LED integrated commercial advertising machine

The internal heating capacity of LED transparent screens can be estimated as follows:

In the manufacturing industry, the photoelectric conversion efficiency of LED tubes is generally set at 20% -30% (estimated), so the total thermal functional loss of the screen can be estimated as 70% of the total functional loss of the screen. After deducting the heat generated by the six outward facing LED transparent screens (about 20%) from the total heat loss, the remaining amount is the heating energy of the indoor space of the LED transparent screen, which accounts for about 50% of the total functional loss of the screen body (more accurately, it is called the total average functional loss, as the monitor is unlikely to broadcast continuously on a pure white interface, with some bright and some dark).
