1. The heat dissipation technology For the light -emitting diode composed of PN, when the forward current flows from the PN, the PN knot has heating loss. These calories are radiated into the air through bonding glue, irrigation material, heat sinking, etc., and radiated into the air. In this process, each part of the material has heat resistance to prevent heat flow, that is, heat resistance, AC -free LED thermal resistance is the fixed value determined by the device's size, structure and material. The thermal resistance of the light diode is RTH (/w), and the heat dissipation power is PD (W). At this time, the PN knot temperature caused by the heat loss of the current rises to: t () = Rth PD. PN knot temperature is: TJ = TARTH PD, where TA is the ambient temperature. As the rising temperature of the knot will reduce the chance of compounding the PN, the brightness of the glowing diodes will decrease. At the same time, due to the increased temperature increase caused by thermal loss, the brightness of the light -emitting diode will no longer continue to increase with the current proportion, that is, the phenomenon of thermal saturation. In addition, with the rise of the knot temperature, the peak wavelength of glowing will also drift in the direction of the long wave, about 0.2-0.3nm/, which is for the white AC-free LED by the white AC-free LED by coating the YAG fluorescent powder by the Blu-ray chip. The drift of the Blu -ray wavelength will cause the losing match with the fluorescent powder to stimulate the wavelength, thereby reducing the overall lighting efficiency of the white light LED, and the change in the white light color temperature. For power emitting diode, the driving current is generally more than hundreds of millimeters. The current density of the PN knot is very high, so the temperature rise of the PN knot is very obvious. For packaging and applications, how to reduce the thermal resistance of the product, so that the heat generated by the PN knot can be emitted as soon as possible, which can not only improve the saturation current of the product, improve the light efficiency of the product, but also improve the reliability and life of the product. In order to reduce the thermal resistance of the product, the choice of packaging materials is particularly important, including heat sinking, adhesive, etc. The heat resistance of each material should be low, that is, the heat conduction performance is good. Secondly, the structure design should be reasonable. The thermal conductivity between each material is continuously matched, and the thermal conductivity between the materials is good to avoid generating heat dissipation bottlenecks in the thermal conductivity. At the same time, it is necessary to ensure from the craftsmanship, the heat is emitted in time according to the pre -designed heat dissipation channel. 2. The choice of filling glue According to the law of refraction, when the light is incident from the light media to the light sparse medium, when the incident angle reaches a certain value, that is, when the critical angle is greater than the critical angle, the full launch will occur. In terms of GAN blue chip, the refractive index of GAN materials is 2.3. When the light is shot from the crystal to the air, according to the law of refraction, the critical angle 0 = sin-(n2/n1) is The refractive index, N1 is the refractive index of GAN, thereby calculating the critical angle 0 about 25.8 degrees. In this case, only the incident angle 25.8 degrees in the three-dimensional corner of the space in the three-dimensional corner of the space is reported. At present, the external quantum efficiency of the GAN chip is about 30%-40%. Therefore, due to the internal absorption of the chip crystal absorption , The proportion of lighting to the outside of the crystal is very small. According to reports, the external quantum efficiency of the GAN chip is currently around 30%-40%. Similarly, the light emitted by the chip must be transmitted to the space through the packaging material, and the effect of the material on the lighting efficiency of the material must be considered. Therefore, in order to improve the lighting efficiency of AC -free LED products packaging, the value of N2 must be increased, that is, the refractive index of the packaging material to improve the critical angle of the product, thereby improving the product packaging lighting efficiency. At the same time, the absorption of lighting materials for packaging materials should be small. In order to increase the proportion of light out of light, the shape of the packaging is arched or hemispherical. In this way, when the light is shot from the packaging material to the air, it is almost vertically shot to the interface, so no full reflection will be generated. 3. There are two main aspects of the reflection treatment reflection treatment. One is the reflection treatment inside the chip, and the other is the reflection of the packaging materials to the light. Through the reflection of the inside and outside, it will increase the proportion of the optical pass from the internal of the chip, reduce The internal absorption of the chip, improve the power AC -free LED finished product lighting efficiency. In terms of packaging, power -type LEDs usually assemble the power -type chip on a metal bracket or substrate with a reflective cavity. The bracket -type reflex cavity generally uses an electroplating to improve the reflection effect. Methods, electroplating treatment is also performed, but the above two methods are affected by mold accuracy and process. At present, the domestic reflex cavity of a sheet -type type, due to insufficient polishing accuracy or the oxidation of the metal coating, the reflex effect is poor, which has caused many light to be absorbed after the reflection area is ejected, and it cannot be reflected to the light surface at the expected target, which leads to reaching to reaching to reaching the expected target, which leads to reaching reaching to reaching the expected target, which leads to reaching reaching to reaching to reaching to reaching the expected target, which leads to reaching to reaching to reaching to reaching the expected target, which leads to reaching to reaching to reaching to reaching the expected target, which leads to reaching to reaching to reaching the expected target, which leads to reaching to reaching to reaching to reaching the expected target, it will lead to reaching reaching to reaching to reach The lighting efficiency after the packaging is low. We have developed a reflex treatment process with an organic material coating with independent intellectual property rights with independent intellectual property after many research and experiments. The light shot above it reflects to the out of light. The processing efficiency of the product after processing can be increased by 30%-50%compared to processing. The light effect of our current 1W white light power LED can reach 40-50LM/W (test results on the distance PMS-50 spectrum analysis test instrument), and have obtained a good packaging effect. 4. In terms of white power AC -free LED, the improvement of light power AC is also related to the selection and process processing of fluorescent powder. In order to improve the efficiency of fluorescent powder to stimulate the blue chip, first of all, the choice of fluorescent powder should be appropriate, including stimulating wavelength, particle size, and inspiration efficiency. Secondly, the coating of fluorescent powder should be evenly coated, and the thickness of each luminous chip with a relatively luminous chip is evenly thick, so as not to cause the local light cannot be shot due to uneven thickness. Good heat dissipation design plays a significant effect on improving the power -free LED product lighting efficiency, and it is also the prerequisite for ensuring product life and reliability. And the well -designed lighting channel, here to refer to the structural design, material selection and process processing of reflection cavity, filling glue, etc., which can effectively improve the lighting efficiency of the power -type LED. For the power -based white light LED, the choice and process design of fluorescent powder is also very important to improve the improvement of light spots and the improvement of lighting efficiency.

