    • A laser level disposable on a reference surface includes a housing, a pendulum pivotably connected to the housing, a first laser diode disposed on the pendulum for emitting a first laser beam along a first path, a first lens disposed on the pendulum in the first path for converting the first laser beam into a first planar beam, the first planar beam forming a first line on the reference surface, a second laser diode disposed on the pendulum for emitting a second laser beam along a second path, and a second lens disposed on the pendulum in the second path for converting the second laser beam into a second planar beam, the second planar beam forming a second line on the reference surface, wherein the first and second lines are substantially perpendicular and non-intersecting.
    • 在参考表面上一次性的激光水平面包括壳体,可枢转地连接到壳体的摆件,设置在摆锤上的第一激光二极管,用于沿第一路径发射第一激光束;第一透镜,设置在第一路径上的摆锤上 用于将所述第一激光束转换成第一平面光束,所述第一平面光束在所述参考表面上形成第一线,设置在所述摆上的第二激光二极管,用于沿着第二路径发射第二激光束;以及第二透镜, 用于将第二激光束转换成第二平面光束的第二路径中的摆锤,第二平面光束在参考表面上形成第二线,其中第一和第二线基本垂直且不相交。
