Shorten the gap with the world LED artisans continue to "Tiangong Kaiwu"

According to the "News Morning News" report, there is no trace of any common lamps in the room, only a luminous ceiling, and different light sources such as starry sky, moon night, and daylight can be changed according to needs. In the moonlight state, a "full moon" hangs on the ceiling, waving a cold "moonlight" into the room; in the daylight state, the "full moon" will turn into a "sun", reflecting the interior like daylight. This is not a description in a mythical story, but a scene described by scientists in semiconductor lighting.

LED is a semiconductor that can convert electrical energy into light energy. It not only has high light efficiency, but also has a service life 50 times that of ordinary incandescent lamps and 12.5 times that of spiral energy-saving lamps. Mobile phones, computers, digital cameras, and city landscape lights all have semiconductor lighting. In Shanghai, there are such a group of technologists who are actively participating in the "third lighting revolution" in human history.

Entering the production workshop of Yingrui Optoelectronics Technology (Shanghai) Co., Ltd., as if entering a science fiction movie. The one-piece blue overalls, masks, gloves, and special shoes with leggings are "fully armed" to reveal only two eyes; after the dressing is completed, you must also "blow" in an isolation door to ensure "precious" LED chips are not affected by dust and static electricity.

In the workshop, a few blue "spacemen" are discussing what is around a display. 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 metal is worth 2.2 million US dollars."

In 2011, Yingrui Optoelectronics' first batch of MOCVD machines entered the factory as planned. In early 2012, the Yingrui Optoelectronics team successfully developed HV-LED, becoming one of the few high-tech enterprises in the world capable of manufacturing HV-LED. Mass production was achieved in the first half of 2012, and orders were in short supply.

The core technical team and management team of Yingrui Optoelectronics have created a miracle in the development of the semiconductor industry in mainland China. In just a few years, the gap between the technical level of semiconductor manufacturing in mainland China and the mainstream advanced level in the world has been shortened by 20 years. . At present, Yingrui's products have been widely used in TV backlight, traffic lighting, automobile lighting, landscape lighting and other fields. And it is expected to reach a production capacity of 100 sets of MOCVD within three years and become the largest and most advanced LED chip development enterprise in China.

The coal-based energy structure puts China's total carbon dioxide emissions at the forefront of the world, and the development of LED technology is one of the breakthrough points towards a low-carbon economy.

In recent years, the global LED lighting market has a size of approximately US $ 100 billion, and the market size of LED-based display devices has been approximately US $ 40-50 billion. As a gathering place for high-end manufacturing, Shanghai Lingang Industrial Park cannot naturally "forget" the LED industry, and Yingrui Optoelectronics has also become a "trump card" for Lingang. In addition to this "ace card", there are several "good cards" in Lingang's hands. Lingang Group is actively introducing leading companies in the LED field and creating a national LED high-end energy-saving lighting industrial base.

"Nuclear Boat" once praised the superb micro-carving skills of the "capable craftsmen" in Jiangsu and Zhejiang in the Ming Dynasty. Today, in Lingang New City, those "Jiangnan clever hands" not only inherited the bold and meticulous craftsmanship of their ancestors, but also combined modern management and sophisticated technology to write a new one on the size of a baby's palm-sized LED chip. "Tiangong Kaiwu" of the times.