Considering how technology is reshaping the market, the printing sector is thriving more than ever. Businesses are currently creating new methods for printing ideas and enhancing collateral, demos, and other types of media.

In numerous industries, UV printing is the next-best option to conventional printing and is one of the newest technologies that has revolutionized how businesses publish ideas. UV printing was practically unknown until recently. Due to its many advantages over conventional printing, UV printing is currently popular among printers.

The inks and the corresponding drying procedure change for conventional and UV printing, although the printing process is nearly the same in both cases.

UV Printing – The Reality Unveiled

UV ink employs UV light to dry ink as quickly as it contacts the material you're utilizing for the prints, in contrast to traditional ink, which utilizes printing methods that depend on heat to solidify evaporating solvents, pigments, and binders. Its UV light gives your print process a competitive edge in several ways, whether printing on paper, aluminum, acrylic, foam boards, or any material that suits a UV printer.

When ultraviolet light strikes UV ink at a specific wavelength, it reacts chemically with colors, binders, and photo initiators to produce a cross-linking chain effect. The UV ink hardens throughout this procedure, making this the newest printing technique for many businesses. 

What Distinguishes UV Printing From Traditional Printing?

You can be excused if you've never heard of electronic UV printing. There are a variety of benefits for both the printer company and the end user. Thus many manufacturers and printers are starting to provide this innovative technology. Conventional and UV printing requires printing; the main differences between the two are the pigments and the drying procedures used. Solvent inks are used in conventional offset printing. However, they are not the greenest choice because they dissipate into the air and release VOCs (Volatile Organic Compounds).

Spray powders are sometimes used. As a result, it speeds up the drying process, although doing so might dilute the natural color and give it a dreary aspect. The disadvantage of using conventional inks is that they are not utilized on other materials like foils, plastics, or acrylics since they are incorporated into the paper.

Compared to traditional paper ink, UV inks operate extremely differently. The UV inks dry by a photomechanical process as opposed to being absorbed.

A UV light is applied to the ink during the printing, rapidly transforming the liquid into a dry condition. This method results in almost no ink absorption on the paper and very little solvent evaporation. What does this entail, then? It implies it is possible to print on almost any surface and substance! That alone is a significant benefit.

