Abstract
A method for controlling a remote LED lamp includes: using a memory unit (452) to record a standard value for indicating a normal environmental brightness and a reference value for indicating a normal LED brightness; using a first sensor (41) to detect real-time brightness of the environmental light and transmit a signal (31) indicating the real-time brightness to the memory unit; using the memory unit to compare the signal with the standard value to obtain a result; using a driving unit (451) to control the LED light lamp to be turned on/off according to the result.
