Description

Antistatic LED Light Emitting Diodes

technical field

The utility model relates to an LED light emitting diode, in particular to an antistatic LED light emitting diode.

Background technique

The application of LED light-emitting diodes in electronic products is very common, and whether it is on the production line or during use, it is very easy to cause the LED light-emitting diodes to burn out due to static electricity. The current LED light-emitting diode electrostatic protection measure is to add an electrostatic protection circuit in the diode, specifically a reverse antistatic diode is connected in parallel at the two poles of the LED, and the diode is directly welded or pasted on the electrode on the surface of the LED crystal. Also because of this, the existing antistatic LED light-emitting diodes have relatively poor operability when making electrostatic protection circuits, and are especially prone to damage to devices, resulting in an increase in product defect rates.

In order to achieve the above object, the utility model adopts the following technical solutions:

An antistatic LED light-emitting diode includes an LED bracket, an LED crystal and an electrostatic protection circuit. The LED bracket is provided with two legs, and the LED crystal is arranged on one of the legs. The electrostatic protection circuit and the LED crystal form a parallel circuit, which is different from the prior art. One, the two ends of the electrostatic protection circuit are respectively welded to the two legs of the LED bracket, rather than directly welded or pasted on the electrodes on the surface of the LED crystal.

Preferably, the static protection circuit includes an antistatic diode, and the antistatic diode and the LED crystal form a reverse parallel circuit.

Compared with the prior art, the utility model has the beneficial effects of:

The two ends of the electrostatic protection circuit are respectively welded to the two legs of the LED bracket, instead of being directly welded or pasted on the electrodes on the surface of the LED crystal. When making the electrostatic protection circuit, the operability is greatly improved and the protection of the device is enhanced. Effectively reduces the defective rate of the product, and the antistatic ability of the product can reach more than 8500V (human body model).
