Most of the existing LED lamps have no timing function, so that the LED lamps are inconvenient to use, such as when a user goes out and forgets to turn off the lamps, the LED lamps can only work until the user comes back and then turns off due to no timing function, or for example, when the user falls asleep suddenly at night, the LED lamps can work until the user wakes up due to no timing function, and therefore electric energy and the service lives of the LED lamps are wasted. Although some LED lamps have a timing function, the timing is realized by using a mechanical timer, and the timing setting needs to be performed again every time the LED lamps are used, which is not easy to use.
