LED Lamp Bead Packaging Process Analysis

First, the high -quality light -level diode brand Tianhui Optoelectronics Technology Analysis of the existing existing packaging methods and the application field of LED lamp beads is the earliest, which is used to produce a single LED lamp bead packaging device. It is suitable for instrumental indicators, urban lighting projects, advertising screens, barriers, traffic indicators, and some products and fields that are currently commonly used in my country. Patch LED lamp bead packaging (SMD) is a kind of non -lead packaging, small and thin, which is very suitable for the keyboard display lighting of the mobile phone, the backlight of the TV, and the electronic products that require lighting or indications. In recent years It develops in the direction of large size and high power, a piece of three or four LED chips in a patch, which can be used for assembly lighting products. The module packaging is also a multi -chip with LED lamp bead packaging. On the aluminum or aluminum nitride substrate, dozens of or hundreds of LED lamp chips are encapsulated on the aluminum or aluminum nitride substrate. It is a mixed type, that is, there are multiple chips in series, and there are several parallel connection. This packaging is mainly to expand power, for lighting products. Due to the high density of the packaging, the heat generated during the application is large, and the heat dissipation is the primary problem to solve the application. The device produced by the above packaging method is used in the production of lighting fixtures. It has a common characteristic: the number of thermal resistance is large, it is difficult to produce high -quality lighting fixtures, and the connection processing requirements of the module itself and the radiator are relatively high. At present, all packaging methods are to mix yellow fluorescent powder (YAG) and epoxy resin evenly on different columns, and directly click on the blue -light LED lamp bead packaging chip. The advantage of this common practice is to save materials. The disadvantage is that it is not conducive to heat dissipation and fluorescent powder. Because epoxy resin and fluorescent powder are not good -conducting materials, and the entire chip wrapped in the entire chip will affect heat dissipation. This method is obviously not the best solution for making LED lighting fixtures. At present, the high -power chip produced abroad, the white -light chip above 0.5 watts is painted on a blue light chip on a even layer of evenly YAG fluorescent powder. There is no fluorescent powder in the cushion. This method can improve the light effect than the commonly used methods, so it is generally used abroad. ) As long as this white -ray chip is welded on the designed circuit board when packaging, it saves the process of applying fluorescent powder. It brings convenience to lamp manufacturers, but currently domestic suppliers of domestic production chips cannot produce such LED white light chips in large quantities. my country is the country that develops LED lantern street lights earlier. It is currently good in China because the country attaches importance to the "low -carbon economy". In 2009, my country implemented 10,000 LED street lights. The feasibility of street lights is based on street light applications, while foreign countries (Osram, Japan Asia, Samsung and other companies) take indoor lighting as a breakthrough. As far as our country is concerned, it is caused by the national conditions from LED street lighting. The reason is that my country's national income is low, and the cost of LED indoor lighting is higher. The use of LED street lights is the government's silver, and the high -power LED lamp bead street light production enterprise is justified. In fact, the working conditions of the LED street lights are more harsh than the indoor LED lamp bead lighting fixture, and the requirements are higher. If the quality is clear (heat dissipation, service life, color rendering, reliability, etc.), then then do the indoor LED lighting lights. It's easier. At present, LED giants abroad are launching a large number of hundreds of or even thousands of LED indoor lighting fixtures. But the packaging methods they use are mentioned earlier. The only Philips company, which makes fluorescent powder apply on the LED lampshade, and is rated as one of the most creative LED lighting products in 2009. The author believes that all LED lighting fixtures should be manufactured by multi -chip packaging and module packaging (module packaging is a high -density multi -chip package), and it is best to be packaged directly on the main body of the lamps. The number of roads is the least, and you can get better heat dissipation effects. Or make a line body with copper foil on the main body of the lamp, and its heat resistance is also low. The power of LED lighting is at least a few watts, so it is used by multiple chips. New methods and craftsmanship. Using multiple encapsulated LED lamp bead packaging devices to assemble LED lamps, it is difficult to create high -quality and highly reliable LED lamps. Technical personnel who want to engage in LED lamps can understand this. Second, the high -grade light -level diode brand Tianhui photoelectric technology analysis of the innovative module of the fluorescent powder coating process LED lamp beads packaged the fluorescent powder. At present, the fluorescent powder is directly applied to the chip. The fluorescence powder of the group is still the same, but different modules may appear in large quantities of production. The better way is to use LED fluorescent powder thin films or membranes. , Good consistency, LED lights are packaged by multi -chip, mixed with the light emitted, transformed by fluorescent powder or membranes to white light, the color difference can be eliminated. The requirements for the film and membranes are: 1 can pass through the light, between 0.1 ---- 0.5mm, the fluorescent powder is uniform, the appearance is flat. 2 The light conversion efficiency should be high, good stability, long life, good anti -aging. 