Why LED Lights and lamps sometimes get recalled

In recent years, developed countries in Europe and America have recalled dozens of LED Lights and lamps in China each year. After analysis, there are four major quality issues:

The first is that the product's waterproof performance is not up to standard, and it is prone to moisture, resulting in damage to the interior of the lamp. Such products mainly appear in outdoor LED lamps; second, the products are not protected against electric shock and do not meet the standard requirements, mainly due to defects in the design of some manufacturers. There is potential for electric shock, and poor insulation of the cable may also cause fire. Third, there are quality risks in the internal wiring and external wiring of the product, which may easily lead to dangers such as electric shock, fire, falling and bruising, and endanger the personal and property safety of consumers; Fourth, toxic and hazardous substances are contained in products, which do not meet the requirements of relevant foreign laws and regulations.
How to protect the life of LED lights? When selecting the LED driving power, it is necessary to fully consider the reliability, efficiency, driving mode, and protection function of the power supply. LED is an energy-saving product, and the efficiency of driving power is high. The structure of the power supply installed in the lamp is particularly important. Because the LED's luminous efficiency decreases as the LED temperature increases, the heat dissipation of the LED is very important. The efficiency of the power supply is high, its power consumption is small, and the heat generation in the lamp is small, which also reduces the temperature rise of the lamp, which is beneficial to delaying the light failure of the LED.
