Abstract
The utility model discloses a fixed structure of a light emitting diode, which comprises a diode light emitting piece and a shell body, wherein the shell body is sealed at the head part of the diode light emitting piece. A terminal pin of the diode light emitting piece is welded on a circuit board, and the bottom of the shell body is provided with a supporting pin in a downward extended mode. The supporting pin is abutted on the circuit board, a positioning hole is arranged on the circuit board, and the supporting pin is abutted in the positioning hole. The fixed structure of the light emitting diode has simple structure and good effect and is widely applied to the electronics industry.
Description
[technical field]
The utility model relates to a kind of fixed structure of light emitting diode, and what be specifically related to is the fixed structure that is applied to the light emitting diode in the LED lamp billboard.
[background technology]
The light emitting diode of existing application in LED lamp billboard generally is provided with a screens on the terminal pin of the fixed structure of light emitting diode.After like this terminal pin being inserted circuit board, screens will stop that terminal pin continues to insert in circuit board, the fixed structure of light emitting diode is welded on the circuit board afterwards again.Housing on the fixed structure of light emitting diode will have certain distance from the surface of circuit board like this, housing just may bending under the effect of external force like this, irregular phenomenon just appears in the light that sends at the fixed structure of a plurality of light emitting diodes like this, like this image effect that demonstrates in the LED lamp billboard and bad.
The utility model is being made in such cases.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art and provide a kind of simple in structure, the fixed structure of effective light emitting diode.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of fixed structure of light emitting diode, include led lighting spare and the housing that is sealed in led lighting spare head, the terminal pin of described led lighting spare is welded on the circuit board, it is characterized in that being extended with feet downwards at housing bottom, and this feet withstands on the circuit board.
The fixed structure of aforesaid a kind of light emitting diode is characterized in that being provided with a locating hole on circuit board, described feet withstands in the locating hole.
The fixed structure of aforesaid a kind of light emitting diode, the number that it is characterized in that described feet is 2.
The utility model compared with prior art has following advantage: after the terminal pin of the utility model light emitting diode is welded on circuit board, be extended with feet downwards at housing bottom again, two terminal pins owing to housing all contact with circuit board with feet like this, realized three-point fix, so the phenomenon of bending can not appear in housing, the light that the fixed structure of a plurality of like this light emitting diodes sends just in good order, the image effect that demonstrates in the LED lamp billboard is very good like this.
[description of drawings]
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the stereogram of light emitting diode.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
A kind of fixed structure of light emitting diode includes led lighting spare 1 and the housing 2 that is sealed in led lighting spare 1 head.The terminal pin 3 of described led lighting spare 1 is welded on the circuit board 4, is extended with feet 5 downwards in housing 2 bottoms, and this feet 5 withstands on the circuit board 4.Because two terminal pins of housing all contact with circuit board with feet, realized three-point fix, so the phenomenon of bending can not appear in housing, the light that the fixed structure of a plurality of like this light emitting diodes sends just in good order, the image effect that demonstrates in the LED lamp billboard is very good like this.
As the optimal way of present case, on circuit board 4, be provided with a locating hole 6, described feet 5 withstands in the locating hole 6.
As the optimal way of present case, the number of described feet 5 is 2.
