背景技术
线性光源由于具有聚光效果好、亮度高等优点而被广泛应用于各类的视觉检测项目中，然而传统的线性光源普遍存在着光源亮度一致性差的问题。
如附图1中所示，相关技术中线性光源的灯珠1’通常采用均匀阵列的排布，中间出光区域A处的光线重叠覆盖较为密集，而两侧的出光区域B和C处的光线重叠覆盖较少，因此，导致传统的线性光源普遍存在着中心位置比两端的亮度更高的问题；另外，线性光源中每个灯珠1’存在着电压差异等因素，容易导致每颗灯珠1’的光斑亮度不一致，光源整体的出光不均匀，亮度一致性差。
为解决上述出光亮度不一致的问题，行业内通常将灯珠1’与控制器进行连接，通过手动设置控制器的每个通道输出功率，再测试每个位置灯珠1’的亮度，每个位置均需要逐个进行测试，效率低下，而且精度较差，无法满足实际的使用需求。
