Description

An illuminator diffused light using layer of infinitesimal air bubble}

The present invention relates to a diffuse reflection floodlight apparatus using a microbubble layer, and more particularly, in a floodlight apparatus that transmits light by using a lamp as a light source to have lighting and advertising effects, the inside of which is fine when the floodlight panel is manufactured. The present invention relates to a lighting device that maximizes visual effects by scattering without exposing a light source by allowing a bubble layer to be formed and scattering of light.

As it is well known, the signboard for advertisement attracts attention by neon signs, or it is equipped with a plurality of fluorescent lamps inside and covers the front with panaplex cloth or acrylic plate to transmit light so that the attached letters or patterns stand out. How to do it is mainstream.

However, in the case of neon signs, the cost is expensive and many neon tubes are used, and the weight is heavy and easily broken, and if some of the neon tubes are defective, the letters or patterns are damaged and cannot be recognized. In the case of a frame sign that covers the entire surface with a Panaplex or acrylic plate, a plurality of fluorescent lamps are built-in to allow light to pass through the front cover so that letters or patterns can be revealed. Because the light is transmitted through it, the lamp should be installed closely, and no matter how tightly installed, there will be a gap between the fluorescent lamp and the lamp, so that dark and bright spots are formed and become unsightly as the life of the lamp becomes longer. . In addition, when some lamps are defective, some dark areas are generated and become ugly, so the lamps must be replaced at any time. These are mostly large signs, and both of them consume a lot of power, so that both the advertiser and the country can It is the main cause of consumption.

In addition to the signboard material, lamps and lamp covers that are applied to various lighting fixtures, the light source is exposed as it is due to the straightness of the light, in this case there is a problem in the visual effect, so as to scatter the glass material In this case, the surface is formed by sand blasting or etching to form fine concavo-convex, so that the effect of refraction of light can be induced, and white pigment on transparent material such as acrylic or polycarbonate Or most other colors are used. However, such a light transmitting material has a disadvantage in that the effect of light from the light source is decreased by significantly reducing the transmittance of light, and in the case of glass, light is scattered from sand blasted or etched surfaces to expose the light source as it is. In the case of semi-transparent synthetic resin, the pigment put in the manufacturing process interferes with the light transmission, and the brightness of the transmissive surface is significantly lowered than the brightness of the original light. There was a limit to the realization of this beautiful light fixture.

The present invention has been made in view of the above-mentioned drawbacks, when producing a floodlight plate with a transparent resin composition such as polyurethane forcibly produced a myriad of fine bubble layer and then added to the manufacturing process to harden, the surface is smooth In the inside, it is formed of a myriad of fine bubble layers as a whole, and when it transmits light, it is repeated diffuse reflection and refraction to form a bright and clean eye-catching pastel pastel floodlight plate. Reflectors are installed at intervals on the back of the panel, and then the green, yellow and red high-brightness LEDs are installed on the lower side to reflect them, making beautiful signs and applying them to various luminaires. I was able to realize a lighting fixture, and it is light and is strong in a shock, It provides an ideal lighting device that can be installed at low cost and installed at low cost.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

Referring to the method for manufacturing a bubble transparent plate applied to the present invention, a method for forcibly forming a fine bubble layer on a transparent material in a gel state in the process of injecting into a plate or a mold suitable for various forms to solidify The present invention can be realized by the following preferred embodiments.

In the method of making a bubble-containing material of two-component urethane, urethane can generally control the curing time and hardness by adding polyol, acrylic or polycarbonate in the amount desired by the manufacturer. There is a method of forcibly injecting air with stirring to form bubbles, and curing these bubbles into a desired shape before exiting the liquid with high viscosity.

In another method, a small amount of water is added to the main liquid and the curing agent of the two liquids, and when it is stirred, bubbles are immediately generated, and when it is cured to a desired shape, a material having a bubble layer as described above can be obtained.

In the manufacturing method according to the present invention, even in the case of using a synthetic resin, in order to solve problems such as air rising up after injecting air or a blowing agent using an impeller, the physical method is rotated or changed randomly until it is cured. Mobilization is also possible. When using this method, it is possible to prevent the movement of air to one side when manufacturing a product having a low coefficient of friction between resin and air, so that there is no abnormality in producing a desired material.

There are a wide variety of materials that can be produced by the above manufacturing process. The higher the density, the higher the light transmittance. For example, in addition to the above-mentioned synthetic resin, that is, acrylic or polycarbonate, various thermoplastic resins such as PP (Poly propylene), PET (Poly ethylene telephtylate), and PS (Poly stylene) may be used. In the production of thermosetting resins such as secondary and secondary production and epoxy resins, such effects can be sufficiently obtained.

According to the above manufacturing process, a bubble layer is forcibly formed on the transparent resin to cause scattering, refraction, and diffuse reflection of light in the entire material rather than the surface layer of the material, thereby obtaining the effect of pastel tone as a whole. The bubble transparent plate 1 having a bubble layer is formed by covering the entire surface of the frame 2 in accordance with a letter or a light-transmitting part designed in various forms, and the reflecting mirror 3 is provided on the rear side at intervals on the inner side thereof. The high brightness LEDs 4 of green, yellow, and red are provided below the gaps, and the rear surface of the frame 2 is covered with the rear cover 5.

According to the present invention configured as described above, when the green, yellow, and red high brightness LEDs 4 emit light individually or in combination with a timer, various color changes are caused, and the emitted light is diffused through the reflector 3 installed on the rear surface. By reflecting and passing through the bubble transparent plate 1 on the front side, a beautiful lighting effect can be obtained. In this case, the bubble transparent plate 1 has a myriad of fine bubble layers throughout the interior rather than on one surface or one side in a manufacturing process. When the light is transmitted through light, repetitive diffuse reflections and refractions can be realized to realize beautiful floodlights in pastel tones that can catch the eyes in a bright, clean and unblinded state.

The bubble floodlight plate of the present invention as described above can maintain the pastel tone color as it is, there is an advantage that the exposure of the light source can be reduced as much as possible by adjusting the thickness in the manufacturing process.

When the present invention is applied to various lighting devices as well as signboards, it is of course possible to greatly contribute to energy saving. Current neon signs have a huge disadvantage in terms of power consumption, compared to the advantages of various colors of its own advantages, the present invention, by using a mixture of green, red, yellow LEDs, various near infinite It is possible to express colors, and it is possible to realize various color changes that are not comparable to neon signs, and to use light source as a small element LED, and the light transmitting material itself is resin-based material such as polyurethane, so it is light in weight and unbreakable Since it has a material, installation and maintenance costs can also be produced at a low price incomparable with neon signs, and the lifespan can also be used semi-permanently, which can effectively replace neon signs.

On the other hand, when the light-transmitting material according to the present invention is manufactured with various lighting fixture covers or lampshades, the light source is not exposed as it is and is refracted by a myriad of bubble layers, thereby producing beautiful colors that are clear and dazzling. It is possible to obtain the lighting effect that could not be realized by any existing lighting material, and it has a breakthrough effect to raise the interior lighting effect to high quality.It is a resin-based material, not glass, so it is easy to manufacture and there is no fear of breaking. It is light and has a useful effect such as being able to be applied very suitably as a lighting material.
