In the early days, the indicator lights on the lighthouse were generally 400 watt metal halide lamps, because in addition to the above excellent indicators, there is also a very strong penetration power of this lamp in fog, and the range is also very long.

However, metal halide lamps also have their own disadvantages. The first is that it cannot be turned on immediately after it is extinguished, and it takes 3 to 5 minutes to recover. The second is that its power consumption is relatively large, and it will take almost half a kilowatt-hour of electricity for an hour; Third, it needs to be equipped with special ballasts, so it is relatively bulky; Fourth, compared with LED lights, the gap is relatively large, it has a low life, low light efficiency, large light attenuation, and the most important point is that it is easy to spontaneous combustion; Finally, the metal halide lamp will produce high temperatures when it is ignited, and a protective cover needs to be worn in front of the lampshade to ensure safety.

Therefore, there are 4 kinds of light sources used in the current lighthouse, and the old ones still use metal halide lamps, and the new ones or new designs use xenon lamps, induction lamps, and LED lamps.

Among them, the characteristics of the xenon lamp compared with the metal halide lamp are that it can be turned on and off at any time, and the heat emitted by itself is more than half less than that of the metal halide lamp, and it is very silent when ignited. However, its disadvantage is that it has a shorter lifespan, the brightness will be 1/8 lower than that of metal halide lamps of the same power, and it is not easy to replace the bulb at the same time.

The induction lamp, also known as the "electromagnetic induction lamp", is an international fourth-generation energy-saving and environmentally friendly new light source integrating electronics, electromagnetism, vacuum and other technologies, with the characteristics of simple structure, no electrode, no filament, high light efficiency, high color rendering and long life. However, the theoretical life of the induction lamp is 60,000 hours, and in fact, the current high-power electronic ballast technology has not made a fundamental breakthrough, and at the same time, the life of components, including the "electrolytic capacitor", is only 16,000 hours in the high-temperature environment of the induction lamp. Under the current technical conditions, the actual life of the induction lamp is less than 8000 hours, so the theoretical life can not be cited for publicity, of course, the most important thing is that its light efficiency is too low, and the maximum power can only be 185 watts, and it can not be used as several other high-efficiency light sources.

Finally, Huangshi, like others, set its sights on the light source of LED, after all, the intrinsic characteristics of LED determine that it is the most ideal light source to replace the traditional light source. It's very small and very light; Low power consumption, it consumes no more than 0 electrical energy. 1W； Long service life, under the appropriate current and voltage, the service life of LED can reach 100,000 hours; At the same time, it has high brightness and low heat, because it uses cold light technology, and the heat generation is much lower than that of ordinary lighting fixtures; Finally, it is eco-friendly and sturdy and can be recycled.

It's just that the searchlight of the lighthouse is bought, including the power cord and switches have been installed in place, but at night it is not turned on like modern society, after all, Dongluo Island is still a closed island, and other passing ships are not welcome to visit, and there is no standing and powerful naval force on the island, this island is purely fragrant Tang monk meat, I am afraid that every passing monster will be attracted by it, although Huangshi is not afraid, but it is a big trouble to deal with after all.

"Wait for my personnel to have more, and when my iron boat is bought......" Huang Shi checked the situation of these lamps and lanterns, while secretly thinking in his heart, when he returned to the shipyard yesterday, he had received a call from Ning Fan, his actions were very fast, according to the original two ways to discuss, he had found a way to give a shipyard two "ironclad ships", if the speed was fast, then a few weeks later, Huang Shi would probably be able to drive the "ironclad ship" across the ocean in the 16th century.

After checking the equipment of the watchtower, a soldier also came to report that the "Hope" was only six nautical miles away from the port, and in another hour, it would be about to arrive at the port.

Huang Shi walked over and observed through the desktop viewing glass, the "Hope" that was originally the size of a bean has become the size of an apple, and the sails on the other side of the ship are round and full, and the ship is flying towards this side.

The personnel on the ship also changed from the size of ants to the size of mung beans at this time, and in the telescope, Huang Shi saw that they were skillfully doing various operations, and those immigrants probably stayed in the cabin honestly, and did not see a single one on the deck.

Huang Shi decided to return to the group of people who had just been "abandoned" by him, and before leaving, he instructed the soldiers, "Okay, I'll go down first, you guys work hard." ”

After the soldiers saluted, they watched Chief Huang slowly disappear into the path on the mountainside.

……

The "Hope" slowly approached the dock, and the sailors put away the sails that hung high on the mast and tied them with special thick ropes, and then threw the cables from the ship to the floating dock, and lowered the iron anchors at the bow and stern.

