In Li Longji's dormitory, Ang Lee installed a variety of styles of light bulbs, including warm and romantic pink light bulbs, warm orange light bulbs, fantastic blue light bulbs, and even more powerful light bulb color boxes. Pen % fun % Pavilion www.biquge.info

The so-called bulb color box, is made of fine copper wire, small wooden edge and translucent silk with beautiful patterns, composed of a small box, is hung overhead, the area is relatively large, this is actually the deformation of the palace lamp, and the principle of the palace lamp is very similar, but the area is larger, the thickness is flatter, in later generations called ceiling lamp.

Such a ceiling lamp, after the bulb is lit at night, will become extremely beautiful, the light will illuminate the pattern on the silk, and it will be more beautiful than usual, especially when lying on the couch, as soon as you open your eyes to see the beautiful bright pattern, how comfortable and comfortable it feels.

After all the lamps were installed in place, Li An asked the little eunuchs to close all the curtains, and he wanted to see the effect of the lighting arrangement.

After all the curtains were closed, Ang Lee began to experiment with the effects of the lights one by one.

When the pink light bulb is turned on, the whole room is filled with romantic and warm pink, when the orange light bulb is turned on, the whole room becomes brighter, and when the blue light is turned on, standing in the room is like standing by the sea, the mood is calm and comfortable, and after the light bulb color box is turned on, the room is even more beautiful.

When all these bulbs are turned on at once, the room is as bright as daylight.

"Li Shilang, the effect of this light is so good, Your Majesty will definitely be happy, and there will definitely be a reward when the time comes."

Seeing the fruits of their labor, so brilliant, all the craftsmen were very happy.

"There is no shortage of rewards for this official, you guys are bent on rewards! You can rest assured, as long as you work hard, in the future, your rewards will be indispensable, and this time, this official will also show your majesty and help you get a reward. ”

Ang Lee opened his mouth to assure and encouraged the craftsmen to continue to work in order to do their work perfectly.

As soon as these craftsmen heard that there was a reward, they immediately worked harder, after all, the better they worked, the more rewards they would get, and if there was anything that they didn't do well, Li Longji would be unhappy, and maybe the reward would be gone.

In addition to supervising the craftsmen to work, Li Ang also found many eunuchs, taught them to use and replace light bulbs, and let them operate them on the spot, so that they could really learn this very low-level technology.

And Li An insisted on letting the eunuch learn to change the light bulb because the light bulb has a service life, and if it breaks, it will definitely need to be replaced, and it is obviously not suitable to let the craftsman go to the emperor's bedroom to change the light bulb, and let the eunuch change the light bulb, there is no such problem, and the eunuch is only slightly disabled, and there is no big problem with the mind and IQ, and it is absolutely appropriate to learn to change the light bulb.

In addition, in addition to letting these eunuchs learn to change light bulbs, Li An also had to set up a special electrician team composed of all eunuchs, once there was an abnormal problem in the circuit system, let these eunuchs repair and test, so as to avoid a lot of inconvenience caused by craftsmen entering the palace.

And the electrician team composed of eunuchs naturally belongs to the Ministry of Internal Servants, because are they eunuchs after all? Only belonging to the Ministry of Internal Service is the most appropriate.

After having this idea, Li An just said to Gao Lishi, and Gao Lishi immediately agreed, for this kind of trivial matter, he will not bother Li Longji, he has full power to call the shots, and he is the highest governor of the Inner Service Province, and the eunuch electrician team will be the department under his command, and it is of course a good thing that he can have multiple departments under his hands.

After all the installation work was completed, Li Ang conducted a detailed inspection of the overall situation, and asked the craftsmen to follow it carefully, and after confirming that there was no problem, he returned to the R&D center with the craftsmen and some eunuchs.

After returning to the R&D center, Ang Lee continued to engage in scientific research, and asked several craftsmen to hand over the simplest knowledge to these eunuchs, so that they could master the most basic knowledge of electricity as soon as possible, as long as they could deal with small problems.

