Luminous character introduction:

Luminous character is a kind of luminous character which is made by the light source of the light emitting tube. LED luminous characters with its beautiful day, bright night, energy saving, durable many advantages have been on the market, with the trend of rapid popularity.

Profit cost:

The profits from luminescence are considerable. If you do not need the word light, do the general word, only sell the word shell can also. The gloss of the single hand-made word shell is also good-looking and bright than the acrylic word carved by the machine. Compared with acrylic plastic characters, the brightness of the same light source is more than double. It will not fade in 5 years, and it is not afraid of wind and rain for maintenance-free design, and its life is greatly improved. Compared with neon words, the power consumption of about 20 watts per square is only about one-tenth of that of neon words. Ten times longer life!

Q&A

LED light characters in the use of 5 common problems and solutions

1, LED short service life: the theoretical service life of LED produced by regular manufacturers is generally about 80,000 hours. And a lot of light-emitting words do not use enough a year began to frequently replace the LED module, to customers and advertising manufacturers have brought a lot of trouble and economic losses.

The solution:

Purchase a qualified LED single lamp particle produced by a regular manufacturer (need to have the quality parameter description provided by the manufacturer), and make your own module. Do not buy a single LED bulb or a made module cheaply in the electronics market. If you need to buy a module, you should see how many resistors are installed on the module, and do not use a module that installs a resistor. The resistance plays a current limiting role in the module and is easy to heat up. After long continuous use, once the resistor burns out, the module will not light up. LED lights don't usually break. Do not throw away the module, just replace a resistor with the same resistance value can be used normally. This can save money for the production unit. In order to reduce trouble and save money, choose a module with two resistors installed. In addition, it is necessary to understand the production facilities of the supplier making the module to see if they use anti-static facilities when making the module. If there is no additional anti-static facilities, even if the resistance is not burned out in use, the LED lamp is easily damaged by breakdown.

2, the color decay is very fast: the color of the newly installed luminous word is pure and bright, and the color can be obviously dimmed in less than a year. Make the font red is not red, green is not green is very ugly.

The solution:

The safe use current of LED lights is generally 20 mA, more than this value, although the brightness will increase, but the color attenuation will be significantly accelerated. Therefore, when buying the assembled LED module, be sure to test its output current value. Brightness below 20 mA is not enough, more than 22 mA affects the life of the LED, so that the color decay is accelerated.

3, the color is uneven, the color difference is obvious: mainly manifested in the pure white LED production of larger luminous characters. In the assembly of a single module performance is not obvious, the entire font assembly is complete, the color difference is obvious, the entire literal like a map, a white, a blue, a yellow.

The solution:

White LED lights before leaving the factory must go through the spectral separation (not through the spectral separation of the LED some of the light emitted pure white, some blue, some yellow), the spectral separation instrument is expensive, the general small factory does not have this kind of equipment, so the production of white light is generally to the big factory for spectral separation, because it is not their own factory products, the spectral separation will not be that N carefully. Some small factories simply do not divide the color. They usually attract customers at low prices. So in the purchase of white LED do not blindly greedy cheap, must buy the same manufacturer, the same batch, the same color LED light tube single particle lamp or module to make the same batch of light word.

4, part of the font stroke, the whole suddenly not bright or when the light is not bright: the luminous word in use for a period of time after the local or the whole font light source began to blink, bright when not bright, until not bright. Most of the light-emitting modules sold on the market are connected using plug wires. In this way, the advertising manufacturer can install the light module easily and quickly. However, there are also some new problems, because the connector is easily oxidized by the moisture in the air during a long time of use, resulting in poor contact, so that the partial or all circuits are instantly powered off or powered off, resulting in the font light source flashing or not bright.

The solution:

A. Do not need to connect the plug-in when making the module, directly connect with copper tinned wire and solder with activated carbon.

B. Artificial agate is used to make fully sealed hollow three-dimensional luminous characters to isolate the contact between the light source and the air.

5, font output power is large, energy saving is not obvious.

The solution:

Try to use a group of five lights LED light module, so that the number of lights does not change, while the power is reduced by two-fifths.

Basic classification

With the wide use of LED, LED luminous characters are more and more types, let's analyze several widely used luminous characters:

Resin

Resin luminous characters are composed of two parts: a shell and a light source. The shell part is made of liquid polymer resin

Integrated casting molding, or with metal edge resin inverted surface; The light source uses ultra-high brightness semiconductor light emitting diode (LED). Green light for the 21st century. Resin luminous characters can be produced a lot of varieties, there are whole-body luminous characters, ordinary luminous characters, flat color luminous characters, unique is three-dimensional LED resin luminous characters.

acrylic

It consists of acrylic panel, luminous word box and luminous word light source. The word panel is carved out by the engraving machine on the acrylic sheet according to the graphics input by the computer.

Plastic absorption

LED blister light word is composed of acrylic blister panel, luminous word box, and luminous word light source three parts. The word panel is made of a blister machine on the acrylic sheet pressed at high temperature to create a concave and convex surface.

expose

Exposed luminous words are divided into monochrome, seven-color, full-color luminous words according to color. The monochrome luminous word is composed of a perforated word shell and a monochrome external leakage lamp. The seven-color exposed luminous word is composed of a well-perforated word shell, and a seven-color external leakage lamp and a seven-color controller, which can be gradually changed after the light is played. The full-color exposed luminous word is composed of a well-drilled word shell, a full-color external leakage light and a full-color controller. The program file is placed into the SD card using professional software, and the SD card is inserted into the full-color controller. After the light is played, the external luminous word can be played with FLASH animation and character animation.

