3-Year Warranty but 10-Year Utilization? Why Lifud LED Drivers are so “Unremitting”?
Lifud 3-year warranty LED driver can be used for 10 years? Are you curious about it? Read the following text!
We have already shared two cases about the utilization of our LED drivers, including the LED drivers that have been used for 5 years in the factory of Dongfeng Nissan and the LED drivers for street lighting that have been used for 7 years at the wharf. Now we collect another case about 10-year utilization of our LED drivers for commercial lighting.
The LED driver mentioned in the following chat records is LF-G418B series. Customers who knew Lifud can get some information from driver’s name that it is Lifud’s early external LED driver for tube light and panel light and the warranty of this series is 3 years.
Why a 3-year warranty LED driver can be used for 10 years?
This series of LED driver is applied in the tube light and the temperature and humidity conditions are basically within the scope of our company’s environmental requirements. Certainly, the light with this LED driver is lighted up during normal working hours every day. From the above information, we can see that it is normal that this LED driver of Lifud can be used for 10 years.
Now we are going to explain the utilization conditions of Lifud LED driver’s warranty. Taking this LED driver as an example, If a 3-year warranty LED driver wants to work for 3 years, it has to meet the following two conditions:
- The LED driver is properly applied in its working environment (according to the guidance of Lifud LED driver specification)
- The LED driver works continuously for 24 hours a day and 365 days a year (according to the guidance of Lifud LED driver specification)
Then the working life of LF-G418B series :
24H/day*365 days/year*3 years =26280H
The actual work hours is 8H a day, and the lifetime is:
26280H÷8H/day÷365 days/year=9 years
That is to say, if the LED driver works for 8H a day, a 3-year warranty driver can be basically used for 9 years. If the rest days are removed, presumably we will understand why Lifud LF-G418B series can be used for 10 years.
Some readers may have noticed a sentence “The LED driver is properly applied in its working environment according to the guidance of Lifud LED driver specification.” Take the lifetime curve of an LED driver as an example, it is obvious that the lifetime of the LED driver varies greatly under different casing temperatures. Thus the warranty lifetime of electronic products will have some requirements on the ambient temperature and the casing temperature.
Take the LED driver for track light that is most likely to be improperly used for example. Generally, the LED driver for track light is built in the light cavity or the track box that requires higher temperature resistance. Besides, due to the heat from lamp beads and the space inside the light cavity, the LED driver built in the light cavity is required more than in the track box. Thus, if the LED driver used for non track light is applied in the track light, the lifetime of the LED driver will be reduced or even the LED driver will be damaged because some components are not suitable for the high temperature environment inside the track light.
The installation method of the LED driver for track light
In terms of this kind of issue, Lifud developed the corresponding LED driver, such as Lifud new hot-sale built-in LED driver LF-GIFxxxYFII series that uses high temperature resistance components and has special heat dissipation structure, which enables the LED driver available in Ta (ambient temperature) 55℃. Besides, this series of LED driver has excellent electrical performance parameters and small volume.
LF-GIFxxxYF II series
As for the LED driver built in the light cavity, Lifud developed a classical and high-end LED driver for track light LF-GICxxxYS series with the semi-glue design for strengthening the heat dissipation, which makes the LED driver available in the Ta (ambient temperature) 60℃.
Now is it clear that why a 3-year warranty LED driver of Lifud can be used for 10 years?
