LED modules for signs Concept

LED module lights is a widely used product among LED products. There are also great differences in structure and electronics. The simplest one is to use a circuit board and a shell with LED to form LED module lights. The complex one is to add some control, constant current source and related heat dissipation treatment to make the LED modules for signs life and luminous intensity better.

LED modules Application

SMD module LED is mainly used to display the night effects of advertising LED channel letters (acrylic, blister) and logos, and can also be used for LED light boxes and door frame decorations of shops. It uses text or logos as a medium and is installed on the top or wall of a building. Outdoor LED module can not only show the daytime effect of the logo, but also use LED as a luminous light source to show another effect at night. It is equipped with an LED lighting application control system to perform dynamic video control on text or logos. In some places with a strong entertainment atmosphere, LED backlight module have become one of the most important choices for companies to display their self-image.

LED backlight module Parameters

1. Type of lamp beads: The lamp beads in the light modules are the key components that determine the light effect and brightness. The quality of the lamp beads directly affects the overall performance of LED light modules for signs, including light uniformity, color temperature stability and service life.

2. Color: According to the color type, LED lens module can be divided into three types: single color LED module with lens (usually including 3000K, 4000K, 6000K, 7000K, 8000K, 10000K, Red, Green, Blue, Yellow), RGB LED module, and RGB addressable LED module.

3. Voltage: LED module 12v and LED module 24v produced by ADLED are widely used in the market. Module LED 12v and 24v LED module usually need to be matched with LED power supplies to work properly. When connecting LED drivers and RGB controller, it is very important to ensure the accuracy of the voltage value to avoid damage to SMD LED module due to voltage mismatch.

In recent years, ADLED has further developed 110V LED modules and LED module 220v. Compared with 12 volt LED module and LED module 24 volt, ac LED module (such as AC 110V and 230v LED module) do not require any LED transformers and can be directly connected to the mains, which greatly simplifies the installation process and is suitable for large-scale, long-distance lighting projects.

ADLED's dimmable LED module have stable performance and efficient energy consumption performance, which can meet the lighting needs of different scenes and provide safe and reliable luminous sign solutions.

4. Working temperature: LED module for sign board usually works normally between -20℃ and +60℃. The suitable temperature range of LED modules during normal operation is usually -20℃ to +60℃. Within this temperature range, LED module bulb can operate stably to ensure light efficiency and service life. If the temperature is too high or too low, it may affect the performance of the LED and even shorten the service life of LED module sign.

5. Lighting angle: ADLED's smd module design has a variety of light-emitting angles, the most common ones are 160°, 170°, 175°, 180°, 10*40°, 10*60°, 11*77°, 12*56°, 15*45°, 16*27°, etc., which can meet the needs of different application scenarios. The wide light-emitting angle smd module LED ensures uniform light distribution and effectively reduces shadows and dark areas. It is particularly suitable for application scenarios that require large-scale lighting, such as advertising light boxes, sign board, and LED displays. Among them, ADLED's 180° LED module lights is particularly outstanding, which can provide a full range of lighting effects, and the light is softer and more uniform, which greatly enhances the visual experience.

6. Brightness: In LED backlight module, brightness usually refers to luminous intensity and lumen. Luminous intensity reflects the degree of concentration of bright spots of the light source, while lumen indicates the total amount of light emitted by the light source in one second, and is usually used to measure the overall brightness output of the light. The higher the lumen, the brighter white LED backlight module.

7. Waterproof level: The waterproof level of module LED is usually measured by the IP (Ingress Protection) standard, and the most common levels include IP65, IP67, and IP68. The first digit of the waterproof level indicates the dustproof level, and the second digit indicates the waterproof level. The larger the number, the better the waterproof performance of modul light.

8. Size: It is the length, width, and height of LED backlight module. These parameters directly affect the installation method and applicable scenarios of white LED backlight module.

The length of LED module lights can vary according to the application requirements. The common length ranges from a few centimeters to tens of centimeters. Longer SMD LED module are usually suitable for large billboards or LED light boxes, while shorter LED module are suitable for fine lighting or small space applications.

The width of LED modules for signs determines the compactness and arrangement of LED modules for signs. Narrower LED modules for signs are suitable for installation in narrower light troughs or complex installation environments to ensure uniform light distribution.

