First of all, we need to analyze the root cause of LED driver quality problems?
First, non-professional LED power supply manufacturers have limited design and manufacturing capabilities (requirements are too scattered and quantities are too small);
The second is that the LED lamps are not designed according to the harsh working environment.
01)-35 degrees to 70 degrees ambient temperature
02) Solve the problem of insufficient waterproof design.
03) Solve the problem of inadequate lightning protection design.
Secondly, how can we ensure the quality and reliability of the LED driver through design and demonstration?
01) Standardized professional design process control Technical preliminary research, feasibility assessment, preliminary design, detailed design, engineering prototype, and small batch trial production.
02) Reasonable component design margin
03) Selection of high-quality components Electrolytic capacitors, ICs, power semiconductors, magnetic components, etc.
04) Strict quality verification and testing procedures Stress analysis, EVT, SVT, DVT and other tests and calculation and experimental verification of MTBF.
