Description

Outdoor identification system

Technical Field

The invention belongs to the technical field of outdoor identification electric appliances, and particularly relates to an outdoor identification system.

Background

The outdoor identification electric appliances are widely applied, and comprise advertising boards, identification boards, direction boards, guideboards and the like.

The direction board is generally placed near the company, so that others can find the company quickly; the roadside sign can enable people to know which road to choose and how to walk; the property district of the real estate company can better facilitate people to know the geographical position of the district; such as: gasoline stations, highways, hotels, etc., are found in many locations. The signboard can be used as a billboard at the door of a place such as a market, a hotel, a bank, a hotel and the like to display each product or service which needs to be popularized.

The LED identification electric appliance is a rapidly developed indication board material door, can replace neon lamps, and can be used for lamp box signboards and luminous characters of restaurants, shopping malls, convenience stores, open squares and buildings. The LED lamp has the advantages of high brightness, long service life (up to 15 ten thousand hours without maintenance), high efficiency, convenient installation, reliable performance, high cost performance and the like, and is widely applied. In addition, as an indication or an instruction text of lower height of the general outdoor, ACRYLIC (improved organic glass) can be selected for manufacturing, the manufacturing method is mainly computer engraving, and the surface treatment is usually baking varnish. The process has the advantages of good processing and forming consistency, simple installation and quite unusual weather resistance performance. The manufacture of the outdoor sign has the materials or the expression forms of glass fiber, organic glass, computer spray painting and the like, and the detailed description is omitted because the effect is more traditional.

Due to the scattering effect of clouds, water drops or haze and the like in the atmospheric layer, ambient light can be scattered in different environments to different degrees, so that different colors can be presented; for example, in early morning or evening, sunlight obliquely passes through the atmosphere, and has a long optical path in low-level atmosphere, the sunlight is greatly attenuated due to the scattering and absorption of light by air molecules, water vapor and dust particles in the atmosphere, and the light attenuation conditions of various colors are different, so that the sunlight passing through the air layer shows different colors, and the light can reach human eyes after being scattered by scattering particles in the atmosphere. This further increases the complexity of the sky color. The components and the state in the atmosphere are constantly changed to form a reddish rosy, the ambient light is reddish, and the ambient light is yellowish when the wind-blown sand is large or the haze is large. This is the case because some of the light waves in sunlight are refracted or scattered, while the red and yellow light have longer wavelengths and therefore lower refractive indices and greater transmission. However, the outdoor sign device generally uses a color with a longer wavelength as the illumination color of the sign lamp, so that the transmission range is wider and the sign lamp is perceived by more people or more distant people, and therefore the use of the sign device is reduced by the ambient light.

Moreover, when the ambient light intensity was too high, the illumination intensity of sign electrical apparatus was limited, owing to the management and control power to light pollution, the illumination intensity of its sign lamp can not infinitely increase to the sign electrical apparatus, consequently urgently needed a sign electrical apparatus of adjustable sign lamp illumination intensity to make the signboard promote its all-weather marking effect by a wide margin under the condition that accords with not producing optical pollution.

In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.

The outdoor signboard usually adopts stainless steel mirror surface or wire drawing board, titanium gold plate, glass, acrylic plate, copper plate, aluminum plate, cold rolled plate, marble, stainless steel pipe, solid wood as surface material, adopts stainless steel pipe as internal structure, uses black metal section as reinforcing material, and uses led, plasma lamp, neon lamp, light guide plate and other related materials as luminous source.

Metal working

The metal is welded, bent, washed, lathed, water-cut, wire-cut, polished, wire-drawn, electroplated, oxidized, corroded and baked with varnish. The surfaces of the acrylic and the glass are comprehensively processed according to design drawings by adopting the processes of silk-screen printing, instant pasting, carving, sand blasting and the like. The perfect key of the identification lies in the design concept and the rationality of the manufacturing process.

Character art

The role of the logo is a very important component of the primary guidance, which is the starting point of the guide system of the sign according to the principle of hierarchical guidance, so that the selection of appropriate materials, processes and colors play a decisive role in the overall image effect.

For a long time, traditional outdoor lettering has been around several traditional technologies.

