LED has a unique advantage, but the LED is a fragile semiconductor products, LED products to be extra careful, I now summarize some LED Note attaches great importance to the process of using the.
(A) DC power supply should be used diode led
Some manufacturers in order to reduce the cost of the product using the RC Buck to LED product supply, which will directly affect the life of the LED products. Dedicated switching power supply (preferably a constant current source) to the supply of LED products will not affect the service life of the product, but the relatively high cost of the product.
(B) shall make anti-static measures
LED products to be used in the production process in the processing of certain anti-static measures, such as: table to be grounded, workers wear anti-static clothing, with anti-static ring, as well as with anti-static gloves, can install anti-static ion conditional fans, as well as to ensure the workshop humidity around 65%, in order to avoid the air is too dry to produce static electricity, especially the green LED is more easily damaged by static electricity. LED antistatic ability of different quality grades are not the same, high grade quality LED lights antistatic ability is stronger. May not have a lot of friends on the electrostatic know very well that I am here in more detail about the knowledge of static electricity: static essence remaining charge. The charge is all diode led the physical quantities of the essential aspects of electrostatic phenomena called the ESD.
The amount of potential, electric field, current, etc. are generated due to the presence of the charge or the movement of the charge quantities. A lot of static electricity problems are caused because people do not have ESD awareness, even now there are many people suspected of ESD will damage electronic products. This is because the the most ESD damage occurred following the feeling of the people, because the perception of the human body electrostatic discharge voltage of about 3KV many electronic components can be damaged when a few hundred volts or tens of volts, usually electronic devices are ESD damage no clear boundaries, the components are mounted on the PCB, after re-testing, the results of a lot of problems, analysis quite difficult. Potential damage, that is, the use of sophisticated instruments it is difficult to measure its performance significantly change, so it is all electronic engineers and designers are skeptical ESD, in recent years, but experiments diode led confirmed that this potential damage after a certain period of time, electronic products The reliability decreased significantly.
