Chapter 77: The Lighting Lamp?
Ji Han is responsible for the drilling of the cabinet, Cao Wei and Cheng Youping are responsible for the main circuit series connection and electrical device assembly of the light source equipment, and Yu Hua is responsible for the welding of the cabinet and final assembly.

After the drilling of the cabinet was drilled as required and the measurements met the tolerance standard, Yu Hua immediately began to assemble the equipment parts, install the circuit board and main equipment in an orderly manner, route the wires, and finally integrate and package.

Soon, after 10 minutes, under the watchful eyes of the three, the first official version of the portable lighting source was assembled in Yu Hua's hands.

The whole light source device is square, with 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 easy to use, just turn it to the working mode and press the switch.

The bulb is separate from the device and supports 100 watt bulbs - 60 watt bulbs.

As for charging, it can be connected to an external power supply.

"Lao Yu, quickly turn on the power and try it." Looking at the newly released lighting source, everyone seemed extremely excited, and Ji Han, whose face was covered in dust and sweat, shouted first.

Feeling the gazes and emotions of the three, Yu Hua smiled, nodded lightly, turned the mode button with his right hand, and then pressed the switch.

"Da!" A crisp switch sound came out.

In the next second, the 100W incandescent lamp installed at the output port of the lighting source was suddenly powered on and activated, releasing a dazzling light.

"Hahaha, we succeeded." Ji Han looked at the light from the light source, a hint of excitement appeared in his eyes, and he couldn't help laughing.

Compared with the original very simple lighting power supply, this official version of the lighting source with two levels of technological content is significantly more meaningful.

This is the first time that Ji Han has produced such advanced lighting equipment.

"This is the first lighting source we have made. Let's name it, so as not to keep calling it a portable lighting source, the name is weird." Looking at the lighting source that emits dazzling light, a smile appeared on Yu Hua's face, and his eyes Throwing at the other three, said.

"How about it called Qiming Deng? Enlighten the light and illuminate the future." Cao Wei nodded when he heard Yu Hua's words.

Cheng Youping expressed a different opinion at this time: "The name is fine, but I want to call it the bright light. It blooms in the dark, gives us light, and illuminates the future direction."

"I want to call it the Hope Lamp. This is the hope of each of us heading towards a great future, and it also symbolizes the hope of the rise of China." Ji Han said.

"..." Yu Hua saw three roommates with different opinions and felt that something was wrong.

"I think Qiming sounds good, but Guangming is too straightforward, and hope is too sensational." Cao Wei retorted.

Cheng Youping responded: "What's wrong with the straightforwardness? It is a trend for vernacular to replace classical Chinese, and it is also a trend to replace traditional Chinese with simplified characters. I think it is bright and pleasant."

"What is sensational, I'm empathizing, okay?! Qiming Wen is a crepe, and I'm not a literature student. I hope the lights are the best." Ji Han said immediately.

"What is the trend? I don't understand. Although simplified characters are easy to use, they don't have the charm of my traditional Chinese characters. The classical Chinese characters are more extensive and profound."

"The trend is the change of the times..."

"Could it be that the name of Hope spreads throughout No. [-] Middle School, Xicheng, Peiping, and even China, isn't it?"

"No, Qiming is the best!"

"you……"

The three were constantly arguing, fighting over the name of the lighting source.

"Uh... I said, if you keep arguing like this, when will the eight light sources be finished?" Yu Hua watched the quarrel between the three gradually intensify, and quickly spoke out to persuade them.

Hearing Yu Hua's voice, the three people who were constantly arguing gave up.

Panting, Ji Han turned his eyes to Yu Hua: "Old Yu, you drove this head, what name do you want to use?"

Yu Hua wanted to say, you are the main material supplier and supplier, so you can choose. Looking at the eyes of Cao Wei and Cheng Youping, the corners of his mouth twitched slightly: "I think it's fine, since everyone is arguing endlessly, then Put it on hold for now and decide when Zhou Yuan and Lao Liu come back, how about that?"

Qiming?

bright?

hope?

Just a broken light source, do you need such an awesome name?
Yu Hua didn't understand, but he didn't dare to say a word.

"it is good."

The three looked at each other and nodded.

The dispute over the name of the light source was temporarily put on hold, and the three of them became good brothers again. Yu Hua started to weld the second cabinet. With the experience of the first welding, the welding speed of the second was significantly faster, and it only took less than 10 minutes. Two cabinets are ready.

At the same time, the three of them were busy, and according to Yu Hua's prior arrangements, they divided their work and cooperated in an orderly manner.

Time passed slowly, and in the evening, the eight lighting sources were finally completed. After a general routine electrical inspection, there was no problem and the quality was excellent.

After a busy afternoon, Yu Hua and the three of them all gained valuable practical operation experience. After the quality inspection, it was too late to eat, so they immediately found two small carts and packed them in turn.

After the eight lighting sources were loaded, the four of them set off together, left the temporary workshop, and transported them to the school. The two chores workers were still in charge of guarding duties.

The night fell, and the cold winds were as sharp as knives, blowing on the cheeks.

If the winter in the south is a magical weapon, no matter how thick you wear it, you will shiver from the cold, then the winter in the north is a physical weapon, the serious cold that can freeze people to death.

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, the two of Yu Hua pushed the cart and arrived at the girls' dormitory, standing at the door of the dormitory.

Stopping, Yu Hua stepped forward, found the dorm aunt in charge of the girls' dormitory, and informed Fang Yu in Room [-], A, and Room [-].

Seeing Yu Hua and Ji Han behind her, the dormitory's aunt looked a little weird, but she didn't say anything, so the two stayed at the door and turned to room [-], A and [-].

After waiting for about 3 minutes, Fang Yu, who was wrapped in a women's overcoat, hurried downstairs, facing the bitter cold wind, and came to the door of the dormitory.

"Yu Hua, why are you here, what's the matter?" Fang Yu stopped, gasping for breath, exhaling a white mist, her cheeks flushed, 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.

Fang Yu just realized that, looking at Ji Han standing behind him and the trolley carrying four lights, a look of embarrassment appeared on his face: "Oh, I'm sorry, I've been too busy these days. Forget it, help me move in."
