此外，所述环形安装面402固定有环形透明罩70，该环形透明罩70外罩住环形灯板50。
详述本实施例的使用方法如下：
使用时，灯头60与外部灯座安装连接，接通电源后，该驱动板30驱动环形灯板50点亮，环形灯板50产生的灯光在灯罩10的作用下朝下照射，而环形灯板50点亮后产生的热量一部分朝下发散，另一部分传递至内散热壳体42和外散热壳体41上，由于各个通风口和各散热孔的设置，以形成很好的空气对流，将内散热壳体42和外散热壳体41上的热量迅速带走，实现很好的散热效果。
本发明的设计重点在于：通过由第一水平环形板和第一竖向环形板构成外散热壳体，并配合设置通风口和各散热孔，以实现很好的空气对流效果，快速将环形灯板产生的热量散去，散热效果更佳，利于延长灯具的使用寿命，并且本产品结构简单轻巧，制造容易，成本低，值得推广使用。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
