As the traditional LED industry enters a mature saturation period, manufacturers have adjusted their development strategies, and instead expanded segments such as automotive lighting, plant lighting, UV LED, IR LED, as well as small spacing, mini/micro LED and other new display fields. Among them, in the field of UV LED, although many manufacturers have long -term layout, the UV LED product market has not received high acceptance in the past. Therefore, the UV LED industry has been in its infancy, especially the UVC LEDs with relatively high technical difficulties and prices. However, since the new type of coronary virus pneumonia has spread globally, consumers' awareness of sterilization and disinfection has increased rapidly, and the demand for UVC LED series products has increased, promoting the global multi -party forces to invest in the research and development of UVC LED technology, which has also spawned various kinds of various kinds Products, how do these products meet the relevant requirements? In fact, many factors need to be considered in the selection of reliable UVC LED products, such as: different doses and irradiation time for different viruses and bacteria to achieve disinfection and sterilization effect. From the perspective of product production, there are many considerations from the extension chip to the packaging to the finished product. This time, LEDINSIDE has revealed the required materials, craftsmanship, technical problems and development trends required for the UVC LED packaging session to better understand the UVC LED packaging product. UVC LED encapsulation forms, craftsmanship, and material selection are special. At present, UVC LED packaging has three forms: organic packaging, semi -inorganic packaging (also known as“Near -inorganic packaging”) And all -round packaging. Organic packaging uses organic materials such as silicone, silicon resin or epoxy resin, mainly including LAMP, SMD, ceramic MOLDING and other products. The overall technology is relatively mature, but the anti -ultraviolet performance needs to be further improved. Half -inorganic packaging (also known as“Near -inorganic packaging”) Use organic silicon materials with glass and other inorganic materials. The whole inorganic packaging avoids the use of organic materials throughout the process. The combination of lens and substrates is achieved by laser welding, wave welding, and resistive welding. Effectively improve the stability and reliability of UVC LED devices. It is understood that domestic manufacturers such as Guoxing Optoelectronics, Mustang Shen Zi Zi, Hongli Bingyi, and Huayinxin have all developed the UVC LED products of all -inorganic packaging. At present, the semi -inorganic packaging product is still the mainstream of the domestic market. It is mainly composed of a ceramic stent and quartz glass with a cup. It is placed by coating the anti -ultraviolet glue in the edge area of the ceramic substrate to achieve the lens. Specifically, dot glue at the top or steps of the cup, and then cover the quartz glass for curing and bonding. In terms of materials, UVC LED packaging is different from ordinary LED. First of all, the choice of quartz glass is because quartz is inorganic, will not be affected by ultraviolet rays, and the high rate of quartz glass on the UVC band is high. Secondly, in terms of heat dissipation substrates, due to the low efficiency of UVC LED photoelectric conversion, most of them are converted into heat, so the aluminum nitride heat sink substrate with high heating rate is generally used. In addition, UVC has a bad effect on glue. Therefore, the requirements for UV resistance in the glasses of bonding glass and brackets are higher than that of ordinary LED packaging. It is also worth noting that some manufacturers use aluminum oxide heat dissipation substrates. Both aluminum nitride and aluminum oxide substrates belong to the ceramic substrate. The main difference between the two is that the heating rate of aluminum nitride is much higher than alumina. Among them, aluminum nitride thermal conductivity is generally about 140W/mk-170W/mk, while aluminum oxide thermal conductivity is only about 30w/mk. Alumina ceramics are generally white, low thermal conductivity, usually used for low -power products. However, alumina ceramics is large, and it is easier to crack than aluminum nitride. Therefore, it is prone to collapse in the process of cutting. Aluminum nitride ceramics generally presents gray -black, has a high heating rate, and is usually used for high -power products. In addition, there are also alumina ceramics doped on the market, which are also gray -black, but the heating rate is lower. The quality of thermal management and gas -density affects the quality of UVC LED packaging products UVC LED packaging products. The quality of the quality of the product and the influence of gas tightness. These two aspects are also technical difficulties in the packaging link. Among them, thermal management directly affects the life of UVC LED packaging products, while gas tightness determines its reliability to a large extent. UVC LED is sensitive to heat, its external quantum efficiency (EQE) is low, and only a small part of the electrical energy is converted into light, and most of the electrical energy is converted into heat, which directly affects the service life of the chip. In view of this, at this stage, many products are based on the scheme of pouring chips with high heat -conducting aluminum nitride substrates. Aluminum nitride has excellent thermal