背景技术
随着LED灯具的普及，低能耗、高亮度、高寿命的特点被广大用户所喜爱。筒灯作为一种能够嵌入天花板内光线下射式的照明灯具，能够保持建筑装饰的整体统一与完美，增加空间的灯光氛围，广泛应用于酒店、酒吧、家庭、咖啡厅等场所。
由于LED筒灯的光线直接射出，光线太强不柔和，存在眩目的情况，容易对人体的眼部健康产生极大地危害。但是为了控制眩光而降低LED筒灯的光源强度，又会使得LED筒灯的亮度不足。现有的LED筒灯大多不能兼容防眩光和高光效的性能，仅有的高效性防眩光的灯具也结构复杂，成本较高。
有鉴于此，确有必要提供一种筒灯，以解决上述问题。
发明内容
本申请的目的在于提供一种结构简单、成本较低、可以一灯多用的筒灯。

作为本申请的进一步改进，所述反射结构与所述光源模组可拆卸连接，所述光学结构设 在所述反射结构的下方，与所述防护面板可拆卸连接。
作为本申请的进一步改进，所述光学结构为扩散板，所述扩散板与所述防护面板连接并封闭所述壳体开口，所述扩散板的厚度为所述光学结构的安装厚度。
作为本申请的进一步改进，所述反射结构为反射杯，所述反射杯包括截锥形周壁以及相互连通的第一连接口和第二连接口，所述第一连接口与所述第二连接口相互平行，且所述第一连接口小于所述第二连接口，所述第一连接口套设在所述光源模组的外侧，所述第二连接口处设有环形限位结构，所述扩散板的外径大于所述第二连接口的直径。

光源模组2设置在壳体1的容置空间13内，并与壳体1的底板11贴合安装。具体的，光源模组2包括基板21和设在基板21上的若干发光单元22。优选的，该光源模组2为圆形的光源板，基板21为圆形，该若干发光单元22设置在圆形基板21的中心，并呈圆周形排列，以使得筒灯100出光均匀。
反射结构4为反射杯，反射杯4包括截锥形周壁41以及相互连通的第一连接口42和第二连接口43，第一连接口42与第二连接口43相互平行，且第一连接口42小于第二连接口43，第一连接口42的中心与第二连接口43的中心位于同一轴线上。光线经第一连接口42进入到反射杯4内，经截锥形周壁41的反射后经第二连接口43射出。在第二连接口43的外径上设有平行于第二连接口且向远离外径的方向延伸的环形限位结构44。优选的，该环形限位结构44为反射板的环形边沿。通过设置上小下大的反射杯4，可以提高反射杯4的反射效果，提高筒灯的光效，且增大防眩筒灯的截光角。通过设置环形限位结构44以将反射杯4限位安装在壳体1的内部。防护面板5设在壳体1的下方，与壳体1的开口14连接。优选的，防护面板5为面环，面环5上设有环形挡板51，环形挡板51的内径小于反射杯4上的环形限位结构44的内径，通过环形挡板51以将反射杯4限位安装在壳体1的内部。具体地，面环5包括环形的安装部、自靠近安装部的内边缘向壳体1的底板11方向延伸的连接部以及平行于安装部且自安装部的内边缘向壳体1的中心延伸的环形挡板51，连接部通过卡扣连接或过盈配合等方式将面环5可拆卸连接在壳体1的开口14处，方便面环5与壳体1的安装与拆卸。环形挡板51的内径小于反射杯4的环形限位结构44的内径，使得环形挡板51与环形限位结构44相抵连接，以将反射杯4限位安装在壳体1的内部。
光学结构3与反射结构4设在壳体1的容置空间13内，且光学结构3与反射结构4层叠设置在光源模组2与防护面板5之间，被光源模组2与防护面板5夹持限位。进一步地，光学结构3与反射结构4位置可调，通过调整反射结构4与不同光学机构的配合以及装配位置的变化，以实现防眩或增大光效。通过如此设置，可以在同一筒灯100的结构中实现防眩 筒灯100的截光角要求或提高筒灯100光效的效果，用户可以根据使用要求选择合适的组合状态，实现一灯多用。
请参阅图3-图5所示，在本申请的一个较佳实施例中，光学结构3与光源模组2可拆卸连接，反射结构4设在光学结构3的下方，与防护面板5可拆卸连接。光学结构3为透镜3。此时，反射结构4作为外控器件参与配光，并提供一定角度的防眩功能，实现防眩筒灯100的截光角要求。
