Sunda leads the domestic LED street lamp industry with independent innovation
——Interview with Mr. Zhang Hongyou, R&D Engineer of Sangda
Editor's note: At the beginning of this year, the country officially launched the “Ten Cities and Ten Thousand Miles†project. The Chinese semiconductor lighting industry has also begun to enter the fast lane of development. Faced with a huge market, the relevant manufacturers collectively strive for it, and the challenges faced in the development process are We are confused. Can the products of Chinese national enterprises shoulder the heavy responsibility of “Ten Cities and Ten Thousand Citiesâ€? Is the government's large-scale advancement suspected of having a seedling? How to solve the problem of insufficient innovation in domestic enterprises? In this regard, Gaogong LED Network produced the topic of “China's LED Industry under the Ten Cities and Lightsâ€, describing the impact of “Ten Cities and Ten Thousand Cities†on China's LED industry from various aspects such as technology, market and coping strategies. At the same time, we also interviewed a number of industry experts to listen to their understanding of the industry. The following is an interview with Sanda.
In February 2009, the Shenzhen Municipal Government selected 29 companies to conduct LED street lamp testing. Shenzhen Sunda Industrial Co., Ltd. was listed among them. Gaogong LED Network sent a reporter to interview the company. Mr. Zhang Hongyou, the company's research and development engineer, received us.
It is understood that Shenzhen Sunda Industrial Co., Ltd. was established in 1993 and is currently listed on the Shenzhen Stock Exchange. The company's business involves multiple areas, including electronic products, emerging electronic components, real estate, commerce and so on. The company's LED lighting covers a wide range of LED street lights, tunnel lights, indoor lighting, solar LED lights and so on.
LED street light performance leading domestically
Last year, the Shenzhen Science and Technology and Information Bureau released the “Second Batch of Publicity Lists for Shenzhen Independent Innovation Product Certification in 2008â€, which is famous on the LED Street Lights. In June of the same year, the company's first high-power LED street lighting model project was completed in the Science and Technology Middle Road of Shenzhen High-tech Park.

Zhang Gong said that Sunda Power Division has 20 years of technical experience and produces tens of millions of DC power supplies every year. These self-developed LED power supplies ensure that they are synchronized with the life of the lamps. The LED light sources used by them are the latest LED modules of the well-known LED company Osram.
He said that Sanda adopts the patented heat-dissipation technology independently developed by the company. This heat-dissipation method uses heat-dissipating aluminum alloy materials and multi-stage heat dissipation to ensure uninterrupted normal operation at a maximum temperature of 55 degrees. The heat dissipation structure utilizes nature most efficiently. Convection heat dissipation, while preventing dust accumulation. Combining the advantages of all aspects, their node temperature can be 60 degrees and the life expectancy is more than 50,000 hours.
Sunda's LED street light
LED lighting started in 2005. It has successfully piloted 7 and 8 roads in Shenzhen.
At present, the LED street lamp market in Shenzhen has just started. It is in the pilot stage. We have successfully piloted 7 or 8 roads in Shenzhen. Zhanggong excitedly told us. He said that the real start of LED lighting began in the second half of 2007, and many important research and development achievements have appeared one after another. The lumen efficiency and life expectancy have been greatly improved, and gradually entered the popularization stage. Previously, it was mainly used in small power applications such as traffic lights. . He pointed out that Sunda has been doing LED lighting since 2005 and has been in the market for four years since it entered the market. (Text / high-tech LED network Zeng Cong)
