The two wireless control technologies have length and length respectively. However, in many places, only WIFI signals or bluetooth signals or areas where bluetooth signals are insufficient and bluetooth is difficult to reach can only use WIFI signals, which limit the use of the LED intelligent lamp, so that the connection and control of the LED intelligent lamp are very inconvenient.
