LED Solar Signal Lights are light and color signals that are alternately changed at a specified time. They are usually set at intersections or other special locations to assign the right of way to vehicle drivers and pedestrians, and to control the traffic control of their stopping and turning facility.
LED Solar Signal Lights are widely used in highway intersections, curves, bridges and other dangerous road sections with potential safety hazards. The quality requirements for its products are definitely not low. Then you know how to identify the quality of LED Solar Signal Lights, and what are the factors that affect the price of LED Solar Signal Lights?
Factors affecting the price of LED Solar Signal Lights:
1. Shell material:
Generally speaking, the thickness of the LED Solar Signal Lights shell of the male model is generally relatively thin, all within 140mm, and the materials are generally pure PC material, ABS material, recycled material, miscellaneous material, etc. Among them, the quality of the traffic signal light shell material made of pure PC material is the best.
2. Switching power supply:
The switching power supply mainly focuses on the charging and discharging requirements of anti-surge, power factor, and yellow flashing power of traffic lights at night. During identification, the switching power supply can be sealed in a black plastic lamp shell and used in the open air all day long to see the specific usage.
3. LED performance:
LED lights are widely used in traffic lights because of their advantages of environmental protection, high brightness, low heat, small size, low power consumption, and long service life. Therefore, when evaluating the quality of LED Solar Signal Lights, this is also required. An aspect for careful consideration. In general, the size of the chip determines the price of the traffic light cost.
The low-end LED Solar Signal Lights on the market have chips that last for 9 or 10 minutes. Users can use the visual comparison method to identify them. The size of the chip directly affects the intensity and life of the LED light, thereby affecting the light intensity and life of traffic lights. If you want to identify the performance of the LED, you can add an appropriate voltage to the LED (red and yellow 2V, green 3V), use a piece of white paper as the background, turn the light-emitting LED towards the white paper, and the high-quality traffic light LED will show the rules The circular spot of the LED, while the spot of the inferior LED will be an irregular shape.
4. National standard
LED Solar Signal Lights are subject to inspection, and the inspection report period is two years. Even if the conventional LED Solar Signal Lights products get the inspection report, the investment will not be less than 200,000. Therefore, whether there is a relevant national standard report is also an aspect used to identify the quality of traffic lights. We can take the serial number and company name on the test report to inquire whether the quality supervision and testing center of traffic safety products of the Ministry of Public Security is true.