UV dries immediately upon touch, so they don't smear or smudge. Unlike traditional printing, the best thing is that you are not required to wait several days for the task to dry.

Why Is UV Printing More Advanced Now?

In addition to making printers more advanced, using UV ink paves the path for improved printing methods and practices overall because it requires less energy to cure the ink. It is a substantially more environmentally friendly choice because it not only optimizes your energy consumption but also doesn't discharge solvents into the atmosphere.

Ink cures quicker with UV printing, allowing companies to produce more quickly without sacrificing quality. Since no solvents are involved, the product won't deteriorate with time, making it ideal for long-lasting projects. When UV Printing Makes the Most Sense

1. When You Have To Print Quickly

Since UV ink may harden as soon as it touches the paper and traditional printing requires an evaporation process, UV printing is the best option for urgent jobs because it has a quick turnaround time.

2. When You Want A Particular Look

UV ink can print various images without the worry of smudging and dries quickly. A UV coating can reduce abrasions, ensuring that projects requiring sharp graphics or a silky finish turn out flawlessly.

In addition to increasing production efficiency, which results in more being produced in less time, the method also lowers rejection rates due to improved quality.

Since wet ink droplets are expelled instead of dry ones, there is no smearing or wiping off, and since drying takes almost no time at all, there is no degradation of coating thickness or size due to evaporation. 

Have you ever thought about the tiny microbes hidden from the naked eye that can wreak havoc on our health? From harmful viruses and bacteria to mold and allergens, these microorganisms can threaten our well-being. Fortunately, various methods of disinfection can help us eliminate these unwanted guests. One of the most effective and eco-friendly options is UV disinfection. By using ultraviolet light to destroy the DNA of microorganisms, UV disinfection can provide a high level of protection against a wide range of pathogens. In this article, we'll explore some of the key advantages of UV disinfection and how it can benefit your health and the environment. Please read on!

Highly effective against a range of pathogens

UV disinfection eliminates many pathogens, including viruses, bacteria, and mold. UV radiation damages the DNA and RNA of these microorganisms, rendering them unable to replicate and causing them to die. UV disinfection can be used in various applications, from air disinfection in HVAC systems and hospitals to UV water disinfection in homes and municipalities.

Advances in technology have made UV disinfection more accessible and efficient, with UV LED modules and diodes providing a cost-effective and long-lasting solution.

Furthermore, UV disinfection systems are simple, with many models featuring automatic shut-off and start-up capabilities. With the advent of UV LED modules and diodes, UV disinfection systems have become even more user-friendly and energy-efficient.

Safe for humans and animals

UV disinfection is a safe method of disinfection for humans and animals. Unlike chemical disinfection methods that can leave behind harmful residues, UV disinfection produces no toxic byproducts and does not pose a chemical exposure or ingestion risk.

While direct exposure to UV radiation can harm human skin and eyes, UV disinfection systems are designed to minimize the risk of exposure through proper shielding and safety features.

UV disinfection is commonly used in healthcare facilities and food processing plants where human and animal exposure is a concern.

Does not alter the taste, odor, or pH of water or air

One of the key advantages of UV disinfection is that it does not alter the taste, odor, or pH of water or air. Unlike chemical disinfection methods that can leave behind unpleasant tastes and odors, UV disinfection only affects the DNA of microorganisms, leaving the water's or air's natural properties intact.

This makes UV disinfection a preferred method of water treatment in industries such as beverage and food processing, where taste and odor are critical factors.

UV disinfection can also be used for air disinfection without altering the air quality or pH.

Compatible with other water treatment methods

UV disinfection is compatible with other water treatment methods and can be used in conjunction with them to provide an even more comprehensive approach to pathogen control. Some of how UV disinfection can be used in combination with other methods include:

· Chlorination: UV disinfection can be a post-treatment step to remove residual chlorine and ensure complete pathogen control.

· Filtration: UV disinfection can be used as a final step after filtration to eliminate any remaining microorganisms.

· Reverse osmosis: UV disinfection can be used to disinfect the permeate after the reverse osmosis process.

· Ozonation: UV disinfection can break down any residual ozone after ozonation.

By combining UV disinfection with other water treatment methods, you can achieve a higher level of pathogen control and ensure the safety and quality of your water supply.

Reduces the risk of infection and disease transmission
