Regarding the advantages and application fields of UVLED light source curing machines, Tianhui has been told in detail in previous articles. Interested friends can read the previous article. What I want to share with you today is how to detect the solidification of the UVLED light source. How to judge whether the glue or ink that has been irradiated by the UVLED light source curing machine has been solidified, it is also the recent question of more customer consultation. Here I will share with you the method and step of detecting UVLED light source solidification. I hope it will be helpful to you! 1. Use the surface of the paper and the membrane layer to hold it with the hand. If the surface layer is solidified and the bottom layer is not solidified, the surface layer will be worn out; Completely, basically you can't smell any smell. If you smell the smell of light oil, it means that there is an unsatisfactory ingredient; 3. Use a large head needle to draw the surface layer of the membrane layer, and then use 200 times the large mirror observation. The scratch is jagged. It indicates that it has been solidified; 4. Use acetone or ethanol to drip on the surface of the membrane layer. If the membrane layer is quickly dissolved, it means that it is not completely cured by the UVLED light source solidifier. Tianhui is committed to providing more useful and cost -effective UVLED solidification products and solutions for the entire industry UV curing technology.

Some research reports show that deep -ultraviolet DUVLEDs featuring high -tech innovation are widely used, which will become a new hot spot for global LED research and investment. Excessive investment development makes the LED blue and green light market quickly become the Red Sea, while the deep -ultraviolet Duvled market is still a blue ocean. So how deep is this blue sea water? What are the preparations to enter this market company? Deep UV light (UV) refers to the light waves between 100nm and 280nm. The UVLED light source has significant application value. The luminous wavelength of the deep ultraviolet DUVLED in the active area of Algan can cover the ultraviolet band of 210-365nm. It is an ideal material for realizing the DUVLED device product. In the future, the LED market will be divided into two parts, one is the visible light LED for general lighting, and the other is the deep ultraviolet UVLED feuded by high -tech innovation. At present, most of the investment in the LED industry has poured into the field of red and blue and green light. Excessive investment makes the LED blue and green light market quickly become the Red Sea, and the deep ultraviolet LED market is still a blue ocean. Its vast market prospect has become a new hotspot in global LED research and investment after semiconductor lighting LED. UVLED is widely used, including: disinfection of drinking water, air, beverages, and drug packaging; surgical equipment disinfection and sterile state; in the refrigerator, kill surviving mold spores, and further extend the food preservation period. In addition to disinfection, UVLED can also perform optical chemical catalysis, ink curing, etc. With the development of science and technology, deep -ultraviolet LED replacing the original application technology and products has broad market application prospects. We will compare the deep ultraviolet LED with some of its products. The use of low -pressure mercury lamps can sterilize, but because mercury is likely to cause harm to the environment, researchers have always hoped to find good environmental environmental protection alternatives. Deep ultraviolet rays are a relatively short wavelength ultraviolet rays, which are relatively efficient to kill bacteria and viruses. Although the total output power of traditional mercury lamps is large, the unit area output is strong but very weak, only one percent of 280 nanometer ultraviolet light light diode. Therefore, the deep ultraviolet 280 nanometer band LED is more suitable for fast disinfection than traditional mercury lamps, and the equipment volume is particularly small. Traditional UV lights: Due to the needs of traditional ultraviolet lights, compared with LEDs that belong to semiconductor products, the volume is very large and requires high -voltage Qihui. In addition, although the total output power of traditional mercury lamps is high, the unit area output is strong but very weak, only one percent of 280 nanometer ultraviolet light light diode. Therefore, the deep ultraviolet 280 nanometer band LED is more suitable for fast disinfection than traditional mercury lamps, and the equipment volume is particularly small. Comecades: Comecades Deep UV -based deep -ultraviolet LEDs based on aluminum -based aluminum -based ilgan 镓 (Algan) materials have the advantages of solid, energy saving, long life, and no mercury -free environmental protection. At present, the LED lighting market is big and purple, but the harm of Blu -ray has also entered people's vision, causing discussions in the industry. How big is Blu -ray harm? No conclusion is currently. So does deep ultraviolet LED hurt the human body? At present, the LED power of the deep ultraviolet 280 nanometer band of the ultraviolet industry is very small. And the LED unit area illuminates with the square of the distance. Therefore, besides the distance between sterilization work, the effect of deep ultraviolet LED on human skin is small; in addition, deep ultraviolet LEDs are small and easy to hide design. Ordinary glass and plastic with less than 0.1 mm thick can completely absorb deep ultraviolet rays. Just like the lighters, tools, power sockets, etc. in daily life, as long as it is used correctly, the safety of the reasonable design of ultraviolet LED supplies is completely guaranteed. With the development of China's economy and the improvement of living standards, people will pursue more high -quality life and pay more attention to health. These needs will inevitably stimulate the development of the UVLED application market. Zhuhai Tianhui Technology is based on high -end advanced technology, and is willing to work with you.

