Fill in the gaps in the development of a "chameleon" LED street lamp

Chongqing Daily News under the new normal economic development, the implementation of innovation driven development strategy to achieve economic development momentum has become a consensus of all walks of life. At the same time, the public entrepreneurship, people's innovation in order to start a prairie fire in the booming development, innovation has become one of the most eye-catching scenery.

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 innovative stories around the column, showing the story from the city's industry, the field of innovation and experience, achievements, please pay attention.

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

Earlier this year, the Losangeles city hall announced a plan to put the city's 160 thousand LED street lamp implanted mobile communication chip. These street lights after the Internet, municipal staff use computers, single street lamp switch time and brightness for precise control.

In fact, a similar street management, in Chongqing is not 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 of the yellow white dispute"

A LED street lamp, why do you need a variety of colors? This is also from the field of urban lighting for many years, Huang Baiguang's argument.

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

In the LED street lamp ten city million pilot, some cities to replace the trunk road lights cold white light LED, the initial effect is good. But a few years later, the competent authorities received complaints from the public, said the autumn and winter seasons when the cold white LED light irradiation of the road looks bleak, affecting travel. In desperation, the municipal department had to put the energy efficient LED lights into a large energy consumption of yellow light high-pressure sodium lamp.

In foreign countries, cold white LED street light is also dazzling, causing 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, 'scary' pale. "

In fact, urban lighting with yellow light, white light is not absolute. For example, in the hot summer, the white light will make people feel cool; and in the cold winter, warm yellow light will make people feel warm.

Street lamp power consumption has accounted for 40% of the city's public electricity, to promote energy-saving lamps such as LED lights is the trend. "Su Chengyong think, if every LED lights light color as" chameleon "that change with the seasons, yellow white for street lighting will not exist, if can also incidentally solve the haze day lighting problem, LED Street certainly out market competition more than the traditional high pressure sodium lamp.

Aimed at this market space, since 2010, Su Chengyong began to chameleon LED street lamp R & D.

"Chameleon" street lamp to fill gaps

R & D, easy to say, hard to do.

"A set of LED remote control system and intelligent lamps, including a dozen intelligent chips and hundreds of electronic components. A little carelessness will lead to failure. Speaking of the hardships of the research and development process, Su Chengyong tone becomes heavy.

After nearly three years of research and development, dozens of failures, the Soviet Union to solve the LED street lamp color change, the technical problem - the higher the color temperature, the more blue spectrum 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).

Let Su Chengyong happy is that in 2013 when he applied for a patent to the State Patent Office, the patent search program shows that the domestic did not have this technology. Because of the advanced nature of his invention, his company was awarded the title of "national high tech enterprise".

The new management model to help "chameleon" attack Camp 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 also expressed interest in this product.
