Prevent light scattering from shining into the eyes of the staff, greatly improve the lighting safety; and the three groups of LED light modules 81 are linearly arranged to irradiate, so that the lighting area range is wide, and the irradiation light is mutually superimposed and supplemented, so that the brightness of the entire lighting area is more uniform, thereby avoiding obvious brightness difference.
[0039] The bottom of the concave foot 11 and the bottom of the floodlight main shell 1 have a height difference, so that the floodlight main shell 1 has a gap with the ground of the heliport. The natural terrain is utilized, so that the rainwater can flow smoothly through the gap to the low place when it rains, effectively avoiding the problem of water accumulation caused by the obstruction of rainwater at the position of the floodlight;
[0040] Secondly, the convex ring 12 is arranged at the top of the floodlight main shell 1 to form a waterproof barrier. When the rainwater seeps into the inside from the gap of the upper cover 2, the rainwater is blocked and difficult to enter the inside of the installation chamber due to the fact that the convex ring 12 is higher than the top of the floodlight main shell 1, so the waterproof performance is high;
[0041] The floodlight is located between the lampshade glass 3 and the installation groove 15, and the rubber waterproof ring 7 is installed, so as to improve the sealing performance and prevent water from entering. Moreover, the bottom of the installation groove 15 and the bottom of the lighting groove 16 have a height difference, which effectively blocks the rainwater from entering the installation chamber, realizes double waterproof, and finally, the condensing convex mirror 6 is inserted between a group of reinforcing rib structures 14, that is, between two L-shaped ribs 141 and a right-angle rib combination, to block the channel of the lighting groove 16, realize triple waterproof, and have high waterproof performance;
[0042] In summary, the floodlight is designed with multiple waterproof designs, effectively solving the problem of easy erosion of outdoor lighting by rainwater. The waterproof performance is excellent, not only protects the internal electronic elements of the floodlight from being damaged, but also prolongs the service life and improves the lighting effect. At the same time, these designs also reduce the maintenance cost and provide a more reliable and efficient lighting solution for the outdoor lighting field.
