In principle, after LED lamps are assembled into finished products, they need to be tested for aging. The main purpose is to see whether the LED is damaged during the assembly process and to check whether the power supply is stable in a high temperature environment. In fact, a short aging time has no evaluation value for the light effect. Aging tests are flexible in actual operation, which can not only meet the requirements of relevant standards, but also improve production efficiency. Today, LED lamp manufacturer TIANXIANG will show you how to do it.
To test the aging standards of LED lamps, it is necessary to use two major testing tools, power test boxes and aging test racks. The test is carried out under normal temperature, and the time is usually set between 6 and 12 hours to ensure the performance of LED lamps in different time periods. During the test process, pay attention to key indicators such as lamp temperature, output voltage, power factor, input voltage, input current, power consumption, and output current. Through these data, you can fully understand the changes of LED lamps during the aging process.
Lamp temperature is one of the important indicators for testing the aging of LED lamps. As the use time of LED lamps increases, the internal heat gradually accumulates, which may cause the temperature to rise. In the aging test, recording the temperature changes of lamps in different time periods helps to judge the thermal stability of LED lamps. If the temperature rises abnormally, it may be that the internal heat dissipation performance of the LED lamp is poor, indicating that the aging speed is accelerated.
Output voltage is a key indicator for measuring the performance of LED lamps. During the aging test, continuously monitoring the fluctuation of the output voltage can help determine the voltage stability of the LED lamp. A decrease in output voltage may indicate that the luminous efficiency of the LED lamp has decreased, which is a normal manifestation of the aging process. However, if the output voltage suddenly fluctuates or drops sharply, it may be that the LED lamp has failed and further investigation is needed.
Power factor is an important indicator for measuring the power conversion efficiency of LED lamps. In the aging test, by comparing the ratio of input power to output power, it can be determined whether the energy efficiency of the LED lamp remains stable. A decrease in power factor may indicate that the energy efficiency of the LED lamp has decreased during the aging process, which is a natural phenomenon of the aging process. However, if the power factor decreases abnormally, it may be that there is a problem with the internal components of the LED lamp, which needs to be dealt with in time.
Input voltage and input current are equally important in aging tests. They can reflect the current distribution of the LED lamp under different working conditions. By recording the changes in input voltage and input current, the working stability of the LED lamp can be determined. Fluctuations in input voltage or abnormal distribution of input current may indicate performance problems of LED lamps during the aging process.
Power consumption and output current are key indicators for measuring the actual performance of LED lamps. In the aging test, monitoring the power consumption and output current of LED lamps can determine whether their luminous efficiency remains stable. Rising power consumption or abnormal fluctuations in output current may indicate that the LED lamp is aging faster, and attention should be paid to its performance changes.
LED lamp manufacturer TIANXIANG believes that by comprehensively analyzing the data provided by the power test box and the aging test rack, a comprehensive understanding of the performance of LED lamps during the aging process can be obtained. Paying attention to key indicators such as lamp temperature, output voltage, power factor, input voltage, input current, power consumption, and output current can help determine the aging speed and performance stability of LED lamps, so as to take corresponding maintenance measures to ensure the long-term and reliable use of LED lamps.
