LED signal lights are ubiquitous in our daily lives. LED signal lights are widely used in hazardous areas, such as intersections, curves, and bridges, to guide drivers and pedestrians, ensure smooth traffic flow, and effectively prevent traffic accidents.
Given their crucial role in our lives, high-quality standards are essential. We’ve also noticed that prices vary among LED signal light manufacturers. Why is this? What factors influence the price of LED signal lights? Today, let’s learn more from Qixiang, an experienced LED signal light manufacturer. We hope this helps!
Qixiang LED signal lights feature a high-transmittance, weather-resistant lampshade, ensuring clear signal display even in challenging weather conditions such as strong sunlight, heavy rain, and haze. Core components undergo rigorous testing in high and low temperatures, vibration resistance, and long-life operation tests, ensuring stable operation in extreme environments ranging from -40°C to 70°C, with a mean time between failures (MTBF) that far exceeds industry standards.
1. Housing Material
Generally speaking, the housing thickness of a standard LED signal light is under 140 mm, and materials include pure PC, ABS, and recycled materials. Pure PC is considered the highest quality.
2. Switching Power Supply
The switching power supply primarily addresses surge protection, power factor, and the charging and discharging requirements of the LED signal light’s nighttime yellow flashing power supply. If necessary, the switching power supply can be sealed in a black plastic housing and used outdoors around the clock to observe actual performance.
3. LED Performance
LED lights are widely used in traffic lights due to their environmental friendliness, high brightness, low heat generation, compact size, low power consumption, and long life. Therefore, LEDs are a key factor in evaluating traffic light quality. In some cases, chip size determines the cost of a traffic light.
Users can visually assess chip size, which directly affects the light intensity and lifespan of the LED, and thus the light intensity and lifespan of the traffic light. To test LED performance, apply an appropriate voltage (2V for red and yellow, 3V for green). Place the illuminated LED facing the paper against a white paper background. High-quality LED signal lights produce a regular circular light spot, while low-quality LEDs produce an irregular light spot.
4. National Standards
LED signal light must undergo inspection, and a test report must be issued within two years. Even for standard-compliant traffic lights, obtaining a test report can be expensive. Therefore, the availability of relevant national standard reports is a crucial factor in determining the quality of traffic lights. LED signal light manufacturers will provide different quotes based on the above factors. We hope this information is helpful.
