但是目前市场上的LED景观灯不仅结构复杂，而且功能单一，传统的LED景观灯没有设置旋转式灯罩，在维修LED景观灯时需要多人合力将灯罩从支撑柱上拆卸下来对LED景观灯的内部进行维修，比较麻烦，不及时维修影响LED景观灯的美观，传统的LED景观灯不便于更换损坏的LED灯，如灯板上部分的LED灯损坏需重新更换整个新的灯板，造成浪费资源，不能节约资金。
发明内容
本发明的目的在于提供一种带有散热片的LED灯，以解决上述背景技术中提出传统的LED景观灯没有设置旋转式灯罩，不便于更换损坏的LED灯，如灯板上部分的LED灯损坏需重新更换整个新的灯板，造成浪费资源，不能节约资金的问题。
为实现上述目的，本发明提供如下技术方案：一种带有散热片的LED灯，包括底座，所述底座的上方固定有支撑柱，且底座的内部安装有蓄电池，所述支撑柱上开设有凹槽，所述凹槽内固定有转动环，所述支撑柱上靠近凹槽的上方开设有安放槽，所述安放槽的两侧分别固定有旋转扣，且安放槽的内部通过旋转扣固定有第一灯板，且第一灯板通过插头连接有第二灯板，所述转动环的一侧通过固定片固定有灯罩，所述灯罩的顶端安装有顶盖，所述灯罩外表壁的一侧通过合页连接有灯罩门，所述灯罩门的上方固定有散热片，所述散热片与蓄电池电性连接。
优选的，所述灯罩门上安装有锁孔。
优选的，所述第一灯板和第二灯板上均固定有LED灯。
优选的，所述转动环共设置有两个，且两个转动环分别固定在支撑柱的上下两端。
优选的，所述支撑柱为圆柱形结构。
本发明与现有技术相比，具有以下有益效果：
（1）本发明设置了分段的灯板，当LED景观灯内部分的LED灯损坏需要更换时，旋转固定在安放槽两侧的旋转扣，使旋转扣旋转至安放槽的一侧，将分段连接的灯板从安放槽内取出，若第一灯板或者第二灯板损坏，将损坏的第一灯板与第二灯板通过插头从灯板上分离下来，然后将新的第一灯板与第二灯板连接在灯板上，重新将灯板通过旋转扣固定在安放槽内即可，操作比较简单，节约了资源，避免了资金浪费。
（2）本发明设置了可旋转式灯罩，在维修LED景观灯时，通过转动环推动灯罩旋转，使灯罩上的灯罩门旋转至LED景观灯内出故障处，然后通过钥匙打开灯罩门对LED景观灯故障处进行维修即可，节约了维修时间，提高了工作效率，同时避免不及时维修影响LED景观灯美观的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-4，本发明提供一种技术方案：一种带有散热片的LED灯，包括底座1，底座1的上方固定有支撑柱2，且底座1的内部安装有蓄电池14，支撑柱2上开设有凹槽13，可将分段连接的灯板通过旋转扣9固定在凹槽13内，凹槽13内固定有转动环12，通过转动环12推动灯罩3旋转，使灯罩3上的灯罩门6旋转至LED景观灯内出故障处，有利于对LED景观灯故障进行维护，支撑柱2上靠近凹槽13的上方开设有安放槽8，安放槽8的两侧分别固定有旋转扣9，且安放槽8的内部通过旋转扣9固定有第一灯板10，且第一灯板10通过插头15连接有第二灯板11，为了便于拆卸更换损坏的第一灯板10与第二灯板11，转动环12的一侧通过固定片7固定有灯罩3，灯罩3的顶端安装有顶盖4，灯罩3外表壁的一侧通过合页连接有灯罩门6，灯罩门6的上方固定有散热片5，散热片5与蓄电池14电性连接。
为了便于打开灯罩门6，本实施例中，优选的，灯罩门6上安装有锁孔。
为了LED景观灯的正常使用，本实施例中，优选的，第一灯板10和第二灯板11上均固定有LED灯。
为了将灯罩3牢固的固定在支撑柱2上，本实施例中，优选的，转动环12共设置有两个，且两个转动环12分别固定在支撑柱2的上下两端。
为了便于灯罩3通过转动环12旋转，本实施例中，优选的，支撑柱2为圆柱形结构。
本发明的工作原理及使用流程：该发明在使用时，若干个第一灯板10与第二灯板11上固定的LED灯通电发光，LED景观灯内的热能通过散热片5排出，如LED景观灯内出现故障，在维修LED景观灯时，通过转动环12推动灯罩3旋转，使灯罩3上的灯罩门6旋转至LED景观灯内出故障处，然后通过钥匙打开灯罩门6对LED景观灯故障处进行维修即可，当LED景观灯内部分的LED灯损坏需要更换时，旋转固定在安放槽8两侧的旋转扣9，使旋转扣9旋转至安放槽8的一侧，将分段连接的灯板从安放槽8内取出，若第一灯板10或者第二灯板11损坏，将损坏的第一灯板10与第二灯板11通过插头15从灯板上分离下来，然后将新的第一灯板10与第二灯板11连接在灯板上，重新将灯板通过旋转扣9固定在安放槽8内即可，操作简单，节约了资源，避免了资金浪费。
