Embodiment Construction

[0016] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0017] The most critical idea of ​​the present invention is: combine a total internal reflection lens and two or more lenses whose outer surfaces are total reflection surfaces into a variable light distribution lens with multiple total reflection surfaces of different curvatures, and use total reflection surfaces of different curvatures to The reflective surface realizes the change of the light distribution angle.

[0018] Specifically, please refer to figure 1 and figure 2 As shown, the lens with variable light distribution provided by the present invention includes a first lens 1 and more than two second lenses 2 distributed concentrically around the first lens 1, and the first lens 1 is a total internal reflection lens , the outer surface of the second len...

Abstract

The invention relates to light distribution variable lenses and an LED lamp. The lenses comprises a total internal reflection lens (first lens), and more than two lenses (second lenses) whose outer side surfaces are total reflection surfaces. The refractive index of the first lens is equal to the refractive indexes of the second lenses, and the first lens and the second lenses are arranged in a concentric circle manner and are arranged at intervals, so that multiple total reflection surfaces with different curvature are formed. When a light distribution angle needs to be changed, transparent materials with refractive indexes being equal to the refractive indexes of the first and second lenses are put into the gaps between the total reflection surfaces with different curvature, so that light distribution angle can be changed by the use of the total reflection surfaces with different curvature, multiple light distribution effects can be achieved, and complex or special light distribution effect demands can be better met.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a variable light distribution lens and an LED lamp. Background technique [0002] The light distribution system of LED lamps currently on the market is generally a single light distribution system. A single light distribution system consists of a reflector, or a reflector plus a lens, or several lenses, such as a Chinese invention patent with the patent application number 200980162797.2 and the patent name "LED light distribution device, LED lamp and LED device" . This single light distribution system can only achieve a single light distribution effect, and cannot meet the requirements of more complex or special light distribution effects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a variable light distribution lens and an LED lamp. [0004] In order to solve the above-mentioned technical problems, the techni...
