设备:已校准过的HPCS320光谱仪
样品:XHP50.3 2700K、XHP50.3 3000K、XHP50.3 3500K、XHP50.3 4000K、XHP50.3 4500K、XHP50.3 5000K、XHP50.3 5700K带基板灯珠
说明:测试的时候,有出现色温和显指波动现象,为了让测试更准确,不断调整电压和角度让色温保证和灯珠色温数值一致!
经过光谱仪测试,得出:
XHP50.3 2700K Ra(CRI):94.42138539
XHP50.3 3000K Ra(CRI):93.04648181
XHP50.3 3500K Ra(CRI):94.06105022
XHP50.3 4000K Ra(CRI):94.05354331
XHP50.3 4500K Ra(CRI):95.23299759
XHP50.3 5000K Ra(CRI):93.50396326
XHP50.3 5700K Ra(CRI):93.48740641
XHP50.3 2700K R9:65.95480854
XHP50.3 3000K R9:60.20670907
XHP50.3 3500K R9:67.90142439
XHP50.3 4000K R9:77.99477722
XHP50.3 4500K R9:84.38340336
XHP50.3 5000K R9:75.96253989
XHP50.3 5700K R9:72.92921905
然后通过py程序色温对应光谱数据进行推算,得出3D光谱图,还对光谱进行显色计算。
从3D光谱曲线图上看,可以看出色温越低,红橙谱线越高,青蓝谱线越低,显色表现更好,光效低,照明的颜色偏黄(偶尔带粉),反之色温越高,蓝光谱线越高,照明的颜色偏蓝,显色指数偏低,但光效越高,正是这颗LED特性,所以显色指数和光效两者不可兼得。
接下来看显色指数的曲线图,可以看出2700K显色指数表现较好,3500K左右明显反弹,显色指数的峰值在4500K左右,直到5000K出现断裂现象(这个问题我不知道什么回事),然后慢慢下滑。
由此结论有可能是灯珠品质决定的,应该是用不同的荧光粉导致的,于是比较理想的色温范围应该是3000K至5000K,要说高显指和光色正的话,4500K是合适不过了。
如果需要更高精度的话,配积分球测试更好!
