Barrier lowering, the diffusion movement of the carrier is greater than the drift motion, resulting in the P region of injecting holes into the N region, the N area of ​​electrons injected into the P region, such mutual injected holes and electrons meet, will produce the composite, when combined most of the generated energy in the form of light, and thus emitting light. The light emitting diode in the production, the material used is different, then it can emit different colors of light. The luminescent color of the LED light-emitting diodes: red light, yellow light, green light, and infrared light. LED luminous characters diode shape: round, rectangular, triangular, square, combination of shape, special shaped. There are four common LED light emitting diode application circuit, i.e. a DC drive circuit, the AC driving circuit, a pulse drive circuit, and discoloration of the light emission driving circuit. Limiting resistor in series, you should use the LED for indicating circuit, the resistor size should be to select the required operating current depending on the voltage and LED. LED light-emitting diode voltage drop is generally 1.5 ~ 2.0 V, typically take 10 ~ 20 mA operating current is appropriate. . The characteristics of the LED light emitting diode LED light emitting diode 1. The ultimate meaning of the parameters (1) allow power Pm: allows you to add positive DC voltage flow through the product of the maximum of its current across the LED. Exceeds this value, LED fever, damage. (2) forward DC current IFm: allows the largest positive DC current plus. Exceed this value can damage the diode. (3) the reverse voltage VRm: allow maximum reverse voltage plus. Exceeds this value, LED light-emitting diode breakdown. Ambient temperature range (4) working environment topm: LED light-emitting diode can work properly. Lower or higher than this temperature range, the LED light-emitting diodes will not work properly, the efficiency is greatly reduced. The LED light emitting diode 2. The meaning (1) of the electrical parameters of the spectral distribution and the peak wavelength: a LED light emitting diode issued is not a single wavelength, the wavelength is substantially shown in Figure 2. Seen from the figure, the light amounts of the light emitting tube, the light intensity of a particular wavelength λ0 lightbox, the wavelength for the peak wavelength. (2) the luminous intensity IV: the luminous intensity of the LED light emitting diode usually fingering line (refers to the luminous intensity in the direction of its axis) of a cylindrical arc tube. If the radiation intensity in the direction (1/683) W / sr, emitting 1 candela (symbol cd). General LED luminous intensity is small, luminous intensity commonly candela (mcd) as a unit. (3) spectral half width Δλ of: It represents the spectral purity of the light emitting tube. Figure 3 1/2 of the peak light intensity corresponding to the interval of the two-wavelength (4) The half-value angle θ1 / 2, and the viewing angle: θ1 / 2 the luminous intensity value of the axial strength of the value of half of the direction of the light emitting angle of the axial direction (normal). 2 times the half-value angle perspective (or half-power angle).

As one of the outdoor advertising industry, every day are engaged in their work, acrylic luminous characters in the industry is very small, luminous characters produced after Shanghai direct image of the simple message across,day after day, year after year, small luminous characters also have a big scholarship. In the end the luminous characters like? How to make? Application of places so many luminous characters, how to grasp the concept of design?

Font selection to choose the shop signs advertising font, common norms font in the font, there are some special font, according to his shop for groups to choose the font design.

Choice of colors, light the word white, yellow, red, green, blue, several common forms needed to select the color, as well as with color, can overall a color, can also be a mix of the two colors.

The choice of material, luminous characters of stainless steel, metal, galvanized sheet, acrylic production process Blister of punching, bending, etc., based on the need to choose different materials luminous characters production design.

These are simple for everyone to summarize the luminous characters making knowledge point, with the increasing demand of the advertising industry, the light-emitting Braille Production in the outdoor advertising industry is very important, although the vast industry luminous characters such as a drop in the ocean, but it is showing the value of advertising is great, luminous characters as an advertising word independent.

Acrylic material has excellent performance, such as excellent strength and toughness and translucent, during World War II is applied to the windshield of the aircraft, tanks vision mirror of the driver’s cab. 1948 the world’s first acrylic bathtub birth marks the application of acrylic enter a new milestone. Acrylic material process such as acrylic luminous characters, acrylic back carved.

Acrylic materials used in the advertising industry, history is not long, only use the outdoor publicity on the economic strength. First foreign-based, and then only in some well-known domestic enterprises popular, especially with chain nature of the enterprise, such as China’s Sinopec gas stations, the China Petroleum gas station A in the cake, hollyland; such as the financial industry The CITIC Industrial bankers brand; another example, the appliance industry.

To know why acrylic material is so popular, we must first understand the domestic outdoor advertising industry which forms of advertising. At present, the main form of advertising:

Neon light

Metal words, metal words, copper, stainless steel word

3, inkjet

4, other (trivision the computer screen)

Their advantages and disadvantages are as follows:

1 neon

Rainbow lights is also extremely extensive a form of outdoor advertising.

