[0006] As a further solution of the utility model, the fixing piece is a plastic rivet, and mounting holes for inserting the plastic rivets are provided on both ends of the PCBA module and on the side panels corresponding to the aluminum strip.

[0007] As a further solution of the present invention, the lampshade is made of PC material.

[0008] 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, and shock-absorbing gaskets are installed on the positioning screws.

[0009] Compared with the prior art, the utility model replaces the transmission installation frame by designing an L-shaped aluminum bar, and the PCBA module is inserted and fixed on the aluminum bar, thereby solving the problems of the existing U-shaped lamps that are complex in structure, often formed by stamping and splicing, difficult to install and high in cost. At the same time, 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 problem that the existing lamps cannot be quickly wired during installation, causing difficulties for installers.

[0014] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, an L-shaped line lamp for a vehicle comprises an aluminum bar 1, which is an L-shaped structure, on one side of which a PCBA module 3 is insertedly installed through a fixing member, on which a plurality of groups of LED light sources 301 are sequentially arranged at intervals, a lampshade 2 is fixed on the PCBA module 3, a power module 6 is fixed at one end of the aluminum bar 1, a plurality of groups of quick-connect terminals 302 are arranged on the PCBA module 3, the power module 6 is electrically connected to the quick-connect terminals 302 on the end side of the PCBA module 3 through a power supply line 601, the power module 6 is electrically connected to a controller 4 through a signal wire 401, and the controller 4 is a DALI control system;

[0016] Furthermore, in the present invention, the weight of the device is greatly reduced by replacing the traditional installation frame with an aluminum bar 1. At the same time, the quick-connect terminal 302 at the end of the PCBA module 3 can realize the quick connection of the power supply line 601, which greatly improves the work efficiency of the installer.

[0017] like Figure 2 and Figure 3As shown, in the embodiment of the utility model, the fixing part is a plastic rivet 5, and mounting holes for inserting the plastic rivets 5 are provided on the two ends of the PCBA module 3 and the corresponding side panels of the aluminum strip 1. When installing the PCBA module 3, multiple groups of plastic rivets 5 are inserted into the mounting holes of the side panels on one side of the aluminum strip 1, and the plastic rivets 5 clamp the mounting holes to fix the PCBA module 3.

[0018] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the lampshade 2 is made of PC material;

[0019] Furthermore, the utility model provides a group of mounting holes at both ends of the aluminum bar 1 , respectively. The mounting holes are used to install positioning screws, and shock-absorbing washers are installed on the positioning screws. The shock-absorbing washers can reduce the wear of the aluminum bar 1 on the mounting surface.

[0020] In summary, the utility model designs an L-shaped aluminum bar 1 to replace the transmission installation frame, and the PCBA module 3 is inserted and fixed on the aluminum bar 1, so as to solve the problems of the existing U-shaped lamps with complex structures, which are often formed by stamping and splicing, difficult to install and high cost. At the same time, the PCBA module 3 is provided with multiple groups of quick-connect terminals 302, which are quickly connected to the power supply line 601 of the power module 6 through the multiple groups of quick-connect terminals 302. At the same time, the controller 4 is a DALI control system, which solves the problem that the existing lamps cannot be quickly wired during installation, causing difficulties for installers.

[0021] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
