Abstract

The invention discloses a light emitting diode (LED) lamp lens, which comprises a collimation lens, wherein the side face of the collimation lens is a total reflection face; a light outlet face of a sheet lens consists of convex faces of triangular convex lenses and concave faces of triangular concave lenses; and the collimation lens is provided with a refraction groove at an end plane opposite to the light outlet face of the collimation lens. Through the combination of the collimation lens and the sheet lens, the LED lamp lens is applicable to different LED chips and is more universal; and light which is emitted by the LED lamp lens is distributed uniformly and softer.

Description

technical field [0001] The invention relates to the field of LED lighting equipment, in particular to an LED lamp lens. Background technique [0002] A light-emitting diode (Light-Emitting-Diode, referred to as LED) is a semiconductor that can convert electrical energy into light energy, and its core component is an LED chip. [0003] As a high-profile new-generation light source, LED has many advantages such as small size, large luminous flux, all-solid-state operation, compact structure, green and pollution-free, high efficiency, and energy saving. However, because its typical light output characteristic is a half-space Lambertian light source, direct application is likely to cause shortcomings such as unreasonable brightness distribution and glare. Therefore, secondary light distribution technology is usually used in lighting applications to redistribute light. Various LED optical lenses have become the most Ideal secondary light distribution technology. [0004] At pre...
