Now we will summarize some LED use precautions. Pay attention to. (1) DC power supply should be used: some manufacturers use in order to reduce product costs“Resistance”Power on LED products by way, which will directly affect the life of LED lamp products. Adopting a special switching power supply (preferably a constant stream source) product supply to LED lamp bead products will not affect the service life of the product, but the product cost is relatively high. (2) Anti -electrostatic measures must be taken: LED lamp bead products must adopt certain anti -static measures during the process of processing and production, such as: workbench to be grounded, workers should wear anti -static clothing, anti -static electrical ring, and anti -anti -anti -prevention ring Static gloves, etc., those who have conditions can be installed with anti -static ion fans, and also ensure the humidity of the workshop at about 65%, so as not to be too dry to produce static electricity, especially the green LED lamp beads are relatively easy to be damaged by electrostatic damage. In addition, different quality -grade LED anti -static capabilities are also different. LED lamp beads with high quality grade should be stronger. There may be a lot of friends who do not know the static electricity very well. I will introduce the knowledge of static electricity in detail here: the essence of static electricity is the surplus charge. Charge is the physical quantity of all the essence of static electricity. English is called ESD. Related amounts related to potential, electric field, current, etc. are all physical quantities caused by the existence of charge or the movement of the charge. Many electrostatic problems are caused by people without ESD consciousness. Even now, many people suspect that ESD will cause damage to electronic products. This is because most ESD damage occurs below the human feeling, because the human body's perceived voltage of static discharge is about 3KV, and many electronic components will be damaged when they are hundreds of volts or even dozens of volts. Usually, when the electronic devices are damaged by ESD There is no obvious boundary, and the component is installed on the PCB before detection. As a result, there are many problems, and the analysis is quite difficult. Especially for potential damage, it is difficult to measure the performance of its performance even with precision instruments, so both electronic engineers and designers have suspected ESD. In recent years, the experiment has confirmed that this potential damage will be Reliability decreases significantly. (3) The temperature of LED lamp beads: Pay attention to the increase in temperature to make the internal resistance of LED lamp beads smaller. After the environmental temperature of the outside world increases, the internal resistance of the LED lamp beads will be reduced. The working current rises. When the working current exceeds its rated work current, it will affect the service life of LED products. It will seriously make LED lamp beads light sources“Burn out”Therefore, it is best to use Hengli source power supply to ensure that the working current of the LED is not affected by the external temperature. The temperature of LED lamp beads is also the most important factor affecting the LED life. Please pay attention to it. (4) Sealing of LED lamp bead products: No matter what LED lamp products are used, as long as it is applied to the outdoor, it is facing the problem of waterproof and moisture -proof sealing. If it is not handled, it will directly affect the service life of LED products. Now there are a small number of manufacturers with high product quality requirements adopt traditional epoxy resin“water”The method is to seal LED products. This method is more troublesome to operate. It is not very suitable for LED lamp bead products with larger volume, and it will also increase the weight of the product. (5) The current of LED lamp beads cannot exceed the IF current of LED lamp beads: Overcurrent work will make LED lamp beads quickly decrease. If it exceeds over, it will immediately burn LED. (6) LED lamp beads must note: When the LED lamp beads are too close to the colloid when the corner or angle is bent, it should be kept at a distance of more than 2mm from the colloid. The number of foldings in the same place cannot be more than three times, and the corner is bent to 90°Back to the original position once. (7) Welding temperature: The welding temperature is about 260 C, the time is controlled within 5s, and the welding point is above 2.5mm from the bottom of the colloid.

It is an inevitable trend to replace UV mercury lamps in UVLED ultraviolet devices. Many people want to know if UVLED will cause harm to the human body? First figure out the classification of ultraviolet rays: UV-A (315-400 nanometer, also known as long-wave ultraviolet), UV-B (280-315 nanometer, also known as medium wave ultraviolet), UV-C (100-280 nanometer, also also, also It is called short -wave ultraviolet rays; secondly divided purple light and ultraviolet light. At present, purple light and ultraviolet light are often made in the market. In fact, it is two concepts. UV rays generally refer to less than 400nm. Of course Below, UV light is invisible, just like infrared, then purple light refers to 410nm or more, that is, purple light, visible, just like the usual white light, red light, etc. Now answer the question above, is UVLED harmful to the human body? The answer is no, but it is certain that it cannot be directly shot. Is UV light harmful? This should be answered separately. UV-B (280-315 nanometer, also known as medium wave ultraviolet), UV-C (100-280 nanometer, also known as short-wave ultraviolet rays, must be harmful, the sunlight contains these, it contains these, which contains these. Therefore, it is easy to hurt the skin when the sun is very strong, so the UV-B, UV-C reaching a certain amount will definitely hurt the body, so protective measures must be taken. As for UVA, less damage to the body, especially the wavelength of more than 360nm, human skin has a certain protective function, so it can be regarded as no harm to the human body. Of course still can't shoot directly. More information is welcome to log in

