Embodiment Construction

[0028] For the convenience of those skilled in the art to understand, below in conjunction with embodiment and appended Figure 1-2 To further illustrate the present invention, the content mentioned in the embodiment is not to limit the present invention.

[0029] See Figure 1-2 , a light focusing reflector, the reflector 4 includes a plurality of elliptical off-axis reflector units with different radii of curvature, and the plurality of elliptical off-axis reflector units focus the light emitted by the LED chip 30 to a focal point 40. The reflective surface of each elliptical off-axis reflector is a curved surface, and the curved surface conforms to the quadratic surface formula: ,in, K is the quadratic surface coefficient, R is the radius of curvature, C 2 =X 2 +Y 2 , X, Y, Z are coordinates with the focal point 40 as the coordinate origin.

[0030] The reflector of the present invention can converge the light emitted by the LED chip from multiple angles to a foc...

Abstract

The invention relates to three-dimensional feature detection in the field of machine vision, particularly to a reflector for focusing light rays. The reflector comprises a plurality of oval off-axis reflector monomers with different curvature radii, the light rays sent from an LED chip are focused into one focal point through the oval off-axis reflector monomers, the reflecting surface of each oval off-axis reflector monomer is a curved surface, and the curved surfaces conform to a quadric surface formula in the following drawing, wherein K is the quadric surface coefficient, R is the curvature radius, C<2> is equal to the sum of X<2> and Y<2>, and X,Y and Z are the coordinates using the focal points as the original points of the coordinates. According to the reflector, the light rays sent from the LED chip can be reflected by the reflector to be focused into one focal point, so that the three-dimensional feature detection in the field of the machine vision can be realized, and besides, the aspherical reflector is adopted to realize the high energy utilization ratio.

Description

technical field [0001] The invention relates to three-dimensional feature detection in the field of machine vision, in particular to a light focusing mirror. Background technique [0002] The existing detection lamps used in the field of machine vision are realized by a strip-shaped LED light. The light emitted by the strip-shaped LED light is a straight line, which can only be used for two-dimensional feature detection in the field of machine vision, and the detection effect is not good. Good, and low energy efficiency. Therefore, it is necessary to develop a mirror for three-dimensional feature detection in the field of machine vision. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a light focusing reflector, which can converge the light emitted by the LED chip to a focal point from multiple angles, so as to realize the advantages and disadvantages in the fiel...