LED exposed luminous character

1, high brightness, product brightness exceeds all other lighting equipment.

2, windproof, waterproof, dustproof can be all-weather operation, not affected by bad weather conditions.

3, strong visual impact, rich color, font, pattern, animation can be made at will.

4, to replace the traditional neon light and other indoor and outdoor signs, lighting system in a flexible way.

5, energy saving, low operating costs, product power consumption is small, only one tenth of the traditional neon.

6. Good advertising efficiency. The combination of static and dynamic display mode, rich and changeable display content, low operating cost, high security design and high service life can greatly improve the return on investment of advertising investors, so that advertisers and advertisers can perform unlimited wonderful advertising content through limited funds, thus giving full play to the advantages of outdoor advertising media. The real realization of acrylic luminous word advertising investors and advertising users win-win.

Price calculation

Some people who have just done advertising often question, how should the production of luminous words be quoted and calculated? According to the usual application habits and industry rules to communicate with you:

Generally divided into three cases to calculate:

1, the luminous word area of more than 1 meter is calculated by length * length. Do word price = area * price per square, for example: for example, to make a 1.2-meter-high, 1-meter-wide word, quote 800 yuan per square, then do word price = area 1.2*1.2 (according to the stroke of the word * stroke) *800=1152 yuan.

2, 1 meter below the luminous word area according to the length * per centimeter of the price, for example: for example, to make a high 60 centimeters, 40 centimeters wide luminous word, quote quote by centimeter, if 8 yuan per centimeter, then do the word price =60 (according to the word stroke) *8=480 yuan

3, 20 cm below the word, according to the number of price, specific price according to the company.

Instructions

1, explain whether to install, and installation costs, etc., installed in a relatively high place, how much high-altitude installation fees.

2, generally speaking, the larger the word, the higher the unit price. Because the words are large, the strokes are wide, and the requirements for materials are high. This, everyone should know oh.

3, the production contract should explain whether it is the customer's own delivery, or the company's delivery, and if the logistics is far away, the logistics cost should be explained.

Light source selection

LED can save a lot of energy for the country and the user, and save a lot of hours for the contractor. The development of LED application technology has added new vitality to the highly competitive advertising industry. Its unique and different luminous situation is widely used in the production field of advertising products. Different specifications of leds have different lighting angles and different brightness. So, how to choose the right LED for different products, so that it can play a role, but also to minimize the cost? The application and use of LED in luminous characters Note that three-dimensional luminous characters have the following requirements for the light source:

First, the complexity of LED luminous characters and the different specifications of different projects require the versatility of the light source without font limitation;

Second, due to the installation of LED light word maintenance is extremely inconvenient, in order to reduce maintenance costs, the light source is required to have a long life;

Third, LED light word to have enough brightness requirements of the production of LED light module, with the above functions. There are two kinds of LED light sources suitable for three-dimensional luminous letters: piranha and small straw hats. Piranha luminous module is suitable for luminous characters with a wall height between 8-10cm.

Generally speaking, 3 and 5 piranha light Angle of 90 degrees and 120 degrees. At this distance, the piranha luminescent module applied to the plastic letters can radiate light. Not only the number of modules is saved, but also the utilization rate of light intensity is just right after the screen brightness meter test. For the character wall is shorter, the shape of the plastic luminous words and carved luminous words, it is necessary to use the flat head piranha module and the small straw hat luminous module at a luminous Angle of about 160 degrees. The larger light radiation area can reduce the amount of module, and the shorter wall improves the luminous brightness of the font. The two organically combined, following the law of conservation of energy, but also reflects the importance of the correct choice of LED.

It is worth noting that in the process of using LED light emitting modules, we must pay attention to the problem of voltage drop. Never make just one loop, from end to end. Doing so will not only cause the brightness between the head and the tail to be inconsistent due to the different voltage, but also cause the problem of excessive single current burning the circuit board. The correct approach is to parallel as many circuits as possible to ensure a reasonable distribution of voltage and current. In addition, if anti-corrosion materials need to be used inside the word chamber, white primer is used to increase its reflection coefficient.

White LED as a semiconductor light source, compared with the traditional lighting source, its power consumption is only equivalent to about 20% of the latter. The service life is up to 100,000 hours, which is dozens of times that of ordinary lamps. It has good reliability and low maintenance cost. The use of low voltage, the working voltage is generally below 5V, in addition to the liquid crystal backlight of portable machines, it can also be used for field lighting, remote mountain lighting, miners' lamps and water environment lighting. The switching time is short, the response time can reach 1 microsecond, and the general lamps are several milliseconds (the response time of the light source in use is 200 milliseconds). Environmental protection, no mercury and other harmful waste, solid and not easy to break, reduce waste pollution to the environment. LED lights do not contain infrared and ultraviolet components, no radiation pollution, and DC drive, no stroboscopic, is an environmentally friendly light source to protect eyesight. With the widespread use of LED and the improvement of performance, a new lighting revolution is coming has become the consensus of people, then what will this expected change bring to people: this is the development of LED application products and guide the development of the market concern.
