    • A portable lighting device (10) comprising an emitter module fitted with at least one light emitting diode (11) for emitting a light beam, an element (12) for fixing and connecting said diode, and an optical focusing device (15) which can be displaced in front of the diode (11) in order to vary the display angle of the light beam. The optical focusing device (15) advantageously comprises one or several Fresnel lenses (16) mounted on a pivoting support (17) or a rotary button which can be placed in an inactivated position located outside the light emission field of the diode or placed in an activated position wherein the light beam flows through the lens in order to obtain broad short-range lighting or narrow long-range lighting.
    • 便携式光源(10)具有发射光束的电致发光二极管(11),用于二极管的支撑(12)和连接,以及可以在二极管的前面移动的光学屏幕(15) 改变光束的发散角度。 光学装置携带安装在板(17)上的一个或多个菲涅尔透镜(16),该透镜可以在二极管的前面移动。