3 It can be made into a sheet and a pieceless basis, and it can be made into a thin piece. The requirements for the foundation are colorless transparent anti -aging. 4 It is convenient for processing and forming, the size is arbitrarily cut, and the cost is low. Another method is to mix the fluorescent powder and transparent plastic proportion, directly produce a lampshade with fluorescent powder through injection molding machines and molds, and convert the blue light from the lampshade to white light. This is more troubled and convenient. Because the lampshade is converted to mixed blue light, the white light output has no color difference, and the light is softer. Third, in order to better solve the problem of LED lamp bead packaging heat dissipation, high -grade light emitting diode brand TIANHUI Optoelectronics Technology said: should be considered and encapsulated by the lamps, and the heat dissipation tablets for packaging the heat dissipation of LED lamp beads should be made into a whole, which effectively reduces the effect. The number of thermal blocks, this is a very effective and effective way to increase the heat dissipation of the lamp. At present, the LED lamp beads on the market do not have a heat sink. Such lamps cannot be high -power and high -quality and long life. The correct product design should consider the heat sink together. Industrialized production is the radiator of the LED lamp beads sunlight, squeezing out the aluminum profile of the semi -circular winged piece with a mold, and then cut the length of the required length according to the power size, and then Making aluminum -based copper foil lines, fix the chip on the copper foil, connect the gold wire or use the help machine to help. Such lamps have good heat dissipation effects, only two thermal resistances, one to two -way heat resistance than commonly used packaging methods, effectively reducing the temperature of the chip, which can effectively improve the quality and life of LED fluorescent lamps. Another method is to design sudden strips on aluminum profiles. Many rectangles are milling as needed. In the use of ordinary (0.8-1.0mm thick) PCB line boards according to the rectangular open -length square hole of aluminum profiles, paste the PCB line board or paste or paste or paste it or Riveting on aluminum profiles, the LED chip is fixed on the rectangular tap on the aluminum profile, and then connects the line on the PCB board with the gold wire. This production process is the best, the heat resistance is only one, and the heat dissipation effect is the best. Manufacturers who produce LED lamps should give priority to this solution. Secondly, the method of making copper foil lines on aluminum profiles. Only such an innovation can effectively solve the heat dissipation problem of LED lamp beads packaging long strip lamps, and can improve the quality and life of LED lamp beads packaging.

Deep Ultraviolet Disinfection Sterilization How To Use The Car?
Deep Ultraviolet Disinfection Sterilization How To Use The Car?
UV cleaning of surfaces and air has become more prevalent from outside medical settings with the advent of COVID-19. Several airlines are now employing Air Disinfectionto eliminate any bacteria that might be present in the HVAC system and on flight electronics panels. Additionally, a broad variety of low-output UVC disinfection tools have been offered for use in restrooms, interiors of personal and commercial vehicles, and other tiny places. However, there are several difficulties when employing UV-C germicidal irradiation to clean the inside of vehicles. The cab of a semi-truck or the interior of an automobile may require more than just cheap UVC equipment. Can UVC Clean The Inside Of Cars And Trucks? The first concern is if UVC Air Disinfectioncan clean the interior of automobiles and trucks in any way. Thankfully, the solution to this is simple. No bacterium has yet been identified that is resistant to ultraviolet irradiation. Therefore UVC light wouldn't encounter any further obstacles when it came to neutralizing hazardous pathogens in a vehicle. To clean the air and surfaces in cars, UVC Air Disinfectiondevices can be utilized. But there may be difficulties in these regions. Problems with UVC Use in Fabrics for Vehicle Interiors The CDC suggests using a UV radiation of 1,000 MJ/cm2 to sterilize N95 masks, which is an extremely high UV exposure. It is far greater than the UV dose necessary to render SARS-cov-2, the virus causes COVID-19, inactive in 99.999%, and the UV dose necessary to render MRSA, C. Diff, and other infections inactive. Due to the nature of N95 masks, which are constructed of fabric