Description

ULTRA VIOLET CURE APPARATUS USING LEDS

The present invention relates to an ultraviolet curing apparatus using an LED, and more particularly, to an ultraviolet curing apparatus using an LED, and more particularly, to an ultraviolet curing apparatus having an LED module for irradiating UV light on the protrusions and depressions on a housing having protrusions and depressions, .

The application fields of ultraviolet (UV) are unlimited in all industries and can be applied in various fields.

For example, by employing a UV paint, it is possible to reduce the generation of harmful gas generated during drying or curing, thereby protecting the operator's health and reducing environmental pollution. In addition, the ultraviolet cured product surface has a very strong hardness, and the drying and curing speed of the product can be instantly cured within 1 to 2 seconds, which can dramatically improve the productivity.

An ultraviolet ray curing apparatus using ultraviolet rays is mainly used by mounting a plurality of UV lamps of about 9 watts (W). The power consumption of the lamp is relatively high and the heat generation temperature is high, which causes thermal distortion in the object to be cured. In addition, due to the nature of the lamp, the emission wavelength is relatively wide, ranging from 200 to 400 nm, and ultraviolet rays of wavelengths not suitable for the resin material to be cured and the adhesive used can be applied.

In addition, since the curing time is longer than 3 minutes and the device such as a lamp and a lamp regulator must be additionally formed in the curing device itself, the weight is over 2Kg and it is heavy and it is inconvenient to use. It is necessary to replace the lamp every 3 to 4 months.

In order to solve such a problem of the UV lamp, a method of applying the LED as a UV light source has been suggested, and an example of an ultraviolet curing apparatus using the LED according to the prior art is shown.

An ultraviolet curing apparatus using LED according to the related art arranges a plurality of LEDs on a plane

By using the LED as a UV light source, it is possible to solve various problems caused by using a conventional UV lamp.

However, since the conventional ultraviolet curing apparatus using LEDs requires a plurality of LEDs to be arranged closely on a plane, arrangement and wiring are not easy, and there is a limit to the LED arrangement by using only a limited planar space.

Particularly, the most important part of the UV curing apparatus is to control the density of UV light, that is, the optical power. In the conventional UV curing apparatus using LEDs, the same LEDs are arranged to control the light density on the surface to be irradiated with UV It is not easy.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in an effort to solve the problems of the prior art as described above, and an object of the present invention is to solve the problem that arrangement and wiring are not easy by arranging a large number of LEDs on a plane in the case of an ultraviolet- By using only the planar space, the problem of low density due to the limitation of the LED array is solved.

Further, the conventional UV curing apparatuses using LEDs are all arranged in the same LED to solve the problem that it is not easy to control the density of UV light, that is, the optical power, which is the most important part in the UV curing apparatus.

According to an aspect of the present invention, there is provided an ultraviolet curing apparatus using an LED, comprising: a plurality of LED modules arranged to emit UV light; And a housing having a plurality of protrusions and a plurality of depressions alternately formed on an area corresponding to a bottom surface of the LED module, wherein the LED module is disposed on a protrusion and a depression of the housing, the height of the protrusion and the depression And a UV light source is formed in a stepped shape according to the difference.

The LED module of the first UV light source and the lens of the LED module of the second UV light source are formed to have different magnifications from each other, .

According to the present invention, it is possible to further increase the density of the LED through the three-dimensional LED arrangement of the stepped structure, and further, by implementing the UV light as the LED module, the maintenance of the ultraviolet ray curing device is advantageously facilitated.

In the present invention, the UV light source is divided into a first UV light source and a second UV light source according to a step structure, and the first UV light source and the second UV light source are controlled to emit different amounts of light, The UV light density can be easily controlled.
