An LED bulb structure includes a glass envelope, support, LED light emitting body, tungsten filament light emitting body and electronic element units, where the glass envelope is vacuum-sealed, the support formed by a conducting wire is fixed inside it, both LED and tungsten filament light emitting bodies are configured on the support, the necessary electronic element units are configured on the support between the LED light emitting body and tungsten filament light emitting body, and one side of the support is set to a positive pole and another side thereof a negative pole. As arranged, air will enter the glass envelope of a broken LED bulb to cause the tungsten filament to be burned to break to extinguish, and thus to cause the LED light emitting body to extinguish in such a way to remind users that the broken LED bulb must be replaced with a new one.
