Working hard for years to create billion LED lighting company

"Entrepreneurship is to look for a way to persist!" Yesterday, at the Kaifu District Business Youth Forum and the micro-credit through train, Liang Jun, the general manager of Hunan New Yasheng Technology Development Co., Ltd., shared the entrepreneurial success with entrepreneurial youth. Mystery." More than 10 years ago, Liang Jun started as a lamp apprentice worker. Today, his LED (semiconductor device) display company has entered Germany, Indonesia, Singapore and Vietnam, and its fixed assets have reached 100 million yuan.

“Before the 70s” Liang Jun’s hometown was in the countryside of Huanghua Town in Changsha County. Because of his family’s difficulties, he was able to drop out of school as soon as he started. In 1991, a relative introduced him to an LED lamp factory as an apprentice. In 5 years, Liang Jun stepped from the apprentice to the workshop director and sales manager.

“In 1997, I partnered with the company to open the LED lighting company and “discussed” with the partners. In 2001, Liang Jun joined 60,000 yuan to open a home-style workshop in Kaifu District. Unexpectedly, the first business suffered a setback. "At that time, the business of a sports scoreboard in Chengdu, Sichuan Province, was slightly overdue, and the other party had 80,000 yuan not paid." Liang Jun still remembered.

Since 2004, Liang Jun has gradually emerged from the predicament and turned his sights to international exhibitions such as Shanghai, Germany, and Dubai, and frequently harvested international orders. This year, Liang Jun also won an LED display contract for part of the 2014 World Cup in Brazil. At present, Liang Jun’s new Yasheng has also expanded from a small workshop rented to become an LED optoelectronic industrial base covering an area of ​​30,000 square meters, sold to more than 60 countries and regions in the world, and established branch offices in many countries. Become the leader of the "photoelectric Xiang Army."

It is reported that this activity was carried out jointly by the Communist Youth League Kaifu District Committee, the Kaifu District Venture Office, and the Jinxia Economic Development Zone Administrative Committee to integrate their respective entrepreneurial service resources and build an exchange and cooperation platform for entrepreneurial young people in the district.

Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