with patterns and shadows that UVCAir Disinfectionmay not infiltrate well or will create locations for germs to hide in shadows, the CDC advises using this much UVC. This problem will affect almost everything fabric interiors of vehicles and trucks. Leather seats and cushions won't experience the issue to the same extent as those made of fabric, but textiles will need more UV because of the light's poor light penetration. Shaded Regions Large sections of the vehicle's interior may not be covered if only one UVCAir Disinfectiondevice is used. Where the sunlight does not shine, shadows may be cast by seats, the steering column, the center console, and other items.UV sanitation will be minimal in areas without UVC Air Disinfectionlight. Central heating and cooling for vehicles UVC Air conditioning units make a ton of sense and could be the most efficient use of UVC for residential and commercial buildings. They work in tandem with filters to eliminate large particles and neutralize tiny microorganisms as the air circulates through the ducts. There isn't much space to install a UVC HVAC system in a commercial or personal vehicle, and we haven't seen any readily available kits from vendors. This means UVC Air Disinfectionof an automobile's interior should only be done between travels. As a result, UVC is a very limited option for cars in use, and long-term far-UV exposure has not yet been shown to be safe for all varieties of human skin and eyes. Ideal Techniques Clean Surfaces First UVC is most efficient when combined with other hygienic procedures. Large particles and bacteria can be removed from surfaces by wiping them down with a cleaning solution. Smaller particles may also be aerosolized, which will facilitate UVC action. Evenly Place Several UVC Units No matter where UVC devices are installed in the car, there may be various areas of shade. Therefore it may be more sensible to employ many UVC devices than to boost the power of a single lamp. Additionally, it can store UVC equipment near cushions and seats that require high UV dosages.

Additionally, it can store UVC equipment near cushions and seats that require high UV dosages. Portables for Problem Areas Finally, handheld UVC devices can be utilized to access extremely challenging locations with permanent UVC equipment. This might be in places where UV-led modules wouldn't typically penetrate with the devices, including behind seats or in the glove box. Handheld UV devices don't make much sense as a primary option due to the enormous surface area inside a car or truck and the amount of time needed for UV-C to be effective, but they can be a useful addition.

Development Of UV Leds Under The Epidemic
Development Of UV Leds Under The Epidemic
Health-related and waterborne infections cost the world billions of dollars annually and thousands of lives yearly. One important preventive step is sterilization, which can be accomplished using various methods, including ultraviolet (UV) light irradiation. Since proper sterilizing procedures can stop the transmission of infectious diseases, this requirement has become more urgent because of the worldwide coronavirus epidemic. Compared to semiconductor light sources, current sources like mercury bulbs are bulky, hazardous, and have fewer application options. What Are UV LEDs? UV-LEDs are LEDs that produce UV rays with wavelengths of 400 nm or less. They are separated into deep-ultraviolet LEDs (DUV-LEDs), which have an emission wavelength of around 200-320 nm, and near-ultraviolet light-emitting diodes (NUV-LEDs), which have an emission wavelength of about 320-400 nm. UV-LEDs are promising candidates for several applications, including the replacement of UV lamps, fluorescence light sources for displays and lighting, good lighting sources for microscopes and exposure equipment, light sources for chemical excitation 4used in biotechnology, medicine, and resin curing, excitation light sources for spectroscopy used in currency notes identification, DNA chips, and environmental monitoring, and sanitary light sources for disinfection and sterilization. Creation Of Uv Leds Even in an ongoing epidemic, disinfecting fomites is a crucial public health practice in halting the transmission of many infectious diseases. There is undoubtedly interest in creating technology that would allow for regular, high-throughput disinfection, especially in highly visited public venues, given the recent knowledge of the close role contact and indoor crowding play in virus transmission. Despite their effectiveness, the active chemicals in traditional chemical disinfectants in clinical and laboratory settings pose climate, public health, and infrastructure risks that make their widespread deployment difficult. Additionally, the effectiveness of chemical disinfectants can vary depending on the user and how carefully they follow repeatable cleaning procedures. As an alternative, ultraviolet (UV) radiation has been widely utilized to inactivate numerous microorganisms, including viruses. Ultraviolet light can be automated to produce a repeatable germicidal dose. The introduction of uv led diode gives the very same level of decontamination as the traditional mercury lamps, but with several advantages, including simplicity of retrofit in a variety of usual overhead light sources, with enhanced disinfection capabilities. The effectiveness of UV for cleaning