Complexity plus some control, constant current source and related heat treatment make LED life and luminous intensity better.
Mainly for display advertising fonts LED module parameters <br> <br> Color: This is a basic parameter of different colors used in different occasions. According to the type of color, it can be divided into two types: single color and full color single point control. Monochrome is a single color and cannot be changed. Connected to the power supply will work.
The full-color single point can control the color of each module, and the effect of displaying pictures and videos can be realized when the number of modules reaches a certain level. Full color single point plus control system can achieve the effect.
Voltage: This is a very important parameter. The current 12V low voltage module is more common. When connecting the power supply and the control system, be sure to check the correctness of the voltage value before powering on, otherwise the LED module will be damaged.
Working temperature:: It is the temperature at which the LED works normally. Usually it is between -18 °C and +58 °C. If the requirements are relatively high, special treatments, such as air conditioning or exhaust fans, are required.
Luminous angle: The illumination angle of an LED module without a lens is mainly determined by the LED. The different illumination angles of the LED are also different. Generally, the illumination angle of the LED provided by the manufacturer is the angle of the LED module.
Brightness: When it comes to brightness, we think of the word high brightness. This parameter is a parameter that people pay more attention to.
Brightness is a complicated problem in LEDs. The brightness we usually say in LED modules is usually the intensity and transparency of the LEDs, which is usually the sum of the degrees associated with each module.
Waterproof rating: This is mainly for the outdoor, this important indicator to ensure that the LED module can work in the outdoor long-term. Usually in the case of all open air, it is best to achieve IP65.
Size: This is relatively simple, the maximum length is commonly referred to as the length and breadth of equal size <br> <br> a single connection: this parameter when we do large-scale projects with more than, it means that in a series LED die The number of connected LED modules in the group. This is related to the size of the connection line of the LED module. Also be customized according to the actual situation.
Power: power based on the experience it has specialized empirical formula <br> <br> single LED module = the number of LED's power * 1.1 * These are the basic parameters led module, when the guests usually have to buy led display The point of concern for this problem can also be judged by this point to suit your needs. 
With the development of the optoelectronic industry, the application of LED display screens has become more and more extensive. The LED module is a product that is arranged by putting together (light-emitting diodes) according to certain rules and adding some waterproof treatment. It is the core part of the LED display. The simple one is to use a PCB with a circuit board and a housing to form a LED module.
