The present invention relates to a light emitting diode (LED) lamp. It includes several LED elements, human body inductor (ultrasonic sensor, electrofocusing infrared sensor, LED reflected infrared sensor and others), light-sensitive element (photoresistor, photodiode and phototransistor, etc.), lamp panel, time regulating switch, control circuit and LED lamp base with bulb and copper lampholder in which it utilizes human body inductor to produce detection effect for human body, generally the LED lamp is in state of low intensity of light, when human body is close to it, then low intensity oflight can be changed into high intensity of light, and when the intensity of the light is insufficient, the lamp source can be completely opened or semi-opened, and when the intensity of light is sufficient, the lamp source can be switched off.
