As an expert in domestic research projects on green lighting and urban environmental protection, Professor Chen Yuli's research and opinions in related fields deserve to be concerned by the industry. Aladdin Lighting Network specially interviewed Ms. Chen Yuli and listened to his questions about Suzhou urban lighting construction and understanding the regional and cultural concepts in Suzhou urban lighting.
Aladdin Lighting Network reporter auspicious: In your paper, you can see that you are very concerned about the "geographical" and "cultural" connotations of lighting. You mentioned "to use light to express culture" and "light has obvious regional characteristics" - please read it in detail.
Chen Yuli: Modern lighting purposes are not only functional, but also decorative. Light is not only used to directly serve social interaction and labor life, but it is also an expression channel of emotion, thought and culture. Lighting not only meets the purpose of production and safety, but also the function of landscape, business and culture. The use of light sources and the development of lighting have brought a light culture to mankind. It is self-evident that culture has obvious regional characteristics. Then, just like using any other means to express culture, if you want to use light to express culture, light has obvious regional characteristics. Using different lighting methods combined with local scenes, you can express different emotions or ways of thinking, or you can use light to express different ideas and cultures. The form and effect of lighting selected in a region has a lot to do with its regional culture and ethnic characteristics.
Each city has its own cultural heritage and its own cultural aesthetic perspective. When planning and designing lighting, the characteristics of the city and the regional characteristics of the city should be taken into consideration, so that the combination of urban lighting and urban cultural characteristics makes lighting compatible with regional characteristics and urban characteristics. It is necessary to take into account the lighting style, lighting method, lighting time, lighting color and other aspects, fully consider the city's characteristics and natural conditions, showing the unique culture and connotation of the region. The combination of functional lighting and landscape lighting to achieve harmony and unity is an extremely important design concept.
Only by combining with the characteristics of the city can the design effect reflect the characteristics of the whole city and the characteristics of the region, and it is accepted by the local residents. Considering the cultural taste of lighting from the aspects of lighting fixtures, lighting and the color tone of the lighting, the harmony between urban lighting and urban cultural taste can be achieved.
Aladdin lighting network reporter auspicious: Suzhou as a fast-developing modern city, urban lighting inevitably to highlight the commercial atmosphere, how do you think the realization of the unification of business and culture? In terms of lighting construction, how to make commercial Suzhou and garden Suzhou coexist and develop together in a healthy way?
Chen Yuli: As a fast-developing modern city, Suzhou's urban lighting is inevitably a commercial atmosphere. At the same time, she is a city with a long history. Her development cannot be separated from her history. Her lighting must reflect her history and her culture. In fact, both business and culture are not necessarily opposite and can be completely unified. In modern times, Suzhou has always been a central city with a wealthy side. It has a highly developed business. The lighting of commercial atmosphere can also be used with different colors, shapes, lamps, and local architecture. Way to achieve.
How to make commercial Suzhou and garden Suzhou coexist and develop together is a very complicated topic. More broadly, how to make modern Suzhou stand on the shoulders of historical Suzhou, both complete inheritance and good development, this is a historical issue that is difficult to solve and must be solved.
In the specific layout of the Suzhou city, the centralized business district and the famous gardens should be separated and have appropriate lighting. At the same time, it is also possible to integrate the elements of the garden into the lighting of the commercial area, so that the architectural layout and lighting form of the commercial area have the unique charm of the garden Suzhou and the cultural Suzhou. From the aspects of lighting style, lighting mode, lighting color, background configuration, etc., functional lighting and landscape lighting are organically combined to express the unique historical culture of Suzhou, realize the harmonious unity of commercial Suzhou and garden Suzhou, and coexist and develop together.
Aladdin Lighting Network reporter auspicious: If you want to define the ideal lighting environment in Suzhou, what words would you use?
Chen Yuli: I want to use the following vocabulary to express the ideal lighting environment in Suzhou:
Water town garden soft and elegant history beyond

Aladdin lighting network reporter auspicious: No doubt Suzhou is a cultural city, but also a city with rich regional characteristics, "Jiangnan Water Town" has become its unquestionable sign. How do you think about these characteristics in urban lighting planning and design? How to use light to reflect the culture of Suzhou?
Chen Yuli: The cultural image of a city reflects the degree of urban civilization development, and light culture has increasingly become an important part of modern cities. Beautiful, comfortable and harmonious lighting also reflects the cultural taste of a city. In a modern urban environment, creating a suitable light environment can improve the image quality of the city and the quality of life of people.
Many domestic night lighting projects, such as Beijing Tiananmen Square, Chang'an Street, Shanghai's Bund, and Oriental Pearl Tower, reflect the unique characteristics of the city. The night illumination reflects the state of the city at night different from the day, and shows the unique city image and cultural characteristics of each city at night.
For Suzhou, this garden city with a history of more than 2,500 years mainly reflects the small and unique gardens of Suzhou, the simple and elegant ancient buildings and the characteristics of the Jiangnan water town. It integrates gardens, ancient buildings and water through the expression of light into the night scene. in. Let people feel comfortable, peaceful, soft, and quiet, bringing the beauty of the night to people.
Suzhou city night lighting design is to fully explore the regional culture, through the language of light to portray and express, fully display the regional characteristics, a better combination of Suzhou's humanities and geographical factors, showing the "garden city" of Suzhou "Jiangnan Water Town" and "Historical and Cultural City" combine the masculinity of the building with the feminine beauty of the water to form a unique urban nighttime illumination, which represents the unique Wu culture of Suzhou. The landscape reflects the cultural heritage, and the culture is also sublimated in the rational construction of the landscape, knocking out the harmonious notes of people and scenery.

What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
