How to choose the right UV LED spotlight source?

UV LED spot light source is small in size, has strong flexibility, and can be used with multiple irradiation heads according to the demand, especially suitable for optical communication, electronic components, precision instruments, and other industries, compared to UVLED line light source and area light source is popular with users! So how to choose the right UVLED spot light source?

Structure of UV LED spot light equipment

UV LED spot light equipment is mainly composed of the controller, the irradiation head & lens , among which, UVLED spotlight controller is the standard product, irradiation head size is available in four specifications, lens size is available (Ø1.5mm-Ø20mm), heat dissipation mode can be optional air cooling heat dissipation or natural cooling, users can choose according to the requirements of use.

When choosing a UV LED spot light source, you need to consider the following key factors:

1. Power and intensity
   The power and intensity of the UVLED point light source are its most important performance indicators. These two parameters directly affect the efficiency and quality of the UV curing process. Spot UV curing device are available in high power & ultra high power, such as cool cure 365HP & cool cure 405. The image above illustrates the high power light intensity at different lenses.

2. Wavelength of the material
   The wavelength of the UV LED point light source should be selected according to the specific application. Different materials have different absorption rates for different UV output. Generally speaking, 365nm, 385nm, 395nm, and 405nm are the most common UVLED wavelength.
3. Size and Shape of the light head
   The size here refers to the diameter size of the spot & the length of the irradiation head; the shape refers to the shape of the irradiation head, and the shapes of the irradiation head are as follows: standard UV LED spotlight head, air-cooled UV LED cure head, 90° right-angle UV LED spot curing head, and side irradiation UV LED spot cure sources head.
4. Heat dissipation
   Since UVLEDs generate a lot of heat during operation, the heat dissipation performance should be considered when purchasing spot UV curing system to ensure stable operation and prolong service life.
5. Control interface & dimensions
   UVLED spot light source control interface should be simple and easy to use so that users can easily adjust the UVLED power, irradiation time, and other parameters. This touchscreen controller above can adjust the light intensity, irradiation time (manual on/off & automatic time off), and operation mode. In addition, the curing light source can be connected to PLC, MODBUS TCP, MODBUS 485, and of course, foot pedal control.
6. Brand and price
   Brand and price are also important factors in choosing a UVLED point light source. Products from well-known brands usually have better quality and longer warranty. At the same time, the price should be in line with the budget.

In summary, when choosing a UVLED point light source, you need to consider factors such as power, intensity, wavelength, size, shape, heat dissipation performance, control interface, as well as brand and price to ensure that you buy the right product for your needs.
