The energy-saving of LED display

For high energy-efficient of LED display board, I believe more and more people in the industry are well aware, nothing more than that from the bright LED lights, the driver IC, switching power supply, power consumption design, intelligent energy-saving system design and structural design These aspects implemented. Indeed, how to find the best balance in these areas, we will be able to achieve the best energy-saving effect of LED display.

In fact, consumers use a very simple way you can verify, it is to look at a few already running more than 2 years, and the effect of such high-brightness display more than 12 hours a day. More seriously, the brightness from 12000cd / m2 already dropped to 8000cd / m2 after its high operating current situation does not change, it will be more doubling the speed of light attenuation, resulting in the latter part of the decay speed several times, a high attenuation display.

In order to avoid light pollution, comply with environmental regulations, standard brightness LED display board in day and night use is not the same. As we all know, more or less to reduce the loss of brightness gradation, brightness adjustment, the greater the loss of gray. Therefore, as an initial brightness value LED display during the day to 12000cd / m2, to a night down to 800cd / m2 brightness, or extreme loss of gray, so the picture quality becomes poor night; or brightness can not be adjusted to night Use standard requirements and the formation of severe light pollution.

China has proposed a number of policies to develop intdoor LED products, but due to the current high cost led display, while facing the lack of standards, be improved thermal performance, power-driven need to re-design and other issues. Here, we talk about the heat problem of indoor LED display, along with the advent of summer, a variety of heatstroke measures all battle, LED display as the most popular outdoor display equipment, the high temperature will adversely its operation, In this hot summer we choose how their cooling equipment?

If the indoor LED display installation is the use of the column, it is best to use fan cooling fan mounted on the big screen above the back aluminum plate, up against the best, made in the form of blinds so that when it rains the rain does not into the screen. The Better Business Window is intake port, exhaust fan above the mouth, so make a complete air convection cooling effect better.
