LED advertising screen has gradually appeared in the streets, all kinds, dress up our city, but LED advertising screen is also a life, without proper maintenance, will not be used. So, decide what factor LED advertising screen life is it? How to remedy particularly important, let's take a look at decisions LED advertising screen Life.
Effect 1, LED light source device performance
LED lamp advertising display device is the most critical and most relevant parts and life. For LED lamp beads, mainly the following indicators: attenuation characteristics, water vapor permeability, UV resistance. If the LED advertising screen manufacturers index performance evaluation of LED lamp beads off, however, will be applied to advertising screen, it will cause a lot of quality accident, seriously affecting the life of the LED advertising screen.
2. The impact of supporting parts
In addition to the LED light source lamp beads, LED advertising screen also uses a number of other supporting components, circuit boards, plastic case, power supply, connectors, chassis and other quality problems in any one component, may lead to reduced screen life. Therefore, advertising screen life is the life of the key components of most short-lived decision. For example, LED, switching power supply, the metal casing according to 8-year standard choice of materials, process performance and protection circuit board can support its work for three years, three years later because of corrosion damage can occur, then we can only get a piece of 3 years Life display
3. Production process on the product
How the production process LED advertising screen product determines the fatigue resistance. Three anti-treatment process to produce modules poor fatigue performance is difficult to guarantee, in the temperature and humidity changes, the board will protect the surface cracks, causing performance degradation protection.
So the production process LED advertising screen display key factor in determining life. Display production involved in the production process are: Component storage and pretreatment process furnace welding process, three anti-treatment process, sealing processes. The effectiveness of the process and materials selection and matching, parameter control and quality-related operator, for the vast LED advertising screen manufacturers, the experience is very important, a factory has many years of experience in the production process more efficient will put control .
4. Display affect the work environment
Because different purposes, advertising screen working conditions vary widely. In terms of the environment, indoor temperature difference is small, no snow and UV effect; outdoor temperature difference of up to 70 degrees, plus wind and rain. Harsh environment will exacerbate the aging of the display, the work environment is an important factor affecting the life of the display.
A sense of life determined by the LED advertising screen life. LED luminous intensity of life generally declines to 50% of the initial value of the time period to life. LED as a semiconductor material, it is often said that there are 100,000 hours life, but that is evaluated under ideal conditions. While in actual use it is unattainable.
LED lamp life determined by advertising screens of life, not to say that the LED lamp life equal advertising screen life. Advertising screen at work each LED is not working at full capacity all the time, the display in the case of normal play of the video program, the life of the LED advertising screen should be about 8 times the LED lamp life, when LED lamp bead work in small current life situation can be longer.