Galvanized iron character

The galvanized iron stereo artistic character is made up by using galvanized iron plate whose thickness is 0.8-2.0 mm, cutting according to character form, using proper depth as character side skirt, connecting the joints by means of tin soldering, polishing corner of finished product, spraying paint on its surface and fixing it on wall by means of plain code or cipher code. The process has the advantages of low cost, but because the galvanized iron plate is made of heavier materials (about 7.85kg/mm per square meter), characters with the top more than 3m are difficult to adopt thicker panels, the wide character-shaped painting surface is uneven and slightly sunken, the rust resistance of the galvanized iron is reduced due to cut edges, the product can leave unsightly rusty spots on the wall due to rust corrosion after being used for about one year, the surface paint film is difficult to firmly adhere due to charge of the galvanized plate, the service time is long, and the paint film can be detached.

Stainless steel character

Copper characters and stainless steel can be called noble metal compared with galvanized plates, and the metal texture is more unique, so that more people always want to make the copper characters and the stainless steel appear in the original view, the copper is also metal which is easy to oxidize, so people often electroplate the copper or finish the character processing and then polish the surface of the copper characters and make the surface of the copper characters and the stainless steel into closed paint (rust prevention) to enable the copper characters and the stainless steel to flash, and people utilize the characteristic of stainless steel to adopt the polished (hairline) surface which is matte treatment or directly adopt 8K (mirror surface) treatment to make the copper characters and the stainless steel dazzling and colorful, and the copper characters and the stainless steel belong to one of bright groups in the building genre, but the two treatments have common defects and lack individuality because people select the process for many years, and the individuality is not revealed; in outdoor shining sunlight, the strokes of characters may be unclear due to the refraction of metal, and in rainy days, the metal may also appear blurred due to the loss of luster or gray.

Neon lamps: the neon lamp is generally characterized in that a surrounding edge modeling or a plane laying neon tube is added on the basis of galvanized iron craft characters, and stroboflash or scanning effects are controlled by a single chip, so that the neon lamp has the advantages of being very attractive at night and easy to recognize, has the defect of poor daytime effect, can be displayed only by character modeling, but has fuzzy characters due to the shielding of the tube, is relatively complex to maintain and has relatively high power consumption.

Paste pyramid

Less hospitals adopt the process, on one hand, the value is not so good (in terms of real material process), and on the other hand, the business site can better lodge the process, which is not described in more detail.

Lamp box character: the technology of stainless steel and aluminum characters is integrated, the greatest breakthrough is that the characters emit light by themselves, and the illumination at night does not need to be performed by means of external light.

Aluminum plate word

The aluminum plate character has the following characteristics: 1. the aluminum plate has the advantages that the aluminum plate is light, the weight per square meter is 2.71kg/mm, so that the panel can be as thick as 3mm or more, and the flatness of the surface of the character is greatly improved; 2. the aluminum plate is not easy to rust, the oxidation of the aluminum plate is slow, and rust stains cannot pollute the wall; 3. the paint is easy to color, a paint film is easy to adhere, and the surface durability can be compared favorably with that of the automobile finish paint if the paint is processed properly; 4. installation is convenient-installation is much lighter due to the low weight. The disadvantage is that the cost is slightly high and needs a professional factory for manufacturing. The welding process is similar to stainless steel, but the aluminum plate is soft, the flatness and firmness of the surface of a finished character can be directly influenced by the level of a processor in the welding process, but the process is accepted by more hospitals recently because the maintenance cost is extremely low, and the process is a measurement standard of 'cost performance' of operators.

Luminous character

The LED is a rapidly developed door of indicating board materials, can replace neon lamps, and can be used in lamp box signboards and luminous characters of restaurants, shopping malls, convenience stores, open squares and buildings. The LED lamp has the advantages of high brightness, long service life (up to 15 ten thousand hours without maintenance), high efficiency, convenient installation, reliable performance, high cost performance and the like, and is widely applied. In addition, as the indication of lower outdoor height, the legend can also select ACRYLIC (improved organic glass) to make, the making method is mainly computer engraving, and the surface treatment is usually baking finish. The process has the advantages of good processing and forming consistency, simple installation and quite unusual weather resistance performance. The outdoor sign board is made of glass fiber, organic glass, computer spray painting and other material or expression form, and has traditional effect.