is shown by its straightforward mode of operation. While neighboring thymine bases (or uracil bases in the case of RNA) suffer dimerization, which disrupts the structure of nucleotide sequences and creates "roadblocks" in genome replication, adjacent nucleotide bases in DNA and RNA uniquely absorb UV photons Researchers demonstrated the antiviral effectiveness of a uv led module by inactivating two viruses: the seasonal human Coronavirus 229E (hCoV-229E) and the immunodeficiency virus type 1 (HIV-1). Researchers demonstrate significant reductions in viral replication within seconds after UV-LED exposure by simulating common environmental instances of virus scattering (e.g., sneeze, cough, blood droplets) utilizing droplet dispersal approaches. Our research contributes to the body of knowledge on using UV-LEDs to sanitize high-contact public places. UV-LEDs represent an extra, very effective layer of defense against pathogen spread because they are inexpensive and simple to install into a range of existing light fixtures, especially during an ongoing respiratory infections pandemic. Requirements For UV-LEDs Nine 275 nm LEDs in a 3 3 array and twenty 380 nm LEDs in a 4 5 array comprised the two sets of UV-LEDs that were supplied. The distance between the LEDs and the exposed sample was around 5 cm, and the UV light output from each array ranged from 0.4 to 0.6 mW/cm2. The highest radiation duration was 30 seconds, and the combined arrays supplied a total dose to the radioactive samples ranging from 8 mJ/cm2 to 20 mJ/cm2. The device's entire lighted area was around 10 cm by 20 cm, or 200 cm2, significantly greater than the irradiated sample, and it received a total aquifer dose of 1.6 J to 4 J. Results To The Research For the Development Of UV LED Under Epidemic uv led modulewere shown in these studies to be effective at inactivating UV-resistant bacteria, HIV-1, and the human Coronavirus 229E. In the case of the human coronavirus, we saw a reduction in viral replication of up to 5.8-Log. Since RNA damage is the specific mechanism of deletion by UV irradiation and how-229E is an RNA virus, researchers predict a similar reduction in infectiousness after exposure to UV. However, they did not directly assess if this reduction in hCoV-229E replication corresponds with a similar reduction in infectivity. Researchers warn that our results could be directly applied to assess the efficacy in sanitizing non-enveloped viruses because they are typically more resilient to UV than enveloped viruses. In this study, investigations indicate that our selected virus designs were all enveloped viruses, selected to assess any possible differences in UV receptivity due to viral genome length. The inactivation of B. pumilus spores, which are renowned for possessing a high level of UV resilience, was demonstrated in our trials. Researchers say this may be the first proof that non-enveloped viruses can be inactivated by UV light. It has been proposed to use B. pumilus spores as a stand-in for testing the inactivation of the non-enveloped human rotavirus by UV radiation. https://www.tianhui-led.com/uv-led-diode.html Where Can You Purchase Your UV LED From? With a complete production run, consistent quality and dependability, and affordable costs, Tianhui Electronicshas been working in the UV LED Solutionmarket. UVLed manufacturerscome in UVA, UVB, and UVC wavelengths. Based on diverse UV applications, numerous types of uv led diodeare available, such as UV LEDmosquito traps, UV LEDsterilization bottles, and vehicle-mounted UV LEDair purifiers. Modern UV LED Solutionis utilized for airborne pathogen eradication and photocatalytic purification in automotive UV LEDair purifiers. With cutting-edge UVC LED sterilization technology, which is non-toxic and mercury-free, without radiation or odor, the UV sterilization rate for UVC LED disinfecting cups thermally can reach as high as 99%. When used in a UV LEDmosquito trap, UV LEDs with the maximum optical output may efficiently attract mosquitoes over a larger area. They also produce CO2 through a photocatalytic reaction with coated TiO2 on the inner side of the top roof.

[Reduce Risk] Manufacturers Help You Find a Reasonable UVLED Curing Function
As long as friends who know the principle of UV ultraviolet solidification a little know, the deep solidification of ultraviolet radiation, the main condition is that the molecules must absorb sufficient energy to become an inspiration molecule, decompose into free radicals or ions, so that the unsaturated organic matter is aggregated and connected. Chemical reactions such as branches and cross -linking to achieve the purpose of solidifying. Among them, the UVLED energy of the UV glue or UV ink in the UV ink exceeds or less than the energy required, it will be difficult to have the ideal solidification effect. 1. The UVLED energy required by the Knowing Optical Discovering agent is to ensure thorough solidification, the energy scientific and reasonable energy provided by the supply is normal than the energy it needs. 2. I do not know the UVLED energy required by the light caused by the light cause, and the supply is the supply blindly. Methods not only waste energy, but also cause negative effects of excessive solidification, such as explosion gathering, anti -aggressive reactions, etc. For some glue, it may even cause yellow change or fission problems. 3.
