The invention relates to a sunlight-resistant light curtain which comprises a frame body and a light filtering bar. The cross section of the frame body is in a rectangular shape; one end of the framebody is opened and is fixed with the light filtering bar in a fastening way; plug-in bars are arranged at the positions, on the opening part, on two side walls of the frame body; hooked fastening barsare arranged on the outer sides of the end parts of the plug-in bars; plug-in grooves for the corresponding plug-in bars to plug in are symmetrically formed in two ends of one side of the light filtering bar; upward locking fastening bars are arranged at the lower ends of the outer side walls of the plug-in grooves and are fastened with the hooked fastening bars; an infrared pipe chip is fixed onto one side wall of the inner part of the frame body in a clinging and clamping way; infrared receiving/transmitting pipes facing the light filtering bar are uniformly arranged on one side of the infrared pipe chip; and the thickness of the light filtering bar is not smaller than 6 mm. The sunlight-resistant light curtain provided by the invention is simple in structure, the thicknesses of a lightfiltering plate and the infrared pipe chip are improved, the installation structures of the light filtering plate and the infrared pipe chip are correspondingly changed, and the sunlight resistance of the light curtain is greatly improved.

    本发明涉及一种抗阳光光幕,包括框体和滤光条,框体的截面呈矩形,其一端开口且扣接固定有滤光条,框体的两侧侧壁在开口处设置有插接条,插接条的端部外侧设置有钩形扣条,滤光条的一侧两端对称设置有供相对应的插接条插入的插接槽,插接槽的外侧侧壁的下端设置有朝上的锁紧扣条,该锁紧扣条与钩形扣条相扣,框体的内部一侧侧壁上紧贴卡接固定有红外线管芯片,红外线管芯片的一侧均匀排列有朝向滤光条的红外线接收/发射管,滤光条的厚度不小于6mm。本发明结构简单,提高了滤光片和红外线管芯片的厚度并相应地改变了滤光片和红外线管芯片的安装结构,大大提高了光幕的抗阳光性能。
