What are the possible causes of common malfunctions in DOB flashing

What characteristics of lighting fixtures make them suitable for outdoor lighting engineering selection

Outdoor LED line lights are one of the lighting fixtures used in large-scale engineering buildings for urban lighting. If they flash, what are the common faults? LED bead manufacturers come to explain to us.

There are four common reasons for the flashing of outdoor LED line lights: 1. The output power transformer of the lamp is not ready, the main parameters do not match, and the winding resistance inside the structure is not enough or too much, resulting in the key magnetic saturation state or insufficient inductance of the lamp; 2. Common faults in integrated operational amplifier circuits; 3. The working current of the lamp load is too high or the working voltage of the load is too low, which is less than the output voltage of the switching power supply and leads to fully automatic maintenance; 4. The sampling circuit principle of the working voltage of the lamp is not scientific, and the power supply voltage is too low, which is significantly lower than the normal working voltage, resulting in the inability to start the switch power supply. If all the flashes occur, it may be due to the faulty transformer or the unstable current from 220V to 12V, resulting in a decline in the quality of the LED itself.

Therefore, line lamp manufacturers suggest that when choosing outdoor LED line lamp products, everyone must find reliable large and medium-sized LED line lamp manufacturers, as high-quality first tier brand products have quality assurance. The actual effect of irradiation during use can be established and ensured.

In recent years, the order information of LED lighting fixtures has increased many times compared to the past. Due to the fact that many engineering project owners love to choose LED lighting fixtures in outdoor urban lighting, why have LED lighting fixtures become the choice for outdoor urban lighting? The manufacturers of line lights have summarized the following aspects:

1. The current method used for LED lighting fixtures is DC power supply, which is suitable for outdoor or solar power generation.

2. In public places, it is often necessary to use human body sensing lights, such as sound and light control switches, so it is necessary to switch the power switch frequently, which makes it necessary to use LED for the service life and durability

3. Road lights, or some overpasses, can adjust their brightness during periods of low pedestrian and traffic flow, so LED dimming must be used.

4. In some unique lighting fixtures, such as warehouses, explosion-proof areas, etc., tungsten free lighting fixtures must be used. Some ultra-low temperature venues, such as ice rinks or large and medium-sized refrigerated warehouses, require lower temperature lighting fixtures, such as LED lights that use cold light sources.

5. LED illumination is a fixed light, suitable for highway, bridge, and tunnel construction.

So, LED lighting fixtures may be fully popularized and more widely used in the future. Whether it is outdoor urban lighting, general engineering lighting, or daily life applications, the attention of LED lighting fixtures will continue to grow, which will be a top priority for urban planning and construction in China in the future.
