Tunnel light is used more and more widely, but in the scientific research and application in the specific, all the shortcomings and technical inadequacy of the tunnel light can not be avoided, and there is no way to get rid of it.
 
Tunnel light takes green environmental protection as its key product selling point. It does not have a huge waste of resources, but from a technical point of view, the collection and storage of electric energy must be based on ideal climate standards, not just a system. The cost must continue to rise, and it is different from the main performance of the system itself, which is the main performance of environmental protection and energy saving and the theme style of development and utilization.
 
In addition, some difficult problems that seem to be very technically simple, Tunnel light manufacturers must also use relatively high-cost capital to deal with in specific applications, including:

1. The problem of centralized management. If the electrical equipment route is not applied, there is no way to maintain the centralized management and real-time monitoring that are critical for tunnel lights. However, if the electrical equipment route is further equipped, it will not only increase the cost, but the product will be in the "product selling point". The actual meaning of "on" has weakened again
 
2. Tunnel light rechargeable battery life, battery life and other operating electronics life are usually less than LED life. This brings about many problems that must be dealt with in order to maintain the long life of the entire system, and it will also cause Higher maintenance cost
 
3. Because the system uses DC battery, it is easy to be stolen, so anti-theft is the problem of the system.
 
In addition, there is also the general net weight problem of installing solar panels with a high aspect ratio, which brings about the improvement of the wind resistance of the Tunnel light design scheme and the increase of the cost. These problems are all caused by the solar power LED lighting system. Difficulties that cannot be dealt with in many ways.
