所述散热体的顶面还形成凸台，凸台侧壁上形成上卡槽；立面反光柱的反光座周边向下形成扣环，扣环内侧形成凸粒，反光座的扣环扣在凸台上，且凸粒卡入上卡槽中使立面反光柱固定在散热体上。
所述散热体的顶面对接处形成插缝；立面反光柱的反光座对应散热体的插缝形成插槽；驱动电路位于散热体中；LED灯板的下端穿过插槽和插缝伸入散热体中，LED灯板的下端通过螺丝固定在散热体的顶面上，LED灯板的下端还通过螺丝与驱动电路固定。
所述散热体由左半部和右半部通过连接筋扣合而成，或者散热体由左半部和右半部扣合后通过螺丝固定而成。
采用上述结构后，本发明工作时，LED灯板上的LED通电发光，光线通过反光曲面及反光座的光反射，形成在270°范围内各角度间均能均匀发光的效果，即在0°～135°范围内（垂直轴对称）的任何角度之间光强差异不超过20%，且在135°～180°区间至少有5%总光通量的光强照射。本发明照射范围扩大，光的利用率大大提高。
