    • A portable lighting lamp comprises an emitting module equipped with at least one light-emitting diode for emitting a light beam, a fixing and connecting element of said diode, and an optical focusing device able to be moved in front of the diode to make the visualization angle of the light beam vary. The optical focusing device is advantageously constituted by one or more Fresnel lenses mounted on a swiveling support or a rotary knob designed to occupy either an inactive position situated outside the light emission field of the diode or an active position wherein said light beam passes through the lens so as to obtain either broad lighting with a short range or narrow lighting with a long range.
    • 便携式照明灯包括配备有用于发射光束的至少一个发光二极管的发光模块,所述二极管的固定和连接元件以及能够在二极管的前方移动以形成可视化的光学聚焦装置 光束的角度不同。 光学聚焦装置有利地由安装在旋转支架上的一个或多个菲涅耳透镜或设计成占据位于二极管的发光场外的非活动位置或其中所述光束通过透镜的活动位置的旋钮 以获得具有短距离的宽光照或具有远距离的窄光照明。
