Description

LIGHT EMITTING DEVICE USING L.E.D}

The present invention relates to a light emitting advertisement device using an LED, and particularly, to obtain a uniform light emitting effect by emitting an epoxy in an advertisement display form using the LED.

In general, indoor or outdoor advertisements or signs, neon signs using neon gas or signs for lighting LEDs by lighting LEDs are known to be easily recognized at night.

First, the signboard using neon sign has the advantage of easy visual recognition because of its high brightness, but it is easy to be damaged because the neon tube is exposed, it is difficult to clean water, and it uses high voltage and consumes a lot of power and generates high temperature heat. There is an inefficient disadvantage.

In addition, the signboard that illuminates the floodlight by placing the LED inside the floodlight has the advantages of low price, low power consumption, and free placement of the LED, but only the portion where the LED is disposed is exceptionally bright and the edge is dark. There is a problem that the entire signage is not uniformly illuminated.

The present invention has been made to solve the above problems, the object of the present invention is to obtain a uniform light emitting effect by emitting the epoxy of the advertising display form using the LED.

And a switch installed on a rear surface of the panel to turn on / off the control unit.

Hereinafter will be described a preferred embodiment according to the present invention.

First, the configuration of this embodiment will be described.

As shown in the figure, the light emitting advertisement device according to the present embodiment includes a case 10 in which a groove 12 is formed in the form of advertisement letters, and a first reflective material is coated on the groove 12, and the bottom surface of the groove 12. PCB 20 coupled to the second reflective material and coated on the surface, a plurality of first LEDs 30 connected at uniform intervals so that light is radiated on the PCB 20 in an external horizontal direction, and PCB 20 In the groove 12 to cover the plurality of second LEDs 40, the PCB 20, the first LED 30 and the second LED 40 are connected at a uniform interval so that light is irradiated downward from the Filled and solidified flame-retardant epoxy resin 50, the top surface of the flame-retardant epoxy resin 50, the color epoxy resin 60 containing a color pigment, and the panel 70 coupled to the back of the case 10 and And a control unit 80 provided between the case 10 and the panel 70 to control the lighting of the first LED 30 and the second LED 40, and the panel 7. It is provided on the back of 0) is made of a switch 90 for turning on / off the control unit 80.

The case 10 may be manufactured by molding or by processing wood.

And since the flame-retardant epoxy resin 50 is in direct contact with the first LED 30 and the second LED 40, it is manufactured by adding a flame-retardant material in order to prevent burning by high heat.

In addition, since the color of the overall character is determined by the color of the color epoxy resin 60, the user selects and applies the color epoxy resin 60 of the desired color.

On the other hand, the controller 80 allows power to be input from the outside.

Hereinafter, a process of manufacturing the light emitting advertisement device of the present embodiment will be described.

First, the grooves 12 are formed in the case 10 in the form of advertisement letters, and the first reflective material is coated on both sides of the grooves 12.

Then, the first LED 30 is connected to the PC 20 having the second reflecting material coated on the surface at uniform intervals so that light is irradiated in the horizontal direction outside, and the second LED 40 is lowered on the PC 20. Connect at equal intervals so that light is irradiated.

Next, the PCB 20 to which the first LED 30 and the second LED 40 are connected is installed in the groove 12 of the case 10.

Then, the flame retardant epoxy resin 50 is filled in the groove 12 so as to cover the PC 20, the first LED 30, and the second LED 40, and then solidify.

When the flame retardant epoxy resin 50 is solidified in this way, the color epoxy resin 60 containing the color pigment is coated thereon and solidified.

And the back of the case 10 is provided with a control unit 80 for controlling the lighting of the first LED 20 and the second LED 40 is connected to the external power source. Then, the panel 70 is coupled to the defecation of the case 10 so that the controller 80 is protected, and a switch 90 for turning on / off the controller 80 is installed on the rear surface of the panel 70.

Hereinafter, the operation of the light emitting device having the above configuration will be described.

First, when power is supplied to the controller 80 and the switch 90 is turned on, the first LED 30 and the second LED 40 installed in the PC 20 are turned on to emit light.

Accordingly, the light emitted from the first LED 30 in the horizontal direction is reflected from the side wall of the groove 12 of the case 10 and irradiated upward, thereby illuminating the flame-retardant epoxy resin 50. The light emitted downward from the second LED 40 is reflected from the upper surface of the PC 20 and irradiated upward to illuminate the flame-retardant epoxy resin 50. As the light is incident from the side and the bottom of the flame-retardant epoxy resin 50, the light is scattered in the flame-retardant epoxy resin 50 to uniformly emit light.

Light passing through the flame-retardant epoxy resin 50 in the above will emit light in the corresponding color while passing through the color epoxy resin 60 of the surface. In this process, since the flame retardant epoxy resin 50 contains a flame retardant component, it is not burned by the high heat generated from the first LED 30 and the second LED 40.

In this way, the light emitting advertisement device of the present embodiment displays the advertisement uniformly in beautiful colors to the viewer.

On the other hand, when the switch 90 is turned off, the controller 80 turns off the first LED 30 and the second LED 40.

As described above, the present invention is coupled to the bottom surface of the case 10 and the groove 12, the first reflecting material is applied to the groove 12 formed in the form of advertising characters, the second reflective material is applied to the surface PCB 20, a plurality of first LEDs 30 connected at uniform intervals so that light is radiated outwardly on the PCB 20, and at uniform intervals so that light is irradiated downward on the PCB20. The flame-retardant epoxy resin 50, etc., filled and solidified in the groove 12 to cover the plurality of connected second LEDs 40, the PC 20, the first LED 30, and the second LED 40, etc. A light emitting advertisement device using an LED, the light emitted from the first LED 30 and the second LED 40 is reflected from the side wall of the groove 12 of the case 10 and the top surface of the PC 20 and scattered While illuminating the flame-retardant epoxy resin (50), light is scattered from the flame-retardant epoxy resin (50) to uniform light emission To the effect that the.

Although the present invention has been described as an embodiment, the present invention is not limited to the above-described embodiment, and the general knowledge in the field to which the present invention belongs without departing from the gist of the present invention claimed in the utility model registration claims. Anyone with a variety of variations will be possible.
