Photovoltaic industry needs to pay attention to outdoor lighting to solve the battery

Since the commercialization attempt began at the beginning of this century, the photovoltaic LED lighting industry has experienced nearly a decade of development, and has become a high-tech and high-growth industry that uses technology as a guide and application solutions as a means.

On June 29th, “LED-People-Viewpoint-Lighting Application-Academic Exchange-The First China Special Conference on Photovoltaic and LED Lighting Applications” was held in the Great Hall of the People in Beijing Golden Hall. It is reported that this forum was organized by the Aladdin Lighting Network, the Varsity Lighting, Ding Shenghua and other contractors, and the organizer Shenzhen Hao Wei Photovoltaic Lighting Co., Ltd. jointly carried out. The guests invited by this conference were all important institutions and scholars in the industry. For the first time, they all expressed their opinions on the theme of “China Photovoltaic LED Lighting Application”.

Photovoltaic lighting is the result of a combination of science and technology, policy, and market Ding Kongxian, a professor at the Physics Department of Wuhan University, was the first guest to give a keynote speech, bringing with him a wonderful speech titled "Development and Analysis of Photovoltaic Lighting." He said that the rise of photovoltaic lighting industry in China is the result of a combination of technology, policy and market.

According to reports, at the beginning of the development of the photovoltaic lighting industry, almost no LED was available in the country, and even yellow ones could not be purchased. The LED display with lighting function was available in the market, but LED lighting did not. Since solar cells are an expensive semiconductor industry, coupled with the large power consumption of lighting fixtures at that time, the combined products of the two are used only under extreme circumstances, so that the industry has not been developed, so photovoltaic lighting was introduced twenty years ago. Only the product has no industry. For the first time in the mid-1990s, there were yellow LED lighting fixtures with similar incandescent light spectrum. Surprisingly, the product was very popular in the market. In the semiconductor industry such as LED and solar cell processing, which is not widely popular due to its high cost, Chinese companies began to seek "breakthroughs."

“In addition, the Ministry of Science and Technology has paid close attention to this industry very early and established a topic during the '15' breakthrough in 2004. At that time, our company and Shenzhen University took this project. In order to show a street light, electricity is not needed. Its light does not require incandescent light," said Ding Kongxian. “Now this kind of street light is commonplace. Chinese companies have made breakthroughs in meeting this demand in the market. It can be said that China's photovoltaic industry has illuminated the world. ."

Solving the Battery Problem Focusing on the Development of Outdoor Lighting Ding Kongxian predicted that LED lighting will have a breakthrough in the last two to three years. “The advantages of LED lighting, whether it is light efficiency, energy saving and environmental protection, have been highlighted, and are defined as “third generation light sources”, and have entered our daily lives in particular for the past two years. Photovoltaic lighting, first of all, is power generation, and the second is lighting. The third is the control system, and the fourth is the power generation system. Chinese companies can use ordinary solar cells or even scrap to produce high-efficiency products.” Ding Kongxian said, “Everyone says that solar energy, LED, and photovoltaic are the advantages of combining, a bit like With '.'

However, he also proposed that only one thing needs to be solved in the photovoltaic lighting industry, that is, the battery problem. “One thing that photovoltaic lighting industry needs to break through is the battery. Now, the time limit for solar battery use can be guaranteed for 25 years, and the LED is for tens of thousands of hours. Let us imagine if our battery can be limited to 10 years or so. What is the situation?” Ding Kongxian said that photovoltaic lighting is a complete green industry for energy conservation and environmental protection. New energy vehicles in this industry will be equipped with batteries to a large extent. If the storage battery is solved, photovoltaic lighting will have a wide market, and there should be hundreds of billions of yuan in China alone. The RMB market.

In addition, he also mentioned in his speech that, whether it is at home or abroad 20 or 30 years ago, outdoor is very dark and there is no light at all. Nowadays, outdoor lighting accounts for 30% of all lighting, and most of outdoor lighting can use solar energy. Power generation provides energy. “So I hope that experts present here will pay attention to outdoor lighting design. This is a big market and there will be great development in the revitalization of the national industry.”
