The beneficial effects of the application are as follows:
1. the polarized optical lens is obtained by adjusting a Bezier curve according to a preset control point and a starting point; through the matched arrangement of the lamp beads and the polarized optical lenses, no light rays are emitted to the right upper part basically, so that the light beams emitted by the lenses do not irradiate in a halving way up and down by 120 degrees and irradiate to the sky in an ineffective way, but are condensed into a thinner light beam of 60 degrees to irradiate to the road surface and pedestrians obliquely downwards; and the lamp beads penetrate through the polarized optical lens and diffuse 110-degree light beams to two lateral sides; when the device is used for realizing close-range viewing, the strength is soft, and dazzling can not be caused; because a thinner light beam condensed into 60 degrees is obliquely downwards irradiated to the road surface and pedestrians, the light beam cannot be clearly seen when being watched in a long distance; compared with the prior art, the method greatly improves the experience of residents.
2.

3. The two lateral sides and the lower part of the polarized optical lens are arranged as planes, which are opposite to the existing straw hat lamp or other easily-formed cambered lenses; because of the problem of assembling the cambered surface, a gap space exists between the cambered surface and the shielding structure at the periphery, namely, a space from the bottom of the cambered surface to a position close to the top, and light rays are transmitted out in the space; part of light becomes an uncontrollable wire harness which cannot be shielded, and the effect finally presented is affected; when the light emitting device is arranged in a plane, the shielding structure of the side part and the required light emitting part of the lampshade can be more close to each other, so that the position where light is not required to be emitted can be removed.

For example, the connection can be fixed connection, detachable connection or integral connection; can be mechanically or electrically connected; can be directly connected, can be connected through an intermediary medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
It is worth noting that, when the applicant researches the present grille screen, the applicant finds that after the present grille screen is installed, people get close to see the glare of eyes; however, the people are far away, and the light scattering causes unclear light, so that a contradiction problem is generated, the visual effect of the grid screen is affected, and the experience of residents is also affected.
As shown in fig. 1 to 13, as an embodiment provided by the embodiment of the present application, there is provided a polarized LED lamp including:
a lamp bead 1 for providing a beam required for external irradiation;
the polarized optical lens 2 is sleeved outside the LED lamp source; the polarized optical lens 2 comprises a polarized optical lens body, and the polarized optical lens 2 is provided with a first mounting groove 202 for accommodating an LED lamp source; the polarized optical lens comprises a semi-elliptic-like part 201 and a light-shielding convex part 203; the light-shielding convex part 203 is a light-shielding concave groove 204 formed by inward concave of one end of the polarized optical lens 2; the other end protrudes outwards to form an elliptical-like part 201; the first mounting groove 202 is shaped as a horn mouth with a narrow inner part and a wide outer part; the lamp beads 1 penetrate through the polarized optical lens 2 to diffuse 110-degree light beams to two lateral sides, and 60-degree light beams are projected to one end, facing the elliptical-like part, of the polarized optical lens 2;
wherein, the length direction of the lamp beads is set to be longitudinal; the direction perpendicular to the longitudinal direction is transverse; the direction perpendicular to the plane in which the transverse direction and the longitudinal direction are located is vertical.
It is worth to say that, when the lamp beads are used, the longitudinal direction is the same as the up-down direction; to further illustrate the orientation of the present application, the semi-elliptical-like portion 201 of the present application is positioned below the light-shielding protrusion 203. The lamp beads 1 are arranged to form a large screen structure which is the most common use form, and the large screen is installed in a state of being basically arranged vertically. The lamp beads 1 penetrate through the polarized optical lenses 2 to diffuse 110-degree light beams to the two lateral sides, and 60-degree light beams are projected to one end of the polarized optical lenses, which faces towards the elliptical part; that is, the lamp beads 1 spread out 110 degrees of the light beam to both sides in the lateral direction through the polarizing optical lens 2, and project 60 degrees of the light beam downward toward the polarizing optical lens 2.
The polarizing optical lens 2 of the present application is a lens having the above-described features.
Specifically, through the cooperation of the lamp bead 1 and the polarized optical lens 2, the light emergent angles are horizontally and bilaterally symmetrical by 55 degrees, only the light emergent range of 60 degrees downwards vertically is reserved, so that the light beams are more converged and condensed in the horizontal direction, the condensed brightness is improved, the light beams emitted by the lens are irradiated to the road surface and pedestrians obliquely downwards, the polarized LED lamp does not irradiate in an upward and downward halving way by 120 degrees and does not irradiate to the sky on the top of the pedestrian, but is condensed into a 60-degree finer light beam to irradiate obliquely downwards directly to the road surface and the pedestrian, the brightness and the intensity of the light beams are obviously improved, the light beams can irradiate to the road surface and the pedestrian obliquely downwards farther, the people can be clearly seen far away, the visual effect of the grid screen is improved, and the experience of residents is also improved.
In addition, the polarized light optical lenses 2 are distributed along the vertical direction array during installation, and the polarized light optical lenses 2 are matched with the lamp beads 1, and the polarized light optical lenses 2 below converge and reflect polarized light beams above; as the viewpoint position moves, the intensity of the light beam decreases when approaching the light source module, and the brightness decreases from the viewpoint of the viewer. When keeping away from the light source module, the module luminance increases to can not produce dizzy sense, have fine visual effect, solve the relatively poor problem of visual effect of present grid screen.
Finally, the light beam emitted along the oblique upper direction is greatly reduced by modulating the light beam through the lens, the brightness and the intensity of the oblique upper direction are obviously reduced, uncomfortable feelings such as dizziness feeling after residents on opposite buildings are basically avoided, and light pollution to the residents on opposite buildings is basically avoided.
