advertising logo - a symbol of urban prosperity, amazing and applauded! In the sun, she is not only the figure of various brands, but also the weather vane of the urban economy and construction, she also helps people to determine the orientation in the unfamiliar city; in the night, she is a streamer It is colorful and dominant, attracting many crowds like a magnet.

In today's highly developed information society, with the continuous development of the market economy, outdoor advertising and logo As an important carrier of modern economic and social information and an important part of city image, its lighting field has attracted more and more attention. According to statistics, more than 80% of people's information is obtained through vision. Advertised media (Lightas Advertising< strong>Medium)< span style="text-indent:2em;line-height:1.5;">For example, if there is no light, then advertising, product promotion, city night beauty, people's nightlife, etc. will be impossible. The efficacy of an unlit advertisement is only 50% of the effect of an illuminated advertisement..

When it comes to light sources, you must understand and understand LED injection molding modules, LED lens modules, LED lens lights, LED diffuse light strips, LED counter lights, and LED back lights Lamps, etc., the following mainly explains the characteristics and operation scope of LED injection molding modules, as well as installation precautions.

LEDInjection molding module, as its name implies, is a SMD LED lamp bead surface attached to the PCB Components composed of wires pressed out by an injection molding machine. There are mainly 5050, 3528, 5630 and other models.

Common LED injection molding modules have the following characteristics:

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. The 20 units of the LED injection molding module form a string. The 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 luminous characters, blister words, other advertising lighting, etc.;

2.Hotel, KTV, shopping mall, entertainment city indoor (dark slot), exterior wall lighting, Landscape layout, stage decoration, urban lighting, etc.

3.Home shoe cabinet, wardrobe, ceiling compartment, exhibition hall, art hall, museum, office , reading room and other local decorative lighting;

LED injection moduleInstallation 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 molding 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.
