[0020] like Figure 1 , Figure 2 and Figure 3 As shown, an external infrared induction three-proof lamp of the utility model comprises a lamp housing 1 and a lamp shade 2, wherein the lamp shade 2 is arranged at the bottom of the lamp housing 1, and a bottom plate 6 for limiting the lamp shade 2 is arranged on the bottom surface of the lamp housing 1, and a fixing plate 3 is installed at a position on the top surface of the lamp housing 1 opposite to the bottom plate 6, and a first bearing is embedded in one end of the fixing plate 3, and a shaft rod 4 is installed in the inner ring of the first bearing, and the lower end of the shaft rod 4 extends downward along the side of the lamp housing 1 and the lamp shade 2, and is installed on the bottom plate 6, and a gear 5 is installed on the upper end of the shaft rod 4, and a plurality of fixing plates 3 are provided with a rack 9 meshingly connected with the gear 5, and a driving mechanism for driving the rack 9 to move axially is installed on one end of the rack 9, and a longitudinal plate 7 is installed on the top surface of the lamp housing 1, and an infrared sensor 8 for controlling the automatic opening of the three-proof lamp is installed on the bottom surface of the longitudinal plate 7, and the staff can be sensed by the infrared sensor, and the three-proof lamp is automatically turned on, which is convenient for use.

[0021] In this embodiment, the driving mechanism includes a screw 13, a fixed block 12, a second bearing and a gripping rod 14. The fixed block 12 is mounted on the top surface of the lamp housing 1. A mounting hole is provided on the fixed block 12. The second bearing is installed in the mounting hole. A screw hole is provided at one end of the rack 9 opposite to the inner ring of the second bearing. The screw 13 is installed in the inner ring of the second bearing. One end of the screw 13 is threadedly connected to the screw hole, and the other end is fixedly connected to the gripping rod 14.

[0022] In this embodiment, a plurality of fixing seats 11 are installed on the top surface of the lamp housing 1 , and a plurality of fixing holes are provided on the fixing seats 11 .

[0023] In this embodiment, a plurality of positioning posts are protruded from the open end surface of the lampshade 2, and positioning holes are provided on the bottom surface of the lamp housing 1 opposite to the positioning posts. The positioning posts are inserted into the corresponding positioning holes. The lampshade can be positioned front, back, left and right through the inserted positioning posts and positioning holes, thereby avoiding the occurrence of costly and increasing the stability of the installation.
