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.

As the brightness increases and the price decreases, the market potential of the white light LED in the field of universal lighting is increasing. The use of white light LED in the general lighting industry will have a positive impact on the energy strategies and environmental protection strategies of the country or region. The white light L E d has a small volume, a plane packaging, or using multiple or multiple combinations according to the environment or condition, and has a low heat calor, long luminous life (more than 50,000 hours), not easy to break, extremely earthquake resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock resistance and extremely shock to resistance and volatile and extremely shock -resistant and extremely shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very shock -resistant and very resistant to shock. Patient resistance can be used in harmful conditions and other characteristics. The white light LED light emitting efficiency is high, so many metals such as power saving, heat -free radiation, non -containing mercury, no pollution and waste treatment problems, etc., are regarded as the star of tomorrow with the "green lighting source". Replace the mainstream incandescent bulbs and fluorescence (daily) lights currently for the lighting market. The development of the white light LED lighting industry will affect the energy and environmental protection strategies of a country and region. Therefore, various countries have supported the example of the LED semiconductor lighting industry as a major national development. The white light LED market is the most optimistic of the LED industry with strong market potential lighting sources in the LED industry. According to FROST & SULLIVAN's estimates, the global lighting light source market has climbed a stable growth rate of 5%per year; of which, white light LEDs are more likely to enter the incandescent bulb and fluorescent light market. These two products are the most popular civil lighting. The light source, the market potential of the white light LED in the future can be said to be quite huge. 1. The white light LED light -emitting principle white light LED lighting method is mainly divided into two types: single crystal type and polycrystalline type using LED light -emitting diodes. The first is a single crystal type, that is, a monochrome LED light -emitting diode and the corresponding fluorescent powder, just like the lighting method of the sunlight, using LED light -emitting diode. There are usually two ways. One way is that the blue light LED glowing diode stimulates yellow fluorescent powder to produce white light. The other is the ultraviolet light LED stimulating RGB three -wave long fluorescent powder to produce white light. Many manufacturers are mainly engaged in the research of white light LEDs. They usually start developing and mass production from Blu -ray LED. With the technology of Blu -ray LED technology, Baiguang LED is developed. However The lighting efficiency of the blue light LED is still insufficient. Many manufacturers began to develop in another direction to develop in the ultraviolet light LED. Blue light is better. And the method of UV LED and RGB three waves of fluorescent powder, the key technologies in high -efficiency fluorescence synthesis, that is, how to effectively attach fluorescent powder to a technology. The other is polycrystalline, even if two or more complementary 2 -color LED light -emitting diode or 3 primary LED light -emitting diode are mixed to form white light. The multi -crystalline type of white light is used, because the driving voltage, light output, temperature characteristics and life span of different colors of LED light -emitting diodes are different. The method of generating white light in the type of LED is complicated. Because of the large number of LED light -emitting diodes, the cost of polycrystalline LED is also high. If a single crystal type is used The design on the drive circuit will be easier. Therefore, many manufacturers now use single crystal LEDs as white light LED development direction. 2. Marketing: LED technology has developed rapidly in recent years, brightness has continued to increase, and prices have continued to decrease. In addition to the original LED market, the market has continued to expand in general lighting. Both brightness and price have gradually approached the traditional source. Due to the turbulent situation in the world's oil -producing areas, the problem of global energy shortage has once again become the focus of attention. The development of the LED industry will have a huge impact on the energy and environmental protection policies of a region. The United States, Japan, Europe, and South Korea have all set up national -oriented R & D organizations to accelerate technology development and mass production. At this stage, there is still a long distance from the time to enter the era of white LED lighting. Due to the consideration and cost consideration of white light LED lighting efficiency and cost, about 100LM/W of white light LED in 2010, and 200LM/W in 2020. If the process of white light LED is accelerated, it can slowly appear commercialized products in 2005, and after 2010. In terms of the lighting market, according to FROST & SULLLIVAN's estimates, the global market size of the incandescent light bulb and solar lights in 2000 was about 4.3 billion US dollars, and the annual growth rate was about 5 %. It was about 2.5 times the global visible LED market size in 2000. Therefore, the development space