1. A bulb structure of an electrodeless lighting system, comprising:
a bulb body having an interior space which receives a luminous material which emits light when microwave energy is applied thereto;
a bulb support portion integrally extending from one side of the bulb body which supports the bulb body, connects to a bulb rotating motor, and includes therein a passage through which the luminous material is injected;
a covering portion provided at an end of a communicating portion where the bulb body communicates with the bulb support portion, so as to hermetically seal the bulb body, the covering portion comprising a covering member configured for insertion through the passage of the bulb support portion; and
a reflector formed independently of the bulb body, the reflector installed about the bulb body and configured to reflect the light emitted from the bulb body.