Main advantages:

Colorful, bright, high brightness, suitable for high-rise buildings.

Full of dynamic the neon advertising images and text can move, which is currently unmatched by other forms of advertising.

Moderate cost.

Disadvantages:

1) neon lights to be attached to the the metal word or metal sign face exposed thereon, the line is also exposed to the outer, and therefore less effective during the day, is not suitable for low-rise buildings or decoration, pay attention to the facade.

(2) neon tube light-emitting lines, therefore than the thin, the order to the whole word luminous density high cost of electricity consumption will keep pace with.

(3) in the low-rise buildings, high brightness, glare, light pollution is serious.

Metal word: common Tongzi word of stainless steel, metal words, stainless steel corrosion word

Advantages: strong, solid, and low cost.

Disadvantages:

(1) metal vulnerable to fade, rust, and other issues. Iron the word surface of metallic paint is easy to fade, fade, copper word processing bad easily oxidized.

(2) In addition to the word outside of galvanized iron, copper and stainless steel color limited.

(3) the material itself does not emit light, opacity, external lighting, plus The Lightboxes exposure to the shaped surface affect daytime effect beautiful wiring exposed on the outside, easily broken.

3, Printing:

Advantages: colorful, low cost, built-in to sprinkle light or outside lighting, the light source is easily damaged.

Disadvantages:

(1) Life is short. Existing lamp provincial judge cloth color quality can only support a year, some even less than a year began to change color, fade.

(2) firmly poor, especially within the lighting, no iron support wind can scratch, which is what we often see.

(3) thermal expansion and contraction, less capable of high and low temperature outdoors. The weather is too hot in the summer, easy expansion, and then a windy, it is easy to damage; winter cloth clamped tight, low temperature impact and easy to shrink, resulting in a number of small cracks, the long-term effect on the crack.

(3) thermal expansion and contraction, less capable of high and low temperature outdoors. The weather is too hot in the summer, easy expansion, and then a windy, it is easy to damage; winter cloth clamped tight, low temperature impact and easy to shrink, resulting in a number of small cracks, the long-term effect on the crack.

Such as computers, displays, single color, high cost, low brightness, has not been widely used.

These several forms of advertising, its advantages and disadvantages, and increasingly unable to meet the aesthetic requirements of businesses rising generation and application of new materials has also become a necessity. At this time, the acrylic material along with its many excellent physical properties to promote open.

Now we on the outside can see, there are many shops signboards luminous characters, these luminous characters making industry experts, luminous characters are many kinds of paper for LED luminous characters luminous characters are introduced, the LED acrylic plastic luminous characters composed of three parts of acrylic plastic panel, luminous characters box, and the word luminous light source:

Acrylic plastic panel:

Sheet material selection: imported sheet Japan Mitsubishi acrylic plate, American apple Caledon board, Germany the Romon acrylic panels, domestic sheet stretched spring acrylic plate, Taiwan thousand color acrylic plate, acrylic panels Xiamen Prosperity. The materials listed above acrylic plate by international industry quality system certification, and more assured in the production process and the use of raw materials, its advantages are mainly:

1. Plate of uniform thickness, the board is flat and smooth.

2. Light uniformity, color reproduction is good.

3. Good weather resistance, impact resistance, hard brittle, faded.

The production process is based on the production of the program, open the blister special mold. Usually the size of the luminous characters within 2.5mx2.5m can use 3mm hundred acrylic panels, using piecewise stitching, from drum height 2.2-3cm. Size recommended in the the luminous words above 2.5mx2.5m 5mm thick acrylic plate from the drum height of 2-3cm

WordBox luminous characters (shell type words):

Light-emitting every word box on the fine degree of processing can be divided into normal mode and fine mode.

1. The ordinary mode luminous characters cabinet:

2. Choice of materials: cold-rolled plate, aluminum plate, stainless steel plate, galvanized plate.

3. Luminous characters in the production process usually size 1.5m (extended meters) below the cabinet recommended that the state legislature to 0.8mm thick cold-rolled plate, the cabinet underside 1mm thick cold-rolled plate. Size 1.5m (extended meters) above the luminous word box Nippon 1.2mm thick cold-rolled plate, cabinet underside 1.5mm thick cold-rolled plate. After the completion of the bottom Nippon welding, painting or paint handling. The Nippon height of 10-12mm. This is the model used for outdoor visual distance of more than 20m.

4. The fine mode luminous characters cabinet:

Choice of materials: cold-rolled plate, aluminum plate, stainless steel plate, galvanized plate.

The difference is that production process production process and the normal mode the Box using fine spot welding, several polished, polished, and then dust-free paint, the the lacquering process of automotive sheet metal painting process.

