Light distribution lens and LED lamp with same

Abstract

The invention provides a light distribution lens and an LED lamp with the light distribution lens. The light distribution lens comprises a light transmission area, and a light distribution area which is arranged around a central axis of the light transmission area; the light distribution area is equipped with a distributed light incoming surface and a distributed light outgoing surface which are oppositely arranged, wherein the distributed light incoming surface is a plane, comprising a plurality of light incoming rings which are sequentially embedded and distributed on the distributed light incoming surface; the light incoming rings are annular and arranged at intervals; each light incoming ring comprises a plurality of spherical convex surfaces which are sequentially uniformly distributed about the central axis; the spherical convex surfaces of each light incoming ring have the same quantity; the spherical convex surfaces on the same light incoming ring have the same radius. According to the light distribution lens and the LED lamp with the light distribution lens, the plurality of spherical convex surfaces are arranged on the distributed light incoming surfaces of the light distribution lens; a plurality of LED signal lamps transmit light through the plurality of spherical convex surfaces, so that light spots of the plurality of LED signal lamps can be diffused, and as a result, the coverage range of light sources of the LED signal lamps is expanded, the lighting efficiency is increased, and people can conveniently recognize by eyes.

Description

technical field [0001] The invention relates to the lighting field, in particular to a light distribution lens and an LED lamp with the light distribution lens. Background technique [0002] As a new type of green light source product, LED is more and more widely used in the lighting field due to its high luminous efficiency, low power consumption, and long service life. In portable mobile lighting fixtures, such as flashlights, are widely used. Existing LED lamps can not only realize the LED lighting function, but also can match the function of signal lights. [0003] Most of the transparent parts of LED lamps on the market use simple flat glass. Such transparent parts are generally only suitable for LED lamps with only the main light source. For flashlights with signal lights, simple flat glass transparent parts cannot spread the light spots of signal LED lights, so that the coverage of signal lights is narrow, which is not easy. recognized by the human eye.