conductivity, can tolerate the aging of UV light sources itself, and meets the needs of UVC LED high -heat management. In addition to materials, the packaging process is also the influencing factor of heat management. The packaging process is mainly reflected in solid crystal technology, including silver pulp welding, tin paste welding, and gold tin co -crystal welding. Although silver pulp welding is good, it is easy to cause silver migration, resulting in the failure of the device. As for the welding of tin paste, because the melting point of the tin paste is only about 220 degrees, after the device patch, the phenomenon of re -fusion will occur again. Golden tin co -crystal welding is mainly used for co -crystal welding through the welding agent, which can effectively improve the binding strength and thermal conductivity of the chip and the substrate. In contrast. Therefore, the gold tin co -welding method is used on the market. In the welding process, it mainly involves the problem of welding hollow rate. Welding empty hole refers to the defects formed during the welding process of LED chips and substrates. It presents a state of empty appearance in appearance. It is an important indicator affecting heat dissipation. The lower the welding empty hole, the better the heat dissipation effect, the longer the product life, the better the quality, the better the quality. It is understood that the inorganic packaging technology of Huayin core uses inert gas and restore gas mixed protection environment to perform hot pressure co -crystal welding of the chip to further increase the efficiency of electrical connection, while reducing the hollow rate, stable LED knot temperature. Guoxing Optoelectronics's advantages and characteristics in common crystal welding technology are very prominent. The company has 10 years of common crystal technology precipitation, and the reflux common crystal vacuum rate is basically controlled within 10%, which is greatly lower than similar products on the market on the market. According to reports, in terms of reducing welding hollow rates, the company has formed a relatively leading and perfect process technology. At present, the overall empty hole area of its UVC LED products is below 10%, and the largest empty hole area of a single hole is below 2%. Compared with the hollow rate of the same type of product in the market 15%-30%, the heat dissipation effect is excellent, the product life is long, the product item products Better control. In terms of reliability, the form of packaging is one of the factors, but the key is. In the form of semi -inorganic packaging, glass lens and cup ceramic substrates will form a closed cavity through glue connection. Because the closed cavity cannot be vacuum, when the glue is heated, the air in the cavity is vulnerable to heat and spilling, forming a bubble, and a gas channel formed in severe cases. At this time, external water vapor and impurities can enter the product through air bubbles and gas channels, which cause pollution to chip and substrates and other materials, which seriously affects the gas tightness of the product, thereby affecting the light and reliability. It can be seen that the impact of gas tightness has a great impact on the quality of UVC LED packaging, and process processing technology is very critical. It is worth mentioning that by optimizing the surface treatment and continuous packaging and curing technology of the substrate, the National Star Optoelectronics has also formed a complete packaging process solution, which can effectively reduce the closed cavity air, realize the zero air bubble and zero of the UVC LED device, and zero zero. Air passage. UVC packaging pattern: semi -inorganic packaging is the main, and the whole inorganic packaging is supplemented by thermal management and gas tightness. UV resistance is also one of the technical difficulties of UVC LED packaging. In order to improve the anti -ultraviolet performance of the product, many manufacturers have stepped up the development of all -inorganic packaging products. For example, Guoxing Optoelectronics has developed high -cost all -inorganic UVC devices for special products, and the cost advantage is obvious. At the same time, the company is also jointly developing anti -UVC fluoropic resin packaging material products with material manufacturers. The product has the characteristics of high temperature resistance, larger current, and anti -UV radiation. Jingneng Optoelectronics's UVC LED products are mainly high -power ceramics packaging. Ceramic materials are packaged, and product heat dissipation performance is good. Hongli Zhihui also continues to carry out research on inorganic packaging technology, which aims to develop UVC LED products with high light power, high reliability, long life, and cost -effectiveness. In terms of UVC LED packaging future development trend, Guoxing Optoelectronics believes that the domestic market will still be mainly encapsulated in the next year or two, supplemented by the whole inorganic packaging, but as organic materials have improved and innovated by UV resistance and innovation , Organic encapsulation such as fluorine resin will likely occupy a part of the market share. Since the beginning of this year, different technical fields of UVC LED have achieved certain breakthroughs, conveying signals that the industry is booming. Although, due to high cost and low light effects, the current UVC LED products cannot completely replace medical sterilization UV mercury lamps. But Guoxing Optoelectronics believes that with the advancement of technology, I believe that UVC LED will slowly enter this market soon. Moreover, due to small volume and simple design, UVC LED is currently in the field of mobile killing and small space sterilization. Compared with mercury lamps, it has certain advantages. According to LEDINSIDE, from the current market application, UVC LED has begun to be applied to surface sterilization (carried sterilization products, sterilization lamps, maternal and infant products), water sterilization and air purification

