Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a composite substrate that facilitates wire bonding. Background Technology

[0002] Existing track lights generally use external power supplies, which have many wires and cannot be placed on the same base plate as the light source. Because wires need to be installed to connect to the base plate inside the lamp tube where the light source is installed, and the cable contains several wires, the space inside the lamp tube is very limited, and several wires need to be soldered to the base plate, so it is not possible to run the wires from the side.

[0003] Therefore, the existing wire bonding method involves passing the end of the line through the outside of the substrate and then bending it at a large angle so that the end of the line can be soldered to the light-emitting side of the substrate. This method involves bending the end of the line at too large an angle, which is inconvenient for soldering. Therefore, this application proposes a composite substrate that facilitates wire bonding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a composite substrate that facilitates wire bonding. It solves the problem that existing wire bonding methods involve passing the end of the wire through the outside of the substrate and then bending it at a large angle so that the end of the wire can be soldered to the light-emitting side of the substrate. However, this method results in an excessively large bending angle at the end of the wire, making soldering inconvenient.

[0008] When connecting the wire to the wire bonding hole, the wire is routed on the outside of the aluminum substrate and the end of the wire passes through the wire bonding hole for welding.

[0009] Furthermore, a through hole is provided at the geometric center of the fiberglass board, and the size of the light source is adapted to the through hole.

[0010] Furthermore, the bottom surface of the fiberglass board is provided with a mounting frame, and the aluminum substrate is embedded in the mounting frame.

[0011] Furthermore, a positioning block is installed on the inner ring surface of the mounting bracket, a positioning groove is opened on the outer side of the aluminum substrate, and the positioning block is embedded in the positioning groove.

[0012] Furthermore, the mounting bracket has a through-hole for wire threading, and the wire is installed by passing through the through-hole.

[0013] Furthermore, the fiberglass board has a through first mounting hole, and the mounting bracket has a through second mounting hole.

[0014] Furthermore, the first mounting hole is connected to the second mounting hole, and the bolt can be connected to the track light tube after passing through the first mounting hole and the second mounting hole.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This application provides a convenient composite substrate for wire bonding, solving the problem of existing wire bonding methods that require the wire end to pass through the outside of the substrate and bend at a large angle to solder the wire end to the light-emitting side of the substrate.