透镜3包括环形光学部31与平板安装部32，平板安装部32围绕环形光学部31设置，以形成完整的透镜3的结构。环形光学部31远离光源模组2的一侧设有环形凸起311，另一侧对应环形凸起311的位置设有环形凹槽312。光源模组2的若干发光单元22对应设在环形凹槽312内。若干发光单元22发射出光线进入透镜3内，经过环形凹槽312和环形凸起311的折射和/或全反射后射出到反射结构4上，使得光线变得柔和，从而降低眩光与不适，达到防眩的效果，平板安装部32的厚度为透镜3的安装厚度，与常规面板的厚度相同或相近。
进一步的，反射杯4的第一连接口42套设在环形凸起321的外侧。通过如此设置，可以使得环形凸起321位于反射杯4的内部，减小透镜3的厚度，使得平板安装部32的厚度为光学结构3的安装厚度，进而减小筒灯100的高度。
请参阅图6-7所示，在本申请的另一较佳实施例内，反射结构4与光源模组2可拆卸连接，光学结构3’设在反射结构4的下方，与防护面板5可拆卸连接。此时，光学结构3’为扩散板3’，反射结构4为反射杯。反射杯4包括截锥形周壁41以及相互连通的第一连接口42和第二连接口43，第一连接口42与第二连接口43相互平行，且第一连接口42小于第二连接口43，第一连接口42的中心与第二连接口43的中心位于同一轴线上，第一连接口42套设在光源模组2的外侧，第二连接口43处设有环形限位结构44，所述扩散板3’的外径大于第二连接口43的直径。通过将反射结构4设置在光源模组2与扩散板3’之间，可以增大空间反射率，让更多的大角度光线被反射结构4折射到扩散板3’上，使得更多有效光线输出，以增大筒灯100的光效，解决发光筒灯100光效过低的问题。
进一步的，光学结构3为扩散板3’，以将射入到扩散板3’上的光线扩散的更为均匀。扩散板3’与防护结构4连接并封闭壳体1的开口14，使得扩散板3’与筒灯100的开口14相对应，保证光源能够均匀的从开口14射出进行照明，而且防止灰尘等杂质进入壳体1的内部，延长筒灯100的寿命。
扩散板3’的外径大于反射杯4的第二连接口43的直径，与反射杯4的环形限位结构44的外径相等。通过该设置，使得扩散板3’能够与面环5上的环形挡板51相抵连接，以将扩散板3’固定连接在壳体1的内部。进一步的，反射杯4的第二连接口43与扩散板3’贴合，使得扩散板3’与反射杯4更加紧密，降低光损，增大空间的反射率，使得更多的光线经反射杯4的反射进入到扩散板3’中，通过扩散板3’均匀的从壳体1的开口14输出到 筒灯100之外，增大筒灯100的光效。
进一步的，为了保证筒灯100的安装高度固定，光学结构3、3’的安装厚度固定。即透镜3的安装厚度与扩散板3’的安装厚度相等或相似。具体的，透镜3包括环形光学部31和平板安装部32。优选地，该平板安装部32为环绕环形光学部31设置的环形边缘。该平板安装部32为超薄结构，其厚度与常规面板的厚度相同或相近，即与扩散板3’的厚度相同或相近。由于反射结构4的第一连接口42套设在该环形光学部31的外侧，使得环形光学部31位于反射结构4的内部空间内，减小透镜3的安装厚度，使得透镜3的安装厚度为平板安装部31的厚度，即透镜3的安装厚度与扩散板3’的安装厚度相等或相似，从而使得光学结构3、3’的安装厚度固定，保证两种组合状态下筒灯100的安装厚度固定，从而可以实现在同一筒灯100结构中，通过简单更换光学结构3以及光学结构3与反射结构4的位置就能实现防眩筒灯100的截光角要求或提高筒灯100光效的效果，扩宽筒灯100的应用领域。
综上所述，本申请的一种筒灯100，结构简单、成本较低。在不同的应用场景中，通过简单更换光学结构3以及光学结构3与反射结构4的位置就能在同一筒灯100的结构中实现防眩筒灯100的截光角要求或提高筒灯100光效的效果，用户可以根据使用要求选择合适的组合状态，实现一灯多用。
