提出了一种新的白光数码管封装技术,围绕新封装技术中荧光粉厚度是否能保持相对均匀、稳定。对新封装技术制备样品的性能进行测试,并与传统以环氧树脂为配粉胶的白光数码管进行了比较。分析实验数据表明,采用点胶技术研制的白光数码管,各笔段荧光粉层厚度保持着相对的均匀和稳定,笔段间的发光强度误差较小;在相同的测试环境下,光通量的衰减程度比传统白光数码管要慢,由于硅胶良好的导热性,点胶技术白光数码管对环境的适应性更强。研究表明点胶技术白光数码管作为一种新的封装技术比旧方案更优越。
A new white light digital tube packaging technology is proposed. Whether the thickness of the phosphor in the new packaging technology can be kept relatively uniform or not is stable. The performance of the samples prepared by the new packaging technology was tested and compared with the conventional white LED with epoxy resin. Analysis of experimental data shows that the use of white glue technology developed white digital tube, each paragraph of the phosphor layer thickness remained relatively uniform and stable, the pen between the light-emitting intensity error is small; in the same test environment, the luminous flux attenuation Degree of slower than the traditional white digital tube, due to the good thermal conductivity of silicone, white plastic dispensing technology more adaptability to the environment. Research shows that dispensing technology white LED as a new packaging technology superior to the old program.
