LED光学玻璃透镜模组光源投光灯高杆灯隧道灯船用灯
LED玻璃透镜投光灯的优势: 玻璃透镜连板设计,突破了传统的模组采用的PC连板透镜,带来一种全新的体验,有效地克服了PC透镜的不良问题:1、抗腐蚀能力:高硼硅3.4玻璃属于硼硅酸盐玻璃中的硼硅玻璃,耐酸耐碱,抗腐蚀性能优越。2、耐温性强:相比PC透镜,其热膨胀系数较低,拥有良好的热稳定性,光学表面温度的变化小,保留原有的光学照明效果。3、透光率高:常规PC透镜透光率在85%左右,造成光照的浪费,玻璃透镜透光率为90-92%,镀加增透膜后可高达97%。4、相比于PC透镜,玻璃透镜不会产生老化/黄化现象,从而影响透镜透光率。5、相比于PC透镜,玻璃透镜不会吸附灰尘,并且方便清洗。隧道照明配光发光角度120°×80°、150°×80°(对称)等多种配光角度,合理的照度均匀度和防眩光等级等设计有效的改善隧道内路面的墙壁照明状况,改善隧道内视觉享受,减轻驾驶员驾驶疲劳。道路配光有TYPE2-M、TYPE3-M等多种配光角度,其配光在路面形成照度均匀的类矩形光斑,可以适用于双向八车道、六车道、四车道、二车道、一车道道路情况。高杆灯配光应用于大型广场、主干道交叉路口、码头、车站和体育场等场所中,悬挂高度较高,照明范围比较广泛而且均匀,能够带来较好的照明效果,满足大面积场所的照明需求。工矿灯配光发光角度45°/60°/90°/120°(25°开发中),主要应用于大楼外墙、桥梁、公园、广告招牌、球场广场、工厂车间照明。
LED光学透镜用透明稀土陶瓷材料的好处
稀土透明陶瓷是一种特殊的陶瓷材料,其中稀土元素以化合物形式或掺杂形式存在。通过调整其光学、电学、磁学等性能,实现特定功能的陶瓷材料。稀土元素具有独特的电子结构和光学性质,因此在陶瓷中掺杂稀土元素可以显著改变陶瓷的光学性能,如发光、吸收、透射等。 稀土透明陶瓷的性能调控是关键,通过调整稀土元素的种类、掺杂浓度、制备工艺等参数,可以实现对陶瓷光学性能的精确控制。例如,通过调整稀土离子的种类和浓度,可以改变陶瓷的发光颜色、发光强度等光学性能;通过优化制备工艺,可以减小陶瓷的晶粒尺寸,提高陶瓷的透明性等。稀土透明陶瓷主要包括氧化物和非氧化物两大类。氧化物透明陶瓷主要包括YAG、Y2O3、MgAl2O4、TiO2、ZrO2等。其中,YAG(钇铝石榴石)是一种常用的氧化物透明陶瓷材料,具有高折射率、高透光性、高硬度和高热稳定性等特点,因此在激光、光学、陶瓷切削等领域得到广泛应用。非氧化物透明陶瓷则主要包括A1N、CaF2、ZnS、Si3N4等。其中,氟化物透明陶瓷如CaF2具有较高的密度和较高的分凝系数,因此在光学透镜应用方面具有优势。此外,由于氟化物的晶体结构复杂,可以灵活地掺杂不同的稀土元素,以调整其光学和其他物理性质。 稀土透明陶瓷因其独特的物理和化学性质,在众多领域有着广泛的应用。 首先,稀土透明陶瓷在激光技术中有着重要的应用。由于其具有高透光性和良好的热稳定性,稀土透明陶瓷可作为激光器的窗口材料,用于承受高功率激光的辐射,并保持激光的稳定输出。此外,稀土元素在陶瓷中的掺杂可以调整陶瓷的光学性质,从而实现特定波长的激光输出。 其次,稀土透明陶瓷在光学传感器中也有广泛的应用。由于其具有高折射率和高透光性,稀土透明陶瓷可用于制作光学透镜、棱镜、反射镜等光学元件,用于光学传感器的构建。此外,稀土元素在陶瓷中的掺杂还可以提高陶瓷的光敏性,从而实现光学传感器的灵敏度和精度的提高。 此外,稀土透明陶瓷还在高温窗口、红外探测器、陶瓷切削等领域有广泛的应用。例如,氧化物透明陶瓷如YAG、Y2O3等具有良好的高温稳定性和化学稳定性,可用作高温窗口材料,用于承受高温环境下的观察和测量。非氧化物透明陶瓷如A1N、CaF2等则具有优异的光学性能和机械性能,可用于红外探测器的制作。稀土透明陶瓷是一种具有优异性能和应用前景的新型陶瓷材料,其在光学、激光、航空航天等领域的应用潜力巨大。随着科技的进步和研究的深入,稀土透明陶瓷的应用前景将更加广阔。为了制备出高质量的稀土掺杂透明陶瓷,需要深入研究的难点有很多,并采取相应的解决措施。稀土掺杂透明陶瓷的工艺难点主要有以下几个方面: 1. 粉体制备过程中的团聚问题:在制备稀土掺杂透明陶瓷的粉体料浆过程中,纳米级前驱体颗粒在干燥时容易发生团聚,这会导致后续煅烧过程中陶瓷颗粒的长大和团聚,影响陶瓷的透明性。 2. YAG纳米粉体的长大机制不明确:煅烧过程中,前驱体经历热分解,形成YAG晶核并逐渐长大。晶粒长大的机制涉及到原子或离子的扩散、表面能和界面能的变化等因素。在纳米尺度下,晶粒的长大速度受到表面能和界面能的影响更为显著,因此,纳米粉体在煅烧过程中容易发生团聚和长大。此外,制备工艺中的温度、气氛、时间等因素也会对YAG纳米粉体的长大机制产生影响。过高的温度可能导致晶粒过度长大,降低陶瓷的透明性;而温度过低则可能导致前驱体分解不完全,影响YAG粉体的纯度和性能。 3. 烧结过程中的晶粒长大和气孔排除:在粉体成型和烧结过程中,工艺参数如成型压力、烧结温度等对陶瓷微观结构的影响规律需要进一步研究。由于纳米粉体的原子扩散活化能较大,烧结过程中晶粒生长过快可能会产生晶界裂缝,许多气孔被晶粒包围,使得气孔难以排除,影响陶瓷的透明性和力学性能。 4. 多组分体系的沉淀反应过程复杂:对于稀土元素掺杂的多组分体系,其沉淀反应过程复杂,前驱体的结构和组成受到溶度积和沉淀速率等因素的影响,需要进一步研究沉淀过程对前驱体组成和结构的影响,以及其对随后煅烧过程的影响规律。 5. 氟化物透明陶瓷的易水解/热解性:对于氟化物透明陶瓷,其制备过程中的一个难点是氟化物易于热解,即在高温下与水或水蒸气反应形成相应的氧化物和含氧氟化物。这些产物与初始氟化物不是同晶相的,会在陶瓷中形成第二相,破坏材料的光学均匀性。因此,在透明陶瓷制备过程中需要采取必要的预防措施来防止水解(热解)。
