    • PROBLEM TO BE SOLVED: To provide a light-emitting device of lower power consumption, higher light emission efficiency, and longer life. SOLUTION: The light-emitting device includes an airtight container 1 in which a xenon gas is sealed up, an electron source 2 for applying electrons into the airtight container 1 for exciting the xenon gas, an anode electrode 3 arranged to face the electron source 2 in the airtight container 1, a phosphor layer 4 which is arranged on the inner surface side of the airtight container 1 and is excited for emission by the excitation light consisting of the light radiated during an emission process of the excited xenon gas, and a control device 5 for controlling a voltage between a surface electrode 27 of the electron source 2 and a lower electrode 25 (between drive electrodes) as well as a voltage between the anode electrode 3 and the electron source 2. The control device 5 controls the voltage between a surface electrode 27 of the electron source 2 and the lower electrode 25 so that the peak energy in energy distribution of electrons comes to be larger than the excitation energy of the xenon gas but smaller than the ionized energy of the xenon gas. Thus, the xenon gas is excited without discharging it. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供低功耗,更高发光效率和更长寿命的发光装置。 解决方案:发光器件包括密封氙气体的气密容器1,用于将电子施加到用于激发氙气体的气密容器1中的电子源2,阳极3布置成面对 气密容器1中的电子源2,配置在气密容器1的内表面侧的荧光体层4,被激发的激发光激发,该激发光由在被激发的氙气的发射过程中辐射的光组成, 以及用于控制电子源2的表面电极27和下部电极25(驱动电极之间)之间的电压以及阳极电极3和电子源2之间的电压的控制装置5.控制装置5控制 电子源2的表面电极27和下部电极25之间的电压使得电子的能量分布中的峰值能量大于 氙气,但小于氙气的电离能。 因此,氙气被激发而不会放电。 版权所有(C)2010,JPO&INPIT
