Describes the role of LED electronic display module components and parameters
Release date:2015-01-23 00:00 Source: Views:
With the development of photovoltaic industry, LED electronic display screen is becoming more and more widely applied, the LED module is to arrange (light emitting diode) according to certain rules together to encapsulate, plus some waterproof treatment of products. It is the core part of LED display, simple is to use an LED circuit board and the shell became an LED module.
Complex could add some control, constant current source and relevant heat treatment to make led luminous intensity and better life.

The parameters of the LED module
Color: this is a basic parameter, different color application on different occasions. According to the types of color can be divided into monochrome, full-color are two kinds of single point of control. Monochromatic is a single color, can't change. Turn on the juice can work.
Full-color single point is the ability to control to the color of each module, when the amount reaches a certain degree of module can be realized according to the effect of pictures and video. Full-color single point with control system to achieve the effect.
Voltage: this is a very important parameter, the current 12 v low voltage module is relatively common. When connect the power supply and control system to be sure to check the correctness of the voltage value, to electricity, otherwise it will damage the LED module.
Working temperature: : that is to say the LED working temperature. Usually in 18 ° C? Between + 58 ° C, if requirements higher occasion will be special processing, such as air conditioning or fan.
Light Angle: without lens of the LED module light Angle is mainly determined by the LED, the LED light Angle vary, the general manufacturer to provide the LED light Angle as the Angle of the LED module.
Brightness: when it comes to brightness, we think of the word high brightness, this parameter is people more attention to a parameter.
In the LED brightness is more complex problems, we usually in the brightness of the LED module, usually is the luminous intensity and transparency, is each module related to general degree sum come out.
Waterproof level: this is mainly for outdoor, this can ensure the LED module in one of the important indices for outdoor work for a long time. Often in the case of all outdoor waterproof level to achieve best IP65
Size: this is simpler, known as the aspect of higher dimensions.
Maximum length of a single connection: this parameter when doing the big project we use more, its meaning is in a series of LED modules, LED modules connected by number. The relationship with the LED module of the size of the cable. Also want to make to order according to the actual situation.
Power: according to experience it has a special experience formula:
Module power = the number of the power of a single LED * LED * 1.1 above is basic parameter of the LED module, usually the guest buy LED display is to pay attention to this problem, but can be by this major judgment is not suitable for your needs.
