The POP character pattern 141 of the POP cover 140 is formed of a transparent or translucent material so that light emitted from the LED module 120 inside can be transmitted and the light blocking pattern 142 is formed on the inner LED module 120 may be made of an opaque material so that light can not be transmitted.

For example, but not by way of limitation, the POP cover 140 may be made of a transparent or translucent material such as acrylonitrile-butadiene-styrene (ABS), acrylonitrile-styrene (AS), chloroprene- Ethylene-Vinylacetate copolymer (EVA), Fiber-Reinforced-Plastice (FRP), Grass-Fiber-Reinforced-Plastice (GRP), Melamine-Formaldehyde ), PA (Polyamide), PBT (Polybutylene-Terephthalate), PC (Polycarbonate), PE (Polyathylene), HDPE (High Density PE), LDPE (Low Density PE), PET (Polyathylene terephthalate) , POM (Polyoxyethylene), PP (Polypropylene), PPE (Polyphenylene Ether), PPO (Polyphenylene Oxide), PPS (Polyphenylene Sulfide), PS (Polystyrene), HIPS (Highimpact PS) ) May be formed.

A region in which the light blocking pattern 142 (formed of, for example, black ink) is not present in the POP cover 140 can be defined as the POP character pattern 141. [

In addition, the support board 110 may be further provided with a POP cover or a POP sheet which does not have an ordinary LED as well as a POP cover 140 having LEDs.

As described above, the embodiment of the present invention can provide a POP device 100 using LEDs which can contribute to sales promotion by concentrating the attention of consumers by displaying colorful and clear images of POP using the LEDs .

2A and 2B are an exploded perspective view and a cross-sectional view illustrating a POP device 100 using LEDs according to an embodiment of the present invention.

2A and 2B, a POP device 100 using an LED according to an exemplary embodiment of the present invention includes a support board 110, an LED module 120, a light diffusion plate 130, a POP cover 140 ). In addition, the POP device 100 may further include a heat sink 150 and a thermally conductive adhesive 160.

The support board 110 may be formed of various materials as described above, and has a substantially flat plate shape.

The LED module 120 is attached on the support board 110, which may be a plurality of LED (Light Emitting Diode) elements 121 on the upper surface.

The light diffusion plate 130 may be installed on the LED module 120 and may include at least one light shield plate 131.

The POP cover 140 may cover the LED module 120 and the light diffusion plate 130 and may include a POP character pattern 141 and a light blocking pattern 142 formed on the upper surface. That is, the POP cover 140 completely covers the upper surface and side surfaces of the light diffusing plate 130, and completely covers the side surfaces of the LED module 120.

At least one light shielding plate 131 is formed in the thickness direction of the light diffusion plate 130 so that the first light diffusion region 130a and the second light diffusion region 130a are formed on the light diffusion plate 130, The light diffusion region 130b can be divided. 2A and 2B, the light blocking plate 131 may include a first light blocking region 131a, a second light blocking region 131b, and a third light blocking region 131c. have. The light-shielding plate 131 may be formed in the form of a barrier from the upper surface to the lower surface of the light diffusion plate 130. The light shield plate 131 protrudes and extends from the lower surface of the light diffuser plate 130 to the upper surface of the LED module 120 so that the LED elements 121 of the LED module 120 pass through the light shield plate 131 It can not transmit light to other neighboring areas.

The light shielding plate 131 may be formed of, for example, but not limited to, a metal such as copper, aluminum, nickel, or an opaque plastic material. The light blocking plate 131 serves to prevent light from the first light diffusion region 130a from diffusing into the adjacent second light diffusion region 130b, for example.

The area of the LED module 120 and the POP cover 140 can also be distinguished by the configuration of the light shield plate 131.

Thus, the LED elements 121 are arrayed in the first LED region 120a, the second LED region 120b, the third LED module 120, and the fourth LED module 120, respectively.

Therefore, the luminous color of the LED element 121 arrayed in the first LED area 120a, the luminous color of the LED element 121 arrayed in the second LED area 120b, and the LED element arrayed in the third LED area 120c 121 and the LED element 121 arrayed in the fourth LED region 120d may be the same or different from each other and accordingly the color of the POP character pattern 141 in the first POP region 140a The color of the POP character pattern 141 in the second POP area 140b, the color of the POP character pattern 141 in the third POP area 140b, the color of the POP character pattern 141 in the second POP area 140b, May be the same or completely different from one another.

Therefore, the embodiment of the present invention not only brightens and sharpens the POP important phrases using LEDs, but also makes the luminescent colors the same or different for every POP phrase, and makes the luminescent time the same or different for each POP phrase, It is possible to provide a POP device 100 using an LED that can concentrate attention and contribute to sales promotion.

The heat sink 150 includes a first area 151 coupled to the opening 111 provided in the support board 110 and a second area 151 protruding rearward from the support board 110 through the opening 111 152). Such a heat sink 150 may be formed of, for example, aluminum, copper, SUS or the like, although not limited thereto. Furthermore, since the width (or the height) of the second region 152 is greater than the width (or height) of the first region 151, the heat sink 150 and the LED module 120 are bonded to the heat conductive adhesive 160 The heat sink 150 and the LED module 120 (including the light diffusion plate 130 and the POP cover 140) are not separated from each other after the support board 110 is mutually bonded.

The thermally conductive adhesive 160 is interposed between the heat sink 150 and the LED module 120 as described above and mechanically / thermally adheres them to each other.

In addition, the graphene heat dissipation coating material, which is an oxidative chemical separation method that separates the graphene film and the oxide film, is easy to coat by a spray method. Existing heat-radiating coating materials can not be used for devices that generate high heat due to organic or inorganic / inorganic composite heat-resistant coating materials of 95% or more. However, super heat conductive coating materials can be used at ambient temperatures up to 2,000 ℃.

[ So that deterioration of the LED module 120 can be prevented. Of course, the POP device 100 can be stably fixed to the support board 110 by the heat sink 150 having the stepped structure of the first and second regions 151 and 152.

Furthermore, the POP device 100 using the LED according to the embodiment of the present invention may include the main material of the thermally conductive adhesive 160 in the optical diffusion plate 130 and / or the POP cover 140.
