A hand-held water purification system in-cludes a pen-light sized ultraviolet lamp (12) that is enclosed in a quartz cover and is powered by a battery and associated ballast circuitry. The bat-tery and ballast circuitry are connected to the lamp by switches that are under the control of a liq-uid-level sensor. The sensor connects the battery, the ballast circuitry and the lamp once the sensor determines that the ultraviolet lamp is fully im-mersed in the water. If the container (32) that holds the water is relatively large, the lamp and quartz cover end (16) of the system are used to stir the water, to ensure that all of the water comes sufficiently close to the ultraviolet lamp (12).

L'invention concerne un dispositif de purification d'eau tenant dans la main, qui comprend une lampe (12) à ultraviolets de la taille d'une lampe-stylo enfermée dans un capuchon en quartz et actionnée par une pile et des circuits de ballast associés. On branche la pile et les circuits de ballast à la lampe au moyen de commutateurs qui sont commandés par un capteur de niveau de liquide. Le capteur met en connexion la pile, les circuits de ballast et la lampe, une fois qu'il a déterminé que la lampe à ultraviolets est entièrement immergée dans l'eau. Si le récipient (32) contenant l'eau est relativement grand, on utilisera la lampe et l'extrémité-capuchon (16) en quartz du dispositif pour remuer l'eau, afin de s'assurer que toute l'eau passe suffisamment près de la lampe (12) à ultraviolets.
