Fill in the blank of heavy enterprises developed a "chameleon" LED Street

The new normal daily economic development in Chongqing, the implementation of innovation driven development strategy to achieve economic development power conversion has become the consensus of all walks of life. At the same time, the public entrepreneurship, innovation to Liaoyuanzhishi throughout the vigorous development, innovation has become the most eye-catching scenery which.

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. From today, this newspaper launched the "innovation side story column, showing from the various industries in the field of innovation, achievement and experience of the story, please pay attention.

In September 29th, Jiulongpo chenjiaping tunnel, workers are using mobile phone software to control the "chameleon" LED light color.

At the beginning of this year, Losangeles city hall announced a plan, will be the city's 160 thousand LED lights into mobile communication chip. These street lights "Internet", the municipal personnel using computer, can accurately control on single lamp switch time and brightness.

In fact, street management is similar to the way in Chongqing, is nothing 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.

Yellow white for LED lighting ""

A LED street lamp, why do we need a variety of colors? The city lighting field for years "Huang Baiguang for".

In 2009, Chongqing Green Technology Development Co. Ltd. legal representative Su Chengyong to see such a report:

In the 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 after a few years, the competent department for receiving complaints from the public, said the autumn season when cold white LED light irradiation of the pavement is cold, the impact of travel. In desperation, the municipal department had to put the energy-efficient LED lights and replaced the energy consumption of the yellow light high pressure sodium lamp.

In foreign countries, but also because of cold white LED lamp light glare, caused a lot of controversy. 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, city lighting with yellow light, white light is not absolute. For example, in the hot summer, the white light will make people feel cool; in the cold winter, warm yellow light will make people feel warm.

The lamp power consumption has accounted for 40% of the city public electricity, the promotion of energy-saving lamps such as LED lamp is represent the general trend." 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.

Targeting this market space, in 2010, Su Chengyong began the development of chameleon LED lamp.

"Chameleon" lights fill the gaps

D, easy to say, hard to do.

LED is a remote control system and intelligent lighting, including more than a dozen smart chip and hundreds of electronic components. A little carelessness will lead to failure." Speaking of the development process of hard, Su Chengyong tone becomes heavy.

After nearly three years of development, dozens of Su Chengyong failed to solve the technical problems of LED street lamp "color" -- the higher the temperature, the blue ray spectrum more light is more dazzling. 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).

Let Su Chengyong happy is he in 2013 to the State Patent Office patent, patent search, the new program shows, domestic and not the technology. Because of his invention of advanced technology enterprises, where he was awarded the "national high tech enterprise".

The new management mode to help "chameleon" attack the camp pulling 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. Sichuan, Jiangxi, Jilin, Guizhou, Hunan and other customers for the product expressed interest.
