Under the new normal economic development, the implementation of innovation driven development strategy, the realization of economic development power transformation has become consensus. At the same time, public entrepreneurship, many people's innovation in a prairie fire, in various places to flourish, innovation has become one of the most eye-catching landscape.


For Chongqing, the release of their wisdom through innovation, can promote economic development from a factor driven, investment driven to innovation driven, boost industrial structure optimization and upgrading, promote more "Chongqing create" to the country, to the world. Starting today, the newspaper launched the "innovation stories around" column, showing innovation stories and experiences from all sectors of the city, and achievements, so stay tuned.


Earlier this year, the Losangeles city hall announced a plan to put the city's 160 thousand LED street lights into the mobile communications chip. After the street lights "on the Internet", city officials use computers to fine tune the time and brightness of a single street light switch.


In fact, a similar street lamp management in Chongqing has long been new. Yuzhong District goose Ridge Tunnel, Jiulongpo chenjiaping tunnel, two years ago by a Chongqing company developed "chameleon" (Internet plus LED lamp color temperature LED remote intelligent control system), according to the seasonal variation of the remote control on the light color and brightness.


LED lighting "yellow white light" dispute"


A LED street lamp. Why do you need a variety of colors? This also has to continue in the field of urban lighting for many years, "Huang Baiguang's argument" about.
In 2009, Chongqing Green Technology Development Co. Ltd. legal representative Su Chengyong to see such a report in LED Street "ten city lights" pilot, part of the city trunk road lamps replaced the LED lamp cold white light, the initial effect is good. But a few years later, the competent authorities received complaints from the public, saying that the cold and white LED lights during the fall and winter season seemed cold and affected the trip. In desperation, the municipal department had to replace the energy-efficient LED lamp with a large yellow light high pressure sodium lamp.
In foreign countries, the cold white LED street lamp also caused many disputes due to the glare of the light. Such as Berlin, California residents had strongly opposed the lights replaced with LED lights, the reason is "original after dark warm yellow lights dotted the winding mountain road, lost the original poetic romance for LED street lights," white "."


In fact, urban lighting with yellow light, white light is not absolute. For example, in hot summer, white lights can make people feel cool, but in cold winter, warm yellow lights can make people feel warm.


"Street light power consumption has accounted for 40% of urban public electricity consumption, and the promotion of energy-saving lamps, such as LED lights, is the trend of the times."." Su Chengyong think, if every LED lights light color can be like a chameleon like that with the changing seasons, yellow white for street lighting will not exist, if can also incidentally solve the haze day lighting problem, LED Street certainly competitive in the market more than the traditional high pressure sodium lamp.
Aimed at this market space, from 2010 onwards, Su Chengyong began to "chameleon" LED street lighting research and development.


"Chameleon" street lights fill the gap


R & D is easier said than done.


"A LED remote control system and smart lamps include more than a dozen smart chips and hundreds of electronic components. A little carelessness will lead to failure." Talking about the hardships of the R & D process, Su Chengyong's tone became heavy.


After nearly three years of research and development, dozens of failures, Su Jie to solve the "LED Street color" discoloration of the technical problems - the higher the color temperature, the more blue spectral rays, the more dazzling light. Considering the people's feelings, in the spring and autumn, the lamp color temperature adjustable 3700K (Nuan Baiguang); in the summer, the lamp color temperature adjustable 4000K (Zheng Baiguang); in winter, the light color temperature adjustable 3500K (Qian Huangguang); in the haze, and the lamp color temperature adjustable (3000K yellow light).
To Su Chengyong's pleasure, in 2013, when he applied to the State Patent Office for patent applications, the patent search process showed that the technology was not available in the country. Because of the advanced nature of his invention, his enterprise was awarded the title of "national hi tech enterprise".
New management model to help "chameleon" attack camp pull Village
Two years ago, "chameleon" LED street lamp products were put into the eling tunnel in Yuzhong District, Jiulongpo chenjiaping tunnel, the city and district departments of lighting test, saving 70.5% than traditional sodium lamp.
Although the "chameleon" LED lamp LED lamp with high cost than the average of nearly 60%, but 10% higher than ordinary LED lamp brightness, long life of more than one times; the contract energy management mode of operation of lighting energy saving project, 10 years to recover the cost.
The so-called energy management contract, refers to the energy service company (government) signed a contract with the user, the user in the (government) under the premise of not spend a penny, the energy service company for the user (government) to provide such diagnosis, financing, transformation services, and obtain reasonable profits through the sharing of energy efficiency investment and recovery.
With this model, Su Chengyong will be his "chameleon" series of products have been marketed to LED street G50, Huashan Tieshan Ping Yu Fu highway tunnel project of energy-saving lighting. Customers in Sichuan, Jiangxi, Jilin, Guizhou and Hunan also expressed interest in the product.
"We will continue to tackle key issues to further reduce production costs." Su Chengyong said that his greatest wish is to hope that more "China created" LED products to the world.
