日本专利:MATSHITA 电子公司研制。在荧光灯玻壳内壁上涂敷的荧光材料构成如下:(a)由二价铕激活的铝酸锶,化学式为:4(Sr_(1-x)Eu_x)O·yAl_2O_3,式中 x=0.005—0.2,y=6—8。 (b)由 Sn 激活的 Sr,Mg 的正磷酸盐和/或由 Sn 激活的 Sr,Ba,Mg,的正磷酸盐。(c)由激 Sb,Mn 活的碱土卤磷酸盐和/或由 Sb 激活的碱土卤磷酸盐。与常规的 EDL 型荧光灯相比较,这种灯的效率得到了明显的改善。这种灯具有满意的显色性且在整个寿命期间内保持稳定。在制备过程中易于实现颜色匹配。
Japanese patent: MATSHITA Electronics company development. The fluorescent material coated on the inner wall of the fluorescent bulb is composed as follows: (a) strontium aluminate activated by bivalent europium, the chemical formula is: 4 (Sr_ (1-x) Eu_x) O.yAl_2O_3 wherein x = 0.2, y = 6-8. (b) Sr, Mg orthophosphate activated by Sn and / or orthophosphate of Sr, Ba, Mg, activated by Sn. (c) alkaline earth halophosphates activated by activated Sb, Mn and / or alkaline earth halophosphates activated by Sb. Compared with the conventional EDL-type fluorescent lamps, the lamp efficiency has been significantly improved. This lamp has a satisfactory color rendering and remains stable over its lifetime. In the preparation process easy to achieve color matching.
