A radiating lamp casing is made of porcelain, an LED light source is installed at the bottom of an embedded inner metal liner, slots on the periphery of the inner metal liner are in a reed shape, and the inner metal liner is closely attached to the inner wall of the porcelain lamp casing through the reed deformation, so that heat of the LED light source is quickly transferred to the porcelain lamp casing. By the aid of the excellent electrical insulation characteristic of porcelain, the power utilization safety of an LED bulb is guaranteed, at the same time, the inner metal liner which is made of a metal material and is closely attached to the inner wall of the porcelain lamp casing can reduce thermal resistance and improves the overall radiating effect, and the power utilization safety and the high-efficiency radiation of the LED bulb can be achieved. The LED lamp has the advantages that the bulb is safe to use, the radiating effect is satisfying, the structure is compact, the process is simple, the porcelain process is provided with eastern romantic charm, the cost is low, and LED illumination lamps can be popularized.