Technology Co., Ltd. (13 industry experience in the production field of LED lamp beads). For the convenience of customers' choice of color temperature, the engineering department can provide customers with solutions. Technology Co., Ltd. can provide solutions for LED lamp bead manufacturers. The company's color temperature knowledge is popular: Because most of the light emitted by the light sources is collectively referred to as white light, the color surface temperature or related color temperature of the light source is used to indicate its light The degree of color is relatively white. Black Body Locus on the CIE color seat shows the process of black body red -orange red -yellow -white -white -white -white -white -white -white. The black body is warm to the same temperature when the light source or close to the light color. It is defined as the related color temperature of the light source, which is called the color temperature, and the absolute temperature K (Kelvin or Kaishi temperature) is the unit (K = 273.15)). Therefore, when the black body is heated to red, the temperature is about 527 C, which is 800K, and other temperatures affect the change of light color. The more blue the light color, the higher the color temperature; the lower the color temperature, the lower the color. The light color of the painting in the day also changes with time: 40 minutes after sunrise, the light color is yellow, and the color temperature is 3,000K; the sun is white at noon, rising to 4,800-5, 800K; ; Before sunset, the light color is red, and the color temperature drops to paper 2,200K. The related color temperature of other light sources is in fact when the related color temperature is in fact, when the black body radiation is close to the light color, the value of the light source of the light source is not a precise color contrast. There may still be a little difference in the appearance of light color. It can not understand the color rendering ability of the light source to the object by the color temperature, or the reproduction of the color of the object under this light source. Related color temperature of different light sources environment North Qing Kong 8000-8500K Yinyin 6500-7500K Summer Non-Summer Sunshine 5500K metal halide lamp 4000-4600K Afternoon daylight 4000K Cold Camp Light 4000-5000K High-pressure mercury lamp 3450-3750k warm color camp light 250000 -3000K halogen lamp 3000K tungsten wire lamp 2700K high-pressure sodium lamp 1950-2250K candlelight 2000K light sources are different, and the light color is different. There is a stable atmosphere and warm feeling below 3300K; the color temperature is 3000--5000K is the intermediate color temperature, which has a refreshing feeling; the color temperature is above 5000K. Different light colors of different light sources form the best environment. Color temperature is a feeling of human eyes on light or white reflection. This is a comprehensive and complex factors of physics. Body and psychology. The color temperature can be changed in an artificial way in the TV (luminous body) or photography (reflector). For example, we use 3200K hot light (3200K) on photography, but we add red filter on the camera to the lens. Filter through a little red light to make the photo look a bit lower; the same reason, we can also reduce a little red on TV (but reduce too much more, it will affect the normal red performance). The preference in color temperature is dependent on person, which is related to our daily view of the scenery. For example, people who are close to the equator, the average color temperature seen daily is 11000K (8000K (dusk) 17000K (noon)), at noon), So I prefer high -color temperature (it looks more real). On the contrary, people with high latitudes (average color temperature of about 6000K) prefer low -color temperature (5600K or 6500K), that is, if you use a high high The color temperature TV shows the landscape of the Arctic, and it seems to be biased; on the contrary, if you use a low -color temperature TV to watch the subtropical style, you will feel a bit red. How is the color temperature of the TV or the display defined? Because the average color temperature of the year and four seasons in China is between 8000K and 9500K, the production of the TV station on the show is based on the color temperature of the audience to 9300K. However, because of the usual color temperature and the differences in us, in Europe and the United States, based on the average color temperature of the year and four seasons, it is about 6000K for reference. Therefore, when we watch those foreign films, we will find that 5600K 6500K is most suitable for watching viewing. Of course, this difference makes us feel that it feels warm and warm when I see the computer or TV screen of European and American TVs fiercely. It is the person with colorful and black eyes looking at 9300K is white, but the blue -eyed people look at it with blue 6500K blue eyes. This article comes from LED lamp bead manufacturers.

