To make LED lamps, of course, you can’t do it all in reality, because that’s too difficult.

　　Through the system, a lot of minutiae materials can be saved, which is a great convenience for Ankai.

　　The most important thing is the electrical parts, which can replace the original chip of the LED lamp. This chip is very troublesome to manufacture.

　　 Normally, the chip is composed of gold pad, P pole, N pole, PN junction and back gold layer. The wafer is a PN combination composed of P-layer semiconductor elements and N-layer semiconductor elements rearranged and combined by the movement of electrons. It is this change that enables the wafer to be in a relatively stable state. When the wafer is applied with a certain voltage to the forward electrode, the holes in the forward P area will continuously swim to the N area, and the electrons in the N area will move to the P area relative to the holes. While the electrons and holes move relative to each other, the electrons and holes pair with each other to excite photons and generate light energy.

　　 Take a look, I know every word, and I don’t know what I’m talking about in combination.

　　 If this is really done according to reality, An Kai will just live the days when he can’t see his fingers. What kind of lights are there.

　　 Fortunately, with the system, universal parts such as electrical parts can be converted into chips. As for other brackets, silver glue, gold wire and resin, etc., it is easy to handle.

Needless to say, the so-called silver glue is actually white glue, which plays the role of conducting and bonding. It is mainly replaced by silver powder, resin and thinner. If the resin is used, it can be made with plastic and rubber. What is the principle? I don't know, anyway, the system says it can.

　　Silver powder is also easy to say, the shelter has silver, both silver and gold. In the early days of the shelter, these things were useless.

　　 is not really useless, but not useful.

　　 Those silly and cumbersome equipment still don’t need such delicate things, so the precious metals such as gold and silver that were found in the process of repeated searches have been left behind, and it is just right to use it at this time.

　　 Thinner can be completely eliminated, the system naturally has the power to stir all kinds of materials together, this does not need Ankai to worry about.

　　 And the last epoxy resin is composed of two kinds of glue.

　　Glue A is the main agent, which is composed of epoxy resin, defoamer, heat-resistant agent, and diluent; agent B is a curing agent, which is composed of acid, release agent and accelerator.

　　 How do you say, the seemingly simple resin is actually the most complicated, mainly because there are too many kinds of materials, and many Ankai have never heard of it.

The convenience of the system is that many auxiliary materials can be directly erased. As long as the basic materials are provided, assembly and fusion can be carried out out of thin air, eliminating many processes, which makes Ankai much more convenient .

　　 However, considering the composition mode of LEDs, etc., there are a lot of electrical parts that need to be used. Many broken lamps were removed. As a result, only five sets of light panels were made in one pass.

　　 There must be a group in the living room, which is related to daily life. If there is no light at all, this day can still be passed.

　　 There is also a group for the restaurant, one for the passage, one for the training room, and one for the elevator.

　　 As for the cold storage, the study room, the broadcasting room, etc., this is nothing. These are rooms that are not important or need light. When the lamps are not sufficient, their status can only be retired and retired.

　　 This is also a helpless choice.

　　 Even the current five sets of light panels are actually not enough. For a relatively large suite like the living room, the light panels can only illuminate the area of ​​the living room. As for the bedroom, it is completely useless.

　　 Fortunately, the bedroom is mainly used for sleeping, even if you are doing errands, you can fumble around with a black light, so it's not a big problem.

　　 In addition to lamps, there are many other damaged facilities.

　　Important, such as mines and water purifiers, this must be supplemented. And only if the materials are enough, more equipment can be made.

Including electrical parts, originally it could only be obtained by disassembling electrical appliances, but as Ankai put down the ordinary workshop, the production line inside can also be used to produce electrical parts. The materials are also more complicated, but there is no such rare material. , So Ankai can make it by himself.

It’s just that the shelter’s demand for materials is getting higher and higher, and he is unwilling to use materials for electrical parts. Unless some important equipment is broken and there is not enough material to supplement, he will choose to make it himself. Electrical parts.

　　 Otherwise, you can endure it, and the deterioration of the quality of life is only temporary.

　　 Everyone has no complaints about this. After all, it is very lucky to be able to live well, and no one is so ignorant that Ankai should guarantee their quality of life.

　　 Reluctantly replenished the important equipment in the shelter, Ankai picked up a lot of materials, carefully inspected all the equipment, and repaired the ones that were not too durable anymore.

　　 This job alone took him three days.

　　 Fortunately, the first batch of equipment was broken in time, and he immediately discovered the problem with the sun lights.

　　The first solar lamp produced was only a period of time later than ordinary lamps, but the difference is that the solar lamp was fully turned on almost 24 hours a day, so it was more worn out. If Ankai hasn't checked it now, it is estimated that within a week, a large number of sun lamps will be directly damaged. Then it will be really painful, and it will directly affect the growth of crops. Now I can make up for it, thanks to the first batch of broken equipment.

　　 After all these problems were dealt with, An Kai went back to the fifth underground floor and continued to dig the tunnel.

　　 The work of digging tunnels is said to be fast or not, but it is not too slow.

　　 just involves a lot of energy.

　　 When it comes to physical fatigue, it really doesn’t matter.

With an average progress of two to three hundred meters per day, Ankai has dug several kilometers in just one month. UU Reading www.uukanshu.com, but compared to the 100-kilometer plan, there is still a big deal. gap. But for now, building a rising platform should be enough.

　　 Ankai wondered before, whether to build a liftable platform specifically for transporting vehicles.

　　 Prior to this, the vehicle had been stored in the garage. In fact, it was very convenient to get in and out, and it was not a hassle.

　　 But it took a lot of effort to get the newly manufactured vehicle out. He even had to open up a special passage and then set up a large elevator to release the powered caravan.

The 　　 powered caravan is only the lowest level among all system vehicles. It is also the smallest and lightest, so it is naturally easy to transport. This kind of temporary embracing method barely works. But what if you want to build large trucks and rotorcraft in the future? Even in the future, military vehicles may be used, such as armored vehicles, tanks, real helicopters, etc. Is this method still used?

　　 So a well-shaped passage, plus a lifting platform, becomes very necessary. And for the convenience of entry and exit, and manufacturing convenience, the manufacturing workshop of the vehicle and part of the material library should also be placed here.

This plan is slightly smaller than the base, but overall it is still very large. What Ankai is now struggling with is to dig the subway all the way to the base, or to build a transfer station here and give the channel well. Get it out.

　　 This is really a sad choice.
