在至少另一个实施例中，还提供了一种点灯机，包括如上所述的背光源监测装置以及固定在所述背光源监测装置上的背光源。

由于本实施例中在背光源放置区域上方均匀放置多个光强监测笔，因此可以获得多个区域的背光源亮度，根据多个亮度值可以计算出背光源的平均亮度值，该平均亮度值能够准确地体现背光源的亮度。

在至少另一些实施例中，如图7-8所示，背光源监测装置包括基台3，设置在基台3上的固定结构，固定结构能够将背光源1固定在基台3的背光源放置区域上，背光源1上覆盖有基板2，基板2为透明基板，能够对背光源1进行保护。背光源监测装置还包括设置在基台3上的亮度调节元件，亮度调节元件能够为背光源1提供大小可调节的驱动电流，以对背光源1的亮度进行调节，这样不需要将覆盖背光源1的基板2从背光源1上拆除，就能进行背光源1亮度的调节。具体地，亮度调节元件可以设计为旋钮，通过旋转旋钮就可以改变输入到背光源中驱动电流的大小，进而调整背光源的亮度。进一步地，亮度调节元件还可以设计为上下可调按钮，通过上下可调按钮可以改变输入到背光源中驱动电流的大小，进而调整背光源的亮度。

图9为本实施例背光源监测装置的电路示意图，如图9所示，背光源电阻为R，滑动变阻器电阻为R’，电源电压为U，则通过背光源的电流强度I为：
I＝U/(R+R’)                  单位为：毫安。
图10为点灯机背光源亮度值与通过背光源的电流大小的拟合线图，可以看出，通过背光源的电流与背光源的亮度值存在换算关系，因此，可以通过以下公式计算出背光源的亮度：
B＝-6.209*I2+671.3*I-17738            单位为：cd/m2。
可以将该电流与亮度值之间的换算公式通过程序写入集成芯片9中，这样在电流表10测量出通过背光源的电流强度I之后，集成芯片9就可以计算出背光源的亮度值，显示屏8即可显示出背光源的亮度值。
在利用本实施例的背光源监测装置对背光源亮度进行监测时，可以通过亮度调节元件调整输入到背光源中的驱动电流的大小，再通过光强监测笔对背光源的亮度进行监测，显示屏显示背光源的亮度值，从而实现背光源亮度值的数字化和可监控化，实时、精确地监测背光源的亮度。
通过集成芯片(内有程序控制)时，光强度换算公式通过程序写入该集成芯片。
在进行点灯检测时，如果背光源受到外在因素影响亮度发生变化，可以通过背光源监测装置对背光源的亮度进行调节和监测，使得背光源的亮度保持在一定的数值，保持点灯检测时画面的准确性和一致性。通过本实施例的技术方案能够避免人为因素造成的误差，准确监测背光源的亮度，降低了点灯机背光源亮度调整时的宕机时间，减少了设备调试时点灯机本身的错位风险。
