Description

一种彩色发光模块及光源 技术领域
本发明属于光电子显示和照明技术领域， 涉及一种使用多种荧光 材料制成的彩色高分子发光模块及光源。 背景技术
LED作为一种新型的节能光源， 因其亮度高， 节约能源， 寿命长等 优点， 被广泛地应用在各种照明场合。
目前的 LED照明装置通常是采用封装荧光发光材料方式得到的， 此类专利也已经有很多， 如中国专利 CN1941431《白色发光元件及其 制造方法》 ， 中国专利 CN1510766《表面安装型白色发光二极管》 ， 中国专利 CN101186818《蓝紫光或蓝光激发的荧光体及制造方法与封 装的白光二极管》 ， 均为荧光材料混合在树脂中涂抹在 LED芯片上制 成白色发光器件。 但是除了白光 LED，市场需要更多其它颜色的 LED 光， 采用以上专利方法也可以制成彩色光， 但是由于该方法制备出的 发光器件很难保证亮度、 色坐标、 色温和显色性的一致性， 并且由于 荧光粉贴近芯片， 受到热量的影响很容易老化以至于引起颜色的改变， 寿命降低。
专利 CN1425868《一种多彩装饰灯》，专利 CN1450301《彩虹灯》， 专利 CN201866692U《一种 LED全彩灯》都介绍了彩色灯的研制， 但 是这几项专利都是通过电路方式， 使不同颜色芯片单独或同时发光来 改变灯光的颜色。 这样造成了电路的复杂性和大批量使用芯片的浪费。 发明内容

发明详述
本发明所述的彩色发光模块中， 所述的荧光材料被 LED芯片发出 的光激发发光， 并且与未被荧光材料吸收的光复合成白光或其他颜色的 光。 所述的各种荧光材料其体色及发光颜色具有不同的特征， 在制造彩 色发光模块时可依据各自不同的情况加以选用。 选择硅酸盐、 铝酸盐发 光荧光材料作为橙色、 黄色发光荧光材料， 选择硅氮化物、 硫氧化物发 光荧光材料作为红色发光荧光材料， 可将黄色发光荧光材料、 橙色发光 荧光材料和红色发光荧光材料复合使用， 复合使用可调整色坐标、 色温 和显色指数， 达到适用于多种用途的目的， 采用发出黄色光的荧光材料 与发出红色光的荧光材料复合使用， 提高显色指数， 得到高显色指数的 白光， 使其适用于需要高显色指数的发光器件中。 所述彩色发光模块与 LED芯片复合，合成白色的光源或其它色彩的光源，用于灯具、数码管、 背光源的光源器件中。 本发明的彩色发光模块同时包含至少两种不同的 颜色区域， 每个区域内的荧光粉在被峰值波长在 380 ~ 475nm 的 LED 芯片激发后发射出峰值波长在 430 ~ 650nm的光， 荧光材料所发的光与 激发光源所发的光复合成白色或其它颜色的光； 整个模块便可以同时发 出不同颜色的光。
本发明中所述的荧光材料可以采用大连路明发光科技股份有限公 司的 LED荧光粉。 例如， 黄色荧光粉可采用硅酸盐荧光材料、 铝酸盐 荧光材料或复合氧化物， 型号分别为 LMS-4453-B , LMA-4453-B , LMY-4453HB; 红色荧光粉可采用硅氮化物、 氮化物荧光材料或硫氧化 物， 型号 LAMS-R-6633, LAM-R-6633, LMS-R-6633; 绿色荧光粉可 采用硅酸盐和铝酸盐荧光材料， 型号为 LMS-2564和 LMA-2564; 蓝绿 色荧光粉可采用硅酸盐荧光材料和铝酸盐荧光材料， 型号为 LMS-1858 和 LMA-1858; 橙色荧光粉可采用硅酸盐荧光材料， 型号为 LMS-5841。 本发明所述的高分子材料可采用有机硅橡胶， 例如， 可以采用透明 性好、 柔软、 弹性好的双组份加成型加温硫化液体硅橡胶， 如双组分有 机硅橡胶材料 Dow Corning 6550、信越 KE1310ST。 这种树脂具有热氧 化稳定性好、 优异的电绝缘性能、 卓越的耐潮、 防水、 防锈、 耐寒、 耐 臭氧和耐候性能。 该树脂在长时间高温状态下工作也不会黄变， 并且固 化后仍然具有柔软有弹性的特点， 并具有一定的强度， 可以随意弯曲变 形， 适用于不规则形状的器件使用。 但加成型有机硅橡胶表面极性低， 不易和其它物质粘接， 即使与硅胶自身粘接， 强度也很小， 容易剥离。 因此， 本发明通过向体系内添加交联抑制剂和偶联剂， 降低有机硅橡胶 的交联副反应， 改善其表面活性， 使相邻区域间反应形成无缝结构。 交 联抑制剂使在制备单个区域的发光模块时， 能充分抑制有机硅橡胶的交 联副反应的发生； 通过添加偶联剂对有机硅橡胶进行改性， 引入易反应 的官能团， 使发光模块的区域间在硅橡胶热固化时进行反应， 同时通过 控制反应工艺条件控制有机硅橡胶表面官能团的反应程度， 最后使整个 模块进行完全固化， 从而使相邻区域形成无缝结构连接， 浑然一体。
本发明采用的是有机硅橡胶、 稀释剂、 荧光材料、 助剂和交联抑制 剂混合均匀后注入模具内， 经加热聚合而固化成型， 变成与模具内腔形 状相同的制品。 采用浇铸的方法摆脱了传统的封装方法制备 LED的形 式， 只需要将彩色发光模块与 LED芯片组合使用即可形成 LED光源， 发光效果与封装形式制备出的 LED光源十分接近。 大大减化工艺步骤， 其生产效率高、 易实现生产自动化、 改善操作环境， 更重要的是荧光材 料在高分子树脂中分散均匀， 用它制成的发光器件的一致性大大改良、 光转换效果好。
同时， 还可以根据实际使用情况浇铸出合适的形状和需要的颜色。 可以有效实现二次配光设计、 提高出光效率、 优化光学分布。 采用这种 方式制备的发光器件安装、 维修、 更换十分方便， 简化了施工工艺， 生 产出的产品更加灵活多样。 本发明的另外一个优点是， 由于荧光材料是 一种无机材料， 这种材料在与金属材料摩擦的过程中极易变黑、 失去发 光性能， 当采用如注塑等方式进行成型时， 荧光材料由于摩擦、 挤压会 出现变黑， 发光性能下降的问题， 而采用浇铸方式则可以有效的避免这 种现象。 但常规的浇铸方法对于制备彩色发光模块仍具有一定的局限 性， 常规浇铸方法制备的彩色发光模块其区域间连接强度不够， 因为加 成型有机硅橡胶表面极性低， 不易和其它物质粘接， 即使与硅胶自身粘 接， 强度也很小， 容易剥离。 因此迫切需要对其进行改进， 为此本申请 创新性的发明了分步浇铸法， 同时通过同时向体系内添加偶联剂和交联 抑制剂的方式成功地实现了彩色发光模块的制备， 使彩色发光模块的区 域间的连接强度高， 同时无缝连接。
综上所述， 本发明提供的彩色模块荧光材料分布均匀， 几种颜色之 间无缝连接， 发光颜色转变自然， 发光一致性好， 由于荧光材料不紧贴 芯片， 避免了由于热量导致的颜色消退问题， 可有效提高产品的寿命。 附图说明