How to repair the LED light? Zhuhai teaches everyone to learn to do it. Simple LED faults can also repair themselves. LED lights are different from the previous incandescent lamps. The incandescent lamps are basically broken. Basically, tungsten filaments are burned. LED lights are different. LED lights are composed of LED drive circuits and LED lamp beads. Most of the LED lights can be repaired, but the price of LED lights is not high. Dozens of dozens, so no one specializes in repairing LED lights, the price is high, others are unwilling to repair, the price is low, the labor cost is too low, so it can only be repaired by users. How to repair LED lights as general users? There are many reasons for the failure of LED lights, but there are some failures that are relatively simple. It is recommended that users can try to repair themselves and practice as practicing. LED lamps often see faults and maintenance methods 1. LED lamp beads are damaged. This is a very common failure. Generally, when LED lamp beads are burned, there will be black spots on the surface. Careful observation can be distinguished. For this fault repair, you need to equip a soldier iron. But what if there is no LED lamp bead? Can use 150ωThe left and right resistance replaces, if the constant current driver can be directly connected. 2. Filter capacitance failure. The simple LED light generally rectifies the AC electricity through the tolerance and lowering the pressure, and then power the LED lamp beads through the capacitor filtering. If the filter capacitor failure will cause the voltage unstable, the DC voltage is low, which makes the LED light darker. Measure the capacity of the filter capacitor with a multimeter capacitor file. If the error is large, the error is greater than about 30%. It means that the capacitance has deteriorated. Find a voltage resistance and capacity that is greater than equal to the capacitor parameter. 3. The capacity resistance drop -down module is damaged. The capacity resistance drop module consists of a capacitor capacitor and resistance parallel. It can be used to measure whether its capacitance and resistance can be damaged. 4. Return. Disassemble the LED light and check whether there is a disconnection at the internal input and output wiring. If so, use the electric soldering iron to fix it. 5. Rectification diode fault. There are faults such as opening roads and short circuits, which may be caused by over -flowing, or it may be caused by long -term use of failure. Find a rectifier diode with a reverse voltage resistant value greater than 350V and the working current greater than 0.5A, such as 1N4004 1N4007, etc. 6. LED constant current driving circuit failure. For professionals who need some electronic -related experience in this kind of failure to repair, they can find the technical staff of Zhuhai manufacturers for maintenance. The manufacturer specializes in the production of LED lamp beads. It is rich in experience. It is better to replace a new LED lamp bead after the above simple failure.

The performance of a UVLED curing device is largely set to the performance of the power supply. Therefore, the design of the power supply supply is very important. This article combines the development experience of Tianhui's company to discuss several commonly used topological structures of the UVLED drive power supply. 1. The BUCK switch -type adjustor topological BUCK circuit is a downwriting type cutting circuit. Its output voltage is always smaller than input voltage (that is, VO

As customers often call to consult UVLED glue curing machines, some customers also mention that the speed of curing is fast enough. However, there are two aspects of the factors that affect UVLED glue curing: 1. CICF: Depending on substrate, coating, curing interval, etc., appropriate adjustment of the device curing speed. The speed of curing is too fast, and it is prone to the appearance of the base material UVLED glue sticking or drying the appearance; if the operating speed is slow, the appearance of the substrate will be aging. 2. UVLED glue coating: The thickness of UVLED glue coating plays a vital role in the solidification of UVLED. The coating is too thick, and the time is relatively long under the illumination of the same power light source. On the one hand, it affects the curing of UVLED glue. On the other hand, it will make the appearance of the substrate's appearance too high, which will cause the product's appearance differential glory difference. In fact, the curing rate of UVLED glue, the final curing depth and the drying effect are related to the factors such as ultraviolet light sources, lighting time, and material light transmission. It is recommended to determine the specific solidification time through the test. Our company's UVLED glue curing machine has three bands: 365, 395, and 405 UVLED curing machines, and the irradiation power is different. The adjustable power irradiation intensity can be contacted. There is a one that can meet your requirements.
