[0007] As a further solution of the utility model, the PCBA module is fixedly connected to the bottom of the inner cavity of the aluminum strip through multiple groups of plastic rivets.
[0008] As a further solution of the present invention, the lampshade is made of PC material.
[0009] As a further solution of the utility model, a group of mounting holes are respectively provided at both ends of the aluminum bar, and the mounting holes are used to install positioning screws.
[0010] As a further solution of the utility model, a shock-absorbing gasket is installed on the positioning screw.
[0011] Compared with the prior art, the utility model replaces the transmission installation frame by designing a U-shaped structural aluminum bar, and the PCBA module is inserted and fixed on the aluminum bar. The PCBA module is provided with multiple groups of quick-connect terminals, which are quickly connected to the power supply lines of the power module through the multiple groups of quick-connect terminals. At the same time, the controller is a DALI control system, which solves the problems of the existing U-shaped lamps with complex structures, which are often formed by stamping and splicing, are difficult to install and have high costs, and cannot be quickly wired, causing difficulties for installers.