Characters Light Source:

1. LED (light emitting diode) light source, LED luminous characters form the mainstream of the current luminous characters, LED cold light source 12 playful piezoelectric, its biggest advantage is energy-saving, durable, low repair rate, applicable to a wide range of I LED selection of the HP electronic chip, the brightness of the LED light source, long life, low energy consumption, about 15% of the energy consumption of the fluorescent light.

2. Neon light source is the biggest advantage of the neon light penetrating power, but its relatively high repair rate.

3. Pure Philips Pu lamp, ballast fluorescent tube light source. The brightness of the light source is stable and suitable for large luminous characters.

As one of the outdoor advertising industry, every day are engaged in their work, acrylic luminous characters in the industry is very small, luminous characters produced after Shanghai direct image of the simple message across,day after day, year after year, small luminous characters also have a big scholarship.

LED resin luminous characters, was also called as stainless steel luminous characters quintana luminous characters, two kinds called Yes widely, but the whole body luminous words mean something, because the whole body luminous characters, may also do acrylic quintana luminous characters. But there may be unsaturated resins do quintana luminous characters. Both quintana luminous characters, What is the difference in the end, we come to a good analysis.

First so-called acrylic plate is poly methyl methacrylate Polymeric Methyl Methacrylate (PMMA) sheet, which is made by Methyl Methacrylate (MMA) of methyl methacrylate monomer polymerization; another or from acrylic pellets extruded through the squeeze plate machine a. Acrylic board known as plexiglass. Perspex from the English Organic Glass, which refers to the PMMA plates are made from organic compounds MMA, transparency and transmittance as glass.

Acrylic quintana luminous characters, needless to say we should also know that the material is acrylic do. Specific approach, wherein a part of the first acrylic plate with the engraving machine or the same form as with other saws cut shaped, processed into a strip-like, in the same way and then the addition of the acrylic plate, used in a word boundary, then into the already The acrylic plate into the shape of the font or pattern heating bending bonding, the most commonly used adhesive 502 glue or chloroform. Is a complete acrylic bonding after quintana light emitting every word shell, installing lights can be installed. The advantages of acrylic luminous characters will not say more.

LED luminous characters classification

With the widespread use of LED, LED luminous characters more and more and more species, the following analysis currently on a wide range of applications in several luminous characters:

A. Word luminous resin

Word luminous resin shell by the word, the light source is composed of two parts. Wherein the housing portion using a liquid polymer resin material integrally pouring molding, or metal around edge resin inverted surface; emitting light source is used in the ultra-high-brightness semiconductor light-emitting diode (LED), the green light source of the 21st century. Word luminous resin can produce many kinds of quintana luminous characters, ordinary luminous characters, flat chromatic luminous characters, the most unique is the patent product of Long Shong, multi-dimensional chromatic LED resin luminous characters

II. Acrylic luminous characters LED acrylic luminous characters composed by three parts of the acrylic panel, light-emitting the word cabinet, and the word luminous light source. Word panel is carved out by the engraving machine on acrylic sheet surface box surrounded by metal or PVC, the word luminous light source high brightness LED light source.

III. Blister luminous characters

LED plastic luminous characters are composed of three parts of acrylic plastic panel, luminous characters box, and the word luminous light source. Word panel is sucked out of the acrylic sheet plastic machine a surface box surrounded by metal or PVC, the word luminous light source high brightness LED light source.

Exposed luminous characters

Color, colorful, full-color luminous characters exposed luminous characters divided by color. Monochromatic light the word is the from word shell lay the hole, and monochrome leakage lights. Colorful exposed luminous characters by the word shell lay the hole, and the colorful to leakage lights, colorful controller which, colorful gradients lighting. Exposed luminous characters full color leakage lights lay the word shell holes, and full-color, full-color controller constitute professional software to create program files placed in SD card, SD card into a full-color controller, hit the lights after leak can play FLASH animation, character animation, effects grade high luminous characters.

LED luminous characters have several luminous form led luminous characters signage added internal word in advertising advertising LED light points and made a word. Luminous characters of surface material durability, weather resistance, better transparent acrylic material commonly used. Translucent acrylic luminous characters, bright colors, do not fade, non-corrosive, does not affect the use of a rainy day. Are clear and bright three-dimensional billboards by day, night issued a colorful light, a dozen kilometers away, legible, has a very strong advertising effectiveness, its life expectancy of 10 years or more. LED luminous characters using a light-emitting diode as a light source produced luminous fonts. LED luminous characters available for the many advantages it beautiful daytime, night bright, energy saving, durable, to Liaoyuanzhishi quickly became popular.

Walk in any commercial street, you can achieve the the countless display panel grooving and rub shoulders with each other. “Street banner ‘should be the name instead. Signs here, you see.
