Lightning Conductor is a device used to protect a building from the effect of lightning.
A lightning conductor is made up of thick strip of metal usually of copper. The top end of the lightning conductor is pointed like sharp spike and its fixed above the highest point of building.
If lightning strikes, it will hit the top of lightning conductor and electrical energy passes safely through metal strip and into ground.
Usually Lightning conductors have pointed end because :
1. As Body narrows, the charge accumulated per unit surface area increases.
2. So, Spherical and pointed end objects have more density of charge .
3. So pointed end accepts more charge than round object.

Explanation:
Lightning rods are pointed so a charge will be concentrated at the end. If the rod had a round end the charges would spread equally around its surface. ... As long as the air is prevented from ionizing it won't conduct the lightning bolt. The purpose of the rod is to prevent ionization by discharging the ions in the air.
