Lens component and led lamp with the lens component

Abstract

A lens assembly, used for optically processing and emitting light from an LED light source, is characterized in that the lens assembly includes a first curved surface, a second curved surface and an embossed surface; the first curved surface is a spherical crown surface and The second curved surface is located on the outside of the lens assembly, and is used for the light emitted by the LED light source to exit; The embossed surface connects the first curved surface and the second curved surface. The present invention also provides an LED lamp using the above-mentioned lens assembly. In the above-mentioned LED lamp, after the light emitted by the LED light source is optically processed by the lens assembly, the LED lamp has a larger flood angle, which improves the utilization rate of light, and has a better flood effect, which meets the lighting requirements. The required uniformity and average illumination.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a lens assembly and an LED (light emitting diode, light-emitting secondary light) lamp with the lens assembly. Background technique [0002] Most of the existing surround-illuminated floodlight LED lamps use reflective cups for light distribution. However, the use of reflective cups for light distribution will lead to greater light intensity along the LED optical axis, so the light distribution of reflective cups Floodlight always has a high light intensity in the middle part. In order to solve the problem of high light intensity in the middle part, dense small bumps (or concave holes) are often made on the exit surface of LED lamps to achieve the floodlight effect, or the exit surface friction treatment is used to achieve floodlight. However, the floodlight effect achieved by these processing methods is not uniform enough, and the floodlight angle is generally small, and the utilization...