The height of LED modules for signs affects the thickness and heat dissipation performance of LED module lights. LED modules with lower heights are usually used in installation occasions with limited space, while taller modules may have better heat dissipation design and are suitable for applications with long-term high-brightness operation.

9. Wire gauge: The wire gauge of high power LED module refers to the thickness of the module power cord, usually expressed in AWG (American Wire Gauge). The size of the wire gauge directly affects the current carrying capacity and the safety of the circuit. The thicker the wire diameter, the stronger the current carrying capacity; the thinner the wire diameter, the more suitable for the transmission of smaller currents.

10. The maximum length of a single connection: that is, the number of LED driver module connected in a series of flexible LED module. ADLED 12v LED module provide 20 in a string, 30 in a string, 40 in a string, and 50 in a string for selection.

11. Power: The power of 12v LED module light refers to the electrical energy it consumes during normal operation, usually expressed in watts (W). The power directly affects the brightness output and energy consumption of LED module lights. Low power modules are suitable for small signs, while high power LED module can provide stronger brightness and are suitable for large-area lighting needs.

LED modules light types

According to the color type, it can be divided into three types: single color LED modules, LED module RGB, and digital RGB LED module. single color LED module is a LED module with a single color. Generally, 3000k, 4000K, 6000K, 7000K, 8000K, 9000K, 10000K, 11000K,  red, green, blue, yellow, etc. are more commonly used; module LED RGB are LED module lights that change from several different colors. It has more colors and more changes; addressable LED module are richer than RGB. It is not only very beautiful, but also full of dynamics and more attractive.

According to the sealing performance, LED modules lights can be divided into waterproof and non-waterproof. Waterproof and non-waterproof LED light modules are mainly distinguished by the application environment. Generally, waterproof LED modules can be used for outdoor lighting and publicity. It will not have problems due to water ingress and is more suitable for harsh environment applications. Non-waterproof LED modules are mainly used indoors. Of course, waterproof LED modules are more expensive than non-waterproof ones. All LED modules provided by ADLED are waterproof LED light modules.

According to the number of LED lights, LED modules are divided into: 1 LED module, 2 LED module, 3 LED module, 4 LED module, etc.

According to the driven mode, LED modules are divided into constant current modules and constant voltage LED modules, which differ in working principles and application scenarios.

Constant current modules: drives LEDs through fixed current to ensure that each lamp bead works at the same current. The constant current LED module light has good current stability and is suitable for scenarios that require high-precision control and long-term operation. It can effectively extend the service life of the lamp bead and provide more stable light effects.

Constant voltage LED module: drives LEDs through fixed voltage, usually used in conjunction with a constant voltage power supply, and has strong flexibility. Constant voltage light modules are suitable for series and parallel connections, and are often used in scenarios such as sign lighting and advertising light boxes, and can provide a simple and convenient installation method.

According to the voltage, it can be divided into low voltage LED modules and high voltage LED modules. Both have their own advantages in application scenarios and installation methods.

Low voltage SMD LED module: The working voltage is usually 12V or 24V, and it needs to be equipped with a dedicated LED power supply for driving. LED 12v module or LED module 24v have higher safety and are suitable for use in small spaces or close contact environments. LED 12v module is still the most widely used module on the market.

High voltage SMD LED module: The working voltage is AC110V or AC220V, and it can be directly connected to the mains without the need for additional power supply, making installation more convenient. LED modul 220v or 110v are suitable for large-area outdoor lighting or long-distance wiring scenarios, such as large billboards or building lighting, reducing the installation and maintenance costs of LED power supply.

According to the application scenarios of LED modules, they can be divided into LED backlight module and edgelit LED modules, which differ in the direction of light emission, application scenarios and lighting effects.

White LED backlight module: The light source shines directly from the back, evenly covers the entire illuminated area, and provides comprehensive lighting effects. Backlight LED modules are often used for single-sided advertising signs.

Edgelight LED module: The light source shines from the side, and the light is evenly distributed by refraction or reflection. It is suitable for thin light boxes or edge-lit applications. Side emitting LED modules are often used for double-sided light box signs.
