The LED module is a product composed of LEDs (light emitting diodes) arranged together according to a certain rule and then packaged together with some waterproof treatments.
LED module is a widely used product in LED products, and there are also great differences in structure and electronics. The simple thing is to use a circuit board and housing equipped with LEDs to become an LED module. With some control, constant current source and related heat dissipation treatment make LED life and luminous intensity better. It is mainly used to display the night effect of advertising fonts (acrylic, blister) and logos. It uses text or logos as the medium and is installed on the roof or wall of buildings. It can not only express the logos daytime effect, but also use LED as a light source. , Show another effect at night, coupled with LED lighting application control system, dynamic video control of text or logos, in some places with a strong entertainment atmosphere, LED light source modules have become the best way for companies to show their self-image. One of the important choices Now we mainly give a detailed description of the parameters of the LED module:
(1) Color
This is a basic parameter, and different colors are used in different occasions. According to the color type, it can be divided into three types: single-color, seven-color, and full-color single-point control. A single color is a single color and cannot be changed. Just plug in the power and it will work. Colorful means that the entire series of modules can only be of the same color, and can not achieve different colors of a single module. Simply put, all modules can only achieve the same color at the same time, and different times can be one of the seven colors. Between changes. Full-color single point means that the color of each module can be controlled, and the effect of displaying pictures and videos can be achieved when the number of modules reaches a certain level. Seven-color and full-color single points need to add a control system to achieve the effect. We will introduce the selection and application of the control system in detail in the control system chapter.
(2) Voltage
This is a very important parameter. At present, 12V low-voltage modules are 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.
(3) Working temperature
That is, the temperature at which the LED works normally. Normally, it is between -20℃~+60℃, and special treatment should be carried out if the requirement range is relatively high.
(4) Light emitting angle
The light-emitting angle of the LED module without lens is mainly determined by the LED, and the different light-emitting angles of the LED are also different. Generally, the light-emitting angle of the LED provided by the manufacturer is the angle of the LED module.
(5) Brightness
This parameter is a parameter that people pay more attention to. The brightness is a more complicated problem in LED. The brightness we usually say in LED modules is usually luminous intensity and lumen. In low power, it is usually called luminous intensity (MCD). , In high-power, it is usually said that the lumen (LM). The lumen of the module we are talking about is just adding the lumen of each LED. Although it is not very accurate, it can basically be seen. Meet the requirements, haha, personal opinion!
(6) Waterproof grade
This parameter is very important if you want to use the LED module outdoors. This is an important indicator to ensure that the LED module can work outdoors for a long time. Usually in the open air, the best waterproof rating should reach IP65
(7) Dimensions
This is relatively simple, which is commonly referred to as the length and width of high dimensions.
(8) The maximum length of a single connection
We use this parameter more when doing large-scale projects. It means the number of connected LED modules in a series of LED modules. This is related to the size of the connecting wire of the LED module. It should also be customized according to the actual situation.
(9) Power
An empirical formula for the power of LED modules: LED module power = single LED power ⅹ LED number ⅹ 1.1.
