If the reflux ratio in a distillation column is increased, with all other conditions remaining unchanged, how will the content of light components in the bottom of the column change?

May I ask everyone, with an increase in the reflux ratio of a distillation column, while all other conditions remain unchanged, will the concentration of the light components collected from the bottom of the column increase or decrease?
Purity of light components at the tower top increases! The heavy components inside the tower top have decreased!
With all other conditions unchanged, an increase in the reflux ratio means that more light components enter the tower, resulting in more light components at the bottom of the tower; to maintain a constant level of light components, it is necessary to increase the heat input
