LED modules are rich in applications.
They play an important role in many fields.
In fact, understanding LED modules are simple.
With a better understanding of LED modules, I believe you can make a better buying choice.
This article will focus on three points.
These include the definition and composition of LED modules, the difference between indoor and outdoor modules, and the most important part, how to select the right LED module.
Part One what is the LED Display module
1. what is LED Module
In short, an LED module is a circuit containing various electronic accessories whose main function is to enable LEDs to play pictures or videos under control for the purpose of the user.
The composition of the LED module is not complicated, including eight components.
These eight components are LEDs, PCB, IC, Frames, Connectors, Cables, Screws or Magnets, Resistors, and Capacitors.
We do not need to grasp all the components and their functions.
Actually, we need to master only the LEDs, PCB, IC, and Cable which are the four main components.
DIP (Double In-Line Package) LEDs are the most traditional form of LED lights.
Even, most people can imagine what an LED light looks like when they recall it.
DIP LEDs have a chip that is typically encased in hard plastic and uses two straight, parallel connecting pins.
SMD LEDs are surface-mount diodes.
Because three diodes can be placed on the same chip, they are smaller and more efficient than traditional DIP LEDs.
It has better brightness and the ability to change colors.
COB (Chip on board) LEDs are the latest development in LED lighting with their higher power.
Similar to SMD chips, COB LEDs have multiple diodes, usually about nine or more.
b.different color option
The best choice for outdoor use
b.Complicated to produce
b.Display full color image
c. Abundant size options
a. Strong color consistency
d.Longer service life
|a.Complexity of maintenance|
Maintenance is the biggest problem in the long time continuous use
a.Strong heat dissipation
c.High quality of light
d. Low failure rate
a. New technologies, new products
b.Light quality is lower than SMD LEDs
PBCs for each product is customized and require different designs and materials in order to meet various needs.
For circuit boards in the LED industry, the efficiency of the board’s heat transfer is important.
With the growing interest in more efficient and cost-effective lighting methods.
However, much of the function of an LED depends on the temperature of its system.
For many companies, the solution to this problem is aluminum-based PCBs.
The main advantages of aluminum-based PCBs are the followings.
Aluminum is easy to recycle and non-toxic
Compared to other materials, aluminum is more durable and robust, and also resistant to impact and thermal damage
c. Light weight
Reduces transportation costs
d. High heat dissipation
It can effectively prevent circuit damage caused by overheating
LED driver IC is an integrated circuit (IC) that provides brightness control and backlight color control.
What we need to understand is that when the refresh rate of the IC is higher, the clearer the picture displayed by the LED module will be.
Cables are an important part of the LED module.
Usually, the cable is used together with other components to achieve the task of illumination and display.
Part Two Indoor LED Module?Outdoor LED Module? What’s the difference?
1.Indoor LED module
Indoor led module as the name implies is the LED module used in indoor placement.
The main application scenarios are the performance stage, exhibition, auditorium, etc.
2.Outdoor LED module
The Outdoor LED module as the name implies is placed in the outdoor use of the LED module.
The main application scenarios are sports fields, advertising scscreensoutdoor squares, etc.
The brightness of indoor and outdoor is different.
Outdoor light is stronger, so the display brightness of outdoor LED modules is generally not reflective after processing and need to be able to display the content even in strong light.
The outdoor environment is variable, and because outdoor LED modules are placed outdoors for a long time, so it is inconvenient to repair and maintain, so outdoor LED modules have higher requirements for dustproof and waterproofing.
(3) Observation distance
The higher the pixel, the clearer the display.
Obviously, the indoor LED module has a higher requirement for pixels.
Because indoors, people can observe the indoor LED module at a close distance.
|Type||Protection grade||Brightness||Refresh Rate||Note|
|indoor LED Module||IP54||600-1,000cd/m2||1920HZ~R3840HZ||Low power consumption, allowing for its own heat dissipation|
|outdoor LED Module||IP65/IP68||5,000-10,000cd/m2||960HZ~1920HZ||Outdoor display modules consume a lot of power.|
The higher the temperature, the higher the power consumption, which will lead to shorter service
Part Three What to consider in selecting led modules?
1. Size of LED module
The size of the LED module means the width and height of the LED module.
When preparing to buy LED modules, the first consideration must be the size.
Because the size of LED modules is simple to measure, this part will not be a problem.
It is worth noting that most LED modules are fixed in size and may require customization if you need a special size.
2. Location of installation
(1) Indoor or outdoor?
First of all, you need to clarify whether the location of the LED module installation is indoor or outdoor.
Because indoor or outdoor, the LED module type you need is very different.
(2) Frontal service or back service?
Second, you need to clarify whether your screen needs to be installed against the wall.
If wall mounting, you can consider the frontal service LED module.
(3) Rental or fixed?
Depending on your installation location, you can also have a preliminary thought on whether to choose the rental form.
The price of leasing and purchasing is definitely different.
At the same time, the rental will also have an impact on the type of LED module.
3. Control system
(1) Synchronous control
Synchronous control requires a wired link between the computer and the controller.
The effect that can be achieved by synchronous control is the screen and computer screen synchronization.
(2) Asynchronous control
Asynchronous control supports computers, cell phones, and tablets linked by way of wireless WIFI.
The effect that can be achieved by asynchronous control is that the LED module can play the screen alone, without the support of other devices’ synchronized screens.
