【摘要】：根據(jù)《水俁公約》的規(guī)定,2020年為止,禁止一定量以上的水銀電池及熒光燈的生產(chǎn)與進出口貿(mào)易。印刷行業(yè)需要用到大量的紫外固化燈,由于傳統(tǒng)的高壓汞燈不但電耗高,還存在汞污染的危險,必然會退出歷史舞臺。隨著紫外芯片技術(shù)的發(fā)展,紫外LED的能量轉(zhuǎn)換效率越來越高,單顆紫外LED芯片的光效也已滿足要求,紫外LED在高速柔印領(lǐng)域的應(yīng)用條件日趨成熟,因此,紫外LED固化燈必將成為該領(lǐng)域的主流產(chǎn)品。本文主要針對高速柔印機對紫外LED光源的需求,系統(tǒng)設(shè)計制作高能量密度、窄光斑的紫外固化光源,并進行性能測試分析。現(xiàn)在市場上的紫外LED光固化模組主要是利用現(xiàn)有的單顆UV LED或COB直接進行陣列式設(shè)計,難以實現(xiàn)高光功率密度和利用率。本文結(jié)合目標(biāo)固化設(shè)備,從封裝開始進行COB設(shè)計,將LED芯片進行陣列排布,通過光學(xué)設(shè)計和散熱技術(shù)相結(jié)合,并配合后期的二次光學(xué)設(shè)計,獲得了一款高能量密度的紫外LED光源模組,顯著提高了光學(xué)利用效率和被照射區(qū)域的光功率密度,相對市場上現(xiàn)有產(chǎn)品具有更優(yōu)良的性能。本文采用首爾半導(dǎo)體生產(chǎn)的型號為UV1000-38,385nm的正裝垂直紫外芯片,設(shè)計并制作打樣了COB電路板和石英玻璃透鏡,封裝制作1并9串和6并9串的兩種尺寸的COB樣品各一個,利用小尺寸樣品進行了近場測試和熱阻測試。根據(jù)近場測試所獲得的光源參數(shù)數(shù)據(jù),進行6倍陣列以后獲得與大尺寸COB大小相同的光源參數(shù)數(shù)據(jù),通過在光學(xué)設(shè)計軟件LightTools上建模優(yōu)化,得到了一款硅膠透鏡的3D結(jié)構(gòu)模型,并且獲得了10cm距離處的紫外能量密度的模擬數(shù)值。開軟模制作硅膠透鏡,將硅膠透鏡固定安裝在大尺寸COB上,搭建散熱平臺,使用紫外能量計進行量化測試。測試結(jié)果顯示:10cm處的實測值與模擬值十分接近。本課題的研究取得了階段性的成功,為后期完整的印刷光源的搭建奠定了良好的基礎(chǔ),設(shè)計的光源模塊具有市場推廣的實際價值。本課題通過對印刷業(yè)的紫外固化燈需求調(diào)研和現(xiàn)有紫外芯片性能分析,開展了專業(yè)應(yīng)用于高速柔印機的高功率密度的紫外固化燈的設(shè)計研究,并成功設(shè)計出樣品,通過了測試評估,證明了市場和技術(shù)的可行性,對外我國紫外LED發(fā)展具有促進作用。
[Abstract]:In accordance with the Minamata Convention, the production, import and export of mercury batteries and fluorescent lamps shall be prohibited by 2020. A large number of UV curing lamps are needed in the printing industry. Because the traditional high pressure mercury lamps are not only high in electricity consumption but also in danger of mercury pollution, they will inevitably withdraw from the stage of history. With the development of ultraviolet chip technology, the energy conversion efficiency of ultraviolet LED becomes higher and higher, and the light efficiency of single ultraviolet LED chip has met the requirements. The application conditions of ultraviolet LED in high speed flexo printing field are becoming more and more mature. UV LED curing lamp will become the mainstream product in this field. Aiming at the demand of high speed flexo printing machine for ultraviolet LED light source, this paper designs and manufactures high energy density and narrow spot UV curing light source, and carries on the performance test and analysis. At present, the UV LED photocuring module in the market is mainly designed by using single UV LED or COB directly, so it is difficult to realize high optical power density and utilization ratio. In this paper, the COB design is carried out from the packaging of the target curing equipment, and the array arrangement of the LED chip is carried out. Through the combination of optical design and heat dissipation technology, and with the secondary optical design of the later stage, A high energy density ultraviolet (LED) light source module is obtained, which improves the optical utilization efficiency and the optical power density of the irradiated area, and has better performance than the existing products in the market. In this paper, we design and fabricate the COB circuit board and quartz glass lens by using the formal vertical ultraviolet chip of UV1000-38385nm, which is produced by Seoul Semiconductor, and package and fabricate one COB sample of 1 and 9 strings and 6 and 9 strings of COB samples, respectively. The near field test and thermal resistance test were carried out with small size samples. According to the light source parameter data obtained from the near field test, the parameters of the light source of the same size as the large size COB are obtained after 6 times array. By modeling and optimizing on the optical design software LightTools, a 3D structure model of the silica gel lens is obtained. The simulation value of ultraviolet energy density at 10cm distance is obtained. The silica gel lens is made by opening the soft mode. The silica gel lens is fixed on the large size COB, the heat dissipation platform is built, and the ultraviolet energy meter is used to carry on the quantitative test. The test results show that the measured value at 10 cm is very close to the simulated value. The research of this subject has made the stage success, has established the good foundation for the later period complete printing light source construction, the design light source module has the actual value which the market popularizes. Based on the research on the demand of UV curing lamp in printing industry and the performance analysis of existing UV chip, the design of high power density UV curing lamp used in high speed flexo printing machine has been carried out, and the sample has been successfully designed. The feasibility of market and technology has been proved by test and evaluation, and the development of UV LED in China has been promoted.
