[0043] FIG. 1 is a schematic configuration diagram of an ultraviolet irradiation device 100 according to a first embodiment of the present invention.

[0044] As shown in FIG. 1 , the ultraviolet irradiation device 100 is composed of four irradiation units 2 , four connection cables 22 , and a main body unit 1 .

[0045] Each irradiation unit 2 is connected to the main body unit 1 by a connection cable 22 , and each irradiation unit 2 can be freely attached to and detached from the main body unit 1 . Furthermore, the main body unit 1 supplies electric power to each irradiation unit 2 according to the user's setting. In addition, the main body unit 1 displays the irradiation status of each irradiation unit 2 and the like to the user.

[0046]The irradiation unit 2 drives the light source with the electric power received from the main body unit 1 to generate ultraviolet rays to irradiate the object. In addition, when the life of the light source of the irradiating unit 2 is ex...

Embodiment approach

[0136] In addition, according to the first embodiment of the present invention, based on the attenuation characteristic of the light emission amount with respect to the cumulative value of the irradiation energy of the UV light source, the judgment of whether the UV light source has reached the end of life, the calculation of the remaining life of the UV light source, and the calculation of the remaining life of the UV light source are performed. Judgment of the aging state. Also, the executable number of irradiation patterns is calculated by dividing the remaining lifetime of the UV light source by the irradiation energy of the irradiation pattern. Therefore, life management of the UV light source can be performed with high precision, and production management of a production line using the ultraviolet irradiation device can also be performed with high precision.

[0137] In addition, according to the first embodiment of the present invention, since the irradiation pattern sp...

Abstract

The present invention provides a UV irradiation apparatus having an index capable of performing life management at a high accuracy. A control part 4 receives a current value fed to each of irradiation parts 2 from a power source part 6 for a light source and integrates it in every predetermined control period. Further, the control part 4 multiplies the integrated current value by a voltage drop of a UV light source 16 to calculate an irradiation energy of the UV light source 16. Further, the control part 4 adds the calculated irradiation energy to an accumulation value of the irradiation energy read from a memory part 18 of the irradiation part 2 and updates the accumulation value of the irradiation energy stored in the memory part 18 by the value after the addition. Further, the control part 4 displays the calculated irradiation energy of the UV light source 16 and the accumulation value of the irradiation energy on a display part 8.

Description

technical field [0001] The present invention relates to an ultraviolet irradiation device for irradiating ultraviolet rays, and more particularly to an ultraviolet irradiation device having a light source composed of LEDs. Background technique [0002] In recent years, an ultraviolet curing method (Ultra Violet Curing; hereinafter referred to as UV curing method) has been widely used as a curing method for adhesives or coatings in many industrial fields. [0003] The UV curing method is a technique in which a UV curing material is irradiated with ultraviolet rays to cause a photopolymerization reaction, thereby turning a monomer (liquid) into a polymer (solid). Common UV curable materials include monomers, oligomers, photoinitiators and additives. Also, when ultraviolet rays are irradiated, the photoinitiator is excited, thereby converting monomers into polymers using the excitation energy. [0004] Therefore, compared with the thermal curing method using heat energy, the ...
