As the basic traffic equipment of road traffic, the setting of
Road Stud can be said to be very important. Widely used in road intersections, corners, bridges and other dangerous sections with potential safety hazards. It is used to guide driver or pedestrian traffic, facilitate dredging traffic, and thus help avoid traffic accidents and accidents. Because
Road Stud's effects are so dramatic, the quality of its products couldn't be lower. Do you know how to determine the quality of
Road Stud?
Measurement method of
Road Stud quality:
1. Raw materials:
Generally speaking, the thickness of the traffic signal lamp shell is generally better, all within 140mm, and the raw materials are generally pure PC materials, ABS materials, recycled materials and other materials. Among them, the quality of pure PC integrated
Road Stud shell material is the best.
2. Switching power supply:
The power switch basically focuses on the needs of anti-surge, power demand and charging and discharging of integrated traffic lights at night. When distinguishing, the black plastic lamp housing can seal the switching power supply and use it in the open air for 24 hours.
3. LED function:
LED lights are widely used in integrated traffic lights due to their advantages of environmental protection, high brightness, low heat, small size, low power consumption, and long life. Therefore, when determining the quality of traffic lights, this is also an aspect that requires serious consideration. Generally speaking, the size of the chip determines the price of Road Stud.
The low-end all-in-one
Road Stud on the market uses 9, 10-minute chips. Users can use the visual comparison method to determine the size of the chip, which directly affects the brightness and life of the LED, and then affects the brightness and life of the integrated
Road Stud. If you want to determine the function of the LED, you can add the appropriate voltage (red and yellow 2V, green 3V) to the LED, use a piece of white paper as a setting, point the glowing LED light to the white paper, and a high-quality LED will appear traffic light. There will be a regular circular light spot, and the light spot of an inferior LED will be an unmeasurable shape.
4. National Standards
Road Stud accepts inspections, and the period for inspection statements is two years. Even if ordinary
Road Stud products get the inspection form, the investment cost is not less than 200,000 yuan. Therefore, there is no relevant national standard statement to determine the quality of
Road Stud. We can use the number and company name on the test report to call the Ministry of Public Security and ask the Traffic Safety Product Quality Supervision and Testing Center whether it is true.
