Abstract
The utility model discloses a machine vision LED (Light-Emitting Diode) light source, which comprises a base and matrix light source components installed on the base, wherein each matrix light source component comprises two supports and an LED matrix light source movably installed between the two supports; the number of the matrix light source components is ten, and the matrix light source components are installed on the base according to a regular decagon; and the LED matrix light sources are connected with a controller. The illumination surface of each LED matrix light source is provided with a diffusion panel, and the light becomes uniform through the diffusion effect of the diffusion panels. Compared with the current ring light source, the machine vision LED light source can obtain more abundant brightness and incident angles under the condition that a lampshade does not move, and the light is uniform. Thus, the machine vision LED light source can be suitable for more application occasions and can also uniformly light different sizes of measured objects so as to cause the characteristics of the objects to be obvious as much as possible.
