Problems solved by technology

However, in the secondary optical design of LED lighting applications, due to the lighting angle, most of the light emitted by the LED is directly irradiated without reflection, which will inevitably cause a large loss of LED light energy

Abstract

The invention discloses a lens, which is a floodlight lens and includes a light incident surface, a positioning surface, a first light emergent surface, a light reflecting surface and a second light emergent surface, wherein the light incident surface, the positioning surface, the first light emergent surface, the light reflecting surface and the second light emergent surface are sequentially connected; the positioning surface is perpendicular to an optical axis direction; a part of light injecting into the light incident surface is injected into the second light emergent surface after being refracted, or a part of light injecting into the light incident surface is injected into the light reflecting surface after being refracted and then is injected into the first light emergent surface after being refracted by the light reflecting surface; the light refracted by the first light emergent surface and the second light emergent surface are overlapped with each other and then shot out. The invention also provides an LED lamp provided with the lens assembly. The light distribution system of the LED lamp is constituted by the lens assembly, the emergent light with large illumination surface and uniformly transited illumination is formed, and the requirement of the LED lamp on the light distribution design is met.

Description

technical field [0001] The present invention relates to the lighting field, in particular to a lens assembly and an LED (light emitting diode, light emitting diode) lamp using the lens assembly. Background technique [0002] As a semiconductor that can convert electrical energy into light energy, LED is widely used in various lighting fixtures due to its advantages of high efficiency, low energy consumption, and long life. Indispensable lighting equipment. These lamps generally include housing, light source, reflector, lampshade and other components, the light source and reflector are installed in the housing, the reflector can reflect the light emitted by the light source, and the lampshade is installed on the housing , and the light source and the reflector are packaged in the housing, the light emitted by the light source and the light reflected by the reflector are projected out by the lampshade. [0003] Different from traditional light sources such as incandescent la...
