Description

TECHNICAL FIELD [0001] The present invention relates to a unit light irradiating module and an expanding light irradiating device using the unit light irradiating module.

The present invention relates to a unit light irradiating module and an expanding light irradiating device using the unit light irradiating module. More particularly, the present invention relates to a unit light irradiating module comprising a base and a light source unit, And an expandable light irradiation apparatus using the unit light illumination module.

Generally, ultraviolet ray paints are increasingly used due to environmental friendliness, economical efficiency, workability and productivity improvement and energy saving effects.

An ultraviolet ray paint is a material which is characterized by ultraviolet (UV) curable material and refers to a material which undergoes a photochemical reaction by the energy of ultraviolet rays (100 to 400 nm) and cures from a liquid phase to a solid phase.

Here, the ultraviolet ray paint has characteristics that the reaction time and physical properties of the coating film are changed depending on the relationship with the ultraviolet ray curing machine. Such ultraviolet ray paint and ultraviolet ray curing machine are used not only for the manufacture of large furniture and flooring, And is widely used in various industrial fields.

On the other hand, conventional ultraviolet curing apparatuses generally use lamps, and users using such lamp-type ultraviolet curing apparatuses suffer from a number of problems such as thermal deformation, deterioration in productivity, deterioration in quality, and deterioration in adhesive strength.

Specifically, when optical coating is performed with thin PET or PVC film, thermal deformation may occur. This is because when an ultraviolet lamp (UV lamp) is turned on, not only ultraviolet (UV) .

Since the internal temperature of the ultraviolet lamp is high, the heat from the lamp is very strong and the heat transfer is conducted, convection, and radiant heat, which causes the temperature of the product itself to rise sharply. The degree to which the temperature of the product rises depends on the number of lamp kW, the quantity of lamp, the speed of conveyor, the material of the product, etc. However, since the internal temperature of the lamp is considerably high, the product passing under the lamp indirectly receives heat. It is inevitable that there will be a defect in the form of a branch.

In order to solve the above problems, a technology relating to a curing device using LEDs other than a lamp is disclosed in Korean Patent No. 10-1351716 ("UV curing device using LED"), , The size of the curing device 11 is limited depending on the size of the product 10 and there is a limit in terms of price and system specifications and the size and light quantity are applied to various kinds of products in accordance with requirements It is inefficient in terms of productivity.
