According to the "News Morning News", there is no trace of the current common lamps in the room. There is only one ceiling that will glow, and different light sources such as starry sky, moonlight, and daylight will be changed as needed. In the moonlight state, a full moon hangs on the ceiling, swaying the cold moonlight into the room; in the daylight state, the full moon turns into the sun, reflecting the interior as white. This is not a description in a mythological story, but a scene in which scientists describe semiconductor lighting.
LED is a semiconductor that converts electrical energy into light energy. It not only has high luminous efficiency, but also has a service life of 50 times that of ordinary incandescent lamps and 12.5 times that of spiral energy-saving lamps. Mobile phones, computers, digital cameras, and urban landscape lights all have semiconductor lighting. In Shanghai, there are such a group of scientific and technological people who are actively participating in the third lighting revolution in human history.
Into the production workshop of Yingrui Optoelectronics Technology (Shanghai) Co., Ltd., as if entering a science fiction movie. One-piece blue overalls, masks, gloves, and special shoes with leggings are fully armed to reveal only two eyes. After the dressing is completed, it must be blown in an isolation door to ensure that the delicate LED chips are protected from dust. The effect of static electricity.
In the workshop, several blue astronauts are discussing around a monitor. The staff told reporters that this is the company's most advanced MOCVD machine. It is one of the core devices used to make LED epitaxial wafers. This machine, bare bare metal, is worth $2.2 million.
In 2011, the first batch of MOCVD machines from Yingrui Optoelectronics entered the factory as planned. At the beginning of 2012, Yingrui Optoelectronics team successfully developed HV-LED, becoming one of the few high-tech companies in the world that can manufacture HV-LED. In the first half of 2012, mass production was realized, and orders were in short supply.
The core technical team and management team of Yingrui Optoelectronics have created a miracle in the development of China's semiconductor industry. In a short period of time, the gap between the technical level of semiconductor manufacturing in China and the world's mainstream advanced level has been shortened by 20 years. . At present, Yingrui Optoelectronics' products have been widely used in TV backlighting, traffic lighting, automotive lighting, landscape lighting and other fields. It is expected to reach 100 MOCVD scale production capacity within three years and become the largest and most advanced LED chip development enterprise in China.
The coal-based energy structure makes China's total carbon dioxide emissions at the forefront of the world, and the development of LED technology is one of the breakthrough points toward a low-carbon economy.
In recent years, the global LED lighting market has a scale of about 100 billion US dollars, and the display device market with LED as a light source is about 400 billion US dollars. As a gathering place for high-end manufacturing, Shanghai Lingang Industrial Park naturally cannot forget the LED industry. Yingrui Optoelectronics has also become a trump card in Lingang. In addition to this trump card, there are several good cards in the hands of Lingang. Lingang Group is actively introducing leading enterprises in the LED field and creating a national-level LED high-end energy-saving lighting industry base.
"Nuclear Zhou Ji" once praised the skillful craftsmanship of the Ming Dynasty in Jiangsu and Zhejiang provinces. Today, in Lingang New City, those Jiangnan skillful people not only inherit the daring craftsmanship of the ancestors, but also combine modern management and high-tech technology to write a new era on the LED chips of one baby's palm. Heavenly work.
After using our car for a long time, the interior will become dirty, with oil stains, stains, and other things that need to be cleaned.
Car washing refers to the cleaning of car appearance, which is a problem that every car owner or driver often faces. In recent years, car washing shops have gradually become a hot investment project in many large and medium-sized cities.
The steps and operation methods of car cleaning are important precautions for car cleaning. A good car cleaning can have a good maintenance effect on the car.
Car cleaning is the process of removing dirt, dust, grime, and other contaminants from a vehicle's exterior and interior surfaces. This includes washing the exterior, cleaning the wheels and tires, vacuuming the interior, wiping down the dashboard and other surfaces, and cleaning the windows. Car cleaning can be done by hand or with the use of specialized equipment and products, such as pressure washers, steam cleaners, and detailing brushes. Regular car cleaning helps to maintain the appearance of the vehicle, protect the paint and other surfaces, and prevent corrosion and other damage.
