LED panel lights are widely used and have a trend of replacing grille lights; LED panel lights are mainly used in:
1. Ceiling (instead of the original grille light);
2. Walls (not only for lighting purposes, but also for artistic embodiment);
3. Installation body (the pursuit of practical and artistic combination, convenient and simple installation);
4. Others (can also be used in other places, such as train boxes or large mobile cars, counters, etc.);
