Description

一种弱光光伏长余辉发光标识 技术领域
本实用新型涉及安防发光器材领域，具体涉及一种弱光光伏长余辉发光标识。
背景技术
随着社会的进步和人们生活水平的不断发展，对于各种室内场所或地下场所例如大型公共建筑、军事设施、避难设施或地下通道、隧道等的安防保障的需求也在不断增加，特别是上述阳光一般不能直射的户内场所对能提供不间断照明以及对应急照明、诱导、或指示的标识系统的刚性需求尤为迫切。
现有发光标识一般采用市电并以连续供电模式驱动发光器件发光，但这种产品要么前期安装时需要预先铺设线路，要么后期补装时需要破坏墙面或地面结构等，安装麻烦且成本较高，而且由于供电时间长，故而耗电量相对较大，使用成本也较高。并且，某些场所由于难以架设线路与电网相连，因此使用范围受到很大的局限。
为此，有人利用长余辉发光材料的余辉发光特性制成了蓄光类(也叫夜光类)发光标识。这种蓄光类发光标识不需要铺设线路，也无需消耗电量，还能自动吸收环境光余辉发光并免维护，安装和使用的成本低，因此具有无可比拟的优越性，已作为户内应急标识、户内诱导标识、户内消防标识等受到广泛的应用。其工作原理主要利用白天的环境光源如窗户或门窗透入或散射的户外光或灯光激发，在黑暗 或晚上能利用余辉起到余辉发光作用。但现有这种的蓄光类产品由于仅靠环境光激发，在夜晚无光照或灯光关停后等条件下的余辉亮度不足，并且余辉亮度随着时间衰减过大，因此实际的使用效果不理想，使用范围受到局限。
也有人提出利用太阳能供电的发光标识，用于户外，如太阳能交通发光标识，一般在公路、道路等户外场所使用。此类产品由于户内无太阳光直射，其上光伏组件不能得到有效充电，几乎毫无用途。因为上述光伏组件一般是在户外照度条件比较充分(一般都是大于等于1000LX)的场所使用，如户外晴天的自然照度值在30000-300000LX之间，户外阴天的自然照度值在3000-10000LX之间，而户内的照度条件一般只有几百到几十LX，如室内日光灯的照度按国家照度标准在150-300LX之间，实际照度值只有100LX左右，室内自然照度则只有30-50LX，走廊日光灯的照度按国家照度标准为50LX，实际照度值只有30LX左右，自然照度则只有10-30LX之间，而上述光伏组件属于强光光伏组件，在户内低照度条件下的光伏发电效率过低，难以保证其发光亮度和发光时长，故无实际使用价值。
绝大多数户内场所在白天有一定的散射光源或通过窗户投入室内的环境光源，如地下室或走廊通道等，如何在阴雨天或夜晚不依靠市电而通过照度传感器感应环境照度等自动提供指示、诱导或辅助照明指示的功能，降低安装、使用和维护的费用，从而拓展光伏供电的蓄光类发光标识在室内低照度场所或者户外某些照度不足的环境中的应用，是业内亟待解决的问题。
