发明实施例
本发明的实施方式
[0032] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 , 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0033] 需要说明的是， 当元件被称为 "固定于"或"设置于"另一个元件， 它可以直接在 另一个元件上或者间接在该另一个元件上。 当一个元件被称为"连接于 "另一个元 件， 它可以是直接连接到另一个元件或者间接连接至该另一个元件上。
[0034] 还需要说明的是， 本实施例中的左、 右、 上、 下等方位用语， 仅是互为相对概 念或是以产品的正常使用状态为参考的， 而不应该认为是具有限制性的。
[0035] 如图 1所示， 本发明的第一实施例中， 照明灯具包括发光光源 100、 泛光照明部 10和定向照明部 20, 泛光照明部 10与定向照明部 20均设置在发光光源 100的光路 径上， 泛光照明部 10将发光光源 100的光发散导出， 定向照明部 20将发光光源 10 0的光按预定方向导出。
[0036] 通过在同一个照明灯具中集成设置泛光照明部 10和定向照明部 20, 使得在同一 个照明灯具中同时具备泛光照明功能和定向照明功能两种照明功能， 相比于现 有技术中利用单一照明功能的照明灯具来同时实现泛光照明功能定向照明功能 的组合方案， 本发明的照明灯具不仅可以方便快捷集合两种照明功能， 而且节 约了灯具的生产成本， 同时也提供了一种集成泛光照明功能和定向照明功能的 照明灯具。
[0037] 发光光源 100可以多种发光光源形式， 例如白炽灯、 卤素灯、 荧光灯、 LED灯 、 OLED灯、 光纤照明、 激光照明等发光光源形式中的一种或任意组合。
[0038] 在第一实施例中， 发光光源 100包括第一光源 101和第二光源 102， 泛光照明部 1 0与定向照明部 20层叠设置， 具体地， 泛光照明部 10位于定向照明部 20的上方， 第一光源 101设置在泛光照明部 10的侧边上， 并且， 泛光照明部 10包括泛光透光 体 11和散光结构 12, 散光结构 12设在泛光透光体 11上， 第一光源 101发出的光由 散光结构 12发散导出， 当第一光源 101发出的光透光泛光透光体 11时， 设置在泛 光透光体 11上的散光结构 12对光进行散射， 并且安装预定设计的出光方向进行 出光。 第二光源 102发出的光由定向照明部 20定向导出并透过泛光照明部 10后射 出。 从而结合泛光照明功能和定向照明功能于一体， 形成了具有多种照明功能 相结合的照明灯具。
[0039] 具体地， 第一实施例的照明灯具的定向照明部 20包括定向导光结构 21和聚光结 构 22， 定向导光结构 21上设有多个导光面 211和多个扩展面 212， 导光面 211与扩 展面 212依次交替设置， 多个导光面 211与多个扩展面 212之间形成阶梯结构， 第 二光源 102设置在聚光结构 22上， 聚光结构 22将第二光源 102发出的光汇聚后射 向导光面 211 , 导光面 211将第二光源 102发出的光定向导出。 定向导光结构 21可 以应用透明或半透明导光材料制造的透明导光体。 通过在定向导光体结构 21上 裁切导光面 211和扩展面 212， 使得导光面 211与扩展面 212之间所形成的阶梯结 构能够接收一定范围内照射过来的第二光源 102发出的光， 然后导光面 211将光 定向导出。
[0040] 在本实施例中， 散光结构 12可以是光扩散板， 光扩散板设置在泛光透光体 11上 以对所经过的光进行散光处理， 然后将光散射出去； 也可以是光扩散网点， 光 扩散网点设置在泛光透光体 11上， 通过散光网点将所经过的光散射射出； 也可 以是具有散光功能的磨砂结构， 一般磨砂结构设置在泛光透光体 11的光入射面 上或者光出射面上， 也可以将多个小的泛光透光体组合形成大的泛光透光体， 在两个小的泛光透光体之间的连接面处设置磨砂结构； 还可以是多个散光块组 合在一起的组合结构， 多个散光块镶嵌在泛光透光体 11内部； 散光结构 12还可 以是设置在泛光透光体 11内的散光粉。
[0041] 利用第一实施例的照明灯具进行照明时， 可以利用导光面对第二光源 102的光 进行反射的方式来实现定向导光照明的目的， 因此， 导光面 211为全反射导光平 面。 第二光源 102发出的光可以直接照射到导光面 211上之后进行反射， 即该全 反射导光平面为镜面反射平面； 或者， 第二光源 102发出的光可以照射进透明导 光体之后， 由透明导光体作为光传播介质进行传播至导光面 211 , 然后由导光面 211将光全反射地进行定向导出， 该全反射导光平面为透明导光体内的导光平面
[0042] 或者， 利用第一实施例的照明灯具进行照明时， 通过类似三棱镜折射原理， 可 以将第二光源 102发出的光定向折射导出， 因此， 导光面 211为折射导光平面， 第二光源 102发出的光透过透明导光体后由折射导光平面定向折射射出。 第二光 源 102发出的光进入透明导光体进行传播， 光传播至导光面 211之后， 光从导光 面 211按照预定方向折射出去， 从而实现定向照明效果。
