The method analysis and protect reason for led

The paper introduction of base concept of led ,the reason of damage and protect electrical circuit.LED base concept (LED is light emitting diode)is semiconductor it put the electrical energy into light energy , it adopt electrical to lit.base on analysis , the character of led is obvious , for example it has long service time, excellent efficiency , no radiation and low power,the optical spectrum almost focus into vision frequency channel , the optical efficiency can reached 80~90%,the high power is light power rate, in generally refer to 0.5W,1W3W5W or upper , lit angel refer to aggregate state of light  led protect,
In specify electrical circuit, we can using the protect circuit as follows,bypass protect, there are many branch is in led serial electrical circuit, we can add a PTC component to protect led in echo branch, this is method as high accuracy and stability
Protect led in generally
Add a PTC component to protect led in generally in echo group led. the advantage of solution is simply , the user was satisfied with the results of the method,
In summary , this paper has been introduction of base concept , the reason of damage and the method of protect led, first we talk about the led concept , then we has analysis that the reason of led damage,
finial we has been refer to some method to protect led. and we introduce electrical circuit of led. wish it is valid information for your led project.
