- waterproofing is performed by the packing 170 coupled along the outer circumference of the protective cover 160, and in particular, the sealing property may be improved through a plurality of sealing protrusions 173 formed on the packing 170.
- the lighting apparatus of the present invention is applied to various light distribution type road lighting street lights, indoor lights, parking lots, and the like.
