Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Such as Figure 1~5 , the embodiment of the present invention provides an LED light distribution lens, including a transparent body, the body has a first surface 10, a second surface 20, a light incident surface 30 and an internal reflection surface 40; the light incident surface 30 is in the shape of a ring Or a regular polygonal ring, the regular polygonal ring means a ring composed of regular polygons with two coincident center points and equal sides and different sizes. The first surface 10 is formed by extending from the outer edge of the light incident surface 30 and facing away from ...

Abstract

The invention relates to the optical field and provides an LED light distribution lens. The LED light distribution lens comprises a transparent body, wherein the transparent body is provided with a first surface, a second surface, a light incoming surface and an inner reflection surface; the light incoming surface is ring-shaped or polygonal-ring-shaped and extends out of the outside of the light incoming surface along the backward direction to form the first surface; the light incoming surface is formed by angularly splicing a plurality of polygonal surfaces in the surrounding direction of the light incoming surface; the edge of the inner reflection surface is butted with the inner edge of the light incoming surface, is sunken inwardly and is formed by angularly splicing a plurality of polygonal surfaces; light incoming slots are formed in the light incoming surface. The lens is capable of reflecting the incoming light for a plurality of times and shooting the light at a plurality of angles, so that the light cannot be shot into the human eyes, the light source cannot be directly seen, and the light is natural; the light is repeatedly reflected to form various angles and is refracted out in various positions; the light splitting effect is excellent; the light is bright and colorful and is large in visual range.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to an LED light distribution lens and an LED lighting device. Background technique [0002] With the continuous development of LED technology, its cost has been continuously reduced while its performance has been continuously improved. Lighting and decorative devices using LED as a light source have been widely used, and a sub-category of products has been formed. As a point light source for decorative lighting, in order to achieve a 180° veneer luminous effect, most designers now use lenses to diffuse the luminous angle of the LED light source to achieve it. The light is directly incident from the bottom curved surface and then transmitted through the light-emitting facet. The light distribution angle can be very large to achieve large-angle coverage, and the light-emitting facet can achieve a partial sparkle effect. However, due to the small refractive index of the lens, the angle of...
