Description

New process of producing light-emitting epoxy sign-board that the light source is from L.E.D}

In general, a signboard is generally called a signboard, and is a sign installed to inform a consumer of a business place or business such as a company or a store, and there are various kinds according to the installation place, internal structure, and advertisement type. Signboards are also diversifying as business environments become more complex and competition is fierce.

Accordingly, the signboard must be provided with differentiated identification or visibility so that consumers can easily recognize the contents, and lighting devices to be visible to consumers at daytime as well as at night are becoming essential elements.

The types of signage are largely classified according to the installation place and structure, and according to the installation place, the classification is classified into rooftop sign, wall signage, protrusion signage, headboard signage, and signage signage. It is classified into signboard, picture signboard, and plastic signboard.

Representative internal lighting devices for signboards that have been used so far are fluorescent lamps, neon lamps and L.E.D. Lamps.

In addition, these signs can be generally classified into a signboard called a Flex signboard and a channel signboard if they are largely classified based on their shape.

The Flexx signage is a signage that includes a light emitting device inside a frame formed in a retractable form in the most general form that can be commonly seen in the surroundings. to be. The Flexx signage includes a light emitting device that emits light by electric energy inside the sign in order to make the sign stand out at night. The most commonly used light emitting device is a fluorescent lamp.

The fluorescent lamps are installed in a number of signs, and other accessories such as ballasts for driving the fluorescent lamps are also installed.

Therefore, as the size of the sign increases, the number of fluorescent lamps used greatly increases, and thus the power consumption increases, and the trouble of replacing the end-of-life fluorescent lamps frequently and the cost of replacing them include environmental pollutants. There is a problem that a lot of waste fluorescent light is generated.

The signboard is composed of letters or figures in their respective three-dimensional shapes, and the installation of the wall surface is such that each three-dimensional shape is bonded by an adhesive or a coupling means, or the coupling frame is fixed to the wall surface to be installed, and each of the coupling frames joined to the wall surface. Combine the three-dimensional shape of.

The above channel board has many advantages such as having a luxurious image without damaging the aesthetics of the building, but because it does not self-illuminate at night, it is generally illuminated at night or indirectly from the back of the panel board. It allows you to see the Jannel signboard with the naked eye.

Therefore, there is a problem that the ability to discriminate at night, and the appearance of the building worsens due to the installation of lighting devices.

Neon signs vary in color depending on the gas enclosed in the neon tube, mercury gas is cyan, argon is purple, helium is rose, nitrogen is yellow, oxygen is orange, or two or more are mixed with gas or colored in glass. Various colors can be obtained.

Such neon signs have a significant effect as a dynamic advertising means at night, but the power consumption is large, wastes a lot of electrical energy, there is a problem that emits environmental pollutants at the time of disposal because it contains environmentally harmful gas.

In addition, the weight of the neon transformer is considerable, there is also a problem falling from the place where the neon signboard is installed, and there are frequent problems caused by this.

In order to overcome the problems of the conventional signage as described above, there are many designs and inventions using a new light emitting device, L.E.D.

Recently, the channel-type signboard is made of L.E.D. light emitting material and is classified into a cap channel type and a surface light emitting resin product, and has been greatly utilized.

The cap channel type is generally used widely in the manufacturing process and application of large sign of 1m or more, but in the small channel type signage which is much superior in its beauty and difficult to manufacture in the cap channel, the "surface light-emitting resin product" has been spotlighted. In addition, as the promotion of urban signage maintenance business, small channel type signage has been greatly utilized.

So far, the manufacturing process of the surface-emitting resin light-emitting sign using the LED as shown in Figure 6-① ~ ⑤;

① Production of three-dimensional letter frame made of stainless steel or galva (zanel)

② White paint inside the letter frame

③ PCB arrangement and attachment

④ Transparent synthetic resin (epoxy) molding

⑤ Synthetic resin molding diluted with color pigment

It has been produced through the process of. (M-light Patent No. 10-0694867)

However, in the production of letter frame (zanel), it was made of stainless steel or galva and aluminum was weak so that it could not make a channel of surface emitting resin sign.

In addition, by filling resin in the module part of LED at a very thick level (20-30m), it does not dissipate heat generated from LED, which shortens the life of the LED, and the transparent resin is discolored, resulting in low transparency and low illumination. In case of a defect that LED is not partly turned on, the problem that needs to be completely newly manufactured from the channel is raised in the state that it is impossible to calibrate or repair. Therefore, improvement measures are urgently required in terms of its utilization.

In addition, due to the heavy use of resin molding, the weight is too heavy, so it is required to improve the construction problems and measures for the installation of the sign. As mentioned above, the surface light-emitting resin channel is impossible with light and inexpensive aluminum material and expensive. There is a problem that you can only use the instan or galba.

On the other hand, as shown in the manufacturing process of the surface-emitting resin product, since the process must be made sequentially, the required production period to produce the product takes at least 6 days.

Therefore, the present invention reduces the manufacturing cost by replacing the material of the sine channel with light and inexpensive 'aluminum' instead of 'sten' or 'galva', and greatly shortens the process completion time since the module attachment and the resin filling process can be separated. It enhances the beauty of surface emitting products as it is and fundamentally solves various problems caused by heat generated from LED.

By dramatically reducing the amount of resin used, eco-friendly and weight-related construction problems are solved.

It is possible to correct a problem that a conventional product partially occurs or to make it impossible to replace or repair partially.

1) When the resin is coated on the LED, the heat dissipation is not possible, which shortens the lifetime of the LED and decreases the transparency.

2) aluminum is weak and cannot be used for channel production,

3) Signage construction problems due to the use of heavy resin molding and sequential production periods in the manufacturing process.

4) Problems that cannot be corrected or repaired if a defect occurs in which the LED is not partly lit.

5) The problem of stably depositing paint on aluminum

In the case of 1): It secured a space to fundamentally dissipate heat generated from LED, which prolonged LED life and prevented discoloration of transparent resin caused by heat.

Case 2): In the process of extruding the 'aluminum' plate, two lines of convex jaws were molded to increase the flexural strength.

In case of 3): It is used to replace the light 'aluminum' in the channel production, and it greatly solves the construction problem caused by the weight by drastically reducing the use of resin, and it is possible to separate the module and resin filling process. Greatly reduced.

Case 4) Partial replacement is possible when some of the attached LEDs are defective.

Case 5): The adhesive was stabilized by applying the lacquer coating after extrusion molding, unlike the conventional method, in order to increase the reflected light effect of the LED.

Urethane paint was applied and coated on the outer wall of the channel to increase the tensile strength and stably adhere the paint to aluminum.

With this invention, LED attachment and resin molding are separated to reduce work efficiency and process time. By selecting aluminum material, cost is reduced and resin usage is drastically reduced, and manufacturing cost is reduced to reduce product price and environmentally friendly. By being able to pursue the elements together, the existing high-priced resin products can be made more popular and solved the construction problems caused by weight.

This invention, which enables partial repair or replacement, saves time and money, and dramatically reduces the defect occurrence rate by setting the space of the light emitting portion and the display surface.
