[0019] The technical schemes in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] like Figures 1 to 4 As shown, this utility model provides an emergency lighting polarizing wall washer lens, comprising a long, narrow lens body 1, a light-incident groove 2 at the bottom of the lens body 1, and a light-emitting surface 3 at the top of the lens body 1 for polarization. A portion of the light-emitting surface 3 is atomized. In this utility model, the light-emitting surface 3 allows the LED to transmit light through the optical polarization structure, significantly projecting light onto the target area. The atomized light-emitting surface 3 can soften the yellow ring, achieving a smoother light spot and improving the yellow ring phenomenon during polarization, thereby enhancing the clarity of warning signs.

[0022] The light-emitting surface 3 includes a first curved surface 31, a second curved surface 32, and a third curved surface 33 arranged sequentially adjacent to each other. The second curved surface 32 is a downwardly concave free-form surface. In the height direction, the position of the third curved surface 33 is higher than the position of the second curved surface 32, and the position of the first curved surface 31 is lower than the position of the third curved surface 33. The entire light-emitting surface 3 is a free and irregular curved surface.

[0023] The second curved surface 32 is atomized to form an atomized layer. The surface of the atomized layer of the second curved surface 32 is also provided with a frosted layer, which further lightens the yellow ring and softens the light spot.

[0024] The first curved surface 31 gradually curves upward from the side away from the second curved surface 32 toward the side closer to the second curved surface 32; the third curved surface 33 gradually curves upward from the side closer to the second curved surface 32 toward the side away from the second curved surface 32. From left to right, the light-emitting surface 3 as a whole gradually curves upward, thus forming a polarizing structure.

[0025] The lens is integrally extruded using a two-color extrusion die. One die forms the second curved surface, while the other forms the remaining parts. Compared to traditional injection molds, two-color extrusion dies offer higher cost-effectiveness and faster manufacturing. A two-color extrusion die combines two extrusion modules into a single unit, simultaneously extruding the lens. With two inlet ports, it can extrude two different materials at the same time and then combine them into a complete lens. This invention, using a two-color extrusion die, can integrally form a lens with localized fogging. In contrast, single-material injection molding, with the addition of diffusion, would result in excessive fogging, leading to significant variations in the light spot.

[0026] Mounting protrusions 11 are formed on both the left and right sides of the lens body 1 to enable the mounting of the lens body 1.

[0027] When using, such asFigure 4 As shown, the light emitted by the LED lamp bead is emitted through the light inlet groove 2, and after passing through the lens body 1, it is emitted from the light outlet surface 3, and the design of the whole light outlet surface 3 can greatly project light into the target range (the area where the warning slogan is located), and the ingenious design of the second curved surface 32 can also fade the yellow circle, realize spot softening, improve the yellow circle phenomenon when polarizing, and thus improve the clarity of the warning slogan.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and structures of the utility model, and the scope of the utility model is defined by the appended claims and their equivalent scope.
