The invention discloses an intelligent LED (Light Emitting Diode) lamp control system, comprising an intelligent bracelet and a lamp system in communication connection with the intelligent bracelet, wherein the intelligent bracelet is worn on the arm of a person, and comprises a heartbeat detection module, an action detection module and a first communication module; and the lamp system comprises a brightness acquisition module, a brightness contrast module, a second communication module, a data processing module, a control module, a switching module and a brightness adjusting module. The heartbeat and acceleration information of the person is detected by the intelligent bracelet, whether the person is in a sleep state can be judged according to the detected heartbeat information, and a switch of a lamp is thus controlled; and a brightness detection module is mounted indoors, and when the brightness of light is insufficient, the brightness adjusting module adjusts the brightness of the lamp, so that power is saved and eyes are protected.
