Description

Technical Field

[0002] In the production or inspection process of many products, there will be high requirements for ambient light sources, and at this time, some auxiliary light sources are needed. For the lighting inspection of objects with reflective surfaces, the market is currently dominated by plane light sources. When plane light sources illuminate objects with reflective surfaces, the reflective surfaces will reflect light, which will affect observation. At this time, it is necessary to use diffusely reflected light sources to reduce the reflection on the surface of the object being measured, so as to effectively reduce the impact of the reflection of the object being measured. Therefore, we designed a light source that can evenly illuminate objects with reflective surfaces. Utility Model Content
