1。PC扩散板在照明设备中便宜,方便且便携。但是,由于外部自然光的干扰,测量值通常更高。该仪器仅适用于参考比较,不能用作准确的仪器。
2。传输雾剂测试仪:PC磨砂扩散板受外部因素的影响较小,因此测试结果比照明仪更低,更准确。一般而言,扩散器制造商使用此仪器来测试其产品的传输雾化。
3。集成球:集成球非常准确地测量扩散板的透射率,并且几乎不受外部环境干扰的影响,因此从测试同一板中获得的数据低于上述两个。由于工具的高成本,只有大型照明公司使用此设备来衡量透射率。 (注意:诸如尺寸,位置位置,距探针的距离以及探针和集成球的光源之间的距离等因素都会影响测试结果)。
4。光强度分布:光强度分布是灯是否具有商业价值的指示工具,因为它是使用其所有一对一灯的唯一光学完整性测试。上面的其他一些工具仅是测量光分子或物质的定义。是否只能通过它来衡量该灯中满足国际照明协会的要求。