of the lighting market is quite large. Reed Electronics Research Global White -ray LED is estimated to grow to a market size of $ 118 million in 2000. In the next three years, it will maintain a growth rate of about 40 %. In 2003, it reached a market size of $ 270 million. In the future, the cost of white light LED will be further reduced. Except for the existing mobile phone backlight and small -sized LCD backlight, if the market for universal lighting starts, the white light LED market will have greater market potential. White light LED is estimated to have been At first, the market energy will be gradually released, and the demand will gradually increase. At this stage, the application of white light LEDs is mainly used for reading lights, decorative lights, etc. in terms of lighting, and about 95%of the remaining 95%are for small -sized LCD backlighting sources. 1. The market with the screen back light source of the color mobile phone on the white LED market is the largest. Although the maximum use of white LED can be up to 100,000 hours, it must be operated in a low -current environment. At present, this product is mainly used for small -sized backlight sources. From the perspective of various application markets, because color screen mobile phones need to be paired with white light LED as the backlight source, and color screen mobile phones will become the development trend of the mobile phone market in the next few years. According to the industry's market forecast for color screen mobile phones, the proportion of color mobile phones in 2004 is about 40 % In 2005, it is estimated to reach 55%to 60%. About 5-1 billion pieces, in addition, because the white light LED has begun to use the flash of the mobile phone attached digital camera, the proportion of the mobile phone attached digital camera this year is about 15%, and it is expected to increase to 20%next year. 4 estimates, the demand for a year is about 400 million. Secondly, in terms of backlight sources in PDA and digital cameras, according to the estimated valuation of the Economic Capital Center of Zhuhai Industry Research Institute, PDA shipped about 25 million units in 2003, and each use of about 6-8 white light LEDs per unit. It is estimated that about 50 million pieces are required; if the digital camera is used, the number of digital cameras in 2003 in the world is about 30 million units. From this point of view, the demand for white light LED will still be based on the backlighting source market of color screen mobile phones. 2. White -light LED currently uses small -sized LCD backlight as its main cold cathode fluorescent light (CCFL) compared to other backlight technology technology has the advantages of brightness and high luminous efficiency. It is strict, but because the cold cathode fluorescent light of the small tube diameter is more difficult and the cost is not much advantage, the cold cathode fluorescent lamp is mostly used at 4 inches or more (and the size of the mobile phone is more than 1.5 inches to 2.2. In the inch, the digital camera is lightly considered and the size is between here). In terms of large -sized LCD backlight sources, the current cold cathode fluorescent lamp has an absolute advantage in terms of large size and price. Therefore LCD backlight source to use cold cathode fluorescence lamps. Therefore, the dividing point of the white light LED as the LCD backlight and the cold cathode fluorescent light as the LCD backlight is that the small -sized LCD uses white light LED, and the large and medium -sized LCD (such as LCD display, LCD TV) uses cold cathode fluorescent lights. For example, the brightness of the white light LED increases and the cost is further improved. In terms of large -sized LCD, the white light LED replaces the cold cathode fluorescent light as the backlight source. In this way, considering the market potential of large -sized LCDs in PC and TV, the demand for white light LED as a large -sized LCD backlight is very amazing. 3. The biggest of the white light LED market is the general lighting market industry that is most optimistic about the white light LED market is the general lighting market. At this stage, the white LED light emitting efficiency can reach 30LM/W (the ordinary incandescent bubble light emitting efficiency is 15LM/W), but the If the white light LED really occupies a certain market in the general lighting market, the efficiency of the white light LED luminescence needs to be improved to 60-100LM/W. From the perspective of luminous efficiency, once the white light LED exceeds 60lm/W (equivalent to equivalent to the equivalent 20W sunlight), you can start to be popularized in the lighting market. If you can increase efficiency to 80LM/W, it will be popularized to general home various lamps. However, in order to truly occupy the general lighting market, in addition to the fluctuation efficiency and power, the cost is also a very important factor. In terms of luminous efficiency and cost ratio, the cost of white light LED in 2001 is about $ 1/LM. In 2002, to $ 0.1/LM, if the cost can be reduced to $ 0.01/LM, because the white light LED belongs to green and environmentally friendly energy, it is expected that there will be most markets that can completely replace existing general lighting. Third, the patent issues involved in white light LED are currently high -brightness white light LEDs in the world: Nichia, ORSAM, Matsushita, Lumileds, Toyota Gosei, Stanley, Toshiba, Citizen. Do not use patent authorization to release technology. In terms of market competitiveness and positioning, Nichia, Toyota