LED has a unique advantage, but LED is a fragile semiconductor product, so we must be extra careful when using LED products , now I will summarize some LED usage precautions, please pay attention to the use process. (1) Should be powered by DC power Some manufacturers use the "resistance-resistance and step-down" method to supply power to LED products in order to reduce the cost of products, which will directly affect the life of LED products. Using a dedicated switching power supply (preferably a constant current source) to power the LED products will not affect the life of the product, but the product cost is relatively high. (2) Antistatic measures must be taken LED products must adopt certain anti-static measures in the process of processing and production, such as: workbench should be grounded, workers should wear anti-static clothing, with anti-static ring, and with anti-static gloves, etc., can be installed with anti-static ions The fan should also ensure that the humidity in the workshop is about 65%, so as to prevent the air from being too dry to generate static electricity, especially the green LED is relatively easy to be damaged by static electricity. In addition, the antistatic ability of LEDs of different quality grades is also different, and the antistatic ability of LEDs with higher quality grades is stronger. There may be many friends who don't know much about static electricity. I will introduce the knowledge of static electricity in detail here: The essence of static electricity is the existence of residual charge. Charge is all the physical quantity related to the nature of electrostatic phenomena. English is called ESD. The quantities related to potential, electric field, current, etc. are physical quantities due to the presence of charge or the movement of charge. A lot of static problems are caused by people's lack of ESD awareness, and even now many people suspect that ESD will cause damage to electronic products. This is because most ESD damages occur below human perception because the human body's perceived voltage for electrostatic discharge is about 3KV, and many electronic components can be damaged at hundreds of volts or even tens of volts, usually after the electronic device is damaged by ESD. There are no obvious boundaries. After the components are mounted on the PCB and then tested, there are many problems and the analysis is quite difficult. Especially the potential damage, that is, it is difficult to measure the performance of the instrument with the use of precision instruments, so most electronic engineers and designers are skeptical about ESD, but in recent years, experiments have confirmed that this potential damage after a certain period of time, electronic products Reliability has dropped significantly. Solar energy is an inexhaustible, clean, pollution-free and renewable green energy. Photovoltaic energy is considered to be the most important new energy in the 21st century because of its advantages such as incomparable cleanliness, high security, relative extensiveness and sufficiency of energy, long life and maintenance free. The Solar Street Light does not need to be wired, does not need ac power supply, does not generate electricity. Dc power supply and control; It has the advantages of good stability, long life, high luminous efficiency, simple installation and maintenance, high safety performance, energy saving and environmental protection, economy and practical. It can be widely used in urban main and secondary roads, small areas, factories, tourist attractions, parking lots and other places. Solar street lamp is green, energy-saving, cost-reducing, long service life, stable product structure, and has very good social and economic benefits.
