Problems solved by technology

[0002] Traditional UV inks are cured by UV Lamp (mercury lamp), but due to the large heat and strong radiation of UV Lamp (mercury lamp), ink discoloration and yellowing are prone to occur, the product has a high defect rate, and the curing effect cannot be achieved. It is very ideal, especially after the ink is cured, the surface dryness and glossiness are not good, which will greatly increase the production cost

Embodiment Construction

[0016] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0017] refer to figure 1 , 2 As shown, it is a schematic structural diagram of a preferred embodiment of the present invention. The present invention relates to a method for curing ink on the surface of an LED light source. The method includes the following steps:

[0018] The first curing step S1 uses UV LED lighting to separate the diaphragm 2 from the UV ink on it, and the UV ink adheres to the surface of the LED unit 1; select a UV LED with a suitable wavelength according to the color of the ink to obtain enough Power and lighting effects, realize the separation of the diaphragm 2 and the UV ink on the diaphragm 2, and meet the separation of the UV ink to adhere to the surface of the LED unit 1, so that the required pattern an...

Abstract

The present invention relates to the LED light source manufacturing field, in particular to an LED light source surface printing ink curing method. The method comprises a first curing step of adopting the UV LED illumination to separate a diaphragm and the UV printing ink on the diaphragm, wherein the UV printing ink is attached on the surface of an LED unit; a second curing step of adopting the UV LED illumination to irradiate the UV printing ink attached on the surface of the LED unit until the UV printing ink is cured thoroughly; a finishing step of taking out or transmitting the cured LED unit. The LED light source surface printing ink curing method of the present invention simulates a spectrum effect of a conventional mercury lamp effectively, weighs a plurality of factors of the illuminance, the total energy consumption and the total cost very well, realizes a printing ink curing method having the optimal cost performance, cures according to steps, cures the printing ink on the surface of the LED light source surface, also guarantees the curing quality, avoids the unfavorable conditions that the color of the printing ink changes, the printing ink yellows, etc., and enables the yield to be improved and the manufacturing cost to be reduced.

Description

technical field [0001] The invention relates to the field of LED light source production, in particular to the technical field of ink curing on the surface of the LED light source. Background technique [0002] Traditional UV inks are cured by UV Lamp (mercury lamp), but due to the large heat and strong radiation of UV Lamp (mercury lamp), ink discoloration and yellowing are prone to occur, the product has a high defect rate, and the curing effect cannot be achieved. It is very ideal, especially after the ink is cured, the surface dryness and gloss are not good, which leads to a great increase in production cost. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a method for curing ink on the surface of LED light sources, replace traditional mercury lamp curing, ensure curing quality, and reduce production costs. [0004] To achieve the above object, the present invention adopts the following techn...
