The invention relates to a light-emitting diode fixing seat, in particular to a light-emitting diode fixing seat for fixing an LED on a circuit board in an LED lamp structure.

As shown in FIG. 1 and FIG. 2, a general LED lamp 1 includes a reflector 11 having a plurality of lamp holes 111, a circuit board 12 locked to the reflector 11, and most of the lamps are respectively disposed on the lamp. The light-emitting diodes 13 of the circuit board 12 are electrically connected to the holes 111.

Each of the LEDs 13 has a light-emitting portion 131 that is inserted into the corresponding lamp hole 111, and two pins 132 that are electrically connected to the light-emitting portion 131. The two pins 132 are respectively inserted through the circuit. The second plate 12 has a hole 121 and is soldered to one of the bottom surfaces of the circuit board 12. Due to the viewing angle, only one of the pins 132 of the LED 13 and one of the reserved holes 121 of the circuit board 12 are shown.

In the assembly process of the LED lamp 1, the reflector 11 is first locked with the circuit board 12, and the LED 13 is fixed in the lamp hole 111, and then the light is emitted. The pin 132 of the pole body 13 is inserted through the reserved hole 121 and soldered to the bottom surface of the circuit board 12, and the assembly of the reflector 11, the LED 13 and the circuit board 12 is completed.

However, since the LEDs 13 are first fixed on the reflector 11, and then aligned and soldered to the circuit board 12, the pins 132 of the LEDs 13 are less easily inserted into the reflector. In the reserved hole 121 of the circuit board 12, in particular, as the three-dimensional structure of the reflector 11 tends to be free and irregular, the assembly difficulty between the LED 13 and the circuit board 12 is relatively improved. . Moreover, the light-emitting portion 131 of the light-emitting diode 13 is simply supported and positioned by its pins 132. During the running of the vehicle, vibration and shaking are easily generated, which not only affects the safety lighting effect, but also may cause the pins 132 to be loose. The light is removed so that the light-emitting diode 13 is damaged.

Accordingly, it is an object of the present invention to provide a light-emitting diode mount that can be quickly, accurately, and stably assembled on a circuit board in an LED lamp structure.

Therefore, the LED assembly of the present invention is used for fixing a light-emitting diode to a circuit board, the light-emitting diode has a light-emitting portion, and two pins electrically connecting the light-emitting portions, each of which A bottom portion of the pin is inserted through and fixed to a bottom surface of the circuit board; the LED mounting seat includes a supporting surface that is attached to a bottom surface of the light emitting portion, and a top surface of the circuit board is connected a connecting surface, and two concave surfaces; the two side concave surfaces are opposite to each other, each side concave surface extends from the supporting surface to the connecting surface, and defines one of the pin plugs for the light emitting diode The positioned undercut groove has an abutment surface for the pin to abut against an opening of the undercut groove.

The effect of the invention is that the light-emitting portion of the light-emitting diode can be stably seated on the support surface, and the two pins of the light-emitting diode can be inserted and restrained in the two-side groove and closely adhered By the two abutting the face, the light-emitting diode can be quickly, accurately and stably positioned on the circuit board.
