高光通量冷阴极荧光照明灯 技术领域
本发明涉及的是一种高输出光通量的冷阴极荧光照明灯, 用于道路照明、隧道照明、 广告牌照明、 大桥、 大厦、 商场、 广场等需要大光通量照明的场合, 可替代现有高压钠 灯、 高压汞灯、 无极灯、 金卤灯、 大功率热阴极节能灯等; 更可制成光色温可调、 光强 可调、 各种不同发光色的灯和可变色灯等。 背景技术
现有技术用于路灯等照明的高光通量光源主要有低压钠灯、 高压钠灯、 高压汞灯、 无极灯、 金卤灯等。
低压钠灯的灯管明视觉发光效率约 180 lm/W, 但其显色指数甚低, 现已较少使用。 高压钠灯具有较高的发光效率、 其灯管明视觉发光效率为 90— 120 lra/W, 寿命可达 25000小时, 是目前路灯、 隧道灯的主力军, 我国约 80%的路灯用此高压钠灯, 但高压 钠灯的显色指数很低、 仅约 20— 25, 色温为 2000— 2400K, 其主要光谱位于黄光, 明视 觉 /暗视觉比约为 0. 6, 灯管暗视觉的发光效率仅约 54— 56 lm/W, 且其物体分辨率低, 即物体可见度低, 对安全不利; 而较高显色指数的白光高压钠灯, 灯管发光效率仅 37— 48 lm/W。
高压汞灯发光效率约 50 lm/W, 显色指数约为 45, 且寿命短, 目前己较少使用。 无极灯具有寿命长、 显色指数可大于 80, 灯系统发光效率 (即包括驱动器的损耗) 大于 60 lm/W等优点, 但其成本高、 电磁干扰大等有待解决的问题, 使其用途受到极大 的限制。
金卤灯的显色指数为 65— 92, 灯管发光效率约 72— 95 lm/W, 色温为 3000— 5600K, 其寿命一般为 6000— 20000小时; 但其光衰大, 光色一致性差, 系统发光效率较低, 当 外电源变化超过 ± 10%、 其发光色会变化, 其冷端位置、 灯的安装方式、 也会影响灯的 发光色和寿命, 其灯的启动时间长达 5— 15分钟、再启动需等待 10— 15分钟后才能再启 动, 灯管温度很高, 钠于石英灯管的迁移、 会使灯光变色, 石英一金属反应、 石英放气 等使灯寿命缩短, 且成本较高, 也难以制成可调光、 可变色的灯, 目前在路灯、 隧道灯 等中还较少使用。 现有技术的冷阴极荧光灯寿命可长达 2万小时、 具有幵关寿命高达一万万次以上、 灯的系统发光效率可达 55 lm/W以上、 显色指数大于 80等优点, 已被广泛应用于液晶显 示背照明, 同时也已被用于制造 2— 8W小功率螺旋型节能灯。 冷阴极荧光灯工作于气体 放电的正常辉光放电区, 其阴极电位降约 145伏、 阳极电位降约 10伏, 现有经典理论认 为其工作电流一般为 1(^〜10— 2A, (例如见"照明技术手册, 朱小清, 2004, p92) ; 一般工 作电流为 5mA, 若大于 8mA、 则放电将进入异常辉光放电区, 阴极电位降将迅速提高、 导 致发光效率下降, 同时阴极温度迅速上升、 导致阴极溅射迅速加剧、 灯寿命缩短, 其寿 命与电流的平方成反比。现有技术还认为冷阴极荧光灯的最佳发光效率的灯管内径为 1. 2 _2. 0 mm,其外径小于 2— 4. 1 mm, 若用大管径的灯管、 其发光效率将会因辐射光子的自 吸收加剧、灯管管压降下降而明显下降。据上述现有理论, 制造光通量高达几千 lm或更 高的大功率、 高发光效率的冷阴极荧光照明灯是一个尖端性技术难题, 因此, 现有技术 的冷阴极荧光灯尚不能替代高压钠灯、 高压汞灯、 无极灯、'全卤灯和大功率热阴极荧光 灯, 用于道路照明、 隧道照明、 广告牌照明、 大桥、 大厦、 商场、 广场等需要大光通量 照明的场合。
此外, 霓虹灯与冷阴极荧光灯相似、 也属于气体辉光放电发光器件。 霓虹灯用粗管 径的灯管, 较大的灯管工作电流、 例如约 25— 60mA, 几千至二万伏的工作电压工作, 灯 管电流密度小, 灯管工作温度接近室温, 其白光发光效率仅约 15— 30 lm/W, 寿命约为 3000小时; 主要用于广告显示, 至今还没有能用霓虹灯来制造路灯、 隧道灯等用的高光 通量高效长寿命照明灯。 发明内容
本发明的目的在于克服上述之不足, 突破了冷阴极荧光灯只能用细管径灯管制造小 功率灯的局限, 也突破了霓虹灯发光效率低不能用于普通照明的局限, 而提供一种高发 光效率的高光通量冷阴极荧光照明灯, 其输出光通量可高达 800— 50000 lm或更髙, 远高 于现有技术的螺旋型冷阴极荧光灯; 其灯系统发光效率可髙达 65 lm/W以上、 远高于现有 技术的霓虹灯、 也高于现有技术的螺旋型冷阴极荧光灯; 其寿命也远高于现有技术的霓 虹灯; 且本发明的高光通量冷阴极荧光照明灯可瞬时启动, 再启动也无需等待, 还可宽 范围连续调光, 更可制成不同光色温、光色温可调、 各种不同发光色的灯和可变色灯等。
