According to the Reuters natural light into underground garage, as long as days without dark, you can not consume electricity; with smart photovoltaic panels, but also light up in low light conditions. Where does this “black technology†come from? This light-guide lighting system saved more than 100,000 yuan in electricity bills for an underground parking lot last year. Its founder, Peng Pinjia, became a “porter of natural lightâ€.
Entrepreneurship spends a year researching the market
Walking on the first floor of the Huangjingjing Bauhinia Square, there is no difference in the lighting of the rows above the head; entering the underground garage of Lifan Research Institute in Beibei District, the lights are shining and shining. Surprisingly, however, these "lights" emit pure sunlight, and as long as the day is not black, it can be ensured that the room does not consume electricity. Where does this "black technology" come from?
After many inquiries, the reporter finally learned from Chongqing Qidi Science and Technology Park that these "lights" are from its park enterprise - Chongqing Mawei Technology Development Co., Ltd. Its founder, Peng Pinjia, has been dealing with the construction industry and has long been concerned about light-guided lighting systems.
She told reporters that the light guide lighting system is already a relatively mature technology abroad. There are only a few projects in our country. “Why don’t you do light guide lighting and become a porter of natural light?†She had the idea of ​​starting a business. With the introduction of light-guide lighting as a new technology for environmentally friendly lighting in 2010, and the introduction of relevant policies, she left the post for seven years, founded the company, and spent a year researching the market.
Developed into the first light guide lighting supplier
According to the statistics released by the National Bureau of Statistics, the annual power generation in 2012 was 4,937.77 billion kWh. According to China's lighting electricity consumption, which accounts for about 15% of the power generation, the electricity consumption for lighting in 2012 was about 740.67 billion kWh, according to 0.8 yuan/ In kilowatt-hour calculation, China's lighting power market capacity in 2012 was approximately 592.53 billion yuan.
"In accordance with the fact that light-guide lighting technology can replace 30% of lighting power consumption, it can save 177.76 billion yuan in lighting in 2012. That is to say, the market capacity of China's light-guide lighting technology in 2012 was about 177.76 billion yuan." Peng Pinjia, who researched the market, was very excited to see this series of figures. She was determined to take a share of this huge "cake".
Light guide lighting sounds simple, using physical principles to reflect sunlight, but it is not easy to achieve high reflectivity. Peng Pinjia worked with a team from a university and after many experiments, developed a light guide system with the function of lighting and amplifying light. The light pipe uses a special material that allows natural light to have a reflectance of 98%, meeting most indoor lighting requirements. At the same time, with LED lighting, the light guide lighting system can also be used at night.
As the first light guide lighting solution provider in Chongqing, after continuous development, they now have an industrial chain of R&D, manufacturing and sales. Since it was put into the market in 2013, it has been successfully installed in several buildings.
Calculate one year to save electricity costs of hundreds of thousands
Without electricity, it can also emit dazzling light. It can also be used to illuminate light. What kind of light guide system looks like? The reporter went to the scene to experience it.
At the scene, the reporter noticed that the light guide lighting system of Chongqing Malang Technology can be divided into two parts: the above ground and the underground. The ground is a lighting device (lighting device), such as the size of the floor tile, which is laid flat on the square and has two layers on it. Covered with bullet-proof glass, it can bear 300 kg. The lower part of the daylight is connected to the light-conducting part (light pipe), which looks like it extends from the ground. It is cylindrical and about half a meter in diameter, depending on the length.
The entire device extends from the ground to the bottom is a diffuser, its surface is covered with dense luminous points, looks like a "mushroom head" at a distance, the light emitted is softer than the fluorescent lamp, standing up and looking up, there is The feeling of nature's sunshine. Each set of light-guided lighting system can cover about 20 to 50 square meters of space, so that even indoors can meet the lighting needs, saving electricity and environmental protection.
But how much electricity can such a piece of equipment save? How much contribution can it make to environmental protection? Peng Pinjia calculated the account for the reporter. Take the parking lot of a factory park with 28 sets of equipment last year. It shows that a total of 82,000 kWh of electricity was saved in the whole year. According to the industrial electricity consumption of 1.5 yuan/kW, it saved more than 120,000 yuan for the plant. At the same time, it used 1.22 tons of standard coal for 10,000 kWh of electricity. This plant uses less than 100,000 tons of coal. “When installing a set of equipment, it only costs a few thousand yuan. It can be used for 20 years without damage. If it is 3 years, it will be returned to the original. The remaining 17 years are all free.â€
Promote technological innovation to "preempt" the market
“Light-guide lighting system is energy-saving, environmentally friendly and saves money. However, it has been difficult to promote in the past few years. Many customers have never heard of natural light lighting. In recent years, many places have begun to build 'green buildings', and the promotion of light-guided lighting is slightly better. Peng Pinjia said that in 2017, the market capacity of light-guided lighting technology was about 300 billion yuan, but this market has only developed less than 1%. Only continue to strengthen promotion and expand the market.
To expand the larger market, on the one hand, it needs to be continuously promoted in the market, so that more people know about this technology and let more buildings use this technology. On the other hand, technology also needs to be constantly upgraded to meet more diverse needs.
The reporter learned that Chongqing Malang Technology has developed a more intelligent light guide lighting system. This set of light guide lighting system is equipped with an intelligent control system, which can achieve automatic control and intelligent fill light. When the solar panel absorbs solar energy to charge the photovoltaic, it can avoid overcharging and discharging of the photovoltaic. In addition, according to the light condition, the artificial intelligence LED fills the light through the solar photovoltaic panel in the case of insufficient light, and truly does not consume Once electricity.
Recently, their new generation of light guide lighting system has been patented and is expected to be put into use in the second half of the year. Peng Pinjia said that he hopes that this generation of products can expand into a larger market, enabling more people to understand light guide lighting and know the advantages of light guide lighting technology.
Review
Market prospects, large enterprises need to develop in depth
Natural light has an inexhaustible, clean and pollution-free superiority. According to statistics, the cost of air pollution from the use of conventional energy sources in the world is about 10% of the fuel cost.
"In the long run, the prospect of natural light illumination is very large." Liao Wei, secretary general of Curvature Engineering, told reporters that there are not many domestic enterprises about natural light illumination, but because of the simple physical reflection of natural light illumination, product homogeneity is serious. Enterprises need to develop in depth. If the light guide lighting system is completely intelligent, so that it can be intelligently controlled and intelligently maintained, then everyone will accept it more. In addition, in the design of the design, it is also possible to customize the shape according to the customer's needs, to improve the selectivity, such as adding a pattern to the appearance of the light pipe.
