昨天收到客户的询盘，标题是应急灯。今天又问很急的样子。我看了半天都不懂 If we have a roomwith fall ceiling and 8 ceiling spots connected to the power supply of
the house. In-case we have a power cut so i need 2 of these ceiling
spots to light the room . so we need an emergency circuit (inventor ,
battery and switch between Battery and AC) to be connected to the 2
needed spots so when their is a blackout they switch it on the battery
circuit until the electricity returns. 请问这是什么意思啊？ 请大家帮帮忙解释下。多谢了

如果我们房间吊顶上有8盏灯跟房子的电路相连。
In-case we have a power cut so i need 2 of these ceiling spots to light the room .
为了在断电的时候，我们仍然有2盏等可以作为应急照明。

所以我们需要为这两盏灯连一个应急电路（电池，开关等）。在断电的时候我们可以打开应急电路来照明知道恢复供电。
