Abstract: |
The light source equipment includes a cathode and an opposite anode. The cathode includes multiple current conducting bearing poles, where there are multiple emitters formed on. The anode possesses several slots in curved face. Multiple current conducting bearing poles with emitters being distributed on are arranged in parallel to constitute array of emitter of cathode. Under action of electric field, emitters emit electron to bomb fluorescent layer on anode so as to radiate light. Thus, energy is converted to light energy directly. Features are: high efficiency for converting energy, no environment pollution. The invention is applicable to multiple areas including illumination. |