After a few workers on the dock picked up the cables, they firmly fixed them to the positioning piles of the floating dock, and now all this is very skillful and orderly.

Now, the rope of the "Hope" has long been replaced by a modern synthetic fiber rope with tensile resistance, impact resistance, wear resistance, flexibility and softness, just like other equipment.

Synthetic fiber rope is mostly made of nylon, polypropylene, vinylon, polyester and other materials, it is compared with the steel cable, hemp or cotton rope commonly used in the past, in addition to light specific gravity, high strength, good impact resistance and wear resistance, there are also corrosion resistance, mildew resistance, insect resistance and other advantages.

What made the sailors of the "Hope" even more jaw-dropping was that the synthetic fiber cables not only exceeded the hemp and cotton ropes in strength and wear fastness several times, but also their specific gravity was smaller than that of water, so they could float on the water surface, and the operation was convenient and safe.

After Huang Shi saw the "Hope" at close range, some of his previous worries disappeared, because the "Hope" did not appear to be damaged in the slightest, and he said softly in his heart, "I am still too calm, I want to come to such a good ship and a group of experienced sailors, plus Hu Guang, a special soldier, there is really nothing to worry about." It seems that I will have to live more in the future to nourish my qi and transfer my body. ”

Huang Shi, who was relieved in this way, said to the people on both sides with a smile, "Let's go, let's go over together to greet our comrades who have returned victoriously." ”

So Huang Shi led Chen Youxin and them to the side of the boat together, and Su Er took out a notebook and prepared to wait for the ladder to be set up and then get on the ship to check, according to the regulations, he had to wear a mask to check the ship's epidemic prevention situation first, and see if there were any sick crew members or passengers, so that they could be isolated on the ship first, and then transferred after other personnel left.

Originally, Huang Shi wanted to copy the experience of other group wearers, first build a concentration camp for inspection and quarantine, and lock every new immigrant in it for a week of "purification", but unfortunately his subordinates are not those well-trained "veterans", and there is a congenital shortage of manpower, so he can only be dealt with in this way because of ugliness.

The others continued to stay by the boat, Chen Youxin was there to help guide the newcomers and maintain the order of disembarkation, and their personnel file registration and distribution of daily necessities were handled in several tents set up at the gate of the camp.

Huang Shi was also standing by the side of the ship, waiting for Hu Guang to come down and explain to him why the "Hope" would be so late for several days.

After a while, the escalator of the ship was erected, and after Su Er went up, Hu Guang, who was still wearing the Ming Dynasty shirt, walked down with a few soldiers, while the sailors continued to be busy with their work on the ship, and the immigrants could not get off the ship until Su Er finished inspecting.

When Hu Guang was still on the boat ladder, he greeted them in Huangshi below as he walked, "Hahaha, Brother Huang, good afternoon." ”

"Good afternoon." Hu Guang's greeting made Huang Shi's words just now swallow back into his stomach, and only turned into a soft sentence, "Xiaohu, everything is going well." ”

"It's all going well, everything is going well, everything is done, and no one has been lost." Hu Guang nodded.

"That's good, that's good." Hearing Hu Guang's affirmative answer, Huang Shi repeated two sentences with great relief, and then he patted Hu Guang on the shoulder and said, "Then go to my office, you can tell me about your experience this time." ”

Although Huang Shi was full of questions, he also knew that it was not very convenient to talk here, so he simply let Hu Guang go with him.

"Okay, Brother Huang." Hu Guang nodded in agreement, "Then I'll let them go back to rest first." ”

"Okay." When he said this, Huang Shi remembered that there were a few warriors behind him, and he forgot about them in his excitement just now, and it was not too late to make amends.

So he immediately turned around, with a smile, shook hands with the five soldiers on this mission one by one, and said apologetically, "Hard work, warrior, this time your mission in Fuzhou Mansion has been carried out very well, and the escort mission has also been completed......"

When the soldiers heard the chief's affirmation of themselves, their tired faces also smiled, and they saluted Huangshi one after another, and replied, "Everything is subject to the organization's arrangement." ”

Seeing them leave, Huang Shi said to Hu Guang, "They will also be the loveliest group of people in the future." ”

"Hmm." Hu Guang nodded heavily, this is also what he hopes to do the most after coming to this era, and it is also one of his ideals, those who want to be the king and dominate, want to have three wives and four concubines, and live an extremely corrupt life that cannot be lived in this world, is not the life he wants. He wanted to work with Huangshi to relieve the people from hanging upside down, use modern civilization to conquer ancient barbarism, and thus rewrite the history of the Chinese nation and the world.
