Fluorescent lamp
专利汇可以提供Fluorescent lamp专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a fluorescent lamp, which has a color rendering index, which is in the range of that of the SDL type and higher than that of the conventional one by not less than 30%, by providing a phosphor film prepared by mixing the calcium halophosphate phosphor activated with antimony and manganese with the red-emitting yttrium oxysulfide phosphor activated with europium. CONSTITUTION:110l of butyl acetate solution of nitrified cotton is mixed with the following matters for 2hr by means of a bowl mill: 36.7kg of the calcium halophosphate phosphor activated with antimony and manganese, the emissional peak of antimony of which corresponds to 14.5% of the emissional peak of manganese contained in it; 21.0kg of the strontium borophosphate phosphor activated with divalent europium; 5.3kg of the cerium magnesium aluminate phosphor activated with terbium; and 37.0kg of the yttrium oxisulfide phosphor activated with trivalent europium. A fluorescent lamp of 40W is made by use of thus prepared suspension by the usual method. The spectral energy distribution of thus made fluorescent lamp is indicated as the curve 7 in the figure.，下面是Fluorescent lamp专利的具体信息内容。
