Considerations for powering thin and light LED displays

  With the widespread use of thin and light LED display, accompanied by an increasing number of problems in the use of a variety of objective and subjective factors, resulting in aThin and light LED displayLife expectancy is reduced, the function of the failure and other issues. In order to better use the thin and light LED display, we need to have a certain understanding of the thin and light LED display power supply considerations, the specific content is as follows:

  Considerations for powering thin and light LED displays:

  1, lightweight LED display power supply voltage: 220V ± 10% Frequency: 50HZ ± 5%.

  2, the safety of the earth contact is reliable, ground and zero line isolation is reliable, access to the power supply away from high-power power equipment.

  3, such as the discovery of short-circuit, tripping, burning line, smoke and other abnormalities, should not be repeatedly energized test, should promptly find the problem.

  4, keep the power supply stable, and good grounding protection to avoid lightning strikes, do not use in poor natural conditions, especially in the strong lightning and thunderstorms.

  5, LED module for DC +5V power supply (operating voltage: 4.2-5.2V), prohibit the use of AC power supply; power terminals positive and negative poles are strictly prohibited to reverse (Note: Once reversed will burn the product or even cause a serious fire);.

  6, must be step-by-step to the large screen power supply power supply, because the whole screen maximum power state will have an impact on the entire power distribution system.

  7, thin and light LED display is not allowed to play the highest brightness all-white screen for more than half an hour, so as not to cause excessive current, power line heating, LED lamp damage, affecting the service life of the display, it is recommended to play the dynamic video is the main;.

  8, thin and light LED display products in the use of the process, not continuous power on and off, the two operations should be separated by at least 1 minute.

  9, thin and light LED display large screen internal lines, non-professionals are prohibited from touching, so as to avoid electrocution, or cause damage to the line; if there is a problem, please ask a professional to overhaul.

  In summary, is the thin LED display power supply considerations, LED display belongs to the light-emitting heat semiconductor display products, although the theoretical value of their life can be up to 100,000 hours, but there must be good quality and established in the correct maintenance and reasonable use of the environment in order to realize.
