Ji Han is responsible for drilling the cabinet, Cao Wei and Cheng Youping are responsible for the main circuit series connection and electrical component assembly of the light source equipment, and Yu Hua is responsible for welding the cabinet and final assembly. The four people have a clear division of labor and work together in an orderly manner.
After the cabinet holes were drilled as required and the measurements met the tolerance standards, Yu Hua immediately began to assemble the equipment parts, installing the circuit boards and main equipment in an orderly manner, routing them, and finally integrating and packaging them.
Soon, twenty minutes later, under the watchful eyes of three people, the first official version of the portable lighting source was assembled in Yu Hua's hands.
The entire light source equipment is boxy. There are two meters on the front, one displays the input voltage and input current, and the other displays the output voltage and output current. It is simple to use, just turn to the working mode and press the switch.
The light bulb is separated from the device and supports 100-watt light bulbs to 60-watt light bulbs.
As for charging, just connect it to an external power source.
"Lao Yu, please turn on the power and try it out." Looking at the brand-new lighting source, everyone seemed extremely excited. Ji Han, whose face was covered with dust and sweat, was the first to shout.
Feeling the gazes and emotions of the three people, Yu Hua smiled, nodded slightly, turned the mode button with his right hand, and then pressed the switch.
"Click!" A crisp switch sound came out.
The next second, the 100W incandescent lamp installed at the lighting source output port was suddenly powered on and activated, releasing a dazzling light.
"Hahaha, we succeeded." Ji Han looked at the light coming from the lighting source, with a hint of excitement in his eyes, and couldn't help laughing.
Compared with the original extremely simple lighting power supply, this official version of the lighting source, which has significantly improved its technological content by two steps, has far-reaching significance.
This is the first time Jihan has produced such advanced lighting equipment.
"This is the first lighting source we have made. Let's give it a name, so as not to keep calling it a portable lighting source, which has a weird name." Looking at the lighting source that emits dazzling light, a smile appeared on Yu Hua's face, and his eyes
He turned to the other three people and said.
"How about calling it the Qiming Lamp? It reveals light and illuminates the future." Cao Wei nodded after hearing Yu Hua's words.
Cheng Youping expressed a different opinion at this time: "This name is okay, but I want to call it Guangming Lamp. It blooms in the darkness, gives us light, and illuminates the direction of the future."
"I want to call it the Lantern of Hope. It is our hope for a great future, and it is also a hope that symbolizes the rise of China." Ji Han said.
"..." Yu Hua saw three roommates who had different opinions and felt that something was wrong.
"I think Qiming sounds good, Guangming is too straightforward, and Hope is too sensational." Cao Wei retorted.
Cheng Youping responded: "What's wrong with straightforwardness? It is a trend for vernacular Chinese to replace classical Chinese, and it is also a trend for simplified Chinese characters to replace traditional Chinese characters. I think Guangming sounds good."
"What is sensationalism? I am empathizing, okay? Qi Ming is a literary scholar. We are not students in literature classes, so we hope the lights sound the best." Ji Han said immediately.
"What is a trend? I don't understand. Although simplified Chinese characters are easy to use, they don't have the charm of traditional Chinese characters, and classical Chinese characters are even more profound."
"The trend is the change of the times..."
"Wouldn't it be better to let the name of hope spread throughout No. 4 Middle School, throughout Xicheng, throughout Peiping, and even throughout China?"
"No, Qiming is the best!"
"you……"
The three people kept arguing and fighting over the name of the lighting source.
"Uh... I say, if you continue to argue like this, when will the eight lamps be finished?" Yu Hua watched as the quarrel between the three gradually became more intense, and quickly offered words of advice.
After hearing Yu Hua's voice, the three people who kept arguing finally gave up.
Ji Han, who was out of breath, turned to Yu Hua and said, "Lao Yu, it was you who opened this head. What name would you like to use?"
Yu Hua wanted to say that you are the main material merchant and supplier, so it’s up to you to choose. He looked at the eyes of Cao Wei and Cheng Youping, and the corners of his mouth twitched slightly: "I think it's all good. Since everyone is arguing, then let's
How about we put it on hold for now and wait until Zhou Yuan and Lao Liu come back to decide?"
Qiming?
bright?
hope?
Just a crappy lighting source, does it need such a cool name?
Yu Hua didn't understand, but he didn't dare to say anything.
"good."
The three of them looked at each other, nodded and said.
The dispute over the name of the light source was put aside for the time being, and the three became good brothers again. Yu Hua began to weld the second cabinet. With the experience of the first welding, the second welding speed was significantly faster. It only took less than ten minutes.
Two cabinets are ready.
At the same time, the three of them were busy working on their own. According to Yu Hua's prior arrangements, they divided the work and cooperated in an orderly manner. The two workers responsible for guarding were helping out and doing some chores.
Time passed slowly, and in the evening, the eight lighting sources were finally completed. After general electrical inspection, there were no problems and the quality was excellent.
After a busy afternoon, Yu Hua and the three of them all gained valuable practical experience. After the quality inspection, they didn't have time to eat, so they immediately found two small carts and packed them one by one.
After the eight lighting sources were loaded into the truck, the four of them set off together, leaving the temporary workshop and transporting them to the school. The two workers who did odd jobs were still responsible for guarding them.
As the night fell, the cold wind was as sharp as a knife, making my cheeks hurt.
If the winter in the south is a magical weapon, no matter how thick you wear it, you will shiver with cold, then the winter in the north is a physical weapon, it is so cold that it can freeze people to death.
After entering the school, the four of them were divided into two groups. Yu Hua and Ji Han went straight to the girls' dormitory, while Cao Wei and Cheng Youping went to the boys' dormitory.
…
Not long after, Yu Hua and the two pushed the trolley to the girls' dormitory and stood at the door of the dormitory.
Stopping, Yu Hua stepped forward, found the dormitory aunt in charge of the girls' dormitory, and informed Fang Yu in Room 1A and 2.
Seeing Yu Hua and Ji Han behind him, the dormitory aunt looked a little strange, but she didn't say anything, so she asked the two to stay at the door, then turned and headed to Room 1A and 2.
After waiting for about three minutes, Fang Yu, wrapped in a women's coat, hurried downstairs and faced the biting cold wind to the door of the bedroom.
"Yu Hua, why are you here? What's the matter?" Fang Yu stopped, panted a little, exhaled a breath of white mist, her cheeks were slightly red, and her eyes fell on Yu Hua.
"The three lighting sources you ordered have been brought to you." Yu Hua was a little surprised when he heard this and responded.
Only then did Fang Yu react. He glanced at Ji Han and the trolley with four lighting sources standing behind him, with a hint of embarrassment on his face: "Oh, I'm sorry, I've been too busy these days.
