Luminous characters of LED luminous characters

The exposed luminous characters are iron characters, stainless steel word characters, aluminum characters and titanium characters, and a single LED waterproof light string is installed by punching holes on the surface. Commonly used materials for making exposed luminous characters are: acrylic board, galvanized board, stainless steel and titanium board.

First, the production process of exposed luminous characters

1. Use an automatic punching machine to perform numerical control punching on files with luminous characters (the aperture is determined according to the LED size);

2. Laser cutting the surface of luminous characters and welding the edges of three-dimensional characters (the same as baking paint);

3. Polishing the corners of characters without burrs;

4, baking paint treatment;

5. Install waterproof strings of LED lamps (the waterproof connection string of each lamp is equipped with rubber sleeve, which is easier to maintain).

Second, the method steps of exposing LED luminous characters

1, LED outdoor signs need tools: 30W or 40W soldering iron, solder, electric drill, glue gun, screwdriver, etc.

2.LED outdoor signs need other materials: molded baked iron characters, wires, and special power supply (DC5V) for LED signs.

3. Drilling: Fix the lettering of the purchased molded iron in a proper position, and drill holes (9mm) with an electric drill. The spacing depends on the installation height and manufacturing cost of outdoor brands. The center spacing of LEDs is 10-30mm, with small spacing, high brightness and high cost.

4. Plug in the lights: clean up the drilled holes and plug in the lights one by one.

5. Connection: waterproof LED light strings, each string has reserved terminals. Generally, the red terminal is connected to the positive pole of power supply, and the black terminal is connected to the negative pole of LED special power supply. It is best to put the power supply in a waterproof power supply box.

6. Test aging: After all LEDs are connected, check the ones that are not bright, and then conduct 48-hour aging test.

7. Transport to the site, and install the scaffold on site.

Thirdly, the advantages and characteristics of large exposed luminous characters and internal luminous characters are compared.

Compared with plastic characters, exposed luminous characters are more cost-effective. After analysis, it has the following characteristics:

1, exposed luminous characters Because the lamp is exposed and is not affected by other things, the brightness is higher than that of blister luminous characters.

2. The cost is relatively low. Conventional plastic characters, also called light box characters, are composed of two sets of characters and the lights inside. So the cost is relatively high. The LED external luminous characters can be made of iron or stainless steel, and then the lamp can be installed by stamping, which saves the cost.

3, the light is even, because plastic characters are limited by the size of strokes, there is no way for ordinary modules to paste strokes, so there will be different brightness of words. The external luminous character is installed with a single led lamp, so this phenomenon does not exist in the external luminous character of LED (unless the lamp is broken).

4, easy to maintain, the lamp beads with characters exposed can be removed from the outside, and the literal characters of the blister light box need to be removed. For high-rise buildings, it takes a lot of cost to disassemble, repair and put back the words. You can build a shelf or rent a hanging basket if you need it.

5, size restrictions, generally exposed characters do not have to worry about the size of the characters, while plastic characters are limited by plastic machines. Words that are too big need to be spliced, which will greatly affect the appearance and have certain seams. Led exposed luminous characters, iron sheet punched luminous characters, dew point luminous characters, colorful dynamic signs, super-large and ultra-small special luminous characters, underwater special luminous characters, led glass full-body luminous characters, LED luminous characters, large-scale luminous signs, LED exposed perforated luminous characters, metal perforated luminous characters, all-in-one service for production and installation. Such as iron perforated luminous characters, metal hollow luminous characters, stainless steel perforated painted characters, dew point LED luminous characters, external luminous signs, billboards and so on.

Four, the production process and characteristics of exposed lamp luminous characters

1, waterproof, energy-saving and safe: as we all know, LED luminous words have low power and low power consumption. Because the output voltage is low, it is safer. Because the LED external light source we use is waterproof, it can be used normally in rainy days without worrying about burning out.

