Abstract

The invention discloses a device and method for measuring the evenness of an LED area array light source, belongs to the field of LED area array light source measuring, and aims to solve the problems that currently a point selecting testing method is used to measure the LED area array light source, the accuracy of the evenness measuring is hard to guarantee, and a large amount of manpower, material resources and time needs to be consumed when the point selecting testing method is used to adjust the LED area array light source. The device comprises a straight-line motion mechanism, a detecting device, an analog signal collector and a control system. The device has the advantages that the light energy of the LED area array light source in the whole irradiating area can be scanned and detected in a short time, and the device is fast in detection, high in efficiency, accurate in processing result and visual in detecting result.

Description

technical field [0001] The invention relates to the field of electromechanical, especially the field of LED area array light source measurement, and specifically relates to a device for measuring the uniformity of an LED area array light source and a measuring method thereof. Background technique [0002] LED area array light source is a new type of energy-saving and environmentally friendly light source, which is widely used in various industries such as light curing, exposure machine, and medical treatment. The LED area light source is generally composed of multiple LED point light sources arranged in a matrix, and its light energy value in a certain irradiation area is the sum of the light energy irradiation or superposition of multiple LED lamp beads, and this The uniformity of light energy in the area depends on the consistency of each LED lamp bead. [0003] Due to the differences in the lamp beads themselves, as well as the existence of processing parts errors and as...
