| 摘要 |
An LED light has a built-in, added-on, or snapped-on sound device such as a whistle to allow people to generate a loud sound that can be heard by other people during conditions such as an earthquake, flood, typhoon, hurricane, tornado, fire, bombing, tsunami, terrorist attack, and so forth. The LED light normally serves as non-portable light device which can be installed in a certain location, but which can be removed in the event of an emergency to serve as a power fail or emergency light. The LED light, without the sound device, may also be applied to an electrical outlet wall plate cover. |
