    What does the service life of high power 200w outdoor slim led floodlight depend on? How do you judge the long life of high power 200w outdoor slim led floodlight? In order to avoid frequent replacement, people choose lamps with a long service life, but when judging the service life of lamps, there are no certain rules to find, and they can only be judged by experience.
    The first is to see if the protection level of the cavity protecting the LED lamp beads is high enough; whether the chip junction temperature is within the designed safe range and the quality of the LED lamp beads used. As for the power supply, it depends on whether there is enough margin in its design to ensure the life of more than 50,000 hours.
    
    Of course, you can also comprehensively judge its authenticity through the national-level testing agency or recognized test report provided by the enterprise, the proof of selection of key components, the theoretical basis of the life of the high power 200w outdoor slim led floodlight lamps, and the credibility of the enterprise . Among them, the LM80 report of LED lamp beads and the authoritative lamp temperature (including pins) report can be calculated based on the values ​​in it.
    
    You can also judge the life of high power 200w outdoor slim led floodlight lamps according to the light decay curve of high power 200w outdoor slim led floodlight lamps. Under actual outdoor lighting conditions, the light decay of different high power 200w outdoor slim led floodlight does not show regularity. , Different types of lamps have different light decay curves. Simply predicting the life of the luminaire with the change of the light decay curve, the reliability and confidence rate are low. In addition, the design of the sealing structure of the lamp, the selection of the sealing material, and the selection of the optical protective material will 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 luminaire, the reliability of high power 200w outdoor slim led floodlight luminaires can be greatly improved through reasonable power cavity temperature design and the addition of lightning and anti-surge protectors.
