The invention relates to a method for preparing a microwave sulfur lamp bulb, which solves the problems that the existing preparation process can not ensure high vacuum degree in the bulb and the purity of the pumped powdered sulfur and the charge amount of Ar gas and sulfur can not be easily controlled so as to result in that the luminous brightness, efficiency, color rendering and service life of the prepared sulfur lamp are all reduced. The invention has the preparation method that: 1. a device is prepared; 2. the device is heated and vacuumized so as to ensure that the vacuum degree in the device is maintained between 0.0002Pa to 0.0008Pa; 3. the glass tip which is convex from the upper part of a glass vessel is cracked; 4. the temperature of the powdered sulfur in the glass vessel is enhanced by adopting the Muffle furnace so as to ensure that the powdered sulfur in the glass vessel is evaporated into a quartz bulb; 5. the quartz bulb is cooled down to the room temperature after the powdered sulfur is completely evaporated and then the bulb is vacuumized and the Ar gas is pumped in the bulb so as to prepare the microwave sulfur lamp bulb. The microwave sulfur lamp bulb prepared by the invention has luminescene spectra similar to the solar spectrum and color rendering index reaching 82. The high vacuum degree and the high-purity sulfur in the bulb outstandingly enhance the service life of the bulb.

The invention relates to an improved microwave sulfur lamp, which comprises a lamp bulb, a lamp handle, a resonant cavity, a magnetron, a waveguide cavity, a motor, a coupling window and a fan. The inner wall of the resonant cavity is provided with two corresponding antenna reclaiming energy structures, and the antenna reclaiming energy structures are in shape of a needle, which causes the microwave energy transferred to the resonant cavity to be more centralized at a central position of the lamp bulb and luminescent substances in the bulb shell of the lamp tube to form the molecular energy level transition under the excitation of higher microwave energy to generate the continuous spectrum; or two corresponding electrodes are arranged on the inner wall of the resonant cavity, and the corresponding electrodes are slices which are in shape of geometry, which causes the central position of the lamp bulb to form the electric field to enhance and stimulate in an assistant way the energy of the luminescent substances in the bulb shell of the lamp tube, thus, the illumination time of the bulb can be shortened, and the problem of one time illumination failure is improved.