LED lamp beads are actually a light -emitting diode. After loading a certain voltage and current, it will glow. Generally speaking, the voltage of a single LED chip is about 3V, and the current is 30mA. For the voltage and current of LED lamp beads, most of them are in the process of LED packaging. The 0.2W LED lamp bead used in the lamp tube is made of two LED chips in parallel, that is, 3V, 60mA. For the high -voltage LED 9V lamp beads that are used mostly, the three LED chips are connected in series, that is, 9V, 30mA. Because the LED lamp beads are co -authored by multiple LED chips, there are many specifications of LED lamp beads, and there are many types of voltage. How much is the specific lamp? You can also see how many LED chips are composed of the lamp beads. Of course, because the LED chip is relatively small, the gold thread of the lead key is relatively small. It can only be estimated to visually. You need to test it with DC source. However, it is 3V, 6V, 9V, etc. Of course, there are dozens of V lamp beads. This depends on what kind of lamp beads do you really need to use?. For only 3V lamp beads, you can use a multi -meter diode file to light up this lamp bead. This is positive and negative. For LED lamp beads that do not know the voltage, it can only be measured by DC. From scratch to larger, when the lamp beads are slightly bright, the voltage at this time is the approximate voltage of LED lamp beads. For COB lamp beads, it is actually a principle, but COB encapsulates more LED chips, and the voltage and current will be relatively large. The confirmation method of COB lamps voltage and current is also confirmed by DC source. Each specification of lamp beads have their own characteristics, some are more cost -effective, and some have better performance. The LED lamp beads of the same specifications between each manufacturer will also be different, so the LED lamp beads are not absolutely good or bad. As long as it is used, it will play his biggest role. Professional customization of various LED patch lamp beads. If you need to consult our customer service, we will solve the problem for you.

Outdoor lighting has been widely used in many demonstration projects at home and abroad. Based on its harsh use environment, the LED light source module must focus on the design of problems such as waterproof, high temperature, lightning strikes and other factors. Hongba Electronics introduces the following methods to prevent the effective way to prevent street lights from being destroyed by lightning and lightning: 1. External lightning protection and internal thresholds are combined with the current general LED light source module. It must be installed on the line and the ground network. These systems constitute an external lightning protection system. This system avoids LED street lights from fire and personal safety accidents caused by direct lightning. The internal lightning protection system refers. This system can prevent sensing lightning and other forms of over -voltage invasion, causing power to destroy, which is an external lightning protection system that cannot be guaranteed. The two are complementary and complementary, completing each other. Internal lightning protection systems are connected to the external lightning protection system or set up an over -pressure protector on many devices, cables, metal pipelines, etc. in the inlet and out of the protected area. 2. Lightning -proof potential connections are the destructive potential difference caused by thunderboltic lighting. The power cords, signal cables, and metal pipelines must be connected with an over -voltage protector. Equivalent connection, each partial equal potential connection must be connected to each other, and the back of the main equal potential is connected to. 3. In addition to the power supply equipment, the LED light source group will also set up some communication equipment to control the switch and brightness of the street lights. These equipment and power supply need to be placed in the lightning zone. The electromagnetic field here is much weaker. 4. High -quality protection equipment -the role of lightning protection module and overvoltage protection module is to connect to the potential system of the protection system in a shorter time (nano -second), so that the electrical levels of the device port. At the same time, the huge pulse energy generated in the circuit is released to the earth through the short route to reduce the potential difference of the interface end of the equipment, thereby playing the role of protecting the equipment. For the LED light source module, the use environment determines that lightning protection is a heavy barn indicator for measuring its performance. Hongba Electronics can customize the driver module of various power and related scale functions according to customer needs.