2, not limited by size: Generally speaking, LED blister and other internal luminous characters are mostly limited by the blister machine, and many large characters need to be spliced, which will destroy the beauty of the characters. The exposed characters are generally bent by plasma cutting, so the size is not limited by the machine. It's more beautiful without splicing.

3, not limited by the color of the characters: generally, the internal luminous characters are limited by organic boards, such as red plastic characters, and generally, a red light source is put inside to emit red light, while the exposed luminous characters are not limited. You can bake the characters into various colors of paint, and order whatever color you need at night, which is completely unaffected by the people at the bottom. Moreover, because Chinese characters are high from the ground, LED exposed lights are not obvious during the day.

4. Convenient maintenance: Although LED lights rarely break down, they need to be repaired in case of poor wire contact or special circumstances. This kind of LED exposure character only needs to be hung from the sky to the broken position of the billboard, and the broken lamp can be pulled out from the front and replaced.

classify

1. According to the position of the lamp, LED luminous characters are divided into built-in luminous characters and exposed luminous characters.

2. Exposure luminous characters are divided into monochrome, color and full color luminous characters according to color. Monochrome luminous characters are composed of perforated character shells and monochromatic light leakage lamps. Color exposed luminous characters are composed of perforated character shell, color leakage lamp and color controller, which can gradually change color after lighting. Full-color exposed luminous characters consist of perforated character shell, full-color light leakage lamp and full-color controller. Make program files with professional software, put them into SD card, and insert them into full-color controller. After lighting, the luminous characters are leaked, and FLASH animation and character animation can be played, with very high effect. The effect of full-color scanning luminous characters in Longxiang advertisement is very high. trait

App application

Using waterproof LED light string to make outdoor luminous characters and outdoor signboards highlights brand and fashion, and greatly improves the scale and grade of businesses. Mainly used for: outdoor signs of star-rated hotels, roof signs of hotels, exterior signs of hotels, hotel doorplates, exterior signs of hotels, LED perforated characters on exterior walls, KTV signs, signs of sauna bath centers, hotel signs, store signs, doorplates, digital plaza signs, property building signs, shopping plaza signs, etc. 1, LED outdoor signs need tools: wire cutters, electrical tape, screwdrivers, etc.

2.LED outdoor signs need other materials: molded baked iron characters, wires, and special power supply (DC5V) for LED signs.

3. Drilling: Fix the lettering of the outsourced molded iron in a proper position, and drill the hole (8mm) with an electric drill, preferably with a lathe. The spacing depends on the installation height and manufacturing cost of outdoor brands. Generally, the spacing between LED centers is 20-30 mm, which is small, high in brightness and high in cost.

4. Plug in the lights: clean up the drilled holes and plug in the lights one by one.

5. Connection: make parallel waterproof LED light strings, each string has reserved terminals, generally a string of 15, and there will be no voltage difference (which can reduce the light difference). It is best to put the power supply in a waterproof power supply box.

6. Test: After all the LEDs are connected, check the ones that are not lit, and then test for 2 minutes.

7. Transport to the site, and install the scaffold on site. The biggest feature of LED three-dimensional luminous characters is 1, and the fonts are bright and eye-catching at night (a new ultra-bright light source is installed, which has a long service life and makes it shine with the color of acrylic board).

2, strong three-dimensional sense.

3. Bright colors (acrylic boards of various colors can be selected at will, and the colors of wallboard and panel can be combined at will).

Manufacturing method of LED three-dimensional luminous characters;

; Calculate the number of LED modules: the modules are arranged at equal intervals, the visual brightness of the module spacing needs to be between 3-6cm, and the thickness of luminous characters can be selected between 5- 18cm.

Step 2 > > Install the module: ① Clean the installation surface; ② Stick it on the bottom of the module with double-sided tape; (3) uniformly arranged and connected; (4) install the trough plate and measure the effect; ⑤ Final product. 1, LED has a short service life.

