The device circuit works shown in Figure 11. Power outages are frequent thing, but some occasions, the power does not allow (such as the ongoing surgery, etc.). LSE with simple circuit design, fully automated.

When 220V AC, the lamp H1 lights up, while the LSE feet high output, transistor VT end, the relay J is released, it does not shine direct light H2. Once a power outage, H1 off, LSE's pin output low, then transistor VT conduction, the relay J pull, turn the power lights H2, H2 light automatically convert between almost two lights interruption.
