Abstract
The utility model relates to an LED, in particular to an antistatic LED, comprising an LED support, an LED crystal and an electrostatic protection circuit, wherein, the LED support is provided with two legs; the LED crystal is arranged on one leg; the electrostatic protection circuit and the LED crystal form a parallel circuit; and two ends of the electrostatic protection circuit are respectively welded to the two legs of the LED support rather than directly welded or glued to an electrode on the surface of the LED crystal. When the electrostatic protection circuit is produced, the maneuverability is greatly improved comparatively, the protection to elements are strengthened, the product fraction defective is effectively reduced, and the product antistatic capacity can reach over 8,500 V (human body model).
Description
Technical field
The utility model is a kind of LED light emitting diode, especially a kind of anlistatig LED light emitting diode.
Background technology
The application of LED light emitting diode in electronic product is very general, and it is no matter on production line or in the use, very easily because static causes the LED light emitting diode to burn then.The LED light emitting diode electrostatic protection measure of adopting is to increase electrostatic discharge protective circuit in diode at present, specifically is reverse antistatic diode in parallel at LED the two poles of the earth, and diode directly welds or sticks on the electrode of LED plane of crystal.Also Just because of this, existing antistatic LED light emitting diode is when making electrostatic discharge protective circuit, and operability is poor, damages device especially easily and causes the product fraction defective to rise.
The utility model content
The utility model has proposed a kind of anlistatig LED light emitting diode in order to overcome the defective of prior art, has mainly improved the syndeton of electrostatic discharge protective circuit and LED crystal.
To achieve these goals, the utility model has adopted following technical scheme:
Anlistatig LED light emitting diode; comprise led support, LED crystal and electrostatic discharge protective circuit; led support is provided with bipod; on the LED crystal pin located therein; electrostatic discharge protective circuit and LED crystal constitute parallel circuit; unlike the prior art be one, the two ends of electrostatic discharge protective circuit are welded on the bipod of led support respectively, rather than directly weld or stick on the electrode of LED plane of crystal.
Preferable, described electrostatic discharge protective circuit comprises antistatic diode, antistatic diode and LED crystal constitute reverse parallel circuit.
Compared with prior art, the beneficial effects of the utility model are:
The two ends of electrostatic discharge protective circuit are welded on the bipod of led support respectively; rather than directly weld or stick on the electrode of LED plane of crystal; when making electrostatic discharge protective circuit; operability improves more greatly; strengthened protection to device; effectively reduced the product fraction defective, the product antistatic effect can reach 8500V above (Human Body Model).
Description of drawings
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with Figure of description and concrete enforcement the utility model is described further, but the scope that the utility model is protected is not limited thereto.
As Fig. 1, Fig. 2 and shown in Figure 3; anlistatig LED light emitting diode; comprise led support 1, LED crystal 2 and electrostatic discharge protective circuit 3; led support 1 is provided with bipod; on the LED crystal 2 pin located therein; described electrostatic discharge protective circuit 3 comprises antistatic diode 4; antistatic diode 4 constitutes reverse parallel circuit with the LED crystal 2; unlike the prior art be; the two ends of electrostatic discharge protective circuit 3 are welded on the bipod of led support 1 respectively, rather than directly weld or stick on the electrode on LED crystal 2 surface.Therefore, when making electrostatic discharge protective circuit, operability improves more greatly, has strengthened the protection to device, has effectively reduced the product fraction defective, and the product antistatic effect can reach 8500V above (Human Body Model).
