主要应用是将摄像机作为线传感器运行（LinesensorMode）。然而，由于该应用的功耗非常高，因此必须考虑到总功耗。
闪烁 LED 的电源由反复充电的电容器提供。在最大10 毫秒和 1:9 的暂停时间下，电容器最多需要 90 毫秒的充电时间（恒定电流下从 0 到 100% 的线性充电），电流才会闪烁。这意味着在一定时间后，电容总是以相同的百分比充电。
The main application is operation of a camera as a line sensor (LinesensorMode). Since this application is very intensive in terms of power consumption, however, the total power must be taken into account.
The power for flashing the LED is provided by capacitors that are charged again and again. At max. 10 ms and 1:9 pause time, there is a maximum of 90 ms to charge the capacitor (from 0 to 100% linear charging with constant current) for the current to flash. This means that after a certain time, the capacity is always recharged by the same certain percentage.