At present, the luminous body of the UVLED curing machine on the market is ultraviolet UVLED lamp beads. The UVLED curing light is composed of one or more Ingan quantum traps in a thin GAN sandwich structure, and the source area formed is. By changing the relative proportion of Inn-GAN in the Ingan quantum trap, the launch wavelength can be changed from purple light to other light. Algan can be used to make the cover layer and quantum trap layer in UVLED by changing the ALN ratio, but the efficiency and maturity of these devices are poor. If there is a source quantum trap layer is GAN, which is relative to Ingan or Algan alloy, the spectral range of the device emitted is 350 370nm. When a short electronic pulse at the blue inflection diode pump, ultraviolet radiation is generated. Aluminum -containing nitrogen, especially Algan and Algainn can make short -wavelength devices, obtain a series of wavelength UVLED. Most of the domestic manufacturers still use traditional ultraviolet mercury lamps to work. However, due to the characteristics of UVLED long life and no radiation, its application is also becoming more widely widely used. Zhuhai Tianhui Electronic Co., LTD. is a company engaged in LEDUV irradiation equipment. After years of accumulation, it has a very rich LEDUV irradiation point light source and wire surface light source equipment types. It can also customize various equipment according to customer needs according to customer needs.

LED lamp beads have many strengths such as energy conservation and environmental protection. Following the reduction of LED lamps quotation, these years, LED lamps have slowly entered the vast home lighting and lighting market. And more and more wide. So, what are these infrared LED lamp beads on the lamps? First of all, in addition to the primary use of infrared LED lamp beads on the scene lighting shopping mall, including: construction decoration, interior decoration, tourist attractions and other lamps, it can also be used on the primary construction, big streets, business centers, famous monuments, bridges, communities, yards , Lawn, home, leisure and entertainment, decoration lighting fixtures, and commercial lighting lamps that are integrated and advertising. Secondly, the infrared LED lamp beads are first used on the car lamps. Car shopping malls are infrared LED lamp beads using fast -developed lamp shopping malls. They are mainly used in the instrument panel, air conditioning, audio and other indicators and internal reading lights. Wait. Again, infrared LED lamp beads also have many use in the backlight shopping mall. For example, infrared LED lamp beads have been used in many fields such as mobile phones, computers, handheld electronic products, cars, aircraft dashboards and other fields. In the end, infrared LED lamp beads also have many use in traffic lamp malls. It is precisely because infrared LED lamp beads red, yellow, and green LED have high brightness, long life, and power saving. The LED light source has the characteristics of seismic resistance, weather resistance, good sealing, low heat radiation, small volume, and easy to carry. It can be widely used in special operations such as explosion -proof, field operations, mines, military operations, etc. In the process of the curing process of deep ultraviolet LED lamp beads, the oxygen resistance aggregation has always been confused by everyone: when the light is curing in the air, the oxygen blocking effect often causes the bottom layer of the coating. Oxygen blocking can cause the surface layer of the coating to present a lot of oxidative structures such as hydroxyl, cymbal, and peroxy groups, and then affects the long -term stability of the coating, and may even affect the hardness, gloss and resistance of the paint film after curing. Function. Why? The basic state of the material is single -line, but the stability of O2 is three -line state. Therefore, it consumes free radicals with the aggregation response competition of free radicals. Because the vast majority of optical curing technology is performed in the air environment, and the primary application is data such as coatings and inks with a large appearance/volume ratio, O2 has a free radical polymerization response to the free radical polymerization of optical solid data. Concentration. Especially when the thickness of the