    • 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.
    • 一种便携式照明装置(10),包括发射器模块和光学聚焦装置(15),所述发射器模块配备有用于发射光束的至少一个发光二极管(11),用于固定和连接所述二极管的元件(12) 在二极管(11)的前方移动以改变光束的显示角度。 光学聚焦装置(15)有利地包括安装在枢转支撑件(17)上的一个或多个菲涅耳透镜(16)或旋转按钮,该按钮可以放置在位于二极管的光发射场外部的非激活位置,或者放置在 其中光束流过透镜以获得宽范围的短程照明或窄范围的远距照明。
