Embodiment Construction

[0099] Hereinafter, exemplary embodiments of the present invention capable of achieving the above objects will be described with reference to the accompanying drawings.

[0100] In the description of the embodiments, when an element is described as being formed "on" or "under" another element, the terms "on" or "under" include both. means that two elements are (directly) in contact with each other, and that one or more other elements are arranged and formed (indirectly) between two elements. Also, when an element is described as being formed "on" or "under" another element, the description may include the meaning that another element is formed in an upward direction of the element and another element is formed in a downward direction from the element.

[0101] In addition, as used herein, relative terms such as "first", "second", "upper / upper part / upper" and "lower / lower part / lower" may only be used to refer to one entity or element to be distinguished from another entity or ...

Abstract

According to an embodiment, disclosed is a curing-device comprising: a stage; a light emitting module including a substrate disposed on the stage and a plurality of light emitting elements disposed onthe substrate; and a plurality of transparent blocks disposed between the light emitting module and the stage, wherein the substrate includes a plurality of first sections and a plurality of second sections which are disposed in a first direction, the intervals in the first direction between the light emitting elements disposed in the first sections is smaller than the intervals in the first direction between the light emitting elements disposed in the second sections, and the plurality of transparent blocks are disposed on the first sections.

Description

technical field [0001] The present application relates to an ultraviolet curing device. Background technique [0002] Generally, a device that cures or adheres a curing target by irradiating the curing target with ultraviolet light is called an ultraviolet curing device. In this case, the curing target may be a UV-curable paint, adhesive, or opaque material. [0003] Mercury UV lamps, halogen lamps, etc. can be used as light sources for generating UV light for UV curing devices. The problem, however, is that these lamps are inefficient and expensive. [0004] UV Light Emitting Diodes (LEDs) can be used as light sources for UV curing units. UV LEDs have the advantages of high efficiency, relatively low cost, and long service life. [0005] However, since multiple UV LEDs are provided, irradiance uniformity is an important issue. Contents of the invention [0006] Embodiments are directed to providing UV curing devices with improved irradiance uniformity. [0007] Embo...
