LED Street Light Tunnel Light Development Prospects

In recent years, with the continuous maturation and development of LED lighting technology, performance and safety standards have been fully recognized at the national level, industry level and local level, and a large number of such standards have been formulated. In general, safety and performance indicators are not a problem in the development trend of street lamp tunneling technology.

The problem of maintainability, replaceability, and standardization of the interfaces of the lamps has become the key to restricting the widespread use and promotion of these public lighting products. In terms of street lamps, although the penetration rate of LED street lamps in the domestic market has become higher and higher in the past few years, it has been observed in larger cities and capital cities such as Beijing, Shanghai, Nanjing and Suzhou. The idea of ​​large-scale replacement but there is still no plan. The reason is that the lack of maintainability of the current LED street lamps and the replaceability of products from different manufacturers has caused the owners' concerns, which seriously restricts the large-scale application and promotion of LED lamps.

Even if the lifespan of LED lamps can exceed 50,000 hours, the owners are also faced with the problem of replacement after 6 years. For traditional lamps, the owner only needs to replace the light source. Generally, the lamp lamp shell can have a service life of more than 20 years. For the integral LED lamp, the owner needs to replace the entire lamp, which brings the following results: a lamp itself has a high replacement cost, and the replacement operation is difficult and costly. Replacement of new lighting fixture owners may re-tender, change the original tunnel maintenance procedures, and bring new problems to maintenance units and decision-making units. In addition, if the lamps of different manufacturers cannot be interchanged, the owners will be constrained by the manufacturers during use, which affects the enthusiasm of the owners in using LED lamps. Therefore, based on this development, the development of "interface standardization, light source modularization, intelligent control" LED lamps for the extensive application of LED has a very important significance.

The core idea of ​​the light source modular street light tunnel light is: the LED light source is a module, the LED light source module in the lamp energy saving and environmental protection group, the power source as the replacement body, independent replacement in the maintenance process; the technical difficulty to be solved is to protect the light source The reliability of the module, but also to achieve the easy replacement of hands-on operation at the scene; the standard to achieve the unity of the interface and interchangeability of different manufacturers.

Finally, the biggest advantage of LED as a new light source is intelligent control. Therefore, the protocol corresponding to intelligent systems and systems used for tunnel lighting should also be unified and standardized. However, the standardization of this interface has a bearing on the development trend of the industry. It is not that manufacturers make their own cars behind closed doors, but rather lead the relevant units. Manufacturers participate in jointly solving some key technical points. First, they gradually unify the use of small-scale applications. process. At present, the international Zhaga Alliance has established relevant organizations in China, including the Semiconductor Industry Alliance, the Shanghai Municipal Construction and Communications Commission, the Chongqing Tunnel Traffic Design Institute, and the Guangdong Provincial Science and Technology Department, and has actively carried out the interface standardization work in the field of road tunnel lighting. All have been applied in a small area. Ultimately, the scope of the promotion and application of these standards depends, on the one hand, on the compulsory promotion of government departments and on the other hand, the acceptance of users.
