Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.
As shown in FIG. 1, a door handle backlight unit, including PCB base plate 1 and printing opacity colloid 2, the integration has LED on PCB base plate 1, printing opacity colloid 2's encapsulation just with PCB base plate 1 fixed connection on LED. The LED is integrated on the PCB substrate 1 to form an LED chip assembly, the LED is packaged by the light-transmitting colloid 2 and is integrally formed by adopting a forming process, the shape of the light-transmitting colloid 2 can meet the requirements of different design schemes, a lens is not required to be additionally configured, the assembling link is reduced, and the assembling cost of the vehicle door handle can be effectively reduced.
The light-transmitting colloid 2 is cylindrical, a light-emitting inclined plane 21 is formed at the upper end of the light-transmitting colloid 2, the light-emitting inclined plane 21 is used for meeting the design requirement of the arc-shaped surface of the vehicle door handle, and further, the light-emitting inclined plane 21 can also adopt a curved surface structure.
The lower extreme of printing opacity colloid 2 is equipped with pier stud 22, and the lower extreme and the shaping of PCB base plate 1 of pier stud 22 are connected, and the transversal personally submits of pier stud 22 is circular and be equipped with discernment tangent plane 23 on one side outer fringe of pier stud 22. The diameter of pier stud 22 is greater than the diameter of printing opacity colloid 2, and pier stud 22 can promote LED's stability as LED's main packaging structure. Further, the identification land 23 corresponds to the polarity of the LED for ease of inspection use.
One end of the PCB substrate 1 is provided with a fool-proof flange 11, the fool-proof flange 11 is used for identifying the polarity of the LED when the PCB substrate 1 is assembled and welded, and particularly, the PCB substrate 1 forms a distinguishing configuration of a left door handle and a right door handle through the fool-proof flange 11.
Two electrode pads 12 are arranged at the other end of the PCB substrate 1, and the two electrode pads 12 are arranged at intervals. The electrode pad 12 is used for being welded on a control circuit, one end of the PCB substrate 1 is provided with a positioning hole 13, and the positioning hole 13 is used for positioning the PCB substrate 1 on a door handle so as to improve the assembly efficiency.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
