    • A method and apparatus for retrofitting a backlit sign with an LED module. The housing includes sidewalk with translucent portions. The LED module includes linear arrays of LEDs supported by support arms having mounting mechanisms for engaging with the housing sidewalk. The mounting mechanisms include scissor anus rotatably attached together about mid-portions thereof, and a tightening screw that adjusts the distance between the scissor arm ends to press engagement surfaces of the scissor arms against the housing sidewalk. Adjustment screws at the lower ends of the support arm can be adjusted to further extend the engagement surfaces, so that a single LED module can be installed inside a wide range of backlit sign sizes. The retrofit method includes removing the conventional fluorescent lamp from the backlit sign, and installing the LED module using the scissor arm mounting mechanisms.
    • 一种用LED模块改装背光标牌的方法和装置。 外壳包括具有半透明部分的人行道。 LED模块包括由支撑臂支撑的LED的线性阵列,所述支撑臂具有用于与外壳人行道接合的安装机构。 安装机构包括围绕其中间部分可旋转地连接在一起的剪刀肛门,以及调节剪刀臂端部之间的距离以将剪刀臂的接合表面压靠在外壳人行道上的紧固螺钉。 可以调整支撑臂下端的调整螺钉以进一步延伸接合表面,从而可以将单个LED模块安装在各种背光标志尺寸内。 改装方法包括从背光标牌上拆下传统荧光灯,并使用剪刀臂安装机构安装LED模块。
