Description

Multi-Purpose Light Emitting Device {LIGHTING DEVICE}

The present invention is a multi-purpose light emitting device that has a bar shape and is used in the floor of a structure, an interior interior and a channel type signboard, and uses LED as its light source and extends its life by completely sealing it with a silicon finish. The present invention relates to a multi-purpose light emitting device having improved.

A signboard is generally referred to as a signboard. In order to attract the attention of various people in a store, company, or institution, a signboard, a front signboard as well as a signboard on the front of a store, written on the front of the store by using a name, a brand name, a business item, etc. Nowadays, advertising signs, rooftop signs, in-car advertising, signboards, advertising towers, neon signs, and power pole advertising are now very diverse.

Such a signboard can be generally classified into a signboard in the form of a letter called a flex signboard and a channel-type signboard if it is largely classified based on its form.

The FLEX signage is a signage that maximizes the advertising effect with a variety of graphics and pictures by including a light emitting device inside the frame formed in a retractable form in the most common form commonly seen in the surroundings and excellent light transmittance. A signboard is a signboard that attaches three-dimensional letters, patterns, etc. to the wall individually.

The lighting devices of the signboards that have been used up to now are mainly composed of fluorescent light signboards and neon signs that are lit when necessary by embedding fluorescent lights inside the acrylic signboard, and light emitting device signs and optical fiber signs are also used.

In the case of the fluorescent lamp lighting signboard, since the fluorescent lamp and the ballast are built in the interior, not only has a considerable thickness, but also the durability of the fluorescent lamp bulb has a problem that must be frequently replaced.

In addition, the neon sign can be expected to have a high quality lighting effect such as a soft lighting effect, but it is not possible to display a sophisticated figure, so it appears not only very coarse form on the small signboard of the short distance, but also because the installation cost and power consumption is excessive It is giving a lot of burden to.

In addition, the neon sign light emitting device injects a fluorescent gas such as neon, nitrogen, mercury gas into the transparent glass tube, and when a high voltage is applied to both ends thereof, the fluorescent gas becomes a discharge medium and has a desired color and shape. It will emit light. However, since the power consumption is large due to the high-pressure discharge, and a large ballast is used, the overall weight of the neon sign light emitting device is increased, making it difficult to install and having unstable problems.

In addition, the gas may cause environmental pollution, it is difficult to maintain the airtightness of the neon sign installed in the outdoors, there is a problem that frequent electrical failure accidents occur in the rain.

On the other hand, the conventional channel-shaped signboard has a three-dimensional shape of each letter or figure, the installation of the wall surface, each of the three-dimensional shape is bonded to the adhesive or coupling means, or fixed to the wall to be installed to the coupling frame coupled to the wall surface Join each solid shape to the frame.

The above channel type signboard has many advantages such as having a luxurious image without damaging the aesthetics of the building, but since it does not self-illuminate at night, it is generally illuminated directly at night or indirectly from the back of the channel type signboard. It is possible to see the glass signboard with the naked eye.

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

In order to overcome the problems of the conventional signboards as described above, there are many designs and inventions using LEDs, which are new light emitting devices, but due to the structural characteristics of the LEDs, it is difficult and time consuming to produce a signboard using the LEDs. In particular, there is a problem that the manufacturing price of the signboard is increased when a large amount of LEDs are installed.

In addition, since the lighting device is disposed outside due to the nature of the outdoor signage, there is a problem in that water leakage occurs frequently according to the climate, such as high humidity or rain, thereby shortening the lifespan of the lighting device.

Therefore, the present invention can be easily installed even in a narrow space because it is manufactured as a miniaturized finished product, and light emission which can improve the advertisement effect of the signboard using a light source having low power consumption and high luminance and excellent visibility than the conventional one. In providing a device.

In addition, it is another object of the present invention to provide a light emitting device that dissipates heat generated from a light source to protect internal electronic devices and signs from heat, and prevents leakage to extend the life of the product to improve the reliability of the product.

The present invention for achieving the above object is made of an aluminum material and the outer surface is formed with an uneven portion, the main body portion having an open side of the opposite sides and the upper tubular shape; Each fitting jaw is protruded so as to be respectively disposed on both sides at intervals corresponding to the intervals of both sides of the main body portion, and a portion is received and fitted into the main body portion, and the length of the main body portion is formed in the both fitting jaws. Cover extending through the wire, the cover and the fitting portion is integrally formed using a mold method; A substrate having a plurality of inflow grooves disposed in an open upper portion of the main body and having a light source including a plurality of LEDs, and having a plurality of inflow grooves recessed inward along a longitudinal direction thereof so that the following finishing material may flow into the main body; And a light emitting unit having a connection pin for electrically connecting the wires. And a finishing material applied to the upper part of the light emitting part with a silicon material to seal the main body part, the cover part, and the light emitting part.

As described above, the light emitting device according to the present invention applies a body portion having an uneven portion made of aluminum to dissipate heat generated from a light source, thereby protecting electronic signs inside the body portion as well as signboards from heat, and finishing the exterior of the body portion. It is applied with the airtight sealer, which prevents the leakage of water from the outdoor signboard, thus improving the life of the product and improving its reliability.

In addition, by applying SM LED as a light source of the light emitting device, the power consumption can be significantly lowered compared to a light emitting device such as a fluorescent lamp type or a neon sign type which has a high power consumption, and the light emitting device can be miniaturized. Since it can be easily placed inside the signboard, there is an economic effect such as reducing the production cost and operating cost of the signboard.

In addition, due to the silicon finish, the light emitted from the high-brightness light source can be evenly distributed, thereby ensuring the visibility of the signboard and maximizing the advertising effect and other terrier effects of the signboard. It is not only simple but also easy to manufacture the light emitting device.
