Walking on the street, whether it is hotels, restaurants, shopping malls, gas stations, airports, railway stations, subway stations, etc., light box advertisements can be seen everywhere. Lightbox advertisements have become an important means for Chinese and foreign enterprises and institutions to promote their images and display their brands, and frequently appear in various public places. It is a good choice to choose LED injection molding module as the light source of the light box. How to improve the drive power efficiency of LED injection molding module? Let's discuss it together today.

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. The optimal design of the input EMI part is more sophisticated, mainly based on experience.

4. Choose a good electrolytic capacitor, many people ignore this, 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.
