In 1962, General Electric's Nick Holonyak Jr. developed the first practical use of visible light-emitting diodes, when the color of the light was red.
In 1996, Japan Nichia Chemical Industry Co., Ltd. introduced white LEDs. In 1999, the luminous efficiency reached 15lm/w.
In 2000, the United States launched the holy grail light effect has reached 40lm / w.
By 2008, after more than 40 years of development, LEDs are now well known. Red, orange, yellow, green, blue and other color light technologies are mature. The brightness of white LEDs has been increased from the initial 15lm/w to 190lm/w experimental data. High-brightness LEDs have been used in mobile phones, displays, automobiles, traffic signals, Mature applications such as landscape decoration and special work lighting have been achieved.
China has also experienced the emergence and development of the LED industry. Intuitively, from the beginning of the LED lighting lights in the building beams to the increasingly widespread LED street lights, from the rough outdoor advertising display screen to the present With the increasingly refined LED super large screen, the technology of China's LED R&D and application has been improved by leaps and bounds. As the earliest LED application, Guangdong Yayi Semiconductor Application Technology Co., Ltd. has been in the typical development stage of LED from the beginning to the broader stage since its establishment in 2000. Guangdong Yayi Semiconductor has a more personal experience for the development and growth of LED in China. .
Aladdin Lighting Network exclusive interview with Wu Wenfeng, the chairman of Guangdong Yayi Semiconductor Application Technology Co., Ltd., the first article for Aladdin lighting network users to present the overall sketch of Guangdong Yayi.

Start: Guangdong Yayi Semiconductor is the veteran of China's LED application industry. As a new industry, semiconductors have attracted the attention of the state. In 2003, the National Semiconductor Coordination Leading Group was established. By 2004, the Ministry of Science and Technology had set up the National Semiconductor Lighting Engineering R&D and Industry Alliance. At that time, only a few dozen companies in the country focused on the LED lighting industry. Home, Guangdong Yayi Semiconductor Application Technology Co., Ltd. has proposed the concept of LED lighting since 2001 and became the first member of the National Semiconductor Lighting Engineering R&D and Industry Alliance.
When talking about how to have a long-term vision to select the LED lighting industry as the main direction of the company, Chairman Wu said that Guangdong Yayi Semiconductor Application Technology Co., Ltd. is a manufacturer of LED packaging and has extensive experience in LED device production. Market experience. With the improvement of LED light efficiency and price, LED will become an illumination source, and the inherent characteristics of LED light source will become a mainstream trend as an illumination source.
Development: Guangdong Yayi Semiconductor LED is used in landscape lighting. In 2003, the luminous efficiency of LEDs was not high, but it has been applied to landscape decoration and lighting. Guangdong Yayi Semiconductor has resolutely shifted its focus from LED packaging to LED lighting applications, putting its main energy and R&D power into LEDs. Landscape lighting field. Firstly, the LED landscape decorative lighting series lamps were first introduced in China, and large-scale LED landscape lighting engineering applications were carried out in Shanghai Nanjing Road, Guangzhou Tianhe District, Guangzhou Pearl River and other banks. When other manufacturers competed in the spirit of Chinese urban landscape lighting and lighting projects. The landscape lighting project of Guangdong Yayi Semiconductor has been paved all over China's major cities, and has completed the construction of nearly 100 major projects, and extended to the first ancestors of LED landscape lighting applications in Hong Kong, Macao and Guangdong. step.
Metamorphosis: Guangdong Yayi Semiconductor has been transferred to the development of indoor lighting equipment with market demand. Snakes have suede and tend to grow and grow after painful stripping and metamorphosis. The transformation of Guangdong Yayi Semiconductor has never stopped. In the LED city lighting and architectural lighting applications are booming in the industry, in 2006, Guangdong Yayi Semiconductor once again decided to further extend the lighting products. Due to the further improvement of LED light efficiency and reliability, future lighting applications will shift to indoor space lighting. Based on the judgment of LED future market, Guangdong Yayi Semiconductor decided to seek more distinct advantages and professional competitiveness, focusing on R&D and production. In 2008, LED lighting fixtures for white burners and fluorescent lamps were introduced, and in 2008, high-quality LED fluorescent lamps, backlight ceiling lamps and LED downlights were introduced to the market.
However, the opportunities in the market are everywhere. At that time, the country formulated a plan to eliminate incandescent lamps. In the next five years, CCFL (Cold Cathode Fluorescent Lamps) will also seek new and more energy-saving and environmentally friendly light source replacement. Guangdong Yayi quickly seized this opportunity and decided to adapt to the world trend to cut into this field, and then clear the new positioning of TV-LED backlight module and small backlight of home appliances.
