Description

防爆灯罩
本实用新型属于照明装置零部件领域,特别涉及一种防爆灯罩。
现有的防爆灯罩,其内壁与外壁均采用光滑曲面,灯罩内壁对灯光的反射效果不明显,致使亮度受到影响。
本实用新型的目的就是提供一种能增加灯罩内壁反射灯光能力的防爆灯罩。
本实用新型的目的是这样实现的:一种防爆灯罩,包括防爆面、圆弧形罩,其特征在于:圆弧形罩底部内壁上设有环形凸起条纹,圆弧形罩的侧面内壁上延轴向方向设有竖向凸起条纹。
本实用新型由于在圆弧形罩底部及侧面内壁上设有凸起条纹,增加了灯罩对灯光的反射能力,使防爆灯照明亮度增大,并且使防爆灯罩的强度得到增加。
下面结合附图对本实用新型做进一步详细说明。
图1为本实用新型结构示意图。
图2为本实用新型俯视图。
图3为A-A剖面图。
本实用新型包括防爆面1、圆弧形罩2,其材料最好选用硅酸盐钢化玻璃,用模具压型。在圆弧形罩2底部内壁上设有环形凸起条纹4,其纵截面为锯齿形。环形凸起条纹4的数目根据罩的大小和照明需要而决定,一般为2~28条,条纹高度为1~8mm。在圆弧形罩2的侧面内壁上延轴向方向刻有竖向凸起条纹3,其截面为梯形,也可为三角形。竖向凸起条纹3的数目亦根据罩的大小和照明需要而决定,一般为22~120条,条纹高度为1~8mm。本实用新型适用于防爆灯具。

Claims (2)

1.一种防爆灯罩,包括防爆面(1)、圆弧形罩(2),其特征在于:圆弧形罩(2)底部内壁上设有环形凸起条纹(4),圆弧形罩(2)的侧面内壁上延轴向方向设有竖向凸起条纹(3)。
2.如权利要求1所述的防爆灯罩,其特征在于:所说的环形凸起条纹(4)纵截面为锯齿形;所说的竖向凸起条纹(3)截面为梯形、三角形中任一种。
