With the development of lighting technology, LED is used more and more widely, and led driver has also been paid attention to as a part of it. The LED will fail after the warranty period, and it may be necessary to buy a new lamp or replace the led driver. Under most cirumstances, you only need to replace the Led driver.
What information do I need to know when replacing the led driver?
1) Do you need a constant voltage led driver or a constant current led driver? Constant voltage led drivers are usually used for led strips, cabinet lights, sign lighting, etc. If you are still not sure, remember that the output voltage of the constant voltage led driver is a fixed value, usually 5V, 12V, 24V, 36V, 48V. The output voltage of the constant current led driver is a range, such as 54-80V. Constant current led driver is usually used for panel lights, ceiling lights, downlights and other lamps.

2) The specific parameters of the Led driver. Usually need to know these three parameters: power, output voltage, output current, in order to find the exact same led driver. At the same time, it is also necessary to know the input voltage. The input voltage of the led driver is usually 180-265Vac or 85-265Vac. In addition, it is necessary to ensure that the current variation of the led driver does not exceed ±5. If the variation range exceeds this value, there is a difference in the brightness of the lamp.
3) Determine the external environment of the installation location of the led driver. If the led driver is used in street lamps, garden lamps and other outdoor lamps, it needs waterproof performance - IP65, IP67. For indoor lighting, you can choose a non-waterproof led driver.
4) Is there a dimming requirement? The dimming methods of Led driver include Triac dimming, 0-10V dimming, PWM dimming, Dali dimming, etc. Dimmable led drivers can also be used on non-dimmable lamps, but the cost will be higher.
5) Consider the size of the led driver. When the led driver is placed inside the lamp, such as Bulb light, tube light., try to choose a small size led driver, so as to fit the led driver into a limited space.
If you can try to take a picture of the led driver label and a picture of the lamp, it will make it easier for you to purchase led drivers.
After confirming this information, you can purchase the corresponding led driver and install it.
