    • A lighting apparatus is provided that includes a magnetron configured to generate microwaves having a predetermined frequency, a waveguide including a first wave guide space configured to introduce and guide the microwaves and a second wave guide space expanded from the first wave guide space, a resonator to which the microwaves are transmitted from the waveguide and a bulb located in the resonator, the bulb encapsulating a light emitting material and being configured to emit light in response to the transmitted microwaves. The second wave guide space is located in a transmission path of the microwaves transmitted from the magnetron to the resonator.
    • 提供了一种照明装置,其包括被配置为产生具有预定频率的微波的磁控管,包括被配置为引导和引导微波的第一波导空间的波导和从第一波导空间扩展的第二波导空间, 所述微波从所述波导传播并且所述灯泡位于所述谐振器中,所述灯泡封装发光材料并且被配置为响应于透射的微波而发光。 第二波导空间位于从磁控管传输到谐振器的微波的传输路径中。
