| 摘要 |
一种用于量测一LED3之光特性的光学积分球1，该光学积分球包括在一端部的一入口5，一LED3能为测试被呈现于该处；一遮光器7，其被设置在该入口5处，其中该遮光器7被配置成可在一第一打开位置及一第二关闭位置之间移动，一待被测试的LED3在该第一打开位置能被接收进入该入口5中，该遮光器7在该第二关闭位置能覆盖该LED3被支撑于其上之一套接件9的至少大部分，以致该遮光器能防止由该LED3所发射出的光线被该套接件9的至少大部分从该积分球被转移开。进一步提供有一种包括该光学积分球1的组合。; a shutter 7 located at the inlet, wherein the shutter 7 is configured to be moveable between a first open position in which an LED 3 to be tested can be received into the inlet 5, and a second closed position in which the shutter 7 can overlay at least the majority of a nest 9 on which said LED 3 is supported, so that the shutter can prevent light emitted by the LED 3 from being diverted away from the integrating sphere by at least the majority of the nest 9. There is further provided an assembly which includes the light integrating sphere 1. |