Gosei, Cree, Cree leaders in high -level technologies such as Blu -ray and white light, while European and American large manufacturers Lumileds and OSRAM are the most complete in vertical integration. As LEDs have special and general lighting, LEDs, LEDs, LEDs, LEDs The development of various aspects such as display screens, mobile phone backlight sources, so the layout of market development trend, sales channels and upstream and downstream raw materials and key industrial chains will be the key to improving market share in the market in large international manufacturers. In addition, Baiguang LED involved patent issues. Nichia successfully mass -produced GAN Blu -ray LEDs as early as November 1993, almost monopolized the entire Blu -ray market, but with the improvement of Toyota Gosei and CREE Blu -ray LED, Nichia has been threatened. Since 1996, Nichia has set off. A series of patent litigation disputes, because Nichia adopted a patented technology monopoly market with patent authorization technology, has been in trouble for patent technology. , CREE reached a reconciliation, was forced to start cross -authorization with the above -mentioned company, and could use specific patented technologies for both parties to end the six -year lawsuit. Nichia's patent monopoly basically draws an end. In October 2002, OSRAM authorized the white light LED manufacturing technology to ROHM, and observed that Nichia has not accused OSRAM and Rohm, Nichia's patent ice in recent years,. The lawsuit will spend time conducting infringement investigations, and a large amount of money will fall into the deep pockets of lawyers. Due to the surge in LED market demand, no company can dominate the market. Because the use of LED lighting affects the energy strategy and environmental protection strategy, all countries have a certain reservation attitude towards the Nichia patent lawsuit. This affects the results of the lawsuit that affects the patent of nichia to a certain extent. Select the materials for high -quality LED lamp beads, technology Co., Ltd.

UVLED ultraviolet optical curing technology has developed for so many years. In fact, many people now know that UVLED light sources have the characteristics of low temperature, efficient, and energy saving. this problem. In the UVA band's curing light source (wavelength includes 365nm, 385nm, 395nm, 405nm), it can effectively convert 20%-30%of the input electrical power into ultraviolet light. At the same time (UVC), and far infrared light. The traditional mercury lamp is just the opposite, about 80-90%of the electrical power converted into thermal energy, but the real UVA part we need is a small part. Over. In terms of optoelectronic conversion efficiency, the UVLED light source is compared to the traditional UV mercury light source, and efficient energy benefits are equivalent to saving about 80%-85%of the energy and calorie loss of mercury lamps. The following icons are the comparison of mercury lamps and UVLED lighting spectrums. For you intuitively display the energy distribution of UVLED light sources and ordinary mercury lamps: As can The effective absorption area, this is not difficult to explain the solidification efficiency of UVLED light source and so efficient. At the same time, it can also be seen that the energy distribution of mercury lamps is too scattered, and the invalid part of the solidification directly becomes energy loss. Tianhui launched a series of UVLED solid solutions and energy -saving and emission reduction products in response to the needs of various industries in the market. Welcome colleagues in all industries in the society to consult and communicate.

The convex printing will be raised in the place where the printing version is made, and the place where there is no picture and text will be depressed. When the machine works, the rubber roller with ink on the surface is rolled over the printing surface. A uniform ink layer, while the blank part is not dipped in ink. Under the influence of the pressure agency, the ink is transferred to the surface of the printed object. Most of the convex printing printing currently uses UV processes. UV optical solidification is performed immediately after transfer, which greatly improves printing efficiency. In recent years, with the popularity of UVLED, the UVLED facial light sources are increasing as a cured light source, and the corresponding ink is LED special ink, such as UV161LED. Using UVLED as a curing light source can be accurately controlled, that is, use it, and more energy saving. And UVLED is a cold light source, which is controlled by the temperature rise of the irradiated objects in the light. Many incompetent materials such as PVC are also applied. UVLED face light sources generally use the wavelength of 385nm or 395nm, the same ink, different printing processes, different print thickness, and the wavelengths used are different. If we are thinner, we will choose 385nm, and get better drying in a short time optical curing. When it is thicker, we will choose 395nm, because the wavelength is long and the light penetration is better, so as to obtain a better bonding effect. In addition, in order to increase the liquidity and adhesion of the ink, the two additives are added to the ink raw liquid in the ink raw liquid in a certain proportion in the convex printing. Tianhuilx-S30060 facial light source (385) Tianhui's UVLED face light source uses imported UVLED lamp beads, high-quality constant stream sources, and excellent heat dissipation design. It has the advantages of structural compactness, high reliability, and high stability. Praise.
