山東LED顯示屏的運用量對比的廣泛，紅外燈發(fā)作照耀間隔不行毛病表象及處置辦法。
Shandong LED display usage contrasts to the wide, infrared light shine no problem representation and attack interval solution.
第一步：若是該商品現(xiàn)已運用1年以上，則是正常衰減，可替換同類型商品 ；
The first step: if the goods have been used for more than 1 years, is the normal attenuation, can replace the same product;
第二步：查看輸入電源電壓是不是到達額定值，能夠換用其他商標的開關(guān)電源檢測 ；
Step second: check the input supply voltage is it right? Reaches the rated value, can change detection of switching power supply for other trademark;
第二步：作業(yè)狀態(tài)下，調(diào)查紅外燈正面，是不是有不發(fā)光的LED，若是有，則是燈管有有些焚毀，需求修理 ；
The second step: operation state, being positive investigation, is it right? There is no light LED, if any, is the lamp has some burned, needs repair;
第四步：換用是非攝象機測驗，若是能到達標稱間隔，則有兩種能夠：1該攝象機感應紅外的設(shè)置被屏蔽了。2該攝象機與紅外燈不匹配，感應紅外作用差，只能替換其他類型攝象機。
The fourth step: change is non camera test, if can reach the nominal interval, there are two to 1: the camera infrared settings are blocked. 2 the camera and an infrared lamp does not match, infrared differential effect, can replace other types of camera. |
