Abstract: The invention discloses a light emitting device capable of being controlled by a remotely located mobile phone, and a method and a system for controlling the light emitting device. The light emitting device comprises a light strip and a control panel, wherein the light strip includes a printed circuit board, lamp beads, and a butt terminal, and wherein the control panel comprises a remote connection module and a control module. The method for controlling the light emitting device may include detecting vibrations in the environment, determining whether to transmit signals based on the detected vibrations, determining whether to trigger changes in the lamp bead operation, based on signals received from a the remote communication device and/or from the sensor module.
