[0003] In view of this, the utility model aims to provide a mixed-light floodlight lens for warning, which can optimize light dispersion and homogenize light spots by making a V-groove structure at the bottom of the lens. The R value of the tip of the V-groove and the arrangement of the number of teeth will indirectly affect the distribution of light tracing and thus reduce the uneven light spot superposition caused by the mixed-light LED projected onto the lens. The local compound eye dots can further optimize the mixed light effect. Utility Model Content

By making a V-shaped groove structure at the bottom of the lens, the light dispersion can be optimized and the light spot can be homogenized. The R value of the tip of the V-shaped groove and the arrangement of the number of teeth will indirectly affect the distribution of light tracing and thus reduce the uneven light spot superposition phenomenon caused by the mixed light LED projected onto the lens. The local compound eye dots can further optimize the mixed light effect.

[0005] In order to solve the above defects of the prior art, the technical solution provided by the utility model is:

[0006] A mixed light floodlight lens for warning includes a lens body and a mounting structure surrounding the lens body, wherein a plurality of compound eye dots are formed in the central area of ​​the lower surface of the lens body, and a plurality of V-shaped grooves extending from the edge of the central area to the edge of the lens body are also formed on the lower surface of the lens body.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0023] As Figures 1 to 5 shown, a warning mixed-light floodlight lens provided by the present utility model includes a lens body 1 and an installation structure 2 surrounding the lens body 1. A plurality of compound eye dot patterns 3 are formed in the central area of the lower surface of the lens body 1, and a plurality of V-shaped grooves 4 extending from the edge of the central area to the edge of the lens body 1 are further formed on the lower surface of the lens body 1. The bottom of the lens body 1 is an upwardly arched arc surface.

[0024] Among them, the V-shaped grooves 4 can optimize light dispersion and homogenize the light spot. The size of the tip R value and the tooth number arrangement of the V-shaped grooves 4 will indirectly affect the distribution of light tracing, thereby weakening the phenomenon of uneven superposition of light spots caused by the mixed-light LED projected onto the lens. The local compound eye dot patterns 3 can further optimize the mixed-light effect. That is, the combination of the two microstructures of the V-shaped grooves 4 and the compound eye dot patterns 3 in the present utility model realizes the light homogenization effect, thereby optimizing the mixed-light effect on the light source LED.

[0025] The tip R value of the V-shaped groove 4 is 0.05 - 0.2 mm to weaken the phenomenon of uneven superposition of light spots caused by the mixed-light LED projected onto the lens.

[0026] The angle of the V-shaped groove 4 is 30° - 120°.

[0027] A downwardly protruding flange portion 5 is further provided between the lens body 1 and the installation structure 2 to prevent light from leaking out from the edge.

[0028] A plurality of mounting posts 21 are provided on the bottom surface of the installation structure 2. A plurality of mounting grooves 22 are formed at the edge of the installation structure 2 for mounting the entire lens onto a light source.

[0029] The area ratio of the area where the compound eye dot patterns 3 are located to the area where the V-shaped grooves 4 are located is 1:(3 - 8).

[0030] When in use, as Figure 5 shown, the light emitted by the LED hits the bottom of the lens body 1. The light incident on the area of the compound eye dot patterns 3 is refracted by the compound eye dot patterns 3 and is divided into multiple beams of light that are evenly emitted from the top of the lens body 1; the light incident on the area of the V-shaped grooves 4 is refracted by the V-shaped grooves 4 and is divided into multiple beams of light that are evenly emitted from the top of the lens body 1.

[0031] The present utility model can optimize light dispersion and homogenize the light spot by making the V-shaped groove 4 structure at the bottom of the lens. The size of the tip R value and the tooth number arrangement of the V-shaped groove 4 will indirectly affect the distribution of light tracing, thereby weakening the phenomenon of uneven superposition of light spots caused by the mixed-light LED projected onto the lens. The local compound eye dot patterns 3 can further optimize the mixed-light effect.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and structures of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalent scope.
