With the further development of household appliances, controllable switching capacity is provided for household appliances including curtains at present, under the environment, lamps which are important as household appliances and even the most basic components are endowed with intelligentized missions, but at present, the intelligentization of the lamps is realized by adding some functions which do not belong to the illumination range for the lamps, such as 'accidental detection and alarm lamps', the functions of detection and alarm are added for the lamps, and other functions which are separated from the basic functions of the lamps are not provided with practical value. Firstly, the installation range of the lamp is usually beyond the range which can be reached by people at will, the installation of the lamp is not connected through a special power line like large household appliances, the lamp is often directly installed on a lamp holder which is directly connected with household 220V alternating current, the power supply of other non-household application places is possibly higher, unpredictable dangers can be caused by touching control and the like by hands, the maintenance of the lamp is very inconvenient, and if a convenient and controllable lamp is specially added, the lamp is very redundant. Because the nature of lamps and lanterns is the illumination, and at present for domestic lamps and lanterns, the illumination function is really not intelligent, no matter be button switch or touch switch or even remote switch, all need through the switch to control, and under some scenes, it is not so convenient to open or close the switch, for example when only need the illumination of short time late at night. Especially, some users with large rooms and long corridors may have a blind area in front of the switch lamp for a while, and even need to assist the lighting by other lighting devices, which is very inconvenient. For household lamps, the voice-operated switch applied to public places can cause the problem that the lamps are not switched on and off continuously in the daytime without lighting, so that the voice-operated switch is not suitable for the household lamps.
