In addition, as shown in fig. 3, the other surface of the lens 1 is a frosted surface, so as to eliminate the light spot generated by the light source and homogenize the illumination light.
Specifically, as shown in fig. 5, the distance D between the micro-edge rings 2 is in the range of 0.2mm to 0.65mm.
In addition, as shown in fig. 5, the inclination angle R of the micro-prism 2 ranges from 10 ° to 60 °, and the inclination angle R of the micro-prism 2 is related to the illumination angle of the luminaire light source, and when the inclination angle R of the micro-prism 2 ranges from 10 ° to 60 °, the micro-prism 2 is sufficient to refract the light rays at the extreme edge of the luminaire light source.
Specifically, as shown in fig. 4, the lens 1 corresponds to a region where the light source of the lamp is stronger, the inclination angle R of the micro-prism 2 is smaller, the lens 1 corresponds to a region where the light source of the lamp is weaker, the inclination angle R of the micro-prism 2 is larger, and the micro-prism 2 mainly functions to deflect the light scattered outside the illumination region to the illumination region at the center through refraction, so that, in general, the light source of the lamp is disposed at the center of the lens 1, the illumination region corresponds to the positive direction of the light outlet of the lamp, the light is stronger at the center of the lens 1 and the irradiation direction of the light is in the illumination region, the light is weaker at the edge of the lens 1 and the irradiation direction of the light is mostly deviated from the illumination region, and meanwhile, the smaller the deflection angle R of the micro-prism 2 is after refraction, the larger the deflection angle R of the micro-prism 2 is, and the larger deflection angle R of the micro-prism 2 is the smaller at the center of the plane lens.
