Zhouming Technology hits the three sets of combination punches for the Guangzhou-Shenzhen high-speed LED street light

The Guangzhou-Shenzhen Expressway LED streetlight renovation project is an exemplary streetlight renovation project in Guangdong Province and even in China. Its technological content and operation management have set a new benchmark in the industry. When the CCTV news broadcast was broadcast on this project, it was described as “a project that the Guangdong Provincial Science and Technology Department is proud of”. It is Zhouming Technology that continuously strengthens the investment in research and development, pursues excellence in quality, and uses a good operating model. It has won these three sets of combination punches and won this pride, creating the first in five industries.

Beat the "technical" boxing

As is known to all, LED street lamps have advantages in energy saving and environmental protection compared with high-pressure sodium lamps. However, LED street lamps generally adopt simple constant current control methods, and lighting control cannot be performed as needed, especially in the case of no-vehicle traffic in the middle of the night. Street lights are also illuminated at normal brightness, both wasting power and affecting the life of street lamps. Therefore, how to realize the "secondary energy saving" of LED street lamps on the basis of "one energy saving" has become the focus of enterprise research and development. Zhou Ming Technology, which has always been at the forefront of the industry, has also studied the intelligence of street lamps.

The fourth-generation streetlight products of Zhouming Technology, which is used in Guangzhou-Shenzhen Expressway, use the industry-leading intelligent remote stepless dimming control system to remotely control the use time, brightness and temperature to meet the lighting effects of different usage scenarios. It also has an environment-adjustable adjustment function that automatically adjusts the brightness according to the ambient light to create a comfortable lighting space. During use, it can remotely control LED street light switch and dimming remotely, and can also feedback voltage or current, status inquiry, fault alarm, etc., so that the street light can be illuminated as needed to achieve secondary energy saving.

The entire process of Guangzhou-Shenzhen Expressway relies on intelligent control for management and monitoring. As the longest LED street light application project in China, in order to better manage and monitor the lamps in real time, the company has invested in the intelligent control system. A lot of time and manpower, with the chairman Lin Yifeng as the project leader, after repeated trials, the company successfully developed the current power carrier intelligent control system, realized single-lamp control and real-time monitoring, timely reported the working status of the lamps, and can be intelligent Remote stepless dimming can realize the dimming and energy saving function of saving energy twice as needed.

The products used in the Guangzhou-Shenzhen high-speed LED lighting renovation project are also the independent research and development achievements of Zhouming Technology. It is understood that the fourth generation of intelligent street lamps from design to product development, and then to production, are independently completed by Zhou Ming Technology, which fundamentally reduces production costs. The smooth implementation of the Guangzhou-Shenzhen high-speed LED lighting renovation project has achieved a good demonstration role in the domestic public lighting engineering field and successfully established the industry benchmark.

Beat the "quality" boxing

As the core high-speed trunk line in Guangdong Province, the Guangzhou-Shenzhen Expressway has a total length of 122.8 kilometers. The lane is designed for two-way six-lane driving. The whole line is equipped with street lighting. In addition to the hard requirements of the street light's efficacy and service life, energy conservation has also become an important indicator of this project.

To this end, Chau Ming Technology replaces the original 250W high-pressure sodium lamp with 100W LED street light. After the completion of the engineering transformation, it can achieve energy saving of more than 70%. According to the number of 6280盏 LED street lamps in this project, it lights up for 10 hours every day, saving The power is down to 12560 degrees / day. In terms of lighting effects, the high-power LED lamps of Chau Ming Technology are beautiful in appearance, and the illumination and brightness are in full compliance with the requirements of road lighting for main roads. In the case of a color temperature of 4000K, the best solution is achieved with a color rendering index greater than 65, a luminous efficacy greater than 120 lm/W, and an average ground illumination of 20 lx.

Due to the special driving environment of the expressway, there are very strict requirements for lighting fixtures. It is well known that the yellow light penetration of high pressure sodium lamps is superior to the white light penetration of LED lamps. Then, in the harsh natural environment such as rain and fog, can the inductivity and penetration of LED lighting products meet the needs of expressways?

Faced with industry problems, Zhouming Technology has adopted lighting products with a color temperature of less than 4000K in the renovation project of Guangzhou-Shenzhen Expressway, which not only satisfies the illumination demand, but also enhances the penetration of the light, and the lighting application is more comfortable. At the same time, Chau Ming Technology integrates the lightning protection wall function in the intelligent control system, and the lightning protection voltage is 10KV, thus ensuring that the lighting products can also be used normally under wind and rain conditions. Taking into account the special weather characteristics of “multiple typhoons” in Guangdong Province, this project is specially equipped with anti-drop device. On the basis of the light pole structure itself can resist the 12-level wind, the protective measures are added to ensure the safety of the product to the utmost extent. use.

Beat the "cooperation" boxing

According to Ye Jingtu, deputy director of the Guangdong Provincial Department of Science and Technology, the government subsidies for the promotion and application of LEDs accounted for about half of the previous year. Last year, the subsidies for LED products in Guangdong Province reached 450 million yuan. The Guangzhou-Shenzhen high-speed LED streetlight renovation project adopts EMC (Energy Management Model). Until now, the government's finances have no subsidies at all and no budget is needed.

This new type of cooperation between government and enterprises not only reflects the innovation of cooperation mode, but also has far-reaching significance. While supporting the development of the industry, the government has realized the transformation of government functions and gradually returned the market to the market. More energy is placed on the planning and guiding of the industry, and the government functions are neither “offside” nor “lost”.

This benchmarking case also provides more cooperation ideas for the government and enterprises. Ye Jingtu, deputy director of the Guangdong Provincial Department of Science and Technology, said: In planning the guidance of the LED industry, it is necessary to prevent blindly expanding investment in upstream enterprises and actively promote the support of downstream application enterprises. This is in line with the director of Shenzhen Zhouming Technology Co., Ltd. Lin Linfeng believes that the products of downstream application enterprises have certain research and development advantages, and some leading enterprises have independent core technologies, which are conducive to the formation of core competitiveness and help to establish the market position of the industry.

With the combination of “Technology, Quality and Cooperation”, Chau Ming Technology has realized the high-quality transformation of Guangshen high-speed LED street lamps. In the future, Chau Ming Technology will take this demonstration project as an opportunity to continuously increase investment in science and technology research and development, continuously strengthen its independent research and development capabilities, and strictly control quality.
