UV LED point light source curing machine is also called ultraviolet led point light source. It is a kind of LED curing lamp that can emit ultraviolet light. By irradiating some special uv photosensitive materials, a photochemical reaction is generated to realize the rapid curing of uv glue or ink. So what should you pay attention to when choosing a UV LED point light source? Today, I will give you a brief introduction.
The parameters of the uvled point light source curing machine need attention
1. [Spot size] The aperture size of the irradiation head of the uvled point light source curing machine under a certain irradiation distance. The size of the lens spot can be selected from 1.5mm-20mm;
2. [Light intensity] The light intensity of the uvled point light source curing machine-the ultraviolet light density is less than the light intensity per square centimeter, usually the light intensity is between 600mW/cm² and 10000mW/cm²;
3. [Illumination distance] The distance between the irradiation head of the uvled light source and the surface of the object to be irradiated, usually the irradiation distance of the point light source is controlled between 10-50mm;
4. [Lamp bead selection] The lamp beads of the uvled point light source curing machine on the market are divided into domestic lamp beads and imported lamp beads. At present, most of the better LED point light source chips used by domestic manufacturers are our lamp beads, and the light source is stable. , The service life is as long as 30,000 hours;
5. [uv glue parameters] When choosing a uvled point light source curing machine, you need to confirm the amount of energy required for glue curing, such as 1000mj of glue, you can use 1000mW/cm² point light source for irradiation, uv glue is about 1 second The curing can be completed;
