Hangzhou scenery and complementary LED street lights dance everywhere



Scenery complementary lights? It sounds like a feng shui artifact. In fact, it is a new type of environmentally friendly street light. Two days ago, a photo of Xinhua News Agency of “Shancheng Yuncheng Low Carbon Street Light” was circulated on the Internet. The more than 300 lamps were all LEDs. There was a small fan on top and a solar panel below. Although it looks good, it can rely on wind energy and solar energy to generate electricity.
After inquiring about it, the author found that the company that produced more than 300 “wind and light complementary LED street lights” was in Hangzhou. They have recently sold “windlights” to Hainan Sanya, Anji Tianhuangping, Shanghai Pudong International Airport Airport Industrial Park, and Inner Mongolia Jining City. Their assistant general manager told the author that the lights were not only installed in many places in China, but also sold to places such as South America and Chile.
Around 2005, the company turned from developing power automation products to the LED lighting industry, aiming at the country's energy-saving needs. In the process of development, the startup team came up with the "solar + wind energy" LED street light mode. Because of the rainy weather in the south of the Yangtze River, solar-type municipal lamps often appear unstable.
This idea was brewed and prepared for a long time. Until the price of semiconductor materials fell last year, it was officially implemented. It was welcomed by local governments that are catching the “energy-saving demonstration project” – although the initial installation cost of each lamp needs more than 20,000, it does not need to be laid. Cables, power saving, long life and many other advantages, as well as a new LED concept, offset the cost disadvantage.
The technology content of this street lamp is not only integrated with various energy sources, but also the wind power, photoelectric and Battery Capacity, and street lamp power according to different lighting and climatic conditions in each place.
“For example, the Ningbo Economic Development Zone is located in the Beilun area, and the wind power is strong. The configuration is: 400 watt wind turbine, 160 watt solar panel, 400 amp capacity battery, 90 watt street lamp; and Shanghai Pudong Airport airport The configuration of the industrial park, the power of the solar panel should be mentioned 200 watts, the power of the street lamp is reduced to 60 watts, and the battery has two, each 150 amps capacity." Xiehe Optoelectronics General Wu Jian told the author.
Of course, the “wind-and-complementary” street light is just one of many products of Xiehe Optoelectronics. In Wu Jian’s view, “the LED market is too big.”
In recent years, he has found more and more competitors around him - Guanghang City specializes in the semiconductor lighting industry (mainly including light-emitting diodes (LED) and organic light-emitting diodes (OLED)), there are more than 60 companies, and 200 Yujia supporting enterprises. Hangzhou already has Zhejiang University's three-color instruments, Zhongwei Optoelectronics, Zhongzhou Optoelectronics and other well-known semiconductor lighting companies in the industry, as well as Silan Microelectronics already listed...
But the output value of so many companies (according to a rough estimate of more than 1 billion), compared with the capacity of the lighting market is only a small amount.
"Take a street lamp and say that in 2009, the Ministry of Science and Technology launched the 'Ten Cities and Ten Thousand' semiconductor lighting application engineering pilot project, there are about 15 billion yuan of business opportunities - that is only the amount of pilots in 21 cities." Wu Jian told the author.
“There are about 28 million street lamps in China's road lighting market. The number of street lamps added and replaced every year is about 3 million to 4 million. If these traditional street lamps can be replaced by LED lights, it will be a huge market. In addition to municipal road lighting. There are also many applications such as electrical indicator lights, display screens, landscape lighting, interior decoration, etc."
