【摘要】：通过选择合适的多种荧光粉,尤其是发射峰值波长较低的绿色荧光粉,制备了无视觉系统危害LED白光及半导体制造黄光室专用的黄光光源,即发射蓝光强度较低,无光生物危害的LED封装光源。实验中,详细研究了有机硅封装胶A、B组分不同混合比例、不同点胶量、不同荧光粉比例及抗沉淀剂用量对2835封装光源色温、显色指数和光效的影响。实验结果表明,通过采用最佳封装原材料配比及最优封装工艺参数,可制备相关测试结果远低于国际相关标准的无视觉系统危害LED光源。最后,还成功将制备的无视觉系统危害LED光源应用到台灯和黄光灯的生产中,取得了很好的效果。
[Abstract]:By selecting suitable kinds of phosphors, especially the green phosphors with low emission peak wavelength, the yellow light source which has no harm to LED white light and semiconductors to make yellow light chamber is prepared. That is, the LED packaging light source with low blue light intensity and no light biological harm. In the experiment, the different mixing ratio and different dispensing amount of organosilicon packaging adhesive are studied in detail. The effects of different phosphor ratio and the amount of anti-precipitating agent on the color temperature, color index and light efficiency of 2835 packaging light source were studied. The experimental results showed that the best packaging raw material ratio and the optimal packaging process parameters were adopted. The results can be compared with the international standards. Finally, the non-visual system harm LED light source is successfully used in the production of desk lamp and yellow lamp. Good results have been achieved.
