The regular appearance size of 3535LED lamp beads is: 3.5*3.5*2.0mm, mostly ceramic substrates, with good heat dissipation performance. The 3535 that can be seen on the market, not only the appearance is slightly different from different manufacturers, but also the photoelectric parameters are almost different, and the chips inside the package are also very different, including 0.5-5W chips. The raw materials of 3535 SMD LED lamp beads are directly purchased by Hongfucheng Optoelectronics; Hongfucheng Photoelectric, a professional high-quality LED manufacturer, has stable performance, good heat dissipation, small light decay, and longer life.

3535LED lamp beads have unique advantages, but LED lamp beads are a fragile semiconductor product, so we should be extra careful when using LED products. Now we will summarize some LED use precautions. Please be highly careful during use. Pay attention to.

(1) DC power supply should be used: In order to reduce product cost, some manufacturers use "resistance-capacitance step-down" method to supply power to LED products, which will directly affect the life of LED lamp bead products. Using a dedicated switching power supply (preferably a constant current source) to supply power to the LED lamp product will not affect the service life of the product, but the product cost is relatively high.

(2) Anti-static measures must be taken: LED lamp bead products must adopt certain anti-static measures in the process of processing and production, such as: the workbench must be grounded, workers must wear anti-static clothing, with anti-static rings, and with anti-static Electrostatic gloves, etc., if possible, install an anti-static ion fan, and at the same time, ensure that the humidity of the workshop is about 65%, so as to prevent the air from being too dry to generate static electricity, especially green LED lamp beads are relatively easy to be damaged by static electricity. In addition, LEDs of different quality grades have different antistatic abilities, and LED lamp beads with high quality grades have stronger antistatic abilities. There may be many friends who are not very familiar with 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 physical quantities related to the nature of electrostatic phenomena, and is called ESD in English.

Quantities related to electric potential, electric field, current, etc. are all physical quantities due to the existence of electric charge or the movement of electric charge. Many electrostatic problems are caused by people's lack of ESD awareness, and even now there are many people who suspect that ESD will cause damage to electronic products. This is because most ESD damage occurs below the human senses, because the human body's perception voltage to electrostatic discharge is about 3KV, and many electronic components are damaged at hundreds or even tens of volts, usually after electronic devices are damaged by ESD There is no obvious boundary, and the components are mounted on the PCB and then tested, and as a result, many problems occur and the analysis is quite difficult. Especially for potential damage, it is difficult to measure obvious changes in its performance even with precision instruments. Therefore, many electronic engineers and designers suspect ESD. In recent years, experiments have confirmed that such potential damage will affect the performance of electronic products after a certain period of time. Reliability drops significantly.
