    • The present invention relates to a field emission lighting arrangement, comprising an evacuated envelope inside of which an anode structure comprising a phosphor layer and afield emission cathode are arranged,the anode structure being configured to receive electrons emitted by the field emission cathode and to generate light when a voltage is applied between the anode structure and the field emission cathode, wherein the evacuated envelope comprises a light exit portion and a light reflective portion being adapted to reflect light generated at the anode structure, and the field emission lighting arrangement further comprises a heat sink arranged outside of the evacuated envelope and thermally coupled to the light reflective portion. Advantages with the invention includes increase lifetime of the field emission lighting arrangement.
    • 本发明涉及一种场致发射照明装置,包括一个抽真空的外壳,其中布置了一个包括一个荧光体层和一个外部发射阴极的阳极结构,该阳极结构被配置为接收由该场发射阴极发射的电子并产生光 当在阳极结构和场发射阴极之间施加电压时,其中抽真空的外壳包括光出射部分和适于反射在阳极结构处产生的光的光反射部分,并且场发射照明装置还包括热 水槽布置在真空外壳的外部并热耦合到光反射部分。 本发明的优点包括增加场发射照明装置的寿命。
