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 term "on" or "under" includes both The meaning of the elements in contact with each other (directly) and the arrangement and formation of one or more other components (indirectly) between two components. Also, when an element is described as being formed "on" or "under" another element, the description can include meanings that the other element is formed in an upward direction of the element and the other element is formed in a downward direction from the element.

[0101] Furthermore, as used herein, relational terms such as "first", "second", "upper / upper / upper" and "lower / lower / lower" may be used to refer to only one entity or element Distinction from another entity or element w...

Abstract

According to one embodiment, a curing device is disclosed, comprising: a platform; a light-emitting module including a substrate and a plurality of light-emitting elements, the substrate is arranged on the platform, and the plurality of light-emitting elements are arranged on the substrate; a plurality of transparent blocks , disposed between the light-emitting module and the platform, wherein the substrate includes a plurality of first parts and a plurality of second parts, the plurality of first parts and the plurality of second parts are arranged along the first direction, and are arranged between the light-emitting elements in the first part The interval in the first direction is smaller than the interval in the first direction between the light emitting elements disposed in the second portion, and a plurality of transparent blocks are disposed on the first portion.

Description

technical field [0001] The present application relates to an ultraviolet curing device. Background technique [0002] Generally, an apparatus for curing or adhering a curing target by irradiating the curing target with ultraviolet light is called an ultraviolet curing apparatus. In this case, the curing target may be a UV-curable coating, 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] Ultraviolet light emitting diodes (LEDs) can be used as light sources for UV curing devices. 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. SUMMARY OF THE INVENTION [0006] Embodiments relate to providing UV curing devices with improved irradiance uniformity. ...
