摘要
利用对不同波长蓝光芯片激发黄色荧光粉膜条件下制备的空封白光数码管与传统工艺白光数码管进行的测试实验,分析了在相同实验环境下,两种工艺制备的白光数码管光通量与光效存在差异的原因及一些必要的改进措施;通过对显色指数与色温测试值的比较,得出蓝光芯片主波长对上述2个参数的影响。从实验中得到的对光性能的测试数据,可以得出研制基于空封技术的白光数码管的市场可行性。
With the testing experiment of the empty envelope white light digitron prepared under the condition of excitating the yellow fluorescent powder using the different wavelengths of blue light chips and the tradition white light digitron, the different reasons of luminous flux and efficiency of two white light digitrons prepared by two kinds of technologies, and some necessary improvement measure are analyzed under the same testing environment. By comparison of color radix and color temperature testing, the influence of the main wavelengths of blue chip on the mensioned two parameters was obtained, the marketing feasibility of the white light digitron based on the empty envelope technology can be achieved by the tested data acquired in the experiment.
