积分球球内温度对光通量测量值的影响

The Effect of Flux Test with Different Temperature in Integrating Sphere

在日常使用积分球对测试样品进行光通量测量的时候会发现即使是同一套测试设备和同一个测试样品在相隔几个月后重新进行光通量测量有一定概率会得到有一定差异的结果。而造成这个差异的原因则有可能是试验时积分球内温度不同而导致的。我们通过多款不同类型的灯具分别在多个不同积分球球内温度下进行试验,并对试验结果展开分析,最终发现:不同温度下光通量测量不同,是由于灯具在不同温度下发出光通量不同所导致的。

It’s possible to get an inconsistent flux when we test the same lamp with the same integrating sphere system.The reason of the variance is probably the temperature in integrating sphere was different when we test.We had found the reason of different flux test in integrating sphere with variance temperature that is the lamps will luminous different in different temperature by making experiments with different types of lamps in different temperature in integrating sphere.
