Some Common Problems Regarding LED Street Light

As an important part of urban infrastructure, road planning not only requires a reasonable route design according to the overall layout of the area but also needs roadway illumination to facilitate people's travel at night. LED streetlights are crucial devices for road lighting projects. The quality of streetlights should be a key consideration in equipment purchases. Poor-quality streetlights require frequent maintenance and replacement. This not only affects the safety of passersby but also increases the burden of public expenditure on urban construction.

Common LED Street Light Problems Stem from Cost-Cutting Manufacturers

The root of the problem is the insufficiency of innovation.

To gain market share, many manufacturers lower the cost through the sacrifice of materials and processes to attract more streetlight wholesalers. This has a major impact on the quality of LED streetlights. Street lighting projects require a lot of high-quality LED streetlights to illuminate all kinds of roads in the city, ensuring that all nighttime activities can proceed normally. In reality, LED street lamps vary in price and quality, and even the most careful selection will find itself facing these common problems.

That said, it's imperative to understand these problems and pay extra close attention. Without this attention, consumers may be tricked into buying fake products.

8 Common Problems Regarding LED Street Lights

1. Exaggerated product parameters

Occasionally, manufacturers resort to exaggerated product parameters to catch the eyes of consumers and position their products in the market. However, in most cases, the reduced configuration is not enough to support the required lighting efficacy. Buyers naturally shop around for a better deal, but this trend can lead to unhealthy competition between sellers. The market becomes filled with tricks, making it difficult to select the most cost-effective road lamp from a wide range of products.

2. Using counterfeit imported chips and driving powers

The core components of LED street lights are the chips and the driving powers, which directly determine the performance of the lights. Some unscrupulous businessmen may use counterfeit imported chips and driving powers to assemble their products and sell them at the same price as genuine branded products. This results in financial loss for customers and product quality defects.

3. Substituting copper wires for gold wires in LEDs

Many LED manufacturers secretly substitute inferior goods for superior ones. It is generally known that the chemical stability of gold wires in LEDs is better than that of copper alloy wires, gold-coated silver alloy wires, silver alloy wires, etc.

Although these alternatives are superior to gold wire in some properties, they are not as excellent as gold wire in terms of LED properties. These alternative wires are much less stable in terms of chemical stability. For example, silver alloy wires and gold-coated silver alloy wires are prone to corrosion by sulfur/chlorine/bromine, while copper wire is prone to oxidation and vulcanization.

When using these alternatives in LEDs, the LEDs become more vulnerable to chemical corrosion, reducing the reliability of light sources and making LED beads easily fail due to broken wires after some time of use.

4. Unreasonable light distribution design and poor penetrability lens

The lighting effect is closely correlated with the light distribution design in terms of optical design. If the light distribution is not designed reasonably, the illumination effect will not be optimal. Manufacturers can observe these effects during early testing. However, buyers may overlook this aspect and lack access to such information. In the complex market, information asymmetry poses a bigger threat to wholesalers, and the shopping trap driven by a lack of technological cognition is also a major concern.

5. Poor heat dissipation design

The service life of semiconductor devices is reduced significantly with every 10 ℃ increase in the junction temperature of the LED chip. Due to the high brightness requirements of LED street lamps and the harsh usage environment, LED street lights require effective heat dissipation. If heat dissipation is poorly resolved, it will lead to quicker aging of LEDs and reduced stability.

6. Driving power failure

Many people overlook the importance of driving power for LED street lights. However, driving power failures can lead to various issues such as the light not working, some LEDs failing, the lamp blinking, parts getting damaged, and more.

7. Security issues of LED streetlights

Safety issues also deserve serious attention. For instance, it is important to consider whether the driving power of a road lamp has leakage protection:

• If there is a guarantee of the quality of street lamp ballasts;
• If the sensitivity of the breaker has been checked;
• If the selected current range for the trip is too large;
• If the waterproof rating meets the requirements of outdoor lighting;
• If there is any lightning protector.

These factors are involved in the security issues of street lights and need to be understood. These circumstances may lead to a short circuit caused by excessive current during thunderstorm weather, resulting in lighting failure.

8. Harmful materials that affect the lifespan of LEDs

LED blackening is a common problem encountered by lighting companies. Most materials in lighting fixtures need troubleshooting to assess their impact on LED service life.
