Embodiment Construction

[0074] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0075] It should be noted that: in the present invention, the lens group can be applied to different LED single lamp light sources, it can be a primary mold lens for packaging LED, or it can be a secondary optical lens added to a packaged LED. The invention mainly illustrates the combination realization of lens groups.

[0076] One of the main ideas of the present invention may include: the lens group can realize that the light emitted by the center of the LED...

Abstract

The invention discloses a light emitting diode (LED) light source, which comprises a lens group. The lens group is arranged on a fixed LED light source component, and comprises a plurality of lenses. The lenses are unimodal lenses and / or multimodal lenses. The lens group is used for regulating the orientation of light emitted from the LED light source. According to the LED light source, much blue light in a first angle region and much yellow light in a second angle region are converged in a certain direction by the lens group, and are mixed and emitted from a certain direction of the lens group, so that remarkable blue light spots formed in the first angle region and remarkable yellow light spots formed in the second angle region are eliminated. When the LED light source is applied to street illumination, the blue light spots or the yellow light spots in a road illumination region are effectively eliminated, and the problem of non-uniform light color distribution of the light spots in the road illumination region is solved.

Description

technical field [0001] The present invention relates to the technical field of LED (Light Emitting Diode, light-emitting diode) lighting, and more specifically, relates to an LED light source. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is easy to realize various forms of light distribution, and a corresponding LED light source can be formed through a primary light distribution process and a secondary light distribution process. In the application of street lighting, because the LED light source street lamp has a reasonable light distribution form, most of the light generated by it is directed to the direction of lighting utilization value, reducing unnecessary light waste and improving the utilization rate of lighting flux. Therefore, LED light source street lamps have been vigorously promoted. and development. [0003] The primary light distribution process of LED in the prior art is to package the bimodal lens on the packaging bracket i...
