[0030] Example

[0031] like Figure 1-8 As shown, this utility model provides a curved, wave-shaped light-shielding structure for a street lamp lens, including a lens body 1. The upper surface of the lens body 1 has several parallel arc-shaped protrusions 2. One side of each arc-shaped protrusion 2 has a chamfered surface 3, on which several wave-shaped structures 4 are arranged. The lower surface of the lens body 1 has several light-entry holes 5, and an LED lamp 6 is placed inside each light-entry hole 5. The arc-shaped protrusions 2 correspond one-to-one with the light-entry holes 5. Figure 7-8 As shown, in use, the arc-shaped protrusion 2 and the wave-shaped structure 4 can increase the amount of light scattered to both sides, increase the proportion of light scattered to both sides, reduce the proportion of light emitted in the direct direction, avoid the effect of direct light, improve light utilization, and achieve the purpose of increasing light blocking. Specifically, the light emitted by the LED lamp 6 is refracted by the wave-shaped structure 4 on the beveled surface 3 and then emitted from above, preventing light from escaping from the side of the light entrance hole 5 and preventing light leakage. In other words, existing ultra-wide-angle lens designs will have direct light leakage at the edges. This utility model cleverly designs a wave-shaped light-blocking structure on the optical surface on the side of the light leakage to reduce the effect of direct light leakage from the front at a distance of 180 degrees, thereby reducing glare.

[0032] The bottom surface of the arc-shaped protrusion 2 is elliptical, and the outer surface of the arc-shaped protrusion 2 is a free-form surface. This can increase the amount of light scattered to both sides.

[0033] The light entrance aperture 5 is recessed into the lens body 1, and the surface of the light entrance aperture 5 is an arc-shaped curved surface.

[0034] The opening of the light inlet 5 is elliptical, and the long axis of the light inlet 5 is perpendicular to the long axis of the arc-shaped protrusion 2.

[0035] The light entrance aperture 5 is positioned directly below the corresponding arc-shaped protrusion 2, and the surface of the light entrance aperture 5 is a free-form surface. The curved surface design of the light entrance aperture 5, combined with the irregular lens, achieves a better light-blocking effect.

[0036] The profile of the oblique surface 3 includes a straight bottom edge 31, two curved sides 32, and a curved top edge 33. The curved sides 32 and the curved top edge 33 are formed by connecting several wavy edges.

[0037] The extension direction of the wave-shaped structure 4 is parallel to the long axis of the arc-shaped protrusion 2. That is, the extension direction of the undulating wave-shaped structure 4 is parallel to the long axis of the arc-shaped protrusion 2, which facilitates the refraction of light and prevents light leakage.

[0038] The lens body 1 is treated with a frosting process. The wave-shaped design and frosting process in this invention prevent light from directly illuminating the LED spot and increase its aesthetic appeal.

[0039] In summary, this utility model has at least the following advantages:

[0040] First, the arc-shaped protrusion 2 and the wave-shaped structure 4 can increase the light scattered to both sides, avoid the effect of direct sunlight, improve the light utilization rate, and achieve the purpose of increasing light blocking.

[0041] Second, it achieves both optical and aesthetic effects;

[0042] Third, the combination of the arc-shaped protrusion 2 and the wave-shaped structure 3 with the curved surface design of the light inlet reduces the number of light spots that are directly visible to the naked eye.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and structure of the present invention, the scope of which is defined by the appended claims and their equivalents.
