Problems solved by technology

The ink accumulated on the surface of the fan will cause the fan to fail to rotate, which will cause the air cooling mechanism to fail, and eventually the lamp head will be overheated and damaged
The ink accumulated on the surface of the heat sink will reduce the heat dissipation efficiency of the heat sink, and will also cause the temperature of the lamp head to rise, which will affect the reliability of the lamp head

Abstract

The invention discloses an UV-LED light source. The UV-LED light source comprises a shell body, a COB module, a top cover module, a plurality of fans, a filter module and an air channel module, wherein the shell body comprises a pair of first side plates, a second side plate and a bottom plate, air outlet holes are formed in the first side plates, and an accommodating cavity is formed in the shellbody; the filter module is arranged between the fans and the bottom plate, and used for filtering air entering from the bottom plate; and the air channel module is arranged between the fans and the COB module, and guides out air which is guided in by the fans and forms a pair of air curtains which extend along the surfaces of the first side plates. The UV-LED light source has the following beneficial effects: ink and dust which are sucked in by the UV-LED light source and diffuse in air during air inlet can be reduced, so that the lives of the fans are prolonged; and air flow in the air channel uniformly passes through heat dissipation fins, so that the heat dissipation efficiency is increased. After air enters the air channel module, due to the blocking of L-shaped baffles at the two sides of each fan, air is uniformly distributed into the fins, so that the uniformity of heat dissipation is ensured, and the heat dissipation efficiency is increased.

Description

technical field [0001] The invention relates to the field of spray painting, in particular to a UV-LED light source. Background technique [0002] In recent years, the UV-LED market and applications have shown a trend of rapid development. Compared with mercury lamps, UV-LED has the advantages of lower energy consumption, longer life and non-toxic environmental protection. With the help of Minamata Convention and preferential policies such as power saving, UV-LED's replacement of mercury lamps continues to increase, and its applications are becoming more and more diverse. change. At present, the photocuring market accounts for 80% of the market share of UV-LED applications, including inkjet printing, printing, exposure, coating and other application fields. [0003] UV lamps for printing urgently need air-cooled UV-LED light sources with compact structure and high integration. However, the promotion of air-cooled UV-LED light sources on the market in this application fiel...
