 'Light' exploration mission."

"Since the birth of the first ray of light in the vast universe, it has been the yearning of life and the hope of the universe."

"Task requirements: manufacture five optical devices with different functions and conduct related explorations during the current second-level task time, and record the process and complete information, the current progress (5/5)."

"Task Reward: Elementary Optics Application Knowledge Information (issued)."

The sound of the system's upgrade sounded in his mind, and Han Yuan also felt a little touched.

The 'Light' exploration task is the fastest one of all his tasks.

It took less than [-] hours from triggering the task to finally completing and obtaining the reward.

After obtaining the elementary optical application knowledge information, Han Yuan flipped through the technology inside.

Basic optical application equipment such as magnifying glasses, telescopes, and microscopes contain relevant principles and manufacturing knowledge information.

Although it only took a few hours to obtain this primary optical application knowledge information, its quality is no different from other primary knowledge information.

After looking at the technology inside, Han Yuan turned around and was about to finish writing the unrecorded data in the magnetic storage.

Suddenly, a thought flashed in his mind, he straightened up, and started to search again in the primary optics application knowledge information.

"Cool fluorescent lamps."

This is the target of his search this time. It can be used for a part of the display. It belongs to optical technology application equipment. If there is no problem, it should be included in the primary optical application knowledge information.

Originally, Won was going to use 'ray picture tube' to make display screens.

But now, there seems to be a better option.

After a while, through simulated search terms, Won found what he was looking for.

In addition to 'cold fluorescent lamps', he also found another technology 'fluorescent diodes' that can be used to make display screens.

Like cold fluorescent lamps, fluorescent diodes can also be used to make display screens.

But the structures of the two are quite different.

"Cold cathode fluorescence, commonly known as CCFL, uses phosphors of three primary colors."

"Nickel, tantalum, zirconium and other metals are usually used as cold cathodes, and a glow discharge can be formed under a high starting voltage to make the lamp work."

"It belongs to a part used in the second-generation display."

"And fluorescent diodes are different. Fluorescent diodes are also called light-emitting diodes, or LEDs for short."

"It is a commonly used light-emitting device in modern electrical appliances. It releases energy and emits light through the recombination of electrons and holes, which can efficiently convert electrical energy into light energy."

"A technology that belongs to the application in the three generations of displays."

As for the 'ray picture tube' he wanted to make earlier, that was the light-emitting part used in a generation of monitors.

It is a kind of crystal tube, and it is a technology in the knowledge information of intermediate electric energy applications.

Although the 'ray picture tube' can also be used to manufacture display screens, its volume, weight, and high power consumption make the displays it produces extremely heavy.

And more importantly, the ray picture tube can only display black and white.

The display screen made of this kind of parts has a very famous name when it is applied to electrical appliances: "black and white TV."

At present, in human society, ray display tube displays have basically been replaced by LED liquid crystal displays.

The old black and white TVs are almost invisible.

After finding the information, Han Yuan was not in a hurry to check it, but first recorded the unfinished magnetic storage information, and then looked through the information under the moonlight, and wrote down some things with a pen from time to time.

After all, 'cold fluorescent lamp' and 'fluorescent diode' belong to the same new technology for him, and he has never been exposed to it before.

If he wants to use these two technologies to manufacture displays, he must first understand and understand each step before he can do it.

But it's worth it, even if it's worth delaying making displays for a few days.

Time passed bit by bit, the moon climbed up the dome, Han Yuan woke up from the state of concentrating on studying, and glanced at the clock on the wall.

More than two in the morning.

Seeing the time, Han Yuan was slightly shocked. He didn't expect the time to pass so quickly, and several hours passed in the blink of an eye.

However, the harvest in these few hours is not small. Although I have not fully understood and digested the manufacturing methods and principles of "cold fluorescent lamps" and "fluorescent diodes", I have understood a lot.

It is estimated that one or two more nights like this will be almost the same.

After thinking for a while, Han Yuan put away the materials and prepared to wash up and go to bed. There will be a live broadcast tomorrow, and it is already late.