coating film is thin, the concentration of oxygen in the oily organic system is generally less than or equal to 2 10-3 mol/L. Not only does the dissolved oxygen molecule in the formula obstruct the aggregation, in the process of light, follow the oxygen in the solidification system. The consumption of the molecule, the oxygen in the appearance of the coating air can also be scattered into the coating agile, continuously obstructing the aggregation. The oxygen concentration of the system Chinese dissolved in China is very low, which is easier to consume. Regarding the closing system, the process of primary activity free radicals consuming oxygen is basically equivalent to the aggregate induction period. Relatively speaking, oxygen from the outside world to the inside of the coating is the primary cause of obstruction of aggregation. Oxygen blocking also occurs simply in the superficial layer or all of the thin coating, because in these areas, the oxygen molecules in the environment are more simply.

The characteristics of infrared LED lamp beads are similar to the shape of the general visible light LED lamp beads, but the infrared rays are issued. Its voltage is generally about 1.4V, and the working current is generally less than 20mA. In order to adapt to different working voltage, limited flow resistance in the circuit. When using infrared LED lamp beads to control the corresponding controlling device, the distance between its control is proportional to the launch power. In order to increase the control distance of infrared rays, the infrared LED launch tube is working in the pulse state, because the effective transmission distance of the pulse light is proportional to the veins of the pulse. As long as you try to increase the peak IP, you can increase the transmission distance of infrared light. The method of improving IP is to reduce the pulse to the duty ratio, that is, the width T of the compressed pulse, the duty -duty duty cycle can also increase the launch distance of the low -power infrared light. Ordinary infrared light emitting diodes are divided into three categories: small power, medium power and high power. To make the infrared light emitting diode generate, just add a certain frequency pulse voltage to the drive tube. When infrared diode emitted infrared rays to control the controlled device, there are corresponding infrared conversion elements in the control device, such as infrared receiving diodes, infrared receiving heads, light -sensitive triode, etc. There are two ways to launch and receive infrared launch, namely direct and reflectives. Direct refers to the relative to the two ends of the launch and the controlled by the optical pipe and the receiving tube, and the middle phase is a certain distance in the middle; the reflection of the light pipe is tied together with the receiving tube. Usually the receiving tube is always no light, and only the infrared emitted by the luminous pipe only in the luminous pipes. When the light encounters a reflex, the receiving tube receives the infrared light returned from the reflection. Double -tube infrared launch circuit can increase the launch power and increase the distance of infrared launch. Specializing in the production of various types of LED lamp beads, we are all customized according to the needs of customer product needs, and according to the characteristics of infrared LED lamp beads, we can get a wider range of applications according to different wavelengths: 1. Wave length: 808nm, applicable to applicable In the pump light source of medical equipment, space light communication, infrared lighting, and solid laser; 2, wavelength: 830nm, suitable for automatic card swiping system on high -speed roads (the night vision system is best, you can see that there is a little red light on the tube core. , The effect is better than 850nm); 3, wavelength: 840nm, suitable for cameras and color change infrared waterproof; 4, wavelength: 850nm, suitable for cameras, digital photography, monitoring, building intercom, anti -theft alarm, infrared waterproof; 5 Wavelength: 870nm, suitable for cameras at the intersection of shopping malls and crossroads; 6. Palace: 940nm, suitable for remote control, such as the remote control of home appliances. Zhuhai Co., Ltd. is a professional LED lamp bead manufacturer with a number of national patents.
