Surface-emitting channel for advertisement {LUMINESCENCE CHANNEL OF PLANE TYPE FOR ADVERTISING}

The present invention relates to a surface-emitting channel for advertisements, and more particularly, to partially block light emitted to the surface or to create a sense of excitement through a printed pattern, and to minimize the number of LEDs constituting the light emitting unit, while light is transmitted before and after ㆍIt relates to a surface-emitting channel for advertisements that allows the diffusion to be evenly distributed in all directions from the left and right, while improving the coupling structure of the first emission unit (cover) to the second emission unit (base) to facilitate attachment and detachment.

In general, lighting (lighting) is a generic term for a technology that makes the visual environment pleasant by using various types of light sources, and among them, the recently spotlighted LED lighting (Light Emitting Diode Lighting; 發光-照明) uses electricity to emit light with electricity. As lighting using a light emitting diode (LED) device that emits light, it is possible to create light of various colors ranging from red, green, blue to white, which are the basic elements of color by using the light emitting principle of LED.

The LED can be used for general lighting due to the development of white, and it is known as an eco-friendly lighting because it can significantly reduce energy than conventional lighting fixtures, has a longer lifespan, and does not use harmful substances such as mercury at all like fluorescent lamps.

Recently, such LED lighting is used as a light emitting channel for advertisements because of its excellent visibility as well as the lighting itself. The light emitting channel for advertisements as described above is for promoting a company name or product name through flat or three-dimensional characters or patterns.

The advertisements using the LEDs are arranged inside a three-dimensional metal or synthetic resin channel of various patterns or letters rather than irradiating the LED light from the back of a sheet printed on a flat surface. It is made so that the light can be transmitted and clearly recognized.

For the above reasons, the technology for a three-dimensional multi-faceted light emitting channel for advertisements using LEDs has recently been in the spotlight, and accordingly, research and development related to the field are being actively conducted.

For example, in Korean Patent Publication No. 10-1626724,'Three-dimensional LED sign lighting means (hereinafter referred to as Document 1)', the rear light-emitting part 11 is formed relatively thinner and wider than the front light-emitting part 14. And, a split ring 13 made of metal or synthetic resin having excellent thermal conductivity is further installed between the rear light-emitting part 11 and the front light-emitting part 14, so that a part of the rear light-emitting part 11 with a thin thickness is It protrudes from the edge of the light-emitting part 14 so that it can be expressed more clearly and three-dimensionally, and the LED substrate 12 is formed to form a ring shape in the shape of a character or figure displayed on a signboard on the rear light-emitting part 11. Supported by the support jaw (11d), and by installing the edge of the LED substrate in contact with the inner circumferential surface of the split ring 13, the heat of the LED substrate can be released through the split ring to increase the heat dissipation effect, and the A light diffusing layer 14c made of a translucent film is further installed on the front of the front light-emitting part to allow the entire front light-emitting part to output light evenly, and the front of the sign body 20 is made of a material capable of reflecting light. It is possible to reflect the light of the rear light emitting part, and by bending the end corresponding to the front light emitting part 14 of the split ring 13 inward to widen the contact area with the rear wall of the front light emitting part so that the front light emitting part is firmly coupled. , The lower inner surface of the side wall is in close contact with the outer surface of the support jaw formed in the rear light-emitting portion, so that the rear light-emitting portion is firmly coupled. A three-dimensional LED signboard lighting means, characterized in that spaces are formed on the front and rear surfaces of ), enhance the heat dissipation effect.

In addition, as another example, in Korean Patent Laid-Open Publication No. 10-2018-0103774'illumination signboard (hereinafter referred to as Document 2)', in a lighting signboard illuminated by light emitted from a light-emitting source, the light-emitting source is disposed, and the light is A support plate that penetrates; And a body illuminated by the light, wherein a substrate on which a light source is installed between the light source and the support plate is further provided, the support plate includes a receiving portion on which the substrate is seated, and at least one side of the body At least one of a translucent coating layer and a light diffusion coating layer is provided, and the body has a first body unit having a first coating layer of a first color, and a second coating layer coupled to one surface of the first body unit and having a second color. It proposes a lighting signboard including a second body unit having a.

Documents 1 and 2 as described above describe that light emitted from the LED substrate or the light emitting source (hereinafter referred to as the LED) is diffused in all directions to the light emitting unit or body (hereinafter referred to as the light emitting channel), so that there is a part capable of overall light emission, but the LED There is a limited problem in diversifying light emission.

In addition, in the prior art including Documents 1 and 2, when diversifying light emission by partially blocking the luminous channel for aesthetic expression, paint is applied to the luminous channel, that is, paint is applied, but in this case, it is painted in various shapes. There is a problem that is difficult to do and a problem in which the painting part is uneven (flatness problem).

In addition, in the case of paint coating as described above, there are problems that are harmful to the human body and environmental pollution due to the paint dust.

In addition, Documents 1 and 2 have a problem in that the structure or operation of fixing to the installation site and the joint fixing structure or operation between the separated light emitting channels are very complicated and cumbersome.
