Calculating the power consumption of single color,two-color ,full-color LED display screen


General module voltage is 5 v, as long as you test out the current of module, you can calculate the power consumption of a module, then according to the number of modules per square meter, you can calculate the power of the module per square meter .Led display manufacturers test the current of module is usually according to the maximum power, that is to say, the module being tested when they are in white balance. Now let us professional LED display manufacturer  tell you how to calculate the power consumption of the whole led display screen.

1, calculate power consumption of P10 outdoor led display of single color
1) calculation method of outdoor led display of single color


Suppose outdoor led display of single color current is 5.6 A, the voltage is 5 v, then the module power = current voltage = 5.6 AX5V = 28 w.


2)  calculation of the whole led display screen power
P10 outdoor led display of single color module size is: 320 x160mm, the whole led display screen module number is about 19.5, so the whole led display screen power consumption = a single module power X the whole led display screen module number = 28 wx19. 5 = 550 w.


3) calculation of whole led display screen power consumption
In general, under white balance, the brightness and the power of the module can reach the maximum, however, when in the process of using, the whole led display screen is not always under white balance, so the power consumption of the whole led display screen will decrease, it will only use 30-50% of the white balance of power. That is to say ,the power of every square meter is between 165 w and 275 w.


4) calculation of whole led display screen electricity detail
If electricity is according to 1.5 yuan/per kw to calculate, then outdoor P10 led display of single color is 0.2475 to 0.4125 per square meter per hour of electricity. If the size of the entire led display screen is 20 square meters, with 10 hours a day, 365 days, electricity of the whole led display screen every year: (0.2475 W to 0.4125 W) 20 m2 * 10 h * 365 days * =18067.5 to 30112.5.


2.Two color outdoor LED display power consumption and electricity subsidiary


The power consumption calculation of two color is the same to that of single color. Suppose P10 outdoor double color module for 33 w, so the whole led display screen of the maximum power of 650 w, actual use of 30% 50%, namely: 195 w to 325 w. The whole led display screen annual electricity is: (0.195 KW to 0.325 KW) * 1.5 RMB 20 m2 * 10 h * 365 days * = 21352.5 to 35587.5.


3. Full-color outdoor LED display, power consumption and electricity calculation
1) regular outdoor LED display power consumption and electricity calculation method


The brightness of the outdoor LED display is usually about 5500 CD/m2-7500 CD/m2, in general, the same configuration and type of the LED led display screen, the higher brightness, the greater power. So outdoor led display screen per square meter of the biggest power consumption is about 700-1200 - w, the power commonly used by broadcasting images information is 280 w to 480 w, so if the whole led display screen is 100 square meters, annual power consumption is: 102200 kw to 175200 kw, electricity for each year: 153300 - 262800.


2) energy-saving outdoor LED display power consumption and electricity calculation method




The power consumption of energy-saving outdoor LED display is lower than the common LED display led display screen, energy saving module of general voltage is at around 3.8 V to 4.2 V, so in the case of constant current, the whole led display screen of maximum power is 480 w to 600 w, so the power commonly used by broadcasting images is 192 w to 240 w. If 100 square meters, annual power consumption of the whole led display screen is 70080 kw to 87600 kw, the annual electricity bill is 105120 - 131400.

Similarly, the power consumption of indoor single color and full color LED display and electricity calculation method is also the same method, here is no longer introduced one by one. Customers can choose the required LED display according to their own needs.
