The invention discloses an intelligent LED energy-saving lamp. The intelligent LED energy-saving lamp comprises a base, a cylinder, a base plate, a lampshade covering the upper portion of the base plate, and an intelligent control device arranged in the base. The upper portion of the cylinder is closed, and the base plate is vertically fixed to the upper portion of the cylinder and is in a cylinder shape. A plurality of light emitting diodes are embedded in the upper portion of the base plate. The intelligent control device is arranged in the base and comprises a master controller, a temperature control switch, a temperature difference power generating sheet, a lithium battery, a temperature sensor, a photosensitive sensor, a camera, an infrared receiver, a 4G network module, a loudspeakerand a sound sensitive sensor, wherein the temperature control switch, the lithium battery, the photosensitive sensor, the sound sensitive sensor, the camera, the infrared receiver, the 4G network module and the loudspeaker are electrically connected with the master controller. The temperature difference power generating sheet is electrically connected with the lithium battery, and the temperaturesensor is electrically connected with the temperature control switch. The disclosed intelligent LED energy-saving lamp is high in intelligent degree and capable of automatically conducting high-temperature protection, the sound, light and remote controller switch is arranged, the temperature difference power generating sheet can convert heat released during work of the LED energy-saving lamp intoelectric energy, accordingly energy is saved, the effect of photochromism is achieved as well, and the intelligent LED energy-saving lamp is suitable for being used in stages, and capable of enhancing the stage effect.