[0043] 如图 2所示， 其示出了本发明的第二实施例的结构示意图。 第二实施例与第一 实施例相比较， 具有以下不同之处。 第二实施例的泛光照明部 10位于定向照明 部 20的下方， 其余结构以及照明功能均相同。
[0044] 如图 3所示， 其示出了本发明的第三实施例的结构示意图。 第三实施例与第一 实施例相比较， 具有以下不同之处。 第三实施例的泛光照明部 10与定向照明部 2 0并排设置， 其余结构和照明功能均相同， 其中， 第二实施例的泛光照明部 10与 定向照明部 20导出的光向同一被照明方向射出， 从而实现对同一照明方向的照 明效果。
[0045] 如图 4所示， 其示出了本发明的第四实施例的结构示意图。 与第三实施例相比 较， 第四实施例的不同之处在于： 在泛光照明部 10与定向照明部 20并排设置的 同时， 泛光照明部 10为环状结构， 泛光照明部 10包围定向照明部 20设置。 此时 , 在被照明的区域范围内， 该区域范围的中间部分由定向照明部 20进行集中照 明， 使得该区域部分成为照明焦点， 围绕该照明焦点区域的四周， 使用泛光照 明部 10进行照亮， 使其与定向照明部 20照射的区域两处灯光强度对比鲜明， 更 加突出泛光照明功能和定向照明功能的层次感。
[0046] 如图 5所示， 其示出了本发明的第五实施例的结构示意图。 第五实施例与第二 实施例相比较， 具有以下不同之处。 第一光源 101分布在泛光照明部 10下方， 其 余结构和照明功能均相同， 通过第一光源 101将光照射透过泛光照明部 10, 此时 泛光照明部 10包括利用透明或半透明光学材料进行制造的泛光透光体 11， 并且 优选地散光结构釆用光扩散板， 光扩散板设置在泛光透光体 11的出光表面上， 然后光经过光扩散板散射之后按照预定设计的照明方向射出。
[0047] 如图 6所示， 其示出了本发明的第六实施例的结构示意图。 第六实施例与第一 实施例相比较， 具有以下不同之处。 定向照明部 20包括多个反光杯 23， 每个反 光杯 23中设有至少一个第二光源 102, 第二光源 102发出的光由反光杯 23定向导 出并透过泛光照明部 10后射出， 其余结构和照明功能均相同。 在第六实施例中 , 利用反光杯 23来替代第一实施例中聚光结构 22和定向导光结构 21， 直接利用 反光杯 23将第二光源 102发出的光进行定向射出的定向光， 以代替第一实施例中 聚光结构 22和定向导光结构 21共同作用所形成的定向光。 当然， 第六实施例中 的反光杯 23与相应的第二光源 102所形成的定向光， 也可以应用菲涅尔透镜和相 应的第二光源 102所形成的定向光来替代， 此吋， 定向照明部 20包括并列设置的 多个菲涅尔透镜， 每个菲涅尔透镜的下方设有一个第二光源 102, 即菲涅尔透镜 设置在泛光照明部 10与第二光源 102之间的位置处， 菲涅尔透镜将第二光源 102 发出的光定向导出并透过泛光照明部 10后射出； 还可以利用 TIR透镜和第二光源 102所形成的定向光来代替第六实施例中的反光杯 23与相应的第二光源 102所形 成的定向光， 此时， 定向照明部 20包括并列设置的多个 TIR透镜， 每个 TIR透镜 的下方设有一个第二光源， 即 TIR透镜设置在泛光照明部 10与第二光源 102之间 的位置处， TIR透镜将第二光源 102发出的光定向导出并透过泛光照明部 10后射 出。
[0048] 如图 7所示， 其示出了本发明的第七实施例的结构是示意图。 在第七实施例中 , 定向照明部 20包括定向导光结构 21 , 定向导光结构 21采用透明导光材料制成 , 定向导光结构 21上设有多个导光面 211和多个扩展面 212， 导光面 211与扩展面 212依次交替设置， 其中， 多个扩展面 212在同一平面内延伸， 定向导光结构 21 上相对于该平面设有多个凸起， 多个导光面 211—一对应地设在各个凸起上， 第 二光源 102发出的光与平面成夹角照射至导光面 211上， 经导光面 211全反射并透 过定向导光结构 21后定向射出。 本实施例中的泛光照明部 10设置在定向照明部 2 0的上方吋， 经定向照明部 20射出的光透过泛光照明部 10后定向射出照射到所需 照明的位置； 或者本实施例中的泛光照明部 10设置在定向照明部 20的下方吋， 经泛光照明部 10散射出的光透过定向照明部 20之后散射到所需照明的位置； 或 者定向照明部 20与泛光照明部 10并排设置。 在本实施例中， 凸起部为三角形结 构， 此时导光面为三角形凸起部的其中个平面。 当然， 定向导光结构 21也可以 用不透明的材料制成， 此时导光面为三角形凸起部上的镜面反射平面， 并且此 吋泛光照明部 10设置在定向照明部 20的上方。 第七实施例与第一、 第二、 第三 、 第四、 第五实施例中的各个实施例相比较， 除以上相对应的结构不同之外， 其余结构均相同。
[0049] 此外， 本发明的定向照明部 20所形成的定向照射光， 也可以利用定向光源进行 替代， 例如射灯、 PAR灯、 AR灯， 以直接产生定向光束而形成定向照明功能。
[0050] 以上仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的精神 和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保护范 围之内。
