序章
Power supply is very important for LED display. It can be said that without power supply, the LED display cannot be lit. We often see mobile trailer LED display running around on the road, but do you know how to charge the mobile trailer LED display?
1. Does the mobile trailer LED display consume a lot of power?
Mobile trailer LED display is a star device for outdoor advertising and event sites. However, every time I see it shining, I always wonder: Does this guy consume a lot of power?
Today, let’s talk about this topic, see what factors affect its power consumption, calculate how much power it consumes, and finally talk about how to save power.
1). Things that affect power consumption
The mobile trailer LED display is actually a special type of outdoor LED screen. It has to be exposed to wind and rain, sun and rain, so it has to use brighter and more durable lamp beads, and the structure has to be more solid. In this way, the power consumption will naturally go up.
In addition, it is a full-color screen, and the red, green, and blue lamp beads must all be lit, so the power consumption must be much more than that of a single-color or two-color screen. Just like when you turn on the lights at home, which one consumes more power, one bulb or three bulbs? Obviously three!
However, some outdoor screens are quite smart now and can automatically adjust the brightness according to the ambient light. When the light is strong, the brightness is adjusted higher; when the light is weak, the brightness is adjusted lower. In this way, you can save some electricity.
2). Estimation of power consumption, have a number in mind
Let’s estimate the power consumption of the mobile trailer LED display.
Assuming that the maximum power consumption per square meter is 750 watts to 1200 watts (when the screen is in full white state), but in fact, due to different display content and brightness, the power consumption will be lower.
Let’s assume it is 400 watts to 700 watts per square meter. Then, a 10-square-meter outdoor full-color LED display, used for 10 hours a day, consumes 32 kWh to 56 kWh (that is, 32 degrees to 56 degrees of electricity).
3). Power-saving tips to make your use more enjoyable
