The changing range of LED lamp bead VF is not considered, resulting in low efficiency of the lamp, and even the price load of the LED light source module in unstable LED light source module. It is generally composed of several LED string of LEDs. quantity. LED's VF changes with temperature changes. Generally, at the constant current, VF becomes lower at high temperature, and VF becomes high at low temperature. Therefore, the working voltage of the LED lamps load at high temperature corresponds to VOL, and the LED lamp load load operating voltage at low temperature corresponds to VOH. When choosing the LED drive, the driver's output voltage range is greater than VOL VOH. If the price of the LED light source module to the large output voltage is lower than VOH, the tolerance of the lamp at low temperature may not reach the actual power. If the selected LED drive to the low voltage is higher than VOL, the drive may be driven at high temperature at high temperature. The output exceeds the scope of the working, the work is unstable, the lamps will flash, etc. But comprehensive cost and efficiency consideration, you cannot blindly pursue the range of the LED driver's ultra -wide output voltage range: because the driver voltage is only in a certain range, the drive efficiency is the highest efficiency. After exceeding the range, efficiency and power factor (PF) will deteriorate. At the same time, the design of the output voltage range of the driver is too wide, which will lead to increased costs and efficiency cannot be optimized. If the power balance and reduction requirements are not considered, the nominal power of the LED drive refers to the data measured by the rated environment and the rated voltage. Considering that different customers will have different applications, most LED drive suppliers will provide a power reduction curve on their own product specifications (common load VS ambient temperature drop curve and load VS input voltage reduction curve)). The red curve indicates that when the price of the LED light source module is input 120VAC, the power reduction curve with the ambient temperature changes. When the ambient temperature is lower than 50 C, the driver allows 100 full loads. When the ambient temperature is as high as 70 C, the driver can only reduce the load to 60%. When the ambient temperature changes between 50-70 C, the drive load of the drive is with the temperature with the temperature with the temperature Rise and linear decline. The blue curve indicates that when the LED driver enters 230VAC or 277VAC, its load has a power reduction curve with the changes in the ambient temperature. The blue curve means that when the LED driver is 55 C, the output power reduction curve with the changes in the input voltage changes. When the input voltage is 140VAC, the load of the driver allows 100 full loads, and as the input voltage is reduced; if the output power remains unchanged, the input current will rise, resulting in the increase in input end loss, the efficiency decreases, the temperature of the device will rise, the individual temperature points may be possible. Excessive standards may even cause devices to fail. Therefore, when the input voltage is less than 140VAC, the output load of the driver is required to be reduced with the input voltage and the linear decrease. After understanding the upper reduction curve and the corresponding requirements, when choosing the price of the LED light source module, you should comprehensively consider and choose according to the actual environmental temperature and input voltage conditions, and leave appropriately to leave the reduction of the reduction of the reduction of the reduction amount.

The product has different levels of functions, but for industrial supplies, a set of UVLED curing machines that can really be called good can be called more important than stable performance and security performance. Imagine that on the assembly line, the product continues to flow in the set process. If the UVLED solidifier in the UVLED curing process is separated by the downtime of the three forks, the bad products generated, the delayed production time, the conversion of the cost, the converted into cost, Perhaps the cost of the UVLED curing machine is several times or even dozens of times more expensive. If the luck is almost almost almost, if the after -sales service is not timely, maybe the misunderstanding will be higher. Tianhui has been serving various industries for twelve years, knowing the needs of customers, so it comes standard on Tianhuiuvled Cleeing equipment. During the process, the whole process gives protection and early warning. Why dare to say that your equipment is stable and safe? It is because the functions of the chips, lamps, heat dissipation systems, alarm functions of each set of equipment of Tianhui have been inspected for a long time. According to market research and customer feedback, the average service life of Tianhuvled CICS can reach 30,000 hours average. And the light output of the device is stable, uniform, and luminous rates, which have been well received by customers. Since Tianhui has gone through, there are very few after -sales service. Sometimes when Tianhui visits customers, I asked why there is no technical communication after buying the machine. Is it the machine to buy it? It's very simple, so there is nothing to communicate. The application of Tianhuiuvled Line light sources is widely used. Many customers cooperate with TianhuiuVLED line light sources and point -to -replenish machines to achieve the rapid sealing and assembly line operation of the chip. Some customers recognize the characteristics of TianhuiuVled cold light source without heat radiation and small temperature rise. Apply the device for the production of LCD monitors, and to the liquid crystal edge of the liquid crystal through the UVLED wire light source. At present, there are many choices for customers to provide customers. It is also difficult to find a UVLED curing machine with satisfaction and price. If you are looking for a UVLED curing machine, you may wish to try Tianhui's UVLED product.

