Problems solved by technology

In this patent application, the LED chip and the control IC board are integrated and packaged as a whole, and the installation is simple and convenient. However, since each LED chip and the control IC are fixed on the control IC board, since the control IC board needs to occupy a certain volume, therefore, The structure is still not compact enough, and the overall volume is relatively large
