CSA016-2015 LED lighting application and interface requirements formulated by national semiconductor lighting engineering research and development and industry alliance in 2017: the standard of the road lamp/tunnel lamp of the non-integrated LED module realizes the standardization of the light source module of the LED road lighting through the setting of the standard, and the product meets the requirement of interchangeability. The light source module meeting the standard requirement has the advantages of light source dispersion and good heat dissipation performance, but has the defect of high light distribution difficulty and has no small influence on the light distribution requirement of the road which is gradually growing nowadays.

Based on the drawback that the light source module that traditional lamp pearl array constitutes exists, my company focuses on the high-power light source that COB packaging technology formed, can realize fine grading effect, satisfies the road demand. However, the COB light source is adopted to solve the problem of high heat dissipation requirement caused by light source concentration, so that the first generation light source module product of the company adopts a sunflower radiator structure to perform heat dissipation treatment on the COB light source, the whole light source module is a circular module with the diameter of 160mm, and the rated power is 60W-75W. The light source module is difficult to match with the standard in the current industry in the aspects of popularization and application. Most street lamp replacement projects adopt the CSA016 standard which is mainly reflected in the structural size and interchangeability of the light source module, and the most common module with the sunflower radiator structure in the market does not meet the standard.

In addition, most of the current light source modules have larger diameters, the common lamp shells can only accommodate 2-3 light source modules, and if 4 light source modules are used, the lamp shells adopting double-light-source cavities have smaller choice and high cost. Therefore, in order to meet the standard requirements and better promote the market acceptance of products, it is necessary to develop a light source module which can meet the CSA016 standard, and meanwhile, the radiator of the light source module has the characteristics of uniform heat dissipation, good heat dissipation effect, less used materials, small overall weight and volume, low cost, space saving, good portability, convenience in replacement and the like.

The novel city of high informationization and wisdom ization is built, just integrate above-mentioned various intelligent system to a platform, need spend a large amount of manpower and materials and organize network again, just so need rebuild the city, lay the circuit, it is extremely inconvenient at the actual implementation in-process.

In order to enhance the understanding of the city, on the basis of the traditional city monitoring means, information perception terminals with more quantity, richer functions and higher intelligent degree need to be added. How to arrange the information perception terminals is a difficult problem in the construction of smart cities.

Street lamps are indispensable lighting tools for people to go out, and are an important ring of urban infrastructure. With the development of modern cities and the arrival of the era of intelligent hardware and cloud computing big data, the innovation of street lamps can bring more upgrading on other functions for the cities.