That night, when Li Longji and Yang Yuhuan moved back to the dormitory, they were naturally very happy to see that the lighting effect of the dormitory was much better than that of the courtyard in the south, and under the guidance of the eunuch, they began to familiarize themselves with various lights and lighting effects, and finally chose a warm and romantic pink light, and enjoyed it inside.

The technology of manufacturing generator sets has gradually matured, the light bulb is very simple, as for the spotlight, it is even simpler, only need to put a bowl-shaped reflective surface in the position of the bulb, and place a convex lens in front of it, it is enough to realize the concentrated transmission of light, which can be used to make searchlights.

Since electric light is extremely important to the future development and prosperity of Chang'an City, the R&D center has carried out an emergency mobilization to speed up the construction of power generation equipment in batches, and immediately deploy it throughout the capital.

Daming Palace, Taiji Palace, and Xingqing Palace were the first to arrange power generation equipment, followed by the East Market and the West Market, then the important streets and squares in the northern half of the capital, and finally the square in the southern part of the capital.

Due to the different importance, the density of the deployment of power generation devices is different, the palace and the east and west markets are deployed more, so the density of lights is very large, and the southern square, many of them are two or three squares to arrange a generator set, and it is necessary to bear the additional burden of the street lights in the surrounding streets, so it looks relatively dark.

In addition, in the deployment of street lights, also follow the principle of more deployment in important areas and less deployment in secondary areas, the Suzaku Avenue on the central axis of the capital, and a street in the south of the imperial city, the deployment of street lights is the most, at night, the road surface can be illuminated as if it were daytime, and those small streets, the deployment of street lights is relatively less, only half of the density of the avenue, or even a quarter, as for the streets inside the square, the deployment of street lights is less, as long as you can see the road clearly, It is enough to ensure the walking of normal people.

In order to create the prosperity and luxury of Chang'an City, a lot of light bulbs are also installed on the city wall of the capital, and they are spotlights that shine on the wall, illuminating the city wall as bright as day.

At night, standing not far from the outside of the city, you will see the entire city wall very bright, and the feeling in your heart is very comfortable, especially for people from small countries from outside, who are afraid that they will be deeply shocked when they see this scene, and sincerely admire the prosperity and strength of the Tang Empire, so that they dare not covet and invade.

A power generation system, which meets the needs of the capital, is also housed in a research and development center outside the city, numerous workshops and, of course, a very important railway station, to meet the needs of these areas.

After some time, the power generation car developed by Ang Lee was also done, and soon achieved mass production, so that the train can be connected to electricity, when driving at night, each car no longer needs candles, but directly replaced by light bulbs, and the front part of the locomotive is installed with a number of high-power searchlights with strong focus, which greatly enhances the safety of night driving.

The number of electric lights installed in each carriage is of course different, and the best sleeper compartment has two bulbs installed in each small private room, and eight bulbs are installed in the aisle, so that twenty bulbs are installed in the whole carriage.

There are only ten light bulbs in the soft seat car, twelve in the hard sleeper, only six in the hard seat car, and only three light bulbs in the stable car at the rear, and it does not need to be always open.

Equipped with the most light bulbs, in fact, is the dining car, because the dining car is a place to eat and cook, you need to see more clearly, the whole dining car is equipped with more than 30 light bulbs, at night, you can illuminate the whole car as bright as day.

Due to the large number of trains and the heavy task of the R&D center, it is impossible to connect all trains to electricity in a short period of time, and it will take at least three to five months for all trains to be popularized.

In addition, a large number of steam ships have been gradually launched and assembled, and even five or six have begun to conduct sea trials, so Ang Lee must step up the manufacture of electrical systems suitable for large steam ships, so that these ships can use searchlights to observe the surrounding situation at night, in addition, with electric light bulbs, the cabin will be cleaner and brighter, which is very beneficial to improving the comfort of the crew.

