Now the LED injection molding module has been widely used, whether it is the street or the light box light source of the station and wharf, the LED injection molding module is a good choice. Let's discuss it together.
Everyone knows that the most common way to improve the drive power efficiency of LED injection modules is to optimize the design of electronic transformer parameters to reduce eddy current losses caused by ringing. But besides this, are there any other related techniques? I would like to share with you 5 techniques to improve the efficiency of driving power supply for LED injection molding modules, hoping to help you.
1. The main current loop PCB should be as short as possible. LAYPCB's experience, and layout, this is nothing, the quick way is to look at the works of big manufacturers.
2. Optimize the transformer parameter design to reduce the eddy current loss caused by ringing. This is more difficult. First, you must master the basic knowledge of electromagnetics, design a reasonable transformer, and the most important thing is patience. Even if you think of improving the efficiency by 0.5%, you should try it.
3. If the optimal design of the input EMI part exceeds the safety regulations, this part is more elegant, mainly because of experience.
4. Many people ignore this when choosing a good electrolytic capacitor, and the loss of electrolysis is very large.
5. On the premise that the power consumption of the startup part is designed to be efficient, it must be considered. At present, many chips have HV startup pins, and the startup current is getting lower and lower. This point is to know more about new devices.