The theoretical life of LEDs produced by regular manufacturers is generally around 80,000 hours. However, many LED modules began to be replaced frequently within one year, which brought a lot of troubles and economic losses to customers and advertisers.

2. The color will fade soon.

The newly installed luminous characters are pure and bright in color, but the color is obviously darkened after less than one year of use. Let the font be red or not, and green or not is ugly.

3. The color is uneven and the color difference is obvious

Mainly manifested in the large luminous characters made of pure white LED. When assembling, the performance of a single module is not obvious. After the whole font is assembled completely, the color difference is obvious. The whole word is like a map, white, blue and yellow.

4. It doesn't light up suddenly or it doesn't light up when it is on.

Some strokes and the whole font suddenly don't light up or don't light up when they are open. After a period of use, the light source of some or the whole font began to blink, and it was on or off until it was completely extinguished.

5, the output power is large, and the energy saving is not obvious.

Font output power is large, and energy saving is not obvious. 1. Buy qualified LED single lamp particles produced by regular manufacturers (quality parameters provided by manufacturers are required) and make your own modules. Don't go to the electronic market for cheap to buy LED single lamp particles or manufactured modules. If you need to buy a module, you should see how many resistors are installed on the module. It is best not to use a module with only one resistor. The resistor plays a role in limiting current in the module and is easy to generate heat. If it is used continuously for a long time, once the resistor is burnt out, the module will not light up. LED lights generally don't break. Don't throw away the module, just change a resistor with the same resistance and it can be used normally. This can save money for production units. In order to reduce trouble and save money, it is best to choose a module with two resistors. In addition, it is necessary to know the production facilities of suppliers who make modules and see if they use anti-static facilities when making modules. If there are no additional anti-static facilities, even if the resistor is not burned out in use, the LED lamp is easily damaged by breakdown.

2. The safe use current of 2.LED lamps is generally 20 mA. If it exceeds this value, although the brightness will increase, the color attenuation will be obviously accelerated. Therefore, when purchasing led modules, it is necessary to test the output current value of the assembled LED modules. The brightness below 20 mA is not enough, and the brightness above 22 mA affects the life of LED and accelerates the color decay.

3. White LED lamps should be separated by beam before leaving the factory (some LEDs without beam separation are pure white, some are blue and some are yellow). Spectrophotometer is expensive, and generally small factories don't have this kind of equipment, so the white light produced is generally taken to large factories for spectroscopic color separation. Because it is not the product of our own factory, the color separation will not be so detailed. Some small factories don't split colors at all. They usually attract customers at low prices. So when buying white LEDs, don't blindly covet cheap ones. Be sure to buy LED single particle lamps or modules of the same manufacturer, batch and color number to make luminous characters of the same batch.

4. Most of the light-emitting modules sold in the market are connected by connecting wires. In this way, it is convenient and quick for advertising manufacturers to install light-emitting modules. However, some new problems have emerged. During the long-term use of the connector, it is easy to be oxidized by moisture in the air, resulting in poor contact, resulting in instantaneous or complete power failure of some or all circuits, resulting in flashing or unlit font light source. The solution is:

(1), the module is manufactured without connectors, and it is directly connected with copper tin-plated wires and then welded with activated carbon solder.

(2) Make totally enclosed hollow three-dimensional luminous characters with artificial agate to isolate the contact between light source and air.

5. Try to use a five-lamp LED module, so that the number of lamps does not change and the power is reduced by two fifths. 1, LED monochromatic luminous characters (red, yellow, white, green and blue);

2, LED two-color lights;

3, LED multicolor luminous characters;

4, LED colorful color-changing luminous words (gradient, jump, color change, color flashing). 1, high brightness

Especially suitable for advertisements and big characters of high-rise buildings and luxury houses.

2, simple maintenance

It is simpler and easier to maintain than plastic characters and neon characters.

3. Save electricity and energy

Compared with any advertising words with the same brightness, it saves more than 80% energy.
