As a key component in LED lighting, the quality of the LED driver directly affects the reliability and stability of the overall. Based on LED driver and other related technologies and customer application experience, we analyzes the failures of lamp design and application:
1. The following conditions that often occur can cause damage to the LED driver:
✔ The AC is connected to the DC output of the driver, causing the drive to fail;
✔ The AC is connected to the input or output of the DC/DC driver, causing the drive to fail;
✔ The constant current output terminal is connected with the modulating light, causing the driver to fail;
✔ The phase line is connected to the ground line, resulting in no output of the driver and charging of the outer casing;
2. The Line Frequently Trips
The lights on the same branch are connected too much, resulting in overloading of the load on one phase and uneven distribution of power between the phases, causing the line to trip frequently.
3. Cooling Problem
When the drive is installed in a non-ventilated environment, the drive housing should be in contact with the lamp housing as much as possible. If possible, apply thermal grease or thermal pad on the contact surface of the housing and the lamp housing to improve the heat dissipation performance of the driver, thus ensuring the driver’s life and reliability.
In summary, the LED driver has many details to be aware of in practical applications. Many problems need to be analyzed and adjusted in advance to avoid unnecessary failures and losses!
