Description

Technical Field

[0001] The utility model relates to the technical field of UVLED ultraviolet curing lamp equipment, and specifically relates to a high-power water-cooled UVLED ultraviolet curing lamp. Background Art

[0002] In the field of ink curing of screen printing machines, high-power UVLED lamps are required for complete curing of inks. Traditional UV curing equipment mainly uses mercury lamps, which have low effective power, short lifespan, and adverse environmental impacts. Currently, LED ultraviolet curing equipment is being promoted, but the photoelectric conversion efficiency of LED equipment is not high, still generating a large amount of heat. At the same time, LEDs are very sensitive to temperature, and high temperatures will greatly shorten the lifespan of LEDs. Increasing the heat dissipation area and volume is an effective way to improve heat dissipation efficiency, but it conflicts with the requirement of a small size for the lamp head.

[0003] This paper presents a high-power water-cooled UVLED ultraviolet curing lamp, which adopts a highly efficient water-cooled radiator, has a small device size, good heat dissipation performance, and excellent waterproof performance, and is very suitable for use in fields such as ink curing.
