The fogging of bi-led fog light lampshade is a common phenomenon in actual use. There may be many reasons behind it. It is necessary to analyze and take corresponding treatment measures according to the specific situation. First of all, it is necessary to clarify the degree and state of fogging. There is an essential difference between slight fogging and severe water accumulation, and the treatment methods are also very different. Slight fogging usually manifests as a thin layer of water mist attached to the inner wall of the lampshade, which appears when the ambient temperature changes. This situation may be caused by high air humidity or temperature difference, while severe water accumulation may mean that there is a problem with the sealing of the lampshade, which requires more in-depth investigation. Therefore, the first step is to carefully observe the condition inside the lampshade, judge the nature of the fogging, and provide a basis for subsequent treatment.
For slight fogging caused by high ambient humidity or temperature difference, there is generally no need to worry too much. This is a normal physical phenomenon. During the driving process of the vehicle, the LED fog lamp will generate a certain amount of heat when working, which can accelerate the evaporation and dissipation of the fog. At this time, you can choose to turn on the fog lamp when the weather is clear, let the light continue to shine for a period of time, and use the heat generated to increase the temperature inside the lampshade, so as to promote the gradual evaporation of the fog. At the same time, you can also turn on the vehicle's air conditioning system and use the hot air mode to blow toward the outside of the lampshade. By increasing the external ambient temperature, the temperature difference between the inside and outside can be reduced to help the fog dissipate faster. It should be noted that before the fog has completely dissipated, the fog lights should be turned on and off frequently to avoid aggravating the fogging phenomenon due to repeated temperature changes.
If the lampshade fogs frequently or lasts for a long time, you may need to check whether there is a problem with the sealing of the lampshade. There is usually a rubber seal or sealing strip at the junction of the lampshade and the lamp body. After long-term use, it may age, deform or crack, causing external moisture to enter the inside of the lampshade. At this time, you need to carefully check the sealing part. If you find that the sealing ring is aged and hardened, loses elasticity, or the sealing strip is detached or damaged, it should be replaced in time. When replacing, you need to choose a sealing accessory that matches the original car model to ensure that it is installed in place to avoid new sealing problems due to size mismatch or improper installation. Before installing a new seal or strip, you can apply a small amount of sealant to the joint to enhance the sealing effect and further prevent moisture intrusion.
If there is obvious water accumulation inside the lampshade, it means that the sealing problem is already serious and must be dealt with in time, otherwise it may affect the service life of the LED lamp beads and even cause a short circuit fault. First, the fog lamp assembly needs to be removed from the vehicle, and be careful to avoid damaging the circuit and other components during the disassembly process. After disassembly, separate the lampshade from the lamp body, pour out the accumulated water inside, and wipe the inner wall of the lampshade and the surface of the lamp body with a clean soft cloth or paper towel to ensure that there is no residual water. Then check whether the lampshade has cracks or damage. If there are slight cracks, you can use a special plastic welding tool to repair it; if the cracks are large or the lampshade is seriously damaged, you need to replace it with a new lampshade. After the treatment is completed, reinstall the fog lamp assembly in the correct order, and carefully check the sealing of each connection part to ensure that the installation is firm and the sealing is good.
In daily use, good maintenance of the bi-led fog light can effectively prevent the occurrence of fogging problems in the lampshade. First of all, avoid using a high-pressure water gun to directly rinse the surface of the lampshade when washing the car, especially the sealing part. The high-pressure water flow may break through the sealing ring and cause moisture to enter. When washing the car, you should use low-pressure water or a soft cloth to gently wipe the lampshade to clean the dust and dirt on the surface. Secondly, check the sealing condition of the fog lamp regularly, especially after the vehicle has been driving on bumpy roads or in bad weather for a long time, and check whether the lampshade is loose, deformed or sealed. In addition, keeping the engine compartment of the vehicle well ventilated to avoid moisture accumulation in the compartment will also help reduce the possibility of fogging of the fog lampshade.
If the vehicle is still within the warranty period, when the bi-led fog light lampshade is found to be fogging, it is recommended to contact the dealer or manufacturer in time for processing. Professional after-sales personnel can judge the nature of the problem according to the specific situation. If it is a product quality problem, such as imperfect sealing process at the factory, free repair or replacement service is usually provided. When communicating with after-sales, the phenomenon of fogging, frequency of occurrence, environmental conditions and other information should be described in detail so that the staff can more accurately judge the cause of the fault and take corresponding measures. It should be noted that sealing damage caused by human factors, such as collision, unauthorized disassembly and modification, may not be covered by the warranty. Therefore, the operating procedures should be followed during use to avoid unnecessary human damage.
From a preventive perspective, choosing bi-led fog light products with reliable quality is the key to reducing subsequent problems. When purchasing, you should pay attention to the sealing performance of the product and check whether there is a professional waterproof certification, such as IP67, to ensure that the lampshade has good sealing during the design and manufacturing process. At the same time, you should choose regular sales channels to purchase and avoid buying counterfeit and shoddy products. These products often have defects in materials and workmanship, and are prone to problems such as poor sealing. During installation, you should ensure that the fog lamp assembly is installed in place, and all fixing screws and sealing components are well tightened. If necessary, additional waterproof treatment can be performed on the sealing parts during the installation process, such as applying sealant, etc., to improve the waterproof performance of the fog lamp from the source and reduce the risk of fogging of the lampshade. Through the above multi-faceted treatment and preventive measures, the problem of fogging of the bi-led fog light lampshade can be effectively solved to ensure the normal use of the fog lamp and driving safety.
