使用方式2：拆掉第一下壳体使用，这样光源工作时发出的热量可依次经过第三腔室、第一散热管、第一腔室和第二散热管最后向外界扩散，由于第一隔板为弧形的，因此雨水即使有少部分临时经过第二散热管也会在重力的作用下沿弧形的表面下流，不会经过第一散热管进入第三腔室内，从而在保证密封的前提下大大增加了照明灯具的散热效果，有利于保护光源，尤其适用于LED光源，该结构可应用于水上。
作为一种优选的方案，参见图2，所述第一隔板和所述上壳体的顶面之间设置有第三隔板，所述第三隔板将所述第一腔室分为引流腔室4-1和回流腔室4-2，所述引流腔室内设置有风扇15；多个所述第一散热孔中，一部分第一散热孔与所述引流腔室连通，另一部分第一散热孔与所述回流腔室连通；多个所述第二散热孔中，一部分第二散热孔与所述引流腔室连通，另一部分第二散热孔与所述回流腔室连通，该结构主要应用于大功率的光源的散热，通过风扇吸风，使得气体在第二腔室能够经过第三隔板左端的第二通孔进入回流腔室，然后经过第三隔板左端的第一通孔进入第三腔室，然后经过然后经过第三隔板由端的第一通孔进入引流腔室然后经过第三隔板右左端的第二通孔进入第二腔室 形成回流，加快了第三腔室内的热量的扩散，尤其是在拆掉第一下壳体使用时，效果更好。
实施例2，本发明提供的一种用于船舶上的防水照明灯具，参见图3，包括上壳体1和与所述上壳体可拆卸连接的第一下壳体2，所述第一下壳体为能够透光的壳体，一般为透明或半透明的；所述上壳体上设置有弧形的第一隔板3和弧形的第二隔板10，所述第二隔板位于所述第一隔板的上方，所述第一隔板的开口朝向所述第一下壳体，所述第二隔板的开口朝向所述第一下壳体，所述第二隔板与所述上壳体的顶面之间形成第一腔室4，所述第二隔板与所述第一隔板之间形成第四腔室11，所述第一隔板和第一下壳体之间形成第二腔室5；所述第一隔板上可拆卸连接有第二下壳体6，所述第二下壳体为能够透光的壳体，一般为透明或半透明的，所述第二下壳体位于所述第二腔室内，与所述第一隔板之间形成第三腔室7，所述第三腔室内设置有用于安装光源的结构，其中光源安装结构可以使用现有的机构，比如灯口，本实施例中，所述用于安装光源的结构为安装架13，所述安装架上安装有LED灯板14作为光源；所述第一隔板上对应所述第三腔室的位置设置有多个第一散热管8，所述第一散热管与所述第一散热管与所述第三腔室和第四腔室连通，其中第一散热管的高度一般设置为高于第一隔板；所述第一隔板上设置有多个第二散热管9，所述第二散热管包括散热长管9-1和散热短管9-2，所述散热短管与所述第二腔室和第四腔室连通，所述散热长管延伸至所述第一腔室内，与所述第一腔室和第二腔室连通，其中第二散热管的高度一般低于第一散热管的高度，第二散热管还可以为散热孔，所述第二隔板上设置有第三散热管12，所述第三散热管为倾斜的，与所述第一腔室和第四腔室连通，所述第三散热管靠近所述第四腔室的一端与所述第一散热管交错设置(也可以说是错位设置，即第三散热管靠近所述第四腔室的一端与所述第一散热管部正对设置)；所述上壳体包括第一筒体1-1和上盖1-2，所述第一筒体和所述上盖可拆卸连接，所述第一下壳体与所述第一筒体可拆卸连接，本实施例中，所述第一腔室内还设置有压环，所述压环与所述第一筒体和上盖均螺纹连接，所述第二隔板被所述压环抵在所述第一隔板上。当然，此时散热长管在制作时被分为两部分，这是本领域技术人员熟知的，所述第一下壳体与所述第一筒体螺纹连接；所述第一隔板上一体设置有用于连接第二下壳体的第二筒体，所述第二下壳体与所述第二筒体螺纹连接，所述第一 下壳体和所述第一筒体之间设置有密封圈；所述第二下壳体和所述第二筒体的之间设置有密封圈；所述第一筒体和所述上盖之间设置有密封圈，本实施例中，所述第二下壳体优选位于所述第一隔板的中间位置，所述第二散热管位于所述第二下壳体的外侧，散热长管位于散热短管的外侧。
上述的用于船舶上的防水照明灯具使用方式如下：
使用方式1：第一下壳体、上盖和第二下壳体均安装使用，这种结构防水性能更好，可应用于水上和水下，应用于水上时，两层壳体防水，防水效果大大增强；
使用方式2：拆掉第一下壳体和上盖使用，这样光源工作时发出的热量可依次经过第三腔室、第一散热管、第四腔室、第三散热管和第一腔室向上扩散；光源工作时发出的热量还可依次经过第三腔室、第一散热管、第四腔室、第三散热管和第二散热管最后向下扩散；由于第二隔板为弧形的且第三散热管为倾斜的，因此即使有下雨的情况雨水也不容易经过第三散热管进入第四腔室内，一般均经过散热长管流出，即使有少部分雨水经过第三散热管进入第四腔室内，也会沿着弧形的第二隔板的上表面下流经散热短管流出，当然由于第一隔板为弧形的，因此雨水即使有少部分临时经过第二散热管也会在重力的作用下沿弧形的表面下流，不会经过第一散热管进入第三腔室内，从而在保证密封的前提下大大增加了照明灯具的散热效果，有利于保护光源，尤其适用于LED光源，该结构可应用于水上。
本实施例中，所述散热短管的长度与第一隔板的厚度优选设置相同，使得散热短管正好嵌入第一隔板，第一隔板和第二隔板的总厚度与所述散热长管的长度相同，使得散热长管正好嵌入第一隔板和第二隔板，在此条件下，所述第二散热管用散热孔替代。
上述实施例中，第一隔板和第二隔板还可以设置为球面形状。
以上所述实施例仅表达了本发明的实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
