Embodiment Construction

[0012] Hereinafter, examples of embodiments of a light irradiation device, a photocuring device, and a printing device of the present disclosure will be described with reference to the drawings. In addition, the following content is an illustration of embodiment of this indication, and this indication is not limited to these embodiment.

[0013] figure 1 An example of an embodiment of the light irradiation device of the present disclosure is schematically shown. figure 1 (a) is a side view, (b) is a bottom view.

[0014] The light irradiation device 1 is a device for curing a photocurable material by irradiating light (for example, ultraviolet rays). The light irradiation device 1 is mounted as a photocuring device on a printing device such as an offset printing device or an inkjet printing device. Thus, after the printing device adheres the photocurable material (for example, photocurable ink (ultraviolet curable ink), etc.) Print on the printed medium.

Abstract

A light-irradiating device (1) according to the present disclosure is provided with: a light-emitting element (4); a housing (9) in which the light-emitting element is disposed and which has, in a light-irradiating surface (9a), an irradiating opening (10) allowing for passage of light of the light-emitting element; a gas-supplying flow path (21) arranged with an end thereof positioned near the irradiating opening in the light-irradiating surface of the housing; and a gas-discharging opening (23) provided at the end of the flow path and having a plurality of first openings (23a) arranged correspondingly along a width direction of the irradiating opening, and a plurality of second openings (23b) arranged corresponding to both ends in the width direction of the irradiating opening. The light-irradiating device is capable of reducing deviation of the distribution of discharged gas and improving the reliability of a curing reaction.

Description

technical field [0001] The present disclosure relates to a light irradiation device that can be used for curing ultraviolet curable resins, inks, and the like, and a printing device equipped with the same. Background technique [0002] In a light irradiation device in which a light source and a drive substrate for driving the light source are housed in a housing, a lamp emitting ultraviolet rays or an LED (Light Emitting Diode: Light Emitting Diode), for example, may be used as a light source. The light irradiation device capable of irradiating ultraviolet rays includes applications in the printing field such as curing of photocurable materials (resins, inks, etc.), medical-related fields such as sterilization applications, and adhesives or ultraviolet-curable resins in the mounting of electronic components. It is widely used in the field of assembly manufacturing such as curing, and in the field of drying processing in which an object to be irradiated is efficiently dried b...
