However, the light-emitting surface of the light distribution lens is basically a horizontal plane. In order to use the side wall of the light distribution lens to reflect and converge light, the height of the horizontal plane, that is, the thickness of the lens, needs to be set relatively high, which wastes a lot of material.

The invention relates to the field of illumination and discloses a lens for adjusting a light emission path of a light source, wherein one lens monomer comprises a middle path light adjusting part and side path light adjusting parts, wherein the middle path light adjusting part is positioned at the middle, and the side path light adjusting parts are connected with the middle path light adjusting part and are positioned at the middle path light adjusting part; the middle path light adjusting part is formed by two connected sidewalls; the included angle formed by connection of the two sidewalls of the middle path light adjusting part is smaller than 90 degrees so that the middle path light adjusting part is of an included angle-shaped shell structure extending towards a direction far away from the LED (Light-Emitting Diode) light source; each side path light adjusting part is obliquely arranged opposite to the plane where the LED light source is positioned; each side path light adjusting part is of a plate-shaped structure and comprises an inner side surface and an outer side surface, wherein the inner side surface is arranged towards the middle path light adjusting part, and the outer side surface is arranged far away from the middle path light adjusting part. The invention also discloses an illuminating module and an illuminating lamp comprising the lens. The illuminating module and the illuminating lamp disclosed by the invention are used for illumination and are capable of adjusting the light emission path so as to obtain a relatively-uniform illumination light type similar with a butterfly shape.
Description
technical field [0001] The invention relates to the field of lighting, in particular to the field of LED lighting, in particular to the improvement of a lens for sorting out the light paths of LEDs. Background technique [0002] Arranging the outgoing light path of LEDs to obtain the expected light pattern is one of the necessary technical cores in the research and development of LED lighting. For example, Chinese Patent Publication No. CN102401319B proposes an LED light distribution lens. However, the light-emitting surface of the light distribution lens is basically a horizontal plane. In order to use the side wall of the light distribution lens to reflect and converge light, the height of the horizontal plane, that is, the thickness of the lens, needs to be set relatively high, which wastes a lot of material. . Contents of the invention [0003] Therefore, the present invention proposes an improved lens and a lighting module using the lens, which can achieve the techn...
