Abstract: This invention relates to a means for more efficiently and more safely providing self-luminous lighting devices for use in signs, markers, indicators and the like. Said invention provides self luminosity by means of a plurality of glass microspheres containing both a light emitting phosphor and a radioactive gas. The "soft" emission of electrons from the beta emitting gas can not penetrate the glass wall of the microspheres, thereby constituting no radiation hazard. The containment of the self-luminous system within an envelope which does not pass any radiation prevents the deterioration of nearby organic materials. A further advantage of said invention is that the plurality of individual containment envelopes minimize the escape of radioactive gas in the event of any physical damage to an assembly of such envelopes. A still further advantage of my invention is that the radioactive gas completely surrounds the phosphor particles, thus causing light emission from 100 percent of the surface of said particles.

Abstract translation: 本发明涉及一种用于更有效和更安全地提供用于符号，标记，指示器等的自发光照明装置的装置。 所述发明通过含有发光荧光体和放射性气体的多个玻璃微球提供自发光。 来自β发射气体的电子的“软”发射不能穿透微球的玻璃壁，从而不产生辐射危害。 在不通过任何辐射的封套内的自发光系统的容纳可防止附近有机材料的劣化。 所述发明的另一个优点是，在对这种信封的组件进行任何物理损坏的情况下，多个单独的容纳封套使放射性气体的逸出最小化。 我的发明的另一个优点是放射性气体完全围绕荧光体颗粒，从而引起来自所述颗粒表面100％的光发射。
