href='http://www.carloalan.com/news/150.html'>http://www.carloalan.com/news/150.html</a> </div> <div class="news_content"> 随着<a href="http://www.carloalan.com/supply/128.html" target="_blank">LED显示?/a>的广泛使用,增多了很多的问题。为了更好的使用LED显示屏相关产品,我们做了一些可行性的总结?br /> 一、使用环境注意事?br /> 1.工作环境温度范?20℃≤t?0℃,工作环境湿度范围10%至90%RH?br /> 2.避免在高温、高湿度、高??盐环境下使用或存储;<br /> 3.远离易燃物品、气体、粉尘使用;<br /> 4.运输过程中避免强烈碰撞,避免尖锐物品碰撞;<br /> 5.环境温度过高或散热条件不好时,应注意不要长时间开屏使用;<br /> 6.超过规定湿度的LED显示屏在加电的情况下,会导致零部件腐蚀,甚至短路进而造成长久性损坏;<br /> <p> 7.屏体内严禁进水、铁粉等易于导电的金属物。LED显示屏应该尽量放置在低灰尘的环境,大的灰尘会对显示效果造成影响,同时灰尘过多会对电路造成损害。如果因为各种原因进水,请立即断电,直至屏体内所有元器件干燥后方可使用?</p> <p> <br /> </p> <p style="text-align:center;"> <img style="max-width:100%;" src="/uploads/image/20210526/20210526095710_5257.jpg" alt="重庆LED显示? /> </p> <p style="text-align:center;"> <br /> </p> 二、开关屏注意事项<br /> 1.开屏:先开启控制计算机使其能正常运行后再开启LED显示屏大屏幕?br /> 2.关屏:首先关掉LED屏体电源,关掉控制软件,再正确的关闭计算机;(先关计算机不关显示屏,会造成屏体出现高亮点,烧毁灯管,后果严重)<br /> 3.开关屏时间隔时间要大于5分钟?br /> 4.避免在全白屏幕状态下开屏,因为此时为大功率状态,其对整个配电系统的冲击电流大?br /> 三、供电注意事?br /> 1.LED模组为直?5V供电(工作电压?.2~5.2V),禁止使用交流供电;电源端子正负极严禁接反(注意:一旦接反就会烧坏产品甚至引发严重的火灾);<br /> 2.LED显示屏的供电电源电压?20V±10%频率?0HZ±5%?br /> 3.安全大地接触可靠,地线与零线隔离可靠,接入电源远离大功率用备;<br /> 4.如发现短路、跳闸、烧线、冒烟等异常显现时,不应反复通电测试,应及时查找问题?br /> 5.保持供电电源稳定,并做好接地保护避免雷击,在恶劣的自然条件特别是强雷电天气下不要使用;<br /> 6.必须分步给大屏幕供电电源供电,因为整屏大功率状态会对整个配电系统的产生冲击?br /> 7.LED显示屏不允许播放高亮度的全白色画面超过半个小时,以免造成电流过大,电源线发热,LED灯损坏,影响显示屏使用寿命,建议播放动态视频为主;<br /> 8.LED显示屏产品在使用过程中,不可连续开、关电源,两者操作间应相隔至?分钟?br /> 9.LED显示屏大屏幕内部线路,非专业人士禁止触碰,以免触电,或者造成线路损坏;如果出现问题,请专业人士进行检修?br /> <br /> 四、清洁注意事?br /> 1.定期清洁维护:LED全彩显示屏大屏幕长时间暴露在户外环境风吹、日晒,雨淋,即?a href="http://www.carloalan.com/supply/126.html" target="_blank">室内LED显示?/a>时间长了,屏幕上会累积较多的灰尘以及雨水冲刷的痕迹,这需要定期、及时地清洗以防影响观看效果?br /> 2.如清洁模组表面,请使用软毛刷,轻轻刷拭。禁止使用任何液体物质清洗LED模组表面,否则LED灯珠有可能损坏;<br /> 3.正确擦拭:LED显示屏大屏幕表面可以采用酒精进行擦拭,或者使用毛刷、吸尘器进行除尘,不能直接用湿布擦拭?br /> </div> <div class="pagess"> <ul> <li><div>上一?<a
