Description

中空式液冷 LED条形灯 技术领域
本发明涉及一种 LED条形灯， 具体是涉及一种利用液体进行散热并利用内 胆进行配光设计的 LED条形灯。 背景技术
目前， 市场上常见的照明灯具大都采用荧光灯及节能灯作为光源， 其普遍存 在发光体耗电量大、光效低、废弃后产生污染和使用寿命短等问题， 有时还会产 生频闪， 使人的眼睛产生疲劳， 损害人的视觉功能。
LED光源灯节电高达 80%以上， 寿命为普通灯管的 10倍以上， 几乎是免维 护的， 也不存在需要经常更换灯管、 镇流器和起辉器的问题， 而且启动快、 功率 小、无频闪、 不容易引起视疲劳。其使用寿命在 5万 -8万小时， 是目前取代传统 照明灯具中日光灯及节能灯的主要产品。 然而， 大功率 LED工作时会产生很多 热量， 其散热问题目前还没有很好的解决方法。 为解决大功率 LED灯的散热问 题， 中国专利 CN 2881326Y公开的 LED条形灯。参照图 1， 该 LED条形灯包括 灯座 1'、 发光二极管 2'、 透明面罩 4'、 电控装置 5'和兼容接口 51， 灯体加装了 特殊合金材质的金属散热片， 但这种传统 LED条形灯设计所使用的散热片为金 属材质， 需要占用额外的体积， 而且重量大、 成本高。 发明内容
为了克服目前现有产品的不足， 本发明提供一种中空式液冷 LED条形灯。 本发明为解决现有发明的技术问题而采用的技术方案是：
中空式液冷 LED条形灯， 包括 LED驱动、 LED光源、 LED基板、 配光灯 罩、 两端的电连接器和灯座， 其特征在于在所述的配光灯罩内设有中空内胆， 所 述的中空内胆和配光灯罩之间的空腔内充有传热液体， 所述的 LED基板浸置在 所述的传热液体中。
本发明的中空式液冷 LED条形灯灯具， 由于在散热腔内装有高传热性能的 传热液体 （例如， 水、 传热油、 去离子水或乙二醇溶液等）， 通过传导和对流的 方式进行热传导， 从而可以达到良好的散热效果。 同时， 由内胆和配光灯罩组成 的装有高传热性能液体的中空式散热壳体可以由轻质材料制作而成，该设计使得 散热壳体具有质轻、 环保、 耐用、 低成本等特点。 尤为重要的是， 由于本发明的 传热液体直接充注在中空式散热壳体的空腔内，因而在提高散热效果的同时不会 造成产品体积的增加，并且在基本不影响散热效果的条件下大大减轻了散热液体 的重量， 并且该中空内胆的空腔内还能设置 LED驱动， 并可供电源线穿越。
根据本发明， 所述的中空式散热壳体两端通过密封垫圈与灯座相连接。 根据本发明， 所述的传热液体可以是具有凝固点低、无腐蚀性、 阻燃且无毒 性的任何溶液，也可以是胶体状的高分子材料和纳米导热材料等，如水、传热油、 去离子水或乙二醇溶液等。 传热液体可以是导电或非导电的液体。
根据本发明， 所述的配光灯罩可以为塑料、玻璃、 亚克力或其他透明的高分 子材料， 优选为轻质材料。
根据本发明， 所述的中空内胆是可以由金属、 合金、 塑料、 玻璃、 石英等材 料制成。
根据本发明，所述的中空式散热壳体外表面可以是光滑的表面， 也可以是波 纹面等。
根据本发明， LED 驱动器可以放置在灯体外部也可以放置在灯体的中空内 胆的空腔内。
根据本发明， 中空内胆可以根据需要进行配光设计， 如： 抛光、 反光罩、 透 光棱镜、 反光涂层， 反光玻璃等有利于增强配光效果的工艺或特殊结构。
根据本发明， 条形灯可以进行模块化设计， 根据实际需要可以对条形灯进行 模组化拼装设计。 适用于广告箱体、 路灯、 照明灯、 景观灯、 隧道灯、 射灯等需 要高品质光源的场合。
根据本发明， 所述的中空内胆外表面设有支架， 所述的 LED基板设置在所 述的支架上。 一个优选的实施方式， 所述的 LED基板设置在所述的支架上开设 的滑槽内。 这种结构， 由于支架作用， LED 基板被架空设置， 与中空内胆不直 接接触， 因此， LED 基板的上下两个表面均与传热液体接触， 有利于进一步提 高导热效果。
根据本发明， 所述的 LED基板也可以紧帖中空内胆的外表面设置。
根据本发明， 所述的中空内胆通过两侧翼和配光灯罩内的凹槽连接。 根据本发明， 多个 LED光源呈单条或多条状设置在所述的 LED基板上。 附图说明