Since the principles are all the same, in just a few days, the generator set suitable for the use of large steam ships was built, and mass production immediately began to meet the needs of Daxinggong steam ships.

"Ah Lang, the canned food you made last time has been stored for three months, can you open it and take a look, it is estimated that it has already stinked."

Zhao Liu walked up to Li An's side and spoke.

"Canned, don't you say it, I almost forgot, quick, take the can, let the official taste it and see if it has deteriorated."

Li Ang was very curious about whether the canned ceramic bottles he made could still be eaten after being left for three months, and if he couldn't eat them, his experiment would be a complete failure.

"Ah Lang, is this open?"

Zhao Liu brought six cans, the contents of these six cans and the location of the placement are different, and the storage time must be quite different.

"Open, all open."

Li An ordered, and with his own hands, opened a can.

"Yes, it's still fresh and you can eat it."

Li An smelled the aroma of mutton, and pinched a piece with his hand and put it in his mouth, feeling that it was still quite delicious.

"Ah Lang, it's really fresh, and the celery still tastes the same as when it was just cooked."

"Ah Lang, pork is also good, you can eat it."

Zhao Liu opened a number of cans, reached out and grabbed the food in the cans, and ate them.

"It's been three months, and it hasn't gone bad, and even the mutton in a humid and stuffy environment is fresh, which is enough to show that the canning technology is still reliable."

Li An said happily, and immediately asked Zhao Liu to set up a canning workshop, which was specially used to produce canned products.

Zhao Liu was naturally very happy, and began to arrange for the male and female servants under his command to form this project that could make a lot of money together.

For canned products, Ang Lee originally planned to use glass materials, after all, the cost of glass materials and pottery materials is not much different, and glass can see the food inside, which is much better than ceramics.

But at present, Ang Lee's manufacturing method of glass is strictly confidential, and the selling price is often dozens of times, or even more than 100 times the cost, if cans are still sold at such a high price, the price of glass bottles is already very terrible, and ordinary people can't afford it at all.

And if the price is lowered and sold at the normal price, the true cost of the medicine jade will be suspected, and in this way, the most profitable industry that Ang Lee relies on will fall, and even, many people will secretly scold Ang Lee for being black-hearted and actually selling low-cost things at hundreds of times the price.

After thinking about it again and again, Ang Lee decided to develop canned ceramics very blackly, and achieved great success, anyway, ceramic products are cheaper, and the price of the finished product can be more close to the people.

Of course, since the success of ceramic products, canned food made of glass will definitely not be a problem, and Ang Lee's canning workshop can completely make a small amount of canned food, and package it in exquisite packaging boxes, and sell it as a high-end gift.

As for the entire canned food industry, Li Ang decided to hand it over to Zhao Liu and his few wives to take care of, as well as the previous medicine and jade industry, and also handed it over to them, Zhao Liu was responsible for taking care of it outside, while Li An's wives were responsible for calculating their belongings at home and doing a good job of logistics, which could also make their lives more fulfilling and not too boring to be idle.

The canning workshop said that it would be on the horse, and it would be done in a few days, because the houses were all ready-made, and it was in the processing workshop next to the Li An Courtyard, and now it was connected to electricity, so it could work in shifts day and night.

Because the people of this era are more able to endure hardships, the demand for entertainment is relatively small, and there is no corresponding labor protection law, so as long as it is work, it is basically overtime and continues to work, and the working hours of a day are at least six hours, that is, twelve hours in later generations.

In later life, Ang Lee was a wage earner who was exploited, but at this time, he chose the exploiting class very blackly, and for his workshop, he had to implement a very inhumane two shifts, one shift during the day and one shift at night, without any rest and holidays.

In addition, for employees who take too much leave, they will be resolutely dismissed, after all, the workshop they run belongs to the nature of the enterprise, not a charity, of course, they can't recruit lazy people.
