With the rapid development of science, technology and social economy, advertising and logo in today's world The industry is developing in the direction of high quality, fast, low energy consumption, electronic, information informatization and transnational. Lighting is an integral part of advertising and logo, along with advertising Identifies advancements in industry and lighting technology,The development trend of outdoor advertising sign lighting will be the diversification of lighting methods, artistic expression, scientific design, large scale, Intelligent control and management and standardization of lighting.

The advancement of lighting technology and the inherent characteristics of outdoor advertising media, such as the persistence of advertising effects, the diversification of shapes and the vastness of the installation site , have led to the variety of outdoor advertising. Constantly increasing, such as storefront advertisements, rooftop advertisements, advertising towers, billboards, pole type (light poles, telephone poles, etc.) advertisements, dynamic stereoscopic advertisements, aerial ads, etc. Therefore, the methods of advertising are also increasing, forming Neon lights, flood lights, internal light boxes, fiber optic lighting, LED lighting, invisible lighting, etc.Various lightingLighting The development trend of the coexistence of methods, in the light source of advertising light box LED injection molding module occupies important position.

Flexible lightbox advertising with its unique advantages, in advertising lighting is very popular, and its application prospect is very ideal. The reason is that compared with iron leather light boxes, film light boxes, frosted glass light boxes, diffuse transmission plexiglass light boxes and even neon signs, the flexible light boxes have the following outstanding features Advantages:

(1) The fabric has good diffuse light transmission performance, and the visual effect is good when viewed from different angles; using thermal transfer technology, various text and << /span>The color pattern is transferred to the cloth, and the visual effect is the same whether it is day or night;

(2) fabric is soft, high strength, anti-ultraviolet aging and anti-static, and can be used for a long time without direct damage or climate influence. For example, the Autolon 4 light box cloth made in Germany has a guarantee period of 5 years and a service period of 10 to 15 years; span>

(3) the way of rolling the fabric makes the transportation more safe, economical and convenient, and it is equipped with aluminum alloy or stainless steel box frame. It is easy to install and has good weather resistancegood, such as Autolon 4 light box cloth, which can resist wind speed of 100km/h;

(4) Because the light box is equipped with anti-microbial growth, anti-pollution and easy to clean, it is convenient for maintenance and management. Cleaning the cloth, overhauling and replacing the light source do not requireremoval of the cloth, just open the upper or lower cover of the light box.

In view of the advantages and characteristics of flexible light box advertising, the following describes the light box light source-LED injection molding module features and application.

Common LED injection molding modules have the following features:

1. It can present seven colors of red, blue, purple, green, yellow, cyan and white, seven-color jump, seven-color gradient, seven-color jump, seven-color gradient and other effects;

2. The light source is TOP5050led, with no light spots, low light decay and good consistency;

3. The product has low power consumption, high brightness, long service life and maintenance-free;

4. The shell adopts injection molding process, with beautiful and unique appearance and good heat dissipation effect;

5. The waterproof level can reach above IP65;

6. Low voltage input, safe and reliable to use;

7. LED injection molding module 20 units are a string, LED injection molding module adopts a series-parallel hybrid circuit, and a single module can be cut off.

Application scope of LED injection molding module

LED injection molding module is one of the LED modules. Compared with other types of modules, the light-emitting angle is large, the brightness is high, and the light decay is low, so it is more widely used.

1. Advertising signs, lighting signs, (ultra-thin) light boxes, three-dimensional lighting characters, blister characters, other advertising lighting, etc.;

2. Hotel, KTV, shopping malls, entertainment city interior (dark slot), exterior wall lighting, landscape layout, stage decoration, urban lighting, etc.

3. Partial decorative lighting for home shoe cabinets, wardrobes, hidden ceilings, exhibition halls, art halls, museums, offices, reading rooms, etc.;

LED injection molding module installation features

The first step: Calculate the total power of the LED injection molding module, so as to configure the appropriate LED switching power supply (the power supply should be configured with 80% power output).

Total power consumption = number of modules × power consumption of a single module

For example: 300 three-lamp 3528 SMD modules, the rated power consumption is 300×0.25=75W

Step 2: Fix the LED injection molding module

LED injection molding module fixing method:

1. Stick double-sided tape on the back of the plastic case for initial fixation, and then use glass glue for auxiliary fixation.

2. The glass glue is directly fixed; the surface of the module should be wiped clean or properly polished before installation to ensure that the contact surface is clean.

3. The bottom of the plastic case is fixed with screws.

Step 3: Connect the power

After all the LED injection modules are installed, you can use 0.75mm or 18AWG wires to connect to the power supply. The distance between the power supply and the module should be within 5 meters. If the font size is large, the power supply can be built in without affecting the heat dissipation of the module.

LED injection module power supply installation precautions:

1. The special switching power supply for LED injection molding module should pay attention to waterproof measures.

2. The output voltage of the switching power supply should be adjusted according to the characteristics of the LED injection molding module, and the voltage adjustment button should not be rotated at will during use!

3. There are positive and negative poles for the LED injection module. When installing, pay attention to the corresponding positive and negative poles. If the positive and negative connections are reversed, the LED injection module will not emit light, but it will not damage the LED injection module. Just change the connection. Can. Not adjustable big and small voltage!

4. During the installation of the LED injection molding module, it is required to use double-sided tape or woodworking glue to firmly stick the module slot and the plastic bottom plate. When using double-sided tape, glass glue must be applied again, otherwise the module will fall off under long-term sunlight exposure. This is very important!

5. When the LED injection molding module is installed in the blister or the box, try to form as many loops as possible, and the number of modules in series should be as few as possible, not more than 40 groups, and the colorful series should not exceed 20 groups, otherwise it will be subject to voltage drop Influence, and it is very likely to cause excessive single-channel current to burn out the circuit board!

6. LED injection molding modules without waterproof treatment should prevent rainwater from entering when they are installed in blister characters or boxes.

7. The spacing of LED injection molding modules can be adjusted according to the actual situation such as brightness and module size, and the number per square is generally between 50-100 groups. When arranging the LED injection molding module, attention should be paid to the uniformity and brightness of the light; the distance between the LED injection molding module and the font edge is generally 2-5 cm, and the vertical and horizontal distances between the LED injection molding module and the LED injection molding module are It is recommended to be 2-6CM. When installing the LED injection molding module, do not push it. Squeeze the components on the LED injection molding module to avoid damage to the components. The connecting wires inside should be fixed on the floor with glass glue to avoid shading.

8. The distance between the LED injection molding module and the surface of the light-emitting body should be well controlled, so as to ensure the uniformity and brightness of the light, so the thickness of the light box is also very important.