As a non -optical component in the water -based UVLED curing ink, the competition of pigments and causes to absorb UVLED light, which greatly affects the solidification characteristics of the system in the UVLED curing system. Since the pigment can absorb a part of the radiation energy, this will affect the absorption of light caused by the light cause, and then affect the concentration of the free radicals that can be generated. As a result, it will reduce the curing speed. Each color has different absorption rates (light transmission) of different wavelengths. The smaller the absorption rate of the pigment, the greater the light transmission rate, and the faster the coating. Carshrilia's ultraviolet absorption capacity is high, the slowest solidification, strong white pigment reflector, which also hinders solidification. Generally speaking, the order of absorption of ultraviolet light is: black> purple> blue> blue> green> yellow> red. Different colors are different, and the concentration of pigments of the same color is different. The effect on the fascination of ink membrane is different. As the amount of pigment increases, the curing rate of the ink film has decreased to varying degrees. Among them, the amount of yellow paint has the greatest effect on the curing rate of the ink film, followed by red pigments and green pigments. Because the black absorption rate on ultraviolet light is the highest, the light transmission rate of black ink is the lowest, so the change of the amount of dosage has no significant effect on the curing rate of the ink film. When the amount of pigments is too large, although the curing rate of the surface layer of the ink membrane is fast, the surface of the surface of the surface absorbs a large amount of ultraviolet light, reduces the light transmission of ultraviolet light, affects the curing of deep ink membranes. Do not solidify, it is easy to produce "wrinkle skin" phenomenon. In summary, the color of the pigments is different from the concentration of the pigment that affects the water -based UVLED ink light. After understanding the reason, we should be targeted when selecting the UVLED optical curing system. Different from irradiation time, etc. The effect of the pigment curing is also different.

When many customers use UVLED curing machines, there will be a question: Since it is generated by the ultraviolet reaction, will there be a situation where the surface is dry and the internal drying is different? It does exist, so how does UVLED optical curing achieve the solidification effect? A variety of UVLED optical curing TIANHUIUVLED solidification machines can be divided into two stages. One stage is through UVLED light reaction (UVLED optical reaction), and the other is through thermal curing, humidity optical curing, oxidation oxidation, oxidation, oxidation, Dark reactions such as light curing or anaerobic optical curing. In this way, the system can be used to quickly shape the system or achieve "drying", and the "shadow" section or inner layer can be fully solidified by dark reasons to achieve "practical dryness". Dual UVLED optical curing extends the application of UVLED optical curing adhesive between opaque medium, complex shaped substrate ultra -thick glue layer and non -colored rubber layer. This system gives UVLED optical curing adhesives more powerful competitive. UVLED curing machines are usually, UVLED curing machines generally act on the adhesion and curing of transparent objects (or transparent parties to both parties), as well as the surface coating of the product. The system and opaque material are difficult to deeply solidify, including the shape of some product components is too complicated, and it is not conducive to UVLED optical curing solidification. In response to this problem, Tianhui has been developed and tested, using the dual UVLED optical curing system combined with UVLED optical curing and other UVLED optical solidification methods to complete the above solid difficulties through two independent reactions in the stage of different reactions principles. Provide you with a more comprehensive and effective UVLED optical curing solution, Tianhui (WHLX), has been focusing on the research and development and sales of UVLED curing machines for many years. Tianhui, provide you with more comprehensive and effective UVLED optical solid solution.

Deep solidification of ultraviolet radiation, the main condition is that the molecule must absorb light quantum with sufficient energy and become a stimulating molecule, break down into free radicals or ions, so that unsaturated organic matter can be aggregated, proclapped, and cross -linking to achieve the purpose of solidification Essence Among them, the energy of the UVLED energy in the UV coatings of the UV coatings exceeds or less than that of the energy required by the UVLED required by the known light cause. .2, I do nt know that the UVLED energy required by the light caused by the light cause, blindly supplying it blindly. This approach not only wastes energy, but also causes excessive solidification negative effects, such as explosion gathering and anti -solidification reactions. 3. When UVLED is insufficient, the energy of UVLED must be moderate, that is, it cannot be excessive or insufficient, which can be completely solidified.
