We can generally observe that the quality of public facility products is always selected from the best available options. This choice is not due to financial abundance, but rather for safety and durability considerations. Therefore, the quality of the traffic signal is subject to very strict requirements.
In general, the production of traffic signals must adhere to the following points:
1. Framework Requirements
The framework is designed to withstand exposure to wind and sunlight, requiring a hot-dip galvanizing process during production, and must comply with national standards. The framework cannot use clamps or brackets to make connections.
2. Color
The color is typically unified in black. This choice is not only aesthetically pleasing and lightweight but also simplifies maintenance and installation.
3. LED Selection
The lifespan of the LED light source is extremely important. It should have a visibility range of approximately 500 meters, with a lifespan requirement of no less than 80,000 hours. Additionally, it is crucial to ensure that the color of the light source remains unchanged to guarantee the normal operation of the traffic signal without being affected by external factors.
4. Component Aging Inspection
Given that these signals will be used outdoors for extended periods, the components and parts must also meet certain aging requirements. Only through repeated testing and inspection can the final determination be made.
The production process of traffic signals must be carried out in accordance with national standards, as it pertains to public safety. Therefore, the lifespan and stability of each component need to undergo repeated testing for final confirmation. Moreover, the selection of the LED light source is made with great caution, including its power and voltage requirements.
