When we buy LED high bay lights, sometimes it is because the LED high bay lights indicate that the lamp has a service life of at least 100,000 hours. In order to avoid frequent replacement of lamps and save costs, choosing LED high bay lamps to replace other lamps is an inevitable development of manufacturers. However, the service life of some LED high bay lights is far from the 100,000 hours stated above. What is the reason? Does it indicate that the above is false?

　　 In fact, many consumers have encountered this problem. In fact, the service life of LED lamps is more than 100,000 hours, which is in an ideal state, but in real space, due to various factors, it is impossible to reach 100,000 hours.

　　The environment and the heat dissipation design of the lamp will affect the service life of the lamp. For example, heat dissipation design; why can't LED lamps reach the height of incandescent lamps? One of the reasons is because of the cost; another important reason is that the heat dissipation design of the lamps has not made a big breakthrough, and the heat dissipation design limits the popularization of LED lamps.

　　 If the heat dissipation design of the lamp is not done well, it will seriously affect the service life of the lamp, greatly reduce the use function of the lamp, and cause premature light decay.

The LED high bay light will generate heat during use, and will generate a lot of heat. If the heat dissipation design is not done well, the heat cannot be dissipated. If it accumulates in small LED lamps, it will damage the components in the lamp for a long time. The service life of the lamp is impaired. Moreover, in our country, the LED lighting market is not very standardized. Many LED lighting manufacturers with insufficient strength have reduced various data on the LED lighting products, which are inferior products. Therefore, when many consumers buy LED high bay lights, the service life of LED high bay lights does not meet the instructions.

How to judge the life span of LED street lights?

　　 What does the service life of LED street lights depend on? How to judge the long service life of LED street lights? When people choose lamps and lanterns, in order to avoid frequent replacement, they will choose lamps with a longer service life. However, when judging the service life of lamps, there is no certain rule to be found, and they can only be judged more empirically.

　　 First of all, it is to see whether the protection level of the cavity that protects the LED lamp bead is high enough; whether the junction temperature of the chip is within the designed safe range and the quality of the LED lamp bead used. As for the power supply, it depends on whether the design has enough margin to ensure the life span of more than 50,000 hours.

　　Of course, the authenticity of the LED street lamp can be judged comprehensively through the national test agency or approved test report provided by the company, the proof of the selection of key components, the theoretical basis of the life of the LED street lamp and the relevant data and the credibility of the company. Among them, the LM80 report of the LED lamp beads and the authoritative lamp temperature (including pins) report can be calculated based on the values.

The life of LED street lamps can also be judged according to the luminous decay curve of LED street lamps. In the actual outdoor lighting situation, the luminous decay of different LED floodlights does not show regularity, and the luminous decay curves of different lamp types are different. Simply using the change of the light decay curve to predict the life of the lamp has low reliability and confidence. In addition, the design of the sealing structure of the lamp, the selection of sealing materials, and the selection of optical protection materials will all have a direct impact on the reliability and light attenuation of the lamp. Although the power supply is the most easily damaged part of the lamp, the reliability of the LED street lamp can be greatly improved through the reasonable temperature design of the power supply cavity and the addition of lightning and surge protectors.
